A better monitoring program would be AMD μProf, it shows you the actual power consumption of the APU and PPT slow and fast limits, STAMP limits.etc. It turned out that the "high performance" phase was just a turbo window, the APU uses more than 15 watts (~30) at first, that's why the performance is great, but then it goes back down to its rated TDP (15w), ~6 of which is what I can see reported in AIDA64 and HWiNFO64 (CPU cores) and the rest goes to the iGPU. What settings are you using in Ryzen Controller? I just bought this laptop and im getting the same issue It's ridiculous really, paying for hardware and then not be able to use it at full potential. I did manage to get better performance by forcing it to run at higher TDP using, but that's not something I'm comfortable running all the time since kids are using laptop primarily. I have latest BIOS installed and downloaded latest chipset drivers directly from AMD. Bought it for my niece as Xmas present, to use primarily for school/homework, but also some light gaming since I saw on YouTube reviews Ryzen 3500U running Fortnite comfortably over 60 fps, but mine barely does over 30 on lowest settings at 720p. It weighs 4.1lb.I have the same issue with exact same model. The laptop measures 14.3″ in width x 10″ in depth x 0.8″ in height. It has a TN 1080p display, 802.11ac WiFi, BT 4.2, a camera, a 35Wh battery, 65W power adapter, and Windows 10 64-bit Home.
It has 256GB M.2 NVME SSD on the PCIe bus, but only at PCIe 3.0 x2 speeds, not x4. That’s really the one sticking point that will slow down the system, I wish the RAM was faster, but that seems to be the rated speed for the 3500U. It looks like you’ll be stuck at DDR4 2400 since the soldered RAM is 2400 if you wish to upgrade.
It has 8GB of DDR4-2400 with 4GB soldered and a DIMM with another 4GB. There is even a PDF with more information about the laptop.įrom the specifications, you can see this is a 15.6” laptop with an AMD Ryzen 5 3500U on the AMD SoC Platform. If you search for the specific model number 81UT003WUS you will find all the specifications listed for this laptop. You can actually find this laptop listed, however, with all of the different model types of the 81UT laptop. It doesn’t get much newer than that! This laptop was announced in July of 2019. The manufacture date of my laptop is, that’s right, October 10 th of 2019 this laptop was manufactured. It lists the older model with AMD’s A9, but that should be replaced with the new ones eventually. Now, if you go to Lenovo’s website, it doesn’t actually quite list this new laptop just yet. The laptop is a Lenovo IdeaPad S145-15API Model 81UT003WUS. Let’s first go over the laptop itself and the specifications just so you know the whole picture.
