GeForce GTX 560 Ti 448 vs Radeon R9 M270X

Intro

Compare that to the Radeon R9 M270X, which uses a 28 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Radeon R9 M270X		29000 Mtexels/sec
	Difference: 11992 (41%)

Pixel Rate

The GeForce GTX 560 Ti 448 is quite a bit (more or less 152%) better at AA than the Radeon R9 M270X, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 17680 (152%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
