Radeon HD 5770 vs Radeon R9 M375X

Intro

The Radeon HD 5770 uses a 40 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 RAM is set to run at a frequency of 1200 MHz on this card. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
