AMD A10-9620P vs Intel Core i3-7100U vs Intel Core i7-7700

AMD A10-9620P

The AMD A10-9620P is a mid-range APU of the Bristol Ridge series (7th generation of APUs) with 4 CPU-cores (two Excavator modules) clocked at 2.5 - 3.4 GHz. In our tests the A10-9620P even hit 3.6 GHz.

It was announced in 2017 and is based on the same silicon as Carrizo but with more and refined features. It is a ULV-chip with a TDP of 15 Watt and integrates a Radeon R5 graphics card (384 shader cores / 6 compute cores) and a dual-channel DDR4-18600 memory controller. As Carrizo its a full featured SoC that offers all I/O ports on the chip.

The A10-9620P is a bit faster than the old 15-Watt top model of Carrizo, the FX-8800P. See our Bristol Ridge article for more information on the architecture and improvements compared to Carrizo.

Intel Core i3-7100U

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.

Intel Core i7-7700

The Intel Core i7-7700 is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the 65 Watt consumer Kaby-Lake-H series at the time of the announcement. The faster CPUs, like the Core i7-7700K, are specified with 91 Watt. Besides four cores including Hyper-Threading (8 threads) support running at 3.6 - 4.2 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.
