NVIDIA GeForce GTX 580 is the world's fastest DirectX 11 GPU. With screaming performance and an innovative new thermal design, GeForce GTX 580 rips through the latest games while running quieter than the previous generation. GeForce GTX 580 – don't play DX11 without it. To refresh its high-end, Nvidia has not really developed new GPU, but rather refined the GF100, the GPU GeForce GTX 480/470/465. If Nvidia has decided to name this new revision of GF110 GF100 for reasons of image, it actually corresponds to what has been mentioned often as GF100 B1 is an optimized version and partly corrected GF100 used on A3 previous GeForce. During the development of GF100, Nvidia has encountered many problems, the most important of course have been corrected through several revisions of the chip. Jssen-Hsun Huang, Nvidia's CEO, moreover, we noted a few weeks ago that poor coordination between different teams working on the chip was the source of some of these problems, particularly in terms of communication between units executions and memory controllers.
It is of course not possible to refine a design forever, the day comes when we must launch a product even if it means some compromises from the original plan. This was due to Nvidia with GF100 and the A3 GeForce GTX 480. With a yield lower than expected level of production, Nvidia had to castrate the ultra high end by disabling one of its 16 blocks of threads, a first. The sequence of several revisions (A1, A2, A3) and a higher consumption than expected have made difficult the development of an efficient cooling system. This is probably the biggest mistake by Nvidia with the GeForce GTX 480 which has suffered from a poor image due to its noise and heat.
Since the GF110 is a revision of GF100 it logically includes the internal organization. This GPU is composed of four main structures, which include the GPCS each 4 DMs, the blocks of threads. Each of these DMs with 32 computing units (the "cores" in a more commercial) and 4 texturing units. This little world is attached to 6 of 64-bit memory controllers which include each 8 ROPs, responsible for writing the pixels into memory, and 128 KB of L2 cache. So we get a total of 512 units of calculation, 64 texturing units, a 384-bit memory bus, 48 ROPs and 768 KB of L2 cache. All for a huge die 3 billion transistors. If the support of computing in double precision is always present in GF110, it is not active on the GeForce derivatives, are reserved to the professional world.
For details on the architecture of GF110, our analysis related to that of GF100 remains valid. What has changed between the GF110 and GF100? Few things in the end, the main result of fine tuning a design that can more easily produce the GPU, up slightly higher in frequency and consume less, equivalent specifications, by reducing leakage currents. To do this, Nvidia said it had revalued each block of the GPU to replace, wherever possible, high-performance transistors with transistors more efficient.
Some small fixes were also made. Thus, the texturing units are now able to filter FP16 textures (and therefore FP10/11 and RGB9E5) at full speed while on the GF100 A3 they had to settle for a rate cut in half. Since this revision of the GPU had already adapted to these textures data path, which is what is most expensive to implement, we assume that filtering at full speed was indeed planned but did not work for some reason unknown to us. More than adding to the GPU, so it is rather a fix.
Nvidia also said to have added support for additional formats tiles to maximize the effectiveness of culling, the removal of hidden surfaces, in many situations. The video engine and the audio controller are not changed by cons. Unlike small GeForce 400 and GeForce GTX 480 as the GeForce GTX 580 and other possible models based on the GF110 does not bear the bit streaming HD audio formats.
