Radeon HD 4670 512MB vs Radeon R7 240

Intro

The Radeon HD 4670 512MB has a GPU core clock speed of 750 MHz, and the 512 MB of GDDR4/GDDR3/DDR3/DDR2 RAM runs at 1000 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 32 TAUs, and 8 ROPs.

Compare all of that to the Radeon R7 240, which features GPU clock speed of 730 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is comprised of 320 SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should 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 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 is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
