GeForce 8600 GT 256MB GDDR3 vs Radeon R9 M365X

Intro

The GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM works at a speed of 700 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X should be 221% faster than the GeForce 8600 GT 256MB GDDR3 in general, because of its greater bandwidth. (explain)

Radeon R9 M365X 72000 MB/sec
GeForce 8600 GT 256MB GDDR3 22400 MB/sec
Difference: 49600 (221%)

Texel Rate

The Radeon R9 M365X is much (approximately 328%) faster with regards to AF than the GeForce 8600 GT 256MB GDDR3. (explain)

Radeon R9 M365X 37000 Mtexels/sec
GeForce 8600 GT 256MB GDDR3 8640 Mtexels/sec
Difference: 28360 (328%)

Pixel Rate

If using lots of anti-aliasing 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 GT 256MB GDDR3 4320 Mpixels/sec
Difference: 10480 (243%)

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 information (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
