Compare any two graphics cards:
Radeon R9 M385X vs Radeon RX 460
IntroThe Radeon R9 M385X comes with a GPU clock speed of 1100 MHz, and the 4096 MB of GDDR5 memory runs at 1500 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.
Compare those specifications to the Radeon RX 460, which comes with clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Theoretically speaking, the Radeon RX 460 is 17% faster than the Radeon R9 M385X in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon R9 M385X is a small bit (approximately 1%) faster with regards to texture filtering than the Radeon RX 460. (explain)
Pixel RateThe Radeon R9 M385X will be a bit (approximately 1%) more effective at AA than the Radeon RX 460, and also able to handle higher resolutions better. (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 largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core 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 processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
