Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 290X should theoretically be a lot faster than the Radeon R5 M330 overall. (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 (more or less 583%) better at AF than the Radeon R5 M330. (explain)

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

Pixel Rate

The Radeon R9 290X is quite a bit (about 521%) more effective at FSAA than the Radeon R5 M330, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture units of the card 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
