In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 8GB are significantly better than the Nvidia GeForce GTX 770 PNY Enthusiast 4GB OC Edition.

The RX 480X has a 191 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 770. This results in the RX 480X providing 24.4 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 480X has a 191 MHz higher core clock speed and 32 more Render Output Units than the GTX 770. This results in the RX 480X providing 46.1 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 RX 480X was released over three years more recently than the GTX 770, and so the RX 480X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 770 when running the latest games.


The RX 480X has 4096 MB more video memory than the GTX 770, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 770 has superior memory performance.

The GTX 770 has 224.4 GB/sec greater memory bandwidth than the RX 480X, which means that the memory performance of the GTX 770 is massively better than the RX 480X.

The Radeon RX 480X 8GB has 2048 Shader Processing Units and the GeForce GTX 770 PNY Enthusiast 4GB OC Edition has 1536. However, the actual shader performance of the RX 480X is 2560 and the actual shader performance of the GTX 770 is 1706. The RX 480X having 854 better shader performance is not particularly notable, as altogether the GTX 770 performs better when taking into account other relevant data.

The RX 480X transistor size technology is 14 nm (nanometers) smaller than the GTX 770. This means that the RX 480X is expected to run slightly cooler and achieve higher clock frequencies than the GTX 770.

The Radeon RX 480X 8GB requires 150 Watts to run and the GeForce GTX 770 PNY Enthusiast 4GB OC Edition requires 230 Watts. We would recommend a PSU with at least 500 Watts for the RX 480X and a PSU with at least 600 Watts for the GTX 770. The GTX 770 requires 80 Watts more than the RX 480X to run. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the RX 480X.

GPU Mini Review

Mini ReviewOverview
Radeon RX 480X 8GB is an Upcoming High-End Graphics Card based on the Third Revision of the Graphics Core Next (GCN) Architecture.


It equips a GPU Codenamed Ellesmere XT which has 32 SM activated and thus 2048 Shader Processing Units, 128 TMUs and 64 ROPs. The central unit runs at 1250MHz and goes up to 1350MHz, in Turbo Mode.

The GPU accesses a 8GB frame buffer of Second Gen GDDR5X, through a 256-bit memory interface, while the Memory Clock Operates at 1750MHz.

Power Consumption
With a rated board TDP of 150W, it requires at least a 500W PSU with one available 8-pin connector.


System Suggestions
Radeon RX 480X 8GB is best suited for resolutions up to and including 2560x1600. We recommend a High-End Processor and 8GB of RAM for Optimal Performance.
GeForce GTX 770 PNY Enthusiast 4GB OC Edition is a special edition of GeForce GTX 770.
This edition comes with a custom dual fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1059MHz while its boost clock is now of 1111MHz and its frame buffer was doubled to 4GB, which will prove useless. The memory clock was left untouched.
Benchmarks indicate a 4% performance boost when compared to the reference card.
