Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon R9 M365X
IntroThe GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 memory works at a speed of 700 MHz on this card. It features 32 SPUs along with 16 TAUs and 8 ROPs.
Compare those specs to the Radeon R9 M365X, which comes with a clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
As far as performance goes, the Radeon R9 M365X should theoretically be quite a bit better than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe Radeon R9 M365X is quite a bit (approximately 328%) more effective at AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, by a large margin. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
