GeForce GTX 460 vs Radeon R9 M365X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 460 is 20% quicker than the Radeon R9 M365X overall, because of its greater data rate. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 460 will be a little bit (about 2%) better at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 800 (2%)

Pixel Rate

The GeForce GTX 460 should be a bit (approximately 9%) faster with regards to anti-aliasing than the Radeon R9 M365X, and should be able to handle higher resolutions better. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 1400 (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: Memory bandwidth is the max amount of information (measured in MB 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. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at 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 that the graphics chip could possibly write to the local memory in a 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 speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
