MagyarAMD Ryzen 5 6600H vs Intel Core i5-9400H vs AMD Ryzen 9 PRO 6950H
AMD Ryzen 5 6600H
► remove from comparison
The AMD Ryzen 5 6600H is a processor for big (gaming) laptops based of the Rembrandt generation. The R5 6600H 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 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.
In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6600H only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock speed.
Performance
The average 6600H in our database is in the same league as the R7 5825U, the R7 6800U and also the Core i5-1340P, as far as multi-thread benchmark scores are concerned. This is a very decent result, as of late 2022.
Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.
Power consumption
This Ryzen 5 series APU has a default TDP, also known as the long-term power limit, of 45 W. A high-performance cooling solution is a must for a system built around such a chip.
The R5 6600H is built with TSMC's 6 nm process for great, as of early 2023, energy efficiency.
Intel Core i5-9400H
► remove from comparison
The Intel Core i5-9400H is a high-end processor for laptops with four cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.5 and 4.3 GHz (4.1 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i5-8400H from 2018, the 9300H is only clocked slightly higher (+100 MHz CPU Turbo, +50 MHz GPU).
The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).
Performance
The Intel Core i5-9400H should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-9750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-9400H should be sufficient for even demanding applications and games.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.
Power Consumption
Intel specifies the TDP with 45 watts and therefore the i5 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
Beware, the CPU was not yet released at the time of writing and the information is based on leaks and early price list information (e.g. by Intel or on Baidu).
AMD Ryzen 9 PRO 6950H
► remove from comparisonThe AMD Ryzen 9 PRO 6950H is a processor for big (workstation) laptops based on the Rembrandt generation. The R9 6900HX integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.9 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 6 nm TSMC process. The 6950H is the professional version of the consumer R9 6900HX without overclocking features but with additional management features and the Microsoft Pluton Security processor.
The new Zen 3+ architecture 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.
A big novelty is the integrated GPU Radeon 680M, that is now based on the RDNA2 architecture and offers 12 CUs at up to 2.4 GHz. It should be the fastest iGPU of all at the time of announcement.
Performance
While we have not tested a single system built around the 6950H as of August 2023, we have tested one system featuring the 6950HS, its slightly more power-efficient brother. Based on that, expect the 6950H to be slightly faster than the Ryzen 7 5800H, Ryzen 9 4900H, Ryzen 5 PRO 7640HS and also the Core i7-11800H. In other words, this is a higher-end chip that will handle almost any task with ease, as of late 2022.
Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.
Power consumption
This Ryzen has a default TDP of 45 W (also known as the PL1). A high-performance cooling solution is a must for a CPU like this one here.
Ryzen 9 PRO 6950H is built with TSMC's 6 nm process leading to great, as of late 2022, energy efficiency.
