GeForce GTX 295 vs GeForce GTX 570

Intro

Compare those specs to the GeForce GTX 570, which has GPU clock speed of 732 MHz, and 1280 MB of GDDR5 memory running at 950 MHz through a 320-bit bus. It also features 480 Stream Processors, 60 Texture Address Units, and 40 ROPs.

Texel Rate

The GeForce GTX 295 will be a lot (more or less 110%) better at AF than the GeForce GTX 570. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 48240 (110%)

Pixel Rate

The GeForce GTX 295 will be a little bit (approximately 10%) faster with regards to anti-aliasing than the GeForce GTX 570, and capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 570		29280 Mpixels/sec
	Difference: 2976 (10%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
