GeForce GTX 260 vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 260 should perform quite a bit faster than the Radeon R9 M365X in general. (explain)

GeForce GTX 260		111888 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 39888 (55%)

Texel Rate

The Radeon R9 M365X should be a bit (more or less 0%) better at anisotropic filtering than the GeForce GTX 260. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 136 (0%)

Pixel Rate

The GeForce GTX 260 should be a small bit (about 9%) more effective at anti-aliasing than the Radeon R9 M365X, and also able to handle higher screen resolutions better. (explain)

GeForce GTX 260		16128 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 1328 (9%)

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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
