Intel Xeon W-11855M vs AMD Ryzen 7 PRO 2700U vs AMD Ryzen 5 2400G

Intel Xeon W-11855M

The Intel Xeon W-11855M is a high end hexa core SoC for laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates six Willow Cove processor cores (12 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 3.2 GHz. The single and dual core boost speed can reach up to 4.9 GHz (using ITBM 3.0), all cores can reach up to 4.4 GHz. The CPU offers 18 MB level 3 cache and supports DDR4-3200 memory.

The Xeon W-11855M is the fastest 6-core CPU of the Tiger Lake line-up at launch and should easily best the older 6 core CPUs thanks to the high clock speeds and the new architecture. Therefore, the Xeon is well suited for even very demanding tasks and is only bested by the 8-core CPUs like the W-11955M.

The SoC also included the improved Xe graphics card called UHD graphics with all 32 EUs.

Furthermore, Tiger Lake SoCs add PCIe 4 support (20 lanes in the H45 series), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E 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). The default TDP is rated at 45 W at 3.2 GHz base speed, at 35 Watt the base clock speed decreases to 2.6 GHz (cTDP down).

AMD Ryzen 7 PRO 2700U

The AMD Ryzen 7 PRO 2700U is a mobile SoC that was announced in October 2017. Compared to the consumer Ryzen 7 2700U, the PRO versions offer additional security features. It combines four Zen cores (8 threads) clocked at 2.2 - 3.8 GHz with a Radeon RX Vega 10 graphics card with 10 CUs (640 Shaders) clocked at up to 1300 MHz. The TDP can be configured by the laptop manufacturer between 12 to 25 Watt (15 Watt nominal) and therefore the APU is also suited for thin and light laptops. The integrated dual-channel memory controller supports up to DDR4-2400 memory. More information on Raven Ridge can be found in our launch article.

The performance of the Zen CPU cores should be better than a high end Kaby-Lake-Refresh Quad-Core CPU (e.g. the Core i7-8650U) according to AMD. Therefore, the Ryzen 7 PRO 2700U is suited for all applications.

AMD Ryzen 5 2400G

The AMD Ryzen 5 2400G is a desktop APU that was announced in early 2018. It is the fastest Raven Ridge APU at that time and features all four Zen cores (8 threads due to SMT support) clocked at 3.6 - 3.9 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (all of the 704 Shaders on the chip) clocked at up to 1250 MHz. The integrated dual-channel memory controller supports up to DDR-2933. The TDP is specified at 65 Watt and the CPU, GPU and memory are unlocked for overclocking.
