Compare any two graphics cards:
VS

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

Intro

The GeForce GTX 860M comes with clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 16 Rasterization Operator 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 memory runs at a speed of 1000 MHz on this card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M 45 Watts
Radeon HD 6570 (OEM) 2GB 50 Watts
Difference: 5 Watts (11%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTX 860M is much (about 390%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 860M is superior to the Radeon HD 6570 (OEM) 2GB, by far. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
