GeForce 8600 GTS vs Radeon R9 M375

Intro

The GeForce 8600 GTS has a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all of that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 memory is set to run at a speed 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

In theory, the Radeon R9 M375 is 10% quicker than the GeForce 8600 GTS overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R9 M375 is a lot (more or less 276%) better at AF than the GeForce 8600 GTS. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375 is a better choice, by a large margin. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
