Compare any two graphics cards:
Radeon R9 M295X vs Radeon RX 470
IntroThe Radeon R9 M295X uses a 28 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory runs at a speed of 1375 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.
Compare that to the Radeon RX 470, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 RAM is set to run at a speed of 1650 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 470 should theoretically be a little bit superior to the Radeon R9 M295X overall. (explain)
Texel RateThe Radeon RX 470 will be a lot (about 23%) more effective at texture filtering than the Radeon R9 M295X. (explain)
Pixel RateThe Radeon RX 470 is quite a bit (more or less 23%) better at AA than the Radeon R9 M295X, and also will be capable of handling higher screen resolutions without slowing down too much. (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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one 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 this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
