GeForce 8600 GT 1GB GDDR3 vs Radeon RX 5700

Intro

The GeForce 8600 GT 1GB GDDR3 comes with core clock speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Compare all that to the Radeon RX 5700, which uses a 7 nm design. AMD has clocked the core speed at 1465 MHz. The GDDR6 memory is set to run at a frequency of 1750 MHz on this specific model. It features 2304 SPUs as well as 144 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3 47 Watts
Radeon RX 5700 180 Watts
Difference: 133 Watts (283%)

Memory Bandwidth

In theory, the Radeon RX 5700 should be 1948% quicker than the GeForce 8600 GT 1GB GDDR3 overall, due to its greater data rate. (explain)

Radeon RX 5700 458752 MB/sec
GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 436352 (1948%)

Texel Rate

The Radeon RX 5700 will be quite a bit (about 2342%) better at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

Radeon RX 5700 210960 Mtexels/sec
GeForce 8600 GT 1GB GDDR3 8640 Mtexels/sec
Difference: 202320 (2342%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5700 is the winner, by far. (explain)

Radeon RX 5700 93760 Mpixels/sec
GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Difference: 89440 (2070%)

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 data (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed in one second. This 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 card will be at 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 that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 ability to reach the maximum fill rate.
