Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 7750 should theoretically be quite a bit superior to the Radeon R5 M330 in general. (explain)

Radeon HD 7750		72000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon HD 7750 will be much (more or less 24%) more effective at texture filtering than the Radeon R5 M330. (explain)

Radeon HD 7750		25600 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 5000 (24%)

Pixel Rate

The Radeon HD 7750 is quite a bit (approximately 55%) more effective at FSAA than the Radeon R5 M330, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 7750		12800 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 4560 (55%)

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 (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.
