GeForce 8600 GTS vs Radeon R9 M365X

Intro

The GeForce 8600 GTS comes with 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 comprised of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare that to the Radeon R9 M365X, which features a clock speed of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M365X should in theory be much superior to the GeForce 8600 GTS overall. (explain)

Radeon R9 M365X 72000 MB/sec
GeForce 8600 GTS 32000 MB/sec
Difference: 40000 (125%)

Texel Rate

The Radeon R9 M365X will be a lot (about 243%) more effective at texture filtering than the GeForce 8600 GTS. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 26200 (243%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M365X is a better choice, by a large margin. (explain)

Radeon R9 M365X 14800 Mpixels/sec
GeForce 8600 GTS 5400 Mpixels/sec
Difference: 9400 (174%)

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 data (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per 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 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 maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
