MagyarAMD Ryzen 5 PRO 6650H vs Intel Celeron 5205U
AMD Ryzen 5 PRO 6650H
► remove from comparison
The AMD Ryzen 5 PRO 6650H is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6650H integrates six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm TSMC process. The Ryzen 5 PRO 6650H is the professional version of the consumer R5 6600H with additional management features and the Microsoft Pluton Security processor.
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, DDR5-4800 or LPDDR5-6400, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.
Performance
While we have not tested a single system powered by the Ryzen 5 PRO 6650H as of August 2023, it's safe to expect the chip to be about as fast as the 6600HS.
Your mileage may vary depending on how high the CPU power limits are and how comfortable the cooling solution of your system is.
In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6650H only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock rate.
The TDP of the APU is specified at 45 Watts (default). The power efficiency should be very good, thanks to the improved 6 nm process and additional power saving features in the 6000 series.
Intel Celeron 5205U
► remove from comparison
The Intel Celeron 5205U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Celeron 4205U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at only 1.9 GHz (no Turbo) and don't support SMT / HyperThreading (so only 2 threads). More information on Comet Lake and all the models and articles on it can be found here.
The integrated graphics adapter is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 4205U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster and costlier Core i3/i5/i7 processors).
Performance
While we have not tested a single system powered by the 5205U as of August 2023, it's safe to expect the chip to be about half as fast as the Core i3-10110U (Comet Lake, 2 cores, 4 threads, up to 4.1 GHz). Which is nothing to write home about, really, as of mid 2022.
Power consumption
This Celeron has a default TDP, also known as the long-term power limit, of 15 W. Intel officialy allows laptop manufacturers to reduce that value somewhat, 12.5 W being the lower limit, resulting in lower clock speeds and lower performance. Unlike most Comet Lake family processors, Celeron 5205U is fairly likely to actually stick to that limitation as its cores are not Boost-enabled.
Last but not the least, this CPU is manufactured on an old, as of late 2022, 14 nm Intel process making for subpar energy efficiency.
