GeForce GTX 260 vs GeForce GTX 295

Intro

The GeForce GTX 260 has a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 memory runs at 999 MHz through a 448-bit bus. It also features 192 SPUs, 64 Texture Address Units, and 28 ROPs.

Compare those specs to the GeForce GTX 295, which features a core clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 182 Watts
GeForce GTX 295 289 Watts
Difference: 107 Watts (59%)

Memory Bandwidth

In theory, the GeForce GTX 295 will be 100% faster than the GeForce GTX 260 overall, because of its higher bandwidth. (explain)

GeForce GTX 295 223776 MB/sec
GeForce GTX 260 111888 MB/sec
Difference: 111888 (100%)

Texel Rate

The GeForce GTX 295 should be quite a bit (more or less 150%) more effective at texture filtering than the GeForce GTX 260. (explain)

GeForce GTX 295 92160 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 55296 (150%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 295 is a better choice, by far. (explain)

GeForce GTX 295 32256 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 16128 (100%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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