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

Single threading performance is looking pretty good for the 3600X (in the top 1%). It seems likely the cpus above this model will overtake the 9900k in single threaded tasks, at stock speeds.

In my view AMD has finally caught up to Intel, as single threaded performance is what matter most in games and most tasks.

The killer for AMD will be if the 3600-3700X parts are snapping at the heels of Intel but at significantly lower cost when paired with a B450 motherboard

Definitely this. I'm definitely considering migrating from my Z97+4790K to B450+3700X, the only thing I would be losing is SLI support but that's dead anyway.

Given then there will be no B550, it seems like that may actually be the only option if you don't want to fork out for the X570 boards with PCIe 4.0

I think your money would be better spent with a standard chip & D15/D15S. The way PBO seems to work, you'll get more, price/performance wise with the better cooler.

I have a D15S on my 4790k. A chip notorious for it's heat output, bit like the 9900k overclocked today. I actually get better temps at a lower noise output than the H100i it replaced.

I settled with the stock cooler for the 2700x, but this time I might just be in the market for an air cooler to push my new chip just a bit further. I wonder which air coolers will be best for a 3900x. I've never used an AIO and have been scared off them.

PCI E Gen4 needed more stability, and the Ryzen 3000.
Boards are server grade, more layers = more expense to cope with the signal integrity for PCI E Gen4, simply that.

Yeah but honestly how can anyone suggest that the increase by 2-4 PCB layers from 6 previous gen with chipset and PCIE 4.0 is worth 200% increase!!!

There’s really no reason to be scared of an AIO. They’re great coolers and very easy to install. Not as easy as air coolers, but still easy. I’ll be using a Corsair H100i for my 3900 rig. That will allow me to push it further than an air cooler. Or rather, PBO will be able to push it further.

you can get a D15S for like ~£80. they're 140mm fan and left at stock bios profile work about as well as when set to ~90-100%. They're practically silent, really, and have no fail points other than the fan which has a silly lifespan rating. Any AIO at that price point would be junk. I've just bought a kraken X72 for this (hopefully 3900x) upgrade, but am under no ilusions it'll probably be louder for the same performance.

Don't be scared off AIOs, just don't buy cheap. I had 3 H100i which all failed one way or another, and they were loud. if you want to dip your toe, I'd suggest the kraken x62: https://youtu.be/WJejyyVPNe4?t=348 their noise normalised thermals are second to none. Though you need case space to mount a 280mm cooler

AMD have been quite critical of Nvidia selling RTX with all their latest cards. PCIe4 has the same ring to it TBH.

People don't like being forced to pay for something they didn't ask for, dont need, and can't even use.

You don't have to have X570, Ryzen 3000 is backwards compatible with all previous board's.

I don't see the point of all the fancy VRMs, many layered PCB, super efficient power delivery if the CPU is languishing about at 4.4ghz, usually less and boosting to 4.7ghz annually to celebrate the anniversary of AMDs founding. From all the evidence I've seen this is going to be yet another disappointing launch from AMD. Top line CPU frequency from AMD has recently been underwhelming. With a 9900K you have a fairly decent chance of getting a 5ghz all core overclock with good cooling (it's sold as a 4.7Ghz CPU). With the 2700x you have next to no chance getting a 4.35 all core overclock with good cooling (it's sold as a 4.35ghz CPU). Just shift those goalposts to the 3700X/3800X/3900X and that's where performance will fall. I want to be wrong but I
think even the 3900X at maximum PBO on a 570 £300 is going to be 10% slower than 9900K (at 5ghz) in 95% of games.

You do understand that clock speed by itself isn't everything, right?

5Ghz on one architecture isn't directly comparable to 5Ghz on another.
 
Is AMD's 'Game cache' divided between each CPU core on Ryzen processors?

If so does this mean the 3700X would have less cache per cpu core (36 / 8 = 4.5‬ cache per core) than the 3600X, and could be slower for some tasks?

I also notice that the turbo speed for the 3700X is the same as the 3600X (4.4Ghz).
