Like a quad core i7 that's been working out. Making those hyper threads into real threads. 

You could say it's threadripped

Get out!

Maybe in extremely rare situations.

In best case scenarios using typical consumer programs (I use "typical" very loosely here) the performance benefit of SMT is around 20%. Usually less.

 

So:

6 cores 6 threads = 100% performance (baseline).

6 cores 12 threads = 120% performance.

8 cores 8 threads = 133% performance.

 

On top of that, the benefits of more threads usually becomes smaller and smaller, the more threads you got. It is easier to find programs properly and evenly using 8 threads than 12 threads.

 

I expect the 8 core no-HT processor to whoop the floor of the 6 core 12 thread processor in 99% of all programs.

Might perform better in a given program but I would still expect the 12 threads to deal with multitasking better than 8 threads even if they are all real ones

I'll be interested to see how the 9900k compares to my 7820x at 5Ghz...

I'll probably make the jump if the ring cache's latency is much better than the mesh.

Considering dual channel 9900k vs quad channel 7820x, the latter will outperform the former in certain situations.

but only certain, in others not.

But its also possible that both are basically the same but one with dual channel.

We don't know much about the architecture yet.

I get nice bandwidth on x299, but even with a lot of tuning the latency was never great...

Anyone know the socket type for the 9900K and 9700K?

I think it's either gonna be another coffee lake situation (same socket, different pinout) or a whole new socket, the latter is more likely imo now that we have the i9 in mainstream.

But why do you expect that?

Extra threads isn't really anything magical. It's just a way to utilize the physical resources slightly more efficient.

My 20% number is taken from real world applications such as video encoding, and with a small number of threads (more specifically, core/thread of 4/4 vs 4/8).

 

The extra threads should give 20% in the multitasking scenario you're talking about, if you're lucky.

The extra cores should give 33%, and it should give that performance far more consistently too.

I've seen HT throughput benefits in the range from 0 to 50% excluding a specific synthetic benchmark. A 6 core processor with HT could behave like a 6 to 9 core processor without HT. Sometimes it could be faster than 8 real cores, but most of the time it wont. Just buy whatever works for your price and use case. If all you care about is thread count, get a threadripper already.

Yeah.....I'm just gonna wait

Since Intel's Z390 chipset will support the 9th gen CPUs AND be (allegedly) compatible with 8th gen chips the socket will stay the same old LGA1151 and pinout won't change either (they might use some previously unused pins though since not every pin is always being used on a socket). The smaller 9th gen chips might (!) even work on Z370 boards. We'll have to wait for confirmation. This is (just) a refresh and not a whole new platform.

I believe Z390 is just what would have been Z470. I read somewhere that Gigabyte accidentally confirmed that 9th gen chips will work on Z370 and 8th gen on Z390, but you just won't be able to overclock as far on Z370.

Well, a 9700K clocked to 5.5Ghz does 250 cb single core, with low clocked memory.

@ 5Ghz, that would be (calculated) 227.27 cb

Results may be quite similar until RAM on 9th gen is overclocked properly for benchmarking.

Usually I'd agree, but the 9th gen is rumoured to have hardware fixes for Spectre, Meltdown, and related vulnerabilities.  That could make a significant performance difference in some applications - hardware fixes are usually faster than software fixes.

I sincerely doubt this rumor, as CPU architectures are in development for years before production.  Given that Intel, et al were only informed of the vulnerabilities a year ago, I highly doubt they had time to implement any significant changes to the architecture in that time frame.  Also, I heard/read somewhere (I believe it was a GN video) that these are simply 8-core Coffee Lakes, which means they're likely no different architecturally from the current 8th gen CPU's.

Avoiding being hit by exploits just takes common sense most of the time.

As I've said before, the first line of security on a computer is the user.  The AV/firewall/etc is simply a fall back in case something slips through.

I wouldn't say that, necessarily.  No one is perfect, and there's always a possibility of something slipping past you.  It's like walking a tightrope, would you pay a little extra to have a net below, just in case, or would you rather save some money and hope you don't ever slip?

When i used windows i always had an AV, but it (literally) never had any job. (Most of the things that could trigger it was probably got blocked by noscript and adblock .)

I guess we'll see.  It takes 5.1Ghz to get 227 out of my setup...

Czech retailer posted some more info about coming 9th gen Intel CPUs. The information contains price, frequencies and also which of the CPUs will be soldered and which not.
Here's chart that sums it all up

About the price. This includes tax, in euros without tax it'd be:

i5 9600K 240€   ≈  $250??

i7 9700K 350€   ≈  $350??
i9 9900K 450€   ≈  $450-500??
I am just speculating about the price in USD, not sure how much different the price will be in the US.

If this is true, we can see, that soldered IHS is really making a comeback. However, it's interesting that the i5 will be leftout and will still use paste. It's shame. The i5 is really great mid range CPU and many people would benefit, if it used soldered IHS.

If I am late, then sorry. I read few articles here, but the prices were higher than what I found and there is also a chart which also shows which CPUs are soldered

[The_Tron]

Oh, OK that is some new news I think. In that case you aren't late but maybe try changing the title to say this is an update?
