So for a similar launch price you get >2x the performance, almost identical pcie bandwidth (4x28) and faster memory (less of it though). Seems pretty great to me?

8x DDR4-2666 -> 2x DDR5-5600 is half the memory throughput too. That was the first thing that made my head scratch; having much bigger cores & still lots of PCIe throughput, but way less memory bandwidth. That said, 8x DDR4-2666 also scaled up to 64c chips in Naples, this isn't unreasonable.

One thing to consider is the growth of cache. If you have better L3 hitrate (which you should given the doubling of L3 cache and 10x growth of L2 cache), you ease up the memory pressure a bit.

The Ryzen 9 5950x launched just under two years ago at $800. This is an improvement on those prices. The improvements in IPC over the original Zen core of the EPYC 7281 are quite substantial, and AMD is in a much better position than it was those five long years ago.

One downside is that the TDP is almost doubled (170/~230 W vs 105/140 W for default/PPT) which may be a dealbreaker - certainly for my SFF system where I'm not sure I can cope with another 100W. These are limited by the socket really (AM4/AM5), but still it's nice to have that many threads in such a low power budget. I'm more curious to see what the 32-thread competition turns out to be in the same TDP bracket.

See the part of the article starting at “We’ll first start with iso (like-for-like) comparisons between Ryzen generations, with iso-power.” That shows “up to +37%” at 105W.

So the big questions on this and Intel next-gen process releases:

1) so it is just the process that gives the Apple ARM laptops their superior battery life?

2) if so (I doubt it will be), when will there be as good a performing laptop example in x86?

3) if not (as I suspect)... what is the actual response to the M1 gauntlet by Intel/AMD? THeir own ARM chips?

If Wintel tries to go ARM, it is the last opportunity for Linux desktop inroads, or perhaps an opportunity for Windows to go full-core Linux with windows as the UI.

At this point after 25 years of linux desktop being subpar, I welcome a major player, even goddamn Microsoft, and yes I remember every horrible thing Microsoft has done in the last 40 years of my life, to take the bull by the horns.

Microsoft is the lesser of two evils. Apple will dangerously close the freedom of the software on their machines to push everything to app stores. Microsoft, to their credit, I think the first time I have ever praised them, is more open in their platform approach historically.

But... nah, it won't happen.

Die Area of only 3.84mm2 for Core + L2. This is a similar to Apple A14/A15. On TSMC N5 although they are likely different variant, optimising for clockspeed rather than Low Power. 13% increase in IPC, and additional clock speed increase as well from N5. The server variant Zen4C with 128 Core per socket should compete fairly well with Ampere ARM variant. I just hope AMD is a little more ambitious than they were and bo…

So like 5 years ago when the ryzen came out and made 8 cores accessible to the masses, you didn’t get a little tingle of excitement at the sudden competition?

Any word on official ECC support? (And I don’t just mean it can use the RAM, I mean for it to gain the actual benefits of ECC)

The most official thing I've found about it so far is a line at https://www.amd.com/en/product/12166 (source: https://www.amd.com/en/products/cpu/amd-ryzen-5-7600x) which says "ECC Support: Yes (Requires mobo support)"

Microsoft tried everything they could imagine to try and kill off Win32 and force everything and everyone onto Microsoft Store with locked down MetroModernUIImmersiveUWP software.

They all failed because the entire reason for Windows's existence is users can install and use practically anything anywhere anytime.

So no, Microsoft is not open. They do not want Win32 and its open nature. Microsoft is salivating at the kind of walled garden Google and Apple managed to erect, and would try for it again the next chance they get.

Love that these include a basic igpu. Makes them much more viable for home server and low end desktops(when eventually discounted).

I personally suspect that the true reason for that integrated GPU is the USB4 support. Always having that integrated GPU allows for full USB4 directly on the motherboard without needing hacks like looping a DisplayPort cable from the discrete GPU to the motherboard. And I believe it's possible to render in one GPU but present the output through another GPU, so you could in theory even use a discrete GPU for rendering while the output is going through the USB4 socket on the motherboard, without any extra cables between the graphics card and the motherboard.

I wonder if they ended up adding so many MLCCs to the top of the substrate to try to hit the higher frequency targets (especially with higher multicore power draw), or if they were required due to the different process or uArch changes.

Probably the former, which isn't as interesting, but it is visually striking either way.

Too bad AMD doesn't seem to be doing well with USB4 so far. And with a "basic" motherboard now priced at $125 I'd rather skip it anyway.
