Compare any two graphics cards:
Radeon R9 M295X vs Radeon RX 470
IntroThe Radeon R9 M295X uses a 28 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM works at a frequency of 1375 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.
Compare that to the Radeon RX 470, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory is set to run at a frequency of 1650 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470 should in theory be a little bit faster than the Radeon R9 M295X in general. (explain)
Texel RateThe Radeon RX 470 will be much (more or less 23%) faster with regards to texture filtering than the Radeon R9 M295X. (explain)
Pixel RateThe Radeon RX 470 should be a lot (about 23%) better at FSAA than the Radeon R9 M295X, and will 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 largest amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
