Radeon R7 370 4G vs Radeon R9 380X

Intro

The Radeon R7 370 4G comes with clock speeds of 975 MHz on the GPU, and 1400 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Compare those specs to the Radeon R9 380X, which makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM is set to run at a speed of 1425 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
