Compare any two graphics cards:
Radeon HD 6750 vs Radeon R9 M365X
IntroThe Radeon HD 6750 has a GPU core clock speed of 725 MHz, and the 512 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 720 SPUs, 36 TAUs, and 16 ROPs.
Compare those specifications to the Radeon R9 M365X, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.
Power Usage and Theoretical Benchmarks
The Radeon R9 M365X, in theory, should perform a small bit faster than the Radeon HD 6750 overall. (explain)
Texel RateThe Radeon R9 M365X is quite a bit (more or less 42%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, 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.
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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the 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 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
