I saw it today all over the place and cannot understand how's news. We knew that it will do support 4000.

Only if each mobo vendor chooses to support it at the time.

I'm not hopeful for MSI X370 support, I would have to use a beta bios as it is just for a 3xxx. Would be nice though!

Why? 4000 isn't out yet, there wouldn't be any bios updated for it either way.

I take it we're expecting the 4950X to be the most powerful CPU AMD will release for X570?

That's my guess as DDR5 will most likely be used at the end of 2021.

So that's the chip to go for if you want the best chip that will ever be available for the B350/X370/B450/X470/B550/X570 boards.

Be nice if Zen 3 was compatible with x370, so far all i've seen is "tbc" when that question is asked.

 

[andy_mk3]

Anyone else find it weird how this time last year there were tons of 3xxx series leaks and rumours and predictions going on, this year absolutely nothing really has surfaced at all.

Probably just depend on the motherboard bios support, so down to individual manufacturers

I'm waiting for these to upgrade my 4th gen i7 (Q1 2013). Going to be a nice upgrade 4700/4800x I think I will go for. So September after Computex yeh.

TSMC have designed 5nm to be "enhanced" on EUV 80% density increase. Might have to upgrade again once that comes lol! Going to be insane. Intel hoping to come back with 7nm I don't think so!

There have been loads of rumours and predictions. Maybe less hype because it's basically just a change to the cores per die, rather than a shrink.

Hoping for a drop in latency, though even if they hit 60ns that's still a bit behind Intel.

Would be nice if they also raise the clocks on the lesser core chips quite a bit.

we're already at 60ns. If you get a decent kit of ram and manually tighten the timings you can get 60ns right now on ryzen 3000. But Intel gets 45ns so still a tad ahead, they need everything they can get

 

[Troezar]

I presume the latency will drop significantly with an 8 core CCX?

Yes to both questions with * (asterisk) on first one. Also the I/O is a brand new much more intelligent and faster one at 7nm.


* If AMD goes for 7nm+ and not 7nm enhanced, with the I/O at 7nm there is space on the AM4 tray for a 3rd chiplet if AMD can wire it. That might be one of the most hilarious moments in CPU history if does so

Fewer hoops to jump through as such, so yes.

But I would never expect it to reach Intel's current desktop level - simply because those monolithic architectures have an advantage here and always will.

Right forgot about that, though 60 is still hard to get, i was able to get 65/66.

How much are we expecting latency to drop to?

Bit disappointing if they can't get very close, does that mean Intel's latency will go up with their new stuff later next year? Or if they are taking a different approach, they might have the lead there again.

The only person that did 60.9 was a psychopath running a 1920 FCLK with CAS 11 RAM. Yes... CAS 11. 1.75v IIRC... aka he's killing his PC for a benchmark.



It's luck of the draw to get 1900 so 3600Mhz RAM at CAS14 should be 65ns but no way a normal user who cares about longevity of hardware can do anywhere close to 60ns.

So you're saying there's potential for a 24 core AM4 CPU? That could be interesting. It does seem like AMD aren't finished pushing up core counts. I wonder what their end game is?

It could leave existing software developers exposed by newcomers with alternative muticore optimised software. Intel look to have nowhere to go with frequency increases. The future appears to be more parallel processing, larger cache sizes, faster RAM and storage to feed those cores more quickly.
