Compare any two graphics cards:
Radeon HD 3870 512MB vs Radeon R7 260X
IntroThe Radeon HD 3870 512MB comes with a GPU clock speed of 775 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the Radeon R7 260X, which uses a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM is set to run at a speed of 1625 MHz on this specific model. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R7 260X is 81% faster than the Radeon HD 3870 512MB overall, due to its higher data rate. (explain)
Texel RateThe Radeon R7 260X will be much (more or less 397%) faster with regards to texture filtering than the Radeon HD 3870 512MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R7 260X is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
