Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X will be 88% quicker than the GeForce GT 230 overall, because of its greater data rate. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R9 M265X should be a lot (approximately 161%) more effective at texture filtering than the GeForce GT 230. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 14200 (161%)

Pixel Rate

The Radeon R9 M265X is much (about 109%) faster with regards to FSAA than the GeForce GT 230, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 4800 (109%)

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 (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
