GeForce GTX 650 vs Radeon R9 M365X

Intro

The GeForce GTX 650 comes with a core clock frequency of 1058 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon R9 M365X, which features a clock speed of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 is 11% faster than the Radeon R9 M365X in general, because of its greater bandwidth. (explain)

GeForce GTX 650 80000 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The Radeon R9 M365X will be a bit (more or less 9%) faster with regards to anisotropic filtering than the GeForce GTX 650. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 3144 (9%)

Pixel Rate

The GeForce GTX 650 is just a bit (approximately 14%) faster with regards to full screen anti-aliasing than the Radeon R9 M365X, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 2128 (14%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. The number 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 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
