VS

GeForce GTX 460 1GB vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce GTX 460 1GB uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory works at a frequency of 900 MHz on this model. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Compare all that to the Radeon HD 6570 (OEM) 1GB, which features core clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
