Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M385X should in theory be a lot better than the GeForce GTS 150 in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 64000 (200%)

Texel Rate

The Radeon R9 M385X is a lot (more or less 30%) faster with regards to texture filtering than the GeForce GTS 150. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 14240 (30%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M385X is the winner, by a large margin. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 5760 (49%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
