AutoCAD renderings of the Sony Xperia Z3 and its little sister, the Z3 Compact, have leaked online this morning, revealing the dimensions and some specs of the two upcoming devices expected to be revealed at IFA in Berlin next month.

The first rendering is of the main flagship, the Z3. The dimensions show the device coming in at 146.46 x 72.09 x 7.3 mm, which is smaller than the Z2 in every way. The Z2 measures in at 146.8 x 73.3 x 8.2 mm and weighs 163g, so it seems likely that the Z3 will be lighter than the Z2.

The second rendering is of the Z3 Compact, Sony’s smaller variant of the near-phablet sized Z2/3. The Z3 Compact is said to measure in at 127 x 64.9mm. For some reason, the photos don’t include the thickness of the Z3 Compact, so for now we’ll just have to guess. Strangely enough, the size of the Z3 Compact is the exact size of the last Compact phone Sony made, the Z1 Compact.Z3 Compact Renderings

The renderings don’t include any specs for either device, but rumor has it that the Z3 will feature a 5.15″ 1080P display, a Snapdragon 801 clocked at 2.4 GHz with an Adreno 330, 20.4MP rear shooter, and 16GB of internal storage. The Z3 Compact on the other hand should have similar specs, but with a screen size more in the 4.3″ range.

Both devices are expected to be revealed on September 3rd at IFA, hosted in Berlin.
