The Lucebox Zero 495 is advertised with AMD’s Ryzen AI MAX+ PRO 495, 128 GB or 192 GB of unified memory, and a Radeon AI PRO R9700. Lucebox lists the workstation at $5,999, but its detailed components and benchmark pages describe a different, 128 GB Ryzen AI MAX+ 395 configuration. Those distinctions matter: the advertised price is not confirmed for every memory tier, and the two memory pools should not be added together and called VRAM.
What Lucebox advertises—and what its detailed pages specify
Lucebox positions the Zero 495 as a workstation for local AI inference, aimed at developers and teams that want to run models on their own hardware. The company says it ships with an inference engine and preloaded software, and supports coding-agent clients through an OpenAI- and Anthropic-compatible API. These are vendor descriptions of the system’s intended use and software behavior.

The product page currently advertises the Ryzen AI MAX+ PRO 495 with 128 GB or 192 GB of unified memory and a Radeon AI PRO R9700. However, Lucebox’s components page lists a production system built around the Ryzen AI MAX+ 395, with 128 GB LPDDR5X-8000. Its performance page also describes results from a 395-based machine with 128 GB. Treat the advertised 495 configurations and the detailed 395 configuration as separate; the published benchmark results are not established for the advertised 495 system.

Why “up to 224 GB” does not mean 224 GB of VRAM
The 128 GB system-memory figure and the R9700’s 32 GB of dedicated GDDR6 describe separate memory pools. On the detailed 395-based configuration, 128 GB of LPDDR5X is shared by the APU and its integrated graphics, while the discrete R9700 has its own 32 GB GDDR6. Adding capacities may yield a larger aggregate figure for some descriptions, but it does not turn them into one unified pool or give the R9700 160 GB of dedicated VRAM. Lucebox’s materials do not establish that “up to 224 GB” is one unified or GPU-dedicated memory pool.
For model and workload planning, check which memory a particular software stack can use and how it handles transfers between devices. A system-memory capacity, dedicated GPU memory, and a software-managed aggregate are not interchangeable measures of the amount of memory available to a model at a given speed.

Price and configuration availability
Lucebox currently advertises the Zero 495 at $5,999; its components page describes the workstation as starting at $5,999. VideoCardz reported direct orders for a $5,999 Ryzen AI MAX+ 395 and Radeon R9700 configuration in September 2026. These sources do not establish that every 128 GB or 192 GB tier carries that price, nor do they guarantee current stock or future pricing. Check the live product listing for the exact processor, memory tier, included components, and delivered price before ordering.
How to interpret the performance claims
Lucebox publishes results for Qwen3.8-27B and DeepSeek V4 Flash on its performance page. In a July 2026 DeepSeek V4 Flash comparison, the company reported median decode rates of 51.1 tokens per second for Lucebox and 14.09 tokens per second for one NVIDIA DGX Spark. Lucebox says the systems used different tuned setups and compression, and characterizes this as a whole-system comparison rather than a controlled GPU-only test. Its test-platform page identifies the benchmark machine as a Ryzen AI MAX+ 395 system with 128 GB, not the advertised 495 configuration.

Notebookcheck’s September 2026 coverage likewise cautioned that the systems used different quantization and test configurations. The figures therefore do not establish a reproducible, identical-settings head-to-head result, and they should not be presented as benchmark performance for the advertised 495 model. Workload performance depends on factors such as model, quantization, context length, software, and whether the reader is comparing prompt processing or token generation.

What to check before buying
- Exact hardware: Ask whether the unit being offered contains the Ryzen AI MAX+ PRO 495 or the 395, and confirm the memory tier in writing.
- Memory accounting: Verify system unified memory and dedicated R9700 memory separately; do not treat a summed capacity as one VRAM pool.
- Workload fit: Look for results using your model, quantization, context length, and software stack. Compare prompt processing and decode behavior separately where possible.
- Software and OS: Check compatibility for the precise operating system and applications you plan to run; AMD’s Windows SDK hardware list is not a blanket compatibility guarantee.
- Purchase terms: Confirm the configuration-specific price, availability, storage and networking, warranty, and support directly with the seller.
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.
