Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon R9 M390X
IntroThe GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 memory is set to run at a frequency of 700 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all of that to the Radeon R9 M390X, which comes with clock speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M390X should theoretically be much faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe Radeon R9 M390X is quite a bit (more or less 971%) faster with regards to texture filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M390X is superior to the GeForce 8600 GT 256MB GDDR3, by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock 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 processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
