GeForce 8800 GS vs Radeon R9 M375

Intro

Compare all 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 card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 8800 GS should theoretically be a small bit better than the Radeon R9 M375 overall. (explain)

GeForce 8800 GS		38400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 3200 (9%)

Texel Rate

The Radeon R9 M375 should be quite a bit (approximately 54%) more effective at AF than the GeForce 8800 GS. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 14200 (54%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375 is the winner, by far. (explain)

Radeon R9 M375		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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 ability to get to the max fill rate.
