GeForce GTX 970 vs Radeon HD 4870 X2

Intro

The GeForce GTX 970 has a core clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It features 1664 SPUs, 104 TAUs, and 64 Raster Operation Units.

Compare those specs to the Radeon HD 4870 X2, which features a core clock frequency of 750 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce GTX 970 109200 Mtexels/sec
Radeon HD 4870 X2 60000 Mtexels/sec
Difference: 49200 (82%)

Pixel Rate

The GeForce GTX 970 will be much (approximately 180%) better at FSAA than the Radeon HD 4870 X2, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 970 67200 Mpixels/sec
Radeon HD 4870 X2 24000 Mpixels/sec
Difference: 43200 (180%)

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 information (measured in MB per second) that can be moved over 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 it uses DDR RAM, it must be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
