zrejme prvni telefony co budou vyuzivat nVidia Tegra, alespon se tedy ve ctvrtletni sprave nVidie pise ze jiz dodava Microsoftu Tegru prave do techto chystanych telefonu
"After eight years of providing innovative, high-quality graphics cards to the market, we regret to say that this category is no longer profitable for us, although we will continue to evaluate it going forward", said John Slevin, chairman of BFG Technologies. "We will continue to provide our award-winning power supplies and gaming systems, and are working on a few new products as well. I'd like to stress that we will continue to provide RMA support for our current graphics card warranty holders, as well as for all of our other products such as power supplies, PCs and notebooks."
A high-ranking executive Silicon Graphics Inc. (SGI) said in an interview that the latest Nvidia Corp.’s Tesla T20 computing processors based on Fermi architecture dissipate so much heat that SGI was looking forward alternative products that could substitute Nvidia’s chips inside the company’s high-performance computing (HPC) servers...
...Mr. Mannel said that computing processors with very high heat dissipation – such as Nvidia Tesla C2050/M2050 that have 225W thermal design power – create additional amount of work since those modules require more advanced cooling solutions. The increased temperatures also result in “worse failure profile” as well as increased costs due to necessity to spend more on design, manufacturing and maintenance. Finally, in certain cases overheating graphics cards force end-users to scale up the cooling infrastructure" to meet the higher ambient temperature demands in HPC data centers.
According to Mannel, when SGI first evaluated GPGPUs, Nvidia appeared to be a better solution, but now things are looking rather different. The report claims that Nvidia is looking for alternatives for Nvidia Tesla and AMD’s FireStream seems to be the most obvious choice. Intel Corp.’s Larrabee-derivative for HPC seems to be far away, as a result, FireStream has a chance...
At a rendezvous in San Francisco, Avner Ronen told us the decision to abandon Tegra 2 was about performance and nothing more: "The major problem we had with the Tegra 2 was support for high-profile HD playback," he said. "You can do high-profile VC-1 with Tegra 2, but not H.264." It was a problem of bitrate, he told us, and while NVIDIA's dual-core Tegra T20 was apparently not up to the task, the team had internally tested Intel's CE4100 decoding streams at up to 90 megabits per second.



Napadá mě, že když už bude CUDA x86 compiler, možná se dočkáme i optimalizace PhysX runtime pro x86 CPU (souvislost s PhysX SDK 3.0?)![]()
CUDA GPU to není, ale pokud je tam kolonka pro DP produkt vydaný roku 2009, tak to může být jedině Cypress, neboť první karta s GF100 byla vydaná na přelomu března/dubna 2010Mirek Jahoda píše:Cypress se dá označit jako CUDA GPU?

Otazkou je, zda spravna cesta k zvyseni vykonu Fyziky_CPU spociva v optimalizaci vykonu, ci optimalizaci vypoctu (dynamicke prizpusobeni rozsahu vypoctu).
Clearly, with the proper coding and infrastructure, PhysX could take advantage of several cores in a modern CPU. For example, Westmere sports 6 cores, and using two cores for physics could easily yield a 2X performance gain. Combined with the benefits of vectorized SSE over x87, it is easy to see how a proper multi-core implementation using 2-3 cores could match the gains of PhysX on a GPU...
