Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon R7 260X
IntroThe Radeon HD 3850 X2 features a GPU core clock speed of 668 MHz, and the 512 MB of GDDR3 RAM runs at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon R7 260X, which features core clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3850 X2 should theoretically be a small bit superior to the Radeon R7 260X overall. (explain)
Texel RateThe Radeon R7 260X is much (about 188%) better at texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon HD 3850 X2 will be quite a bit (approximately 21%) better at anti-aliasing than the Radeon R7 260X, and also should be capable of handling higher resolutions better. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
