In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390 Gigabyte G1 Gaming 8GB Edition are noticeably better than the AMD Radeon HD 7970 GHz Toxic 6GB Edition.

The HD 7970 has a 75 MHz higher core clock speed than the R9 390, but the R9 390 has 32 more Texture Mapping Units than the HD 7970. As a result, the R9 390 exhibits a 23.2 GTexel/s better Texture Fill Rate than the HD 7970. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7970 has a 75 MHz higher core clock speed than the R9 390, but the R9 390 has 32 more Render Output Units than the HD 7970. As a result, the R9 390 exhibits a 30.4 GPixel/s better Pixel Fill Rate than the HD 7970. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 390 was released over a year more recently than the HD 7970, and so the R9 390 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7970.

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 390 has 2048 MB more video memory than the HD 7970, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 390 also has superior memory performance overall.

The R9 390 has 96 GB/sec greater memory bandwidth than the HD 7970, which means that the memory performance of the R9 390 is massively better than the HD 7970.

The Radeon R9 390 Gigabyte G1 Gaming 8GB Edition has 2560 Shader Processing Units and the Radeon HD 7970 GHz Toxic 6GB Edition has 2048. However, the actual shader performance of the R9 390 is 2230 and the actual shader performance of the HD 7970 is 2002. The R9 390 having 228 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 390 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7970.

The Radeon R9 390 Gigabyte G1 Gaming 8GB Edition requires 275 Watts to run and the Radeon HD 7970 GHz Toxic 6GB Edition requires 265 Watts. We would recommend a PSU with at least 600 Watts for the R9 390. The R9 390 requires 10 Watts more than the HD 7970 to run. The difference is not significant enough for the R9 390 to have a noticeably larger impact on your yearly electricity bills than the HD 7970.

Mini ReviewOverview
Radeon R9 390 Gigabyte G1 Gaming 8GB Edition is a Special Edition of AMD's High-End Radeon R9 390, created by Gigabyte.

Overclock: Central Unit
The Central Unit is now of 1025MHz, instead of 1000MHz.

Overclock: Memory Clock
None.

Frame Buffer
Untouched.


Cooling Solution
WINDFORCE 2X Cooling System: The airflow is spilt through the triangle design at the fan edge, and is guided smoothly through the fan by special 3D stripe curve design. At the same time, it effectively enhanced the cooling capacity while reducing air turbulence.

Performance
Benchmarks Indicate a 1% Performance Boost over the Reference Radeon R9 390.
Radeon HD 7970 GHz Toxic 6GB Edition is a special edition of Radeon HD 7970 GHz Edition.
It comes with 2 modes: a default core-clock of 1050MHz that goes up to 1100MHz in Turbo or a default core-clock of 1100MHz that goes up to 1200MHz. It also features a new cooling system with 2 huge fans. The memory clock will also be raised to 1600MHz, if using the highest option (lethal Turbo mode).
Using the lethal turbo mode, the performance boost is around 6% than reference Radeon HD 7970 GHz Edition.
