GeForce GTX 260 Core 216 vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which features a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 Core 216 should be much faster than the Radeon R9 M375X overall. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 39888 (55%)

Texel Rate

The GeForce GTX 260 Core 216 should be a little bit (more or less 2%) better at texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 260 Core 216		41472 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 872 (2%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M375X is superior to the GeForce GTX 260 Core 216, not by a very large margin though. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 112 (1%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
