Radeon R9 M375X		72000 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M375X will be quite a bit (approximately 97%) better at texture filtering than the Radeon R5 M330. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 20000 (97%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M375X is a better choice, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 8000 (97%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video 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 amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
