Running Time => 5m 19s
x264 FHD Benchmark => 25.2

PCMARK7 - 6108

Windows8 Experience Index - CPU 8.2

When OC i5-4670K to 4.5GHz, same as previous i7-4770K test, the single thread performance is almost the same.
As multitasking, due to the 4C4T and 4C8T difference, 4770K performance is 19-29% higher.
i5-4670K performance is more than enough for general users. The air cooling OC ability is almost same as i7.
As less thread and less cache, sometimes you can pull 100MHz more for OC range.
If you need multitasking graphic files converting, i7-4770K should be better. Of course, you need more budget for it.

DRAM Bandwidth Test
DDR3 3001.2 CL11 14-14-36 1T 1.668V
ADIA64 Memory Read - 30898 MB/s
Sandra Memory Bandwidth - 28691 MB/s
MaXXMEM Memory-Copy - 30715 MB/s

Intel Haswell DRAM is really improved. This is always the advantage for new platform.
If same DDR3 2800 clock, bandwidth is 13-27% higher than Ivy Bridge.
DDR3 extreme clock also can reach 2800~3000 from former 2666~2800.
Haswell structure improves Memory Controller design.
As good quality DDR3, Z87X-OC can reach 3000 easily.
Z87X-OC bandwidth is lower others Z87 about 5%. It may be caused by default latency settings.

3D Performance Test
PowerColor AX7970 3GBD5-2DHV3
3DMark Vantage => P32550

Unigine Heaven Benchmark 4.0
2560 X 1440 => 35.1 FPS

FINAL FANTASY XIV 1920 X 1200 => 11570

As CPU performance change, 7970 3D performance is also connected.
4670K OC to 4.5GHz bundles with AMD most high-end 7970 single core GPU, you can have very good 3D scores.
I use 2560 X 1440 high resolution to test Unigine Heaven Benchmark 4.0.
I still remember the same 7970 card, ver3.0 with 1920 X 1080 can reach 100 FPS.
It?s possible that 4.0 need more 3D performance. Also, higher resolution does drain 7970 performance.

Power Consumption Test
Enter to OS Desktop - 58W

Running ADIA64 to full speed 4670K - 138W

Running ADIA64 to full speed both 4670K and 7970 - 315W

When i5-4670K run at 4.5GHz, same as i7-4770K, 4670K standby is 7W lower and full speed is 35W less.
315W doesn’t mean CPU and GPU are both full speed. Running FurMark to full speed 7970 already takes 250W.
If adding CPU, HDD, SSD, DVD, I suggest you using 500W more Power supply.
Haswell is 22nm design. The power consumption is similar to Ivy Bridge.
