Apparently, someone holding on to a Sony C6603 unit ran the benchmark on it just to see what the handset was capable of. The listing confirms that the smartphone they tested had a screen with 1920 by 1080 pixels of resolution, an Adreno 320 GPU, a 1.5GHz CPU and ran Android 4.1 Jelly Bean.
LG Optimus G, the LG Nexus 4, and the Asus Padfone 2. In other words, performance is highly unlikely to be an issue with the Sony C6603 Yuga. And by the way, that moniker is probably just a codename.
The Sony C6603 Yuga is presumed to be scheduled for an early 2013 announcement, alongside its rumored sibling, the Sony C650x Odin. The former will probably look like this.
Thanks for sending this in!
UPDATE: It is rumored that the Sony C6603 Yuga will have a glass back, a 2,400mAh battery, and IP57 certification, meaning that it might be resistant to dust and water damage. Unfortunately, we have no way of confirming these details yet, so take what you just read with a pinch of salt.
