Compare any two graphics cards:
Radeon RX 5700 vs Radeon RX Vega 56
IntroThe Radeon RX 5700 has a GPU core clock speed of 1465 MHz, and the 8096 MB of GDDR6 RAM runs at 14000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 TAUs, and 64 ROPs.
Compare all of that to the Radeon RX Vega 56, which comes with core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs along with 224 TAUs and 64 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 5700 should in theory be just a bit better than the Radeon RX Vega 56 overall. (explain)
Texel RateThe Radeon RX Vega 56 will be quite a bit (about 23%) better at AF than the Radeon RX 5700. (explain)
Pixel RateThe Radeon RX 5700 is much (approximately 27%) faster with regards to AA than the Radeon RX Vega 56, and should be capable of handling higher resolutions without losing too much performance. (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 (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
