GeForce 8800 GT 512MB vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which features a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375X should be much faster than the GeForce 8800 GT 512MB overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X is a lot (more or less 21%) faster with regards to AF than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375X will be quite a bit (about 69%) more effective at anti-aliasing than the GeForce 8800 GT 512MB, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 6640 (69%)

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 max amount of information (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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