Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260X are marginally better than the AMD Radeon HD 6870.
The Radeon R7 260X has a 200 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon HD 6870. This results in the Radeon R7 260X providing 11.2 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 Radeon R7 260X has a 200 MHz higher core clock speed than the Radeon HD 6870, but the Radeon HD 6870 has 16 more Render Output Units than the Radeon R7 260X. As a result, the Radeon HD 6870 exhibits a 11.2 GPixel/s better Pixel Fill Rate than the Radeon R7 260X. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The Radeon R7 260X was released over a year more recently than the Radeon HD 6870, and so the Radeon R7 260X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 6870.
The Radeon R7 260X has 1024 MB more video memory than the Radeon HD 6870, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.
The Radeon HD 6870 has 30.4 GB/sec greater memory bandwidth than the Radeon R7 260X, which means that the memory performance of the Radeon HD 6870 is noticeably better than the Radeon R7 260X.
The Radeon R7 260X has 896 Shader Processing Units and the Radeon HD 6870 has 1120. However, the actual shader performance of the Radeon R7 260X is 838 and the actual shader performance of the Radeon HD 6870 is 504. The Radeon R7 260X having 334 better shader performance is not particularly notable, as altogether the Radeon HD 6870 performs better when taking into account other relevant data.
The Radeon R7 260X transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6870. This means that the Radeon R7 260X is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6870. While they exhibit similar graphical performance, the Radeon R7 260X should consume less power than the Radeon HD 6870.
The Radeon R7 260X requires 115 Watts to run and the Radeon HD 6870 requires 151 Watts. We would recommend a PSU with at least 450 Watts for the Radeon R7 260X and a PSU with at least 500 Watts for the Radeon HD 6870. The Radeon HD 6870 requires 36 Watts more than the Radeon R7 260X to run. The difference is significant enough that the Radeon HD 6870 may have a slight adverse affect on your yearly electricity bills in comparison to the Radeon R7 260X.
|Mini Review||Overview |
Radeon R7 260X is a Fast-Middle-Class Graphics Card based on the Second Revision of the Graphics Core Next (GCN) Architecture.
Radeon R7 260X Equips a GPU Codenamed Bonaire XTX which is a Second Gen GCN GPU and is an upgraded version of the Bonaire XT GPU previously used on Radeon 7790.
Bonaire XT has 14 Compute Units activated and thus offers 896 Shader Processing Units, 56 TMUs and 16 ROPs.
The Central Unit is clocked at 1100MHz.
The GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 128-bit Memory Interface. The Memory Clock Operates at 1625Hz.
Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 2GB. This would be useful were the Graphics Card suited for 1080p Gaming, which is not the case.
With a rated board TDP of 115W, it requires at least a 500W PSU with one available 6-pin connector.
Radeon R7 260X is the Fastest of all Radeon R7 260X Variants and Delivers Performance almost up to 10% over the Older Radeon HD 7790.
Radeon R7 260X is best suited for resolutions up to and including 1600x900. We recommend a Middle-Class Processor and 8GB of RAM for Optimal Performance.
|Radeon HD 6870 is a fast high-end card made in 40nm fabrification process. It is based on the Barts XT architecure. Featuring 1120 Shaders, 56 texture units and 32 ROPs paired with fast 1GB GDDR5 video memory working on 1050 MHz, and core clock running at 900 MHz. Most latest games will be playable on High-Ultra and no AA with 1080p, except Demanding ones such as Far Cry 3 or Assassins Creed 3, which requires lowering settings to high, without Anti-Aliasing, while Crysis 3 needs medium-high graphical settings in order to achieve playable FPS. |
