I did not see/hear Apple’s exact claim, though I am seeing the words “match” or “matches" in regard to M1 Max vs. RTX 3080.
In the testing/demonstration showcased in the following article:
As reviewers rushed to the Apple stores to purchase their new expensive toy, which is the MBP (MacBook Pro) M1 Max, benchmarks data flew in, comparing the new beast to an older (Intel-based) MacBook Pro, or to its main rival, the RTX Studio. But, what can we learn from those reviewers...

The RTX 3080 (mobile variant) does outpace the M1 Max by ~30%. However, the RTX 3080 of the competing laptop, an
MSI GE66 Raider 11UH, is designed/manufactured/configured for up to 130W of graphics subsystem power consumption. This is in comparison to the
M1 Max package (CPU, GPU, SSD controller, etc) power peaking at 92W. While not the full story, specs and tests of the latest CPU and GPUs show that power consumption is a generally acceptable comparison, a necessity to push the limits of performance. Last but not least, is the
Apple Silicon native/optimized version of Premiere Pro out of beta status yet? Nonetheless, you are looking at about twice the power consumption (and heat) for only about a third more performance. To me, that seems like a great achievement by Apple.
