GeForce GTX 480 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 RAM runs at a frequency of 1100 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 will be 404% faster than the Radeon R9 M375 in general, because of its higher data rate. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 142208 (404%)

Texel Rate

The GeForce GTX 480 should be a small bit (more or less 3%) more effective at AF than the Radeon R9 M375. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 1400 (3%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 480 is the winner, by a large margin. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 17360 (107%)

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 data (counted in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
