GeForce GTX 295 vs Geforce GTX 690

Intro

The GeForce GTX 295 has core clock 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 Rasterization Operator Units.

Compare that to the Geforce GTX 690, which uses a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular model. It features 1536 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 295 289 Watts
Geforce GTX 690 300 Watts
Difference: 11 Watts (4%)

Memory Bandwidth

Theoretically, the Geforce GTX 690 should be quite a bit faster than the GeForce GTX 295 in general. (explain)

Geforce GTX 690 384512 MB/sec
GeForce GTX 295 223776 MB/sec
Difference: 160736 (72%)

Texel Rate

The Geforce GTX 690 is a lot (about 154%) better at anisotropic filtering than the GeForce GTX 295. (explain)

Geforce GTX 690 234240 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 142080 (154%)

Pixel Rate

The Geforce GTX 690 is much (approximately 82%) more effective at AA than the GeForce GTX 295, and will be capable of handling higher resolutions more effectively. (explain)

Geforce GTX 690 58560 Mpixels/sec
GeForce GTX 295 32256 Mpixels/sec
Difference: 26304 (82%)

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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
