In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 Sapphire GHz OC Edition CrossFire are significantly better than the AMD Radeon R9 270.

The HD 7870 has a 150 MHz higher core clock speed and 80 more Texture Mapping Units than the Radeon R9 270. This results in the HD 7870 providing 96 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 HD 7870 has a 150 MHz higher core clock speed and 32 more Render Output Units than the Radeon R9 270. This results in the HD 7870 providing 38.4 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 Radeon R9 270 was released over a year more recently than the HD 7870, and so the Radeon R9 270 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7870.

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 HD 7870 has 2048 MB more video memory than the Radeon R9 270, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 also has superior memory performance overall.

The HD 7870 has 140.8 GB/sec greater memory bandwidth than the Radeon R9 270, which means that the memory performance of the HD 7870 is massively better than the Radeon R9 270.

The Radeon HD 7870 Sapphire GHz OC Edition CrossFire has 2560 Shader Processing Units and the Radeon R9 270 has 1280. However, the actual shader performance of the HD 7870 is 2285 and the actual shader performance of the Radeon R9 270 is 1006. The HD 7870 having 1279 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a massively smoother and more efficient experience when processing graphical data than the Radeon R9 270.

The Radeon R9 270 requires 150 Watts to run but there is no entry for the HD 7870. We would recommend a PSU with at least 500 Watts for the HD 7870 and a PSU with at least 500 Watts for the Radeon R9 270. 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 ReviewRadeon HD 7870 Sapphire GHz OC Edition is a special edition of the powerful Radeon HD 7870. See the standard version for more information about it.
The differences include an increase in the core-clock that went from 1000MHz to 1050MHz and in the memory clock raised from 1200MHz to 1250MHz and a new quiet and efficient cooling system is also available.
Benchmarks indicate a 4,0% performance boost when compared to the standard Radeon HD 7870.
All games, including demanding one's, will run on the highest settings.
Overview
Radeon R9 270 is a Performance Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

GPU
It equips a GPU Codenamed Curacao PRO which has 20 Compute Units activated and thus offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit is clocked at 900MHz and goes up to 925MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1400MHz.

Power Consumption
With a rated board TDP of 150W, it requires at least a 500W PSU with one available 6-pin connector.

Performance
Radeon R9 270 is a direct rebrand of Radeon HD 8860 (OEM) which is essentially a Power Optimized Radeon HD 7870/Radeon HD 8870 (OEM).
It proves to be as fast as Radeon HD 7870/Radeon HD 8870 (OEM) .

System Suggestions
Radeon HD 8860 (OEM) is best suited for resolutions up to and including 1920x1080. We recommend a Strong Processor (Intel Core i5 Quad Core/AMD FX Six Core) and 8GB of RAM for Optimal Performance.
