Compare any two graphics cards:
Geforce GTX 760 vs Radeon R9 270
IntroThe Geforce GTX 760 makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this particular card. It features 1152 SPUs along with 96 TAUs and 32 Rasterization Operator Units.
Compare those specs to the Radeon R9 270, which features GPU core speed of 900 MHz, and 2048 MB of GDDR5 RAM set to run at 1400 MHz through a 256-bit bus. It also features 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 760 should in theory be a little bit superior to the Radeon R9 270 overall. (explain)
Texel RateThe Geforce GTX 760 is quite a bit (about 31%) better at anisotropic filtering than the Radeon R9 270. (explain)
Pixel RateIf using a high resolution is important to you, then the Geforce GTX 760 is the winner, though not by far. (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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better 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 most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
