GeForce GTX 260 vs GeForce GTX 870M

Intro

The GeForce GTX 260 uses a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this card. It features 192 SPUs along with 64 Texture Address Units and 28 Rasterization Operator Units.

Compare those specs to the GeForce GTX 870M, which comes with 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 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 870M 110 Watts
GeForce GTX 260 182 Watts
Difference: 72 Watts (65%)

Memory Bandwidth

The GeForce GTX 260 should in theory be a small bit faster than the GeForce GTX 870M in general. (explain)

GeForce GTX 260 111888 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 15888 (17%)

Texel Rate

The GeForce GTX 870M will be a lot (about 186%) faster with regards to AF than the GeForce GTX 260. (explain)

GeForce GTX 870M 105392 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 68528 (186%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 870M is a better choice, by far. (explain)

GeForce GTX 870M 22584 Mpixels/sec
GeForce GTX 260 16128 Mpixels/sec
Difference: 6456 (40%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses 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 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 better this number, the better the video card will be at handling 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 the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
