The Microsoft Surface Pro 3 tablet has officially launched with Intel i3 and i7 processors under the hood, available now in the U.S. and Canada.

Microsoft launched its new Surface Pro 3 tablet back in May and said at the time that it will offer the slate in three versions with different processors: Intel Core i3, Core i5, or Core i7. The Core i5 models were the first to hit retail and were the only readily available options up until now, but the Core i3 and Core i7-powered variants have finally made their debut as well.

The Microsoft Surface Pro 3 Core i3 and Core i7 models are now available for purchase in the U.S. and Canada. As expected, the i3 version is the base model with the lowest price tag, coming in at $799 with 64GB of internal storage capacity on board. The highest-end Intel Core i7 model, meanwhile, comes with 256GB of flash storage for $1,529, or 512GB of storage for a hefty $1,949.

"Surface Pro 3 is the first generation of Surface Pro for which we've offered this range of configurations," reckons Microsoft. "We did this so that our customers could decide which Surface Pro 3 is right for them. This is the tablet that can replace your laptop, and we know that laptops and tablets are used differently by different people. The new range of products accommodates this with a different processor, memory and storage of options and price points."

"Every Surface Pro 3 offers the iconic features that make it an amazingly productive device regardless of the configuration - each has a beautiful 12" ClearType HD display, each has a multi-position kickstand and Surface Pro Type Cover (sold separately) that give you the flexibility to work well on your lap or really anywhere, each comes with Windows 8.1 so you can run apps from the Windows Store as well as desktop software, and every Surface Pro 3 has the Pen with its brilliant OneNote integration that makes note-taking and sketching so easy. Every Surface Pro 3 is also thin, light, extremely well built, and a pleasure to use as a laptop or a tablet."

The new Surface Pro 3 models with fourth-generation Intel Core i3 and Core i7 are now available for purchase in the U.S. and Canada through Microsoft Stores, Best Buy, as well as other Surface retailers and authorized device resellers.
