GeForce GTX 560 Ti vs Radeon HD 3470 512MB

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this specific card. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the Radeon HD 3470 512MB, which comes with a core clock frequency of 800 MHz and a GDDR3 memory frequency of 950 MHz. It also uses a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 get to the max fill rate.
