Intel’s 8th Gen Coffee Lake-H ‘High-Performance’ Notebook Processors Launched – First To Feature Core i9 and 6 Cores on Mobility Devices

Today is the day when we finally get to see what Intel has been cooking secretly for the notebook market. Over the last couple of years, Intel’s mainstream and mobile lineup was stuck with 4 cores and 8 threads in flagship part. This changed with the 8th generation family which brought a core bump to the desktop lineup last year. Now, Intel is bringing the same core bump over to the high-performance notebook sector which has become a slightly heated space due to the resurgence of AMD and their mainstream Ryzen processors.

Today’s announcement is a full fledged lineup which is part of the Intel Coffee Lake-H family. These products not only include the Core series processors but Intel’s Xeon class workstation chips are also launching today. The notebook Core lineup tackles various market segments such as Enthusiast Gaming, Content Creation, VR/MR, Mega-Tasking, Data Analysis, Business on the Go and work station tasks. Some key features of the Coffee Lake-H lineup include:

  • First Intel Core i9 and 6-Core Processor Laptops
  • Highest Mobile Performance with New Intel Thermal Velocity Boost
  • New Mobile Intel 300 Series Chipset With Enhanced Audio and I/O
  • New Integrated Intel Wireless-AC With Gigabit Throughput
  • New High Speed Integrated USB 3.1 Gen2 (10 Gb/s)
  • First Intel Optane Memory Laptop Solution
  • Optimized For The Latest Discrete Graphics and Thunderbolt 3

Intel’s Thermal Velocity Boost (TVB) Functionality

The Intel Thermal Velocity Boost feature is supported by the Intel Core i9-8950HK and Xeon E-2186M processors. It is designed to increase performance of both, multi-threaded and single-threaded workloads. The maximum core frequency is achieved while the processors is at a temperature of 50C or lower and turbo power budget is available. Frequencies are expected to reduce over time as the processor temperature increases.

Intel Coffee Lake-H Notebook Processor Lineup and Specifications

Coming to the lineup, the 8th generation Coffee Lake-H family has a total of seven processors. Two of these are Xeon models while the rest are Core models. All of the processors are based on the 14nm++ process node and feature support for Intel Optane memory while the new 300-series chipset also adds integrated Giga bit Wi-Fi which is capable of being up to 2 times faster than standard wireless LAN connections.

Intel Core i9-8950HK – The Flagship 6 Core Notebook Chip With Up To 4.8 GHz Clock at 45W

The flagship SKU of Intel’s Coffee Lake-H lineup is the the Core i9-8950HK which is a 6 core part with 12 threads. This chip features 12 MB of L3 cache and is geared to run up to 4.8 GHz clock on a single core while all core boost will be set at 4.3 GHz, base clock will be set at 2.90 GHz. The chip comes with a fully unlocked design and will scale well with notebooks featuring good cooling systems if Thermal Velocity Boost feature is to be taken into account.

Intel Core i7 6 Core / 12 Thread and Core i5 4 Core/ 8 Thread Coffee Lake-H Parts Squeeze More Performance Into Notebooks

The other SKUs include the Core i7-8850H which falls right below the Core i9. This is also a 6 core, 12 thread part but lacks the Core i9 branding. The reason is that it has partial overclocking support and will feature lower clock speeds. The chip has 9 MB of L3 cache compared to full 12 MB on the i9 SKU and will feature clock speeds of 2.60 GHz base, 4.0 GHz boost (all core) and 4.3 GHz (one core boost). The other 6 core, 12 thread part is the Core i7-8750H which comes with the same specs as the Core i7-8850H but has clock speeds of 2.20 GHz base, 3.9 GHz (all core) and 4.2 GHz (one core boost).

There are also two quad core parts with 8 threads. These include the Core i5-8400H and Core i5-8300H. Both feature 8 MB of L3 cache and the former features clock speeds of 2.5 GHz base, 4.1 GHz (All core) and 4.2 GHz (one core boost) while the latter features clock speeds of 2.30 GHz base, 3.9 GHz (All core) and 4.0 GHz (one core boost) frequencies. All chips in the Coffee Lake-H lineup will include the Intel UHD 630 graphics chip which will be clocked at 1100 MHz. All chips will ship with a 45W TDP while the flagship parts will be configurable down to 35W.

When it comes to performance numbers, Intel is saying a 29% overall performance boost for the Core i9 compared to a 7th Gen Core i7 H-series flagship chip. It’s also up to 41% better in gaming performance and game streaming performance is said to be 32% better. Content creation which benefits from increased core count will yield up to 59% better results during 4K video editing. The core bump for notebook platforms has been long awaited and we finally have some capable performance tier mobile solutions in the market.
