Despite some Computex announcement real shipping of even 8 core models won't start sooner than mid July, most probably volume will be available only since September.

Some rumors tell that AMD can try to use higher prices to hold sales volume as they just do not have enough non defective dies. We must also see very strong push towards 4-6 core models, as now most of produced chips can be used in such mode only.

AMD during its 50th Anniversary luncheon that its 7nm products all carry a 50%, or higher, margin.

Nice capitalists. Friends of people.

According to our sources, the same who told us about the death of Global Foundries 20nm, the fully working Zen2 dies are about the 70% of the total production.

If we think that a fully working Intel XCC die (28 cores) has a rumored yield of 35%, this means that a 64C EPYC2 CPU has got a yield rate of 70% (8 x 8 dies). Almost the double of Intel yield rate!

If this guys want to compare such they need to compare around 32 nearby cores being all good at the same time and it is 0,7×0,7×0,7×0,7=0,24 . :-)

In reality having such small good working dies (I assume they include here even 2 and 4 cores working!) is very bad and can explain delays.

AMD's third-generation Ryzen series CPUs featuring the new Zen 2 architecture, and corresponding X570 chipsets are set to be unveiled at Computex 2019 at the end of May

Asus, MSI and Biostar have rolled out BIOS updates for their existing AMD B450, X370, and X470 motherboards to support the upcoming AMD Ryzen 3000-series, codenamed Matisse.

Some of industry sources tell that we can see biggest marketing hoax in recent history.

With AMD presenting only 8 core processors with hiked prices and around 20% speed improvement. With 12 and may be 12 core processors that will be left for October-November event.

Strong rumors are that TSMC is having serious issues with 7nm process costs.

AMD has confirmed to us that while the new Ryzen processors are compatible with motherboards designed for the first-gen chips, it will require new motherboards to fully support the PCIe 4.0 standard.

AMD representatives confirmed that 300- and 400-series AM4 motherboards can support PCIe 4.0. AMD will not lock the out feature, instead it will be up to motherboard vendors to validate and qualify the faster standard on its motherboards on a case-by-case basis.

Motherboard vendors that do support the feature will enable it through BIOS updates, but those updates will come at the discretion of the vendor.

Most older motherboards could support a PCIe 4.0 x16 connection to the first slot on the motherboard, but the remainder of the slots could revert to PCIe 3.0 signaling rates. That's because any trace routing on the motherboard that exceeds six inches requires newer redrivers and retimers that support PCIe 4.0's faster signaling rates. That means the PCIe slot nearest to the CPU will easily support PCIe 4.0, while the other slots, including M.2 ports, could run at PCIe 3.0. Support could be limited to slots based upon board, switch, and mux layouts.

One more reason to look for MB with M.2 slot on top of PCIe x16 one.

Also note that due to PCIe 4.0 new boards will be more expensive.

Ryzen 3000 (at least some models) and lot of MB will be presented at Computex 2019.

July 7 will be official sales start.

New data leak from closed press briefing of AMD considering upcoming CPUs.

AMD can decide to not introduce support of most or at least top CPUs for 3xx series chipsets based motherboards. As AMD marketing team found reason for this - to get more profits manufacturing used inappropriately small SPI flash (total savings are in $1 range), so AMD can declare that it is hard to add support for new CPUs. Press had been briefed to start slowly preparing people to calm people down, you can see this going gradual in coming months.

Ryzen 3000 series mobile chips are based on a 12nm Zen+ architecture and feature Radeon Vega graphics.

AMD is introducing four new Ryzen U-series chips for thin and light notebooks. These 15 watt processors are basically the company's answer to Intel's latest Core i3, Core i5, and Core i7 processors:

• Ryzen 3 3200U: 2-cores, 4-threads / 2.6 GHz base, 3.5 GHz boost CPU / 1.2 GHz Vega 3 graphics
• Ryzen 3 3300U: 4-cores, 4-threads / 2.1 GHz base, 3.5 GHz boost CPU / 1.2 GHz Vega 6 graphics
• Ryzen 5 3500U: 4-cores, 8-threads / 2.1 GHz base, 3.7 GHz boost CPU / 1.2 GHz Vega 8 graphics
• Ryzen 7 3700U: 4-cores, 8-threads / 2.3 GHz base, 4 GHz boost CPU / 1.4 GHz Vega 10 graphics

There's also a new Athlon 300U budget chip which rests below the Ryzen 3 3200U, with 2 CPU cores, 4 threads, a 2.4 GHz base speed, 3.3 GHz boost speed, and 1 GHz Vega 3 graphics.

Most recent leak, seems to be same as above.

Note that full leak or announcement will be in few days.

Very much looking forward to the announcement to learn how close these leaks were. If the 3850X/3800X BE are anywhere close to the leak I will be upgrading and passing on my 2700X to a friend. I purchased the X470 Asus C7H hoping it would be the most forward compatible board. We'll see what happens there.
