Compare any two graphics cards:
Radeon HD 7850 vs Radeon R7 260X
IntroThe Radeon HD 7850 makes use of a 28 nm design. AMD has clocked the core speed at 860 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this specific model. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.
Compare those specifications to the Radeon R7 260X, which features clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7850 should theoretically be a lot faster than the Radeon R7 260X in general. (explain)
Texel RateThe Radeon R7 260X is a bit (about 12%) faster with regards to AF than the Radeon HD 7850. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 7850 is superior to the Radeon R7 260X, 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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
