Microsoft to upgrade Xbox 360

Tuesday, July 10th, 2007

“experimental science-fair project SoCs shoe-horned into low-cost consumer-grade plastic boxes”.

This is how a chap describes the X360 in a letter to the Inquirer .I am not going to bash MS here, but there are a few things about the console which bother me . Recently I happened to read this at PC World.

“The real number [of Xbox 360 failure rates] is between 30 to 33 percent,” said one former EB Games employee. An anonymous Best Buy employee said the failure rate for the console was “between a quarter to a third” of all units sold”.

Those are numbers which a Chinese manufacturer of duplicate i pod’s would be ashamed of ,recently Daily Tech ran an article about the X360m failure rates which was apparently based on a field survey .

EETimes reports that MS is preparing a new game plan to upgrade the 360. Microsoft is moving its existing chips to new process technologies as it evolves toward a smaller, quieter, cooler system dubbed Falcon. It’s not clear exactly when Microsoft will roll out its Falcon version of the Xbox 360. Microsoft plans to introduce multiple flavors of the system over time, each with its own internal and external code-names. and thats the part of the story I don’t quite get. So now we have - Xbox 360, Xbox 360 Elite ,XBox 360 Falcon , and maybe in the future X360 low power edition , X360 Shakira edition :-) .

Rather than dishing out multiple avatars of the same console, I think MS should try to improve the existing X360 and provide better support and guarantee to its customers . Its gonna be fun though because MS has already said that it would require a billion-dollar charge to extend the warranty on the Xbox 360 from one to three years.

nVidia’s G92 promises 1 TeraFLOP

Friday, May 25th, 2007

The guys at The Enquirer seem to have some dough about the next generation GPU from  nVidia , In an analyst webcast, Nvidia Investor Relations and Communications VP Michael Hara stated the top end card based on the G92 graphics processor will be ready for Christmas and that it will have computing power close to 1 TeraFLOP .
Time for some cools stats now , Intel’s latest quad core Core 2 extreme QX6700 runs at 2.6 GHz and has a peak floating point performance of 50 GFLOPS, while nVidia’s G80 ( powers the 8800GTX)  has a peak floating point performance of 330 GFLOPS, AMD’s R600 can do a max 450 GFLOPS  and the STI Cell B.E does close to 250 GFLOPS at max throughput . So if the G92 rumor holds it would mean that the G92 will outperform the cell by around 4 times and its predecessor G80 by about 3 times  in terms of computing power.
One problem with GPU’s  is the inability to support 64 bit floating point operations, which is necessary for almost all supercomputing applications . On the other hand GPU’s are far cheaper than supercomputer vector processors making their use in HPC( High performance computing) justified . nVidia had promised FP64 support on GPUs by late 2007 , So is G92 the promised chip , if so its going to have a big impact on the GPGPU movement and on HPC in general.
One little concern for me is the lack of titles for the PC which can take advantage of such horsepower , Crysis is a contender and so is SC-Conviction . TeraFLOP or not it’ll be interesting to see what kind of performance can the G92 can dish out.

nVidia Quadro Plex VCS - Now on Steroids

Friday, April 27th, 2007

nVidia has strapped on 2 Quadro FX5600 GPU’s ( OpenGl version of the mighty 8800GTX) onto thier already impressive line of Quadro plex VCS ( Visual computing system) . Looks like they are getting ready to take on the emerging GPCPU market as the new workstations support GPU computing with nVidia’s CUDA programming.
GPCPU has become a lucrative market for the future and a lot of big names are pouring money into it , recently Rapidmind , a startup grabbed $10 million of VC money for their GPCPU platform, keeping in pace nVidia is pushing its graphics cards hard as a platform for massively multi-threaded processing applications.
With the new GPU’s, the total frame buffer goes up to 3Gb (1.5 Gb per GPU) FSAA (full screen anti-aliasing) goes up to 64X , and as with the 8800GTX , the GPU’s have a unified shader architecture and fully support shader model 4.0 . Now comes my favorite part - performance stats 64x SLI FSAA,16 synchronized output channels,8 HD SDI channels,60 billion pixels/sec fill rate,1 billion triangles/sec geometry performance and is able to handle up to 148 megapixels display walls. and you can have many of these Quadro Plex boxes in your visualization cluster for scalability. Oh ! I forgot to mention they cost $18000 a piece.

Vista and DX10 - GPU roadmap 2007

Wednesday, February 7th, 2007

 

With all the hype surrounding vista and with the ongoing console wars , The Nvidia 8800 GTX launch went almost unnoticed , I am not lucky enough to own one but i surely gobbled up the demo videos on you-tube , Crysis running on max settings , and the stunning UT3 are just some examples of what this graphics powerhouse can do .
Unfortunately at the Vista launch there were just two DX10 cards available , the Nvidia 8800GTX and the scaled down version of the same 8800GTS , somewhere around march ,I expect Nvidia will start shipping mainstream and lower end DX10 products based on the G86 and G84 , this most probably will coincide with the ATI R600 launch which promises to be the most advanced graphics processor ever to grace this earth , by April ATI will announce their lower end DX10 range of GPU’s and then we have the classic Red vs Green battle again for the rest of the year.
A direct impact of this will be on the pricing of the current generation of GPU’s , prices are expected to fall substantially and since it will take some time for DX10 to settle in properly , it looks like the right time to invest in a top of the line DX9 GPU .
