I don't understand why people continue to compare laptops with 15W cpus like the Huawei Matebook X Pro or Microsoft Surface Book 2 to laptops with 38/45W CPUs. On CPU intensive workloads an i7-8550U is going to under perform an i7-7920HQ pretty soundly, around 40-50%, particularly for sustained workloads where the i7-8550U is going to start throttling hard to stay within it's TDP boundaries. If you're considering a laptop with an i7-8550U in it, it's doubtful you're in the target market for a Macbook Pro, at least certainly not the 15" model, the 13" is at least a little closer in performance depending on workload. The i7-8550U seems like a great option in the 15W category and smashes previous 15W parts. But, it's not a competitor in the 'Pro' market if anything you do leverages the CPU heavily. It's also just a matter of time before intel releases quad core 38W parts which will pull laptops like the 13" MBP far ahead in performance again.
