AMD's TDPs are calculated at all-core turbo. Intel's are only valid for base frequency.
Ah, so AMD doesn't have cheesy numbers- good to know.

Does Intel let you disable PSP? Meanwhile, AMD seemed to in the past[0]. 0: https://www.phoronix.com/scan.php?page=news_item&px=AMD-PSP-...
They don't have the choice on older chipsets that ME Cleaner has been reverse engineered to work with. Hence why its practicality. Neither respects user freedom, but the community has reverse engineered the ability to disable the backdoor of one company and not the other.

Do you work on a desktop machine? At home?
Whenever I'm having a remote day yes. Some projects can take literally hours to fully recompile. The more cores, the better. Will also be getting a Ryzen if the singlecore benchmarks show it's reasonable. Bunch of games I play at home tend to absolutely trash single core perf.

Nice. What build times are you seeing for clean builds of the rust toolchain itself? Curious to benchmark against my 2700x. I'd imagine near linear scaling with the core count. I think the 3900x might be a happy middle ground. I'm guessing we would probably see (with the increased IPC, core count, and core clock) like 70-80% increases over a 2700x in these kinds of multithreaded workloads. So probably slightly more t…
3900x looks fantastic on paper. In general, if the Ryzen stuff is sufficient for your needs, it's a better value. You pay a big premium for the Threadripper boards (and big case and big cooling solution). So in that sense, the 3900x is definitely in a sweet spot at the top of the Ryzen range. Tradeoffs: threadripper boards officially support ECC; Ryzen boards are hit or miss. TR boards tend to be priced around $300 w…

Potentially is a yield issue / segmentation issue. Releasing the top SKU as a 12 core instead of 16 core part gives AMD: 1.) Still the highest core count "Mainstream" part. I would expect Intel to fire back with a higher IPC / thread performance part rather then try and ramp core counts. Outside of productivity, content creation and server workloads I really don't see the need for anything past 6-8 cores right now. 2…
It's interesting though that Ryzen 9 is almost the highest clocked part of the bunch.
No 5GHz, I'm disappointed. Was considering switching to AMD, but Intel looks better. I'll wait for Threadripper announce, though, may be they'll release something powerful.
At close to 300 comments, I am surprised there is no mention of what I thought was the most important and surprise, 32 to 70MB L3 Cache. A lot of people focus on Core and Thread as well as IPC. We already knew what improvement IPC could do, we already knew what we could do 32 Thread. None of these are really new. But 64MB of L3 Cache? In a consumer CPU at a price that I would hardly call expensive ( I would even go o…
>we could have the whole languages VM living in Cache When dual-core processors came out someone said you could now have one core run your stuff and another run the anti-virus. That was widely joked about. This feels a little close to that. Having more CPU cache than we recently had RAM ending up being used for programming language overhead.
Looking back to the 8M total RAM I had on a Mac SE/30, running A/UX Unix and a MacOS GUI comfortably, the sloppiness of modern productions is a disgrace and an embarrassment.
What galls is not the wasteful extravagance. It's the failure of imagination that makes such meager, pitiable use of such extravagance. We make, of titanium airframes and turbojet engines, oxcarts.

This, people tend to forget what huge difference a few mb of cache can make. I'd prefer 1Mb more of cache over half a GHz of frequency.
(There's also the extra complexity around MiB vs MB for base 2 vs base 10 prefixes. In this case it would actually be MiB as RAM and cache is normally base 2 sized. But not everyone uses that, relying on convention from context instead.)

I don't mind 12 cores / 24 threads on my desktop. Makes compiling Mesa, Wine and Linux kernel a lot faster.
Cool, but we haven't seen compiling benchmarks yet. 12 cores might be bottlenecked by dual-channel memory.

No mention of it, but the pressure should still be on AMD to open source or allow firmware disable of their Platform "Security" Processor. I would really like to be more enthusiastic for my next build to use something like this, but all my computers are presently trustable in a way new platforms with proprietary coprocessors that haven't seen me_cleaner support cannot achieve. It really sucks to give Intel money - it…
Have you considered using the POWER9-based Raptor Blackbird uATX board for your next build? The firmware is open, and they advertise it as a feature: https://www.raptorcs.com/content/BK1B02/intro.html
