We tested the Zbook X2 G4 as it shipped from
HP to ensure we get the same out-of-box experience as our readers, with the latest Windows and HP software updates intstalled. Many variables can affect performance, so our comparisons should serve as a reference point. Our benchmarking kicks off with storage, CPU, and GPU tests to get an idea how the Zbook X2 G4 performs in day-to-day tasks for these high-level subsystems.

ATTO Disk Benchmark
|
Peak Sequential Storage Throughput
|
|
The ATTO disk benchmark gives us a quick look at how snappy the HP Zbook X2 G4 should feel for basic, storage-bound tasks such as Windows startup and app loading. HP doesn’t skimp in the storage department and installs a fast Samsung SM960 SSD in the Zbook X2 G4. The PCIe x4 SSD promises 3200 MB/s and 1700 MB/s read and write speeds.
ATTO reveals what we expected, the Samsung SM961 is a fast SSD and saw peak read speeds of 3300 MB/s with 1600 MB/s writes. This shows in everyday use as the HP Zbook X2 G4 is very snappy and loads apps quickly and painlessly.

Cinebench R15
|
3D Rendering On The CPU And GPU
|
|
Cinebench tests the CPU and GPU independently and provides a glimpse of raw performance. The test is based on Maxon’s Cinema 4D modeling software that’s used in movie productions.
CPU performance is somewhat disappointing with the Zbook X2 G4 trailing the
Dell Latitude 7390, which shares the same Core i7-8650U processor, by 8-percent. We speculate the thermal constraints of the thinner form factor of the Zbook X2 G4 makes it unable to maintain peak Turbo Boost speeds as long.
Nevertheless, the Zbook X2 G4 redeems itself thanks to the Quadro GPU in OpenGL performance. Here we see the Quadro M620 put up a good fight against the more powerful Dell XPS 15 2-in-1 with its RX Vega M graphics. It delivers over twice the OpenGL performance of anything with Intel HD 620 and the Radeon Vega 8 in the Ryzen 5 2500U thanks to the workstation-optimized Quadro drivers.

Geekbench 4
|
Single and multi-core
|
|
Geekbench 4 is a cross-platform benchmark that simulates real world processing workloads in image processing and particle physics scenarios. We tested the HP Zbook X2 G4 in Geekbench 4’s single and multi-core test workloads.
While the Zbook X2 G4 didn’t quite shine in Cinebench R15, it came back with a vengeance in Geekbench 4. Here it manages to outperform everything else we’ve tested, including the Dell XPS 15 2-in-1.
