So, the son of G1 is now out and open for retail consumption, and it’s certainly an interesting device. This is one of the first high end GSM HTC Android devices in a while, so it’s been understandably hyped. The keyboard is another unique factor - this is HTC’s first Android device with a physical keyboard since the original G1, and the G2, along with the Samsung Epic 4G and Droid 2, is currently the one of the few high end Android devices with a physical keyboard.

The G2 comes with a Qualcomm MSM7230 SoC, an 800 MHz part based on the 2nd generation Snapdragon core. It’s now on a 45-nm manufacturing process (the original Snapdragon QSD8x50 parts are 65nm) and has an updated Adreno 205 GPU. Beyond the die-shrink, the CPU seems to be relatively unchanged compared to the first gen-Snapdragon, just running at an 800 MHz frequency. The lower clock speed is probably to keep power consumption and yield in check for Qualcomm's first 45nm SoC. The Adreno 205, on the other hand, seems to be a pretty big improvement over the previous generation Adreno 200. The 205 adds hardware acceleration for Flash, SVG vector graphics hardware acceleration, and significantly improves shader performance over the Adreno 200. Performance is expected to be far more competitive to the PowerVR SGX 530 and 540 than the Adreno 200 ever was. So even though it doesn’t break the magical 1GHz mark, the MSM7230 is still a very potent SoC, especially in a device that forgoes the burden of a custom UI layer on top of Android.

The MSM7230 in the G2 has support for 3GPP Release 7, which includes HSPA+ and Evolved EDGE support. The G2 supports HSDPA class 10 for a maximum theoretical downstream rate of 14.4 megabits/s, and HSUPA class 6 for a maximum theoretical upstream rate of 5.76 megabits/s. Qualcomm's MSM7x30 series SoC comes in another flavor - the MSM7630 -  which packs HSPA+ support alongside CDMA voice and data.   

Rounding out the other specs, we’ve got 512MB RAM (also part of the SoC), 4GB internal NAND with an 8GB microSD card preinstalled (more on this later), a 3.7” Super-LCD TFT display with an 800x480 resolution, a 5 megapixel camera with autofocus and an LED flash, 720p video recording at 30fps, and a removeable 4.81 Wh (1300 mAh) battery. Oh, and one of the weirdest hinges out there right now.

    "the first HTC GSM Android device (since the Nexus One)"

    Actually the HTC Aria was released in June on AT&T.

    I think we are to assume that such statements are limited to tier 1 phones. In if it doesn't cost $200, it doesn't count.

    Good catch though, I'm sure Gowri will respond with a proper answer soon.

    Good catch, I completely forgot about the Aria. Nothing against it, it's a nice little phone, but it's not a real high end Android device (which is what I was thinking about when I wrote that). ImSpartacus was right, I was basically just looking at the so-called "superphones". Reply

    Then there's also the HTC Desire... Reply

    "As the first GSM Android device with a keyboard (since the G1)"
    I Believe the Tmobile MyTouch Slide fits that description and has been out for months now :)

    You could replace the phrase, "the first device since..." with, "since ... there haven't been too many other (if any) devices that..." and fix all your mistakes in one swoop :) Reply

    When the Engadgets of the world are all posting their G2 REviews, AT is posting its PREview.

    I <3 Anandtech's thoroughness.

    Actually, considering that the mass-produced units may have a bunch of the issues taken care of there is nothing wrong about it.

    Not forgetting that an AT "Preview" usually has about as much useful data in as an Average "Review" ... It is not hard to churn out 20 pages of spin.

    To me it seems a limited amount of AT man-hours along with probable-to-be-corrected-soon type of device is the reason.

    I think he was saying that AT takes the time to do the reviews right? Reply
