GeForce GTX 260 216SP 55 nm vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 260 216SP 55 nm should perform quite a bit faster than the Radeon R9 M370X overall. (explain)

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

Texel Rate

The GeForce GTX 260 216SP 55 nm will be a lot (more or less 30%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 9472 (30%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 260 216SP 55 nm is a better choice, and very much so. (explain)

GeForce GTX 260 216SP 55 nm		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 data (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
