GeForce GTX 560 vs Radeon HD 5870

Intro

The GeForce GTX 560 has core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Compare all of that to the Radeon HD 5870, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM works at a speed of 1200 MHz on this specific model. It features 1600(320x5) SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 150 Watts
Radeon HD 5870 188 Watts
Difference: 38 Watts (25%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5870 will be 20% quicker than the GeForce GTX 560 overall, because of its greater bandwidth. (explain)

Radeon HD 5870 153600 MB/sec
GeForce GTX 560 128128 MB/sec
Difference: 25472 (20%)

Texel Rate

The Radeon HD 5870 will be much (more or less 50%) faster with regards to anisotropic filtering than the GeForce GTX 560. (explain)

Radeon HD 5870 68000 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 22640 (50%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5870 is a better choice, but only just. (explain)

Radeon HD 5870 27200 Mpixels/sec
GeForce GTX 560 25920 Mpixels/sec
Difference: 1280 (5%)

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 max amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be applied per second. This number is calculated by multiplying the total amount of 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
