Upper-Left Corner
It’s 5 phases PWM design, 3 for CPU, 1 for GPU and 1 for MCH. Upper left is 4Pin power in connector.


IO
1 X PS2 KB/Mouse
1 X D-Sub / DVI-D / HDMI
4 X USB 2.0(Black)
2 X USB 3.0/2.0(Blue)
1 X RJ-45 LAN
3 X Audio jacks


UEFI Screen
Intel Core i5-3450 default clock is 3.1GHz. I enable Turbo Boost 2.0 to boost the single core to work at 3.5GHz. 4C4T full speed can reach 3.3GHz.
If using same brand H77, the max CPU Clock Ratio is 35.
When using Z77, the max CPU Clock Ratio up to 37. That’s why I am using Z77 here.


CPU ratio adjusts to 37, disable C1E and EIST, power saving features. You can set CPU clock at 3.7GHz.


Testing Configuration
CPU: Intel Core i5-3450
MB: GIGABYTE Z77M-D3H
DRAM: CORSAIR CMZ16GX3M2A1866C10R
VGA: Intel HD Graphics 4000
HD: CORSAIR Performance Pro 256GB SSD
POWER: CORSAIR AX650W
Cooler: Intel Original Cooler
OS: Windows7 Ultimate 64bit


The comparison is between default and OC mode.
The 1st picture is default.
CPU 100.1 X 31 => 3100MHz
Enable C1E and Turbo Boost, the clock will floating between 1600 to 3500MHz by CPU utilization rate.
DDR3 1334.8 CL7 8-7-21 1T

The 2nd picture is after OC.
CPU 100.1 X 37 => 3703.79MHz
DDR3 1868.6 CL10 11-11-30 2T, enable XMP mode.

Hyper PI 32M X4 => 10m 59.772s
CPUMARK 99 => 550


Hyper PI 32M X4 => 9m 39.354s
CPUMARK 99 => 585


CPUMARK 99 only test single core, so the performance of 3.5GHz and 3.7GHz are similar.

Nuclearus Multi Core => 19550
Fritz Chess Benchmark => 20.39/9787


Nuclearus Multi Core => 22682
Fritz Chess Benchmark => 22.93/11005


Fritz Chess Benchmark only test CPU multi-tasking 4C4T computing capability. The performance increase around 12.5%.

CrystalMark 2004R3 => 259729

Power Consumption Test
OC, OS Desktop - 46W


Comparing to temperature, the power consumption is affecting by C1E in default mode.
If you enable C1E in OC mode, the power consumption will drop a lot.

Default, running LinX to fully speed CPU - 75W


OC, running LinX to fully speed CPU - 80W


When i5-3450 full speed more, the power consumption is only 5W as 400MHz clock difference.
Ivy Bridge 22nm manufacturing save power more than 25~35% comparing to Sandy Bridge.

Finally, I also test latest HD2500 IGP 3D performance.
i5-3450 OC to 3.7GHz and HD2500 default clock is 1.1GHz.
3DMark Vantage => P1988


StreetFighter IV Benchmark
1280 X 720 => 49.90 FPS


FINAL FANTASY XIV
1280 X 720 => 765


In 3DMark Vantage, HD2500 is similar to HD2000.
StreetFighter IV Benchmark improves 12% and FINAL FANTASY XIV improves 23%.
The 3D performance increasing range is not big but still helpful.
More accurate, HD2500 performance is still lower than former HD3000. User can notice by model name.
For Ivy Bridge structure, if you want to have better integrated 3D performance, you can choose HD4000 IGP.

GIGABYTE Z77M-D3H
Pros
1.Z77 series use white color packing and booting screen. It’s minimalist style.
2.Phasing in UEFI BIOS and providing two BIOS interfaces.
3.Built-in personal preferred Atheros LAN and VIA audio.
4.Micro ATX Z77 is lower price, but features and performance are standard level above.

Cons
1.CPU PWM better to have heatsink
2.Rare IO audio jacks better to have 6 for better function.



Performance ★★★★★★★★☆☆ 83/100
Components ★★★★★★★★☆☆ 82/100
Specification ★★★★★★★★☆☆ 79/100
Appearance ★★★★★★★★☆☆ 77/100
C/P Value ★★★★★★★★★☆ 86/100

As Intel launched latest Ivy Bridge structure this year, it includes CPU and chipset.
Entry IGP HD2500 is improved a little and high end IGP HD4000 improves a lot from HD3000.
CPU performance is 10~14% enhance from Sandy Bridge in same spec and clock.
Power consumption is much lower by 22nm implement.
CPU temperature is a little higher than Sandy Bridge, but it’s still affordable for efficient OC.



Ivy Bridge has Z77, H77 and B75 chipsets to complete the market segment.
The price is lower than 6 series within few months after launching due to tough competition in MB market this year.
Z77M-D3H price is only 17USD higher than H77M-D3H.
If your budget is higher, Z77 provides you better C/P certainly.
If you don’t OC, H77 is also alternative solution for you.
This article mainly focus on Intel Core i5-3450 and Micro ATX Z77 Ivy Bridge entry combo.
You can refer it if you have got i5-3450 or plan to buy i5-3470. :)
