Intel Core i7 4770K (Haswell 4th Gen) CPU and Z87 Express Chipset Review (Page 4)

We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASUS, MSI, Western Digital, MemoRight and Corsair.

We've got a ton of CPU's here today that we'll be comparing against the new Haswell i7 4770Km which will be running at both stock and overclocked speeds, with the latter being covered in just a moment. From Intel we've got the i7 2600K, 3770K, 990X Extreme Edition, 3930K and finally the 3970X Extreme Edition. As for the AMD side of things, we've simply included the FX-8150.

Before we get into the performance side of things we need to look at overclocking. Like with any new platform, you don't really know where to start, so overclocking can initially be a bit slow, tedious and generally not as strong as later in the game. Heading into the BIOS for the first time we move straight down to the voltages. The one thing I absolutely love about ASUS boards is that as you up the voltages, the number changes color letting you know if you're still at a safe level or too high.

As we go through the voltages we move to the point where we hit the last "yellow" before it turns "purple", letting us know that we're going a little too high. Once we'd done all that we headed in to the multiplier area and started messing around. We started at 50x and found ourselves unable to get into Windows. We then moved to 49x and found ourselves having the same issue.

Moving to 48x resulted in a clock speed of 4.8GHz and we got into Windows with no problem. We then fired up MediaEspresso, which we've found to be our best benchmark when it comes to testing stability. Unfortunately we didn't get too far into the encode process before we got hit with a BSOD.

We moved down to 47x and while we got further into our encode process, we still ended up hitting a BSOD. It wasn't until we moved to the 46x multiplier and came in with a 4.6GHz clock speed that we finally found everything was stable. It's a little hard to completely judge the overclocking on the processor at the moment because as we test more boards, get more updated BIOS' and grow more accustom to overclocking the CPU, we'll achieve higher CPU clocks.

Anyway with that all said and done, it seems fairly safe to get into the benchmarking side of things and find out just what kind of performance we're able to get out of this new Intel setup.
