GeForce GTX 960M vs Radeon HD 6570 (OEM) 2GB

Intro

Compare that to the Radeon HD 6570 (OEM) 2GB, which makes use of a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this specific card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 2GB		50 Watts
GeForce GTX 960M		65 Watts
	Difference: 15 Watts (30%)

Memory Bandwidth

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

Texel Rate

The GeForce GTX 960M should be quite a bit (more or less 181%) better at anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 28240 (181%)

Pixel Rate

The GeForce GTX 960M is much (about 237%) better at AA than the Radeon HD 6570 (OEM) 2GB, and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 12336 (237%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
