In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 480X 8GB are very slightly better than the Nvidia GeForce GTX 770 SLI.

The RX 480X has a 204 MHz higher core clock speed than the GTX 770, but the GTX 770 has 128 more Texture Mapping Units than the RX 480X. As a result, the GTX 770 exhibits a 107.8 GTexel/s better Texture Fill Rate than the RX 480X. 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 204 MHz higher core clock speed than the GTX 770 and the same number of Render Output Units. This results in the RX 480X providing 13.1 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.

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 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 448.5 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 SLI has 3072. However, the actual shader performance of the RX 480X is 2560 and the actual shader performance of the GTX 770 is 3333. The GTX 770 having 773 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 770 delivers a massively smoother and more efficient experience when processing graphical data than the RX 480X.

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 SLI requires 400 Watts. We would recommend a PSU with at least 500 Watts for the RX 480X and a PSU with at least 750 Watts for the GTX 770. The GTX 770 requires 250 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.

Architecture
N/A.

GPU
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.

Memory
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.

Performance
N/A.

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 SLI is a combination of 2 GeForce GTX 770 put together using NVIDIA's SLI technology.
Together, this combination offers 3072 Shader Processing Units, 256 TMUs and 64 ROPs. This, on a 256-bit memory interface, per card, of fast GDDR5. While the central unit runs at 1046MHz and goes up to 1085MHz, in Turbo Mode, the memory clock operates at 1752MHz.
Best case scenario, this combination performs better than dual-graphics GeForce GTX 690 but ultimately, its performance depends on the driver support and on the 3D application.
Therefore, and paired with a powerful processor, all demanding games are playable at the highest settings. Still, this combination might surpass the 450W barrier of TDP and so it will require a very powerful PSU.
