Compare any two graphics cards:
Radeon HD 6970 vs Radeon R9 M295X
IntroThe Radeon HD 6970 features a clock frequency of 880 MHz and a GDDR5 memory speed of 1375 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is comprised of 1536 SPUs, 96 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R9 M295X, which comes with a clock frequency of 750 MHz and a GDDR5 memory frequency of 1375 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon R9 M295X will be a small bit (about 14%) faster with regards to anisotropic filtering than the Radeon HD 6970. (explain)
Pixel RateThe Radeon HD 6970 will be a bit (approximately 17%) more effective at anti-aliasing than the Radeon R9 M295X, and capable of handling higher screen 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. Price Comparison

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total 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 in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
