AMD RDNA 4 Performance Issues, RX 9050 Benchmarks, and External GPU Gains Explained
Benchmark Test Results: RDNA 4 Falls Short in 4K Gaming
In a recent benchmark test, AMD’s RDNA 4 architecture demonstrated lower performance than its predecessors when running The Sinking City 2 at 4K resolution, according to findings published by GameGPU. The test revealed that without external GPU support, RDNA 4 delivered suboptimal results compared to earlier RDNA generations, despite the architecture’s intended improvements.
External GPU Boosts Performance by 183% in 4K Scenarios
GameGPU’s analysis highlighted that connecting an external GPU via Steam Machine significantly boosted 4K performance, achieving an 183% improvement over internal GPU configurations. This suggests that RDNA 4’s performance in high-resolution gaming scenarios may be constrained by hardware limitations unless augmented with external solutions.
RX 9050 vs. RX 9060 XT: Performance Disparity and Pricing
The study also compared the Digital Focus RX 9050 and RX 9060 XT models. While the RX 9050 operated at half the speed of the RX 9060 XT, the price difference between the two was described as “minimal” by GameGPU. This contrast raises questions about the value proposition of the RX 9050 in markets where performance per dollar is a critical factor.

AMD’s Silence and Industry Analysts’ Take on RDNA 4’s Trade-Offs
AMD has not publicly commented on the findings, leaving the company’s response to the performance data unverified. Industry analysts note that RDNA 4’s design prioritizes efficiency over raw processing power, a trade-off that may impact its appeal in competitive gaming environments.
Ongoing Testing Aims to Clarify RDNA 4’s Performance Across Titles
Further testing is underway to determine whether RDNA 4’s performance gaps persist across other titles or hardware configurations. GameGPU plans to release additional data in the coming weeks, which could provide clearer insights into the architecture’s strengths and weaknesses.
