GeForce GTX 650 vs Radeon R9 M270X

Intro

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

Compare those specs to the Radeon R9 M270X, which has a GPU core clock speed of 725 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 should be a little bit faster than the Radeon R9 M270X in general. (explain)

GeForce GTX 650 80000 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 8000 (11%)

Texel Rate

The GeForce GTX 650 should be a bit (about 17%) faster with regards to AF than the Radeon R9 M270X. (explain)

GeForce GTX 650 33856 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 4856 (17%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 650 is a better choice, and very much so. (explain)

GeForce GTX 650 16928 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 5328 (46%)

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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could 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 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 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 potential to reach the maximum fill rate.
