The GPU performance is clearly limited in battery mode. A ThinkPad P1 with an ISV-certified Nvidia GPU should be chosen for CAD.

The conclusion for the professional benchmark suite SPECviewperf is more mixed: Here, the GeForce-P1 achieves partly good, but also partly poor results. In this case, the GeForce is certainly worth it. Nevertheless, the gap to the ThinkPad X1 Extreme G3 with GeForce GTX 1650 Ti Max-Q is huge (+148%), even compared to the Nvidia T1200 variant of the P1, the GeForce RTX 3070 is more than twice as fast in the 3DMark benchmarks (+118%). Thus, it is no wonder that the RTX 3070 is about 10% faster on average across all laptops than here in the Lenovo ThinkPad P1 2021. In the case of Lenovo's ThinkPad P1 G4, however, the 5120 shader units are far from their maximum performance because Lenovo sets the GPU to a TGP of 80 watts - in the past, this variant would have been called "Max-Q". The Nvidia GeForce RTX 3070 is one of the most powerful mobile GPUs of Nvidia's current "Ampere" generation. We could not determine a CPU performance limitation in battery mode. In the Cinebench R23 multi-core test, the Vapor-Chamber P1 is 27% faster than the cheaper model, it is roughly on par with the HP ZBook Studio 15 G8. Therefore, the processor can permanently consume around 60 watts under pure CPU load here, whereas the CPU of the less equipped ThinkPad P1 Gen 4 with Nvidia T1200 was limited to around 40 watts. The reason is not the processor, but the cooling system: The model with GeForce RTX 3070 tested here contains vapor-chamber cooling. With our CPU list the Intel processor can be compared with other CPUs.Īctually, the i7-11850H is practically as fast as the i7-11800H, the difference is mainly due to the vPro support of the 11850H - but in the ThinkPad P1 G4, the difference between the two is big. Nominally, the TDP of this CPU is 45 watts however, this consumption is not sufficient to reach the maximum clock rates of 4.8 GHz on all cores.

The Intel Core i7-11850H is a current processor from the "Tiger-Lake" series with eight cores and 16 threads. Since we recently tested the ThinkPad P1 2021 in a lower-end configuration, we refer to the review of the ThinkPad P1 Gen 4 with Nvidia T1200 for details about the configuration, input devices and design. Lenovo has significantly upgraded the ThinkPad P1 and equipped our test model with an Nvidia GeForce RTX 3070 and 4K UHD+ resolution that corresponds to one of the strongest configuration variants. However, customers do not necessarily have to sacrifice performance anymore - at least on paper. The new Lenovo ThinkPad P1 G4 still has its mobility advantage compared to the ThinkPad P15 G2, the current full-fat ThinkPad workstation. The classic workstation model Lenovo ThinkPad P52 on the other hand, offered more performance with less mobility. When Lenovo launched the ThinkPad P1 in 2018, the distribution of roles in the workstation lineup was clear: The new premium model was supposed to pick up buyers who needed a particularly thin and light mobile workstation and could sacrifice some performance for it.
