Looking to get a better feel for that Yosemite National Park expedition this summer? Google Maps is looking to go beyond the regular ol' snapshot and offer an experience that feels more like an actual visit -- only you won't have to leave your sofa. The folks in Mountain View have added photo tours to over 15,000 sites around the globe from Italy to the aforementioned Half Dome in California. A search for your virtual destination of choice will indicate whether or not a tour is available for that particular locale. How does it work? The outfit uses user-contributed Picasa and Panaromio photos -- only those listed as public -- alongside some fancy computer techniques to provide a 3D tour. Along the way, Maps selects the best possible path through the highest quality images. At the bottom of each photo, contributor credit is given and Goog says when more shots get shared, these tours will improve over time. You'll need Google Maps with WebGL to get the sightseeing started, though. If you're looking for a quick preview, hit the video just past the break.Permalink | | Email this | Comments

Just a week before its Samsung Mobile Unpacked 2012 event where it will announce "the next galaxy smartphone," Samsung has officially announced what SoC will be inside. The answer is Exynos 4 Quad, which is no doubt the Exynos 4412 we've heard about before. Exynos 4 Quad is built on Samsung's 32nm HKMG process and consists of 4 ARM Cortex A9s running at up to 1.4 GHz. Samsung reports 20% lower power with Exynos 4 Quad over Exynos 4 Dual (4210), though it doesn't say at what clocks or workload. In the past, Samsung has claimed 40% lower power on 32nm HKMG compared to their 4xnm process.
Samsung also notes that Exynos 4 Quad has power gating on all four A9s, in addition to per core frequency and voltage scaling. This is an interesting move away from the one frequency plane shared across all cores architecture of Exynos 4210, and to the aSMP (asynchronous SMP) architecture similar to what Qualcomm has so far exclusively used. Samsung doesn't note what GPU blocks are inside Exynos 4 Quad, however Mali400MP4 at higher clocks seems likely. Samsung notes that the Exynos 4 Quad is both package (12 x 12 x 1.37 mm) and pin compatible with the 32nm Exynos 4 Dual (4212). Lastly, Samsung Semiconductor hasn't updated its A9 series catalog page, however I woud fully expect the new SoC to pop up before day's end.
Update: Samsung Semi has also uploaded a YouTube video demonstrating the Exynos 4 Quad and Exynos 5 Dual SoCs. Exynos 5 is shown powering a WQXGA display, and there are some clear shots of the Exynos 4 Quad running GLBenchmark Egypt.
