Lenovo's mobile workstation T15g appears a bit outdated

Despite its designation, the ThinkPad T15g is a full-fledged mobile workstation and shares the chassis construction with the ThinkPad P15. The design was refreshed, but the device still appears pretty outdated due to massive bezels. There is also an issue with the keyboard and coil whine is a problem as well.

If you see the designation ThinkPad T15g, you might think Lenovo offers a gaming ThinkPad. You also get a fast GeForce RTX Super graphics card, but this is basically a ThinkPad P15, because there are no differences except for the dedicated GPU. If you do not need the ISV certifications of the Quadro GPUs and just want a mobile workstation with plenty of performance for 3D and VR applications, the T15g could be worth a closer look.

Compared to the workstation predecessor ThinkPad P53, we get a new chassis, but the display bezels are still very wide, so the whole laptop looks pretty outdated. The stability is good in general, only the lower left corner of the keyboard is a bit clattery. We also noticed this problem on the ThinkPad P15, so this seems to be a general issue which should be addressed by Lenovo. Lenovo also removed one M.2-2280 slot, so there are only two left. The maintenance options are still great and there is a maintenance hatch for simple access. 

Lenovo also managed to improve the CPU performance, but you are still limited by Intel's old Comet Lake processor. We will have to wait for new Rocket Lake chips to get more performance, since AMD's processors are still very rare among mobile workstations (which is the case for other manufacturers like Dell or HP as well). The graphics performance of the GeForce RTX 2070 Super Max-Q is also stable, but Lenovo implements the least powerful version of the GPU with a TGP of 80W. We can also hear electronic noise when we stress the GPU, which is annoying.

You can choose between 1080p and 4K screens. Our test device was equipped with the matte FHD screen and a brightness of 500 nits. The subjective picture quality is good, but you should calibrate the panel to get the most accurate colors. The advantage of the 108ß panel is the low power consumption, and you can expect between 7-12 hours (depending on the brightness) in practical scenarios.

The T15g might be worth a look depending on your planned usage scenario, and the rivals from Dell and HP just offer better overall packages. Please see our comprehensive review of the ThinkPad T15g for more information:
