Inari Kon Kon Edition
- A leaked Biostar spec sheet confirms some earlier leaks of AMD's X570 chipset. (Tom's Hardware)
PCIe 4.0 everywhere; the new board has three M.2 slots all with 4 lanes of PCIe 4.0, for a theoretical 8GB/s of bandwidth, bidirectional, each. The two on the chipset are limited to a total of 8GB/s to the CPU though.
- Maybe we'd all be better off if the Bay Area quietly sank into the Arctic Ocean. (Salon)
I understand the geographical obstacles to this plan, but I kind of like the Pacific Ocean and wouldn't want to do that to the poor thing.
- 40% of Australians had their private information leaked in a single incident earlier this year. (ZDNet)
Though apparently we are not allowed to know what company or organisation was involved. That's private.

1*M.2 x 4 32Gb/s from CPU, PCIe Gen 4 x 4 & SATA
2*M.2 x 4 32Gb/s 2280 M.2 slot, PCIe Gen 4 x 4 & SATA from PCH
Actually, looking at the spec sheet more closely there are some inconsistencies (PCIe 3.0 M.2 on older boards but it says 32Gb/s there too).

The article gets more than that wrong (at least, compared to the picture shown of the spec sheet), too: the article says 1 x1 slot, but the sheet says 3; it claims there are "two 8+4-pin EPS connectors", which may not be wrong, but is misleading; pictures at VideoCardz show what looks like an 8- and a 4-pin, and "two 8+4" is not how I would've described it.
Also, anyone trying to fill that board out may be disappointed--there's something like 15 (or 19, depending on where the main M.2 is coming from) PCIe lanes all sharing the x4 PCH link, not counting the NIC, high-speed USB ports, etc. (I don't know if AMD works like Intel's HSIO lanes in that regard.)
 I don't know the proper term here--video cards, M.2 drives, things that plug into a PCIe bus, that is.

On the new motherboards the PCIe 4.0 uplink on the chipset will help a lot, at least in the short term. The fastest M.2 drives currently available do 3.5GB/s, so the chipset can run two at full speed. The uplink will eventually saturate, but 8GB/s of I/O - not including graphics - is a lot for a mainstream desktop.

So my new RTX 2070 is probably still going to run at the same speed in a putative x570 board, which is what I figured. Too bad--because running two 3.0 x16 video cards in 4.0 slots at 4.0 x8 would've been pretty cool. (I assume. I'm not hardcore enough of a gamer to bother with SLI/Crossfire.)
