Two Chinese CPUs in One 2U Server? TFNEW NK-4520
TL;DR: TFNEW launched the NK-4520, a 2U rackmount general-purpose server, on September 21, 2026. It holds up to two KP920/KP920S compute modules — Chinese-made ARM-based server processors with up to 64 cores each and up to 256 GB DDR4 RECC memory per module — plus six 3.5-inch drive bays and PCIe Gen 4 expansion. It gives procurement teams a dual-CPU 2U platform built around homegrown silicon. Get specs and pricing: sales@tfnew.com.
Core Specifications (with Plain-Language Terms)
The NK-4520 is a 2U rackmount server — 89 mm tall, which is two rack units ("U" is a standardized 44.45 mm rack height; 2U is the most common size for dual-processor machines). It takes up to two KP920/KP920S compute modules at the same time. Each module is a Chinese-made ARM-based server processor, available at 64, 48, 32 or 24 cores at ≥2.6 GHz, with up to 256 GB of DDR4 2933 MHz RECC memory per module. RECC (registered ECC) memory detects and corrects single-bit errors, which is why database and virtualization deployments prefer it over desktop RAM. Storage is six internal 3.5" SATA drive bays plus one M.2 NVMe slot. Expansion rides PCIe Gen 4 — 2x x16, 2x x8 and 1x x4 signals, plus a flexible IO slot carrying VGA, DB9 serial and 2x USB 3.0. Networking is four RJ45 gigabit ports with an out-of-band BMC management port; power is 550/800 W with 100–240 V AC input and HVDC compatibility (DC power straight from datacenter battery plants, common in large colocation sites).

Why a Dual-CPU Chinese-Made Platform Matters
For government, finance, education and telecom procurement, homegrown silicon is increasingly a hard requirement rather than an option. The NK-4520 is a standard 2U chassis built around Chinese-made processors: no foreign CPU dependency, standard PCIe Gen 4 and 3.5-inch storage, and management that already fits existing racks, security stacks and backup systems. Because compute comes in swappable modules, the same chassis can run 64-core modules in one phase of a project and 24-core modules in another without buying new hardware — a useful lever for phased rollouts and refresh cycles.
Where It Fits
- Government and regulated enterprise: systems built on domestic processors for compliance-driven refresh and procurement lists
- Database and virtualization: 2 modules × 256 GB RECC memory keep large in-memory datasets and VM farms resident
- Colocation and general-purpose hosting: six 3.5" bays for bulk storage, dual hot-swap PSUs for uptime, 650 mm depth fits standard racks
- Legacy-hardware replacement: standard 2U rails and BMC-style management let teams migrate workloads without rack rework
Why the Numbers Matter
- 2x 64-core modules: up to 128 cores and 512 GB total memory in one 2U — enough for consolidated database and virtualization workloads
- 6x 3.5" bays + M.2 NVMe: mix bulk SATA storage with fast boot and application drives in one box
- PCIe Gen 4: double the per-lane bandwidth of Gen 3 for NICs, storage controllers and accelerators
- BMC out-of-band management: power, boot and console control even when the OS is down
What TF NEW Says
"We keep hearing the same thing from enterprise buyers: they want standard, supportable servers, and they want the processor supply chain on their side of the table," said a TF NEW product manager. "The NK-4520 answers with a normal 2U chassis, dual Chinese-made CPU modules, 512 GB of RECC memory and six drive bays — a platform you can consolidate databases on today and refresh module-by-module tomorrow."
Quality and Availability
Every NK-4520 runs 48 hours of burn-in testing (sustained full load to weed out early failures) before shipping, and arrives deployment-ready: rails, BMC-enabled BIOS and a documented teardown sheet. Single-unit and volume orders are both accepted; OEM customization covers logo screening, BIOS defaults and preinstalled operating systems.
Pricing and Availability
The NK-4520 is available now. Pricing varies with module configuration (core count and memory) and order quantity. Contact sales@tfnew.com or use the request-a-quote form at www.tfnew.com/contact for volume pricing, compatibility lists and lead time.
