For most of the last decade, the high-core workstation conversation has been largely led by AMD. Threadripper PRO pushed core counts, cache, and PCIe lanes past what Intel’s Xeon-W line could offer; the prior Xeon-W flagship topped out at 60 cores, while AMD kept climbing. Intel’s Xeon 600 series, launched in February of this year, is the first CPU in years built to take that argument back, reaching 86 cores on the Granite Rapids-WS platform with 128 PCIe 5.0 lanes. The HP Z8 Fury G6i is the system HP built around it.
HP frames the Z8 Fury G6i as an AI workstation rather than a CAD tower, which aligns with current industry trends. One Xeon 600 processor pairs with up to four NVIDIA RTX PRO 6000 Blackwell Max-Q Workstation Edition GPUs (300-watt) for 384 GB of aggregate VRAM, or a single 600W RTX PRO 6000 Workstation Edition for peak single-card performance. The platform supports up to 2 TB of DDR5-6400 ECC memory across eight channels, four M.2 drive slots (with options for more), and up to nine PCIe slots in a roughly 54-liter tower. HP also offers a rack mounting kit (5RU), so a team can centralize it, should the use case dictate.
Our review unit sits one rung below the top of the stack. It runs the 64-core Xeon 696X with two RTX PRO 6000 Max-Q cards for 192 GB of combined VRAM, 128 GB of DDR5-6400, and a four-drive NVMe layout that separates a fast Gen5 boot volume from three Gen4 data drives. That configuration frames the question this review works through: how a single high-core Xeon and a dense Blackwell GPU config balance against each other across professional graphics, GPU rendering, and AI inference, and where the platform gives ground.
The Z8 Fury G6i is configurable on the HP website and starts at roughly $7900 at the time of this review. Our configuration comes in at $52,139. It’s worth noting that most of these systems are bought through corporate acquisition, and volume pricing will be better.

Design and Build
The Z8 Fury G6i carries over the look HP has settled on across its latest workstation lineup, with a uniform matte black finish from the chassis to the front fascia. The face is dominated by a plastic diamond-mesh grille that runs the full height of the tower for airflow, broken only by the front I/O strip near the top and the metallic HP logo lower down. The tower itself is substantial: it starts at 48.9 lb and measures 17.5 x 8.6 x 22 inches without the rear handle, growing to 17.5 x 10 x 22 inches with the maximum side panel fitted. That heft is a function of the dual-PSU, multi-GPU support built inside, but the result is a rigid, well-damped enclosure that feels every bit the professional-grade workstation it is.
Storage
For boot and high-speed flash storage, the Z8 Fury G6i provides four onboard PCIe Gen5 M.2 slots (labeled SSD0 through SSD3), each fitted with a finned heatsink and a tool-free blue latch for retention. HP sells the drives in 1, 2, 4, and 8TB capacities, so the four slots can be populated to suit anything from a single boot drive to a high-capacity NVMe array.
For bulk storage, the Z8 Fury G6i includes two internal 3.5-inch drive bays with tool-free carriers, letting you slot in high-capacity HDDs without a screwdriver. The bays sit on a backplane with the SATA/power connectors fixed in place, so drives seat directly as they slide in.
I/O and Expansion
The Z8 Fury G6i has a fairly standard set of I/O ports for workstations, with four USB Type-A 5 Gbps ports (one charging) and a single 3.5 mm headphone/microphone combo port. HP, however, offers a premium front I/O setup with two USB Type-A 5 Gbps ports (one charging), two USB Type-C 20 Gbps ports (both charging), and a 3.5 mm headphone/microphone combo port. Both front I/O configurations also offer an SD card reader alongside the I/O ports. Our review unit included the premium front I/O package.
On the rear of the Z8, we again see a fairly standard I/O setup with an integrated GbE Ethernet port, five USB Type-A 5 Gbps ports, a single USB Type-C 10 Gbps port, and another headphone/microphone combination port. Near our standard I/O ports, we also see the Flex I/O port, which offers up to 10GBASE-T or 2 Thunderbolt 5 ports. Also on the rear is a collapsible handle that folds flush against the chassis when not in use, but pops out to provide a sturdy hold point for lifting or repositioning the workstation.
When it comes to expansion slots, the Z8 Fury G6i has a total of 9 PCIe slots: 4 PCIe 5 x16, 3 PCIe 5 x8, 1 PCIe 5 x4, and 1 PCIe 4 x4. These four PCIe 5 x16 slots are what allow the Z8 to house the quad NVIDIA RTX PRO 6000 Blackwell Max-Q cards in a fully loaded configuration.
The board also exposes a dedicated network MCIO connector that accepts an optional add-in module for 2x 10GbE or 2x 25GbE LANs. Our review unit shipped without the module, leaving the slot open, but it’s the path HP provides for adding higher-speed networking without consuming a standard PCIe expansion slot.
HP pairs a tool-free PCIe retention latch at the top slot with a pivoting bar that swings to release the card, so the top GPU disengages cleanly without fighting the PCIe slot lock.
We can also see to the left of the chassis the dual removable power supplies that can be configured in either a redundant or cumulative configuration, totaling up to 2700W, to feed configurations like the highest spec buildout that contains a 350W TDP CPU and up to 1200W of GPUs, being either a single RTX PRO 6000 Blackwell card or 4x RTX Pro 6000 Blackwell Max-Q (300W). The power supply setup is unique in that it can support high-end configurations that would exceed what a 15-A or 20-A 120V circuit can handle on its own, before requiring a move to a 240V circuit. For areas that could supply two discrete 120V circuits, you can run the hardware in that environment off this dual-PSU configuration

HP Z8 Fury G6i vLLM Performance Testing
To evaluate the HP Z8 Fury G6i, we tested configurations using the vLLM Online Serving benchmark, one of the most widely adopted high-throughput inference and serving engines for large language models. The vLLM online serving benchmark simulates real-world production workloads by sending concurrent requests to a running vLLM server and measuring key metrics, including total token throughput (tokens per second), time to first token, and time per output token, under varying load conditions.
Our testing spanned a range of models, from dense architectures to micro-scaling data types. The tests evaluated performance across three workload scenarios: Equal ISL/OSL, Prefill Heavy, and Decode Heavy. These scenarios represent distinct real-world serving patterns, from balanced input and output loads to compute-intensive prompt processing and memory-bandwidth-bound token generation.
To benchmark the HP Z8 Fury G6i, we tested a dual-GPU configuration (2x NVIDIA RTX PRO 6000 Blackwell). Because the system was tested with the same NVIDIA RTX PRO 6000 Blackwell cards used in our Dell Precision 7875 review, the results provide a direct platform-to-platform comparison between the two workstations.

Platform Differences: Why the HP Pulls Ahead
Both workstations run identical 2x RTX PRO 6000 Blackwell GPUs, and neither platform supports NVLink, so all inter-GPU communication during tensor-parallel inference travels over PCIe. The Dell Precision 7875 has one PCIe Gen 5 x16 slot with the second GPU running at Gen 4 x16, while the HP Z8 Fury G6i provides full PCIe Gen 5 x16 to all GPU slots.
The host CPU also plays a role since vLLM’s scheduler and token processing run on the CPU rather than the GPU, and the Intel Xeon 6 platform in the HP offers architectural advantages that the Threadripper PRO does not. These platform differences are most pronounced on smaller and quantized models at high concurrency, where the HP leads by 30-37%, and shrink to the low single digits on large MoE models like GPT-OSS-120B, where GPU compute time is the dominant factor.
Conclusion
The HP Z8 Fury G6i is HP’s statement that Intel is back in the high-core workstation conversation. Built around the Granite Rapids-WS Xeon 600 series, our review unit paired the 64-core Xeon 696X with two NVIDIA RTX PRO 6000 Blackwell Max-Q cards, 128 GB of DDR5-6400, and a four-drive NVMe layout, positioning it squarely as an AI workstation rather than a traditional CAD tower. The build reflects HP’s current design language: a uniform matte black chassis with a full-height diamond-mesh grille, paired with a genuinely serviceable interior featuring tool-free NVMe latches, removable dual power supplies, a collapsible rear handle, and a nine-slot, four-PCIe-Gen5-x16 layout that scales to four Max-Q cards.
In our benchmarks, the Z8 Fury staked out clear wins where its platform strengths matter. It dominated the Blackmagic RAW Speed Test at 311 FPS (8K CPU) and 650 FPS (GPU), topped the field in 7-Zip compression at 344.96 GIPS, led the smaller Y-Cruncher datasets, and posted strong SPECworkstation 4.0 results that outpaced the Intel Xeon 658x platform across nearly every vertical. GPU rendering in Blender and LuxMark was effectively a tie with the Dell Precision 7875, as expected given the shared RTX PRO 6000 silicon.
Where it gives ground, the pattern is consistent. The 96-core Threadripper PRO in the Dell still leads in heavily multithreaded and memory-bound workloads, including Blender CPU, the larger Y-Cruncher runs, 3DMark CPU, and several Topaz Video AI models, reflecting its higher core count and 512 GB of memory. The vLLM inference results are where the platform argument gets interesting: running identical dual RTX PRO 6000 cards, the HP pulled ahead by 30 to 40 percent on smaller and quantized models at high concurrency, narrowing to low single digits on large MoE models like GPT-OSS-120B, where GPU compute dominates. With neither platform supporting NVLink, that gap traces back to HP’s full PCIe Gen5 x16 to every GPU slot and the Xeon 6 host handling vLLM’s CPU-side scheduling more effectively than the Threadripper PRO.
At $52,139 as configured, the Z8 Fury G6i is a serious investment, though most buyers will see better volume pricing through corporate channels. What you get is a thoroughly engineered, highly serviceable AI workstation that, depending on workload, trades blows with the best Threadripper PRO towers and pulls clearly ahead in PCIe-bound multi-GPU inference. For organizations standardizing on Intel and prioritizing GPU-accelerated AI work, the HP Z8 Fury G6i makes a strong case for itself.
