Ever since Intel introduced the first-generation Core i7, it's followed a predictable series numbering. Offset-generation Core processors were codenamed Nehalem, second-generation CPUs were Sandy Bridge, followed by Ivy Bridge (third), Haswell, (4th) and so on. In each case, new chips — whether they were die shrinks or new architectures — were assigned a new product number. Today, with its 8th-generation fries, Intel is explicitly changing that policy. Unlike previous production generations, the eighth-generation launching today family unit will span multiple flake families built on 14nm+ (Kaby Lake), 14nm++ (Coffee Lake), and 10nm (Cannon Lake).

The iv U-serial chips Intel is launching today are fundamentally based on Kaby Lake with the same architecture, the same GPU, and almost the same capabilities. The i small update to the GPU side of the equation is back up for HDMI 2.0 and HDCP ii.2, without any need for 3rd-party solutions. So what, exactly, is new about these chips? 2 things: Larger cadre counts, and slightly higher clock speeds at maximum Turbo.

8th-Gen

Click to overstate

The table above shows how the new Core i7 chips compare against their seventh-generation predecessors at the 15W TDP. Intel is trading a significant amount of base clock speed for cadre counts, but the maximum turbo speed on these fries is still higher, in some cases, than the parts they replace. The new i5 CPUs aren't shown here, only they compare identically to the Core i7 mobile parts, with higher turbo clocks, quad core configurations with Hyper-Threading, which is historically unusual in the i5 quad-core lineup. Intel doesn't put much accent on its quad-cadre i5s, only the 7th generation quad-cores didn't have Hyper-Threading at all. The new chips do.

Intel's mobile revamp mirrors product and price changes the visitor has already introduced. For the past six years, Intel has followed the same basic processor philosophy: In mobile, dual-cadre processors were the norm at every level, with simply a few quad-cadre / eight-thread chips available. These accept e'er occupied the top of the production stack and typically been offered only in college TDP brackets. These new chips modify all that.

Performance Scaling Even so Unknown

In that location'southward a chip of mixed messaging over how much performance these new cores will offering. According to Intel, it expects a 40% overall improvement, with 25% coming from the addition of 2 more cores. 'Blueprint' and 'Manufacturing' also add to the total, admitting in smaller amounts. But that's actually less performance than nosotros'd expect to meet, given that doubling core counts from a dual CPU to a quad CPU can drive more than 25% improvement on its own in desktops. Most modern applications calibration adequately well, up to four cores / viii threads, and while that'due south non an absolute, the 25% effigy is still lower than expected.

CoreImprovements

There are several potential answers to this. 1 is that Intel is being conservative and publishing numbers it knows it can back up in almost all circumstances. The other is that Intel has to pull its Turbo clocks down to stay within a 15W TDP. This would be directly implicated if the boost clocks on the 8th-generation CPUs drop significantly as core loads increase. Every bit the table below shows, however, they don't:

Clock-Chart

As you tin can come across, this nautical chart suggests that Intel has set fairly aggressive Turbo Mode clocks for these cores. Just how theoretical these core clocks are remains to be seen. Intel began offering OEMs more flexibility to hit their TDP and performance targets several years ago, merely doing so created odd performance dips and spikes. In several cases, the lowest-end Core M you could buy actually yielded ameliorate operation than the higher-end chips due to thermal problems. Whether or not that will occur here is something we can't approximate until products take shipped.

What's Adjacent for eighth-Gen Core?

Intel has announced that information technology volition launch its side by side generation desktop processors "in autumn," but those of you hoping to drop a half-dozen-core i5 or 12-thread i7 into an existing system are out of luck. The Coffee Lake refresh volition crave 300-series chipsets, and will not be backwards compatible with existing products. Given how lilliputian time it's been since Intel introduced Kaby Lake, the quick hop from the 200-series to the 300-series won't sit down well with people who just upgraded to the 7700K, specially if the desktop eighth-generation cores make 6 cores available for the same price Intel used to charge for four.

All the new chips

Intel may not accept great options here. Semiconductor designs and products tend to have longer lead times than the public is enlightened of; it'southward not unusual to see someone on LinkedIn who worked on a given product a twelvemonth or more before it ships. Intel's eighth-generation Coffee Lake chips are undoubtedly aimed at plugging the hole chips like the 1600X blew in its product family. Kaby Lake would've been completed before much data on Ryzen was available, and Intel's various production milk shake-ups this year have been a response to information technology. AMD's Ryzen desktop family unit continues to sell well, with 7 SKUs in the Top xv CPUs co-ordinate to Amazon.
