Radeon HD 4850 X2 1GB vs Radeon HD 6570 (OEM) 2GB

Intro

The Radeon HD 4850 X2 1GB features a GPU core speed of 625 MHz, and the 1024 MB of GDDR3 RAM is set to run at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Compare all that to the Radeon HD 6570 (OEM) 2GB, which features 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 Texture Address Units, and 8 Raster Operation Units.

Pixel Rate

The Radeon HD 4850 X2 1GB should be much (more or less 285%) better at FSAA than the Radeon HD 6570 (OEM) 2GB, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 4850 X2 1GB 20000 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 14800 (285%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved 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 memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
