RX 9070 XT with Samsung GDDR6 memory turned out to be slower: up to -2% to performance
An independent study has appeared on the Chinese platform Bilibili, revealing RX 9070 XT performance drop with Samsung GDDR6 memory compared to similar graphics cards using SK Hynix chips. The results were confirmed after testing more than 20 graphics cards.
The difference was between 1 and 2% in synthetic benchmarks, including 3DMark Speedway, where even overclocked versions with Samsung memory were inferior to standard models on SK Hynix. The researcher also reported Samsung increased memory latency, reaching 380 ns, versus 360 ns for competitors.
AMD Confirms Issue, citing the specific timings and architectural features of Samsung GDDR6. This became another example of the impact of memory type on real-world performance even within a single model. GPU.
Even at the same frequencies, the RX 9070 XT with SK Hynix memory consistently outperforms its Samsung GDDR6 counterparts, despite the other parameters being identical. The problem concerns all batches with Samsung chips regardless of the video card manufacturer.
