AMD Ryzen 5 PRO 2500U vs Intel Core i5-11500B vs Intel Core i9-11900KB

AMD Ryzen 5 PRO 2500U

The AMD Ryzen 5 PRO 2500U is a mobile APU for thin and light business laptops that was announced in January 2017. Compared to the similar consumer Ryzen 5 2500U, the PRO 2500U offers additional security features and longer part availability / warranty.

It includes four Zen cores clocked at 2 to 3.6 GHz and offers 4 MB L3-Cache. The integrated graphics card is called Radeon RX Vega 8 and offers 8 CUs (512 Shaders) clocked at up to 1100 MHz. The TDP is configurable between 12 and 25 Watt (15 Watt nominal). More information on Raven Ridge can be found in our launch article.

Intel Core i5-11500B

The Intel Core i5-11500B is a hexa-core processor for desktops and mini PCs. It is based on the Tiger Lake architecture (H45) and was presented in Q2 2021. The chip offers a TDP of 65 watts (configurable). The six processor cores can clock from 3.3 to 4.6 GHz (single-core turbo). The processor offers 12 MB level 3 cache and supports DDR4 RAM with up to 3,200 MT/s. The integrated graphics are based on the Xe architecture and are named UHD Graphics (32 EUs). In the 11500B it clocks from 350 to 1,450 MHz. The chip is manufactured using the 10 nm SuperFin process.

Performance

The performance of the Intel Core i5-11500B depends primarily on the performance of the installed cooling unit. The TDP of the SoC can also be lowered. In principle, however, the Intel Core i5-11500B should offer slightly more performance than an Intel Core i5-11400H (6 cores 2.7 - 4.5 GHz).

Features

As with the smaller Tiger Lake chips, Wi-Fi (Wi-Fi 6E) and Thunderbolt 4 / USB 4 are (partially) integrated into the chip for faster, cheaper and space-saving implementations in desktops and mini-PCs. The i5-11500B also offers 20 PCIe 4.0 lanes.

Intel Core i9-11900KB

The Intel Core i9-11900KB is an Octa-Core-CPU that was used in the Intel Beast Canyon NUC. It is based on the Tiger-Lake-H45 series and was announced in the second quarter of 2021. The processor cores can clock from 3.3 to 5.3 GHz, all cores at once can reach up to 4.9 GHz. The CPU features 24 MB level 3 cache and DDR4-3200 memory. The integrated UHD graphics card is based on the Xe-architecture with 32 cores and clocks up to 1.45 GHz.

As with the slower Tiger Lake-H CPUs, the 11900KB has a partly integrated WiFi 6E and Thunderbolt 4 in the chip. Furthermore, the 11900KB supports 20 PCIe 4.0 lanes.

The TDP is rated at 65 Watt with 3.3. GHz base clock and can be configured to 55 Watt (cTDP-down).
