Radeon R9 280X vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which uses a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this particular card. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Memory Bandwidth

Theoretically speaking, the Radeon R9 280X should be 157% quicker than the Radeon RX 460 in general, because of its greater data rate. (explain)

Radeon R9 280X		288000 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 176000 (157%)

Texel Rate

The Radeon R9 280X should be quite a bit (about 78%) faster with regards to anisotropic filtering than the Radeon RX 460. (explain)

Radeon R9 280X		108800 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 47760 (78%)

Pixel Rate

The Radeon R9 280X should be much (about 56%) more effective at anti-aliasing than the Radeon RX 460, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 280X		27200 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 9760 (56%)

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 data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
