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.
Whiskey Lake-U
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 |
Process Tech | 14nm+ | 14nm+ | 14nm+ | 14nm+ | 14nm+ |
Cores/Threads | 4/8 | 4/8 | 4/8 | 4/8 | 2/4 |
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 |
Memory Support | DDR4/LPDDR3 | DDR4/LPDDR3 | DDR4/LPDDR3 | DDR4/LPDDR3 | DDR4/LPDDR3 |
Memory Speeds | 2400/2133 | 2400/2133 | 2400/2133 | 2400/2133 | 2400/2133 |
Cache | 8MB | 8MB | 6MB | 6MB | 4MB |
TDP | 15W | 15W | 15W | 15W | 15W |
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.
Amber Lake-Y
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 |
Process Tech | 14nm+ | 14nm+ | 14nm+ | 14nm+ | 14nm+ | 14nm+ |
Cores/Threads | 2/4 | 2/4 | 2/4 | 2/4 | 2/4 | 2/4 |
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 |
Memory Support | LPDDR3 | LPDDR3 | LPDDR3 | LPDDR3 | LPDDR3 | LPDDR3 |
Memory Speeds | 1866 | 1866 | 1866 | 1866 | 1866 | 1866 |
Cache | 4MB | 4MB | 4MB | 4MB | 4MB | 4MB |
TDP | 5W | 4.5W | 5W | 4.5W | 5W | 4.5W |
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.
It is hard to get excited
It is hard to get excited until testing can confirm how long those turbo speeds can be maintained, a 25% boost speed uplift is negated if the CPU hits it’s tdp limit 25% faster. Amber-Lake is more impressive, but they’ve also lifted the tdp limit by ~11% which accounts for the majority of the speed bump. Seems like 14nm is just about maxed out, 10nm can’t come soon enough.

According to Intel’s ark, they’re 1.1GHz base, 3.4GHz boost.
Any word from Intel on how
Any word from Intel on how these processors are affected by the recent round of CPU speculative execution hacks (beyond just Spector and Meltdown since we know there are more fixes coming).
