As we always think that more cores will mean far better rendering, this review will give us hard evidence whether or not that is real.
First of all, let’s get the specifications laid out. The 6800K is a 6-core CPU with 12 threads and is able to handle 28 PCI lanes. The 6700K is a Quad-Core CPU with 8 threads. It can take care of 16 PCI lanes and is smaller physically. The base & boost clock of the 6800K is 3.4GHz & 3.8GHz respectively but can only overclock to 4.2GHz @ 1.4 volts. For the 6700K, base is 4GHz and boost is 4.2 GHz with an OC up to 4.5GHz at 1.24 volts.
On to the real battle. In video compressions, openCL and heavy multitasking, the 6800K beats the by 6% to 28%. However, with Adobe Premiere Pro when encoding media, it gets a measly improvement of 7-8%. This changes with Adobe After Effects. The time to camera track/ warp stabilize is drastically lower for the 6700K making it better in this area by 15%. In CPU intensive games, the 6800K gives out slightly more frames of about 5 to 8.
Overall, this shows that the 6700K is still very efficient for video editing and games. If people go with the 6800K, the benefits are rather small while having to pay more for it and the motherboard.
