TOPC TXA2 Packs 192GB RAM and AMD Ryzen AI Max+ for $6,800
Chinese boutique hardware vendor TOPC has introduced the TXA2, an unconventional 2.5-liter workstation combining AMD's Ryzen AI Max+ PRO 495 processor with 192GB of soldered LPDDR5X memory. The mini rig allows up to 160GB of RAM to function as dedicated VRAM for local AI models, but it starts at a steep $6,499.
160GB of usable VRAM in a 2.5-liter chassis
Running large parameter AI models locally usually demands enterprise server racks or multiple power-hungry discrete graphics cards. TOPC takes a radically different route with the TXA2, packing AMD's high-end silicon into a copper-toned enclosure that displaces just 2.5 liters and weighs 2.319 kg.
At the center sits the Ryzen AI Max+ PRO 495, pairing 16 Zen 5 CPU cores and 32 threads with integrated Radeon 8065S graphics. What makes this setup remarkable is memory pooling: the motherboard carries 192GB of fast LPDDR5X-8533 memory soldered in place, and the architecture can allocate up to 160GB directly to the GPU.
That massive pool lets developers keep hefty neural networks entirely in memory, echoing edge appliances like the Sipeed MaixStation without requiring custom NPU toolchains. The catch is zero expandability: that soldered memory pool cannot be upgraded down the line.

Four internal fans and unexpected storage depth
Taming a sustained 120W thermal load inside a chassis measuring only 18cm wide and 7.8cm thick requires aggressive airflow. TOPC equipped the TXA2 with four individual fans: two dedicated to the processor package and two managing internal storage and board components. The system handles brief peaks up to 140W, venting exhaust above the rear ports.
Storage layout is unusually generous for this volume. The motherboard houses four M.2 2280 NVMe slots, split between two full-speed PCIe 4.0 x4 lanes and two PCIe 4.0 x2 connections. Buyers can select factory builds with 2TB or 4TB solid-state drives.
Connectivity is equally dense. The rear panel offers 10GbE and 2.5GbE LAN ports, DisplayPort 2.1, HDMI 2.1, USB4, and four USB 3.2 Gen1 connectors, supporting up to four simultaneous 8K monitors. The front adds three USB 3.2 Gen2 ports, an SDXC card slot, Wi-Fi 7, and Bluetooth 5.4.
Fitting 192GB of unified memory and 120W sustained cooling into a 2.5-liter box is brilliant engineering. Yet handing $6,800 to an unknown brand backed only by PayPal and a single-year warranty is a massive leap of faith. Unless running 70B parameter models on your desk without server fans is critical today, wait for established OEMs to ship similar silicon.
Availability and international pricing
TOPC sells the TXA2 directly online with transactions processed through PayPal. Pricing begins at $6,499 for the 2TB model and climbs to $6,799 for 4TB of storage, plus a flat $69 international shipping fee.
Those quotes exclude regional import duties, customs fees, and local sales tax. European customers face final landing costs well above €7,200 after standard 20% VAT is applied. TOPC backs the machine with only a one-year warranty, which makes wiring thousands of dollars to an obscure vendor a real consideration for corporate buyers.
Frequently asked questions
How much RAM does the TOPC TXA2 have?
The TOPC TXA2 features 192GB of soldered LPDDR5X memory running at 8,533MHz, with up to 160GB assignable to the GPU for AI models.
What is the price of the TOPC TXA2?
The workstation costs $6,499 for the 2TB version and $6,799 for the 4TB configuration, excluding $69 shipping, taxes, and import duties.
Can you upgrade the RAM or storage on the TOPC TXA2?
The 192GB RAM is permanently soldered to the motherboard and cannot be upgraded. Storage is flexible, offering four standard M.2 2280 NVMe SSD slots.
