GeForce GTX 295 vs GeForce GTX 460

Intro

The GeForce GTX 295 comes with core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

Compare those specs to the GeForce GTX 460, which features a core clock frequency of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 192-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 24 ROPs.

GeForce GTX 460 37800 Mtexels/sec
Difference: 54360 (144%)

Pixel Rate

The GeForce GTX 295 is quite a bit (approximately 99%) faster with regards to full screen anti-aliasing than the GeForce GTX 460, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 295 32256 Mpixels/sec
GeForce GTX 460 16200 Mpixels/sec
Difference: 16056 (99%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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

Yep the 295 kicks butt.
mine is a EVGA 295 Co Op ftw.
I did try a gt 630 for a bit closer but no cigar.
192 bus width just won't beat 896 bus width.no mater what.
32256 Mpixel/sec is what counts
cuda what?
