GeForce GTX 560 Ti vs Radeon HD 6570 (OEM) 2GB

Intro

The GeForce GTX 560 Ti features a clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 384 SPUs, 64 TAUs, and 32 ROPs.

Compare those specs to the Radeon HD 6570 (OEM) 2GB, which comes with a GPU core clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
