A Full AMD Platform Gaming PC
This AMD gaming PC build in Singapore uses the Ryzen 7 7800X3D, Powercolor Red Devil RX 9070 XT 16 GB, and Asus X870E TUF Plus Gaming motherboard, priced at $4,270 SGD. The case is the Corsair Frame 4500X RS-R ARGB in black, cooled by the Corsair Nautilus 360 RS LCD All-In-One (AIO) liquid cooler with a 360 mm radiator.
The Ryzen 7 7800X3D uses AMD's 3D V-Cache technology, which stacks 96 MB of L3 cache on the processor die. In CPU-sensitive game titles, this cache cuts frame time variance. The AM5 socket with DDR5 6000 MHz memory and the X870E chipset board, which comes with Wi-Fi 7 and Bluetooth, gives the platform room for future AMD CPU upgrades. The Powercolor Red Devil RX 9070 XT brings 16 GB of GDDR6 VRAM and AMD's RDNA 4 architecture, with FSR 4 upscaling available for titles that need higher frame rates.

PERFORMANCE
Performance at 4K
The RX 9070 XT at 4K puts 103 FPS into Resident Evil 4, per GamersNexus. Dragon's Dogma 2 runs at 70 FPS and Dying Light 2 at 62 FPS. Starfield runs at around 70 FPS at 4K, and Black Myth: Wukong lands at 46 FPS.
All five figures are rasterization results from the GamersNexus RX 9070 XT review. FSR 4 is available for titles where you want a higher frame rate on top of these numbers. The Ryzen 7 7800X3D helps keep performance smooth by reducing CPU bottlenecks in demanding games.
"At 4K and rasterized (without RT), the 9070 XT and 5070 Ti were within 6% of each other (on either side) in F1, Cyberpunk, Resident Evil 4, Starfield, Total War: Warhammer 3, and Dragon's Dogma 2."
