In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480 Asus ROG Strix OC 8GB are noticeably better than the AMD Radeon R9 270X Crossfire.

The RX 480 has a 120 MHz higher core clock speed but 16 fewer Texture Mapping Units than the R9 270X. The lower TMU count doesn't matter, though, as altogether the RX 480 manages to provide 1.3 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 RX 480 has a 120 MHz higher core clock speed than the R9 270X, but the R9 270X has 32 more Render Output Units than the RX 480. As a result, the R9 270X exhibits a 28.2 GPixel/s better Pixel Fill Rate than the RX 480. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 480 was released over a year more recently than the R9 270X, and so the RX 480 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the R9 270X.

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 RX 480 has 4096 MB more video memory than the R9 270X, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RX 480 also has superior memory performance overall.

The R9 270X has 102.4 GB/sec greater memory bandwidth than the RX 480, which means that the memory performance of the R9 270X is massively better than the RX 480.

The Radeon RX 480 Asus ROG Strix OC 8GB has 2304 Shader Processing Units and the Radeon R9 270X Crossfire has 2560. However, the actual shader performance of the RX 480 is 3064 and the actual shader performance of the R9 270X is 2285. The RX 480 having 779 better shader performance is not particularly notable, as altogether the R9 270X performs better when taking into account other relevant data.

The RX 480 transistor size technology is 14 nm (nanometers) smaller than the R9 270X. This means that the RX 480 is expected to run slightly cooler and achieve higher clock frequencies than the R9 270X.

The Radeon RX 480 Asus ROG Strix OC 8GB requires 150 Watts to run and the Radeon R9 270X Crossfire requires 360 Watts. We would recommend a PSU with at least 500 Watts for the RX 480 and a PSU with at least 750 Watts for the R9 270X. The R9 270X requires 210 Watts more than the RX 480 to run. The difference is significant enough that the R9 270X may have an adverse affect on your yearly electricity bills in comparison to the RX 480.

GPU Mini Review

Mini ReviewOverview
Asus's Radeon RX 480 ROG Strix OC Gaming 8GB is a Performance Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture. It is a slightly overclocked version of it's younger brother, the ROG Strix Gaming RX 480 and so has the same additional feature of LED lights, a non stock cooler and a different array of diplay ports.

It equips a GPU Codenamed Ellesmere XT which is a Forth Gen GCN GPU and has 36 SM activated and thus offers 2304 Shader Processing Units, 144 TMUs and 32 ROPs.

The Central Unit runs at 1120MHz and goes up to 1266MHz, in Turbo Mode.

The GPU accesses a 8GB frame buffer of Fast GDDR5, through a 256-bit memory interface, while the Memory Clock Operates at 2000MHz.

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

Benchmarks Indicate Radeon RX 480 8GB can be almost 10% Faster than GeForce GTX 970 at 4K. However, Radeon R9 390X is still slightly faster, overall.
At 1920x1080, the default rank for all GD Graphics Card, expect its performance to be between Radeonn R9 290 and Radeon R9 290X.

System Suggestions
Radeon RX 480 8GB is best suited for resolutions up to and including 2560x1440. As this card is just a 3% overclocked version of the RX 480 we recommend the same for both, a High-End Processor and 8GB of RAM for Optimal Performance.
Radeon R9 270X Crossfire is a solution of two Radeon R9 270X put together using AMD'S Crossfire technology.
Check the page of Radeon R9 270X to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to x% better than a single Radeon R9 270X performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon R9 270X. Expect this combination to draw up to 360 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
