Compare any two graphics cards:
Geforce GTX 760 vs Radeon R9 270
IntroThe Geforce GTX 760 comes with a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Radeon R9 270, which uses a 28 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1400 MHz on this model. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760 should in theory be a bit faster than the Radeon R9 270 in general. (explain)
Texel RateThe Geforce GTX 760 will be much (more or less 31%) more effective at texture filtering than the Radeon R9 270. (explain)
Pixel RateThe Geforce GTX 760 is a small bit (approximately 9%) faster with regards to anti-aliasing than the Radeon R9 270, and capable of handling higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
