The AMD Ryzen 7 5800U is a processor for thin and light laptops based on the Cezanne generation. The R7 5800U integrates all eight cores based on the Zen 3 microarchitecture and is the fastest U-series processor at launch. They are clocked at 1.9 (guaranteed base clock) to 4.4 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 7 nm TSMC process.
The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.
Performance
The average 5800U in our database matches the Core i5-11260H and, perhaps a little disappointingly, the Ryzen 7 4800U in multi-core performance.
Thanks to its decent cooling solution and a long-term CPU power limit of 22 W, the ProBook x360 435 G8 is among the fastest laptops powered by the 5800U that we know of. It can be more than 10% 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, a value that laptop makers are allowed to change to anything between 10 W and 25 W with clock speeds and performance changing accordingly as a result. Choosing the lowest value would allow one to build a passively cooled system around the Ryzen, however, most laptop manufacturers will do the opposite to extract as much performance out of the chip as possible.
The Ryzen 7 5800U is built with TSMC's 7 nm process for average, as of mid 2023, energy efficiency.
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.
