GeForce GTX 660 Ti vs Radeon R7 370 4G

Intro

Compare all of that to the Radeon R7 370 4G, which comes with GPU clock speed of 975 MHz, and 4096 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is comprised of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

	Difference: 35200 (24%)

Texel Rate

The GeForce GTX 660 Ti will be a lot (more or less 64%) better at texture filtering than the Radeon R7 370 4G. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 40080 (64%)

Pixel Rate

The Radeon R7 370 4G will be a lot (more or less 42%) better at full screen anti-aliasing than the GeForce GTX 660 Ti, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 9240 (42%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
