After being extremely happy with the performance and stability of my Lenovo Thinkpad E14 Gen 2 eGPU System, I decided to upgrade to a slightly higher performance laptop: the Yoga Slim 7i Pro 14. This laptop has some interesting features for a 14" Ultrabook, and fixes the shortfalls the E14 had:

Advantages over the ThinkPad E14:
- Higher performance H35 CPU (i7-11370H)
- Dual Channel RAM @ 4266Mhz
- GDDR6 MX450 (Vs GDDR5)
- Large Battery (61Wh)
- Dual Thunderbolt 4 Ports
- High Resolution 16:10 Screen (Up to a 2880x1800, 90Hz, OLED)
- Quieter and lower peak temperatures than the E14

 

One of the most interesting features this laptop has is a BIOS Level Discrete GPU Switch. This disables the NVIDIA MX450 at BIOS Level and is no longer visible to the OS at all. This is extremely useful for an eGPU System where driver conflicts or performance / stability issues occur when a discrete GPU is present. This is an issue I had with my E14, having to disable and then re-enable the MX450 upon a system start. This is no longer the case:

Another feature that I appreciate in a non-gaming laptop is BIOS level Performance Profiles. Under Intelligent Cooling, the laptop runs very quietly and performs almost identically to my i7-1165G7 E14 System in Cinebench. With the Extreme Performance Mode enabled there is considerably more fan noise, but the CPU now outperforms the i7-1165G7 in both Single and Multicore Cinebench R23.

The Thunderbolt Control Centre shows four Thunderbolt 4 Ports and Two Controllers:

So far the Yoga Slim 7i Pro has done everything the E14 did plus some. Although it is only early days, it is probably the best eGPU Ultrabook I have used to date. I will be doing a more in depth review and eGPU system build soon.

@boltoway, I never like utility software to switch modes in OS level so those options in BIOS are great! Thank you for sharing these findings. I only wish there was an ultrabook with H45-CPU and iGPU only.

@itsage, There seems to be one as of now. I do not think it qualifies as an UltraBook as it is made of Plastic and is quite bulky. The laptop details are:

Latitude 5521 Laptop:

Video Card:Intel® UHD Graphics - Intel 11th Gen Core i5-11400H (non-vPro)

 

2019 13" MacBook Air [8th,2C,Y] + GTX 1070 @ 32Gbps-TB3 (AORUS Gaming Box) + Win10 2004 [build link]

Here is an UltraBook with the Intel H45 CPU and an iGPU.

Dell Precision 15 5560 Mobile Workstation.

It looks exactly like the Dell XPS 15 but comes without the dGPU.
