AnandTech have posted their roundup of AMD's Socket 754 with boards from Abit, Chaintech, Epox, Gigabyte, and MSI.
The second generation chipsets for Athlon 64 represent a genuine improvement in features, flexibility, and performance for AMD's flagship processors. As you saw in our chipset review, the nForce3-250 nVidia has added the features to bring their nF3 to the competitive edge of Athlon 64 chipsets. The HyperTransport speed, which was widely criticized on the 150 chipset, is now 800 or 1000 depending on the chipset version.
The on-chip Gigabit LAN and on-chip Firewall are also unique in A64 land and are truly useful features. nVidia also fixed the problems with their implementation of PCI/AGP lock on the 150, and we are finding a working PCI/AGP lock on every nForce3-250 motherboard that we test, just as nVidia promised.
VIA's update to their excellent K8T800 chipset was less dramatic on the surface as there are not many new features, but the improvements are just as dramatic under the hood. As detailed in our review of the K8T800 PRO chipset, VIA brings 1000 HyperTransport to the PRO chipset for all Athlon 64 Sockets: 940, 754, and 939. Perhaps the most significant improvement was the addition of a working PCI/AGP lock to the K8T800 PRO. While VIA had demonstrated very fast performance with the K8T800, particularly on Socket 940 Dual-Channel, many enthusiasts had stayed away from VIA due to the missing PCI/AGP lock. With the K8T800 PRO, the PCI/AGP lock, which some vendors call "asynchronous operation", is finally a VIA feature for Athlon 64.
Today, we are looking at 5 new motherboards featuring the new chipsets. Since nVidia was first out with their chipset revision, the majority of the motherboards feature nForce3-250. Abit is the only board sporting the VIA K8T800 PRO only because the VIA is a more recent announcement. We fully expect to see more boards in all Athlon 64 sockets using the PRO chipset in the future. With VIA pricing the PRO chipset the same as the earlier K8T800, there is no reason for manufacturers not to use the K8T800 PRO instead.
