GeForce GTX 480 vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which features GPU core speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 480 should theoretically be quite a bit faster than the Radeon R9 M365X in general. (explain)

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

Texel Rate

The GeForce GTX 480 will be a small bit (about 14%) faster with regards to anisotropic filtering than the Radeon R9 M365X. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is superior to the Radeon R9 M365X, and very much so. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 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 calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
