HP ZGX Fury Specs: 748 GB GB300 Tower, No US Price, 200-240 V

The HP ZGX Fury AI Station, a GB300 tower with 748 GB of memory, needs a dedicated 200–240 V AC circuit and will not run from a standard 120 V household outlet, HP's US product page says.

HP opened orders on Sept. 9 and its US page still shows no price. The only list price is in Japan: HP Japan announced the ZGX Fury G1n on Oct. 26 and began sales on Oct. 27, from 28,490,000 yen including tax. Our Nov. 1 DGX Station review already covered that price and the platform's two-tower cluster test. This piece sets out what HP's own pages add, what the one lab run shows about the HP unit, and what is still missing. We found no published measurement of a single ZGX Fury, so this is not a review, and Voltgrid did not test the machine.

HP ZGX Fury Specs: What HP's Page Lists

The silicon is NVIDIA's DGX Station design. HP lists a 72-core NVIDIA Grace Neoverse V2 CPU, soldered to the board, with four 128 GB SOCAMM modules of LPDDR5x: 496 GB at 396 GB/s. The Blackwell Ultra GPU carries 252 GB of HBM3e at 7.1 TB/s. HP adds the two pools and calls the result 748 GB of unified memory, and it rates the GB300 at up to 20 petaFLOPS FP4, a figure HP does not label as sparse or dense; NVIDIA's DGX Station table gives 20 with sparsity and 15 without.

Storage is split in two. Two M.2 drives on PCIe Gen5 hang off the CPU and hold the operating system as a software RAID 1 mirror. Two more on PCIe Gen6 come off the ConnectX-8 network card and form a software RAID 0 data volume, HP says. StorageReview reported on Sept. 9 that the data drives are 2 TB or 4 TB self-encrypting NVMe, chosen at purchase. That is the Gen5-plus-Gen6 layout ASUS lists for its ET900N G3, not the four Gen5 slots on NVIDIA's own listing.

The box is built for a rack as much as a desk. It runs as a tower or in a standard 5U rack slot on included rails, HP says, with liquid cooling and front-to-back airflow so that racking it does not block ventilation. The ConnectX-8 brings two QSFP112 ports at 400 Gbps each for linking a second unit, plus a 10 Gbps RJ-45 port and a separate management controller with its own 1 Gbps port. Power enters through a C20 inlet. The GB300 drives no monitor itself; HP offers an optional NVIDIA RTX PRO card for displays, StorageReview reported.

Software is Linux first. The ZGX Fury ships with Ubuntu 24.04 LTS, NVIDIA's AI developer tools and two HP layers: Z Runtime, a preinstalled command-line tool that pulls and serves models, and Z Toolkit, a free VS Code extension. In its Sept. 9 release, HP said the machine is certified for Red Hat Enterprise Linux. A Red Hat AI Factory with NVIDIA platform on the Fury is planned, with timing and supported configurations still to be announced.

What the 20 PFLOPS FP4 Rating Means

HP rates the ZGX Fury at up to 20 petaFLOPS of FP4 and puts no sparsity label on that figure. Structured sparsity lets hardware skip half the weights in a matrix, so vendors that count it quote twice the dense rate. NVIDIA's table for its DGX Station lists 20 PFLOPS of FP4 with sparsity and 15 without.

A peak rating is not a speed. Local inference is usually limited by how fast weights stream from memory, and the Fury has two tiers: 252 GB of HBM3e at 7.1 TB/s and 496 GB of LPDDR5x at 396 GB/s, HP says. StorageReview's 5,018 tokens per second came from two towers running one model, not from the 20 petaFLOPS rating.

What Models the ZGX Fury Can Hold

HP pitches the ZGX Fury as a shared machine for a team, not a personal PC. It says the Fury hosts models of up to 1 trillion parameters and fine-tunes models up to the 100-billion-parameter class, with a footnote that its model harness quantizes at FP4. The ZGX Nano has 128 GB at 273 GB/s; HP's own FAQ says teams prototype on the Nano and move the same workflow to the Fury for larger models, more throughput and more users.

The memory split sets the speed. A model that fits in the 252 GB of HBM3e reads its weights at 7.1 TB/s. Anything larger spills into the LPDDR5x at 396 GB/s, about an eighteenth of that rate by Voltgrid's arithmetic on HP's two figures; HP states no ratio. The 748 GB decides which models load at all; the 252 GB decides which stay fast.

What the Only Lab Data Shows

The one independent measurement involving the HP is a cluster run. StorageReview, on Oct. 5, linked an ASUS ET900N G3 and a ZGX Fury with two 400G direct-attach copper cables. GPUDirect RDMA reached 392 Gb/s on each rail, and NCCL collectives hit 98 GB/s on broadcast, reduce and send/receive. With GLM-5.3 in NVFP4 split across both GPUs under vLLM 0.27.1, the pair reached 5,018 output tokens per second at 256 streams, against 188 at 32 streams on one tower. The two points are not a like-for-like multiple, because the stream counts differ, and the split used tensor parallelism with an MTP draft setting that StorageReview chose.

The HP had its own job in one test. For GLM-5.3 Flash, the ASUS processed the prompts and the HP generated the tokens. With 512-token prompts and answers on vLLM 0.28.1 RC1, output at 32 streams rose from 828 tokens per second on one Station to 2,721 on the pair. Each point was a single pass. The single-tower baseline in every chart was the ASUS, so none of these figures is a solo HP result, and they say nothing about HP's cooling, clocks or noise.

What Is Still Unknown

There is no US, UK or EU list price. HP's Oct. 7 release told buyers of the Windows version to contact a local sales representative. For scale, Dell.com listed its GB300 tower at $160,195 in its default configuration with an RTX PRO 2000, and Central Computers listed the ASUS from $111,999.99 as a quote-only build with two 2 TB drives, but the builds differ and neither figure says anything about HP's price.

HP's page gives no power supply rating, weight, dimensions or noise level; it refers buyers to the QuickSpecs for full power specifications. NVIDIA rates the platform at 1,600 W of total system power on a 20 A circuit, and no lab has measured an HP unit at the wall.

Windows is planned, not shipping. HP first showed Windows running on the ZGX Fury at a Microsoft event on Oct. 7, and HP Japan says Windows support is planned from December 2026. StorageReview notes that whether serving stacks will run natively on Windows or under WSL is still open.

StorageReview's desktop ranking page says the ZGX Fury is in its lab and the solo review is under way, and that it will rank the machine once its own bench numbers are in. The page gives no date for that statement. That review, a US price and the December Windows release are the next milestones.
