GeForce GTX 295 vs GeForce GTX 580 3GB

Intro

The GeForce GTX 295 uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory works at a speed of 999 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

Compare that to the GeForce GTX 580 3GB, which uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this particular card. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 580 3GB is superior to the GeForce GTX 295, but not by far. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
GeForce GTX 295 32256 Mpixels/sec
Difference: 4800 (15%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
