Compare any two graphics cards:
Radeon R9 290X vs Radeon RX 5600
IntroThe Radeon R9 290X has a GPU clock speed of 800 MHz, and the 4096 MB of GDDR5 memory runs at 1250 MHz through a 512-bit bus. It also features 2816 SPUs, 176 TAUs, and 64 Raster Operation Units.
Compare all that to the Radeon RX 5600, which features GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 12000 MHz through a 192-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 64 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon R9 290X should in theory perform a bit faster than the Radeon RX 5600 overall. (explain)
Texel RateThe Radeon RX 5600 should be much (more or less 25%) more effective at texture filtering than the Radeon R9 290X. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 5600 is a better choice, and very much so. (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 information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends 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 max fill rate.
