Radeon HD 4730 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which features core speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
Radeon HD 4730		140 Watts
	Difference: 65 Watts (87%)

Memory Bandwidth

In theory, the Radeon RX 460 should be 94% faster than the Radeon HD 4730 overall, because of its greater data rate. (explain)

Radeon RX 460		112000 MB/sec
Radeon HD 4730		57600 MB/sec
	Difference: 54400 (94%)

Texel Rate

The Radeon RX 460 should be quite a bit (about 173%) more effective at AF than the Radeon HD 4730. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 38640 (173%)

Pixel Rate

The Radeon RX 460 will be a lot (more or less 211%) faster with regards to FSAA than the Radeon HD 4730, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 11840 (211%)

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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
