Anyway, unless there is a very good cooling system on the laptop, a faster apu might throttle, resulting in slower sustained speed. For that price, I doubt it will be an excellent cooling system.
Cooling is one factor, but most importantly, these are low power APUs. With the very limited power shared between the CPU and GPU, we should not expect them to sustain performance like their desktop counterparts.

Very disappointed. Seems like Lenovo gave a very underwhelming cooling system or some weird issues. CPU start to throttle at 70 degree.

Geekbench scores were terrible. Will try again tmr after optimising.

Wow.. the scores for multicore is pathetic

The initial battery life looks terrible as well. I don't know what's wrong, but I will try to troubleshoot tmr. CPU utilisation is low...

Might be a firmware issue.....

The CPU wasn't even taxed at 100% majority of the time.... Very very weird.

At 8% average cpu utilization, 2% average gpu utilization, wifi on, 50% brightness, It lasted 4 hours 37 mins. Quite terrible stats...

I will try again tonight after optimizing.

Try clean reinstall then AMD Drivers from AMD Website. Also need Lenovo Power Management Driver
The processor must boost until 100% when running CPUZ Benchmark if required under power options set minimum CPU utilization 55%.
On my Ryzen 1700 on Windows Server processor must be set to 55% otherwise clock will be stuck
Must use HWMonitor to check the processor state.

Cinebench 15 shows good results and outperform the i7 8550 in multicore. I will say that have to fine-tune the processor for geekbench as mentioned by artic. Try tonight

If after update driver to latest still isn't performing.
Maybe try do fresh install of OS cuz
Stock OS usually comes with bloatware.
Whether or not the image was done on Intel NB u never know.
Yes I saw some AMD NB with such image.
Inside there few software like Intel UHD graphics.

Minor review.
1. I set the processor to 100% and it managed to get a much better score on geekbench, but still not pushing the processor 100%. https://browser.geekbench.com/v4/cpu/9192730

2. Cinebench 15 shows that it outperforms i7 8550u by 5% on multicore and lose by 10% on single core. I will say it performed really well. No thermal throttling that I can see.

3. 3dMark skydiver shows a score of 800, which is very close to the dedicated mx150 GPU in most ultrabooks. (MX 150 in Ultrabooks is usually slightly throttled because of heat)

4. SSD performance is really good. The 512 GB samsung has a sequential read of 2.7GB per second and write of 2GB per second. 4k read writes are about 10 - 20% better than the E480 review on notebookcheck. However, the ssd controller temp went up to 98 degree. (SSD brand is a lottery, so don't expect samsung in every laptop. Your mileage will vary)

5. Screen brightness is quite low and I will expect to use 50% brightness in a well lit room, in comparison to the usual 25% for my other laptops. The matt display is great although I can see very faint bleeding at the bottom. Acceptable for this price.

6. I managed to squeeze 7 hours out of this laptop by setting max cpu to 70% so it will not turbo boost in battery. However, the lowest possible clock I can get it to go consistently is at 1.6ghz. My settings are: Wifi on, 25% brightness, 2.5% average cpu utilization, 10% average highest cpu core utilization. If you are consistently visiting javascript heavy (or ad heavy) webpages like hardwarezone, then expect your "average highest cpu core utilization" to spike and as a result, much heavier power usage. I will say on average, a uptime of 4 to 6 hour is very achievable. However, it is still poorer than a intel chip. I will expect intel to have an extra 20 - 30% extra runtime.

7. It can be charged or run from a external USB PD powerbank. A 100 wh powerbank will easily give an extra 150% - 180% more battery life to you on the road.

8. It is a thinkpad keyboard.

9. In conclusion, I think this laptop is a fantastic buy if you want to game occasionally or require 16 GB ram for multi tasking / development work, despite the "subpar" wifi. In everyday usage, wifi is not expected to be a bottleneck, so it is not a factor in my review. I hope this can be of help to those considering this laptop.

Is it metal or still plastic like E475?
Higher quality plastic but still plastic

Ordered mine on 20 July, expected shipment date delayed till 10 August. Emailed them and then mentioned they are having parts shortage, hmmm.

It's an E485, 2x4GB, 256GB and FHD.

To be fair this is suppose to be Ryzen 5 SKU should use Ryzen 7 vs i7 to be fair
