EK 240mm LCS. Not the most extreme cooler out there but definitely mainstream LCS.

Ah that way .. possibly 4 sure. Historically AMD does not like 10 core parts though. No idea what the reason there is. Perhaps yields are simply better than that or cost/benefit wise it might not be interesting enough.

i still get a very strong feeling that non X models will come in few months
maybe has to do with odd numbers per ccx .. although i have no idea if thats the case ... i mean in the past they had no issue to bring 3core cpus ...

I'm not sure what you have in the pipeline @Hilbert Hagedoorn, but if you were looking for some more Zen content then it would be very interesting to see some benchmarks showing how performance scales with different memory clocks and latencies.

Also 5600X with 2 cores disabled. That quad core zen3 could be cheap gaming beast. People need that 😀

Yes please.

It is high binned, AMD just wants to make sure it doesn't outperform the 5900X and 5950X. They don't want people going "HuRr DuRr why should I buy the 5950X when the 5800X is faster in !?"
That's probably why the 3800XT was so stupidly expensive.

HH: At the risk of reposting, there is an error on page 30 in the first paragraph :
"And yes, all die's are the same, so in this proc 2 cores are simply disabled."
That appears to be hold-over from the 5600 review.

This will be my last reply, otherwise i will get a headache from facepalming so hard...
If it was a high binned chip, it would clock as high, or higher than the 5950x... and it doesn't - not even when oc'ed does it reach the stock boost clock of the 5950x.

Yes, thus they dont use high binned chips in the 5800x, unlike in the 5950x.

Seems that facepalming is causing you brain damage. Are you not aware of how Ryzen overclocking works? Not even the 5950X itself can overclock to its boost clock speeds. You're not likely to achieve an all-core overclock at 4.9GHz on Ryzen with off-the-shelf cooling methods. The max boost clock doesn't apply to all cores. That's why when you do an all-core OC, even though you aren't reaching/exceeding the max boost, you're still drawing a hell of a lot more power.
IIRC, an overclocked 5800X draws more power than a 5950X, so yeah, it's probably not going to reach/exceed 4.9GHz on all cores, regardless of binning.
That doesn't change the fact the 5800X is composed of high-binned chips, but like I said (and you seem to ignore) is AMD doesn't want the 5800X topping the charts of their more expensive products.

Bummer about the price, especially since the binning is quite meh. This really should’ve been the 5700X at lower price point.

/massive facepalm
Hillbert overclocked it to 4.7 ghz all core... with off the shelf cooling. But i guess you didnt even read the review, you just went to the comments to spew BS.
And yes, the 5950x can be clocked to 5 gz on a single core - the 5800x cant be clocked to 5 ghz on any core.
Read the link i linked in my first post... it shows that the boost behavior on the 5950x with only 8 cores used is far surperior to that of the 5800x.
And yes, it's because amd doesn't want a midtier product to be top of the table - thank you captain obvious. And that's exactly why they are using the high binned ccx's in the 5950x, and not the 5800x.
My whole point is that amd is missing an oppertunity to make a truly high performance gaming chip by not having a high binned 8 core single ccx cpu that can reach 4.9 - 5 ghz.
I seriously feel my IQ plummeting talking to you...

So needlessly hostile... So much for your "last comment".
Clearly, I was looking at the wrong product and you're not paying attention either, because the 5950X boosts to 4.9, not 4.7. That being said, it can't OC to 4.9 on all cores with off-the-shelf cooling. So, my point remains the same that the 5800X is unlikely to do the same. Yes, the 5950X can get an all-core OC to 4.7. HH managed to achieve 4.7 on the 5800X too, so, the binning isn't as terrible as you think.
There are people who managed to get higher than HH (without extreme cooling). Just because he didn't reach 5GHz, doesn't mean it can't happen. Just because some people got 5GHz on a 5950X, doesn't mean everyone will.
You're the one who's complaining about why they didn't do things the way you wanted. I'm trying to explain it to you, jackass.
It is a truly high-performance gaming chip... Although a higher-clocked single-CCX chip would be nice, Zen3 so far doesn't seem as crippled by multiple CCXs as previous generations. The performance gains for the 5800X don't even make up for the lower clock speed.
I seriously feel you're approached this needlessly aggressively. I already stated that I had a misunderstanding earlier, and you escalated this REAL quick.

Current bigest flaw is .... there isnt any game or GPU that would take advantage of that power. You will see retest in 2-3 years , this will be TOP dog . Watch 720p benchmarks that are well optimized for ryzen . ( soon all new games will be more or less well optmized for ryzen, just like it was with intel for last 10 years) .
- Check some well optimized CPU games ( Strange Brigade , WWZ...)

That's a flaw? Wtf?

5800x, come to me.

My nice new shiny 5800x that I waited outside in 30 degree weather for 6 hours to obtain is defective. Core 4, 5, 6 are not properly connected to the heat spreader and spike to 98 degrees under an kind of load. While the other cores have good thermals and hit a 48.3 to 48.5 multiplier the defective ones barely hit a 12x multiplier. Got a store credit and they will let me know when they get their next batch. Back to the 3900x for now.

Intel just has everyone conditioned into that mindset. I think it just another key difference in their designs. AMD is only making 8 core chiplets, anything that they sell with less is because its somehow defective. If it has fully functional cores that are too leaky, or can't hit the desired clocks, they become 5800Xs. The 3950X and now 5950X both use less power than their x900X counter parts. So the x900s likely suffer from both problems. Besides the lack of competition, the 16 cores are disproportionately more expensive because it's just better silicon. Actually with the across the board price increase, the 5950X is actually less per core than the 5800x. Even then its stuff that isn't up to snuff to be server or threadripper chiplets. At least this time it seems like the dual CCD CPU's are getting 2 equal quality chiplets. You'll probably get exactly what you want in a 5800XT though, if they end up with a surplus of 5950X quality silicon.
