Ultrabook workstations – this sounds like an oxymoron, but this category of rather inexpensive, thin mobile workstations with ULV processors (TDP of 15 watts) has been available for years. Up until ULV processors with four cores became mainstream, devices of this type were hardly of any use for more demanding tasks. Nowadays, they can partially keep up with older “full-grown” workstations.
HP also seems to think that the category has potential. At any rate, that would explain why HP ZBook branded ultrabook workstations have been given a new, more marketable name in this edition. The HP ZBook Firefly 15 G7 7 is the successor to the HP ZBook 15u G6 and comes with more recent Intel Comet Lake CPUs, the Nvidia Quadro P520, 32 GB of RAM, a 1 TB SSD, and a 4K UHD display. This is the best configuration available, and it costs around 2,100 Euros (~$2,460).
Besides its direct predecessor, we also compare the ZBook Firefly with the Lenovo ThinkPad P53s, an ultrabook workstation from last year. The Dell Precision 5550, which has an ultrabook form factor but uses Intel Comet Lake H CPUs with more cores, serves as another comparison device.
