More than that, compare it to modern cloud CPUs. Epyc 9845 gets 153000 but that's with 160 cores / 320 threads. Per core it's under 1000 and 4 cores would be 3825 when the 11-year-old i7 is 8000.

Because those big systems are optimized for power efficiency. That Epyc is ~2.4W/core compared to ~16W/core for the old i7. It has a lower base clock and is Zen5c. If we cut the 8-core Ryzen 9850X3D's score in half, 4 Ryzen cores from the same generation but with a higher base clock and six times the L3 cache per core would be 20942. But it's also back up to 15W/core. The Epyc still has better performance per watt.

The newer cores are significantly more efficient. That doesn't mean they're unconditionally faster independent of all other variables.
