Compare any two graphics cards:
Radeon HD 6950 vs Radeon R9 M270X
IntroThe Radeon HD 6950 features a core clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 6950 should theoretically be quite a bit better than the Radeon R9 M270X overall. (explain)
Texel RateThe Radeon HD 6950 should be much (more or less 143%) faster with regards to AF than the Radeon R9 M270X. (explain)
Pixel RateThe Radeon HD 6950 is quite a bit (more or less 121%) better at AA than the Radeon R9 M270X, and also will be able to handle higher resolutions while still performing well. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
