Huh? What the heck is going on here? The CPU results of our CineBench test follow the pattern we've seen in all of our previous tests, although the stock 875K is lagging behind somewhat.
However the OpenGL test is nearly entirely incomprehensible. We all know that clock speed pumping data to the GPU is more important than the amount of cores doing the data pushing. So the 655K dual-core performing so well isn't a massive surprise. But the relatively poor performance of the 870 and 930, coupled to the incredible performance of the 875K, does make us scratch our head somewhat.
Giving further credence to the possibility that the CineBench test is somehow flawed, our POV-Ray results return to where we'd expect them to be.
For those of you who don't fully understand how the 655K can be top of the "Per CPU" test, it's the total Pixels Per Second rendered, divided by the amount that did the rendering. As, within reason, the law of dimishing returns applies then a dual-core HT will naturally divide down much better than a quad-core HT. So average is how much speed you'll get, and the Per CPU is how efficient each core is working.
PC Mark Vantage
Boy oh boy. We've been hesitating to really emphasise how impressive it's been so far, but our PC Mark Vantage results leave no room for doubt. That lime green bar has been heading to the top, and it finally makes it. The i5-655K is seriously impressive.
Considering we've moved out of the realms of synthetic tests, and into real-world testing, it's jaw-dropping. Even the huge lead the 875K has enjoyed has evaporated.
