Intel Pentium G620T with GIGABYTE H61N-USB3 Parity ITX Performance Review
most ITX platform spec is always using NoteBook CPU and SO-DIMM.
components raise the system cost and the MB price is also much higher than ATX
In the past 3 years, HTPC market started to ramp. ITX products are easier
to find now.
In the past, AMD ITX platform is easy to find due to its
high 3D performance IGP.
Since Intel LGA 1156 IGP performance caught up AMD
and Sandy Bridge is 3~5 times faster 3D performance.
Many MB makers launched
H67 or H61 ITX MB and the price is much lower.
Mostly, the price is only a
little higher than same level ATX or M-ATX boards. It can help HTPC buyers to
lower their budget.
So far, H61 is the lowest chipset for LGA 1155
platform. This segment competition is also very high, so the C/P is very
For CPU, Intel naming rule is the same. Pentium and Celeron series is
also in Sandy Bridge dual core CPU line.
This time, I use Intel Pentium

means low heat version. The clock and voltage is lower.
It’s a pity that
Taiwan doesn’t phase in this CPU. You can use G620 instead of G620T with same

Left side is Intel 2 Cores CPU version. Celeron, Pentium or
Core i3 use this model.
Right side is G620T one. You can see it’s thinner and
smaller. It’s easier to install in compact case.
GIGABYTE new H61N-USB3. It’s Mini-ITX and size is 17 X 17 cm.
Even though the
price is higher than M-ATX H61 USB3 MB, it’s still very parity ITX MB comparing
to the past.

CPU ratio can be lower. DDR3 clock for G620T is 800 and
Integrated Graphics clock adjustable range is wider.
CPU cores can be adjusted and C1E is power saving

G620 CPU default voltage is 1.065V in MB and G620T is 1.020V.
voltage gaps are not big. You can set manually to lower the voltage. As the pic,
I lower to 0.800V and it passed the burning test.
DRAM voltage also drops
from 1.500V to 1.300V. It can lower power consumption and heat.
1155 generation, if you want to OC, you need K sku CPU and P67/Z68 MN.
ITX platform, I don’t need it. Also, Sandy Bridge performance is also
The key point of ITX platform should be lower power consumption or
You can fine tune the system parameters by BIOS.

Sandy Bridge IGP 3D performance is much higher than LGA 1156.
If you have
more performance demand, you can consider Intel HD3000 series. However, the CPU
price is much higher.
The OC range is still ok. After OC, the 3D performance
As built-in IGP performance, it’s only for low 3D demand
users. It’s not easy to replace entry VGA products.

provides one PCI-E X16 for future upgrade.
Most ITX Cases are only compatible
with Low Profile VGA.
This time, I use GIGABYTE R645OC-1GI for 3D
Core/Memory clock are 675/1600MHz. It’s Low Profile which compatible

This is OC version. The default clock

HD6450 is AMD latest entry 3D graphic chipset. The performance is 2 times faster
than Intel IGP.
For Low Profile spec, the performance will be lower than
standard size VGA, due to dimension, temperature and power saving.
performance is for your further upgrade reference.
If you are not ITX case
users, you can choose other better performance cards.
1. Support D-SUB / DVI / HDMI display mode and S/PDIF
2. 4 USB 2.0 and 2 USB 3.0 for upgrading USB wireless or
3. Support Sandy Bridge series CPU. You can use LGA 1155 CPU from
Clereon to Core i7.
4. With 32nm entry dual core CPU, the temperature and
power consumption is outstanding.

Blue-Ray video, the CPU utilized rate is only 10%. You don’t have to worry about
the quality in latest platform.
GIGABYTE H61N-USB3 provides quite good IO

options are wide. You can choose by budget, for more hi-end Core i3 or i5
If you would like to build high performance ITX within budget, you can
choose Celeron G530 or Pentium G620.
Recently, I saw FM1 APU A75 chipset also
has ITX platform. I am glad to see more MB makers to join this
It will make price be parity which is good for users.
review is using rare Intel G620T version. Taiwan disti doesn’t sell this
However, I still would like to share with who love ITX platform.
