Verdict: A Platform Built for AI First, CAD Second
The Intel Xeon 658X and HP Z8 Fury G6i form a high‑end professional workstation platform that combines a 24‑core Granite Rapids‑WS CPU, fast DDR5‑6400 memory, and dense Blackwell GPU options to accelerate real‑world AI inference, 3D rendering, and professional CAD workloads for teams that need guaranteed ISV certification and predictable multi‑GPU scaling. This combo is excellent but unapologetically expensive: the Xeon 658X itself sells for roughly USD 2,000 to 2,300 (approx. RM9,200–RM10,600), while the HP Z8 Fury G6i tower starts around USD 7,900 (approx. RM36,300) and can reach USD 52,139 (approx. RM239,800) in heavy configurations. At those prices, it stops being a “nice workstation” and becomes an infrastructure decision. My bottom line: it is worth it for AI and GPU‑heavy pipelines that can keep all those PCIe lanes busy, but overshoot for lighter CAD or mixed‑office work.
| Spec | Xeon 658X platform | HP Z8 Fury G6i tower |
|---|---|---|
| CPU options | Xeon 658X: 24C/48T, 3.0GHz base, 4.9GHz turbo, 144MB cache, 250W base TDP | Up to Xeon 698X: 86C/172T, 2.0GHz base, 4.8GHz turbo, 336MB cache, 350W |
| Memory | Up to 4TB across 8 DDR5-6400 channels | 16 DIMM slots, up to 2TB DDR5-6400 ECC |
| PCIe lanes / slots | 128 PCIe 5.0 lanes from CPU | 9 slots: 4× PCIe 5 x16, 3× PCIe 5 x8, 1× PCIe 5 x4, 1× PCIe 4 x4 |
| GPU support | Multi‑GPU via workstation W890 boards | Up to 4× RTX PRO 6000 Blackwell Max‑Q (300W) or 1× 600W RTX PRO 6000 |
| Storage | Tested with 1TB PCIe SSD; platform supports many NVMe devices | Up to 104TB, 8 internal M.2 NVMe, 4 front hot‑swap NVMe bays |
Intel Xeon 658X: Platform Power Over Core Count
The Xeon 658X is a 24‑core, 48‑thread professional workstation CPU aimed at users who care more about memory bandwidth, PCIe connectivity, and instruction support than raw core counts. It runs at 3.0GHz base and up to 4.9GHz turbo, with 144MB of cache and a 250W base power that can climb to 300W under full turbo. Crucially, it keeps the same 128 PCIe 5.0 lanes and eight DDR5‑6400 memory channels as the 64‑ and 86‑core models, plus AMX and AVX‑512 acceleration. In other words, you give up cores but keep the full Granite Rapids‑WS platform. In CPU rendering with Blender, the Xeon 658X test platform landed in the middle of the pack: for the Monster scene, it reached 365.315 samples per minute versus 694.751 on the Xeon 696X‑powered HP Z8 Fury G6i and 1039.121 on the Threadripper PRO workstation. That makes the 658X more about balanced single‑socket work than about record‑breaking renders.
HP Z8 Fury G6i: Multi‑GPU Muscle and AI‑First Design
The HP Z8 Fury G6i is a large, matte‑black tower built specifically around the Xeon 600 series on the W890 chipset for AI workstation duties rather than classical CAD alone. It starts at 48.9 lb and roughly 17.5 × 8.6 × 22 inches, with a full‑height diamond‑mesh front grille, collapsible rear handle, and internal bracing for dual‑PSU and multi‑GPU layouts. Inside, you can configure it from an 18‑core Xeon 654 up to the 86‑core Xeon 698X, with the Xeon 658X available as one of the performance‑focused mid‑stack options. A standout feature is GPU density: four PCIe 5.0 x16 slots allow up to four NVIDIA RTX PRO 6000 Blackwell Max‑Q Workstation Edition GPUs (300W each) for 384GB of combined VRAM, or a single 600W RTX PRO 6000 if peak single‑card Blackwell GPU performance is the priority. Coupled with up to 2TB of DDR5‑6400 ECC and support for eight internal M.2 NVMe devices and 104TB total storage, it squarely targets AI rendering workloads and heavy GPU inference pipelines.
Real‑World Performance: AI Inference, Rendering, and CAD
Both the bare Xeon 658X platform and the HP Z8 Fury G6i were tested across AI inference, 3D rendering, and workstation‑class CPU benchmarks. In the Procyon AI Computer Vision CPU test, the Xeon 658X platform scored 248, beating the Z8 Fury G6i’s 207 and an AMD‑based workstation at 157, making it around 20% faster than the HP system and roughly 58% ahead of the AMD machine in this specific CPU inference scenario. At the same time, the HP Z8 Fury G6i’s higher‑core Xeon 696X showed clear advantages in Blender CPU rendering: its Monster result of 694.751 samples per minute is about 90% higher than the 365.315 samples per minute of the Xeon 658X platform, while the 96‑core AMD rival still leads. The takeaway is plain: if your workloads are heavily multi‑threaded renders or simulations, more cores pay off; if they are AI inference tasks that lean on AMX/AVX‑512 and fast memory, the 658X offers strong value as a professional workstation CPU.
Buy if / Skip if
- Buy the Intel Xeon 658X and HP Z8 Fury G6i platform if your primary workloads are AI inference and GPU‑accelerated AI rendering that can exploit 128 PCIe 5.0 lanes and multiple RTX PRO 6000 Blackwell GPUs.
- Skip the Intel Xeon 658X and HP Z8 Fury G6i platform if your team mainly does light CAD, office productivity, or modest 3D scenes that will never saturate dozens of cores or more than one GPU.
- Buy the Intel Xeon 658X and HP Z8 Fury G6i platform if you need ISV‑certified professional applications, up to 2TB of DDR5‑6400 ECC memory, and centralised rack‑mount deployment options in a 5RU form factor.
- Skip the Intel Xeon 658X and HP Z8 Fury G6i platform if your budget cannot justify workstation hardware starting at about USD 7,900 (approx. RM36,300) for the tower and around USD 2,000–2,300 (approx. RM9,200–RM10,600) for the CPU alone.
- Buy the Intel Xeon 658X and HP Z8 Fury G6i platform if you want a long‑life single‑socket workstation that balances strong AI scores with enough cores for mixed workloads, without going to 64‑ or 86‑core extremes.
