Compare any two graphics cards:
GeForce GTX 275 vs Radeon RX 460
IntroThe GeForce GTX 275 has a GPU core speed of 633 MHz, and the 896 MB of GDDR3 memory is set to run at 1134 MHz through a 448-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 28 ROPs.
Compare those specs to the Radeon RX 460, which has GPU core speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 275 should in theory be just a bit better than the Radeon RX 460 in general. (explain)
Texel RateThe Radeon RX 460 will be much (about 21%) faster with regards to anisotropic filtering than the GeForce GTX 275. (explain)
Pixel RateThe GeForce GTX 275 should be a bit (about 2%) more effective at full screen anti-aliasing than the Radeon RX 460, and will be capable of handling higher screen 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.
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 moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
