Ryzen 2 appears to be completely competitive with current products from Intel.

I suspect the Intel advantage in Passmark single-core scores is not real, because it doesn't seem to be corroborated by any other benchmarking. There is a newer alternative to Passmark.com called UserBenchmark.com which looks a bit more consistent to me when comparing historical CPUs.

Coincidentally, as of December 2018, I cannot buy most Intel CPUs. I imagine that whatever they are able to make is going to Dell, HP, Lenovo, etc. So AMD now completely dominates retail sales of component CPUs. I haven't built anything for quite a while, but the 65W Ryzen 5 2600 looks pretty good: 6 core (with 12 threads) that appears to outpace any 6-core Intel i5-9xxx for less money to boot (~US$165 in Aus). The 90W 2600X doesn't seem to add enough extra performance to justify the significantly higher price and power consumption.

Motherboards seem cheap, what's not to love?

Have all those performance robbing malware fixes been resolved?
I was thinking about a new system next year since 2018 was so messed up.
I'd hope we have 8 cores at 5GHz with some aquatic.

I just built a Ryzen 2700X on ASrock x470 Taichi motherboard with 32GB Corsair 3000MHz for my girlfriend as her new photo editing workstation. I'm almost done stress testing it and getting everything setup and so far it's really nice.

Ryzen 2700X: $269.99
ASrock x470 taichi: $164.00
Corsair LPX 32GB DRAM 3000MHz C15 Memory Kit (2 x 16GB): $249.99
Noctua NH-D15 SE-AM4: $89.90
Noctua NF-A14 PWM chromax.Black.swap Premium-Grade Quiet 140mm Fan: $24.90 x 3
HP EX920 M.2 1TB PCIe 3.0 NMVe: $161.49
Fractal Design Define R6 Blackout Brushed Aluminum/Steel ATX Silent Modular Tempered Glass Window Mid Tower Computer Case: $167.95
SeaSonic Electronics Prime Ultra Gold Series 750W 80 Plus Gold: $120.56
Arctic Silver 5 High Density Polysynthetic Silver Thermal Compound: $15.43
HGST Deskstar NAS 3.5" 8TB 7200 RPM: $229.99
Repurposed Nvidia GTX 780 GPU from an older gaming system
Windows 10 Pro: $40 (from my friend who gets the family discount)

~$1585

I'll be moving over 6 other hard drives and SSDs from her other workstation. I also have a Samsung SM1715 1.6TB NVMe with a x4 PCIe controller to add to this system as a process drive.

AMDs CPUs weren't vulnerable to Meltdown, only some the Spectre variants, most of which performance loss due to mitigation were minor.

My only concern with Ryzen are the mobile parts, and how AMD has handled the driver situation with them...

As for 8core @ 5GHz, IBM has had that covered since 2014 with POWER8. (POWER8 available in 4,6,8,10 and 12 core variants, ranging between 2.5GHz and 5GHz, w/ 32 channel DDR3/4 memory interface). IBM and Tyan both have bare-bones servers based on the architecture...

Were Ryzen CPUs ever *not* competitive with Intel?

It just seems like Intel has continued to bungle it while AMD is hitting all of its targets, making the situation a lot more clear. Also, Intel couldn't price a processor competitively if its life depended on it.

The forthcoming Zen 2 based Ryzen 3000 series chips have my interest. The rumor mill is building. They showed off a prototype 8-core/16-thread Zen 2 based Ryzen 3000 at CES that was performing equal to the Intel i9-9900K in Cinebench while using less power to do it (133W vs 179W).

I'm genuinely interested in their new Ryzen 3000 release for my next build also.
I wonder if they're really going to release a 12C/24T 5GHz (boost) 3700X or the 16C/32T 5.1gHz (boost) 38050X per the rumors. I think the chips are probably likely in some configuration similar to the rumors, but that the rumored pricing is not accurate. $329/$499 for those core counts and speeds seems unlikely to me. They'd basically be doubling the number of cores as the 2000 series Ryzen chips + another 20% boost from the faster clocks at about the same price as the 2000 series.

Maybe they really want to plunge the knife into Intel's mainstream CPU business. I'm not sure.

I feel like, if AMD thinks that they can make money with it, they will release the higher core-count products. They don't care about undercutting their own HEDT products any more than they did about HEDT undercutting workstation/server.

However, throwing on that second chiplet will not be a cheap thing.

16 cores seems like a lot for only 2 RAM channels or does the 300 series have a work around for the RAM limitation?

I don't recall there being room on the chip to expand to 4 channels of memory so it might indeed be an issue for performance. Perhaps that would be the one of the features and benefits of going with a Threadripper over Ryzen 2 3000 with higher core counts like 16+.

Plenty of folks have 8 core/16 thread chips with 2 memory channels without running afoul memory bandwidth. So, in most cases, it can't be terrible to run 16 cores out two channels.

At least each chiplet will have equal access to the memory, unlike the four-chip Threadripper 2000 CPUs.

Many of the discussions and benchmarks I've read show that existing Ryzen CPUs benefit somewhat significantly from faster memory. Adding 8 more cores to the same memory controller may end up showing little performance return on specific tasks that are high in parallel processing. Tasks that benefit from multithreading that are storage IO limited might offer improvements.

I hope I'm wrong and it works great. That would make me wonder why Threadripper has four memory controller.

Mainly I don't want a slower/hotter CPU in order to have more than 8 cores, which reach diminishing returns with a single program anyway. I don't operate a server or have any reason to need all those cores. I would like as much RAM as feasible. My 4+ YO PC has 64GB. Can I get 128GB with the dual channel RAM in these new chipsets?

I'm pretty sure that this has to do with which parts of the 1000/2000 series chips is linked to the RAM clock. If I recall correctly, the Infinity Fabric speed is linked directly to the memory clock. So, faster RAM makes crossing CCXes faster.

Product differentiation? Four is "half way" between the standard two of desktop and the eight of workstation/server.

Yup yup. Infinity fabric speed is exactly the same as actual RAM clock, so say you've only got DDR4-2400 -- it only runs at 1200MHz where at 3200 it'll run at 1600. It doesn't sound like such a huge leap until you figure that's probably the main bottleneck of this setup anyway.
