Intel Core i5-3570K vs Intel Core i5-11260H vs Intel Core i9-11900KB

Intel Core i5-3570K

The Intel Core i5-3570K is a fast quad-core desktop processor based on the Ivy Bridge architecture. Each core offers a base speed of 3.4 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.6 GHz (for 4 active cores), 3.7 GHz (for 2 active cores) and 3.8 GHz (for 1 active core). Furthermore, the "K" series processors offers an unlocked multiplier for easy overclocking.

Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and  DDR3(L)-1600 support.

The performance of the Core i5-3570K is slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. Compared to AMD's fastest desktop CPU (FX-8350), the Core i5-3570K offers significantly higher performance per thread, but features less cores (4 instead of 8). Overall, the Core i5 is still a bit faster in most applications.

The integrated Intel HD Graphics 4000 GPU offers 16 Execution Units (EUs) clocked at 650 MHz up to 1150 MHz with Turbo Boost. For recent games, the performance is only sufficient for low resolutions and details.

The total power consumption of the CPU, graphics and memory controller is specified by Intel at 77 watts (TDP).

Intel Core i5-11260H

The Intel Core i5-11260H is a mid range hexa 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 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 2.6 GHz. The single and dual core boost speed can reach up to 4.4 GHz, all cores can reach up to 4 GHz. The CPU offers 12 MB level 3 cache and supports DDR4-3200 memory.

Thanks to the new Tiger Lake architecture, the i5-11260H should be able to reach the level of the high clocked Intel Core i7-10850H (Comet Lake-H, 6 cores, 2.7 - 5.1 GHz, 16 MB L3) in single and multi threaded performance. Compared, to current AMD offerings, the 11260H should perform similar to a Ryzen 5 5600H (6 cores, 2.4 - 3.3. GHz, 16 MB L3 cache) or the 5600HS when the TDP is set to 35W.

The SoC also features a much improved UHD Graphics (16 EUs) iGPU based on the Xe architecture.

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 in 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 2.6 GHz base speed, at 35 Watt the base clock speed decreases to 2.1 GHz (cTDP down).

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).
