Lenovo ThinkBook 13s G3 AMD laptop in review: Subnotebook with fast Ryzen CPU
AMD Ryzen 7 5800U | AMD Radeon RX Vega 8 (Ryzen 4000/5000) | 13.30" | 1.3 kg
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.
