Test Bed and Setup
As per our processor testing policy, we take a premium category motherboard suitable for the socket, and equip the system with a suitable amount of memory running at the manufacturer's maximum supported frequency. This is also typically run at JEDEC subtimings where possible.
It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

The answer is "yes, with a but". Certain things scale really well with hyperthreading. Other things can see a severe regression, as it thrashes between one workload and another and/or overheats the CPU, reducing its ability to boost.Cache contention can be an issue: the i9-9900K has only 33% more cache than the i7-9700K, not 100% (and even if there were, it wouldn't have the same behaviour unless it was strictly partitioned). Memory bandwidth contention is a thing, too. And within the CPU, some parts can not be partitioned - it just relies on them running fast enough to supplky the parts which can.
And clearly hyperthreading has an impact on overclocking ability. It might be interesting to see the gaming graphs with the i7-9700K@5.3Ghz vs. i9-9900K@5.0Ghz (or, if you want to save 50W, i7-9700K@5.0Ghz vs. i9-9900K@4.7Ghz - basically the i9-9900K's default all-core boost, but 400Mhz above the i7-9700K's 4.6Ghz all-core default, both for the same power).

Any chance y'all would be willing to run those HT-bound tests with the 9900K's HT disabled in the BIOS?ekidhardt - Friday, October 19, 2018 - link
Thanks for the review!I think far too much emphasis has been placed on 'value'. I simply want the fastest, most powerful CPU that isn't priced absurdly high.
While the 9900k msrp is high, it's not in the realm of irrational spending, it's a few hundred dollars more. For a person that upgrades once every 5-6 years--a few hundred extra is not that important to me.
I'd also like to argue against those protesting pre-order logic. I pre-ordered. And my logic is this: intel has a CLEAR track record of great CPU's. There hasn't been any surprisingly terrible CPU's released. They're consistently reliable.
Anyway! I'm happy I pre-ordered and don't care that it costs a little bit extra; I've got a fast 8 core 16 thread CPU that should last quite a while.

You have the numbers anyway. Not everyone buys the highest end and then wait many years to upgrade. That isn't the smartest choice because you spend so much money and then after 2-3 years you're just a mid-ranger.For those who want high-end they can still get a 2700x today, and then the 3700x next year with most likely better performance than your 9900k due to 7nm, PLUS have money over PLUS a spare 2700x they can sell.
Same thing for GPU except for this gen. I never understood those who buy the xx80Ti version and then upgrade after 5 years. Your overall experience would be better only getting the xx70 but upgrading more often.

This is what actual logic looks like!Gastec - Sunday, November 4, 2018 - link

Exactly. I think the ones beating the value dead horse are mainly AMD fanboys defending their 2700x purchaseeva02langley - Friday, October 19, 2018 - link
Sorry, value is a huge aspect. The reason why RTX is such an issue. Also, at this price point, I would go HEDT if compute was really that important for me.It is not with 10-15% performance increase over a 2700x at 1080p with a damn 1080 TI that I will see a justified purchase.

Gratuitous trolling, drags down thread quality. Do you really still need to be told what AMD has done for this market? Do you even think this product would exist without them - except at maybe twice the already high price? Go pick on someone that deserves your scorn, such as ...

What a mess. I guess gaming really doesn't depend on the CPU any more. Those Ryzen machines were running at a 1Ghz+ speed deficit and still do decently.Intel needs a new core design and AMD needs a new fab.
