Our Verdict
HP ZBook Firefly 15 G8 (2021)
Lenovo ThinkPad P1 Gen 4 (2021)
The Lenovo ThinkPad P1 Gen 4 (2021) is much better than the HP ZBook Firefly 15 G8 (2021) as a mobile workstation. The Lenovo is available with more powerful Intel 11th Gen H-series processors and NVIDIA discrete GPUs while being only marginally larger than the HP. The Lenovo's base display configuration is sharper and brighter than the HP's, and its higher-end displays have a wider color gamut for professional color work. The Lenovo doesn't throttle as much under load, but it gets hotter.
