VS

GeForce GTX 295 vs GeForce GTX 870M

Intro

The GeForce GTX 295 uses a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this model. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

Compare that to the GeForce GTX 870M, which has core speeds of 941 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 870M 110 Watts
GeForce GTX 295 289 Watts
Difference: 179 Watts (163%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 should be 133% quicker than the GeForce GTX 870M overall, because of its greater data rate. (explain)

GeForce GTX 295 223776 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 127776 (133%)

Texel Rate

The GeForce GTX 870M is a bit (about 14%) better at AF than the GeForce GTX 295. (explain)

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

Pixel Rate

The GeForce GTX 295 is quite a bit (approximately 43%) more effective at AA than the GeForce GTX 870M, and should be able to handle higher screen resolutions better. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the 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 card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
