An unnamed, undressed dual-GPU prototype of AMD's latest in southern-island graphics cards surfaced over the weekend. Flaunting twin Bart chips with 1,120 stream processors a pop, this card totals up at 2,240, with each GPU packing its own memory for a total of 2GB of GDDR5. Although PowerColor is staying tight lipped on specs and official name until Computex in June, two DVI ports, double mini DisplayPorts, and one HDMI-out paint obvious similarities to the existing Radeon HD 6870. One last notable difference? The unknown soldier is powered by two eight-pin PCIe connectors, as opposed to the HD 6870's six-pin variant. We're probably looking at the latest in the Radeon HD 6800 series, we'll know for sure in about a month. SemiAccurate

If you're reading this, we're going to go ahead and assume you've got a computer endowed with its own wireless radio, but that doesn't mean it's powerful enough to handle your non-stop streaming these days. For folks craving more oomph, TrendNet has just announced the first USB adapter that promises to boost your throughput to speeds as high as 450 Mbps (thanks to MIMO technology) -- a mighty boost over the 54Mbps or 150Mbps rates you might be used to. As a dual-band adapter, it'll connect to either 2.4GHz or 5GHz networks and -- bonus -- its design is relatively discreet, too. Feel the need for speed? It's on sale now for $80. MacNews TrendNet
