Radeon HD 4350 vs Radeon R9 390 8G

Intro

The Radeon HD 4350 has a GPU core clock speed of 575 MHz, and the 512 MB of DDR2 RAM runs at 500 MHz through a 64-bit bus. It also is comprised of 80(16x5) Stream Processors, 8 TAUs, and 4 ROPs.

Compare those specs to the Radeon R9 390 8G, which has GPU core speed of 1000 MHz, and 8192 MB of GDDR5 RAM running at 1500 MHz through a 512-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
