Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 290X should in theory be a lot superior to the Radeon R5 M330 in general. (explain)

Radeon R9 290X		320000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 305600 (2122%)

Texel Rate

The Radeon R9 290X should be quite a bit (about 583%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon R9 290X		140800 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 120200 (583%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 290X is superior to the Radeon R5 M330, by far. (explain)

Radeon R9 290X		51200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 42960 (521%)

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 (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
