In our previous comparison, the 8th gen Intel Core i7-8750H outperforms its rival – the Intel Core i7-8705G when it comes to the results from our benchmark tests. And so, today we have chosen yet another 8th gen representative – Intel Core i7-8550U, as a new opponent for the latter.
Specs overview
For starters, Intel Core i7-8705G is based on the Kaby Lake G architecture (8th gen) with a total of 4 cores and 8 threads. Built upon a 14 nm process, it runs at 3.10 GHz base frequency and a maximum speed of 4.10 GHz. Other significant specs include 8MB last level cache, a dual-channel memory controller supporting DDR3L-1600 or DDR4-2400 and a TDP of 65 W. The integrated GPU here is AMD Radeon RX Vega M GL (Vega 870, 4GB HBM2) clocked at 931- 1011 MHz.
Moving on to Intel Core i7-8550U, it is part of the 8th Generation Kaby Lake Refresh CPUs. Manufactured through a 14nm process, the chip adopts the 4/8 core/thread count and is clocked at 1.80 GHz, while its Turbo Boost frequency is 4.00 GHz. The specs sheet is complemented by 8MB last level cache, as well as a dual-channel memory controller that supports DDR4-2400 and LPDDR3-2133, as well as a relatively low TDP of 15W. The chip also incorporates the integrated graphics Intel UHD Graphics 620 clocked at 300-1050 MHz.
