PERFORMANCE
Performance at 4K
The RX 9070 XT 16 GB ran Resident Evil 4 at 103 FPS and Starfield at 70 FPS at 4K, both tested by GamersNexus. Dragon's Dogma 2 reached 70 FPS, Dying Light 2 reached 62 FPS, and Black Myth: Wukong ran at 46 FPS at the same resolution.
The card carries 16 GB of GDDR6 VRAM and a 304 W TBP (Total Board Power). The Ryzen 7 7800X3D is an 8-core AM5 processor built with 3D V-Cache technology, which stacks a large L3 cache directly on the chip for stronger per-frame output across game workloads. The 64 GB of DDR5 at 6000 MHz covers gaming, recording, and background applications at the same time.
"The Radeon RX 9070 XT beats the RTX 5070 at just about everything, including ray tracing, and even challenges the 5080 in some tests."

FAQ
Frequently Asked Questions
How much does an AMD gaming PC with the RX 9070 XT cost in Singapore?
This AMD gaming PC in Singapore is priced at $3,915 SGD. It includes the Ryzen 7 7800X3D, Radeon RX 9070 XT 16 GB, 64 GB DDR5 RAM, 2 TB NVMe SSD, a 240 mm AIO cooler, 1000 W SFX PSU, and Activated Windows 11 Home, all inside the Thermaltake The Tower 250 Mini-ITX case. Mansa Computers also builds larger mid-tower RX 9070 XT configurations at different price points.
Can the RX 9070 XT run games at 4K?
Yes. In GamersNexus testing at 4K, the RX 9070 XT reached 103 FPS in Resident Evil 4, 70 FPS in Starfield, and 70 FPS in Dragon's Dogma 2. The 16 GB VRAM buffer is well-sized for 4K texture loading. FSR 4 upscaling in supported titles increases those rasterized frame rates further.
What is the Thermaltake The Tower 250 and why use it for this build?
The Thermaltake The Tower 250 is a Mini-ITX tower case designed for compact builds. It supports a full-size GPU, a 240 mm AIO cooler, and an SFX PSU in a smaller overall volume than a standard mid-tower. The B850i motherboard and Corsair SFX SF 1000 W PSU in this build are both ITX-class components selected to fit the case. The result is a 4K-capable gaming system in a significantly smaller footprint than a standard ATX build.
