Compare any two graphics cards:
Radeon R7 240 vs Radeon R9 270
IntroThe Radeon R7 240 has a clock speed of 730 MHz and a DDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 320 SPUs, 20 TAUs, and 8 ROPs.Compare all of that to the Radeon R9 270, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory works at a speed of 1400 MHz on this specific card. It features 1280 SPUs along with 80 TAUs and 32 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 270 is 522% quicker than the Radeon R7 240 overall, due to its higher data rate. (explain)
Texel RateThe Radeon R9 270 should be much (about 393%) more effective at anisotropic filtering than the Radeon R7 240. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 270 is superior to the Radeon R7 240, 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 data (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
