Compare any two graphics cards:
Radeon R7 370 2G vs Radeon RX 470
IntroThe Radeon R7 370 2G makes use of a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 memory is set to run at a frequency of 1400 MHz on this specific card. It features 1024 SPUs as well as 64 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 specific model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 470 should in theory be just a bit superior to the Radeon R7 370 2G in general. (explain)
Texel RateThe Radeon RX 470 will be much (approximately 90%) faster with regards to texture filtering than the Radeon R7 370 2G. (explain)
Pixel RateThe Radeon R7 370 2G should be just a bit (approximately 5%) more effective at anti-aliasing than the Radeon RX 470, and should be capable of handling higher resolutions while still performing well. (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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
