Radeon R7 370 2G vs Radeon RX 470 4GB

Intro

The Radeon R7 370 2G comes with a core clock frequency of 975 MHz and a GDDR5 memory frequency of 1400 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Compare all of that to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM runs at a frequency of 1650 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 worked out by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
