GeForce GTX 260 Core 216 vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 260 Core 216 will be 55% faster than the Radeon R9 M370X overall, due to its greater bandwidth. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 39888 (55%)

Texel Rate

The GeForce GTX 260 Core 216 should be much (about 30%) better at AF than the Radeon R9 M370X. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 9472 (30%)

Pixel Rate

The GeForce GTX 260 Core 216 will be a lot (about 26%) more effective at full screen anti-aliasing than the Radeon R9 M370X, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 3328 (26%)

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 max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
