Compare any two graphics cards:
Radeon R9 M295X vs Radeon RX 470 4GB
IntroThe Radeon R9 M295X features core clock speeds of 750 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.
Compare those specifications to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has clocked the core frequency at 926 MHz. The GDDR5 RAM works at a frequency of 1650 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 470 4GB should in theory be a little bit superior to the Radeon R9 M295X in general. (explain)
Texel RateThe Radeon RX 470 4GB will be a lot (about 23%) better at texture filtering than the Radeon R9 M295X. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon RX 470 4GB is superior to the Radeon R9 M295X, by far. (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 data (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
