In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 280X Crossfire are significantly better than the AMD Radeon R9 380 HIS IceQ X 4GB Edition.

The R9 380 has a 140 MHz higher core clock speed than the R9 280X, but the R9 280X has 144 more Texture Mapping Units than the R9 380. As a result, the R9 280X exhibits a 106.7 GTexel/s better Texture Fill Rate than the R9 380. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The R9 380 has a 140 MHz higher core clock speed than the R9 280X, but the R9 280X has 32 more Render Output Units than the R9 380. As a result, the R9 280X exhibits a 22.7 GPixel/s better Pixel Fill Rate than the R9 380. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 380 was released over a year more recently than the R9 280X, and so the R9 380 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R9 280X.

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 R9 280X has 2048 MB more video memory than the R9 380, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 280X also has superior memory performance overall.

The R9 280X has 393.6 GB/sec greater memory bandwidth than the R9 380, which means that the memory performance of the R9 280X is massively better than the R9 380.

The Radeon R9 380 HIS IceQ X 4GB Edition has 1792 Shader Processing Units and the Radeon R9 280X Crossfire has 4096. However, the actual shader performance of the R9 380 is 1508. The R9 280X having 2588 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 280X delivers a massively smoother and more efficient experience when processing graphical data than the R9 380.

The Radeon R9 380 HIS IceQ X 4GB Edition requires 190 Watts to run and the Radeon R9 280X Crossfire requires 550 Watts. We would recommend a PSU with at least 500 Watts for the R9 380 and a PSU with at least 1000 Watts for the R9 280X. The R9 280X requires 360 Watts more than the R9 380 to run. The difference is significant enough that the R9 280X may have an adverse affect on your yearly electricity bills in comparison to the R9 380.

GPU Mini Review

Mini ReviewOverview
Radeon R9 380 HIS IceQ X 4GB Edition is a Special Edition of AMD's Performance Radeon R9 380, created by HIS.

Overclock: Central Unit
None.

Overclock: Memory Clock
None.

Frame Buffer
The Frame Buffer was doubled to 4GB.
While 4GB are needed in a few Modern Games for increased texture detail, the GPU is not powerful enough to work under other circumstances in which 4GB are needed, such as gaming above 1080p and thus a larger frame buffer is mostly a gimmick.

Cooling Solution
IceQ X is one of the quietest coolers, making the card quieter than the reference cooler. The card is below 28dB when watching movies, surfing Facebook, working. The card remains quiet whether you are gaming, online socializing, entertaining or working.

Performance
Benchmarks Indicate no Performance Boost over the Reference Radeon R9 380.
Radeon R9 280X Crossfire is a solution of two Radeon R9 280X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 280X to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to 60% better than a single Radeon R9 280X performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon R9 280X. Expect this combination to draw up to 550 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
