Purpose-built desktop for creative

This system pairs a 12-core AMD Ryzen 9 9900X3D processor with 64GB of DDR5 memory and a Radeon RX 9070 XT graphics card. It targets professionals who need strong multi-threaded compute for rendering or simulation alongside high-frame-rate gaming. The liquid-cooled tower runs Windows 11 Pro and includes Wi-Fi 7 connectivity.

Storage capacity and headroom

Dual 4TB Samsung 990 PRO drives provide 8TB of NVMe storage with sequential reads up to 7450 MB/s and writes up to 6900 MB/s. That volume comfortably holds large project libraries, game installs and scratch files. The four memory slots support up to 192GB total, so 64GB leaves headroom for future expansion without replacing modules.

Deciding specification: 12-core X3D CPU

The Ryzen 9 9900X3D delivers 12 cores, 24 threads and a 5.50 GHz maximum boost backed by 128MB of L3 cache. That cache architecture is the single factor that lifts minimum frame rates in cache-sensitive titles and accelerates compile and simulation workloads. Buyers who do not need that specific cache advantage should consider a different processor tier.

Questions about this item

Will the 64 GB DDR5 memory in this PC limit me if I keep my current DDR5 modules?

The motherboard has four DDR5 slots and supports up to 192 GB, so any DDR5 modules you already own can be added alongside the installed 64 GB kit.

How can I verify the 240 mm liquid cooler is keeping the Ryzen 9 9900X3D at safe temperatures after I build the system?

Boot into Windows 11 Pro and check the CPU temperature in BIOS or a monitoring utility; the cooler is designed for the 12-core 4.4 GHz processor and should report idle temperatures well below the thermal limit.

Which components are already inside the Antec P20 case and what must I purchase separately to start working?

The case arrives fully assembled with the X870 motherboard, Ryzen 9 9900X3D, 64 GB DDR5, two 4 TB Samsung 990 PRO SSDs, Radeon RX 9070 XT 16 GB, 850 W PSU, Windows 11 Pro and Wi-Fi 7 — no extra parts are required.
