GeForce GT 230 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which has GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
Radeon RX 460		75 Watts
	Difference: 10 Watts (15%)

Memory Bandwidth

The Radeon RX 460 should in theory perform a lot faster than the GeForce GT 230 in general. (explain)

Radeon RX 460		112000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 73600 (192%)

Texel Rate

The Radeon RX 460 will be quite a bit (approximately 594%) faster with regards to texture filtering than the GeForce GT 230. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 52240 (594%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 is a better choice, by far. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 13040 (296%)

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 past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, 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 card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
