Compare any two graphics cards:
Radeon HD 7750 vs Radeon RX 590
IntroThe Radeon HD 7750 has clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.
Compare those specifications to the Radeon RX 590, which makes use of a 12 nm design. AMD has set the core speed at 1469 MHz. The GDDR5 memory works at a speed of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 590 should in theory perform a lot faster than the Radeon HD 7750 overall. (explain)
Texel RateThe Radeon RX 590 is much (about 726%) more effective at texture filtering than the Radeon HD 7750. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon RX 590 is superior to the Radeon HD 7750, 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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
