GeForce 8800 GS vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X is 88% quicker than the GeForce 8800 GS overall, because of its higher bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R9 M375X is quite a bit (about 54%) faster with regards to texture filtering than the GeForce 8800 GS. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 14200 (54%)

Pixel Rate

The Radeon R9 M375X should be quite a bit (more or less 146%) faster with regards to full screen anti-aliasing than the GeForce 8800 GS, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 9640 (146%)

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 (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
