GeForce GTX 560 Ti 448 vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti 448 should be quite a bit faster than the Radeon R7 M260X overall. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 80000 (125%)

Texel Rate

The GeForce GTX 560 Ti 448 should be quite a bit (about 107%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 21192 (107%)

Pixel Rate

The GeForce GTX 560 Ti 448 will be much (about 344%) better at full screen anti-aliasing than the Radeon R7 M260X, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 22680 (344%)

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 max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the 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 the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
