Compare any two graphics cards:
GeForce GTX 660 vs Radeon R9 270X
IntroThe GeForce GTX 660 has a clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 192-bit memory bus, and makes use of a 28 nm design. It features 960 SPUs, 80 TAUs, and 24 ROPs.Compare all that to the Radeon R9 270X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1400 MHz on this model. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 270X will be 24% quicker than the GeForce GTX 660 overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 270X will be a small bit (about 2%) more effective at AF than the GeForce GTX 660. (explain)
Pixel RateThe Radeon R9 270X should be much (more or less 36%) better at FSAA than the GeForce GTX 660, and will be capable of handling higher resolutions without losing too much performance. (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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses 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 are processed in one second. This figure is calculated by multiplying the total amount of texture units 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 in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
