GeForce 8600 GTS vs Radeon R9 M375

Intro

The GeForce 8600 GTS makes use of a 80 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR3 memory runs at a frequency of 1000 MHz on this particular card. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare those specifications to the Radeon R9 M375, which has a clock speed of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375 should theoretically be just a bit superior to the GeForce 8600 GTS in general. (explain)

Radeon R9 M375 35200 MB/sec
GeForce 8600 GTS 32000 MB/sec
Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 is quite a bit (approximately 276%) faster with regards to AF than the GeForce 8600 GTS. (explain)

Radeon R9 M375 40600 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 29800 (276%)

Pixel Rate

The Radeon R9 M375 will be a lot (more or less 201%) more effective at anti-aliasing than the GeForce 8600 GTS, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M375 16240 Mpixels/sec
GeForce 8600 GTS 5400 Mpixels/sec
Difference: 10840 (201%)

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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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