Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Radeon R9 380 2G		190 Watts
	Difference: 125 Watts (192%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 380 2G should be 375% faster than the GeForce GT 230 overall, due to its higher data rate. (explain)

Radeon R9 380 2G		182400 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 144000 (375%)

Texel Rate

The Radeon R9 380 2G is much (more or less 1135%) faster with regards to AF than the GeForce GT 230. (explain)

Radeon R9 380 2G		108640 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 99840 (1135%)

Pixel Rate

The Radeon R9 380 2G should be quite a bit (about 605%) more effective at AA than the GeForce GT 230, and able to handle higher resolutions while still performing well. (explain)

Radeon R9 380 2G		31040 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 26640 (605%)

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 (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
