GeForce GTX 295 vs Geforce GTX 670

Intro

The GeForce GTX 295 has a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also is comprised of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

Compare all of that to the Geforce GTX 670, which comes with core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 670 170 Watts
GeForce GTX 295 289 Watts
Difference: 119 Watts (70%)

Memory Bandwidth

In theory, the GeForce GTX 295 should perform a bit faster than the Geforce GTX 670 overall. (explain)

GeForce GTX 295 223776 MB/sec
Geforce GTX 670 192000 MB/sec
Difference: 31776 (17%)

Texel Rate

The Geforce GTX 670 will be just a bit (more or less 11%) more effective at texture filtering than the GeForce GTX 295. (explain)

Geforce GTX 670 102480 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 10320 (11%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 295 is a better choice, but not by far. (explain)

GeForce GTX 295 32256 Mpixels/sec
Geforce GTX 670 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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus 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 higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
