VS

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

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this specific model. It features 384 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific card. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB 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 memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few 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.
