The GTX 580 is the replacement for the current GTX 480, which did very well in our
review. With the GTX 580, NVIDIA hopes to not only improve performance but also improve efficiency, making this card run cooler and use less power! The specifications for the GTX 580 are as follows.
The GTX 580 uses the GF110 chipset, which is a reworked GTX 480. It does not have anymore resources but it is more power efficient. So we have 512 CUDA cores, 64 TMUs and 48 ROPs just like GF100 is capable of. Matched with the higher clock speeds, the GTX 580 has an improved pixel fill rate, texture fill rate and memory bandwidth. The texture fill rate is up from
42 billion/sec to
49.4 billion/sec while the pixel fill rate is up from
33.6 billion/sec to
37.06 billion/sec. The memory bandwidth has been increased from
177.4 GB/s to
192.4 GB/s. This brings up the GTX 580's performance by
15%-20% in games, according to NVIDIA, although a 3DMark Vantage run showed a 30% performance increase.
