Radeon HD 4350 vs Radeon R9 390 8G

Intro

The Radeon HD 4350 uses a 55 nm design. AMD has clocked the core frequency at 575 MHz. The DDR2 memory is set to run at a speed of 500 MHz on this model. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Compare those specifications to the Radeon R9 390 8G, which has a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
