Has anyone did any bandwidth test with a 802.11AX enabled AP?

I have already seen an AP with 802.11 AX (ASUS) but without a client connected to it. I understand that the Samsung S10 is coming with an SOC which supports 802.11 ax. I really keen to see the benchmark test with an 802.11 ax device. Just wanted to know how much bandwidth it can really achieve compared to the spec.
