Compare any two graphics cards:
GeForce GTX 275 vs Radeon RX 460
IntroThe GeForce GTX 275 makes use of a 55 nm design. nVidia has set the core speed at 633 MHz. The GDDR3 RAM runs at a speed of 1134 MHz on this particular card. It features 240 SPUs as well as 80 Texture Address Units and 28 ROPs.
Compare all that to the Radeon RX 460, which uses a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular model. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 275 should theoretically be a little bit superior to the Radeon RX 460 overall. (explain)
Texel RateThe Radeon RX 460 is a lot (more or less 21%) more effective at anisotropic filtering than the GeForce GTX 275. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 275 is superior to the Radeon RX 460, not by a very large margin though. (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 data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
