GeForce 8800 GS vs Radeon R9 M375

Intro

The GeForce 8800 GS features a GPU clock speed of 550 MHz, and the 384 MB of GDDR3 memory is set to run at 800 MHz through a 192-bit bus. It also is comprised of 96 SPUs, 48 Texture Address Units, and 12 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GS should be 9% faster than the Radeon R9 M375 in general, due to its higher data rate. (explain)

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

Texel Rate

The Radeon R9 M375 is quite a bit (approximately 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 is a lot (about 146%) more effective at AA than the GeForce 8800 GS, and also should be able to handle higher resolutions while still performing well. (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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
