HP Z8 Fury G5 vs Puget Systems Genesis II

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Puget Systems Genesis II comes out ahead by a narrow margin (4.4 vs 4.7). The gap is mostly about Best for enterprise — multi-GPU training and inference — read the strengths below before deciding.

Ranked #4 in Best AI Workstations
HP Z8 Fury G5
$7,995as of Apr 25

The HP Z8 Fury G5 is HP's flagship workstation — a formidable, highly scalable tower designed specifically for demanding professional media, VFX, and AI creators who need a four-GPU ceiling. Built around Intel's Xeon W9-3495X (56 cores), 128 GB DDR5 ECC, and up to four NVIDIA RTX A6000 cards, it is a credible local-LLM training and inference rig at the upper end. The configured price varies enormously: a 1-GPU base build lands around $7,995, a 2-GPU build around $14,000, and a fully loaded 4x RTX A6000 configuration pushes well past $25,000. The price field below reflects a typical 1-GPU configured build; readers planning multi-GPU AI work should expect to roughly triple that figure.

Strengths
  • — Supports up to a four-GPU configuration for extreme parallel AI inference and tensor-parallel training
  • — Features an easily accessible design with a built-in handle for serviceability
  • — Offers a massive range of customization options for specific workloads
Watch-outs
  • — Scaling up configurations becomes prohibitively expensive — 4x A6000 builds push $25,000+
  • — Enormous tower chassis requires significant floor or desk space
  • — Interior uses plain black plastic rather than premium materials

Puget Systems Genesis II
Higher ratedRanked #1 in Best AI Workstations
Puget Systems Genesis II
$10,569as of Apr 25

The Puget Systems Genesis II is a highly customizable, professionally built workstation aimed at enterprise buyers who need bespoke configurations the major OEMs can't match. With AMD Threadripper Pro, up to 4x RTX 4090 (or RTX Ada workstation cards), 256 GB ECC DDR4, and Puget's hand-tuned assembly process, it delivers exceptional performance and build quality with options for a quiet edition. For local LLM work specifically, a single RTX 4090 (24 GB VRAM at 1008 GB/s) handles 70B Q4 with system-RAM offload at roughly 10–20 tokens/sec; a 4x RTX 4090 configuration pools 96 GB of VRAM and easily holds 70B Q4 in VRAM at 30–40 tokens/sec via tensor parallelism. The steep entry price makes this a tool for buyers who can justify a $10K+ workstation — if you only need local LLMs, the DGX Spark below delivers comparable model-size headroom at less than half the price.

Strengths
  • — Highly customizable with a wide assortment of mainstream and pro-channel components like Nvidia Ada workstation GPUs
  • — Serious professional build quality with careful component selection and assembly
  • — Exceptional customer experience including an easy-to-use configuration tool with detailed component comments
Watch-outs
  • — Extremely expensive, with review units costing over $10,000 and configurations reaching nearly $61,000
  • — Configurations with 4x RTX 4090 lose the NVLink that would have helped tensor-parallel LLM inference
  • — Price can be prohibitive compared to a DGX Spark or HP Z6 G5 A for buyers whose only need is local LLMs

How they stack up

HP Z8 Fury G5

Similar to the Dell Precision 7960 Tower, the HP Z8 Fury G5 supports four-GPU configurations for extreme parallel processing, but it differentiates itself with a built-in handle and a design prioritizing easy serviceability. Versus its smaller sibling the HP Z6 G5 A, the Z8 Fury G5 is the right pick when you genuinely need 4 GPUs (versus 3) or the Xeon W9 platform's enterprise ECC and reliability features. Versus the Puget Genesis II, the Z8 Fury G5 brings HP's enterprise service network and parts availability, while Puget brings hand-tuned assembly and a more thoughtful configurator. Versus the Apple Mac Studio M3 Ultra, the Z8 Fury G5 is twice the size and triple the price for a 1-GPU build, but unlocks training-class workloads the Mac Studio cannot touch.

Puget Systems Genesis II

The Puget Systems Genesis II is the enterprise pick. Versus the HP Z8 Fury G5, it offers comparable scale-up capability but in a quieter chassis with a more thoughtful configurator. Versus the HP Z6 G5 A, it's two tiers up in price and ceiling. Versus the NVIDIA DGX Spark, it's a different class of machine entirely — the DGX Spark is a 128 GB unified-memory dev box, the Genesis II is a multi-GPU training/inference workstation. For buyers whose only goal is running large local LLMs, the DGX Spark is the more cost-effective answer; the Genesis II earns its premium when training, fine-tuning, or multi-application workstation duty are part of the picture.
