Tiny Corp’s Four-GPU Tinybox Packs AMD EPYC Power, but Buying One Isn’t Straightforward

Tiny Corp's Tinybox starts at $7,000 with no GPUs. Here is what the AMD EPYC G4 build includes, what the GPU add-ons cost, and the buying terms to check first.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Tiny Corp’s configurator lists its G4 Tinybox at $7,000 with no GPUs installed. That base price buys a water-cooled 32-core AMD EPYC processor and slots for up to four GPUs, but every accelerator is an add-on, the machine is built to order, and the purchase terms (bank-transfer payment, possible compliance paperwork, a 20% restocking fee) are stricter than a typical workstation checkout. Prices and options can change, so confirm them on the configurator before you budget.

What the base Tinybox includes

Tiny Corp markets the machine with the line “A computer for deep learning. Configured by you.” The G4 base build shown on the official product page includes:

As an Amazon Associate I earn from qualifying purchases.

  • A G4 / PCIe 4 platform on a server-grade motherboard with a BMC (baseboard management controller)
  • A water-cooled 32-core AMD EPYC CPU
  • 32 GB of DDR4 memory
  • A 1 TB boot SSD
  • A 1700 W power supply
  • Slots for up to four GPUs, which the page describes as full-fabric PCIe

Tiny Corp’s separate Tiny Shop lists an older Green v2 system with four RTX 5090 cards, shown as out of stock. It is a different product from the configurable G4 and G5 platforms and should not be used to judge the current configurator’s pricing or specifications.

GPU, memory and storage options

The table combines prices from the official configurator with the wider ranges that Notebookcheck reported on October 8, 2026.

Option Price shown Details reported
G4 base system, no GPU $7,000 32 GB DDR4 in the base build; up to 128 GB RAM reported (Notebookcheck, October 8, 2026)
Four AMD Radeon RX 9070 XT +$4,000 The only four-GPU option listed
One RTX 6000 +$19,000 RTX generation not stated in the reports
Two RTX 6000 +$38,000 RTX generation not stated in the reports
G5 / DDR5 / Genoa base system $12,000 Up to 192 GB RAM reported (Notebookcheck, October 8, 2026); memory and storage upgrades selectable

Notebookcheck also reports storage configurations up to 16 TB, including the boot drive and RAID drives, and a maximum configuration total of $64,000. That figure is an upper bound from the report; the report does not itemize which combination produces it.

Added to the $7,000 base, the listed GPU prices come to about $11,000 with four RX 9070 XT cards, $26,000 with one RTX 6000, and $45,000 with two. Those totals exclude memory and storage upgrades, taxes, duties and shipping. Note that the four-card option is the only four-GPU configuration; the RTX options top out at two cards.

Why buying one isn’t straightforward

Made to order, with a short payment window

Each Tinybox is made to order, and Tiny Corp expects dispatch within one to eight weeks. Payment is by bank transfer or wire. The official page says payment must arrive within five days of order confirmation to guarantee the order.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Shipping, taxes and import costs

Tiny Corp says it ships insured UPS orders worldwide, but only to countries available at checkout. It estimates three to ten days in transit after dispatch. Buyers pay applicable taxes. International buyers are also responsible for import duties, fees and VAT, which the page does not estimate.

Returns

Returns are accepted within 30 days. A 20% restocking fee applies, and the buyer pays return shipping. On a $26,000 order, the restocking fee alone would be $5,200 before shipping.

Nvidia configurations and destination limits

Nvidia GPU configurations may require a KYC (know-your-customer) compliance form that states the intended use and installation address. Tiny Corp warns that US regulations can prevent shipments to some countries. The official page does not list eligible destinations, so check before you order an RTX configuration.

Power and installation

The G4 listing gives a 1700 W power supply but no electrical installation guide for the configurable machine. tinygrad’s Tinybox documentation covers earlier configurations with two 1600 W power supplies. When both run at full load, those systems can exceed what a typical 120 V household circuit supplies. The documentation recommends separate circuits and describes a GPU power-limiting script for certain single-outlet setups.

  • 【High Performance Processor】The X1-470 Mini PC feature with AMD Ryzen AI 9 HX470(12C/24T) processor. The faster performance can handle productivity tasks smoothly. It widely used for image editing, browsing, light games,watching movies, daily life, programming etc.
  • 【OCulink Support】This mini pc was equipped with a OCulink port. OCuLink is a standard for externally connecting PCI Express, the speed is PCIe4.0 x4=64G. With this port, you could install external GPU with faster support speeds compared to Thunderbolt 4 and USB4. Note: *Non-hot-swappable, OCulink requires one M.2 2280 PCIe4.0 SSⅮslot*.
  • 【2.5G Lan Port and Wi-Fi 7 Support】It comes with 2.5G Lan Port for wired connection and and Wi-Fi 7 / BT5.4 for wireless connection, which increased the network speed greatly and expand its functions and improved performance of computer to a large extent and allows you to use more networks such as software routers (OpenWRT / DD-WRT / Tomato etc.), firewalls, NAT, network isolation etc.
  • 【Great Cooling Efficiency】Large-area cooling vents are designed on the sides and bottom of the chassis, forming a three-dimensional airflow channel. Cold air is drawn in from the bottom, while hot air is expelled through the rear sides, effectively preventing heat buildup. The bottom is equipped with an active memory and hard drive (SSD) cooler, ensuring that the memory and SSD operate at full speed at all times, thus maintaining a smooth and lag-free system performance.
  • 【Built-in Microphones(Dual) and Speaker】The dual digital microphones feature intelligent noise-reduction technology, enabling precise focusing on human voices and clear sound capture even in noisy environments. This ensures seamless communication and unobstructed expression in scenarios such as video conferences, online classes, voice creation, and more.

Those instructions describe a different power arrangement. Do not apply them to the current single-PSU listing. Ask Tiny Corp for the circuit requirement of your exact build, particularly with four GPUs installed.

Software and workload evidence

tinygrad’s documentation says Tinyboxes are used heavily in tinygrad’s own continuous integration and describes the platform for AI infrastructure and for training and inference work. The default system image includes tinygrad and PyTorch, and users can install other frameworks. That establishes intended use, not speed.

No independent benchmark of the new configurable model is available as of October 2026, so this article makes no performance or value-for-money claim about any option.

Comparing configurations

Compare options on the axes that the configurator and reports both expose:

  • Platform and PCIe generation: G4 (PCIe 4) against G5 (PCIe 5, per Notebookcheck)
  • GPU type and count
  • Memory type and capacity
  • Storage layout, including RAID
  • Total price after taxes, duties and shipping
  • Power and cooling requirements
  • Availability and destination restrictions

Open questions to settle with Tiny Corp before ordering

  • Which RTX 6000 generation does each Nvidia configuration use?
  • Does the checkout accept orders for my country, and does a four-GPU build need a KYC form?
  • What circuit capacity does the exact build require, and how many separate circuits are recommended?
  • What do memory and storage upgrades add to the GPU configuration I want?
  • What import duties, fees and VAT will apply to my delivery address?

The Bottom Line

The Tinybox is a configurable, made-to-order machine whose $7,000 base price is the smallest part of the cost. GPU choice, electrical capacity, Nvidia compliance and the cost of a return determine whether it suits your project, so settle those points with Tiny Corp before you commit.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
