Compare any two graphics cards:
Geforce GTX 760 vs Radeon R9 270
IntroThe Geforce GTX 760 uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this specific card. It features 1152 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.
Compare all that to the Radeon R9 270, which uses a 28 nm design. ATi has clocked the core frequency at 900 MHz. The GDDR5 memory is set to run at a frequency of 1400 MHz on this card. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 760 should be just a bit faster than the Radeon R9 270 overall. (explain)
Texel RateThe Geforce GTX 760 should be much (about 31%) better at texture filtering than the Radeon R9 270. (explain)
Pixel RateThe Geforce GTX 760 will be a little bit (about 9%) more effective at AA than the Radeon R9 270, and also should 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
