In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600U only offers the small Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock rate.
The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.
Your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.
This Ryzen 5 series chip has a default TDP, also known as the long-term power limit, of 15 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, that's too much to allow for passively cooled designs.
The R5 6600U is manufactured on TSMC's 6 nm manufacturing process for good, as of mid 2023, energy efficiency.
