Nvidia was approached by the guys over at Custom PC, who asked if there were plans for the design and manufacture of a dedicated CPU by the GPU Giant. Unlike the last time when Custom PC asked Nvidia this question and CEO Jen Hsun-Huang pointedly said Nvidia "is not going into that business", this time they did not flat out deny it.
While this is not consummate proof, Custom PC speculates that pretty soon an "all-inclusive" GPU/CPU may be on the horizon, and I speculate further that it will probably have the added CUDA PPU instruction capability as well. What format it takes, or what socket it fits into will be hotly debated points until more is known and confirmed.
Speculating about what makes sense, I have to believe that Nvidia will start their own proprietary socket, with their own chipset exclusively, thus making their technology unique, and dedicated and giving less room for Intel and AMD to move in. Please remember folks, this is simply me thinking out loud. Nothing has been confirmed by Nvidia.
The Custom PC article reminds us about the AXP 2500 CPU for smart phones already made by Nvidia to make the point that the technology is ready and available within the company and so it's just a matter of time before they step up to the PC level.

Intel Corp. the proverbial Chipzilla has released news of the latest marketing name for its new family of ultra-small CPU's.
The brand name "Atom" for the ultra small chips which are designed to give end-users an entirely new design, built for low power and designed specifically for a new wave of Mobile Internet Devices and simple, low-cost PC's.
We can expect the new Atom chips to fulfill the needs on ultra-mobile PC's (UMPC) and possibly some larger PDA's. It probably also spells bad news for VIA Tech's C7 line of low power processors which have enjoyed relative good success over the past years.
The world's biggest chip maker has announced that the new "Atom" CPU is newly designed from the ground up, 45nm Intel Atom processors pack an astounding 47 million transistors on a single chip measuring less than 25mm², making them Intel's smallest and lowest power processors. These will join the ranks of other established branded Intel CPU's in their product line up, including amongst others Core 2 Quad, Core 2, Pentium, Celeron and Xeon.

The recently introduced NH-U12P CPU cooler from Noctua now has a little brother. Dubbed the NH-U9B this cooler is slightly more compact in design, using Noctua's also recently announced NF-B9 92mm fan. The heatsink has a nickel-plated finish and sports four dual heat pipes; Noctua kept the cooler quiet and compact with HTPC/small case users in mind.
Vienna, February 25th, 2008 - Three months after the introduction of the NH-U12P, which has already received more than 30 awards and recommendations from leading international websites and magazines, Noctua released today the newest version of its more compact NH-U9 series: The new NH-U9B uses the recently announced NF-B9 92mm fan and, just like its big brother NH-U12P, will be shipped with Noctua's much acclaimed NT-H1 thermal compound.
"The new NF-B9 fan enables us to replace now the popular NH-U9F with a new, even further improved model", explains Mag. Roland Mossig, Noctua CEO. "The NH-U9B is a worthy little brother for the highly acclaimed NH-U12P: Perfect for those looking for a compact, powerful and quiet premium quality cooler."
Thermalright's Ultra 120 Extreme has been the king of air coolers for quite some time now; just goes to show how hard it is for competitors in the market to go one better on the design.
Scythe however may have the answer. Dubbed the Orochi, a picture speaks a thousand words.
This cooler is an absolute beheamoth folks, boasting no less than 10 HUGE copper heatpipes, the cooler has dimensions of 120x194x155mm and weighs well over a Kg. A huge 140mm fan can be mounted on top of the heatsink, or vertically; this allowing for up to three of them working together. All sockets are supported (Intel P4 478/775 and AMD Athlon64 754/939/940/AM2/AM2+).
It's a little frightening to imagine that anyone would even attempt to mount this cooler vertically inside a typical PC chassis, that is if one even thinks they have a chance of getting it to FIT inside their enclosure, full server tower or not. At 1150g in weight, it's not exactly practical for most people. The amount of strain it would put on the motherboard; I dread to think.
Scythe in Japan have posted up details and pictures of the cooler here, but it hasn't yet been officially announced by the company worldwide. We'll be sure to bring you the press release once it pops up.
Holland based PC accessories company "Nexus" has just launched two new hardcore looking CPU coolers they call the XiR-2300 and XiR-3500. Both are very similar in design with the only notable difference being that the XiR-2300 uses aluminum cooling fins whilst the XiR-3500 uses copper.
Both coolers have a copper base along with four 6mm copper heatpipes. A 92mm PWM fan is also included with each of the coolers.
For more information and pictures, take a look at the official product page here.
The Nexus XiR coolers combine some of the most advanced technologies in the market used for CPU coolers. Heat pipes, SkiveTek and ultra-thin fins combined with a real silent temperature controlled fan delivers ultimate performance which has never been this quiet before.
XiR coolers are crafted out of the purest aluminum and copper materials. The heat sink covering the heat pipes and the copper base is made using SkiveTek technology. We have managed to apply the best technologies at the best position on the cooler. And the result is astonishing...
VIA have been fairly quiet in recent times, bringing nothing new to the scene. However, today they've announced a new low-power CPU architecture for UMPCs which is codenamed Isaiah.
According to Glenn Henry, President of Centaur Technology - a wholly owned subsidiary of VIA, the upcoming CN processor is two to four times the speed of the current VIA C7 processors at the same clock speed whilst remaining in the same thermal envelope.
Built on a 65nm process, with fab support from Fujitsu, IBM and TSMC, the Isaiah-based 'CN' processor has a die size of 60mm² and a transistor count of just 94 million. The architecture behind the chip was built from the ground up and is a superscalar and speculative out-of-order design - we'll be covering the architectural details in a later article once a few of our questions have been answered.
To help try and regain some attention towards Phenom, AMD have just announced a "Black Edition" 9600 series processor which makes for far more flexible overclocking with its fully unlocked multiplier.
As with the standard Phenom 9600, This quad core processor operates at a stock clockspeed of 2.3GHz and has 2MB of shared L3 cache and 512KB of L2 cache per core.
XBit Labs have further details on it here.
Advanced Micro Devices on Wednesday announced its new AMD Phenom 9600 Black Edition microprocessor designed specifically for gamers and overclockers and which performance can be customized using AMD's OverDrive utility directly from Microsoft Windows operating system.
Quad-core AMD Phenom processor 9600 Black Edition will operate at 2.30GHz clock-speed, 2MB shared L3 cache and 512KB dedicated L2 cache per core and will have support for dual-channel PC2-8500 (DDR2 1066MHz), just like the typical AMD Phenom 9600 chip. However, the Black Edition processor has unlocked clock multiplier, which allows enthusiasts to clock the new chip higher than 2.30GHz without any issues that are associated with overclocking.
AMD is apparently set to release their next gen IGP RS780 chipset next month which includes support for DirectX 10.
The report claims that the chipset will support AM2+ processors, HyperTransport 3.0 and PCI Express 2.0, while the IGP will support DirectX 10 and UVD (unified video decoder) 2.0 for H.264 and VC-1 decoding.
The IGP also supports DisplayPort, HDMI, DVI and HDCP. The chipset supports Hybrid CrossFireX technology, which is a similar to Nvidia's Hybrid SLI allowing the IGP to work together with discrete graphics cards for extra performance.
There is more info over at DigiTimes.
Scott Wasson from The Tech Report is on the ball - he benchmarked an AMD Phenom processor affected by the translation lookaside buffer (TLB) and L3 cache bug which is said to be rare but could cause system crashed under virtualization mode.
AMD promised a fix by way of a motherboard BIOS update but the sad news for AMD fans is that patch causes a penalty hit which Scott was kind enough to test.
Tech Report has all the detailed benchmarks here.
Across every test we ran, the difference between the Phenom 9600 with and without the TLB patch averages out to 19.8%. However, if we rule out the synthetic memory tests and consider only the application tests, that difference drops to 13.9%.
The most troubling results here are the applications where we see large performance drops with the TLB erratum workaround active, including the Firefox web browser and the picCOLOR image analysis tool. If one happens to spend a lot of time running an application whose memory access patterns don't mix well with the TLB patch, the result could prove frustrating. The BIOS-based workaround for the TLB erratum may achieve its intended result-system stability-but it comes at a pretty steep price in terms of performance.
Apparently motherboard makers will make the fix a kind of "feature" in their motherboard BIOS which can enabled or disabled. This makes much sense as the bug may not cause issues for some users.
Information has recently surfaced about Intel's plans for its new 4 series chipsets to be released in Q2 of 2008. These include the onboard graphics supporting G45 and G43, which are to be paired with the ICH10/R southbridge.
Both are DX10 compatible and carry the Vista premium logo certification. Each also will have embedded support to output HDMI, DVI, Display-Port and SDVO video up to 1080p. There is no info currently available about clock speeds and the only disguising feature between both is that the G43 lacks hardware AC1 and H.264 decoding.
During IDF Taipei this year we did manage to speak to an Intel chap about these parts and he mentioned this is the time you can expect to see Intel make a better showing in game performance but of course judging on history, that would seem a big call. Only time will tell.
Also mentioned in the roadmap is the P45 chipset but there is very little information mentioned at this stage. More to follow as we hear it.
