Lenovo did not change the case compared to the previous model. The lid is made of aluminum, while all the other parts are made of plastic. Both the lid as well as the smooth top of the base unit are very susceptible to fingerprints, so you will have to clean it regularly. The overall stability is very good and there is only minor creaking noises when we try to twist the base unit.
Our test unit shows good build quality, but the lid is not perfectly aligned with the base unit, which is noticeable at slightly protruding edges when the device is closed. The whole bottom part can be removed, but you have to be careful not to damage the plastic hooks. 8 GB RAM are soldered onto the mainboard, but you can use one SODIMM slot to expand the memory and there is one empty M.2-2242. You can replace the Wi-Fi module, but unlike the ThinkPad L15 G2, there is no WWAN module.
Our test unit is equipped with the AMD Ryzen 7 5700U with 8 cores (16 threads), which is manufactured in a 7 nm process, but it is still based on the Zen 2 architecture. The recently reviewed ThinkPad L15 G2 is already equipped with Zen 3 chips and is even available with Ryzen Pro CPUs that offer enhanced security features.
The CPU maintains a power consumption of 30W (8x 3.3 GHz) for a while and only starts dropping to 25W after around 15-20 minutes. The performance is very good and the new processor is about 30-40% faster than the old Ryzen 7 4700U in multi-core tests. Intel’s Tiger Lake-U chips are clearly beaten and only have a small advantage in single-core tests. The new Zen 3 CPUs (see ThinkPad L15 G2), however, have already closed the gap. The CPU performance is not reduced on battery power.
Thanks to the powerful processor and the PCIe-SSD, the E15 G3 is a very fast and responsive companion, which is also supported by the synthetic benchmarks. There won’t be any bottlenecks in the next couple of years.
The ThinkPad E15 G2 has two M.2-SSD slots (PCIe 3.0 x4) and our test unit is equipped with a M.2-2280 drive, which means you can use the free M.2-2242 slot for storage expansion. The SSD from SK Hynix (PC711) offers a generous storage capacity of 1 TB and you can use around 912 GB after the initial set-up. Transfer rates are very good and the SSD is one of the fastest PCIe 3.0 drives. More SSD benchmarks are available here.
The new ThinkPad E15 G3 is still a very quiet laptop, and you can only hear a quiet murmur from the fan under load. It is often completely silent in everyday situations and even short peak load is handled without the fan. We noticed a quiet electronic noise during some benchmarks, which seemed to originate from the SSD, but we did not hear it on any other occasion. Our test unit did not suffer from coil whine.

(-) The average temperature for the upper side under maximal load is 39.1 °C / 102 F, compared to the average of 29.5 °C / 85 F for the devices in the class Office.
(-) The bottom heats up to a maximum of 60.9 °C / 142 F, compared to the average of 36.5 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25.7 °C / 78 F, compared to the device average of 29.5 °C / 85 F.
(±) Playing The Witcher 3, the average temperature for the upper side is 37.4 °C / 99 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (32.3 °C / 90.1 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 27.9 °C / 82.2 F (-4.4 °C / -7.9 F).
The two speakers (2x 2W) are located at the bottom (front edge) and can be really loud. They do a good job for an office laptop and they are completely sufficient in an office environment (conferences, videos).
Our consumption measurements do not reveal any surprises. Contrary to Intel based laptops, the consumption is stable for a while during the stress test at around 53-54W and then drops towards 47-48W. The included 65W power adapter (USB-C) is completely sufficient.
Thanks to the increased battery capacity (from 45 to 57 Wh), the battery runtime is longer now. Our Wi-Fi test at 150 nits runs for almost 10 hours and still more than 7 hours with the maximum brightness. These are very good results and there is no disadvantage for AMD systems anymore. A full charge takes two hours when the device is turned on (59% after 38 minutes).
