Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be much faster than the GeForce GT 230 overall. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 57600 (150%)

Texel Rate

The Radeon R9 M385X is a lot (about 600%) faster with regards to texture filtering than the GeForce GT 230. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 52800 (600%)

Pixel Rate

The Radeon R9 M385X will be a lot (approximately 300%) more effective at full screen anti-aliasing than the GeForce GT 230, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 13200 (300%)

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 information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 bandwidth is, the lower the ability to reach the max fill rate.
