6c/12t hyperthreading vs 6c/6t and 8c/8t in the near and coming future?

feels hard to decide between for example 8700k and 9700k , do you think the 6c/12t of 8700k will be more and more useful in game engines as they develop, or will the 2 extra real cores on 9700k always be better no matter what?



do any games today leverage and fully utilize for example a 8700k and its 12 total threads? does the 9700k beat it every time? also how do you see 6c/6t cpus like 9600k holding up in these circumstances/scenarios with future/most recent games, I think I read that latest unreal engine can leverage more than 8 threads, but not sure if thats correct and if for example a 8700k would perform better than a 9700k in that case, on the same clockspeed for example?



appreciate any thoughts and comments on this !

I'm in the same boat currently, but strongly leaning toward the 9700K. That said, I think it's useless to try and speculate as to what will happen down the road. Right now, and likely over the next few years, there are trade-offs between the two depending on the particular game or app, rather than one being full-stop 'better' in performance. Some like more cores, some like more threads. This isn't going to change any time soon.

The main distinction here is that the 9700K has a bit better temps (esp. if OC'ing) and power efficiency, and has hardware-level patches for some (not all) of the Spectre/Meltdown stuff instead of OS-level. If that matters to you, go for it. The 8700K is undoubtedly a better value overall, but runs a bit hotter and Spectre/Meltdown patches are implemented only at the OS level.

I'm actually heading the other direction; I'm thinking about getting an R5 2600 with the intention of upgrading to Ryzen 2 when it is released. It's the best of both worlds, and it offers an upgrade path, too.

Short answer: in gaming the 8700k and 9700k are going to stay neck and neck.

You'll be ready to upgrade again by the time that stands a chance of changing. HT has always shown marginal gains and sometimes even slight losses in game performance, a new game engine isn't going to come out in the next year or three that suddenly changes that hugely IMHO. So the 9700k should remain the better (though in terms of FPS... not much) CPU from a gaming perspective.

If prices were the same or price is no concern: get the 9700k.
If the 8700k is much cheaper: get the 8700k, assuming this rig is purely gaming..
if you want the best of gaming and tasking or want to be patient: wait for AMD to drop the new generation of ryzen in the next few months. I'm hoping that results in 9900k performance coming down to a reasonable price, since it's obvious the 9700k was gimped in order to mark up the HT model to $500.

I'm waiting a few months. But honestly, nothing is going to come out that brings game FPS up drastically, so pick your poison.

To be honest an 8/16 will soon be the new low end. What Intel offers right now is simply not worth it at all unless you want a dead platform with no upgrades, outrageous prices for that extra 5-10% of performance.

8700K should not even be considered unless you're buying it 2nd hand cheap.

From a value perspective Intel is dead long dead.

The i7 8700k and i7 9700k are neck and neck in gaming. However, with the games out now the 9700k has about a 3% lead in gaming with GTX 1080ti running 720p. Intel Core i7-9700K Review LINK: https://www.techpowerup.com/reviews/...7_9700K/4.html

8700k would need to be delidded for overclocking whereas the 9700k doesn't. Not sure how good the binning is the 9700k, but my 9900k could do 5.2ghz with no ht on my old motherboard; it might be able to do 5.3 on my current one. The average 8700k will need to be delidded to do 5.0 ghz and will max out at 5.1ghz around 1.4v.

I see, just out of curiosity, would the 9700k at stock 4.6 ghz/8 core turbo be cooler than the 8700k stock 4.3 ghz/6 core turbo loads?
