Multiple AMD B450 motherboards Spotted at Computex
It'll be hard to find some real scoops at Computex this year. AMD will soon be releasing B450 chipset based motherboards that offer a bit more value. below the fold some photos of B450 motherboards on display.
The photos originate from the ASUS booth, who has at least four on display. The ROG B450 STRIX Gaming certainly seems to be nice, while mentioned the pending AMD B450 chipset details in our Ryzen gen2 review already really, here again, is an overview of details. You can click on the thumbnails below for more photos.
AMD is to launch a lower classed (budget) B450 chipset, only the X470 chipset is going to support SLI. That means the B450 does not (but does support Crossfire). The B450 will be a more budget aimed choice, which makes a lot of sense. Please notice that you will get your standard 20 PCIe 3.0 lanes pulled from the Ryzen processor. Ryzen all by itself has 24 PCI-Express lanes, 4 are being used to interface with the B450 or X470 chipset (which adds Gen 2.0 lanes as shown in the table). So depending on the chipset used it adds a number of gen 2.0 PCIe lanes through the chipset.
| X470 | X370 | B450 | B350 | A320 | X300 / B300 / A300 | Ryzen CPU | |
| PCIe 3.0 | 0 | 0 | 0 | 0 | 0 | 4 | 20 |
| PCIe 2.0 | 8 | 8 | 6 | 6 | 4 | 0 | 0 |
| USB 3.1 Gen 2 (10 Gbit/s) | 2 | 2 | 2 | 2 | 1 | 1 | 0 |
| USB 3.0 | 6 | 6 | 2 | 2 | 2 | 2 | 4 |
| USB 2.0 | 6 | 6 | 6 | 6 | 6 | 6 | 0 |
| SATA 6 Gbit / s | 4 | 4 | 2 | 2 | 2 | 2 | 2 |
| SATA or NVME Raid | 0/1/10 | 0/1/10 | 0/1/10 | 0/1/10 | 0/1/10 | 0/1 | - |
| Overclocking | Yes | Yes | Yes | Yes | - | X300 Yes | - |
| CrossFire / SLI | Yes / Yes | Yes / Yes | Yes / - | Yes / - | - | - | - |
Each chipset will add select numbers of USB ports, the Ryzen processor also offers four native USB 3.1 ports. There is support for RAID 0/1/10 configurations both SATA and now NVME as well as overclocking support on the X470 and B450 chipset. B450 will also support enhanced XFR2. Obviously, the motherboard partners could add 3rd party chips to increase USB 3.0 and so on.

Plan was to multiplex more PCIE lanes using multiplexor chips, but that meant they'd have to design around it, so they had to make sure whatever chip they chose for their design had ample supply because they coudn't drop in an "alternative". There weren't enough from any supplier.
tl;dr: They cancelled it due to the fact they couldn't source a reliable supply of PCIE multiplexor chips
So where is this rumored Z490 chipset that was supposed to release this month?

Ah ok, so there will in fact be no z490 anytime soon. I was actually waiting on purchasing a new board with the latest chipset but if it’s vapor ware I suppose I’ll just go ahead and narrow my search down to the latest currently available. Thanks for the info
