GeForce GTX 660 vs Radeon R7 370 4G

Intro

Compare all that to the Radeon R7 370 4G, which comes with a core clock frequency of 975 MHz and a GDDR5 memory speed of 1400 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Texel Rate

The GeForce GTX 660 will be quite a bit (approximately 26%) more effective at AF than the Radeon R7 370 4G. (explain)

GeForce GTX 660		78400 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 16000 (26%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 370 4G is superior to the GeForce GTX 660, and very much so. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 7680 (33%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 potential to get to the maximum fill rate.
