GeForce GTX 650 Ti vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which features GPU clock speed of 800 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 650 Ti should be 20% quicker than the Radeon R9 M370X overall, because of its higher bandwidth. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti should be much (more or less 86%) more effective at texture filtering than the Radeon R9 M370X. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 27392 (86%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 650 Ti is superior to the Radeon R9 M370X, though only just barely. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 2048 (16%)

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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
