AMD Ryzen 5 6600H vs AMD Ryzen 9 5900X vs AMD Ryzen 7 6800H
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.
AMD Ryzen 9 5900X
► remove from comparison
The AMD Ryzen 9 5900X is a high-end 12-core, hyperthreaded (SMT) Vermeer series desktop processor that can process 24 threads simultaneously. Introduced on October 8, 2020, the Ryzen 9 5900X is the fastest 12-core processor and is specified at 105 watts TDP. The top model, the AMD Ryzen 9 5950X, offers even more power and at the same time offers another 4 cores and 8 threads.
The Ryzen 9 5900X clocks with 3.7 GHz base clock and reaches up to 4.8 GHz on one core in turbo mode. However, when all 12 cores are loaded, up to 4.5 GHz is still possible.
The performance of the AMD Ryzen 9 5900X is consistently excellent in all applications and significantly better than the AMD Ryzen 9 3900X. AMD has been able to significantly improve its single thread performance in particular and even beats the Intel Core i9-10900K in this discipline. The multi-thread performance could also be improved. In an in-house duel, the AMD Ryzen 9 5900X can even take on an AMD Threadripper 2950X.
The internal structure of the processor has not changed fundamentally at first glance. The CCX structure has changed a bit compared to Zen2, because now a CCX consists of up to 8 CPU cores. So each individual core can access the complete L3 cache (32 MByte). Furthermore the CCX modules are connected to each other via the same I/O die, which we already know from Zen2. According to AMD, the Infinity-Fabric should now reach clock rates of up to 2 GHz, which in turn allows a RAM clock of 4.000 MHz without performance loss.
For the manufacturing processes, AMD also relies on TSCM for the Vermeer processors for the 7nm production of the CPU cores, although the I/O die is still supplied in 12nm by Globalfoundries.
In games, the AMD Ryzen 9 5900X is convincing thanks to the significantly improved IPC. With the AMD Ryzen 9 5900X, streaming can be done simultaneously with gaming. But if you only want to play games, you are well advised to take a closer look at the AMD Ryzen 7 5800X or the AMD Ryzen 5 5600X.
AMD Ryzen 7 6800H
► remove from comparisonThe AMD Ryzen 7 6800H is a processor for big (gaming) laptops based on the Rembrandt generation. The R7 6800H integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.2 (guaranteed base clock) to 4.7 GHz (Turbo) and support SMT / Hyperthreading (16 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.
A big novelty is the integrated GPU Radeon 680M that is now based on the RDNA2 architecture and offers 12 CUs at up to 2.2 GHz. It should be the fastest iGPU of all at the time of announcement.
Performance
The average 6800H in our database is in the same league as the Core i5-12500H and the Core i7-12650H, as far as multi-thread benchmark scores are concerned. The Ryzen 9 5900HX is found close nearby as well.
Thanks to its decent cooling solution and a long-term CPU power limit of 90 W, the Legion 5 Pro 16ARH7H is among the fastest systems built around the 6800H that we know of. It can be about 60% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Ryzen 7 series chip has a default TDP, also known as the long-term power limit, of 45 W. An active cooling solution is a must for a CPU like this.
The R7 6800H is built with TSMC's 6 nm manufacturing process for above average, as of mid 2023, energy efficiency.
