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.
It appears that Sony did indeed change the CPU in the new 40GB version of the PS3 to a 65nm chip after all, despite what you might've read earlier. It took a while for Sony to admit to doing so, but Kazuo Hirai, the president of SCEI came clean and said that the Cell Broadband Engine in the 40GB model is indeed produced using a 65nm process.
The story started in Japan with some journalists noticing a much lower power usage of the 40GB model, although Sony did initially deny that there were any new chips in the latest revision of the console. However, now the company has come clean and although the Cell processor has had its die shrunk, the RSX graphics chip remains at 90nm.
The Japanese website Impress PC Watch has stripped one of the new consoles and they've also done some power testing. The old model draws 170W at boot, while the new model only draws 117W. During DVD playback we're looking at 198 versus 140W and playing Ridge Racer 7 the old model draws 191W while the new model only draws 136W. It seems strange that the PS3 draws more power during DVD playback than when you're playing games though.
The picture above is of the new motherboard which is missing the Emotion Engine of the PS2 which the 20 and 60GB models came with. There are plenty of pictures on how to disassemble the PS3, although PC Watch isn't suggestion you should do so, as it'll void your warranty. The PS3 looks quite different from the Xbox 360 internally, which shows that it has nothing in common with a PC, unlike the Xbox 360 which has borrowed heavily from the PC platform.
You can find a babelfish translated link of the PC Watch article here and there are loads of pictures to have a look at if you want to see more of the internals of a PS3.
A new CPU cooler has made its way into ASUS' Triton series this week dubbed the Triton 77.
This new Triton 77 incorporates innovative features that include the up-way air flow technology, high-density fins, dynamic fan speed control and pure copper heat pipes to deliver efficient heat dissipation for the latest quad-core processors. With its lightweight and compact cooler size, the Triton 77 is also compatible with a wide range of motherboards and chassis.
Quite an interesting concept with the fan being mounted underneath, not something you see often that's for sure. As to just how effective it is, we'll have to wait for the reviews to show up.
The announcement can be found here folks.
With ASUS' innovative Up-way air flow cooling technology, the Triton 77 provides up to 15% enhanced cooling efficiency by rapidly transferring heat directly from the CPU and dissipating it out from the chassis with the case fan. Additionally, it also carries the heat produced by the VRM (Voltage regulation modules) surrounding the CPU to reduce their temperature by 10-15°C for system reliability and stability.
Some benchmark results for AMD's upcoming quad-core based "Phenom X4" have surfaced on the web which puts it up against a few of Intel's Core 2 processors in the new Crysis demo.
It would be really nice to see AMD apply some real pressure back on Intel once again but if these benchmark numbers are anything to go by It's unfortunately easy to assume that isn't going to happen. The AMD processor gets its rear handed to it by all three Intel processors even when overclocked to 3GHz.
Thanks to Expreview for the early look at K10 quad-core performance, as depressing as it is.
Thanks to the built-in CPU/GPU branchmark system of Crysis, we can easily finish CPU/GPU branchmark on this game. The GPU branchmark will finish today,before that let's have some branchmark score of CPUs:QX6850,QX9650,Phenom X4.
For more balance, Phenom X4 is already OC to 3GHz(15x200MHz) .Because the built-in Memory controller of Phenom have some auto setting funtion, so the memory frenquency is set to 375MHz automatically.
The lads at XBit have posted up some details about AMD's upcoming lineup of IGP based motherboard chipsets, these to sport integrated DirectX 10 graphics, hybrid Crossfire tech, HDMI, DisplayPort and more.
Advanced Micro Devices plans to update its family of chipsets with built-in DirectX 10-compliant graphics cores in January, 2008, sources with knowledge of the matter revealed. The new products will help AMD to offer more competitive platforms, but the company will still have offer somewhat outdated integrated graphics solutions during holiday season.
Today Intel officially lifted the curtain on their new high-end X38 Express desktop chipset, normally it would be after this point that we finally get a real taste of the performance and features on tap, but with X38 we were lucky enough to get plenty of treats here and there well before this official unveiling today thanks to all the early coverage surfacing on hardware review websites in the last 3/4 weeks in particular.
Nonetheless, to coincide with the official release is a bunch of fresh coverage floating around on the web; You can check it out via the below links to see if X38 will be your next upgrade path :-
No doubt we'll now begin to see several press releases being distributed from motherboard makers showing off their variants based on X38. I'll bring them to you as they come in folks.
Back in May, Intel launched the P35 Express chipset, a replacement for its popular 965P. Classified as a mid-range product, the P35 added official support for front-side bus speeds up to 1333MHz, came bundled with a new ICH9R south bridge chip, and became the first desktop chipset to support DDR3 memory. Enthusiasts lapped it up, and in the months since, we've seen a wave of P35 motherboards that offer great performance and tantalizing overclocking potential.
Intel's mid-range chipsets have traditionally been excellent, so the P35's success wasn't a surprise. That success also raised expectations for Intel's new high-end core logic chipset: the X38 Express. This isn't a new trend; the all-around goodness typical of Intel's mid-range chipsets has long made it difficult for the company's flagship offerings to shine.
