AMD Ryzen 9 PRO 6950H vs AMD Ryzen Z1 Extreme vs AMD Ryzen 7 6800H

AMD Ryzen 9 PRO 6950H

The 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.

AMD Ryzen Z1 Extreme

The AMD Ryzen Z1 Extreme is a fast high-end laptop processor of the Phoenix series and fastest model of the U-series. It offers 8 cores (octa core) based on the Zen 4 architecture that supports SMT (hyperthreading , 16 threads). The cores clock from 3.3 (base) up to 5.1 GHz (single core boost). The processor includes 8 MB L2 cache and 16 MB L3 cache.

The performance of the R7 7840U is, depending on the workload, only slightly below the Ryzen 7 7840HS (higher base clock speed and TDP). Compared to the previous generation Ryzen 7 PRO 6850U, the 7840U is clearly faster thanks to the Zen 4 architecture and higher clock speeds. Compared to the similar Ryzen 7 7840U, the Z1 Extreme offers no AI engine.

The chip integrates a modern and fasts RDNA 3 graphics card (iGPU) called Radeon 780M with 12 CUs and up to 2.7 GHz clock speed. Furthermore, the Phoenix series include a video engine with AV1 de- and encoding, a new Xilinx FPGA based XDNA AI accelerator (Ryzen AI) that should be faster than the AI engine in the Apple M2 SOC and a dual-channel DDR5-5600 / LPDDR5x-7500 memory controller (with ECC support). The connectivity features includes 2 possible USB 4 (40 Gbps) ports and 20 PCIe 4.0 lanes for a GPU and SSDs.

The Phoenix series uses a single monolithic design (unlike the chiplet design of the 7045HX series) and is manufactured in the modern 4nm process at TSMC. The TDP can be configured between 15 and 30 Watt.

AMD Ryzen 7 6800H

The 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.
