GeForce 8600 GTS vs Radeon R9 M375

Intro

The GeForce 8600 GTS uses a 80 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR3 RAM runs at a speed of 1000 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare all of that to the Radeon R9 M375, which features a clock speed of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375 should theoretically be just a bit faster than the GeForce 8600 GTS overall. (explain)

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

Texel Rate

The Radeon R9 M375 should be much (about 276%) better at anisotropic filtering 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 screen resolution is important to you, then the Radeon R9 M375 is a better choice, by far. (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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
