GeForce GTX 860M vs Radeon HD 6570 (OEM) 2GB

Intro

The GeForce GTX 860M comes with a core clock frequency of 797 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

GeForce GTX 860M 76512 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 60912 (390%)

Pixel Rate

The GeForce GTX 860M should be a lot (approximately 145%) more effective at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and able to handle higher screen resolutions better. (explain)

GeForce GTX 860M 12752 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 7552 (145%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be 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 this number, the better the graphics 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 maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
