GeForce GTX 295 vs GeForce GTX 870M

Intro

The GeForce GTX 295 has core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs along with 80 Texture Address Units and 28 ROPs.

Compare those specifications to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 941 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific model. It features 1344 SPUs along with 112 Texture Address Units and 24 Rasterization Operator Units.

GeForce GTX 870M 96000 MB/sec
Difference: 127776 (133%)

Texel Rate

The GeForce GTX 870M should be a small bit (approximately 14%) more effective at texture filtering than the GeForce GTX 295. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce GTX 295 92160 Mtexels/sec
Difference: 13232 (14%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 295 is a better choice, and very much so. (explain)

GeForce GTX 295 32256 Mpixels/sec
GeForce GTX 870M 22584 Mpixels/sec
Difference: 9672 (43%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
