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 clocked the core speed at 1015 MHz. The DDR3 RAM runs at a speed of 1100 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 480 should in theory be much superior to the Radeon R9 M375 overall. (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 (about 3%) faster with regards to anisotropic filtering than the Radeon R9 M375. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 480 is a better choice, by far. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
