Compare any two graphics cards:
GeForce GTX 970M vs Radeon RX 460
IntroThe GeForce GTX 970M comes with core speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs along with 80 TAUs and 48 Rasterization Operator Units.
Compare all that to the Radeon RX 460, which has clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Performance-wise, the Radeon RX 460 should in theory be a small bit better than the GeForce GTX 970M overall. (explain)
Texel RateThe GeForce GTX 970M is a lot (about 21%) faster with regards to AF than the Radeon RX 460. (explain)
Pixel RateThe GeForce GTX 970M is quite a bit (more or less 154%) better at anti-aliasing than the Radeon RX 460, and also should be capable of handling higher screen resolutions while still performing well. (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 moved across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
