Compare any two graphics cards:
Radeon HD 6750 vs Radeon R9 M365X
IntroThe Radeon HD 6750 has a GPU core speed of 725 MHz, and the 512 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also features 720 SPUs, 36 TAUs, and 16 ROPs.
Compare all of that to the Radeon R9 M365X, which features a core clock frequency of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
In theory, the Radeon R9 M365X should be 13% quicker than the Radeon HD 6750 overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 M365X is quite a bit (approximately 42%) better at anisotropic filtering than the Radeon HD 6750. (explain)
Pixel RateThe Radeon R9 M365X should be much (more or less 28%) more effective at full screen anti-aliasing than the Radeon HD 6750, and able to handle higher screen resolutions while still performing well. (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 largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
