Now which one is the best candidate for hitting 5.0GHz?

i'm wondering if you could take a 3900x and disable some cores to drive the rest higher without too much energy increase.

Not sure the 5ghz leaks should be given much credence. Just as likely IMO this first gen 7nm process will hit a brick wall well south (ie 4.7) like Zen 1.

AMD could be sandbagging with frequencies though. They're def holding back X boost versions, the 16 core AM4 and Threadripper 3k releases until Intel responds with their 14nm+++++ Icelake melters which are supposed to have an ok IPC uplift too. AMD supplies will be short, and they want to max sales of Epyc 8 core chip combinations over Treadrippers and AM4.

I'm all in for the Ryzen 9 3900X at release, should be a great upgrade over a 2700x. Once the 16 core Ryzen 9s come out will decide if the 570X motherboards are worth it (prob not) or just wait for a Threadripper 3000 in 2020.
My gaming rig will love the Ryzen 5 3600X for xmas.
The 2400G htpc might last until something like the rumoured 6 core Zen 2 - Navi chiplet APU is out.

Great upgrades all around. Navi looks to have decent promise unless NVIDIa comes out with a 7nm refresh of their stock. Next gen PS4 and Xboxes should be awesome with Zen 2 and Navi heh.
(edit) aaaaaan lol, Nvidia will not be Live streaming their Super conference.... perhaps they have nothing much ?

The demo'd 9900K w/ 2080ti versus Ryzen 3800X w/ Navi RX5700 was an interesting warning shot. AMD seemed to be saying that their parts will be at optimum performance when board, cpu, and gpu are used together.

Meh I'm a lil skeptical here, IMO just marketing BS. There is no *optimum performance* magic sauce. Besides , that was a bandwidth test irrelevant for *cough*.... a gaming focused part: how many scenarios have you saturate your PCIe bus now? Why do you want 2x bandwidth for your GPU? Yah AMD smoke & mirror bullshit. Reality check: even if AMD Navi efficiency numbers and IPC are closeish to realistic then NVIDIA will still be at least fairly to significantly ahead of AMD instead of the laughably curb-stomping them as they are now (pricing aside). Navi looks like a welcome improvment but not like Zen vs Intel. I doubt NVIDIA will pull an Intel with their GPUs but NVIDIAs troubles long term will be maintaining this level of dominance, tied to manufacturability issues of their designs. Good news for AMD is the performance gap should shrink considerably with a new RDNA architecture, provided Raja did his homework well while he was at AMD. Which brings us to Intel and Rajabee......

Acer President Jerry Kao seemed to be suggesting the same thing when he pointed out that AMD's GPU competition doesn't have CPUs, and AMD's CPU competition doesn't have GPUs (he also said Intel tried and failed, lol).

This is just cringe-worthy smoke and mirrors from AMD though, its Press conference marketing of a second rate GPU division trying to ride on coat-tails of Zen 2 hype. Admittedly, NVIDIA is just screwed with x86 licenses and can only go down (from near total GPU dominance) in *parts* of the market. NVIDIA will slowly bleed some more market share to the integrated APU segment as the chiplet CPUs+GPU+HBM processors come online from AMD and Intel.

The future is integrated CPU+GPU (AMD, Intel) eating (more and more) market share of discrete GPUs (NVIDIA)

NVIDIA growth (not technical dominance yet) *long* term is quite questionable because their strategy of ever expanding behemoth monolithic dies is not sustainable because of the increasingly risky and finicky fabrication processes @ 7/10nm and below. Yields of huge GPUs must be scary on an unrefined 7nm hehe. (probably why no 7nm from NVIDIA yet)

But Intel is improving graphics and catching up slowly in GPUs just like AMD was catching up in CPUs 2 years ago. Intel was first to actually release an integrated CPU+GPU chiplet package (albeit with AMD Polaris GPU lol) ahead of AMD. This is a big warning shot to AMD: once Intel sort out their fab processes AMD will get another thwacking on all fronts. And Raja @ Intel is bound to help them improve their (presently very low) graphics quality. The performance/quality gap vs AMD should shrink significantly.

Its a nice rebalancing of power that should make AMD GPU and NVIDIA sweat a lil. AMD is peachy with trading garbage to mid tier GPU share vs ultra high margin server & high performance computing : at least a year or maybe even two of munching highly nutricious Intel lunch and dinner Looks like AMD is here to stay and compete.

tl;dr Ryzen 3rd gen is 15 %+ faster than Intel at half the power.

Per AMD/Lisa Su Keynote @ Computex:

Server:
* 50 EPYC cloud instances in production right now
* 1.5 exaflop supercomputer w/ advanced EPYC and Instinct
* EPYC in Microsoft Azure
* ROME 2x to 4x faster than Intel's Cascade Lake, launching Q3 2019

GPU:
* Radeon confirmed in Google Stadia
* NAVI: confirmed next gen Playstation w/ semi-custom navi and Zen 2, all new "RadeonDNA" architecture--not GCN, PCIexpress 4.0, new optimized compute unit design, new cache hierarchy, 1.25X faster than Vega, 1.5x more efficient than Vega...

Navi is Radeon RX5000 family: RX5700 10% greater than RTX 2070 on Strange Brigade demo, early version...July release...more at E3 June 10.

CPU:
* greater Microsoft partnership with AMD
* greater Asus partnership with AMD
* X570 mobos, 30 designs from Asus alone
* greater Acer partnership with AMD (Acer President Jerry Kao totally dissed Intel and Nvidia on stage)
* AM4, PCIe 4.0
* core w/ doubled floating point, doubled cache, InstructionsPerClock +15% uplift

Ryzen 7 3700X: 8 cores 16 threads, 3.6GHz base, 4.4GHz boost, 65 watts, 36MB cache, 15-18% gains over 2700x, beats Intel 9700K by 30% on Cinebench R20...$329
Ryzen 7 3800X: 8 cores 16 threads, 3.9 base, 4.5 boost, 105 watts, 36MB cache, 30% improvement over 2700X, matches Intel 9900K in PUBG demo...$399
9900K w/ 2080ti versus Ryzen 7 3800X w/ Navi RX 5700: 3dMArk bandwidth test, AMD system wins 25fps to 15 fps...

Ryzen 9 3900X: 12 cores 24 threads, 3.8GHz base 4.6GHz boost, 70MB cache, 105 watts, versus 9920X in blender--3900X 18% faster...$499

CPUs available July 7.

Doubled floating point translates to better than 15% improvement in most games, because games tend to be heavy on float.

And I tend to think Nvidia is the most vulnerable party in this (I assume CPUs are the more complex tech, and it's easier for AMD/Intel to design specialized processors than for Nvidia to ever bring a real competitive CPU to market).

They are; NV bet heavily on the currently imploding automated car market.
