GeForce 8600 GT 512MB GDDR3 vs Radeon R9 M375

Intro

The GeForce 8600 GT 512MB GDDR3 comes with a GPU clock speed of 540 MHz, and the 512 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 should be 57% quicker than the GeForce 8600 GT 512MB GDDR3 overall, because of its higher data rate. (explain)

Radeon R9 M375 35200 MB/sec
GeForce 8600 GT 512MB GDDR3 22400 MB/sec
Difference: 12800 (57%)

Texel Rate

The Radeon R9 M375 is a lot (about 370%) faster with regards to AF than the GeForce 8600 GT 512MB GDDR3. (explain)

Radeon R9 M375 40600 Mtexels/sec
GeForce 8600 GT 512MB GDDR3 8640 Mtexels/sec
Difference: 31960 (370%)

Pixel Rate

The Radeon R9 M375 will be a lot (more or less 276%) better at AA than the GeForce 8600 GT 512MB GDDR3, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M375 16240 Mpixels/sec
GeForce 8600 GT 512MB GDDR3 4320 Mpixels/sec
Difference: 11920 (276%)

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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
