GeForce GTX 660 Ti vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which has GPU clock speed of 800 MHz, and 2048 MB of GDDR5 RAM set to run 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

In theory, the GeForce GTX 660 Ti will be 100% quicker than the Radeon R9 M370X overall, because of its higher data rate. (explain)

GeForce GTX 660 Ti		144000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 72000 (100%)

Texel Rate

The GeForce GTX 660 Ti will be a lot (approximately 220%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 70480 (220%)

Pixel Rate

The GeForce GTX 660 Ti will be quite a bit (more or less 72%) better at anti-aliasing than the Radeon R9 M370X, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 9160 (72%)

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 information (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends 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 max fill rate.
