GeForce GTX 650 vs Radeon R9 M370X

Intro

The GeForce GTX 650 has core speeds of 1058 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Compare that to the Radeon R9 M370X, which has a clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 is 11% quicker than the Radeon R9 M370X overall, due to its higher bandwidth. (explain)

GeForce GTX 650 80000 MB/sec
Radeon R9 M370X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The GeForce GTX 650 is just a bit (approximately 6%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

GeForce GTX 650 33856 Mtexels/sec
Radeon R9 M370X 32000 Mtexels/sec
Difference: 1856 (6%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 is the winner, by a large margin. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R9 M370X 12800 Mpixels/sec
Difference: 4128 (32%)

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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
