In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 380 Gigabyte G1 Gaming 4GB Edition are significantly better than the AMD Radeon HD 7850 XFX Core Edition.

The R9 380 has a 130 MHz higher core clock speed and 48 more Texture Mapping Units than the HD 7850. This results in the R9 380 providing 55.9 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 R9 380 has a 130 MHz higher core clock speed than the HD 7850 and the same number of Render Output Units. This results in the R9 380 providing 4.2 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 R9 380 was released over three years more recently than the HD 7850, and so the R9 380 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 7850 when running the latest games.

The R9 380 has 3072 MB more video memory than the HD 7850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R9 380 also has superior memory performance overall.

The R9 380 has 22.4 GB/sec greater memory bandwidth than the HD 7850, which means that the memory performance of the R9 380 is slightly better than the HD 7850.

The Radeon R9 380 Gigabyte G1 Gaming 4GB Edition has 1792 Shader Processing Units and the Radeon HD 7850 XFX Core Edition has 1024. However, the actual shader performance of the R9 380 is 1508 and the actual shader performance of the HD 7850 is 749. The R9 380 having 759 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 380 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7850.

The Radeon R9 380 Gigabyte G1 Gaming 4GB Edition requires 190 Watts to run but there is no entry for the Radeon HD 7850 XFX Core Edition. We would recommend a PSU with at least 500 Watts for the R9 380 and a PSU with at least 500 Watts for the HD 7850. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
Radeon R9 380 Gigabyte G1 Gaming 4GB Edition is a Special Edition of AMD's Performance Radeon R9 380, created by Gigabyte.

Overclock: Central Unit
The Central Unit is now of 990MHz, instead of 970MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 1425MHz, instead of 1375MHz.

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
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 2% Performance Boost over the Reference Radeon R9 380.
Radeon HD 7850 XFX Core Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
This edition features a special cooling system that allows twice as much heat dissipation when compared to the reference AMD cooling system but its performance is still the same, as there's no over-clocking out of the box.
