Compare any two graphics cards:
Geforce GTX 760 vs Radeon R9 270
IntroThe Geforce GTX 760 has a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.
Compare those specs to the Radeon R9 270, which uses a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a speed of 1400 MHz on this specific model. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 760 will be 7% faster than the Radeon R9 270 overall, due to its higher bandwidth. (explain)
Texel RateThe Geforce GTX 760 will be a lot (more or less 31%) better at anisotropic filtering than the Radeon R9 270. (explain)
Pixel RateThe Geforce GTX 760 should be a small bit (more or less 9%) faster with regards to full screen anti-aliasing than the Radeon R9 270, and will be able to handle 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
