New Lenovo Legions laptops are coming tipped to be the 5 series but interestingly there are references to the Legion 5 and 5i on the Lenovo PSREF site as well. According to Notebookcheck, there are three models listed on PSREF including the Lenovo Legion 5 15IMH05, 15IMH05H, and 15ARH05.
On the other hand, the Lenovo BIOS simulator also shows the presence of a 15ARH05H model, but that listed in PSREF. Although both the Legion 5 15IMH05 and 15IMH05H models looks identical expect for some minor differences.
Both of these models are powered by the latest Intel Comet Lake-H gaming CPUs including the Core i5-10300H, Core i7-10750H, and the Core i7-10875H. The difference lies in terms of the GPUs theses two laptops providing you with.
The Legion 5 15IMH05 is equipped the NVIDIA GeForce GTX 1650 and GTX 1650 Ti options, whereas, the 15IMH05H offers you to choose between the GTX 1660 Ti and the RTX 2060. The RTX 2060 seems to be the highest GPU offering by Lenovo.
In terms of display, the 15IMH05 offers some choices including entry-level FHD 250-nit 120 Hz IPS panel with a 45% NTSC, a 144 Hz 300 nits display and a 240 Hz 500 nits Dolby Vision display. On the other hand, the 15IMH05H does not offer the entry-level display but the other choices are constant. According to the spec sheet, the 15IMH05H shreds off the 720p webcam.
On the AMD front, the Lenovo Legion 5 15ARH05 features the AMD Ryzen 5 4600H and Ryzen 7 4800H CPU options whereas there sre GPU options between the GTX 1650 and the GTX 1650 Ti. Rest most the specs are similar to the Comet Lake-H-powered Legion 5 SKUs.
Only in the display, the AMD ones feature a FHD 144 Hz 300 nits Dolby Vision with no 240 Hz option at all. On the other hand, the PSREF does not have any sign of a15ARH05H SKU but we an it is seen in the Lenovo BIOS simulator tool as well as in the Japanese download page for the Dolby Vision Provisioning Utility.
This could mean that Lenovo might be hiding the offering that might feature an RTX 2060 GPU with AMD Renoir processor options.
Also it’s being noted in MobileMark 2018 battery life, the Legion 5 15IMH05 and 15IMH05H powered by Comet Lake-H processors last up to 7.7 hrs for a 80 Wh battery whereas, the 15IMH05H also powered by Comet Lake-H processors last up to 7.7 hrs for the 80 Wh battery and 6.8 hrs for the 60 Wh variant.
On the AMD front, the Legion 5 15ARH05 powered by Ryzen 4000-H processors have a longer battery life, the MobileMark result says the laptop can last up to 13.5 hrs for the 80 Wh cell and 12.5 hrs for the 60 Wh option. This is incredible and expected from a 7 nm CPU actually.
