Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon RX 480 4GB
IntroThe Radeon HD 7950 3GB comes with core speeds of 800 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 memory. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.
Compare all of that to the Radeon RX 480 4GB, which uses a 14 nm design. AMD has clocked the core speed at 1120 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this model. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 7950 3GB should perform just a bit faster than the Radeon RX 480 4GB overall. (explain)
Texel RateThe Radeon RX 480 4GB should be a lot (approximately 80%) more effective at anisotropic filtering than the Radeon HD 7950 3GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon RX 480 4GB is superior to the Radeon HD 7950 3GB, 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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
