Compare any two graphics cards:
Radeon R9 290 vs Radeon RX 6700 XT
IntroThe Radeon R9 290 makes use of 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 model. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.Compare all that to the Radeon RX 6700 XT, which has a GPU core clock speed of 2321 MHz, and (Unknown) MB of GDDR6 RAM set to run at 2000 MHz through a 192-bit bus. It also is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon RX 6700 XT is 23% faster than the Radeon R9 290 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 6700 XT is a lot (more or less 190%) faster with regards to AF than the Radeon R9 290. (explain)
Pixel RateThe Radeon RX 6700 XT is quite a bit (about 190%) better at AA than the Radeon R9 290, and will be able to handle 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock 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 card's memory bandwidth, 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 can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
