Intel Core i7-8850H vs Intel Core i7-8750H vs Intel Core i7-8559U

Intel Core i7-8850H

► remove Intel 8850H

The Intel Core i7-8850H is a high-end processor for laptops with six cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.6 and 4.3 GHz (4.1 with 4 cores, 4 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process.

The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).

Performance

Due to the two additional cores, performance has increased by almost 50% compared to a similar clocked Kaby Lake processor like the Core i7-7920HQ (3.1 - 4.1 GHz). Single-core performance has not improved since its Kaby Lake predecessor. As a high-end model, the i7-8850H is suitable for the most demanding applications and games.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz (rumored). The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 45 watts and therefore the i7 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.

The Intel Core i7-8750H is a high-end processor for laptops with six cores based on the Coffee Lake architecture and will be announced early 2018. The processor clocks at between 2.2 and 4.1 GHz (4 GHz with 4 cores, 3.9 GHz with 6 cores) and can execute up to twelve threads simultaneously thanks to Hyper-Threading.

Intel Core i7-8559U

► remove

The Intel Core i7-8559U is a quad-core SoC for notebooks based on the Coffee Lake architecture and was announced in April 2018. Compared to its predecessor Core i7-7567U, the CPU is now a quad-core with Hyperthreading support for the execution of up to 8 threads simultaneously. The base frequency is 2.7 GHz, but the Turbo goes all the way up to 4.5 GHz. It is also equipped with an Intel Iris Plus Graphics 655 GPU with 128 MB eDRAM, 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.

Compared to faster Core i5 models with eDRAM and 28 Watts, the i5-8559U features 8 MB smart cache and the fastest clock of the Iris Plus GPU.

Architecture

Intel basically uses the same micro architecture compared to Kaby Lake, 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

Clocked at up to 4.5 GHz, the Core i7-8559U is currently the fastest quad core ULV from Intel. Whether these speeds can be maintained in practice depends on the cooling capabilities of the laptop, but the performance should be above the Core i7-8650U due to the increased TDPConsidering the clocks of the Core i7-8559U, its performance should be between the 15W models Core i5-8350U and Core i7-8550U. The i5-8259U should still be faster than the i7-8550U in practice thanks to the increased TDP, especially during sustained workloads.

Graphics

The integrated Intel Iris Plus 655 Graphics is the GT3e model of the Coffee Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-1200 MHz  and the performance is comparable to a GeForce 930M or 940MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Plus 650, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors 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 specifies the TDP with 28 Watts, which can be reduced to 23 Watts (cTDP Down) depending on the usage scenario. The TDP is pretty high compared to the common 15-Watt TDP for quad-core processors, but allows a better utilization of CPU and GPU Turbo.
