The Intel Core i7-11800H is a high end octa core SoC for gaming laptops and mobile workstations. It is based on the Tiger Lake H45 generation and will be 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 2.4 GHz. The single core boost speed can reach up to 4.6 GHz, all cores can reach up to 4.2 GHz. The CPU offers 24 MB level 3 cache and supports DDR4-3200 memory. Compared to the slower clocked i7-11800H, the 11850H offers professional management features like Intel vPro, SIPP or TXT.
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 2.4 GHz base speed, at 35 Watt the base clock speed decreases to 2 GHz (cTDP down).
The Intel Pentium Gold 4425Y is a low power entry level processor for small laptops or tablets and based on the Kaby Lake architecture. It was announced in Q1 2019 and offers two processor cores clocked at 1.7 GHz (no Turbo Boost). Thanks to Hyper Threading, the processor can execute up to four threads simultaneously. The chips also includes the Intel HD Graphics 615 GPU, a dual-channel memory controller (DDR3L/LPDDR3) as well as VP9 and H.265 video de- and encoder. It is still produced in a 14 nm process with FinFET transistors. Compared to the much faster Core m3-7Y30, the Pentium 4425 offers no Turbo Boost, different CPU and GPU clock speeds, a smaller L3 cache and a higher TDP of 6 Watt. Compared to the predecessor Pentium Gold 4415Y from 2017, the Pentium Gold 4425Y is clocked 100 MHz higher (the CPU cores).
Architecture
Intel basically used the familiar micro architecture from the Skylake generation, so the per-MHz performance is identical. Only the Speed-Shift technology for faster dynamic adjustments of the voltages and clocks was improved, and the matured 14 nm process now also enables much higher frequencies and better efficiency than before.
Performance
Due to the missing Turbo Boost, the Pentium 4425Y offers a significantly worse single thread performance than the more expensive Core m3-7Y30. This should be noticeable in daily tasks. Compared to older CPUs, the Pentium Gold should match a Core i3-4100U (100 MHz higher clock speed but older architecture).
Graphics
The integrated Intel HD Graphics 615 GPU has 24 Execution Units (EUs) like the old HD Graphics 515 and runs with clocks between 300 and 850 MHz in combination with this processor. The performance heavily depends on the TDP limit as well as the memory configuration; with fast LPDDR3-1866 RAM in dual-channel mode, the GPU should sometimes be able to compete with the HD Graphics 520, but can also be much slower in other scenarios. Modern games from 2016 will, if at all, only run smoothly in the lowest settings.
Contrary to Skylake, Kaby Lake now also supports hardware decoding for H.265/HEVC Main10 with a 10-bit color depth as well as Google's VP9 codec.
Power Consumption
The chip is manufactured in an improved 14 nm process with FinFET transistors, so the power efficiency was once again improved significantly. The TDP is rated at 6 Watt and can be reduced to 4,5 Watt (cTDP down).
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).
