MSI introduces refreshed AMD Radeon RX 6800 / 6900 GAMING TRIO cards with higher clocks and redesigned backplates
The refreshed models include Z TRIO and TRIO PLUS variants for the AMD Radeon RX 6800, 6800 XT and 6900 XT SKUs. The Z TRIO lineup has slightly higher clocks for the XT SKUs, while the TRIO PLUS one mostly features the same clocks with one exception. Both lineups get redesigned backplates similar to the ones on the X TRIO 6900 XT.
