GeForce 8800 GS vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 memory works at a speed of 1100 MHz on this specific 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 in theory be a little bit superior to 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 a lot (more or less 54%) faster with regards to anisotropic filtering than the GeForce 8800 GS. (explain)

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

Pixel Rate

The Radeon R9 M375 will be quite a bit (about 146%) more effective at anti-aliasing than the GeForce 8800 GS, and will be able to handle higher resolutions more effectively. (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 largest 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 card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
