GPU performance after sleep

A few days ago I received my new Macbook Pro - Mid 2020 with Intel Core i7-1068NG7 and 32GB ram. After restart all works well and I'm getting a score of 10,000+ for Metal on Geekbench 5. After a sleep, this score drops to 2,700-3000 and doesn't recover until I restart.

Looking at Geekbench results, I'm not the only one with this problem.

Using "Intel Power Gadget" I reviewed the GPU Frequency and indeed, after a restart the frequency going all the way up to 1.1 GHz. After the laptop come back from sleeping, the GPU frequency never exceeds 300 MHz.

Any suggestion how to resolve?

MacBook Pro 13″, macOS 10.15

I have same performance problems on my macbook pro after wake-up from sleep. I did som benchmarks and here are the results:

Low performance after wake-up: https://browser.geekbench.com/v5/compute/1187426

Good performance after restart: https://browser.geekbench.com/v5/compute/1187448

This problem does not occurs on every wake-up, only sometimes. I googled many threads on different forums where users are complaining about performance problems with wake-ups but without any solution.

Same problem here. Apple, this is unacceptable, really. It happens even on the newest models!

Macbook Pro 2017, Catalina (latest release available on July 15).

Reboot allows to workaround the issue but it need to be fixed right away.

Same benchmark after a reset. You'll notice that GPU frequency is hitting 1.1 GHz and the over all CPU package is hitting the 27W limit, as it should.

Here's an example during a benchmark, you'll notice the both GFX REQ and GFX AVG are at 0.30 GHz. Overall CPU package power is not anywhere near the limit.
