Sporting a pair of Intel Xeon E5-2667 v3 processors, HP’s Z640 offers 32 virtual cores with Hyper-Threading enabled. HP’s processors are fast, with a nominal frequency of 3.2GHz, boosting to 3.6GHz in Turbo Boost.
HP has installed 64GB of 2,133MHz DIMMs. Surprisingly, the manufacturer hasn’t opted for a top-of-the-range graphics card: the PNY Quadro K4200 is no slouch, but a K5200 would have been better.
The model uses a conventional SATA SSD as primary storage. The 512GB capacity is generous, but performance is way behind the M.2 drives in the Armari and Apple entries.
Strangely, HP has opted for a 15,000rpm SATA disk with only 300GB of capacity.
This is the quickest non-SSD on test, but it won’t be enough space if you’re planning to work with large amounts of video, particularly 4K. However, HP has created a tool-free chassis design that will make it easy to add storage further down the line.
The HP Z640 is a super-powerful workstation, but it’s on the pricey side. It’s great for tasks such as rendering that can take full advantage of the many cores available, and it would also be great for photo and video editing.
