 If these CPUs disappoint you, well you better hope for an ARM transition because Intel isn’t releasing anything better for a while.

I'm not sure why people pretend that AMD doesn't exist and ARM is the only solution.

AMD's 4800U is a 15W 8 core / 16 thread chip with excellent performance that easily beats out Intel's 25W 6 core / 12 thread 10710U.

What laptops use a 25-28W (or lower if the performance is better) AMD mobile CPU? What is the battery life? I can’t find anything talking about battery life tests and the Ryzen 4000 series. I’m not saying they don’t exist but are they being used by companies like HP, Lenovo and Dell? Customers who need a large and reliable quantity of CPUs to create a flagship. A flagship AMD CPU in the 1.5-1.7 cm (0.60” - 0.67”)  thickness range and weighing about 1.4 kg (3 pounds) would be ideal as a comparison to the 13” MacBook Pro.

AMD might get there but they are just starting out being competitive in the mobile space for the first time. That makes it hard for a company needing millions of CPUs per quarter to design for AMD.

Edit: And I should mention that the Intel Core i7-10710U is a 14 nm part and only supports Intel UHD graphics which is not as strong as the Iris Plus. Not really a one to one comparison.

So I'll add one more thing to that.

Noise level:

MBP - 29 dB(A) idle / 33 dB(A) load mid / 41.8 dB(A) load max
Razer - 30 dB(A) idle / 33.9 dB(A) load mid / 38.1 dB(A) load max

So clearly it's possible to create a thin and light laptop with a dGPU. A lower power dGPU like the MX250 or MX350 could also be used.

Customers of some gaming laptops should bear in mind that performance while plugged in and unplugged are different. It's not uncommon for a high performance dGPU in laptop to be restricted to 1/3rd its performance while unplugged. There's always a cost.

Still no dGPU?

Razer fit a GTX 1650 Ti Max-Q 4 GB into their 3 lbs laptop with a 25W Ice Lake i7 CPU. They also have the option for a 120 Hz or 4K display.

As well, AMD's 4000U series (up to 8 cores and 16 threads at 15 W) is hitting the market with far better performance than this in both CPU and iGPU performance.

Apple fixing their keyboard is nice, but this is a very weak update.

The problem with a dGPU in a 13" laptop, where there's not much room for a big battery, is battery drain. The Razer you cite is optimized for gaming, which isn't Apple's thing. I can't find any claims for how long its battery lasts under load, but my guess is that its usage case calls for AC power to be connected for any kind of extended use with the dGPU active. I do see that the Razer calls for a 100W AC power supply, which seems...troubling.

Instead, the entry-level iPhone produces depth maps entirely through machine learning. That also means that it can produce Portrait Mode photos from both its front- and rear-facing cameras. That's something undoubtedly made possible by the top-of-the-line A13 Bionic chipset underneath its hood.
