Radeon R7 370 4G vs Radeon RX 470

Intro

The Radeon R7 370 4G makes use of a 28 nm design. AMD has clocked the core speed at 975 MHz. The GDDR5 RAM runs at a frequency of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Compare that to the Radeon RX 470, which features core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
