Panasonic Lumix DMC-GX7 Expert Review
I took a look at the pics as well as when they did the review of the GH3. Looks like GH3 still better high iso jpg shots. I did a crop of both it and gx7 - could not do raw since none of my converters can do the gx7 - but it appears the hoopla about GX7 being best sensor is not backed up by photos.
Here's two shots at iso 3200 jpg cropped. links below for actually download.

Panasonic Lumix DMC-GH3 Review
To me, the GX7 file looks less noisy than the GH3, especially in the gray and colored boxes. The dark background of the GX7 image appears at first glance to be noisier, then I notice the background of the GH3 image is bluish tinged, perhaps some WB shift at high-ISO?
Not sure. I can see more chroma noise in the grey squares in the GH3 sample ...
Looks a little less noisy and a little less detail to my eyes. More noise reduction maybe?
I think comparing OOC Jpegs at 100% crop is a bit pointless (for sharpness comparison anyway) since every camera has its own baseline NR even when its turned off by the user. We need RAW data passed through the same converter.
It could just be the case that the GX7 has a great sensor crippled by an immature or overzealous JPEG engine
oh the wb is a mess but that is irrelevant - can be fixed in post - the gh3 looks clearer - gx7 just using more NR imo
I think the GX7 image has less noise, but as others have said these files don't tell us anything, since 1), the GX7 files are still pre-production and b) we don't have any idea how much NR is being applied.
The internet has opened up the flood gates of clueless testers running meaningless tests which are then cited by unknowledgeable users to justify whatever they want to be true.

+1 . We need production-final RAW file output before we can start to make any meaningful judgements.
DPreview just posted their new comparison tool that shows some interesting results.
Panasonic GX7 First Impressions Review: page 2: Digital Photography Review
GX7 may have a little more noise, but seems to preserve detail a bit better.
Woah, this new tool is a lot better. For all intents and purposes, I'd say the performance is equal, with the tiniest advantage going to the GX7. At 3200, the E-P5 seems to have the tiniest negligible advantage, while at 6400 and above, the Panasonic emerges slightly victorious. More importantly, however, the Panasonic seems to have better color at these high isos, and less shadow noise even if detail resolution remains very similar. Now I'm just curious as to how it retains dynamic range with high sensitivity.
Interestingly, the NEX-6 looks strictly on par with the M4/3 cameras here, when before it seemed to have a slight, but clear half stop advantage. The 5D Mark III seems only be 1-1.5 stops ahead, instead of two. Exif info shows equal exposure settings, so I wonder if this wasn't equal before. But then again, I didn't account completely for the increased megapixels.
Still, for me the most surprising thing about the GX7 is how much I've been liking the jpegs that come out of it during daytime low iso shooting. Colors look way more natural than what I'm used to from Panasonic. The main improvement they've played up with this new sensor is increased/more accurate color saturation, and I don't doubt them. The colors so far seem about as good as or better than what I've seen from Fuji's jpegs, which is seriously saying something. Doing a quick search of "GX7" on flickr, I haven't seen a single photo shot in daylight where I can say the colors are bad.
I have also found a [ame="https://www.youtube.com/watch?v=BuepjjsWs0w"]video[/ame] for this product.
