In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 370 MSI Gaming 4GB Edition are significantly better than the AMD Radeon HD 6870 PowerColor 1GB Edition.

The R7 370 has a 120 MHz higher core clock speed and 8 more Texture Mapping Units than the HD 6870. This results in the R7 370 providing 14.9 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 R7 370 has a 120 MHz higher core clock speed than the HD 6870 and the same number of Render Output Units. This results in the R7 370 providing 3.8 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 R7 370 was released over three years more recently than the HD 6870, and so the R7 370 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 6870 when running the latest games.

The R7 370 has 3072 MB more video memory than the HD 6870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the R7 370 also has superior memory performance overall.

The R7 370 has 48 GB/sec greater memory bandwidth than the HD 6870, which means that the memory performance of the R7 370 is noticeably better than the HD 6870.

The Radeon R7 370 MSI Gaming 4GB Edition has 1024 Shader Processing Units and the Radeon HD 6870 PowerColor 1GB Edition has 1120. However, the actual shader performance of the R7 370 is 931 and the actual shader performance of the HD 6870 is 504. The R7 370 having 427 better shader performance and an altogether better performance when taking into account other relevant data means that the R7 370 delivers a significantly smoother and more efficient experience when processing graphical data than the HD 6870.

The R7 370 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the R7 370 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The Radeon R7 370 MSI Gaming 4GB Edition requires 110 Watts to run but there is no entry for the Radeon HD 6870 PowerColor 1GB Edition. We would recommend a PSU with at least 500 Watts for the R7 370 and a PSU with at least 500 Watts for the HD 6870. 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 R7 370 MSI Gaming 4GB Edition is a Special Edition of AMD's Fast-Middle-Class Radeon R7 370, created by MSI.

Overclock: Central Unit
The Central Unit is now of 1020MHz, instead of 925MHz, while the Boost Clock achieves 1070MHz, instead of 975MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 1425MHz, instead of 1400MHz.

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
MSIís Twin Frozr V Thermal Designs are equipped with Zero Frozr technology which was first introduced by MSI back in 2008. Zero Frozr technology eliminates fan noise in low-load situations by stopping the fans when they are not needed. Compared to other graphics cards, there is no continuous hum of airflow to tell you there's a powerful graphics card in your gaming rig.

Benchmarks Indicate a 4% Performance Boost over the Reference Radeon R7 370.
Radeon HD 6870 PowerColor 1GB Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
It has no new features and so it can be addressed as a renamed Radeon HD 6870. Therefore its performance is exactly like the standard's.
