01Compute platform

AMD Ryzen AI MAX+ PRO 495 with up to 192 GB of unified memory

The Ryzen AI MAX+ PRO 495 shares 128 GB or 192 GB of LPDDR5X-8533 between the CPU and its 40-core Radeon 8065S integrated GPU at 273 GB/s. Models that do not fit in 32 GB of VRAM run here: long context, MoE models such as DeepSeek V4 Flash, or a second model kept resident while the R9700 serves the hot path.

Memory	128 GB or 192 GB LPDDR5X-8533, shared by CPU and integrated GPU
Bandwidth	273 GB/s
Integrated GPU	Radeon 8065S, 40 compute units
Processor	AMD Ryzen AI MAX+ PRO 495, 16 cores / 32 threads
Role	Large models, long context, and the second resident model

02Dedicated GPU

AMD Radeon AI PRO R9700

The only discrete GPU in the production configuration. 32 GB of GDDR6 at 640 GB/s keeps the weights and KV cache of a 27B-class model on the card, which is where the engine’s custom kernels and DFlash speculative decoding run.

Memory	32 GB GDDR6
Bandwidth	640 GB/s
Compute	64 compute units, up to 191 TFLOPS at FP16
Board power	Up to 300 W under sustained inference
Interface	PCIe 4.0 through an M.2 NVMe to x16 riser on the compute board

03Enclosure

Extruded aluminium chassis, anodized black

Every chassis is extruded aluminium, anodized black, and hand-assembled in-house. At 11.97 litres it holds a full-length workstation GPU, the compute board, and an SFX power supply in a box that fits a shelf or a rack area.

Enclosure	Extruded aluminium, anodized black, hand-assembled in-house
Dimensions	340 × 110 × 320 mm (13.4 × 4.3 × 12.6 in)
Volume	11.97 L (approximately 730 in³)
Weight	6 kg (13.2 lb)
Finish	Anodized black

04Cooling and thermals

Two air paths, exhaust out the back

A 120 mm fan cools the compute region and the R9700 runs its own cooler, each with an independent airflow path that exits through the rear. Quiet at idle; the GPU becomes audible during sustained inference, which is why most people keep Lucebox out of earshot and reach it over the network.

Cooling	Air-cooled, tuned for low noise under sustained load
Compute region	120 mm top fan over the compute board
GPU	R9700 cooler on its own airflow path
Exhaust	Hot air leaves through the back of the chassis
Acoustics	Quiet at idle, GPU cooling audible under sustained inference
