Where once there was three, now there are two. At least that's what we are hearing when it comes to the Intel Core i7 Nehalem processors; the Core i7-965, i7-940 and i7-920 are the only three desktop-ready parts that sport the newest architecture from Intel's engineers but it seems one of them is already on the chopping block.

AMD just made developer's lives a little bit easier, and has saved consumers from more confusion when it comes to supporting technologies such as SSE4. AMD has been working on their own version of SSE5 for some time before Intel came out with a set of instructions called AVX (Advanced Vector Extensions- not to be confused with the Larrabee architecture's vector extensions). Apparently there was a lot of overlap between SSE5 and AVX, enough so that AMD thought it prudent just to go ahead and support the extra features in AVX that SSE5 did not encompass, as well as create definitions

The AMD Athlon X2 7850 can be had at PriceGrabber for $75; the Intel Pentium E5300 for $80. AMD's offering is a dual core 2.8GHz CPU with 64KB L1 data cache, 64KB L1 instruction cache, a 512KB L2 cache per core and 2MB of latency ridden L3 cache.

Today AMD has released what looks to be the last, new 65 nm Phenom based processor. The Athlon X2 7850 is a 2.8 GHz dual core processor based on the 65 nm/B3 Phenom core. It is rated at a hefty 95 watts, though it likely rarely hits that at even full load. It is a Black Edition processor, which means it has its multiplier unlocked and users are allowe easy access to overclocking. The 7850 is derived from a full quad core, but two of the cores are disabled for this particular model. There has been some evidence that these extra cores can be unlocked by using ACC on

The Core i7 920 CPU has a new stepping, D0, and it promises to annihilate the old overclocking records. AnandTech has put up a preview of it's performance and it is an impressive change from the previous C0 stepping CPUs. They hit 4.309 GHz with memory running at 2052 @ 7-8-7-20 1T, and they did it with noticeably lower
power requirements. Check out just how much lower they were here.

BEIJING, April 8, 2009 - Celebrating the 1-year anniversary of Intel Corporation's introduction of its wildly popular Intel Atom processor family, Anand Chandrasekher, Intel senior vice president and general manager of the Ultra Mobility Group, introduced two new processors for Mobile Internet Devices (MIDs) and several other milestones during his keynote today at the Intel Developer Forum in Beijing.
Chandrasekher was joined by two other Intel executives, Craig Barrett and Pat Gelsinger,

Switching from 65nm Barcelona chips to 45nm Shanghai and the upcoming Istanbul processor just got a little bit easier for businesses. AMD is offering a 35% discount to their partners for buying upgrades.

Currently the AMD Phenom II X4 940 will run you less than $250 to pick up, just a little more affordable than a Core i7 processor. The AM2+ motherboard that you will need to run this (no AM3 boards, remember the extra pins) is also a lot less than an X58 based motherboard, so you can still manage to put together a new system in today's economic client. The performance does not beat Intel's offerings, but it does compare to them, signifying the suc

The Core 2 Duo played havoc with
AMD's desktop CPUs, now the new Nehalem based Xeon's are making the Opteron line feel even more inadequate. The new Xeon W5580 will not be a popular CPU to build a gaming PC on, that has never been it's intention. It will find a home in servers working on hard computation like graphics rendering and detailed data analysis. The numbers that The Tech Report's benchmarks returned are incredible, especially with 12 or 16 threads being run on the fluid dynamics test. You shoul

SANTA CLARA, Calif., March 30, 2009 - Intel Corporation introduced 17 enterprise-class processors today, led by the Intel Xeon processor 5500 series. They are Intel's most revolutionary server processors since addressing the market with the Intel Pentium Pro processor almost 15 years ago.
The new enterprise-class chips can automatically adjust to specified energy usage levels, and speed data center transactions and customer database queries.

ExtremeTech dug out a slew of DDR2 and DDR3 memory and paired it with a Phenom X4 810, in order to determine at what point switching to DDR3 makes sense. DDR2 is cheap but the prices of DDR3 are plummeting for the lower frequency DIMMs. Drop by for a look at the impact overclocking the CPU and switching between DDR2-1066 and 1333 versus DDR3-1600. The

Part of the reasoning behind the higher cost of Intel's Extreme Edition processors, like the Core i7-965 Extreme Edition, is that only these processors are "unlocked". Only unlocked CPUs allow you to adjust clock multipliers up rather than down from the CPU default and only unlocked CPUs allow you to adjust the memory frequency on the new integrated memory controllers on the Nehalem architecture.

Out of the box the new Phenom II X4 940 runs a nice 3.0GHz, a nice speed for a $240ish investment. For many enthusiasts that is merely the beginning, there are higher frequencies so close that it is irresistible to
overclock at least a little. Seeing as how this is a new architecture, the added challenge of being the first to hit an enormous overclock or to discover a BIOS tweak that has significan

Sunnyvale, Calif. - Feb. 25, 2009 - Advanced Micro Devices (NYSE: AMD) today announced it recently completed live public demonstrations of its upcoming six-core 45nm AMD Opteron processor, codenamed "Istanbul." Scheduled to launch in the second half of this year, "Istanbul" is expected to be the only x86 six-core processor available for two- and four-socket systems and higher.
The demonstration featured a live, seamless upgrade of a system based on 45nm Quad-Core AMD Opteron processors to "Istanbul" processors.

One month after finishing their AM2+ review, The Tech Report has now published their full review of the AM3 models that AMD has recently released. With 8 pages of benchmarks comparing over 20 processors, you really get a feel for how AMDs new chips perform as well as a look at how software is evolving to cope with multiple cores and multiple threads. They also cover overclocking procedures on these new chips, like bumping up the HyperTransport speed and hit a fairly respectable number, which you can see towards th

If you are wondering just how far a new Phenom II can be pushed, Legit Reviews has a good idea. The 810 can be pushed from 2.6 GHz all the way to
4.95GHz, the 720 BE from 2.8GHz to 4.59Ghz, as long as you use the right cooling. Along with getting an idea of where these processors top out, two other important lessons were learned. The motherboards don't mind having ice form on them and the new Phenoms are quite happy running an operating temperature below -40 degrees.
