    Waiting for the B450 motherboards to come out, don't want to mess around obtaining a boot kit to flash a b350 when I order my R5 2600.

    Re: AMD - Zen chitchat

    TIL: Intel have multiplied the 8700, for some reason. We already know about the 8700k, and the plain 8700 (the 65W desktop chip), but intel have spawned two others - the 8700T, a 35W desktop chip, and the 8700B, a 65W mobile chip. The B is literally just a BGA 8700 (gunning for the laptops squeezing a 2700 inside them?), and I think the T is just to show off. Would make a mean passive system though, that's lump-of-metal-without-heatpipes cooling solution territory

    Intel have been doing low power T-variants desktop chips for almost as long as there have been core i processors; looks like the first i7 to get the treatment was Ivy Bridge with the 45W i7 3770T. My guess is that they primarily target OEM SFF workstations, but they do appear at retail too and would make a reasonable choice for most SFF systems....

    I'm pretty sure AMD could respond if they wanted to (based on the specs for EPYC they could push out a 2700E at ~ 2.2GHz base in a 35W envelope) but it's a bit of a niche market. Plus I strongly suspect that the standard 2700 has configurable TDP down to around 45W with a supporting BIOS, and I don't know of many completely passive workstations anyway...

    Some 45W TDP E series Ryzen CPUs have been leaked as well as some new lower end 4C/8T ones:

    Edit!!

    35W TDP 2C/4T Ryzen APUs were also leaked a few days ago:

    AFAICT this is a rumour that someone tried to start back in 2014, and was bumped via Reddit during Computex this year. There's no credible sourcing for it, and given how easy it'd be for someone to check, I intend to take the suggestion with one of these:

Not that I'm saying it's can't be true, mind; I'm just not going to assume it is true based on one dubious source.

    Asus B350 Plus M-ATX mobo has to ps/2 ports. Does that mean that there is a better chance one can get Windows 7 to install on it if you connect mouse and keyboard to that.

    It is an unsupported platform by policy not by lack of PS2 ports. The B350M-plus gaming I used at work seems to have Win7 drivers available, I would check the driver download page for the motherboard you are interested in. I think at this point whatever you do with Win7 is a bit of a punt though.

    This. You'll almost certainly get Windows 7 to install, particularly if you're just sticking it onto a SATA hard drive or SSD, regardless of the presence of PS2 ports. How much will work under Windows 7 will depend, as DwU says, on whether the motherboard manufacturer has chosen to produce drivers. In any case, you've got no guarantee of any future updates, security or otherwise, as you'll be running an unsupported OS for the platform from both MS's and AMD's point of view.

    What's the use case that requires Windows 7?

    Re: AMD - Zen chitchat

    https://www.theinformation.com/artic...s-door-for-amd

    Advanced Micro Devices’ battle with chip giant Intel has often seemed like a gnat fighting an elephant, with AMD struggling in recent years to gain even a tenth of the market for the chips that power PCs and data center servers. Forrest Norrod, a senior executive who joined AMD four years ago, says the company suffered from “little brother syndrome” where it tried and failed to compete with Intel on lots of different chips.

    Now, though, AMD may have a shot at coming out with a faster, more powerful chip than Intel for the first time. Intel in April said it was delaying the release of a more advanced chip manufacturing process until sometime in 2019. AMD has its own new, advanced chip, which it will now be able to release earlier than Intel, potentially giving it an edge in the market for high-performance chips for PCs and data center computers.

    It's a market opportunity worth around $50 billion. That’s what Intel makes from selling chips or PCs and data center servers, and it dominates both markets. The data center market is particularly important because of the growth of new technologies like artificial intelligence–related applications, much of which is handled in the cloud. Companies that buy chips for data centers or PCs could gravitate to AMD chips as a result of Intel’s delay.

    “I think we have a year lead now,” said Mr. Norrod. AMD now has “an unexpected [manufacturing] advantage for the first time ever,” he added.

    AMD wasn’t in a position to take advantage of Intel’s product delays until recently. CEO Lisa Su, who started in 2014 and hired Mr. Norrod shortly afterwards, has focused on a fewer number of chips where it had more of an edge, such as high-performance processors at lower prices than Intel. That was a reversal of AMD’s past “little brother” strategy of competing more broadly.

    Mr. Norrod freely admits that when he joined AMD, it was “in really bad shape.” Intel was sucking up all its traditional business of selling processing chips for PCs and data centers. Nvidia, meanwhile, was establishing a lead in selling graphics processors into the nascent artificial intelligence market.

    There are signs of progress. AMD’s revenue was up 23% last year and it turned a small profit of $204 million, after losing money the previous two years. AMD’s market share in the central processors for PCs and data centers has risen to 8.6% from 7.9% between the fourth quarter of last year and the first quarter of this year, according to Mercury Research.

    Still, any fight between AMD and Intel is a David-and-Goliath struggle. Intel is a giant, with $64 billion in revenue, roughly $10 billion in net income and a market capitalization of $260 billion. AMD, on the other hand, has revenue of a little above $5 billion, a market capitalization of $14.4 billion and a history of struggling to even turn a profit.

    Intel long had a manufacturing advantage because it makes its own chips. AMD contracts its manufacturing out to companies like TSMC and GlobalFoundries, which originally spun out of AMD in 2009.

    But Intel has been having problems making chips at a 10 nanometer density—a measure of how closely it packs transistors together on a chip, which has traditionally been important for continuing to improve chip performance. As a result, Intel continues to make chips based on its older 14 nanometer-density. AMD, in contrast, announced this week it is testing the first version of a graphics processing chip using 7-nanometer density technology, being made by TSMC, which is comparable to what Intel is trying to make.

    Intel didn’t respond to a request for comment. Last month, at Intel's annual shareholder meeting, CEO Brian Krzanich said there was "absolutely not" a competitive threat posed by its manufacturing difficulties. “We think we have one of the best roadmaps that Intel’s had in its history moving forward,” he said.

    The manufacturing glitch is the latest in a series of challenges for Intel. It missed the mobile market and has struggled to diversify into areas like cybersecurity and wearables such as smart glasses. But it dominates the market for PC and data center server chips.

    Graphics Counterattack

    Intel is now mounting a counterattack on graphic chips, where it has historically been weak. Intel recently nabbed the chief of AMD’s graphic chip unit, Raja Koduri, to head a new high-end graphics chip unit. Intel has tried and failed to build graphics chips several times in the past. But graphics processing units, also called GPUs, have become a more important market in recent years. Nvidia, for instance, which specializes in graphics chips, and is selling them in new areas like artificial intelligence and cryptocurrencies.

    Intel also recently hired well-regarded processor architect Jim Keller, who led the design of the current processing chips of AMD before he left in late 2015. That hire was a sign that “Intel is focusing more on chip architecture,” said Bernstein Research analyst Stacy Rasgon. “When you can’t have [manufacturing] advantage, architecture becomes more important.”

    Intel apparently enticed Mr. Koduri by giving him oversight of a huge new organization, the Core and Visual Computing Group, and making him chief architect at Intel. Mr. Koduri had clashed with AMD management over the future direction of the graphics chip unit, which he wanted to spin off and make independent, said two people familiar with the situation. (The clashes were previously reported by PC hardware website HardOCP.

    Mr. Norrod played down the significance of the hiring. “Raja is a brilliant guy, a brilliant architect, a brilliant marketer, but he lives in the future,” he said. “He’s running a massive organization, and based on my perceptions of Raja and my experience working with him, that doesn’t play to his strengths. We’ll see what happens.”

    He also claimed that AMD’s graphic chip business is doing a little better since Mr. Koduri’s departure. Under Mr. Koduri, AMD changed product plans for new graphic chips several times. “We had some wastage on the GPU roadmap where he changed his mind,” he said. “I think that since we’ve really locked that down, we’re making a little bit more rapid progress.”

    Mr. Koduri didn’t respond to a request for comment.

    Because of the time it takes to build a new chip, Mr. Norrod doesn’t expect Messrs. Koduri and Keller to have any impact at Intel for at least another three years. He argues that gives AMD, for now, an historical advantage it’s never had before.
