Intel Core i7-4770K loaded with BIOSTAR Z87X 3D overclocking share

At the beginning of June this year, Intel released a new generation of framework as scheduled, with the model name of Haswell
The pin of the last two generations is LGA 1155. It is the biggest difference that the new platform is changed to LGA 1150.
In a short time, Intel Core i series has advanced to the fourth generation of framework with better specification for each generation
The code of the most advanced chipset is Z87, bringing out the six SATA3 interfaces which have been waited for by many people for a long time
And CPU has recovered to the ability to exceed external frequency in the first generation of Core i, while the two aspects are both good improvements

The MB is BIOSTAR Z87X 3D, imitating design of Hi-Fi material as well
PCB uses black mist side material, cooling fin is blue, and color of appearance is similar to that of a middle and advance-level Z87

Hi-Fi Z87X 3D uses Z87 chipset, price of which is relatively fair compared with other brands in material and design
At present, BIOSTAR launches two Z87s in Z series, the other is Hi-Fi Z87W, belonging to a cheaper version

Intel has entered the fourth-generation framework of Core i series, names of CPU also begin with 4
The testing focus is the most advanced Core i7-4770K in Haswell framework, the codes followed by k all have function of adjusting doubling frequency
The CPU radiator is on the right, for 4 Cores CPU, Intel all uses radiators with copper material at the bottom

Total frequency of 4770K is 3.5GHz, supporting Turbo Boost technology, and top performance can reach 3.90GHz
Entity 4 Cores is integrated with Hyper-Threading technology, which can reach 8 threads in total, called 4C8T for short
It has the same 22nm manufacturing process with Ivy Bridge, with higher consumption of 84W, and 8MB of L3 Cache in total

BIOSTAR changes to the design style of the new version in UEFI interface
Some data of the current hardware are shown on the left,
the background is also changed to red which has the sense of speed, and the resolution is 1024X768
It offers English and simplified Chinese for switching

Main page of overclocking and effect adjusting

Main page of CPU effect adjusting
External frequency of 4770K is fixed at 45, i.e. 4500MHz
It closes CPU C status energy-saving technology, the lower part is the clock rate and options of built-in GPU

DDR3 uses CORSAIR Dominator Platinum 2800C11
It is able to reach stable high efficiency of DDR3 2800 easily after opening XMP technology

Voltage page
CPU voltage adopts options of increasing or decreasing, the CPU Voltage Offset(mV) is set as 120 overclocking of 4.5GHz
Then, CPU voltage will turn to 1.284V shown on the left

Without CPU of K version, it can also use external frequency for overlocking in the framework of Haswell, which is an advantage of the new platform
The above sets CPU and DDR3 respectively to 4500 / 2800MHz through the overclocking method for conducting doubling frequency and increasing voltage to 4770K
Because overclocking frequency of Haswell does not reach the stable level as the Ivy Bridge of the last generation which can reach 4.8GHz in the same air-cooled environment
While the following test will compare the performance of the two different frameworks once again, for the frequency is possibly not equal to efficiency after all

Testing platform
CPU: Intel Core i7-4770K
DRAM: CORSAIR Dominator Platinum CMD16GX3M4A2800C11
VGA: Intel HD Graphics 4000
HDD: Samsung 830 Series 128GB SSD
POWER: XIGMATEK Tauro 400W Bronze
Cooler: Thermalright Archon SB-E X2
OS: Windows8 64bit

Intel Core i7-4770K overclocking performance
CPU 100 X 45 => 4500MHz 1.284V
DDR3 2800 CL11 14-14-35 2T 1.668V

Hyper PI 32M X8 => 10m 30.456s
CPUMARK 99 => 781

It compares performance of CPU through 3770K OC 4.8GHz and 4770K OC 4.5GHz
4770K is 3.6% higher in CPUMARK 99

Nuclearus Multi Core => 33835
Fritz Chess Benchmark => 36.37/17456

3770K is 2.7% higher in Fritz Chess Benchmark

CrystalMark 2004R3 => 412719

CPU => 9.86 pts
CPU(Single Core) => 1.96 pts

4770K is 2.9% higher in multiplexing CPU performance
3770K is 4% higher in CPU (Single Core)

Running Time => 3m 49s
x264 FHD Benchmark => 29.9

4770K is 12.4% higher in x264 FHD Benchmark

PCMARK7 - 7596

Windows8 WEI - CPU 8.3

The frequency of stable running for the new generation of Intel i7-4770K in air-cooled environment is about 4.5GHz
It can be seen that most testing data are a little bit better than the last generation of i7-3770K overclocking 4.8GHz in performance
We can conservatively consider the highest air-cooled stable frequency of the two generations of 4770K 4.5GHz and 3770K 4.8GHz to be equivalent
The above is the performance comparison after overclocking, while defaults of the two types of CPU are 3.5GHz for the same, highest to 3.9GHz
Default performance of i7-4770K is more or less improved than that of the last generation, which is similar to advancement extent of each generation of Core i framework

DRAM bandwidth test
DDR3 2800 CL11 14-14-35 2T
ADIA64 Memory Read - 33686 MB/s
Sandra Memory Bandwidth - 31243 MB/s
MaXXMEM Memory-Copy - 32187 MB/s

The following is comparison between the two frameworks of Haswell and Ivy Bridge
Frequency is still set to DR3 2800 2T
i7-4770K is about 20% higher in Sandra Memory Bandwidth
i7-4770K is about 13% higher in MaXXMEM Memory-Copy
i7-4770K DDR3 2800 2T compares i7-3770K DDR3 2400 1T
ADIA64 Memory Read is about 27% higher, we are sorry for data contrast about ADIA64
Bandwidth data of 3770K DDR3 2800 1T is not tested before, estimating that it won?t exceed 27000 MB/s even for the same setting
Haswell framework has obvious progress in DDR3 bandwidth, and it is possible for the highest frequency to reach over 3000 if further adjusted

Intel HD Graphics 4600 performance test
GPU frequency is UEFI BIOS, 1400MHz by default
3DMark Vantage => P7553

StreetFighter IV Benchmark
1280 X 720 => 135.90 FPS

1280 X 720 => 2440

For Haswell framework, it is the built-in CPU that is improved the most in performance
Compared with the built-in HD4000 of the last generation of i7-3770K,
HD4600 increases 31% in 3DMark Vantage, and 17% in StreetFighter IV
FINAL FANTASY XIV also increases about 39%, which is an advantage for users who need built-in 3D
In environment of 1920X1080 high resolution, it can be used smoothly except for advanced 3D GAME or too many special effects enabled

Power consumption test
System standby - 64W

It operates IntelBurn Test to make CPU operate at full speed - 172W

4770K 4.5GHz with same 22nm manufacturing process is lower in power consumption than that in 3770K 4.8GHz
It can be considered the same power consumption, because the difference is only about 3~5W, and performance is similar, too

The radiator uses Archon SB-E X2 launched by Thermalright before
It is located on the advanced CPU radiator, supporting a fan of12~14cm on left and right sides
For users of LGA 1150 platform, it may make a fan stuck easily if working with the DDR3 with a high order cooling fin
This won?t occur if LGA 2011 platform works with the DDR3 with general height
