Because the RX 480 is a completely new architecture and its a year newer than the 390. As time goes on GPU manufacturers technology gets better so they can make things cheaper and easier.
The RX 480 has very similar performance to the R9 390 in most games, but beats it out in newer titles, especially DX12 ones (this is due to the new technology in it). The main thing it has going for it over the 390 is power consumption... its much lower than the R9 390.
The same thing happened with Nvidia, they released a GTX 1070 which dominates a GTX 980 and is the same price as what the 980 was, newer technology means higher performance for the same or lower cost

If you want a honest answer, the RX 480 Nitro card is no better than the R9390 Nitro 8 card you have.
I will explain why bellow.
Basically all a RX 480 Gpu is smaller in die size and uses a different process used to make the transistors of the Gpu chip Finfet as it`s known as.
Allows Amd to produce smaller sized transistors, and ones that have a lower electrical resistance.
So power consumption in watts is lower, the lower the wattage the cooler in theory the GPU will be, and you can pack more transistors in a smaller area.
Both the R9 and the RX line of cards have the ability ti use hardware direct x 12.
But the most important thing about any gpu chip is what the count is of the stream processors it has, And also the memory bandwidth size.
Radeon R9 390
Stream Processors: 2560
Compute Units: 40
Clock Speed: 1000MHz (1050MHz factory OC)
Texture Units: 160
ROPs: 64
Memory: 8GB GDDR5
Memory Interface: 512-bit
Memory Speed: 6.0gpbs
RX 480 card.
COMPUTE UNITS 36
STREAM PROCESSORS 2304
CLOCK SPEEDS (BOOST / BASE) 1266 MHz / 1120 MHz
PEAK PERFORMANCE Up to 5.8 TFLOPS
MEMORY CLOCK SPEED (MHZ) 1750 or higher
MEMORY BANDWIDTH 224 GB/s or higher
MEMORY INTERFACE 256 bit
MEMORY TYPE GDDR5

It's better than a R9 390, better than a RX 480 in most titles too, the RX 480 and 1060 go head to head.. Its difficult to compare AMD and Nvidia purely on specs as they use different technology and terms. E.g AMD Stream processors and Nvidia Cuda cores.
