Intel’s Latest 32nm Clarkdale Platform - Core i5 661 With BIOSTAR H55 OC 5G On Air

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.

Finally, add CPU voltage, challenge high clock “5GHz” by air cooling

CPUZ certification

Intel Core i5 661 OC 5G / windwithme

About 1.476~1.488V, this range can provide enough voltage for 5GHz into OS.

If you want to use Super PI and same level software, I think adding voltage up to 1.52 ~ 1.56V for CPU is necessary.

E8400~E8600 also can make CPU run at 4.8~4.9GHz, but voltage and temperature of 32nm are lower.

In the future, if Intel makes 32nm better, overclocking dual-core CPU to 5GHz will not be just a dream.

BIOSTAR T-Series TH55XE

Merits:

1. The design of package makes the product look high quality.

2. The range of BIOS voltage setting is wide; external clock and other options are also plentiful.

3. Power consumption of H55 chipset is very low.

4. Overclocking can make CPU/DDR3 reach 200/2000 steady level.

5. CPU power supply material is applied by better phase design.

Demerits:

1. The price of all H55 MB is still too high now.

2. Due to Intel’s structural design, i5 CPU built-in GPU can not show good performance on DDR3.

Performance:??????????

Material: ??????????

Specification:??????????

Appearance:??????????

Price:??????????

Price of most H55 MB is about NT$4200 (about US$130).

Although the price of BIOSTAR T-Series TH55XE is about US$117, it is a cheaper choice.

But I think the price of H55 chipset is still too high; if its price can be reduced to US$100, the product must be more popular.

About Clarkdale CPU, there will be both Core i5 6XX and Core i3 5XX series,

and the main difference is supporting TurboBoost or not.

I find some quotations about this kind of CPU from other websites:

Core i5 6XX: US$176~284

Core i3 530/540: US$113/133 respectively; and the price of Intel Pentium G9650 without HT technology is US$87.

My personal thinking of “All in One MB” platform, at the initial stage the price of the CPU product that consumers can accept is about US$90 ~ 110.

Therefore, Core i3 530 and Pentium G9650 are the products that can fit in with most consumers’ budget.

My experience about testing Clarkdale platform this time

Supported by 32nm new technology, the CPU,

compared with 45nm, has higher clock, lower temperature and power consumption, all of which make a great impression on me.

But now owing too high price, Intel still leaves something to be desired to make its products accepted by more consumers.

I feel very happy that besides AMD platform, Intel also releases higher performance All in One chipset.

Although current Clarkdale C/P value is not high, anyway Intel finally makes great progress on this product field in 2010.

I also expect the parity of this new platform is coming soon.

The release of Clarkdale provides one more choice in the market,

and makes the performance of Intel All in One chipset greater in the future.

By the way, I'm also enjoyed the world of DSLR;

I actually already had 4 of them since last year, including my latest one - a CANON KISS X3 Kit (500D).

In the coming February, I'm going to share my experience of the CANON KISS X3

And again, I truly appreciated for all your support, feedbacks, or even one simple comment;

that gives me the power and encourages to continue my sharing. Thank you

5Ghz ad aria con un Westemere ? Questa sì che è una cpu vera dual core.

beh è un suicide screen, non è certo da tenere per il daily

Thanks for the very good review Windwithme :n2mu:

And very nice OC capabilities of Clarkdale. Moreover, H55 chipset too, seems to be not bad

That's impressive, man! :AAAAH:

5Ghz ad aria é un suicidio per il Daily per il Vcore troppo alto o per altri motivi ?

Fantastic Review

no si dice suicide screen semplicemente perchè crasha come niente in quelle circostanze

ma non è che muore la cpu...si suicida solo il sistema operativo

Pensavo che arrivandoci con un Vcore troppo alto allora poteva creare seri problemi col tempo, se crasha Windows dettagli

col tempo si ...ma essendo appunto un suicide screen non credo che stai molto tempo in quelle condizioni...è già tanto che apre cpu-z...

in ogni coso è ovvio che non si puo' tenere per il daily una cpu 32nm a 1,5V... a meno che non pensi di cambiarla dopo 1 anno

[swattolo]

io sinceramente con sta storia del V-core non c'ho capito un tubo, io ho un 90nm e ho la cpu @ 1.5875V da Bios, defaut 1.4V e vorrei che un paio di anni li facesse, non é che rischio tenendola così ?

[Le085]

più il processo produttivo è alto e piu' sopporta tensioni alte

per un p4 1,5875 non è tanto
