AMD Ryzen 7 5800U vs AMD Ryzen 5 5600U
AMD Ryzen 7 5800U
► remove from comparison
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.
AMD Ryzen 5 5600U
► remove from comparison
The AMD Ryzen 5 5600U, not to be confused with Intel's Core i7-5600U, is a fairly fast Cezanne family processor designed for use in thinner, lighter laptops. The R5 5600U integrates six of the eight cores based on the Zen 3 microarchitecture and is the third fastest U-series processor at launch. The cores are clocked at 2.3 (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT for a total of 12 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 six CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with 7 CUs at up to 1800 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
This Ryzen 5 series chip is a solid mid-range CPU, as of early 2022. Its multi-thread benchmark scores nearly match those of the Intel Core i5-11400H (a much more power-hungry hexa-core chip designed for use in gaming laptops). While not nearly as fast as 12th generation Alder Lake-P processors, the 5600U should be good enough for the vast majority of users.
Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the IdeaPad 5 Pro 14ACN6 is among the fastest laptops powered by the 5600U that we know of. It can be more than 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Ryzen 5 has a default TDP 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. By going for the lowest value possible, it is possible to build a passively cooled system around this chip. Most laptop makers, however, will do the opposite to maximize performance.
