GeForce GTX 560 vs Radeon HD 4870 1GB

Intro

The GeForce GTX 560 uses a 40 nm design. nVidia has set the core frequency at 810 MHz. The GDDR5 memory works at a speed of 1001 MHz on this particular model. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon HD 4870 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM works at a frequency of 900 MHz on this specific model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce GTX 560 should perform a bit faster than the Radeon HD 4870 1GB in general. (explain)

GeForce GTX 560 128128 MB/sec
Radeon HD 4870 1GB 115200 MB/sec
Difference: 12928 (11%)

Texel Rate

The GeForce GTX 560 will be much (more or less 51%) faster with regards to AF than the Radeon HD 4870 1GB. (explain)

GeForce GTX 560 45360 Mtexels/sec
Radeon HD 4870 1GB 30000 Mtexels/sec
Difference: 15360 (51%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is a better choice, and very much so. (explain)

GeForce GTX 560 25920 Mpixels/sec
Radeon HD 4870 1GB 12000 Mpixels/sec
Difference: 13920 (116%)

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 information (measured in MB per second) that can be moved 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 it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant 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.
