PERFORMANCE
Performance at 4K
In testing by GamersNexus, the RX 9070 XT 16 GB hit 103 FPS in Resident Evil 4, 70 FPS in Starfield, 70 FPS in Dragon's Dogma 2, 62 FPS in Dying Light 2, and 46 FPS in Black Myth: Wukong, all at 4K. The card draws 304 W TBP (Total Board Power) at load, per AMD's official specification.
The Ryzen 7 9800X3D's 3D V-Cache keeps the CPU from bottlenecking the RX 9070 XT in game-heavy loads. The 64 GB of DDR5 at 6400 MHz covers memory-intensive workloads alongside gaming, and the 2 TB NVMe SSD keeps load times short. The build ships with Activated Windows 11 Home 64-Bit installed.
"The Radeon RX 9070 XT beats the RTX 5070 at just about everything, including ray tracing, and even challenges the 5080 in some tests."

For pure gaming, 64 GB exceeds what most titles need - but it covers any workflow without needing an upgrade later.
