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.
