Radeon R7 370 2G vs Radeon R9 380X

Intro

The Radeon R7 370 2G makes use of a 28 nm design. AMD has clocked the core frequency 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 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the Radeon R9 380X, which comes with GPU clock speed of 970 MHz, and 4096 MB of GDDR5 memory set to run at 1425 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
