Intel Core i9-11900H vs AMD Ryzen Embedded R1606G vs Intel Xeon W-11955M

Intel Core i9-11900H

The Intel Core i9-11900H is a high end octa core SoC for gaming laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.5 GHz. The single core boost speed can reach up to 4.9 GHz, all cores can reach up to 4.5 GHz. The CPU offers 24 MB level 3 cache and supports DDR4-3200 memory. 

Thanks to the new Tiger Lake architecture, the i9-11900H should be similar or faster than the old Intel Core i9-10885H (Comet Lake-H, 2.4 - 5.3 GHz, 16 MB L3) in single and multi threaded performance and similar to the Ryzen 9 5800H (Zen 3, 3.2 - 4.4 GHz, 16 MB L3). Therefore, the i9 should be one of the fastest laptop CPUs in 2021 and well suited for even very demanding tasks.

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 2.5 GHz base speed, at 35 Watt the base clock speed decreases to 2.1 GHz (cTDP down).

AMD Ryzen Embedded R1606G

The AMD Ryzen Embedded R1606G is a dual-core SoC designed for embedded systems that was announced in March 2019. It is similar to the Ryzen 3 3200U (or the 2200U with slightly increased clock speed) and based on the first generation of the Zen architecture. The Ryzen features two Zen cores with support for the thread-doubling SMT tech, clocked at 2.6 GHz - 3.5 GHz. The built-in Radeon RX Vega 3 iGPU has 3 CUs (192 unified shaders) clocked at up to 1,200 MHz. The default TDP is 15 W which makes the Ryzen a good fit for thin mid-range laptops.

In comparison to the faster Ryzen 3000 CPUs, the 3200U and therefore the R1606G is not using the newer Zen+ microarchitecture and is still manufactured in 14nm. Compared to the old Ryzen 3 2200U, the 3200U and R1606G therefore only offers a 100 MHz higher clock speed.

The R1606G is compatible with single-channel or dual-channel DDR4-2400 RAM. Please go to our Raven Ridge launch article for details on the architecture and more.

Intel Xeon W-11955M

The Intel Xeon W-11955M is a high end octa core SoC for laptops and mobile workstations. It is based on the Tiger Lake H45 generation and was announced in mid 2021. It integrates eight Willow Cove processor cores (16 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and at 45 Watt is at 2.6 GHz. The single core boost speed can reach up to 5 GHz (ITBM 3.0, also two cores), all cores can reach up to 4.5 GHz. The CPU offers 24 MB level 3 cache and supports DDR4-3200 memory. Similar to the Core i9-11950H, the Xeon W-11955M supports SIPP, vPro and TXT. In addition to this, the Xeon line supports ECC memory.

Performance

The average W-11955M in our database is in the same league as the Ryzen 7 4800H, Core i7-11850H, Core i7-1360P, as far as multi-thread benchmark scores are concerned. This is a fairly fast chip, as of early 2023.

Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.

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.

Power consumption

This Xeon series chip has a default TDP, also known as the long-term power limit, of 35 W to 45 W, the expectation being that laptop makers will go for a higher value to get better performance.

The W-11955M is built with Intel's third-gen 10 nm process marketed as SuperFin for average, as of early 2023, energy efficiency.
