Tilera today announced its new TILE-GX line of processors, including the TILE-Gx100, the world's first 100-core CPU. According to Tilera, the 100-core part offers the highest performance of any processor on the planet by at least a factor of four.

"The launch of the TILE-Gx family, including the world's first 100-core microprocessor, ushers in a new era of many-core processing. We believe this next generation of high-core count, ultra high-performance chips will open completely new computing possibilities," said Omid Tahernia, Tilera's CEO.

While the 100-core part is not meant to run Crysis (so please don't ask) or any other desktop application, it does offer 10 times the performance per watt as Intel's fastest Nehalem-based server chips. Assuming Tilera can convince customers to switch from Intel and Texas Instruments, The TILE-Gx100 will likely end up in data centers powering cell phone network equipment and cloud computing ventures.

Tilera says its 100-core chip will start shipping in Q4 of this year.

The CPU wars in the desktop market have grown pretty stale with Intel's Core i7 architecture kicking AMD's tail, but when it comes to the server sector, the battle is starting to heat up.

Enter IBM, who at this week's Hot Chips conference officially unveiled its muscular 8-core Power7 processor. The mighty chip is expected to pack 1.2 billion transistors onto a 45nm die. Each core will boast 12 execution units, as well as 32 threads per chip and advanced pre-fetching data and instruction sets.

"I am sure Power7 will be the fastest processor around, probably faster than Intel's Nehalem in some benchmarks," said Nathan Brookwood, principal of market watcher Insight64.

Other specs include scalability up to 32 sockets, 256KB L2 cache per core, 32MB of on chip eDRAM shared L3 cache, dual DDR3 memory controllers, 100GB/s memory bandwidth per chip, and 360GB/s SMP bandwidth per chip.

Writing an operating system is no easy task, particularly for Microsoft. Having to design a piece of software that will maintain compatibility across a nearly infinite number of hardware configurations can be a daunting mission. It becomes even more difficult when hardware manufacturers implement new technologies, but the software lags behind.

Determined to not let that happen to Windows 7, Microsoft engineers have reportedly worked side by side with Intel to optimize support for its processors. In a posting made on the new Windows 7 partner blog, Microsoft’s Brandon LeBlanc highlights the results of the collaboration. “Working with Intel, Microsoft implemented a new feature called SMT parking, which provided additional support for the Windows 7 scheduler for Intel Hyper-threading Technology, enabling better performance on hyper-threaded, multi-core Intel processors.”Intel and Microsoft have also been working on optimizing boot/ shutdown/ sleep/ and resume times, which could end up giving the chipmaker a substantial edge in performance for the foreseeable future.

Intel’s rival Nvidia also posted a follow up on the partner blog outlining GPGPU functions in Windows 7, and encouraged upgraders to spring for dedicated graphics cards. Ultimately the Intel announcement is more interesting since the DX Compute found in DirectX 11 will favor both ATI and Nvidia equally and it certainly makes me worry about the growing performance gap between Intel and AMD.

Will this announcement influence your upgrade decision?

For a long time, both Intel and AMD relied on ever increasing clockspeeds for each new processor release. That still remains the case today, but to a much lesser degree. Case in point - Intel's long retired Northwood line topped out at 3.4GHz, or 200MHz faster than the zippiest Core i7 processor currently on the market.

The future of chip design has shifted to where multiple cores is now main factor, supported by larger cache, on die memory controllers, expanded instruction sets, and other secondary concerns. That's all well and good that AMD and Intel are on the same page, which puts the onus on software developers to catch up, but at least one group of researchers believes we're headed for an unpleasant surprise.

Hit the jump to find out why more cores may not translate into better performance.

In case you haven't noticed, multi-core processing has taken hold and the race is on to cram more cores onto a single die. But assuming developers can keep up, at some point, chip manufacturers are going to have address a potential major problem that could make adding more cores a useless endeavor. More specifically, a "memory wall" looms large in the not too distant future that, as Jon Stokes from ArsTechnica puts it, could make more than 16 cores pointless.

The problem stems from memory bandwidth not being able to keep pace with faster processors, whether those speed bumps come from a faster frequency or more cores. Put simply, memory is creating a bottleneck and can't feed the processor fast enough, a problem that has existed for some time. Intel and AMD have been able to mask the problem by adding more cache, but doing so doesn't overcome the memory wall, which  looks poised to really rear its ugly head as more cores are piled on to new chip packages.

"Engineers at Sandia National Laboratories, in New Mexico, have simulated future high-performance computers containing the 8-core, 16‑core, and 32-core microprocessors that chip makers say are the future of the industry," writes Samuel K. Moore at IEEE Spectrum Online. "The results are distressing. Because of limited memory bandwidth and memory-management schemes that are poorly suited to supercomputers, the performance of these machines would level off or even decline with more cores."

During a private briefing with Intel at IDF yesterday to talk about Nehalem, we were given a demo of some cool software in development that makes good use of the multi-threaded cores of the new CPU. Francois Piednoel, the Senior Performance Analyst (ie. benchmarking guru) at Intel describes Deep Viewer as a "science project" of sorts. It's an image sorting application that they acquired from an independent software developer that reminds us of Microsoft Live Labs' Seadragon technology (which is used in the recently released Photosynth online app). We're talking about near-infinite scaling of visual data (in this case photos and videos) being processed in real-time on your display.

In an attempt to tighten the screws on AMD, Intel is continuing to roll out new midrange processors early next week. Despite the fact that they aren’t officially released yet, online e-tailers are already taking orders. The CPU’s will be based on Intel’s 45-nanometer process and both Alienware & Falcon Northwest are preparing to announce systems featuring the new parts in tandem with its release. The 95 watt Q9650 currently retails for $559 on Newegg, and features a core clock speed of 3 GHz. This paired with a 12MB L2-cache, and a 1333MHz front side bus make it a solid performer for the price. In fact, this puts midrange consumers within striking distance of the Dream Machine's 150 watt QX9775 which retails for a much heftier $1550. The QX9775 runs only 200MHz faster with the same 12MB’s of L2-cache.  The main difference between the two is the 1600 MHz FSB, Skulltrail support, and the subsequent overclocking potential that comes with the extreme series.  Looking for something more modest? The Q9400 is rated for 2.66 GHz and will feature 6 MB of L2-cache on a 1333MHz FSB. For those who prefer the dual core design, the Core 2 Duo’s lineup will be receiving an update as well. The new E8600 clocks in at 3.33GHz,with 6 MB of L2-cache and  a FSB of 1,333MHz, while the lower end E7300 will sport a 2.66GHz clock with 3 MB of L2-cache, and a 1066MHz FSB. The 65 Watt E8600 is e-tailing for $279 and the E7300 will go for $144.

We’ve been calling Intel’s next-generation CPU family code-named Nehalem a Penryn-killer because, sadly, AMD’s best and brightest have hardly been that. For those who haven’t sifted the sands of the Internet, and picked the brains of OEM’s and hardware vendors for every detail of Intel’s next-gen microarchitecture, here’s your quick primer on Nehalem that’ll make you big man on campus at the next geekfest.

How Many Cores?

Most Nehalem’s will be native quad-core with all four compute cores on the same physical die. Intel says that the design of Nehalem will also let the company build an eight-core version, codenamed Beckton, for servers. Intel also hasn’t ruled out the possibility of a multi-chip version so could perhaps see a double-die Beckton with 16 cores as well.

HyperThreading Returns

An improved version of HyperThreading will find its way into the core of Nehalem. This improved simultaneous multi-threading, or SMT, will let the OS see a quad-core chip as eight cores. Although some still debate its merit, the implementation of HT in the Pentium 4 generally added 15 percent more performance in multi-threaded applications.

Read on to find out more about Intel's Nehalem.
