The 13" Lenovo Yoga 720 is one of the first Thunderbolt 3 laptops to sport an Intel 8th generation quad-core ULV processor. The unit I got has an i5-8250U CPU. Intel claims these quad-core Kaby Lake-R models are 40% faster than the dual-core Kaby Lake predecessors. What about eGPU performance improvement?

I'm sorry to say I don't have a definitive answer yet. The Lenovo Yoga 720 lineup is crippled with x2 PCIe lanes over Thunderbolt 3 connection issue. The 13" model is also effected by OPI GT2 low-power mode. These issues are bigger concerns to eGPU performance than dual vs quad core CPU.

I recently reviewed the OMEN Accelerator and besides this Yoga 720, I also tested the Razer Blade Stealth. The Razer is one of the few ULV ultrabooks to have full x4 PCIe lanes and runs in OPI GT4 high-performance mode. Take a look at the benchmark results. Far left is Razer Blade Stealth external display mode, middle is Yoga 720 external display mode, right is Yoga 720 internal display mode.

Here are additional screen captures of AIDA64 to confirm half bandwidth of the Lenovo Yoga 720 when compared to the Razer Blade Stealth.

Could please also indicate OS versions, AMD and Intel drivers used?

Really unfortunate the Lenovo is crippled. I am really curious about the 8th gen performance with full lanes

I'm on the look out for an ultrabook with the 8th gen, full four lanes, and GT4.

Spectre 13 X360 looks like a good candidate.

Can you please also verify/note the FW version of the Omen Accelerator?

Definitely. I only know how to check in macOS. It shows 25.25 on the unit I have.

@itsage: You say that the 720 has 2 lanes available but doesn't your hwinfo screenshot show 4 lanes? I'm a bit confused.

Hi, will the late-2017 yoga 720 be charged through the GPU dock?

Planned solution is Aorus Box + yoga 720.

Thanks.
