GeForce GTX 480 vs Radeon R7 370 4G

Intro

Compare all 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 made up of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

Radeon R7 370 4G		110 Watts
GeForce GTX 480		250 Watts
	Difference: 140 Watts (127%)

Memory Bandwidth

In theory, the Radeon R7 370 4G should perform a little bit faster than the GeForce GTX 480 in general. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GTX 480		177408 MB/sec
	Difference: 1792 (1%)

Texel Rate

The Radeon R7 370 4G should be quite a bit (approximately 49%) more effective at anisotropic filtering than the GeForce GTX 480. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 20400 (49%)

Pixel Rate

The GeForce GTX 480 is just a bit (about 8%) more effective at anti-aliasing than the Radeon R7 370 4G, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R7 370 4G		31200 Mpixels/sec
	Difference: 2400 (8%)

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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
