So, how they measure up to one another? Laptops with Ice Lake CPUs have just begun to ship out at the end of the summer, with plans to release as many as 35 different models powered by Ice Lake by the end of the year. Both Ice Lake and Comet Lake will find their way into products within months of each other and in many cases, may compete directly with one another for user interest and dollars. But they have distinctly different technologies powering them, most notably when it comes to their underlying architecture.
The Sunny Cove architecture that powers Ice Lake CPUs opens up a number of new instructions which can significantly accelerate legacy code by encouraging parallel operation.
It also lowered effective access latencies and enhanced the cache over older core designs. It also supports faster memory than previous architectures up to 3,MHz without overclocking.
Comet Lake is a little different. It will, however, benefit from a new series chipset, which introduces features like support for Thunderbolt 3, Wi-Fi 6, Bluetooth 5, and USB 3. On the laptop front, both Ice Lake and Comet Lake are much more fleshed out and realized with official announcements and specifications right from Intel itself. Indeed, while desktop Comet Lake and Ice Lake desktop chips may be a year or two apart, Intel plans to sell Ice Lake laptops right alongside Comet Lake laptops, with tens of devices with either CPU line in them hitting store shelves before the end of That might make the market for Intel laptops rather confusing, but it does mean there are plenty of options for potential buyers out there.
A noticeable change over previous generations of Intel mobile chips are the increased core counts and clock speeds. Outside of the die shrink and architectural changes, there are some obvious specification differences between these two CPU lines which hint at how they might compete head to head in certain scenarios. Clock speeds are much higher on Comet Lake though, highlighting the problems Intel and AMD have faced in getting high frequencies out of 10nm and subnm components.
That may mean that Comet Lake performs better in some scenarios where clock speed can make a big difference — certain games and software applications may be stand outs there.

Intel may be gearing up to retire its Kaby Lake-X line of processor chips, according to the latest rumours, which also suggest that the Skylake-X platform will receive a refresh later this year.
Quite frankly, that is not too soon in our opinion as we have never been exactly sure of who Kaby Lake-X was produced for. KBL-X seemed to be more of a knee jerk reaction to Ryzen. The rumours also suggest that Skylake-X could receive a refresh later this year - although this will not include changes to the architecture.
The Skylake-X will not feature any architecture changes. The suggestions are purely rumours at this stage, however, with Intel yet to announce any such moves for its Kaby Lake-X and Skylake-X platforms. Intel has now released fresh patches to fix the Spectre variant 2 vulnerability faced by its Skylake, Kaby Lake and Coffee Lake processors.
The bug allows attackers to access system information by manipulating CPU behaviour and has been a cause of concern for customers since it was discovered last year. In a news release last month, however, the firm said its latest batch of microcode updates are stable and now in the hands of manufacturers - with some having already begun rolling them out to customers.
Intel added that patches for older Broadwell, Haswell, Ivy Bridge and Sandy Bridge processors are also on the way - and advised users to ensure their systems are always up-to-date in order to stay protected. Finally, sitting at the very top-end, the core Core iXE processor offers up a base clock speed of 2. The SKU also boasts Consumers can get their hands on a Core iX from 28th August, Intel announced, whilst those seeking the 14, 16 or core SKUs can do so from 25th September.
Unveiled at Computexthe brand new Intel Core iX range becomes the first with an core, thread desktop processor available to consumers. As reported by Tech Radarhowever, the first version of the i X-series will sport 10 cores, 20 threads and will arrive with a base clock speed of 3.
It includes Intel Turbo Boost Max technology at 4. Intel's new 7th-generation Kaby Lake processors will hit the channel next month, the company has confirmed. Devices like 4K laptops and convertibles containing the company's new CPUs are expected to be available from OEMs starting in September, ramping up to include more than different models by Q4 More processors will be released in January, including chips for enterprise users and workstations, and high-end gaming SKUs.
Kaby Lake will power a range of feature-rich designs, the company said, including more than devices with support for the Thunderbolt 3. The company is putting a strong emphasis on mobility, with ultra-thin detachables, convertibles and clamshells, including notebooks thinner than 10mm. Intel is also boasting of double-digit performance increases over its 6th-gen chips for productivity and web performance, thanks to processor and CPU optimisations.
Earlier rumours had suggested a possible Q2 release for the processor chips but Techfrag reports that a later release is more likely. Citing information from Benchlifethe website also adds that both the Skylake-X and Kaby Lake-X enthusiast chips will both be launched at the same time and will be based on the 14nm processing node. The Kaby Lake series, however, will receive 4-core chips and aimed at consumers with a lower budget.
The 4-core core chips also means that only Core i7 and Core i5 models will be produced. Skylake-X will include quad channel memory support, whilst Kaby Lake-X will feature dual channel. Following the initial rumours of a Skylake-X and Kaby Lake-X arrival in Q2fresh details have emerged revealing some exciting developments.The following explanation of IPC has been previously used in our Broadwell review. Being able to do more with less, in the processor space, allows both the task to be completed quicker and often for less power.
Intel Takes Entry Xeons Up To Coffee Lake
While the concept of having devices with multiple cores has allowed many programs to run at once, purely parallel compute such as graphics and most things to run faster, we are all still limited by the fact that a lot of software is still relying on one line of code after another.
This is referred to as the serial part of the software, and is the basis for many early programming classes — getting the software to compile and complete is more important than speed.
But the truth is that having a few fast cores helps more than several thousand super slow cores.
This is where IPC comes in to play. The principles behind extracting IPC are quite complex as one might imagine. Ideally every instruction a CPU gets should be read, executed and finished in one cycle, however that is never the case. The processor has to take the instruction, decode the instruction, gather the data depends on where the data isperform work on the data, then decide what to do with the result.
Moving has never been more complicated, and the ability for a processor to hide latency, pre-prepare data by predicting future events or keeping hold of previous events for potential future use is all part of the plan. All the meanwhile there is an external focus on making sure power consumption is low and the frequency of the processor can scale depending on what the target device actually is. For the most part, Intel has successfully increased IPC every generation of processor.
As Broadwell to Skylake is an architecture change with what should be large updates, we should expect some good gains. From a pure cache standpoint, here is how each of the processors performed:.
Between 4MB and 8MB, the cache latency still seems to be substantially lower than that of the previous generations. Normally in this test, despite all of the CPUs having 8MB of L3 cache, the 8MB test has to spill out to main memory because some of the cache is already filled. It seems that the latency in this region is a lot higher than the others, showing nearly clocks as we move up to 1GB.
But it is worth remembering that these tests are against a memory clock of MHz, whereas the others are at MHz. As a result, the two lines are more or less equal in terms of absolute time, as we would expect. Dolphin Benchmark: link.
Many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance.
This benchmark runs a Wii program that raytraces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU.
Results are given in minutes, where the Wii itself scores Cinebench is a benchmark based around Cinema 4D, and is fairly well known among enthusiasts for stressing the CPU for a provided workload. Results are given as a score, where higher is better. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores. For a brief explanation of the platform agnostic coding behind this benchmark, see my forum post here.
Compression — WinRAR 5. We compress a set of files across folders totaling 1.Intel's steady cadence of iterative updates have improved frequency over the years, and that has boosted performance in common, lightly-threaded applications.
But the arrival of AMD's Ryzen has radically altered the status quo. Suddenly, AMD CPUs have more cores to tackle more taxing workloads, and those processors come at a significant price discount. Now, Intel is firing back. AMD still holds the core advantage. Intel's top-end parts wield only six cores compared to Ryzen's eight, but Intel leverages its per-core performance advantage, a combination of both IPC throughput and frequency, in this battle.
AMD will respond next year with the 12nm LP processbut for now, the Coffee Lake and Ryzen lineups go toe-to-toe in a fight for enthusiast dollars. One of AMD's biggest advantages comes in the form of looser market segmentation practices.
The company offers an unrestrained feature set that includes unlocked multipliers on all models and supports overclocking on value-oriented motherboards.
Nevertheless, we didn't expect Intel to stray from its notorious segmentation with Coffee Lake, and the company met our expectations by continuing to charge a premium for unlocked "K" SKUs.
Surprisingly, the company added a relatively small premium over Kaby Lake models to the "K" SKUs to offset the increased core counts, but the MSRP deltas between the two lineups are still slim.
You have to check pricing frequently to find the best deals. The Core i7 and Ryzen 7 products serve the vast majority of high-end enthusiasts, and both lineups feature threaded cores. AMD still holds the unequivocal lead with eight cores and 16 threads slugging it out with Coffee Lake's six cores and 12 threads. Intel's Coffee Lake processors take a step back in base frequency compared with Kaby Lake, necessitated by the thermal challenges associated with adding more cores within the same package, and this erodes some of the company's frequency advantage.
Intel still holds the advantage of higher base frequencies, albeit by a slimmer margin. However, the company relies on its Turbo Boost feature to increase performance when all the cores aren't needed. That gives Intel a MHz boost frequency advantage, but due to the sometimes finicky nature of boost behavior, we'll have to put the processors to the test to decide if that equates to a win in the performance department.
Both processors feature dual-channel memory. Of course, memory performance is more nuanced than numbers on a spec sheet. Latency and throughput are crucial factors, so testing will give us a deeper understanding of performance. The Ryzen models also come with a more generous helping of 20MB of L3 cache. They're fundamentally the same. Nevertheless, Ryzen processors lack the feature entirely.
Although we strongly discourage it, the majority of users still roll without discrete graphics cards. AMD's Ryzen 7 products both admirably feature unlocked multipliers, but due to Ryzen's relatively mundane frequency ceiling, overclocking headroom has been Intel's key advantage with the Kaby Lake series.
We'll have to see if that advantage holds with Coffee Lake, but according to Intel, we should see a similar story play out thanks to Coffee Lake's power delivery optimizations.
Intel's all-core Turbo Boost frequencies, which the company no longer officially lists, also tend to move beyond Ryzen's all-core overclock frequencies. We'll quantify those frequencies in our review. Both series feature similar TDPs, although it's noteworthy that the Ryzen 7 comes with an excellent bundled cooler that allows for solid overclocking, whereas Intel's stock coolers just aren't of the same caliber.
The iK doesn't have a direct pricing equivalent in the Ryzen 7 lineup. We expect there might be some price manipulations on those models after the Coffee Lake launch, so keep an eye out for deals. AMD retains the advantage of allowing overclocking using less expensive chipsets, whereas you'll need to factor in a Z motherboard to unlock the Core iK's full potential.Release date: Q4 In previous generations, a 6-core processor would have been a high-end desk-top HEDT processor, however the iK is the first Intel CPU with 6 cores and 12 threads to be classified and priced as a mainstream consumer processor.
Specifically, the iK features a base clock speed of 3. A new motherboard will need to be factored into the budget when upgrading to the K as it requires a new Intel Z chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete.
The Core iK is Intel's latest "Skylake" flagship processor. It replaces the hugely successful iK and takes the crown as the fastest mainstream consumer CPU available.
Owners of any unlocked-K Intel CPU from Sandy Bridge or onwards still have no real reason to upgrade as the performance improvements are largely academic but the iK will be the CPU of choice for the vast majority of top end PC builds in We calculate effective speed which measures real world performance for typical users.

Skylake vs. Kaby Lake: Could Intel retire its Kaby Lake-X chips this year?
Ryzen Votes: 54 Coffee Lake Votes: 62 Something Else Votes: 15 Total voters Poll closed Oct 11, Previous Next. Tup3x Senior member. Dec 31, I want to double the core count when upgrading my CPU this time.
DrMrLordX Lifer. Apr 27, 14, 3, I think?Does RAM speed REALLY matter?
Lots of plusses. How many can they add? I don't know. But more is better right? Anyway if you're prepared to deal with a 5 GHz 8c chip heat-wise, there's your chip. My guess is that Pinnacle Ridge will hit 4. Jan 8, 9, 1, DrMrLordX said:. Aug 11, 10, Eric said:.Monday, June 17th Averaged across a spectrum of benchmarks, Intel claims a best-case scenario IPC instructions per clock uplift of a massive 40 percent over "Skylake," and a mean uplift of 18 percent.
The worst-case scenario sees its performance negligibly below that of "Skylake. The comparison to "Skylake" is relevant because Intel has been using essentially the same CPU core in the succeeding three generations that include "Kaby Lake" and "Coffee Lake. At a clock-speed of 3. To put this number into perspective, a Ryzen 7 X "Matisse" supposedly needs to run at 4.
Desktop "Ice Lake" processors are unlikely to launch in Hang on a second there, didn't Intel say they only wanted to use real world benchmarks from now on? That means this is against their own policy and clearly irrelevant, no?
FWIW, Where I have seen this posted elsewhere the general consensus seems to be that this is not genuine. Assume this graph is true. Numbers don't add up. The Intel slide or the Chinese "benchmark"?
The Chinese part. I believe the Intel slide is from Computex. Well, they often aren't so Thus the performance uplift is really small. Yeah, Intel's testing without security mitigations is shady.
And they are comparing these against Skylake which has none of that. When this is tested without security mitigations, Skylake should get a bigger boost than Ice Lake, making the uplift from new cores even bigger when taking security mitigations into account.
I don't know about that. Heads Up- just posted on the News here in Israel: "Intel to suppliers: The establishment of the new plant[10nm] is postponed. As revealed in Calcalist, Intel summoned one of those involved in setting up the factory in Kiryat Gat, one after the other, and announced a delay of at least half a year.
TheLostSwede Hang on a second there, didn't Intel say they only wanted to use real world benchmarks from now on? What does a random person in China have to do with this? This isn't Intel There have been rumors in the past that Intel will skip to 7nm for high end desktops. I hope it is true.
