A WiFi-only version of the Samsung Galaxy Tab recently hit the market, and while it looks virtually identical to the 3G model which was launched last year, it turns out there are a few key differences under the hood. Samsung isn’t really publicizing these changes, but users have discovered at least three things (aside from the lack of 3G) which set the WiFi tablet apart from the original:
- Instead of a 1 GHz Samsung Hummingbird processor, the tablet uses a different 1 GHz ARM Cortex A chip, offering similar overall performance.
- Instead of PowerVR SGX540 graphics, the new model has PowerVR SGX530 graphics offering significantly less graphics power.
- The new model has Bluetooth 2.1 instead of Bluetooth 3.0.
While users report that the processor, which appears to be a Texas Instruments OMAP3 chip, doesn’t seem much different from the processor used in the 3G model, the PowerVR SGX530 graphics is another story.
Users are reporting that while the 3G model of the tablet can handle 1080p HD video playback, the Samsung Galaxy Tab WiFi tops out at 720p HD video.
The rest of the specs for the new WiFi model match the 3G model. Both tablets feature 7 inch, 600 x 1024 pixel capacitive touchscreen displays, 16GB of storage, 3MP cameras, and Google Android 2.2.
