Tonight at the consumer electronics trade show IFA in Berlin, Intel announced their latest processors aimed at thin-and-light notebooks and 2-in-1 devices. Continuing the ever elongated 8th generation processor family from Intel, these new mobile CPUs are comprised of both 5W (Amber Lake-Y) and 15W (Whiskey Lake-U) parts.
|Core i7-8565U||Core i7-8550U||Core i5-8265U||Core i5-8250U||Core i3-8145U|
|Architecture||Whiskey Lake||Kaby Lake Refresh||Whiskey Lake||Kaby Lake Refresh||Whiskey Lake|
|Base Clock||1.8 GHz||1.8 GHz||1.6 GHz||1.6 GHz||2.1 GHz|
|Max Turbo Clock||4.6 GHz||4.0 GHz||3.9 GHz||3.6 GHz||3.9 GHz|
Just as we saw with the Kaby Lake Refresh CPUs last year, these 15W parts maintain the same quad-core, eight-thread configurations.
On the highest end part, the i7-8565U, we see an increase of 600MHz on the max turbo clock, while the base clock remains the same. The i5-8265U sees a smaller uptick of 300MHz boost while also keeping the same base clock of 1.6GHz as the previous generation.
|Core i7-8500Y||Core i7-7Y75||Core i5-8200Y||Core i5-7Y75||Core m3-8100Y||Core m3-7Y32|
|Architecture||Amber Lake||Kaby Lake||Amber Lake||Kaby Lake||Amber Lake||Kaby Lake|
|Base Clock||1.5 GHz||1.3 GHz||1.4 GHz||1.2 GHz||2.1 GHz||1.1 GHz|
|Max Turbo Clock||4.2 GHz||3.6 GHz||3.9 GHz||3.3 GHz||3.9 GHz||3.0GHz|
As we can see, the Amber Lake CPUs provide a significant frequency advantage over the previous Kaby Lake-Y processors, especially with the turbo frequencies ranging from 600-900MHz improvements.
These higher frequencies give these low power processors a substantial performance uptick from the previous generation, as long as the thermal solutions in the end product notebooks are up to the task of actually achieving these high turbo boost frequencies.
Across the board, Intel is marketing these CPU platforms as having increased connectivity options, with built-in 802.11AC 160MHz dual-band Wi-Fi support (which Intel is referring to as Gigabit WiFi). Additionally, both the Amber Lake and Whiskey Lake families have options to be paired with Intel LTE modems for cellular connectivity.
Also on the connectivity side, we see support for native USB 3.1 Gen 2 (10 Gbps) ports through the chipset on Whiskey Lake-U.
Intel is also touting battery life improvements with "16 hours on a single charge with power-optimized systems targeted to achieve about 19 hours" on the Whiskey Lake-U platform. However, as always, take these specifications with a grain of salt until we see real products with these processors integrated into them and benchmarked.

Intel's rollout of their "8th Generation" processors has been glacial compared to other generations, and overall a bit confusing when it comes to trying to decode what processor belongs to what architecture.
Past the 8th generation Kaby Lake-R 15W quad-core mobile processors in August of last year, the Coffee Lake-S desktop CPU launch in October, and the recent Kaby Lake-G launch combining Intel processors with AMD graphics, there has still been one big missing market—high performance mobile processors.
Today, Intel is finally rounding out it's 8th Generation Mobile processor line-up with the addition of Coffee Lake-H processors.
The biggest change with Intel's new mobile lineup is the delightful addition of more cores. All i7 and Xeon-based SKUs will now have 6 cores with Hyper-threading enabled for a total of 12 threads. In addition, the entire i5 lineup is gaining Hyper-threading support, bringing them to 4 cores and 8 threads.
Coffee Lake-H also marks the introduction of Intel's first "i9" branded processor, the i9-8950HK. Taking the top spot of the mobile lineup previously held by the i7-7920HQ, the i9-8950HK is fully unlocked, with a turbo frequency of up to 4.8GHz.
In addition, all of these new 8th generation mobile processors will bring support for Optane Memory caching to mobile for the first time.
Intel is achieving the 4.8GHz single core turbo boost on the i9-8950HK through what they are calling "Intel Velocity Boost." While there aren't a lot of details about exactly how this technology will work yet, Intel has told us that essentially it's a way of providing extra frequency if there is thermal headroom on a given notebook design.
Below the 50 degrees C target temperature, we were told to expect about a 200MHz single-core boost and a 100MHz multi-core boost. With factory overclocking, Intel says they expect to see OEMs hit 5GHz and beyond, thanks in part to Velocity Boost.
In addition to new processors, Intel is also unveiling their new 300-series mobile chipsets today. The major additions include the adoption of USB 3.1 Gen 2 ports directly from the chipset, as well as the integration of an 802.11ac radio.
The all-new wireless radio is said to be capable of Gigabit speeds using 2x2 MIMO at 160MHz, which is part of the Wave 2 specification. While routers that support the 160MHz band are few and far between today, hopefully, Intel's adoption of this technology into its chipset will help spur faster adoption.
In addition to the H-series processors, Intel also unveiled several new U-series parts today with Iris Plus graphics.
While the 28W notebook processors combining Intel U-series parts with Iris graphics containing 128MB of eDRAM have been available for generations, the only major customer for these parts historically is Apple. I fully expect these processors to make it into a revised 13" MacBook Pro later this year.
These new U-series parts will also be able to take advantage of the new 300-series chipsets with the integrated 802.11ac and USB 3.1 Gen 2 connectivity. It will be interesting to see if Intel finally integrating Wi-Fi capability directly into the chipset will cause Apple to ditch Broadcom on their MacBook lineup.
Stay tuned for more announcements from Intel today, as well of announcements from notebook vendors utilizing these new processors!
