GeForce GTX 560 Ti 448 vs Radeon HD 5870

Intro

The GeForce GTX 560 Ti 448 features a GPU core clock speed of 732 MHz, and the 1280 MB of GDDR5 memory runs at 900 MHz through a 320-bit bus. It also is comprised of 448 Stream Processors, 56 Texture Address Units, and 40 ROPs.

Compare all that to the Radeon HD 5870, which features GPU clock speed of 850 MHz, and 1024 MB of GDDR5 RAM running at 1200 MHz through a 256-bit bus. It also is made up of 1600(320x5) SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Consumption (Max TDP)

Radeon HD 5870 188 Watts
GeForce GTX 560 Ti 448 210 Watts
Difference: 22 Watts (12%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5870 should perform a small bit faster than the GeForce GTX 560 Ti 448 in general. (explain)

Radeon HD 5870 153600 MB/sec
GeForce GTX 560 Ti 448 144000 MB/sec
Difference: 9600 (7%)

Texel Rate

The Radeon HD 5870 should be much (more or less 66%) more effective at AF than the GeForce GTX 560 Ti 448. (explain)

Radeon HD 5870 68000 Mtexels/sec
GeForce GTX 560 Ti 448 40992 Mtexels/sec
Difference: 27008 (66%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon HD 5870, though not by far. (explain)

GeForce GTX 560 Ti 448 29280 Mpixels/sec
Radeon HD 5870 27200 Mpixels/sec
Difference: 2080 (8%)

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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
