The answer is nuanced. It can run workloads somewhat faster and cooler than Pi 4 without active cooling. But it also can't reach close to its peak performance without active cooling.

Your answer is more direct and uses fewer words. Can you help them fix their product page?
Probably not ;)
The actual info I'd rely upon at this point:
https://www.phoronix.com/benchmark/result/raspberry-pi-5-coo...
pi5 with active cooler is about 1.2-1.5x faster than pi5 without cooler for most workloads that care than without.
Pi5 with active cooler is about 2-2.5x faster than Pi4. So Pi5 without cooler is probably about 1.5x faster than pi4, depending upon workload. (And more than this for quick bursts where thermal mass wins).
Should we get Intel and AMD to clarify their product pages at the same time?
Haha - and while we’re at it, might as well start putting labels on Apple’s performance graph slides :-)

Does that mean for the same load the power requirements of the pi5 are lower than the pi4?
Yes, that's what they directly claim. Phoronix's measurements seem to (indirectly) bear this out. https://news.ycombinator.com/item?id=37686214
"The combination of a newer core, a higher clock speed, and a smaller process geometry yields a much faster Raspberry Pi, and one that consumes much less power for a given workload."
