GeForce GTX 850M vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce GTX 850M makes use of a 28 nm design. nVidia has set the core speed at 876 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this model. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 is also dependant 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 max fill rate.
