AMD Ryzen 5 PRO 6650U vs Apple M2 Pro 10-Core
AMD Ryzen 5 PRO 6650U
► remove from comparison
The AMD Ryzen 5 PRO 6650U is a processor for thin and light laptops based of the Rembrandt generation. The Ryzen has six out of a possible eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.9 (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 6650U is the professional version of the consumer R5 6600U with additional management features and the Microsoft Pluton Security processor. Compared to the similar R5 6650H, the 6850U offers a lower base clock speed and a lower TDP.
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.
Performance
The average 6650U in our database is very close to the Core i7-1260P and the Core i7-10870H, as far as multi-thread benchmark scores are concerned. This is a really good result, as of late 2022.
Thanks to its decent cooling solution and a long-term CPU power limit of 32 W, the ThinkPad T16 G1 is among the fastest laptops built around the 6650U that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6650U only offers the small Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock rate.
The TDP of the APU is specified at 15 - 28 Watts (default). The power efficiency should be very good, thanks to the improved 6nm process and additional power saving features in the 6000 series.
Apple M2 Pro 10-Core
► remove from comparison
The Apple M2 Pro 10-Core is a System on a Chip (SoC) from Apple that is found in the early 2023 MacBook Pro 14 and Mac Mini entry level models. It offers 10 of the 12 cores available in the chip divided in six performance cores (P-cores) and four power-efficiency cores (E-cores). The E-cores clock with up to 3.4 GHz, the P-Cores up to 3.7 GHz (mostly 3.3 GHz in multi-threaded workloads and 3.4 GHz in single threaded).
The big cores (codename Avalanche) offer 192 KB instruction cache, 128 KB data cache, and 36 MB shared L2 cache (up from 24 MB in the M1 Pro). The four efficiency cores (codename Blizzard) are a lot smaller and offer only 128 KB instruction cache, 64 KB data cache, and 4 MB shared cache. CPU and GPU can both use the 24 MB SLC (System Level Cache).
The unified memory (16 or 32 GB LPDDR5-6400) next to the chip is connected by a 256 Bit memory controller (200 GB/s bandwidth) and can be used by the GPU and CPU.
The performance of the M2 Pro 10-Core should be similar to the old M1 Pro with all 10 cores. The multi-threaded performance should be slower, as the M2 10-core has two p-cores less (and 2 e-cores more) but the single-threaded performance should be better due to the faster clock speed and architectural improvements. The old M1 Pro 8-core should be noticeably slower.
The integrated graphics card in the M1 Pro 10-core offers all 16 of the 19 cores.
Furthermore, the SoC integrates a fast 16 core neural engine (faster than M1 Pro), a secure enclave (e.g., for encryption), a unified memory architecture, Thunderbolt 4 controller, an ISP, and media de- and encoders (including ProRes).
The M2 Pro is manufactured in 5 nm at TSMC (second generation) and integrates 40 billion transistors.
