Compare any two graphics cards:
Radeon RX 470 4GB vs Radeon RX 6600 XT
IntroThe Radeon RX 470 4GB uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory is set to run at a speed of 1650 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.
Compare that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has set the core frequency at 1968 MHz. The GDDR6 RAM works at a frequency of 2000 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon RX 6600 XT should perform much faster than the Radeon RX 470 4GB in general. (explain)
Texel RateThe Radeon RX 6600 XT should be much (approximately 113%) more effective at texture filtering than the Radeon RX 470 4GB. (explain)
Pixel RateThe Radeon RX 6600 XT will be much (more or less 325%) more effective at full screen anti-aliasing than the Radeon RX 470 4GB, and capable of handling higher 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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core clock 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 one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
