Formerly,
most ITX platform spec is always using NoteBook CPU and SO-DIMM.
These
components raise the system cost and the MB price is also much higher than ATX
MB.
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
well.
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
G620T, the price is little higher than G620. The internet shows 7USD
higher.
The “T”
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
setup.
Right is Intel bundled cooler and you can see the difference in
following picture.
Intel
Pentium Processor G620T, clock is 2.2GHz.
Physical 2 Cores don’t
Hyper-Threading and maximum is 2 threads, called 2C/2T.
It’s 32nm, 35W max
TDP, and 3MB L3 Cache. It’s LGA 1155 entry 2 Cores CPU.
Original
Cooler Comparison
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.
MB is
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 PWM
is 4+1 phases. As H61 cannot adjust multiplier, this is enough for Core i7.

CPU ratio can be lower. DDR3 clock for G620T is 800 and
1066MHz.
Integrated Graphics clock adjustable range is wider.

Related Technology
CPU cores can be adjusted and C1E is power saving
feature.
DDR3
set as CL6 7-6-18 1T to enhance bandwidth.
Voltage
Page
G620 CPU default voltage is 1.065V in MB and G620T is 1.020V.
The
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.
PC
Health Status
In LGA
1155 generation, if you want to OC, you need K sku CPU and P67/Z68 MN.
For
ITX platform, I don’t need it. Also, Sandy Bridge performance is also
improved.
The key point of ITX platform should be lower power consumption or
heat.
You can fine tune the system parameters by BIOS.

The
platform performance is 2~3 times faster than AMD ITX E350 APU.
Sandy Bridge
single CPU execution performance is very high. In dual core, the score is even
higher.
This ITX platform performance is good enough for HTPC. If you use
Celeron G530, the platform will be cheaper.

In
Sandy Bridge structure, DRAM performance is much improved. These years, I have
shared several Intel ITX platforms.
For ADIA64, same built-in IGP ITX
platform, LGA 1156 is 7641 MB/s and LGA 775 is 5930 MB/s.
G620T improves 161%
and 208% performance. For AMD E350 APU, it’s 3936 MB/s. The bandwidth gap is
even bigger.
For DRAM performance, the improvement can break users’ bad image
of ITX is low performance platform.

Intel Burn Test v2.4，Stress Level Maximum
Comparing
to G620, G620T temperature is acceptable.
G620T CPU full speed is 3~4˚C
lower. I think it will be better if the difference can be more than
5˚C.
However, 2 coolers thickness are different. It may causes G620T be
hotter.
For normal usage, the open air burning temperature not over 50 is
very good.

Intel 32nm and higher single thread performance, the dual core CPU can
achieve lower temperature, lower power consumption and high performance in ITX
platform.

Intel
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
increases 25~36%.
As built-in IGP performance, it’s only for low 3D demand
users. It’s not easy to replace entry VGA products.
Now, most ITX MB
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
test.
Core/Memory clock are 675/1600MHz. It’s Low Profile which compatible
with ITX.
It’s 1GB
DDR3 and chipset is AMD Radeon HD6450.
This is OC version. The default clock
is higher than HD6450. The price is in entry segment.

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.
HD6450
performance is for your further upgrade reference.
If you are not ITX case
users, you can choose other better performance cards.
GIGABYTE
H61N-USB3
Good
1. Support D-SUB / DVI / HDMI display mode and S/PDIF
fiber/coaxial output
2. 4 USB 2.0 and 2 USB 3.0 for upgrading USB wireless or
more.
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.
5. Built-in IGP 3D performance is much
improved comparing to LGA 1156. The DDR3 bandwidth is also
enhanced.
Weakness
1. Only support 2 SATA.
2. Price could be
lower.

ITX
platform for HTPC also needs to consider the HD video playback
perforamcne.
It’s not a problem for Intel platform. My previous review used
to share the Intel HD Graphics playback performance.
When playing 1080P
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. It’s very suitable for HTPC or high performance small PC.
If they
can change to 4 SATA and lower price, this will be high C/P ITX product.
CPU
options are wide. You can choose by budget, for more hi-end Core i3 or i5
CPU.
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
competition.
It will make price be parity which is good for users.
This
review is using rare Intel G620T version. Taiwan disti doesn’t sell this
version.
However, I still would like to share with who love ITX platform.
