Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon R9 380X
IntroThe Radeon HD 7870 XT makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this specific card. It features 1536 SPUs as well as 96 TAUs and 32 ROPs.
Compare all of that to the Radeon R9 380X, which has a core clock speed of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon HD 7870 XT should be a bit faster than the Radeon R9 380X overall. (explain)
Texel RateThe Radeon R9 380X is quite a bit (about 40%) better at anisotropic filtering than the Radeon HD 7870 XT. (explain)
Pixel RateThe Radeon R9 380X should be just a bit (about 5%) more effective at FSAA than the Radeon HD 7870 XT, and also should 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.
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 MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
