PERFORMANCE
1440p Gaming and Multitasking Performance
The RX 9070 XT 16 GB is well suited to high-refresh-rate 1440p gaming. In TechSpot testing, it averaged 119 FPS across 18 games at 1440p, including 125 FPS in Cyberpunk 2077: Phantom Liberty. Evetech also recorded over 200 FPS in Valorant at 1440p maximum settings. FSR 4 can further increase performance in supported games, while the 16 GB VRAM provides ample capacity for demanding textures and high settings at 1440p.
The Ryzen 9 9900X3D combines 12 Zen 5 cores and 24 threads with 128 MB of L3 cache. Tom's Hardware found it to be the fastest 12-core gaming processor in its testing, while its additional cores also provide strong performance for productivity workloads. This makes it well suited to gaming alongside OBS recording, Discord, Chrome and Photoshop. AMD's 3D V-Cache increases available L3 cache, helping improve gaming performance in workloads that benefit from reduced memory access.
"The Ryzen 9 9900X3D combines X3D gaming performance with 12 cores and 24 threads, giving this build plenty of CPU headroom for gaming, recording, streaming and production work at the same time."
