GeForce GTX 480 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 480 is 146% quicker than the Radeon R9 M365X in general, due to its higher data rate. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 105408 (146%)

Texel Rate

The GeForce GTX 480 should be a little bit (approximately 14%) better at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 5000 (14%)

Pixel Rate

The GeForce GTX 480 will be quite a bit (more or less 127%) better at FSAA than the Radeon R9 M365X, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 18800 (127%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
