GeForce GTX 460 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 460 will be 20% faster than the Radeon R9 M365X in general, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 460 is a little bit (approximately 2%) faster with regards to 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 will be just a bit (more or less 9%) better at anti-aliasing than the Radeon R9 M365X, and also should be able to handle higher screen resolutions more effectively. (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 transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
