GeForce GTX 295 vs Geforce GTX 670

Intro

Compare that to the Geforce GTX 670, which has GPU core speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

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

Pixel Rate

The GeForce GTX 295 will be a little bit (about 10%) better at FSAA than the Geforce GTX 670, and also will be able to handle higher resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
