The HP Z8 Fury G5 is a monstrously powerful desktop workstation with a 56-core Intel “Sapphire Rapids” Xeon CPU and four 300-watt graphics cards. There’s no task it can’t handle.

HP Z8 Fury G5 Specifications

The HP Z8 Fury G5 is HP’s premiere desktop workstation, supporting a single Intel Xeon W-class “Sapphire Rapids” processor with up to 56 cores and 2TB of DDR5-4800 ECC memory. Its hallmark feature is supporting four 300-watt double-wide graphics cards. As you’ll see shortly, our unit has the ultimate setup, with four NVIDIA RTX A6000 GPUs. A 2,250-watt power supply (actually two 1,125-watt units) powers the entire setup. This is an unprecedented amount of processing (and electrical) power.

HP is also offering a non-Fury Z8 G5 with two 32-core Xeon CPUs and 1TB of RAM, but it warned us that this is the last time we’ll see dual-CPU workstations. On the Intel side of things, expect dual CPU setups to be reserved for servers only going forward.

You can rightfully expect a workstation of this caliber to be highly configurable. Multi-GPU setups are the Z8 Fury G5’s forte, but HP also advertises up to 120TB of internal storage, so it doesn’t have to be fully GPU-focused. Having four GPUs, like our unit, limits configurability somewhat, as we’ll discuss. For now, here are the Z8 Fury G5’s basic specifications.

HP Z8 Fury G5 Build and Design

The Z8 Fury G5 is an enormous tower at 8.5 x 21.7 x 17.5 inches. Its industrial looks are easy on the eyes and mean all business. Notice all the front-panel airflow perforations. (More on that important topic later.)

HP Z8 Fury G5 Front

The Z8 Fury G5 is built to last; HP puts it through MIL-STD-810H testing, which it passed. The tower is nearly all metal and is rock solid.

The Z8 Fury G5 comes with a standard or premium front panel. Standard-panel ports include 4x USB-A 3.2 Gen 1 (5Gbps), while the premium panel on our unit has 2x USB-A 3.2 Gen 1 and 2x USB-C Gen 2×2 (20Gbps). Both panels have a headset jack. A media card reader is optional.

Our review unit doesn’t have the optional four-bay hot-swap front M.2 drive unit, which is slated for availability later in 2023. It would be an excellent option for quickly transferring data, which is critical considering how much data this system can process. For the next generation, we’d be interested in seeing HP utilize enterprise storage formats, such as E.3S, allowing for much greater capacities and increased durability.

Security is paramount on a high-end workstation like this. The Z8 Fury G5’s physical security features include lockable front access carriers, side panel locks with an interlock sensor, and a Kensington lock slot. The Z8 Fury G5 can also be rack-mounted.

The motherboard’s backplane comes standard with two Gigabit Ethernet ports, with two 10GbE ports available as an option. Faster wired networking than that would require using a PCIe slot, which is a no-go if your system is configured with four GPUs like ours. Wi-Fi 6E and Bluetooth can also be added via PCIe. Other rear ports include 6x USB-A 3.2 Gen 1.

HP Z8 Fury G5 Rear Ports

Our system’s 2,250 watts of power come from two aggregate 1,125-watt power supplies. They’re removable, server-style, as seen here. In Z8 Fury G5 configurations that can operate on a single 1,125-watt power supply, the second one can be used for redundancy.

Both side panels come off for interior access.

HP Z8 Fury G5 Right Panel

All the action is behind the left panel, where you’ll see this technological paradise.

HP Z8 Fury G5 Interior

The four NVIDIA RTX A6000 GPUs are a formidable sight. The cards are double-wide but spaced a nonstandard 2.5 slots apart for improved airflow between the cards.

HP Z8 Fury G5 with Nvidia RTX A6000

Airflow in this tower is front to back; HP “zoned” the chassis, so each GPU, CPU, and DIMM slots effectively have its own air channels.

HP Z8 Fury G5 Cooling

The massive CPU air cooler is responsible for a 350-watt CPU. The 56-core Xeon chip in our unit mandates the premium cooler, which has a vapor chamber and phase-change technology.

HP Z8 Fury G5 CPU Cooler

Sixteen DDR5-4800 ECC DIMM slots flank the CPU, each covered by a cooling shroud.

HP Z8 Fury G5 RAM Cooler

HP Z8 Fury G5 RAM

This tower has 20 sensors and 28 fan speed algorithms to maintain optimal temperatures. The fans can’t be manually controlled beyond cooling profiles in the BIOS. We could still control the GPU’s fans through NVIDIA drivers without going into the BIOS, which is important if you’re running the GPUs full-tilt and want them to maintain their boost clocks.

The Z8 Fury G5 has eight PCIe slots, though, with four double-wide GPUs like our unit, the others are blocked. The three PCIe slots closest to the processor (two immediately above and one below) are Gen5 to avoid the costs of re-drivers.

The motherboard has an integrated HP Anywhere Remote System Controller, which means you don’t sacrifice a PCIe slot for that connectivity. This system controller allows the Z8 Fury G5 to be operated remotely in a data center.

HP Z8 Fury G5 Drive Bays

There are four toolless 3.5-inch expansion bays. HP also offers PCIe cards capable of holding multiple M.2 drives, though to fit them, you can’t have four GPUs. Still, it appears that HP used every inch of this interior for performance or expansion. It’s an impressive machine.

HP Z8 Fury G5 Performance

Our exceptional Z8 Fury G5 review unit has the following specifications:

  • Windows 11 Pro
  • Intel Xeon w9-3945X CPU (56 cores, 112 threads, 4.8GHz Turbo Boost, 350-watt base power)
  • 4x NVIDIA RTX A6000 GPUs
  • 128GB DDR5-4800 ECC RAM (16x 8GB, quad-channel)
  • 2x 1TB Gen4 SSDs (non-RAID)
  • 2250-watt power supply (2x 1,125-watt units)

The Z8 Fury G5 starts at about $5,500. We don’t have exact pricing for our unit, but considering each RTX A6000 graphics card adds about $6,000 (of which, again, we have four!) and the 56-core CPU nearly $10,000, expect it to be over $40,000. Enterprises buying these machines will likely be able to negotiate.

Testing the Z8 Fury G5’s four GPUs proved challenging. Many of our tests wouldn’t run, and several didn’t utilize all its GPUs.

We are comparing the Z8 Fury G5 to the following high-end workstations:

These workstations use AMD’s fastest workstation chip, so at least on the CPU side of things, they’ll make solid comparisons.

Blender OptiX

Blender is an open-source 3D modeling application. This benchmark was run using the Blender Benchmark utility. The score is samples per minute, with higher being better. This test only utilizes one graphics card, so the Z8 Fury G5 didn’t stand apart.

This is a 3D rendering benchmark that supports multiple graphics cards. We only have results for the Z8 Fury G5; below are its results on one, two, and four GPUs.

V-Ray 1 RTX A6000 2x RTX A6000 4x RTX A6000
RTX 2,731 5,357 10,269
CUDA 1,853 3,779 7,491

Previously, we tested V-Ray on the NVIDIA GeForce RTX 3090 and the NVIDIA Quadro RTX 8000 graphics cards, so here are the single GPU comparisons to those cards. The RTX A6000 we’re testing is based on the consumer GeForce RTX 3090, though it has a different memory configuration. (There is a newer RTX A6000 that is identifiable with the “Ada Generation” suffix; we haven’t tested it yet.)

V-Ray HP Z8 Fury G5 (1x RTX A6000) Quadro RTX 8000 GeForce RTX 3090

CUDA 1,853 897 2,025

We also ran V-Ray’s CPU test, where the Z8 Fury G5 scored 46,165.


Next, we look at OctaneBench, a benchmarking utility for OctaneRender, another 3D renderer with RTX support similar to V-Ray. The overall scores are shown, with higher numbers being better. The Z8 Fury G5 dominated with its quad GPUs, as expected.

Blackmagic RAW Speed Test

We have also started running Blackmagic’s RAW speed test, which tests video playback. We only have results for the Z8 Fury G5 and the Precision 7865. The CPU numbers are similar, but the CUDA scores show how much power the HP’s quad RTX A6000s bring to the table.

7-Zip Compression

The built-in memory benchmark in the popular 7-Zip archive tool responds well to faster memory with lower latencies. The Z8 Fury G5 seemed to lag behind the Precision 7865 here, though many variables in the memory configurations prevent an easy explanation. (We only started running this test recently, so we don’t have numbers for the ThinkStation P620.)

Geekbench 6

We ran a few extra benchmarks on the Z8 Fury G5 – after all, it’s not every day we get to test a system this well-equipped. Geekbench 6 is a cross-platform benchmark that measures overall system performance. We only have numbers for the Z8 Fury G5 in this test, but you can find comparisons to any system you want in the Geekbench Browser. Higher scores are better.

What would be a quad-GPU system review without running GPU Pi? See our online result here – the Z8 Fury G5 scored 35 seconds, 126ms, with its quad RTX A6000 setup. Naturally, there aren’t many submissions for similar setups. Our rankings as of this writing are 15th out of 725 World Records, 2nd out of 22 Global Points for 4x GPU setups, and 1st of 1st among 4x RTX A6000s setups!



HP’s Z8 Fury G5 is an absolute monster, with up to a 56-core/112-thread CPU and four double-wide GPUs. Getting more computing power than this would mean stepping up to one or more rackmount servers. Configurability might be the Z8 Fury G5’s best asset; eight PCIe slots allow four GPUs or a combination of GPUs and expansion and/or storage cards. The 2TB memory ceiling is also excellent, as is PCIe Gen5 support on three PCIe slots.

Other features we appreciate about the Z8 Fury G5 are its excellent cooling, comprehensive security (hardware and software), and relatively quiet operation, given the power inside. We also like its built-in remote access controller. We look forward to seeing it become available with the front quad M.2 hot-swap bay.

And this review is just the start. Before we let HP pry this amazing system from our hands, we intend to make it our go-to for AI training and other data science workloads. These tasks are routinely vetted on a workstation before transitioning to a larger GPU training system, so the Z8 Fury G5 should absolutely dance like no one’s watching. Overall, we consider the Z8 Fury G5 the ultimate desktop workstation and award it our “Best of 2023” recommendation.
