In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 490X 8GB are massively better than the AMD Radeon R9 380 PowerColor PCS+ 4GB Edition.

The RX 490X has a 20 MHz higher core clock speed and 272 more Texture Mapping Units than the R9 380. This results in the RX 490X providing 274.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 490X has a 20 MHz higher core clock speed and 96 more Render Output Units than the R9 380. This results in the RX 490X providing 96.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 490X was released less than a year after the R9 380, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The RX 490X has 4096 MB more video memory than the R9 380, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the R9 380 has superior memory performance.

The R9 380 has 188.8 GB/sec greater memory bandwidth than the RX 490X, which means that the memory performance of the R9 380 is massively better than the RX 490X.

The Radeon RX 490X 8GB has 6144 Shader Processing Units and the Radeon R9 380 PowerColor PCS+ 4GB Edition has 1792. However, the actual shader performance of the R9 380 is 1493. The RX 490X having 4651 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 490X delivers a massively smoother and more efficient experience when processing graphical data than the R9 380.

The RX 490X transistor size technology is 14 nm (nanometers) smaller than the R9 380. This means that the RX 490X is expected to run slightly cooler and achieve higher clock frequencies than the R9 380.

The Radeon RX 490X 8GB requires 250 Watts to run and the Radeon R9 380 PowerColor PCS+ 4GB Edition requires 190 Watts. We would recommend a PSU with at least 600 Watts for the RX 490X and a PSU with at least 500 Watts for the R9 380. The RX 490X requires 60 Watts more than the R9 380 to run. The difference is significant enough that the RX 490X may have an adverse affect on your yearly electricity bills in comparison to the R9 380.

System Suggestions
Radeon RX 490X 8GB is best suited for resolutions up to and including 3840x2160. We recommend a High-End Processor and 16GB of RAM for Optimal Performance.
Overview
Radeon R9 380 PowerColor PCS+ 4GB Edition is a Special Edition of AMD's Performance Radeon R9 380, created by PowerColor.

Overclock: Central Unit
The Central Unit is now of 980MHz, instead of 970MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 1475MHz, instead of 1375MHz.

Frame Buffer
The Frame Buffer was doubled to 4GB: a gimmick which doesn't yield any performance boost and can be considered marketing to lure consumers into paying more for the same product.


Cooling Solution
PCS-Professional Cooling System: The unique cooling technology can decrease operating environment temp. Effectively, and enhance headroom for OC capabilities.
