Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 6570 (OEM) 2GB is 344% quicker than the Radeon R5 M330 in general, due to its greater bandwidth. (explain)

Radeon HD 6570 (OEM) 2GB		64000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The Radeon R5 M330 is much (more or less 32%) faster with regards to AF than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 6570 (OEM) 2GB		15600 Mtexels/sec
	Difference: 5000 (32%)

Pixel Rate

The Radeon R5 M330 is a lot (approximately 58%) more effective at anti-aliasing than the Radeon HD 6570 (OEM) 2GB, and should be able to handle higher resolutions better. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 6570 (OEM) 2GB		5200 Mpixels/sec
	Difference: 3040 (58%)

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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
