GeForce GTX 560 vs Radeon R9 270

Intro

Compare all that to the Radeon R9 270, which has a core clock speed of 900 MHz and a GDDR5 memory speed of 1400 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon R9 270 should be quite a bit faster than the GeForce GTX 560 overall. (explain)

Radeon R9 270		179200 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 51072 (40%)

Texel Rate

The Radeon R9 270 should be quite a bit (about 59%) better at anisotropic filtering than the GeForce GTX 560. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 26640 (59%)

Pixel Rate

The Radeon R9 270 will be a small bit (more or less 11%) more effective at anti-aliasing than the GeForce GTX 560, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 2880 (11%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
