Compare any two graphics cards:
Radeon HD 5850 vs Radeon R9 270
IntroThe Radeon HD 5850 makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular card. It features 1440(288x5) SPUs along with 72 Texture Address Units and 32 Rasterization Operator Units.Compare those specs to the Radeon R9 270, which features core speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 RAM. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 270, in theory, should perform a lot faster than the Radeon HD 5850 overall. (explain)
Texel RateThe Radeon R9 270 is a lot (more or less 38%) better at AF than the Radeon HD 5850. (explain)
Pixel RateThe Radeon R9 270 will be quite a bit (approximately 24%) faster with regards to anti-aliasing than the Radeon HD 5850, and should be capable of handling higher resolutions more effectively. (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 data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once 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 high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
