GeForce GTX 965M vs Radeon HD 6570 (OEM) 2GB

Intro

Compare all of that to the Radeon HD 6570 (OEM) 2GB, which features core clock speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 480 SPUs along with 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 965M		60 Watts
	Difference: 10 Watts (20%)

Memory Bandwidth

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

Texel Rate

The GeForce GTX 965M should be a lot (more or less 287%) faster with regards to anisotropic filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 44816 (287%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 965M is superior to the Radeon HD 6570 (OEM) 2GB, by a large margin. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 25008 (481%)

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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
