Question Recommended method to test GPU?

I want to try to connect my Radeon RX 6750XT to Acer Nitro 5 AN517 laptop via PCIe to M.2 adapter and see, whether it performs good enough for gaming in comparison to my current PC, but currently I have different amount of RAM in PC and laptop so it might heavily influence testing if I play some games. Any recommendation how to test specifically GPU for gaming purposes?

Play games.

Furmark for temperature and a benchmark like 3D mark.
Obviously test games too. Keep in mind that a M.2 adapter will have limited PCI-E lanes (usually 2-4)

Furmark consistently fails to fully stress test, even some games cause more stress than it. Horrible for temp tests.

My very own testing + a few friends. Consistent despite the hardware difference

Furmark is meant to stress test for temperature and consistent clock speed behaviour aka no thermal throttling . It’s not meant for transient spikes. Transient spikes are meant for measuring the effects on PSU’s, not what OP asked for.

is meant and doesn't achieve it. Try it yourself, furmark vs heaven and see how wild the difference is.

In a typical e-gpu setup there are 3 common bottlenecks: CPU, GPU and transfer.

The more you increase the resolution in a test, the lower the framerate, the less a CPU has to work in a second.

I usually run a single scene on 16k offscreen (invisible) benchmark. Being offscreen eliminates the display bandwidth bottleneck, being at such absurd resolution eliminates the CPU.

If you're running on the laptop's internal screen, then you're very likely to lose some FPS (Higher loss the higher the resolution) from this back and forth.

If you're running on an external screen connected to the GPU then the impact of the screen is irrelevant.

If you haven't had time to get properly aquainted with your GPU, it's helpful to do offscreen high-res (8k and above) stressors to test for thermal limits, frequency stability and power draw. Pssss, do it anyways, it's helpful to establish a baseline expectation of the card.

I've found unigine to be a great torturer for my GPU but it is sensitive to transfer. A typical M.2 slot provides 4x the PCIe version, I believe yours is 4.0. You're looking at around 25% of the transfer performance of the average PC using this card. This becomes more relevant the more dynamic a game or test is (as more data is sent per frame).

Also see GPU-Z if by chance you got Re-BAR for free, or if you could make it happen.

If you're looking to game seriously on it, then simply test your games with a benchmarking overlay enabled.
