HP Inc B28G0UA#ABA HP Z8G5 W3465X 128GB/1TB PC United States / Canada English
Overview
The HP Z8 G5 is a tower workstation built on an Intel Xeon W7-3465X processor (up to 4.8 GHz with Intel Turbo Boost Technology, 75 MB L3 cache, 28 cores, 56 threads) paired with 128 GB of DDR5-4800 MT/s memory across 8 x 16 GB modules, on an Intel W790 chipset with 16 DIMM slots. Storage is configured with a 2 TB PCIe NVMe TLC M.2 SSD and a 1 TB HP Z Turbo Drive PCIe Gen4 TLC M.2 SSD, and the system ships with Windows 11 Pro.
Graphics are handled by an NVIDIA RTX 6000 Ada Generation card with 48 GB of dedicated GDDR6 memory. The chassis provides extensive internal expansion with six PCIe M.2 SSD bays and six 3.5-inch HDD bays internally, plus four external NVMe M.2 SSD bays, two external 3.5-inch HDD bays, and two 9.5 mm ODD bays, backed by a 1125 W internal power supply rated up to 90% efficiency with active PFC.
Key Features
- Intel Xeon W7-3465X Processor: 28 cores and 56 threads clock up to 4.8 GHz with Intel Turbo Boost Technology, backed by 75 MB of L3 cache and the Intel W790 chipset — built for heavily threaded engineering, simulation, and data science workloads.
- 128 GB DDR5-4800 Memory: Eight 16 GB DDR5-4800 MT/s modules populate the 16-DIMM-slot motherboard, giving large datasets and multitasking workflows substantial headroom.
- NVIDIA RTX 6000 Ada Generation Graphics: 48 GB of dedicated GDDR6 memory supports professional visualization work including CAD/BIM, 3D modeling and rendering, and simulation.
- Dual NVMe SSD Storage: A 2 TB PCIe NVMe TLC M.2 SSD pairs with a 1 TB HP Z Turbo Drive PCIe Gen4 TLC M.2 SSD for fast boot and working-data performance.
- Extensive Expansion Capacity: Internal bays for six PCIe M.2 SSDs and six 3.5-inch HDDs are joined by external bays for four NVMe M.2 SSDs, two 3.5-inch HDDs, and two 9.5 mm ODDs, with seven PCIe slots (including 2 PCIe 5 x16 and 2 PCIe 4 x16) for additional cards.
- Enterprise Security Stack: Full volume encryption, TPM 2.0 certification, Kensington lock slot, Self-Encrypted Drives, and the HP Sure suite (Sure Run, Sure Click, Sure Sense, Sure Admin, Sure Start, Sure Recover) protect data and firmware integrity.
- 1125 W High-Efficiency Power Supply: An internal power supply rated up to 90% efficiency with active PFC delivers stable power for high-core-count CPUs and workstation-class GPUs.
Integration and Compatibility
The HP Z8 G5 includes integrated SATA 6.0 Gb/s storage control with RAID 0 and 1 available for SATA drives, plus front premium I/O port placement with 4 USB Type-A ports at 5Gbps signaling rate and a headphone/microphone combo jack for convenient workstation access.

The HP BIOSphere and HP Platform Certificate round out firmware-level management and security for IT administrators deploying at scale.
Frequently Asked Questions
Q: What processor does the HP Z8 G5 (B28G0UA#ABA) use?
A: It uses an Intel Xeon W7-3465X processor with 28 cores, 56 threads, clock speeds up to 4.8 GHz with Intel Turbo Boost Technology, and 75 MB of L3 cache, on the Intel W790 chipset.
Q: How much memory and storage does this configuration include?
A: It includes 128 GB of DDR5-4800 MT/s memory (8 x 16 GB) across 16 DIMM slots, plus a 2 TB PCIe NVMe TLC M.2 SSD and a 1 TB HP Z Turbo Drive PCIe Gen4 TLC M.2 SSD.
Q: What graphics card is installed?
A: An NVIDIA RTX 6000 Ada Generation card with 48 GB of dedicated GDDR6 memory.
Q: What operating system ships on this unit?
A: Windows 11 Pro.
Q: What expansion options does the Z8 G5 chassis offer?
A: The tower chassis offers six internal PCIe M.2 SSD bays, six internal 3.5-inch HDD bays, four external NVMe M.2 SSD bays, two external 3.5-inch HDD bays, two external 9.5 mm ODD bays, and seven PCIe expansion slots in a mix of PCIe 3, 4, and 5 configurations.
This Z8 G5 configuration pairs a 28-core Xeon W7-3465X with 128 GB of DDR5 memory and an RTX 6000 Ada Generation GPU with 48 GB of dedicated memory — a combination that matters for anyone running large assemblies, simulation datasets, or memory-hungry rendering jobs where both CPU threading and GPU memory capacity become limiting factors.
Technical Highlights:
- Thread count for parallel workloads: 56 threads across 28 cores gives simulation, rendering, and data science jobs substantial parallel headroom without needing a dual-socket system.
- 48 GB GPU memory capacity: The RTX 6000 Ada Generation's 48 GB of dedicated GDDR6 is the detail to watch for teams working with large 3D scenes or models that exceed typical workstation GPU memory limits.
- Six-bay internal storage runway: With six internal PCIe M.2 bays and six internal 3.5-inch HDD bays beyond the installed 2 TB and 1 TB drives, this chassis has real room to grow storage without external enclosures.
Deployment Considerations:
- The 1125 W power supply and extensive bay count point to a full tower deployment — confirm rack or desk-side space and power circuit requirements before installation.
- Expansion slot access varies: 2 of the PCIe 4 x8 slots are internal-access only for M.2 and not reachable from the rear bulkhead, which matters when planning card layouts.
This configuration suits engineering, simulation, and data science teams whose workloads benefit from high core counts and large GPU memory capacity in a single-socket tower.
