    Looks like AMD are readying a Zen 2 (Matisse) refresh for release sometime around July (7th?).
    • AMD Ryzen 9 3900XT supercedes the 3900X
    • AMD Ryzen 7 3800XT supercedes the 3800X
    • AMD Ryzen 5 3600XT supercedes the 3600X
    These new parts will be clocked slightly higher due to a more refined and matured 7nm process.
    Offering roughly an 5-10% performance uplift over the older SKUs.

    Price reductions can be expected on the lower clocked X variants.

    This is no doubt a counter move to make Zen 2 even more competitive against the newly released Intel 10th gen Comet Lake-S CPUs which has reaffirmed Intel's FPS gaming crown.

    Unconfirmed XT clock speeds

    3900XT - 4.1Ghz base (+300) / 4.8Ghz boost (+200)
    *3900X - 3.8Ghz base / 4.6Ghz boost

    3800XT - 4.2Ghz base (+300) / 4.7Ghz boost (+200)
    *3800X - 3.9Ghz base / 4.5Ghz boost

    3600XT - 4.0Ghz base (+200) / 4.7Ghz boost (+300)
    *3600X - 3.8Ghz base / 4.4Ghz boost

    --------

    I will update and add information as it becomes available.

    If a rumour from 2 weeks ago is true, these are made on N7P like the console APUs.
    So 7-10% higher clock speed on the same power envelop like the current CPUs is expected.

    Which means 4.9-5Ghz 3600/3800/3900 CPUs. Heh I would trade the 3900X to put my hands on the 3800XT just to tweak it.

    Eek, better watch that they don't flood and confuse the market.

    this is why they should have left the 3rd digit free to allow new models between parts... like a 3650x, rather than 3600XT... silly. I wonder if this means we wont see Zen3/Ryzen4000 this year

    Wasn't really expecting this from AMD to be honest.
    But it's a nice little bonus for people planning a budget B550 build over next few months before Zen3 lands.

    Seems a bit odd having a gpu naming convention attached to CPU's, "xt". Still i suppose it differentiates them from the previous iterations.

    Was considering a 3900x, might snag the xt if its a decent little bump up, and assuming its x370 compatible.:)

    Going to be interesting to see what happens to prices. Soon there will be 3900X, 3900XTb and 4900. Looks like decent performance will be working its way down the pricing quite quickly.

    I must resist changing CPU until AM5 releases :D I'm really interested to see what happens on the GPU front.

    Im on a 3800x, one things for sure, if AMD can afford to add another 5-10% performance on a small refresh i hope it means the 4800x etc has a good 15% ontop of that or they just wot be attractive for 3 series users to move up, especially if you own a 3800XT etc.

    So im thinking if this respin adds another 8% perf ontop, then the 4 series later this year could also be quite spectacular

    I was thinking along very similar lines. One of the issue with AM4 is it's so tempting to drop in upgrades that you don't really need ;) Need to just keep saving my money and wait for the right time to drop in a 16C 4000 series chip. That'll see me through until I've paid off my mortgage :)

    I am surprised those early rumors about a Zen2 refresh seems to be true but if they can launch these alongside the B550 boards, what little momentum intel could have gained in the DIY market would probably vanish.

    Good point. Anyone buying in now has some nice choices. New refreshed chips or discounted but still great performing previous ones all with access to PCIE 4.0 and reasonably priced motherboards. A good saving over what I paid for my Aorus Master and 3700X on release.

    I might be tempted by a 3600XT to replace my 5820k, I'll have to see 1080p benchmarks first though.

    Kind of pointless if it is just a speed bump, you won't see any meaningful difference in gaming, but might see lower prices on the older stuff and AMD gets more attention.

    AMD just trying to keep the pressure on and not give up the initiative

    Going from 4400Mhz-4600Mhz to 4800-5000Mhz yeah there would be difference in gaming.

    Just putting the nail in the coffin for Intels 10th gen - it's embarrassing theyre still churning out 14nm whilst AMD are improving their 7nm.

    A 3900xt boosting to 4.8 or more would be a pretty heavy hitter.

    I cant help but think if this refresh had been from intel it would have been a "new generation" on a new socket :D

    That's exactly what 10th gen Intel is pretty much! Apart from a core count increase and a shift in the stack, the rest is basically 9th gen with a bit more clock speed squeezed out of it.
