GeForce GTX 295 vs GeForce GTX 470

Intro

The GeForce GTX 295 uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM is set to run at a frequency of 999 MHz on this specific model. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.

Compare all of that to the GeForce GTX 470, which comes with GPU core speed of 607 MHz, and 1280 MB of GDDR5 RAM running at 837 MHz through a 320-bit bus. It also features 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

GeForce GTX 470 133920 MB/sec
Difference: 89856 (67%)

Texel Rate

The GeForce GTX 295 should be quite a bit (about 171%) faster with regards to texture filtering than the GeForce GTX 470. (explain)

GeForce GTX 295 92160 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 58168 (171%)

Pixel Rate

The GeForce GTX 295 is a lot (about 33%) more effective at AA than the GeForce GTX 470, and will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 295 32256 Mpixels/sec
GeForce GTX 470 24280 Mpixels/sec
Difference: 7976 (33%)

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 (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
