In the past six months, we often saw a lot of news about Intel 32nm CPU on the internet;
more information was about Core i7-980X, also LGA 1366 6 physical cores + 6 virtual HT cores (12 Threading).
The orientation of 32nm CPU belongs to Intel future highest-level LGA 1366 platform,
which most consumers show less interest in because of higher price.
Now take a look at Intel LGA 1156 platform.
About this new product line, there will be some 32nm CPU products put on sale,
including Core i5 6XX and Core i3 5XX series, and named Clarkdale.
The market orientation of these two series is different from previous Intel CPU.
The main reason is that Intel defines new CPU structure, not putting GPU into chipset like before but into CPU directly.
Intel’s such new design will affect PC market style “All in One MB” is becoming the future.
On chipset side, Intel releases H55/H57 to support new CPU design, and main difference is with or without RAID function.
Same as P55 chipset, a single-chip is adopted in the new chipset;
I assume Micro-ATX form factor will be the main design for H55/H57 motherboards.
Of course, some manufacturers also released ATX form factor for higher-level H57, seeming to direct compete with AMD 785G/790GX.
Especially, Micro-ATX products of AMD hold a special attraction for consumers for a quiet sometime now.
Therefore, Intel wants to increase his market share counting on this new product line this time.
This time I used BIOSTAR T-Series TH55XE as my MB platform,
which using Intel H55 chipset without RAID function, and its street price is around US$115 (about NT$3750).
Firstly, we can see the black is the main colour for the package.
I think the matching colour is exactly moderate, and package design is very special.
Product manual, driver CD, related cables and IO panel are attached.

They can be overclocked with built-in GPU, with range from 133 ~ 2000MHz
For BIOS setting, I set steady configuration according to the ratio of CPU to DDR3 is 200 to 2000.
When external CPU clock is set over 166 ~ 175MHz, built-in GPU becomes unsteady.
So, if you want to overclock CPU over 200MHz, external VGA is suggested.
I find this special situation when I use Clarkdale;
one possible reason is that GPU is built in CPU, so the design affects overclocking capability indirectly.
Testing platform:
CPU: Intel Core i5-661 ES
MB: BIOSTAR TSERIES TH55XE
DRAM: CORSAIR DOMINATOR-GT CMG6GX3M3A2000C8

BIOSTAR’s exclusive software
TOverclocker, multifunctional OS software,
allows user adjust external clock, voltage, and performance modes from this programme directly.
Hardware Monitor
The upper software allows user to change boot logo directly; FOXCONN also had similar software before.
G.P.U Energy-saving software: it is suggested to disable this utility when overclocking to remain system steady.
BIOSTAR now provides more and more software and professional functions as a big manufacturer should have.
From software user aspects, I believe Biostar team should improve and make it more user friendly.
Below is the test result of Intel new 32nm platform.
CPU uses Intel Core i5-661, 4 Threading, clock is 3.33GHz, L3 Cache 4MB
GPU is 900Mhz, 87W, official price is US$196
Default performance:
CPU 133 X 25 => 3333MHz
DRAM DDR3 1333 CL9 9-9-24 1T
GPU 900MHz 128mb
Hyper 4 X PI 32M=> 18m 00.891s
CPUMARK 99=> 550
Nuclearus Multi Core => 13523
Fritz Chess Benchmark => 13.07/6273
CrystalMark 2004R3 => 155768
CINEBENCH R10
1 CPU=> 4832
x CPU=> 10794
PCMark Vantage => 10706
CPU voltage is only 0.948V when system is standby; the voltage rises to 1.128V when CPU is in full loading.
Moreover about TurboBoost, when the system is standby, only single core is used, and CPU clock also rises to 3.6GHz.
When dual cores are in process, CPU clock will change to 3.46GHz.
In other words, under the condition of single core, CPU multiplier can be plus X2; of dual cores, plus X1.
The default CPU clock of Core i5 661 is very high, and the performance of the CPU is also great,
suitable for non-conversion or drawing software.
For most software that do not support multitasking, CPU clock at this moment is more important.
3DVANTAGE => 486
StreetFighter IV Benchmark
1024 X 768 => 7011
Clarkdale shows similar performance in 3DMARK2006 and 3D like 785G.
However, H55, without overclocking, gets higher scores in 3DVANTAGE than 785G. StreetFighter IV also shows high performance;
of course, built-in GPU products are what we use to compare.
The result also means Intel has made great progress in GPU design.
PSU is quiet in latest series E7 Cable Management, watt is 480W
Module design makes it easier to place cables in order.
When H55 platform is used as word-processing, 350W PSU is enough to support the system.
But if running at higher-performance VGA or hard drives will be added in the future, 400W ~ 500W PSU are recommended.
Test of power consumption
Standby: - 34~39W
When CPUZ displays 3600MHz, this condition means single core is being used.
Full speed: - 79~89W
When CPUZ displays 3466MHz, this condition means 2 physical core + 2 virtual HT cores are being used.
The combination of Intel Core i5 661 and H55MB saves more power;
when the system is in standby mode, the lowest power consumption is only 34W.
And, the range of power consumption is 79 ~ 89W when CPU is at the full speed 3.46GHz;
hence, 32nm platform can save more power than ever.
But I also find that different PSUs bring dissimilar results: when the system is standby,
the power consumption is mostly 38 ~ 42W for common 400W PSUs; and, 34 ~ 36W for 480W PSU (80 PLUS also help save energy).
OC performance
CPU 200 X 23 => 4600MHz
DRAM DDR3 2000 CL8 8-8-24 1T
GPU 900MHz 128mb
Hyper 4 X PI 32M=> 12m 49.813s
CPUMARK 99=> 709
Nuclearus Multi Core => 17945
Fritz Chess Benchmark => 17.69/8489
CrystalMark 2004R3 => 219569
CINEBENCH R10
1 CPU=> 6371
x CPU=> 14569
PCMark Vantage => 15076
When Core i5 661 is overclocked to 4.6GHz, 1.3V voltage can make the system steady.
32nm design makes dual-core CPU total clock raised 300 ~ 500MHz further.
H55 does not provide RAID function, so I used a SDD to test transfer rate.
CORSAIR CMFSSD-64GB2D, specification is 220/120 MB/s
From the test of SDD with high transfer rate, I find read/write performance of H55 is less 5 ~ 10MB/s than ICH10R.
I think the possible reason is deviation value, or the performance of single chipset could be lower.
As result, H55 shows fine performance on HDD.
GPU OC 1167MHz 128mb
3DVANTAGE => 563
StreetFighter IV Benchmark
1024 X 768 => 7455
Users can overclock built-in GPU by BIOS options.
The GPU performance can be raised 15 ~ 20% after overclocked.
DRAM performance test
CPU 133 X 25 => 3333MHz
DRAM DDR3 1333 CL9 9-9-24 1T
Sandra Memory Bandwidth - 11709 MB/s
EVEREST Memory Read - 9259 MB/s
CPU 200 X 23 => 4600MHz
DRAM DDR3 2000 CL8 8-8-24 1T
Sandra Memory Bandwidth - 17848 MB/s
EVEREST Memory Read - 13613 MB/s
About DDR3 2000, BIOS setting is CL8, but CPUZ shows CL9, EVEREST CL10.
I’m not sure why they are different; probably something related to BIOS setting.
Concerning DDR3 bandwidth performance, I thought Clarkdale can show great result like P55 dual-channel/ X58 tri-channel.
The design that Intel makes Memory Controller built-in can make the bandwidth of these new platforms 150~250% faster than LGA 775.
It's pity not able to take advantage on its high bandwidth infrastructure due to GPU engine integrated inside Clarkdule Core i5 processor.
