Intel Core 2 Duo processors 40 percent performance

Intel Corp. announced the arrival of its Intel Core 2 Duo processors 40 percent performance that the company described as its most important product since the Pentium processor released in 1993. The Core 2 Duo marks a change in Intel's approach to chip making, as the company admitted it had hit a technical wall since its 1990s dominance, which was powered by the huge leap in speed that the Pentium processor offered.

Now the company has focused on shrinking circuitry, allowing them to affix two computing engines to a single piece of silicon, which gives computers as much as 40 percent improved performance while still emitting less heat, the company says. Intel Chief Executive Paul S. Otellini said that the company planned to ship at least one million chips out in the next two months, which would get them into the PCs of computer makers in time for the holiday season. Intel Core 2 Duo processors 40 percent performance has said that systems based on the Core 2 Extreme -- Intel's processor developed for video games are already available, and Hewlett-Packard, Gateway and Dell have all announced they will sell PCs equipped with the Intel Core 2 Duo processors 40 percent performance.

This move could be just what the company needs to regain its former dominance, which has slipped over the last three years to Advanced Micro Devices (A.M.D.). The smaller company has become known for its faster and more efficient processors, leading to its acquisition of five market share points last year, according to technology research company Mercury Research. A.M.D. released a response to Intel's announcement stating it “is now quite accustomed to Intel Core 2 Duo processors 40 percent performance reacting and attempting to follow (their) lead” in the market.

Intel Core 2 Duo E8600 Review

What CPUs suit best for contemporary applications – dual- or quad-core ones? It is very hard to answer this question, so no wonder that the adherents of both concepts are constantly engaged into long fierce debates about what’s best. While top quad-core processors work at the same frequencies as the dual-core ones, there are not that many applications out there that could really use their entire potential. On the other hand, dual-core CPUs overclock better, boast more favorable thermal characteristics, and the most important thing – cost considerably less than their quad-core counterparts. That is why many enthusiasts do not hurry to spend their money on Core 2 Quad and Core 2 Extreme processors just yet.

Nevertheless, Intel seems to be working really hard on helping the users with decision making. They try to shift the users’ attention to those models that can offer maximum parallelism. Otherwise how would you explain the fact that they focus more and more on quad-core solutions, pushing dual-core CPUs into the lower-price market segment? For example, since Intel introduced 45nm production process, they haven’t increased the frequencies of their Core 2 Duo processor family even once. As a result, the top quad-core processor models have finally outpaced dual-core processors in terms of clock speeds, which doesn’t seem logical. Here I would also like to add that the new processors with promising Nehalem micro-architecture that are coming out in Q4 2008 should start conquering the market in the quad-core segment first. Thanks to simultaneous multithreading technology (SMT) these processors will be able to process up to 8 threads at the same time. Dual-core CPUs on new micro-architecture should appear in the market more than 6 months later. So those of you who don’t feel like paying extra money for additional cores will have to stay with Core 2 Duo solutions for another considerable while.

Of course, we can’ disregard the fact that Intel’s dual-core processor family is being changed dramatically, especially its lower-end models. Namely, new Wolfdale models with slashed characteristics – E7000 and E5000 – already appeared or will appear there in the nearest future. However, this evolution is meaningful only for users looking for inexpensive computers. It doesn’t take into account the interests of those who shop in $200-$300 price range. But even Intel cannot ignore for a long time this pretty large group of users who need high-frequency dual-core mainstream processors. That is why very soon the company is going to expand their Wolfdale processor family by adding one more high-speed 45nm CPU to the top of the lineup. It will work at 3.33GHz frequency. So our today’s article is going to talk about this new processor – Intel Core 2 Duo E8600.

I have to say that Core 2 Duo E8600 is also extremely interesting because it will be the first processor with E0 stepping. After that the new processor stepping will get into other 45nm Wolfdale processors, too. As a rule, the new cores bring new hopes for even better overclocking potential that is why we all look forward to the test results for the new Core 2 Duo E8600. So, let’s finish our introduction right there and move on to the actual CPU and benchmarks that we all have been looking forward to.

Dual Core Linux Performance

While nearly all of Intel's attention is focused on their newer LGA-1366 platform with the high-end Core i7 processors and then the forthcoming Core i5 series, there are still plenty of viable processors left for the LGA-775 motherboards. There are of course a number of different Core 2 Duo, Core 2 Quad, and Core 2 Extreme CPUs on the market, but beyond that Intel's Celeron family does still exist. Most computer enthusiasts simply write off the Celeron products as being too slow, but among the newer Celeron parts there are even some dual-core processors. For a forthcoming article we had picked up an Intel Celeron E1400 for looking at the Linux video decoding performance on a slow system (similar to our HD Video Playback With A $20 CPU & $30 GPU On Linux article), but as we have never published performance results for a dual-core Celeron on Linux, we have decided to get those numbers out there today for those that are interested.

The E1400 is one of four Celeron desktop processors that offer two processing cores and are codenamed Allendale. The other three processors are the E1200, E1500, and the E1600, with the difference between them largely just being the clock frequency. This Intel Celeron processor is built upon a 65nm process and Allendale is derived from Intel's Core micro-architecture. This CPU offers the normal set of features, including SSE3, Enhanced Intel SpeedStep Technology, 64-bit support, and XD bit.

The Intel Celeron E1400 is clocked at 2.0GHz, provides 512KB of L2 cache, has an 800MHz FSB, a 65 Watt TDP, and is compatible with LGA-775 motherboards. The fastest dual-core Celeron is the E1600, which is clocked at 2.4GHz, while the slowest is the E1200 and it comes clocked at 1.6GHz. All of these dual-core Celeron processors have a cost of about $50 USD.

Intel Plan 600-MHz Pentium III For September Release

Intel plans to release a 600-MHz Pentium III processor in September with a 133-MHz system bus and 256 kilobytes of integrated Level 2 cache, according to an Intel price sheet examined by Computer Retail Week. The 600-MHZ Pentium III, the first high-end Intel chip to be united with its secondary cache, will be priced at $761 in quantities of 10,000. Integrating the L2 cache onto the processor die tends to significantly increase processing power. Current Celeron processors with 128 KB of integrated L2 cache can closely match performance of a Pentium II with 512 KB of L2 cache on the Slot 1 module, for example.

The new processor also bumps up clock speeds significantly, helping Santa Clara, Calif.-based Intel distance its processors from rival Advanced Micro Devices' CPUs. At the same time, Intel will reduce pricing on its existing Pentium III processors. The 500-MHz Pentium III, initially released in March, will drop about 50 percent, from $625 this month to $299 in September.

"That's a pretty fast drop for a high-end chip," said Bill Bryant, general manager of Datel Systems, a retail chain based in San Diego. Also scheduled for release in September is a 533-MHz Pentium III with a 133-MHz system bus at $415. A 550-MHz Pentium III with a 100-MHz system bus is slated for May at $730, dropping to $696 in July and $520 in September. Pentium II processors receive similar price reductions, culminating in identical pricing schemes for the Pentium II 450-MHz and the Pentium III 450-MHz from May to September.

In addition to high-end desktop CPUs, Intel's pricing road map shows plans for the first Pentium III mobile chip with Geyserville, a code-name for a technology that reduces power consumption in high-speed processors. That 1.6-volt part will be released at 600 MHz or higher with 256 KB of on-chip L2 cache at $761. Geyserville processors are dual-mode, operating at higher clock speeds when plugged into a wall outlet and automatically switching to lower frequencies when running on a battery. The idea is to deliver desktop-equivalent speeds when drawing electrical power and dropping down to typical portable speeds when using limited resources of batteries.

Bryant said he expects Geyserville notebooks to initially appeal to businesses purchasing high-end notebooks. "Top-of-the-line notebooks run about $4,000, and by the end of the year, you are still going to be spending in that range," he said. "Those CPUs will be significant next year when the price comes down low enough that they will be in the mid-price range."

Other mobile Pentium III chips also will be released in September. Intel is scheduled to ship 1.3-volt 450-MHz and 500-MHz mobile Pentium IIIs, priced at $341 and $520, respectively.

Additional highlights in Intel's price road map include a 667-MHz Pentium III Xeon with 256 KB of integrated L2 cache set to ship in September at a $1,040 price point. The Celeron 333-MHz (with 128 KB of L2 cache on die) will drop from $81 this month to $61 in July, and a 500-MHz Celeron is slated to ship in September at $185. At the low end, Intel is expected to release shortly its new chip set, model 810, which integrates fairly high-end audio and video functionality in an effort to reduce overall system prices.

Intel to eliminate toxic lead from its microprocessor chips

Intel Corp. has announced plans to stop using lead as a soldering agent in its microprocessors. Lead is a chemical element with widespread industrial use. It is particularly useful as a semiconductor, due to its specific electrical and mechanical properties. The element, however, is a highly potent toxin known to cause blood and nervous system disorders, including mental dysfunction, especially in children.

Intel began phasing out the use of lead in its products in 2002, with the introduction of a tin-silver-copper soldering alloy. This alloy had replaced lead as a soldering agent in nearly all Intel chip sets and processors by 2004, with the exception of 0.02 grams of lead that continued to be used inside each chip.

This lead will now be eliminated in favor of the tin-silver-copper alloy, beginning with the Penryn line of processors. The company plans to have its microprocessors be lead-free by the end of the year, and to phase out lead in its 65-nanometer-process chips in 2008.

The use of toxic metals in electronics manufacture has become a serious health problem worldwide. High rates of obsolescence have contributed to a global "electronic waste" problem, in which vast quantities of electronics have been ending up as garbage, particularly in Third World countries that are paid to dispose of First World waste.

Unregulated disposal of this waste, whether by landfilling, burning or even disassembly for parts, exposes local workers, residents and ecosystems to a heavy toxic payload. Lead in particular is known for its ability to contaminate soil and groundwater.

According to Solving the E-waste Problem, a United-Nations-led alliance between three U.N. agencies, 16 businesses and several government agencies and universities, electronic waste is one of the fastest-growing types of trash in the world, with levels rapidly approaching 40 million metric tons per year.

Intel Preps Dual-Core Celeron Microprocessors – Documents.

It was just a matter of time before the leading makers of central processing units (CPUs) start to sell dual-core chips for value computers and it now seems that the time will come in the first quarter of next year, when Intel Corp. unveils dual-core Intel Celeron microprocessors aiming the most affordable personal computers (PCs).

The first Intel Celeron E1200 dual-core processor working at 1.60GHz, utilizing 800MHz processor system bus and featuring 512KB of unified secondary-level cache will emerge in the first quarter of 2008 to target cost-effective desktops. Later during the year Intel plans to add more chips into the Intel Celeron E1000 dual-core lineup, creating a comprehensive family of affordable chips with two processing engines.

Intel’s Celeron E1000 dual-core processors are set to be made using 65nm process technology and are projected to fit into 65W thermal design power envelope. The new CPUs will be drop-in compatible with all platforms that support code-named Conroe processors, e.g. Intel Core 2 Duo or Intel Pentium dual-core E2000-series.

According to documents seen by X-bit labs, Intel plans to describe the new Intel Celeron dual-core processor as delivering “entry multi-tasking experience for value-conscious customers”. Currently Intel sells Celeron processors for $34 - $59, therefore, it is possible to expect that the new E1000-series will also fit into that gap. It is interesting to note that the launch of the new Celeron dual-core chips will not mean end of life for Intel Pentium processors, which will continue to serve upper segment of low-cost desktop systems.

Given relatively low clock-speed and not a large cache, it is unlikely that Intel Celeron E1000 dual-core microprocessors will show incredible performance. Nevertheless, the forthcoming emergence of the new chips proof that multi-core technology are rushing into the value segment of the market.

The launch of low-cost dual-core Intel Celeron E1000-series processors will cause the chip giant’s rival Advanced Micro Devices to either waterfall prices of its entry-level single-core AMD Athlon LE and AMD Sempron chips, or to introduce value dual-core processors as well and reconsider pricing of single-core offerings.

Half a Willamette

The new Celeron core is based on a 128KB L2 version of the original Willamette core that the Pentium 4 debuted with in November of 2000. Unlike previous-generation Celerons, the Willamette-128 core is no different architecturally than the Pentium 4's old Willamette core. The cache organization and mapping algorithms are still the same, the only difference is that the Celeron core is only outfitted with a 128KB L2 cache instead of the 256KB cache present on the original Pentium 4.

Only having a 128KB L2 cache increases the Celeron's dependency on a high-speed memory bus. Luckily, the processor will work just fine on an 845 or 850 platform both of which offer a significantly larger amount of memory bandwidth than the i815 that the older Celerons were often paired with. With only a 128KB L2 cache, the new Celeron would appreciate the higher bandwidth i850 even more than the Pentium 4. Keep in mind that the short-lived Tualatin based Celeron processors had a 256KB L2 cache; there are situations where the new core can be outperformed by its predecessor.

Keep in mind that the first generation Pentium 4s didn't always fare so well against the Pentium III and especially the Tualatin based processors. Now with a smaller L2 cache, it will take even more for the Celeron to do well. For information on the NetBurst architecture behind the Celeron take a look at our one page explanation of its strengths and weaknesses.

The new Celeron also uses the now "old" 100MHz quad-pumped FSB, delivering a total of 3.2GB/s of FSB bandwidth. This won't be a limitation for quite a while as the Celeron won't be ramping up to clock speeds nearly as high or nearly as quickly as with the Pentium 4. The quad-pumped FSB fixes an age-old problem with the Celeron - a lack of FSB bandwidth, and when paired with DDR memory on an i845 or even RDRAM on an i850 the issue of low main memory bandwidth is nonexistent as well.

The introductory speed of the new processor is 1.7GHz running at 1.75V. Remembering that this is a 0.18-micron core helps explain the reason behind the high core voltage. Speaking of which, the new Celeron is only being introduced on the 0.18-micron process but will undoubtedly migrate down to 0.13-micron as quickly as possible. Intel still has a good amount of 0.18-micron manufacturing capacity and until those fabs get converted over for 0.13-micron production we won't see a significant push for a smaller Celeron (the 128KB L2 cache already makes it very cheap to produce).

Although the use of Intel's 0.18-micron severely limits the overclocking potential of the chip, remember that Intel got the Pentium 4 up to 2GHz on this process and that was with twice as much cache and significantly more transistors.

It's safe to assume that after the Celeron hits 2GHz Intel will transition it to a derivative of the Northwood core, most likely with a 256KB L2 cache. But until that time we have to deal with the warm-running 0.18-micron Celeron at 1.7GHz.

Intel Core I5 Computer CPU Vs Intel Core I7 920 Computer Processor Review

Specifications

The new great debate out today is between the release of the new Intel Core I5 computer CPU and the previous equivalent I7 920 computer processor. They aren't really made to be the same processor, but their performance is close enough to make it a battle of the $$$! I will describe some recent developments and how people have stacked them up against each other in day to day computers and even overclocking performance. I will keep things as simple as possible.

The new Intel Core I5 computer CPU is part of the tri-release of computer processors that have new upgrades. The Intel Core I5 computer CPU has 95 watt voltage, 2.66ghz to 3.2ghz speed with turbo boost, two channels of DDR3 1333mhz memory and 8mb of Intel's Smart Cache.

The Core I5 is just like the Core I7's that are made to be energy efficient, but are more for people that don't need the fastest machine in the world. The Turbo Boost helps you get the power you need, where you need it and when you need it. It is just a performance specification that sees that you have a demand in one area and will focus on it to provide you with the power you need.

Smart Cache is thing that many gamers love because it is an upgrade to the old cache system. It allows you to stay updated with all these multi-threaded games out today that are so demanding on your computer system.

Overclocking

When you compare two computer processors you have to take some things into consideration. You would think that the strongest would overclock the best, but that is not always true. This situation is a little weird within itself. I will explain below.

The Intel Core I5 is actually a better and stronger computer CPU than the Core I7 920, but only because of the Turbo Boost technology. This is only viewable when they are both running on stock. However, if you are overclocking the I7 920 has a much higher capability and will beat the Intel Core I5 computer processor no problem.

This partially pertains to the difference in computer CPU sockets they are using. The Intel Core I5 is using the new 1156 socket and the Intel Core I7 is using the 1366 socket. Obviously one is capable of handling a lot more data. So it is simple to see why in the overclocking world it is the winner.

Conclusion

From tabulating the dating and reviews of the computer cpu on many different stock and overclocking setups it is simple to see that these computer processors are made for exactly what Intel said. Intel Core I5 computer CPU is made for home computer users that don't play a lot of heavy duty games or computer CPU intensive programs. Intel Core I7 computer cpu is made for varying levels of gamers and video encoders and decoders that have use of that kind of power and overclocking potential.

You may be one or the other, but I have been on both sides of the game. At this moment, whatever is most cost effective is going to win the ballgame. If you are going to buy something make sure you buy it for the right purposes or you may feel like you could have gotten a better deal later on.
