Radeon HD 5570 vs Radeon HD 6570 (OEM) 2GB

Intro

The Radeon HD 5570 has a core clock speed of 650 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 400(80x5) SPUs, 20 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the Radeon HD 6570 (OEM) 2GB, which has a core clock frequency of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
