AMD Ryzen 7 5800U vs Intel Core i5-11320H

AMD Ryzen 7 5800U

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.

Intel Core i5-11320H

The Intel Core i5-11320H is a mid range SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 refresh generation and will be announced in Q3 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and can vary from 2.5 (28 W TDP) to 3.2 GHz (35 W). The boost of a single and two cores under load can reach up to 4.5 GHz. All four cores can reach up to 4.3 GHz. The L3 cache is reduced to 8 MB compared to the 12 MB of the higher end i7 models.

Thanks to the improved clock speeds, the performance gap to the faster i7-11370H should be quite small. The i7 still offers higher single and dual core Turbo speeds and more L3 cache.

The SoC also included the improved Xe graphics card with 96 CUs clocked at up to 1350 MHz.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6 in the chip.

The chip is produced on the improved 10nm process (called 10nm SuperFin) at Intel, which should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
