GeForce GTX 650 vs Radeon R9 M370X

Intro

Compare that to the Radeon R9 M370X, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 650 should in theory be just a bit superior to the Radeon R9 M370X in general. (explain)

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

Texel Rate

The GeForce GTX 650 should be a little bit (approximately 6%) more effective at anisotropic 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 high levels of AA is important to you, then the GeForce GTX 650 is the winner, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of 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.
