We’ve spoken here at AnandTech several times on the upcoming Z390 chipset and also a few words on new processors for those motherboards. Intel has promised a new consumer-grade launch this year, so we are patiently waiting for more information. As it turns out, some retailers get that itch early – in this case, a Vietnamese retailer has listed five processors for sale.
|Intel 9000-Series CPUs|
|Core i9-9900K||CFL-R||8C/16T||3.6||5.0||16 MB||DDR4-2666||95 W||-|
|Core i7-9700K||CFL-R||8C/8T||3.6||4.9||12 MB||DDR4-2666||95 W||-|
|Core i5-9500||CFL-R||6C/6T||3.0||4.3||9 MB||DDR4-2666||65 W||-|
|Core i5-9400||CFL-R||6C/6T||2.9||4.1||9 MB||DDR4-2666||65 W||-|
|Core i3-9100||CFL-R||4C/4T||3.7||-||6 MB||DDR4-2400||65 W||-|
|8th Gen Offerings|
|Core i7-8086K||CFL||6C/12T||4.0||5.0||12 MB||DDR4-2666||95 W||$425|
|Core i7-8700K||CFL||6C/12T||3.7||4.7||12 MB||DDR4-2666||95 W||$370|
|Core i5-8600K||CFL||6C/6T||3.6||4.3||9 MB||DDR4-2666||95 W||$258|
|Core i3-8350K||CFL||4C/4T||4.0||-||8 MB||DDR4-2400||91 W||$179|
There are several key points to gather from the table.
Intel doesn't seem to like multithreading anymore: when the product stack had multithreading and went up to four cores, it was easy to segment. When six core processors came along, there was a mix between 6C/6T parts in some tests being outperformed by 4C/8T parts that were cheaper. The best way to eliminate that issue is to either make all parts have HT, or none of them. Intel has gone for the latter across its stack, except at the high-end with the 8-core part. This might also have something to do with recent side channel attacks, which can take advantage of HT. Removing HT removes the attack vector, although has a knock-on effect in performance.
Intel is moving up to 8-cores: as promised, Intel is bringing 8-cores to the mainstream to compete against AMD’s 8-core Ryzen parts that have been on the market for over a year. Intel will use the Core i7 brand for 8C/8T processors, like the i7-9700K, and then the Core i9 brand for 8C/16T processors like the i9-9900K.
Cache is a commodity: For the 9000-series, it would appear that only the Core i9 will get the full 2 MB L3 cache per core, while all the others get only 1.5 MB L3 cache per core. This will have a knock-on effect as this cache is an inclusive cache, which keeps a full record of L2. In the previous generation, All Core i7 parts had a full 2 MB L3 per cache, as well as the Core i3-8350K and Core i3-8300 series.
Ignore TDP if you want Turbo: As stated several times in the past, Intel's use of TDP only refers to power consumption at the base frequency. It's going to be interesting to see how much power these chips draw under turbo.
Prices were not listed on the leak, and instead users have to contact the retailer. Memory support appears to be DDR4-2666 for all parts except Core i3. Also, all the parts are listed as Coffee Lake Refresh, using a 14nm class process.

ESR323 - Friday, September 21, 2018 - linkReally interested to see if the 9700k will beat the 8700k given fewer threads and a negligible increase in clock speed, assuming this leak is accurate.
milkywayer - Saturday, September 22, 2018 - linkNo HT?
I thought AMD punched them back into their senses but it seems intel wants to milk one last gen before becoming the under dog.
Greed has no limits. Ugh
AutomaticTaco - Monday, September 24, 2018 - linkNo one is forcing anyone to purchase any of these. If you do not care for their price, performance, features or otherwise you simply do not buy one. As for offering options without-HT re-read the article, or others, some Linux distros have disabled HT to prevent side-channel attacks. A bit over-the-top IMHO but still these options provide a guaranteed prevention for those inclined to worry.
milkywayer - Monday, September 24, 2018 - linkThat's a silly argument. No one is forcing anyway, same as nvidia charging $1200 this generation isnt forcing anyone to buy but that was not the point. Read again.
iwod - Friday, September 21, 2018 - linkAll thanks to AMD. 5Ghz Single Core performance is going to be interesting, with all the security fix turned on. We really need some Zen 2 news from AMD before this thing launch.
HStewart - Friday, September 21, 2018 - linkKeep in mind with this series CPU, security fixes are in hardware and not just firmware. So it will be interesting to see performance. No AMD also have security issues and not sure about their updates.
JoeyJoJo123 - Friday, September 21, 2018 - linkAccording to a previous Anandtech article, some of the security fixes are baked into hardware, some are still in firmware. We may need to wait until Intel's next gen series processors for all the fixes to be baked into hardware.
PopinFRESH007 - Sunday, September 23, 2018 - linkI believe you are referring to https://www.anandtech.com/show/13301/spectre-and-m... @HStewart would seem to be incorrect with the statement "with this series CPU, security fixes are in hardware". Coffee Lake and Cannon Lake (+, X, refresh, or otherwise) were not mentioned in that article.
The article specifically mentions the Cascade Lake and Whiskey Lake microarchitectures as having mitigation in hardware for some variants and still firmware based mitigations for Amber Lake. We will more than likely need to wait until the rumored "Cove" processors for all of the variants to be mitigated in hardware.
hansmuff - Friday, October 5, 2018 - linkYou are correct. The upcoming chips do NOT have any additional hardware fixes. Side channel attack fixes will still cost a lot of performance.
0ldman79 - Friday, September 21, 2018 - linkHopefully AMD will make some changes and get higher clocks out of Zen 2.
That's all that's holding them back at the moment and just going to 7nm isn't likely to fix it. We've been able to hit 5GHz since 32nm. Got to be an architectural bottleneck.
