If we're to believe several reports from the rumor mill, AMD's Leo platform, which will combine 890-series chipsets and six-core Thuban processors, will arrive in May. That's not too far off for online retailers to jump the gun, apparently. Fudzilla has spotted premature listings for an Asus M4A89GTD Pro/USB3 motherboard featuring an unannounced AMD 890GX chipset.
According to one particular listing at German e-tailer Magic Electronic Components, the motherboard also packs an SB850 south bridge, Radeon HD 4290 integrated graphics with DVI and HDMI out, two PCI Express Gen2 x16 slots (capable of running in a dual eight-lane config with two GPUs), PCIe Gen2 x4 and x1 slots, six 600MB/s Serial ATA ports, one eSATA port, and two USB 3.0 ports.
Pricing for the M4A89GTD Pro/USB3 looks to start at around €150 on the European mainland. We can usually get an estimate of pricing on the other side of the pond by adding 20% and swapping the currency symbol, which gives us $180—about as expensive as AMD's current fastest desktop processor. AMD may well charge more for six-core Thuban CPUs, though, which could justify pricier motherboards.
Fudzilla also spotted listings for an Asus M4A89GTD Pro, which lacks USB 3.0 connectivity and starts at around €134. That could mean U.S. pricing in the neighborhood of $160, which is already a tad more reasonable for a high-end Socket AM3 mobo.
