GeForce GTX 560 Ti vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Radeon R9 M265X		23000 Mtexels/sec
	Difference: 29608 (129%)

Pixel Rate

The GeForce GTX 560 Ti should be much (about 186%) more effective at AA than the Radeon R9 M265X, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 17104 (186%)

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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
