Compare any two graphics cards:
Radeon R9 M380 vs Radeon RX 460
IntroThe Radeon R9 M380 uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.
Compare those specifications to the Radeon RX 460, which comes with GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
The Radeon RX 460 should in theory perform a little bit faster than the Radeon R9 M380 overall. (explain)
Texel RateThe Radeon RX 460 is quite a bit (approximately 53%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)
Pixel RateThe Radeon RX 460 will be just a bit (more or less 9%) better at full screen anti-aliasing than the Radeon R9 M380, and should be able to handle 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of 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 most pixels the graphics card could 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
