Compare any two graphics cards:
Radeon HD 6750 1GB vs Radeon R9 M365X
IntroThe Radeon HD 6750 1GB makes use of a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.
Compare those specifications to the Radeon R9 M365X, which comes with a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Theoretically speaking, the Radeon R9 M365X is 13% quicker than the Radeon HD 6750 1GB in general, because of its greater data rate. (explain)
Texel RateThe Radeon R9 M365X should be a lot (approximately 42%) better at texture filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M365X is a better choice, 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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
