GeForce GT 230 vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which has a core clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Radeon RX 470		120 Watts
	Difference: 55 Watts (85%)

Memory Bandwidth

In theory, the Radeon RX 470 should perform much faster than the GeForce GT 230 overall. (explain)

Radeon RX 470		211200 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 172800 (450%)

Texel Rate

The Radeon RX 470 will be a lot (approximately 1247%) better at anisotropic filtering than the GeForce GT 230. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 109728 (1247%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 470 is superior to the GeForce GT 230, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 25232 (573%)

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 max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once 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 higher screen resolutions.

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

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