The Intel Core i3-7100U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.4 GHz (without Turbo Boost) 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 should be 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. Compare to the old Skylake Core i3-6100U, the i3-7100U offers a 100 MHz improved clock speed.
Architecture
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.
The AMD Athlon 300U is a mobile entry level dual core SoC that was announced in January 2019. It combines two Zen cores (with SMT / Hyperthreading so running 4 threads) clocked at 2.4 - 3.3 GHz with a Radeon RX Vega 3 graphics card with 3 CUs (192 Shaders) clocked at up to 1000 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. It is quite similar to the AMD Ryzen 3 3200U (2.6 - 3.5 GHz).
Compared to the Picasso APUs of the Ryzen 3000 series, the Athlon 300U is still based on the first generation of the 2000 series. Only the PRO variant is based on the new Zen+ microarchitecture that should lead to a 3% IPS (performance per clock) improvement.
The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.
In contrast to the faster quad-core Picasso APUs, the Athlon 300U only supports 3 instead of 4 displays in total.
Performance wise, the Athlon 300 should be slightly slower than the Ryzen 3 2200U (2.5 - 3.4 GHz Dual Core with SMT).
The Intel Core i5-7300HQ is a quad-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. Compared to the faster Core i7 models, the Core i5 does not support Hyper Threading and has lower clocks. The CPU cores run at 2.5 - 3.5 GHz (4 cores up to 3.1, 2 cores up to 3.3 GHz). The processor is also equipped with the HD Graphics 630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm process with FinFET transistors.
Architecture
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
The performance should be quite similar to the old Core i5-6440HQ (2.6 - 3.5 GHz, Skylake) that offers the same per-MHz performance and only 100 MHz higher core speed. The performance is therefore sufficient even for demanding tasks.
Graphics
The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1000 MHz (i7 models up to 1100). The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.
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. Intel still specifies the TDP with 45 Watts, but it can also be reduced to 35 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.
