AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

As a tech nerd, I would love to have them release the CPU's ahead of the boards, but I suspect that might not give them the best showing.

Can't see it making any real difference to be honest, the x370 and x470 make little to no difference on the high end versions of each board, in fact my friend gets better Cinebench scores than I do on his x370 Asus board, which I put down to his chip being better than mine (both 2700x) as he can get 4.3ghz at 1.375v :(
 
Looking like this is going to be a nice little upgrade from my 1600 I'm running with a modest OC at the moment. I'm thinking the 3600X this time, going by the rumours that its now an 8 core plus a nice IPC and clockspeed bump. Just hoping my GB Gaming 5 X370 board plays nicely with it :)

The main issue will be existing boards don't support PCIe 4.0, which will be a fairly major selling point of the new chips, so I don't think it'd work terribly well from a marketing point of view to say "buy these new CPUs, they have PCIe 4.0...but you can't put them in anything to use that feature yet". From a power perspective I imagine everything will work fine on existing boards, at stock speeds at least, unless TDPs are going up for the 12/16 core variants (which could always launch later anyway, once yields are better for example).
 
I am on stock cooler so not really clocking it that high on my 1600 at all. 3.6 to 3.7 all core if memory serves. Either it is a bad chip, or I stuck an OC'ing Ryzen. A stock high frequency chip with 8 cores upwards I would love.

There was a comment recently from CES that they believe its possible to push PCIE 4.0 over existing motherboards that had copper traces under a certain size or length or something? pretty sure i read that it would be possible to update some existing motherboards bios with this.... Interesting if true and would solve the issue of getting chips before boards for early adopters.

I read similar on AnandTech's write-up of the Keynote. Essentially PCI-E 4 signals can only travel 7 inches before needing a redriver, but since the 1st PCI-E slot is within that 7 inch limit, it's feasible that a BIOS revision could allow for PCI-E 4 on that slot.

One of the differences with PCIe 4.0 is that it can only handle PCB traces up to 7 inches before needing a redriver/retimer, so these extra ICs are needed for ports lower down the board. But, the first PCIe slot on most motherboards is in that limit, so it would appear that a lot of current 300 and 400 series motherboards, assuming the traces adhere to signal integrity specifications, could have their first PCIe slot rated at PCIe 4.0 with new firmware.

So in theory AMD could launch some of the bigger SKUs earlier than X570 motherboards in the belief that the chunky beasts like a Crosshair can be PCI-E 4 certified on the top slot, so the enthusiasts and early adopters can jump on the CPUs now and then grab the new boards later (because they were always going to grab new boards anyway). And if you only want the MOAR COREZ then you can still jump early if your VRMs are up to scratch (which the motherboard vendors can cover through selective BIOS updates).

I think really it's only binning and inventory preventing a more traditional March/April launch for Ryzen.

Most likely, but if you're patient and just wait im almost certain a stable bios update will come out within a reasonable amount of time and you can update it then

I actually suspect that an early launch would be strongly supported by the AMD partners & manufacturers, as it would allow them to clear older high end inventory at good prices before being forced to drop them when X570 launches. As such, I'd bet they would be very eager to push out BIOS updates to support the new CPU's sooner rather than later, especially since the low end boards would likely still work fine with the low end CPU's that would be launched further down the line.

Hopefully. :)
 
Great video by Jim as always.

I'm really excited for Zen2 still. I think there's a lot more to come yet. The fact that it beat Intel with such low power usage on what we assume is a mid range chip is nothing short of amazing
 
In all honesty, it all sounds too ludicrously good to be true, and the scary thing it, that probably means it is true lol.

Mid range chip on gimped ram smashes competitions best chip while costing half the price.

As it's been said If the above is true, Intel are going to need some kind of JuJu ASAP to get over this lol
