GeForce GTX 480 vs Radeon R9 M365X

Intro

Compare that to the Radeon R9 M365X, which features GPU clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 480 should be 146% faster than the Radeon R9 M365X overall, 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 will be a bit (more or less 14%) more effective at 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

The GeForce GTX 480 will be a lot (approximately 127%) better at full screen anti-aliasing than the Radeon R9 M365X, and capable of handling higher resolutions while still performing well. (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 largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can 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 colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
