A profile of the Samsung Galaxy S3 for Verizon reveals the carrier is getting a dual-core Qualcomm Snapdragon processor, rather than Samsung's own quad-core Exynos CPU. This news comes a day before Samsung's likely reveal of the device in London, on May 3.

According to Pocketnow, a recent user agent profile (UAF) suggests that the Verizon-headed Galaxy S3 is going to be powered by Qualcomm MSM8960 S4 Snapdragon processor and not Samsung's Exynos 4 Quad chip.

Though there's no specific mention of the S3 name, the model number SCH-I535 appears. The phone also runs Android 4.0 Ice Cream Sandwich with a 1280x720 resolution. The SCH naming also follows other Verizon Samsung devices, such as the Samsung Galaxy Nexus - SCH-I515 - and the Galaxy S Fascinate, the SCH-I500. On April 26, BGR reported Verizon was planning to carry the phone.

On the same day, Samsung officials claimed there would be three versions of the phone when speaking to The Korea Times. While the quad-core Exynos version will be made available to global market, a Snapdragon-based model will head for the U.S. HTC followed a similar route when bringing the One X to the U.S., replacing the quad-core Tegra 3 with Snapdragon processor to support AT&T's LTE.

A possible reason for a different U.S. device could be because Exynos quad-core chips are not compatible with the modems necessary for 4G networks in the U.S. However, this information hasn't been officially confirmed so there's every chance it could be false.

Samsung's quad-core Exynos chip runs at 1.4GHz per core and is based on the ARM Cortex 9. Samsung claimed it has two times the processing capability over the Exynos 4 dual-core, which uses 20 percent less power. The quad-core chip is also claimed to be suited for 3D games and video editing, along with 1080p video playback at 30 frames per second.

Samsung's Galaxy S3 has dominated the smartphone rumor mill in recent days: photos of a Galaxy Note-esque device that supported five-icons rows surfaced, a photo of the device showing an eight megapixel camera and Samsung's own teasing of an Exynos processor. With only a day to go before the expected May 3 debut, it's only a matter of time before everything becomes clear.
