GeForce GTX 260 Core 216 vs Radeon HD 7870 XT

Intro

The GeForce GTX 260 Core 216 comes with core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.

Compare all that to the Radeon HD 7870 XT, which comes with a core clock speed of 925 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1536 SPUs, 96 TAUs, and 32 ROPs.

Theoretically speaking, the Radeon HD 7870 XT should be 72% faster than the GeForce GTX 260 Core 216 in general, because of its higher bandwidth. (explain)

Radeon HD 7870 XT 192000 MB/sec
GeForce GTX 260 Core 216 111888 MB/sec
Difference: 80112 (72%)

Texel Rate

The Radeon HD 7870 XT should be much (about 114%) faster with regards to texture filtering than the GeForce GTX 260 Core 216. (explain)

Radeon HD 7870 XT 88800 Mtexels/sec
GeForce GTX 260 Core 216 41472 Mtexels/sec
Difference: 47328 (114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 7870 XT is a better choice, by far. (explain)

Radeon HD 7870 XT 29600 Mpixels/sec
GeForce GTX 260 Core 216 16128 Mpixels/sec
Difference: 13472 (84%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock 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 number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
