Compare any two graphics cards:
Radeon R9 290X vs Radeon RX 6650 XT
IntroThe Radeon R9 290X uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1250 MHz on this particular model. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.
Compare those specifications to the Radeon RX 6650 XT, which comes with a core clock speed of 2055 MHz and a GDDR6 memory frequency of 2190 MHz. It also makes use of a 128-bit memory bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon R9 290X will be 11% faster than the Radeon RX 6650 XT in general, due to its greater data rate. (explain)
Texel RateThe Radeon RX 6650 XT is quite a bit (approximately 87%) better at texture filtering than the Radeon R9 290X. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon RX 6650 XT is superior to the Radeon R9 290X, 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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
