AMD Ryzen 7 6800U

The AMD Ryzen 7 6800U is a processor for thin and light laptops based of the Rembrandt generation. The R7 6800U integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.7 (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. Compared to the similar R7 6800H, the 6800U 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.

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 6800U in our database easily shoulders its way towards the best of the best, trading blows with the Core i7-1270P, the Core i7-11850H and the Ryzen 7 PRO 6850H as far as multi-thread benchmark scores are concerned. Throw everything you can at this little guy. He'll take it all and ask for more.

Thanks to its decent cooling solution and a long-term CPU power limit of more than 20 W, the Mercury EM680 is among the fastest systems built around the 6800U that we know of. It can be at least 20% 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 15 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, a proper cooling solution is a must.

The R7 6800U is manufactured on the 6 nm TSMC process for higher-than-average, as of mid 2023, energy efficiency.
