You will hardly use this screen position in practice, so this is not a deal-breaker. At an angle of 25 degrees or lower, however, the lid closes automatically. The two hinges allow a maximum opening angle of 180 degrees and are well adjusted, because there is hardly any bouncing. Like previous ThinkPad models, the P1 G4 meets the MIL-STD-810H requirements, but Lenovo does not list the individual tests. The stability is still excellent and neither the base unit, nor the lid can be noticeable twisted or dented and there are no creaking sounds. You can quickly see fingerprints and similar to other ThinkPads, we expect there will be greasy spots. The materials are pretty much the same and you still get smooth plastic surfaces with metallic or hybrid materials underneath. The new power button, which also includes the fingerprint scanner, is slightly shifted upwards. When you open the lid, however, you immediately notice the new 16:10 screen with narrower bezels and the new speaker grilles next to the keyboard. Looking at the chassis, you will have a hard time to distinguish the new ThinkPad P1 G4 from its predecessors. We did, however, notice an improvement in PCMark 10, but the advantage was very small (up to 5% depending on the sub-test) and therefore negligible.
As expected, the pure CPU performance did not improve since the cooling solution is the limiting factor.
X1 EXTREME DOCKSTATION UPDATE
Update : We retested some of the CPU benchmarks with an additional RAM module (16 GB DDR4-3200). Our test unit of the ThinkPad P1 G4 is an entry-level model with the designation 20Y30017GE for about 2400 Euros is equipped with the new 16-inch display and the WQHD resolution (2560 x 1600 pixels), the Core i7-11800H, the new Nvidia T1200 GPU), and a fast PCIe 4.0 SSD with a storage capacity of 512 GB. This cooling solution requires more space though, so there is only one M.2-2280 slot and you cannot equip them with a WWAN module. Lenovo offers two basic models of the ThinkPad P1 G4 (also applies for the X1 Extreme G4), because depending on the graphics card, you either get a traditional cooling solution (with the Nvidia T1200 & RTX A2000 in the P1 G4 or RTX 3050 Ti in the X1 Extreme G4) or a vapor chamber cooling in combination with more powerful graphics cards.
X1 EXTREME DOCKSTATION PROFESSIONAL
In addition to new Tiger Lake-H45 processors from Intel (including Xeon), you also get new professional GPUs from Nvidia. The ThinkPad P1 is the workstation counterpart and the fourth generation gets a major update, because Lenovo now uses 16-inch displays with the 16:10 aspect ratio. The ThinkPad X1 Extreme is Lenovo’s Multimedia flagship notebook for a couple of years now and is primarily competing with the Dell XPS 15.
