Intel Processor N100 vs Intel Core i5-7200U vs Intel Core i3-7100H

Intel Processor N100

The Intel Processor N100 is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with 1 to 3.4 GHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache.

Performance

The average N100 in our database delivers unimpressive multi-thread benchmark scores that are most similar to those of the Core i3-1115G4. The chip is fast enough for many day-to-day tasks, but not much more than that; the other thing to keep in mind is that of the two N100-toting systems tested by us as of October 2023, both have rather high CPU power limits. The chip will be noticeably slower if limited to just six or seven Watts.

Features

The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).

The integrated graphics adapter is based on the Xe-architecture and offers only 24 of the 32 EUs (Execution Units) operating at only 450 - 750 MHz. Due to the single channel memory, low clock speeds, and low shader count, the gaming performance of the iGPU is very limited.

Power consumption

The N100 has a base power consumption of only 6 W and is therefore suited for fanless cooling. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).

Intel Core i5-7200U

The Intel Core i5-7200U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.5 - 3.1 GHz and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz is very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1000 MHz). It is manufactured in an improved 14nm FinFET process at Intel. Compared to the old Skylake based Core i5-6200U, the i5-7200U offers a 300 MHz higher clock speed.

Intel Core i3-7100H

The Intel Core i3-7100H is a dual-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It is probably based on the quad-core die from the other H-series processor with two deactivated cores considering the TDP and the integrated HD Graphics 630. The two CPU cores run at 3GHZ without a Turbo, and the processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel HD Graphics 630 GPU, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.

Architektur

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

Compared to the similarly branded, but much more efficient Core i3-7100U (2.4 GHz, 15-Watt TDP), the i3-7100H has much higher clocks and the performance is almost on par with theCore i5-7200U (2.5-3.1 GHz).

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 950 MHz in this case. The performance depends a lot on the memory configuration. Compared to HD 620 GPUs, the higher TDP could result in better sustained performance.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. The TDP is pretty high for a dual-core processor at 35 Watts, so the CPU is not suited fpr thin and light notebooks (where the i3-7100U comes into play).
