Fueled by its ultra-fast proprietary Hummingbird 1 GHz ARM Cortex A8 CPU (co-developed with Intrinsity), Samsung's Galaxy S and Galaxy S Pro Android smartphones offer beastly performance.  It will also be among the select set of Android smartphones to receive Android 2.2 Froyo, which should offer a further boost to performance.

That high performance, along with a cross-carrier launch on T-Mobile (branded the "Vibrant"), AT&T (branded the "Captivate"), and Sprint (branded the "Epic 4G") (with Verizon soon incoming, as well) has added up to a hit for Samsung.  The company just announced today that in the 45 days since July 15, it had sold one million units of its “Galaxy S” smartphones.

While that number falls short of Apple's record-setting annual iPhone launches (Apple worldwide moved 1.7 million iPhone 4 smartphones in 3 days), it's important to consider how saturated the Android market is.  Whereas there's only one Apple smartphone, there's a deluge of Android smartphones – this includes the HTC Hero (October 2009), Motorola Droid (November 2009), HTC Droid Incredible (April 2010), HTC EVO 4G (June 2010), and Motorola Droid X (July 2010), andMotorola Droid 2 (August 2010), to name but a few.  And that's part of why Android recently passed Apple (and Research in Motion, to boot) in U.S. sales.

The Galaxy S sales numbers are also impressive considering that Samsung is a relatively fresh face to the Android arena.  Traditionally, HTC and Motorola have been the top Android handset makers (as one might note by the above mentioned models).

Dale Sohn, president of Samsung Mobile states, "Bringing Galaxy S devices to multiple carriers has given Samsung Mobile the opportunity to reach millions of consumers.  I am proud of the instant success of the Galaxy S line up and I am very pleased to announce that because of the support of our carrier partners and loyal customers, we have shipped one million Galaxy S devices in the U.S. market. Samsung Mobile looks forward to sharing additional Galaxy S milestones in the future."

Aside from solid specs, Samsung credits a concerted advertising push with helping customers notice the new phone.  Samsung was a sponsor of X Games 16 and showed ads in movie theaters.  It also aired ad clips on ABC, CBS, FOX, NBC, ESPN and MTV promoting the phone.

It is very important to note that that Samsung managed all this before it even made it to America's largest carrier, Verizon.  When the Galaxy S variant "Fascinate" hits Verizon in September, expect more sales fireworks for the company.

All this bodes extremely well for Samsung's upcoming tablet dubbed the Galaxy Tab.  Using the same Hummingbird processor, 7-inch AMOLED touchscreen, and other high end components, the diminutive Tab looks to rival Apple's iPad in features and performance.  The device will be officially introduced at the IFA consumer electronics conference in Berlin on September 2 and is expected to launch shortly thereafter.
