All of them as it's a chipset controller limitation/bottleneck from what we could establish. Hypertransport appears to be getting a bit long in the tooth now and they seriously need to stop hanging onto boards that are half a decade old and give the whole lot an overhaul.
Hypertransport is controlled by the MCH in the CPU, not the chipset. Total bandwidth is not that much lower of a comparably priced Intel CPU and not at all is the bottleneck in the system if needed for a common DAW, usually it is the CPU and HDD.
besides this, Intels Quickpath technology is almost a direct copy of the HT bus from AMD, so you could say Intel was very slow to implement such an old method.
Chipsets for AMD systems mostly control PCI-e bandwidth, USB and is the HDD controller, none of this in the chipset is slower or has less bandwidth then Intels current flagship chipset for desktop the X58, actually AMD chipset already natively support USB 3.0 while you need to add another controler chip on an Intel system for USB 3.0 support, making it more expensive then needed.
Also nobody ever looked at what Intels CPU controlled PCI-e/MCH will have as effect in the future, when these hi-bandwidth protocols are fullly utilised in the near future. I don't expect we will still be able to utilise the full PCI-e 2.0 bandwidth and the 8,5GB/s memory bandwidth together pumped through the CPU.
and this coming from an Intel user ...
edit: Server/workstation; totally different ballgame?
maybe not. Have a look at AMD G34 chipset boards, for the price of a system based on the the topmodel Corei7 you can build a 24core (yes indeed: 24 cores) AMD system w. Also AMD server/WS boards widely support desktop operating systems in comparison to the Intel Xeon chipsets do not.
yes, Intel has the fastest chip/highest memory bandwidth, but only if you pay dearly for it. If like most of us you are on a certain budget you'd be plain stupid to discard AMD as a possible option. Even if someone representing a PC reseller recommends otherwise.
Edit2: Sorry I made a mistake, Quad CPU AMD boards are still a little expensive. For the price of Intels fastest desktop CPU + MB you can only get a 16 core AMD system and still save a few hundred euro's.
Anyone already benched a dual 8-core Opteron vs the i7 980?
