Make no mistake – the Ryzen 5 and up CPUs in the 3000 series aren't just incrementally improved – they are legends in the making.

Good luck on the stock price @Heimdallr @tsk. I wonder what it will look like tomorrow.

Techspot/Hardware Unboxed managed to kill their 3900X with overclocking…

On an even more disappointing note, we somehow managed to end the life of our 3900X sample at this stage of the review. We don’t recall exactly what settings were applied, but we know we hadn’t manually adjusted voltages yet. We believe after testing the 4.3 GHz overclock with auto voltage, we increased the LLC to see what impact that had on temperatures and during our first CB20 pass the system crashed and reset, and never booted up again.

The CPU now gets stuck at code 07 after microcode. We tried running the chip on a different X570 board among other tests before sadly declaring it dead. AMD says no other reviews had managed to kill their 3900X so we’re just special or unlucky, your pick. AMD has sent us a replacement but in the meantime we were unable to test the 3900X on B450 boards, or include it in the IPC test with a few cores disabled in each chiplet.

From just the early benchmarks, it appears the 3700x, which is $329, is only like 4.5% slower then a near $500 9900k. And a 3900x basically performs like a Xeon with its multicore and does great with streaming.

You can 1t oc a 3700x to match a 9900k at least mine can but pbo and auto oc were not (currently) to my liking. Check out the longish written article.

Phoronix is reporting that newer distros like Manjaro, Fedora 31 and Ubuntu 19.04 will simply not boot Zen 2.

Yet oddly, 18.04.2 LTS boots just fine.

Should I pick up a 3900x or wait for 3950x reviews in september? My use case is light gaming, heavy handbrake usage.

the 3900x has all the cache the 3950x will have. The 3950x is formidable but on am4 I think there will be somewhat diminishing returns. $500 is a killer deal, too.

3950X is probably for full time streamers that want to use x264 on slow on the same system. (and video editors that need extra CPU)

3900X would probably be better for those at the casual level of streaming, or as a dedicated 2nd streaming system.

Any chance for a sudo lspci -vvv from somebody with a 5700 XT, I’m curious to see if it’s still plagued by lack of actual PCI reset support.

What about handbrake uhd encoding/compression. With a 2700x an entire movie takes 12hrs to encode.

More cores helps there as well if you need to transcode.

All I play is runescape and much older games. Mainly I transcode.

They want to ensure the AM4 socket actually backs it’s word about upgradability.

Here’s something that Looking Glass users might not like about Ryzen 3000.

Write bandwidth in AIDA64 is HALF of that of typical processors.
