Compare any two graphics cards:
Radeon R7 370 4G vs Radeon RX 470
IntroThe Radeon R7 370 4G features a GPU clock speed of 975 MHz, and the 4096 MB of GDDR5 memory runs at 1400 MHz through a 256-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 32 ROPs.
Compare those specs to the Radeon RX 470, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory works at a frequency of 1650 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 470, in theory, should perform a small bit faster than the Radeon R7 370 4G overall. (explain)
Texel RateThe Radeon RX 470 will be a lot (approximately 90%) more effective at anisotropic filtering than the Radeon R7 370 4G. (explain)
Pixel RateThe Radeon R7 370 4G is a bit (approximately 5%) faster with regards to full screen anti-aliasing than the Radeon RX 470, and will be capable of handling higher 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 information (counted in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video 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 card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
