A surprise twist from Intel
Any expectations I had of a slower and less turbulent late summer and fall for the technology and hardware segments is getting shattered today with the beginning stages of Intel’s 8th Generation Core Processors. If you happen to think that this 8th generation is coming hot on the heels of the 7th generation that only just released to the consumer desktop market in January of this year, you’d be on the same page as me. If you are curious how Intel plans to balance Kaby Lake, Coffee Lake, and Cannon Lake, all releasing in similar time frames and still use terms like “generation,” then again, we are on the same page.
Today Intel launches the 15-watt version of its 8th Generation Core Processors, based on a refresh of the Kaby Lake CPU design. This not a new architecture nor is this is not a new process node, though Intel does talk about slight changes in design and manufacturing that make it possible. The U-series processors that make up the majority of the thin and light and 2-in-1 designs for consumers and businesses are getting a significant upgrade in performance with this release. The Core i7 and Core i5 processors being announced will all be quad-core, HyperThreaded designs, moving us away from the world of dual-core processors in the 7th generation. Doubling core and thread count, while remaining inside the 15-watt thermal envelope for designs, is an incredible move and will strengthen Intel’s claim to this very important and very profitable segment.
Let’s look at the specifications table first. After all, we’re all geeks here.
|Core i7-8650U||Core i7-8550U||Core i5-8350U||Core i5-8250U||Core i7-7600U||Core i7-7500U|
|Architecture||Kaby Lake Refresh||Kaby Lake Refresh||Kaby Lake Refresh||Kaby Lake Refresh||Kaby Lake||Kaby Lake|
|Base Clock||1.9 GHz||1.8 GHz||1.7 GHz||1.6 GHz||2.8 GHz||2.7 GHz|
|Max Turbo Clock||4.2 GHz||4.0 GHz||3.8 GHz||3.6 GHz||3.9 GHz||3.5 GHz|
|Cache (L4 Cache)||8MB||8MB||6MB||6MB||4MB||4MB|
|System Bus||DMI3 - 8.0 GT/s||DMI3 - 8.0 GT/s||DMI2 - 6.4 GT/s||DMI2 - 5.0 GT/s||DMI2 - 5.0 GT/s||DMI2 - 5.0 GT/s|
|Graphics||UHD Graphics 620||UHD Graphics 620||UHD Graphics 620||UHD Graphics 620||HD Graphics 620||HD Graphics 620|
|Max Graphics Clock||1.15 GHz||1.15 GHz||1.1 GHz||1.1 GHz||1.15 GHz||1.05 GHz|
The only differences between the Core i7 and Core i5 designs will be in cache size (Core i5 has 6MB, Core i7 has 8MB) and the clock speeds of the processors. All of them feature four true Kaby Lake cores with HyperThreading enabled to support 8 simultaneous threads in a notebook. Dual channel memory capable of speeds of 2400 MHz in DDR4 and 2133 MHz in LPDDR3 remain. The integrated graphics portion offers the same performance as the 7th generation designs, though the branding has moved from Intel HD Graphics to Intel UHD Graphics. Because Ultra.
But take a gander at the clock speeds. The base clock on the four new CPUs range from 1.6 GHz to 1.9 GHz, with 100 MHz steps as you go up the SKU ladder. Those are low frequencies for modern processors, no doubt, but Intel has always been very conservative when it comes to setting specs for base frequency. This is the speed that Intel guarantees the processors will run at when the CPU is fully loaded using a 15-watt TDP cooling design. Keeping in mind that we moved from dual-core to quad-core processors, it makes sense that these base frequencies would drop. Intel doesn’t expect users in thin and light machines to utilize all 8 threads for very long, or very often, and instead focuses on shorter use cases for multi-threaded workloads (photo manipulation) that might run at 3.x GHz. If this period of time is short enough, the cooling solution will be able to “catch up” and keep the core within a reasonable range.

Intel has announced a live event on August 21 to reveal the new 8th-generation Core processor family. The Facebook Live stream will be available on both Intel's Facebook page or simply by visiting the Intel Newsroom, and it begins at 8:00 PDT (11:00 EDT) on 8/21.
What exactly is being discussed? Intel provides these bullet points for the event which is to take place just before the upcoming national solar eclipse:
- Don’t be caught in the dark. Learn how the 8th Gen Intel Core processor family will offer blazing fast performance.
- Hear directly from Gregory Bryant, senior vice president of the Client Computing Group at Intel, and others about the details on the latest processor family and what it can help you do.
- Discover how immersive experiences will bring you from spectator to participant with 8th Gen Intel Core processor capabilities.
- Don’t just take our word for it. See the power of 8th Gen Intel Core technology come to life in the hands of a VR creator and imaging technologist.
- Get a sneak peek at some of the amazing system designs based on 8th Gen Intel Core processors.
- Start planning for what new 8th Gen Intel Core processor-based device to purchase in the holiday season and even before.
- Don’t worry, you won’t miss the solar eclipse. Tune in before it descends upon Oregon and the West Coast and then makes its way across the U.S.
- See how the 8th Gen Intel Core processor is designed for today and what comes next.
We will cover the event which will provide official details on the rumored Coffee Lake CPU lineup. Stay tuned!

During it's keynote at Computex today, Intel announced the high performane Skylake-X and Kaby Lake-X platforms with CPU core counts as high as 18 (!!) but also gave a brief mention of its upcoming Coffee Lake product, the 8th Generation Core product family.
To quote directly from the Intel press information:
"As we move toward the next generation of computing, Intel also shared its commitment to deliver 8th generational Intel® Core™ processor-based devices by the holiday season, boasting more than 30 percent improvement in performance versus the 7th Gen Intel® Core™ processor."
That is quite the claim, but let's dive into the details.
Based on SYSmark* 2014 v1.5 (Windows Desktop Application Performance). Comparing 7th Gen i7-7500U, PL1=15W TDP, 2C4T, Turbo up to 3.5GHz, Memory: 2x4GB DDR4-2133, vs. Estimates for 8th Gen Core i7: PL1=15W TDP, 4C8T, Turbo up to 4 GHz, Memory: 2x4GB DDR4-2400, Storage: Intel® SSD, Windows* 10 RS2. Power policy assumptions: AC mode. Note: Kaby Lake U42 performance estimates are Pre-Silicon and are subject to change. Pre-Si projections have +/- 7% margin of error.
In a more readable format:
|Code name||Coffee Lake||Kaby Lake|
|Process Tech||14nm Double Plus Good||14nm+|
|Base Clock||?||2.7 GHz|
|Turbo Clock||4.0 GHz||3.5 GHz|
|TDP||15 watt||15 watt|
|Memory Clock||2400 MHz||2133 MHz|
The 30% performance claim comes from both a doubling of core and thread count (2- to 4-cores) but also a 500 MHz higher peak Turbo Clock, going from Kaby Lake to Coffee Lake. The testing was done using SYSmark 2014 v1.5, a benchmark that is very burst-centric and is comparable to common productivity tasks. Even with a 15% increase in peak clock speed and a 2x core/thread count, Intel is still able to maintain a 15 watt TDP with this CPU.
While we might at first expect much larger performance gains with those clock and core count differences, keep in mind that SYSmark as a test has never scaled in such a way. We don't yet know what other considerations might be in place for the 8th Generation Core processor platforms, and how they might affect performance for single of multi-threaded applications.
Intel has given us very little information today on the Coffee Lake designs, but it seems we'll know all about this platform before the end of the year.
