GeForce 8800 GS vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 memory works at a frequency of 1100 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 8800 GS should perform just a bit faster than the Radeon R9 M375 in general. (explain)

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

Texel Rate

The Radeon R9 M375 will be much (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 running with a high resolution is important to you, then the Radeon R9 M375 is superior to the GeForce 8800 GS, by a large margin. (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
