GeForce GTX 285 2GB vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which comes with a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon R9 M365X		72000 MB/sec
	Difference: 86976 (121%)

Texel Rate

The GeForce GTX 285 2GB is a lot (more or less 40%) more effective at anisotropic filtering than the Radeon R9 M365X. (explain)

GeForce GTX 285 2GB		51840 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 14840 (40%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 285 2GB is superior to the Radeon R9 M365X, by far. (explain)

GeForce GTX 285 2GB		20736 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 5936 (40%)

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 information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 amount of pixels the graphics card can possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
