Intel Celeron 1.8GHz vs. Celeron D 2.8GHz

[chirantha7777]

This is very interesting. Here the specs of the two processors

Intel Celeron 1.8GHz

Model : 430
Speed : 1800MHz
Bus Speed : 800MHz
L1 : 32KB
L2 : 512KB
Power Consumption : 35W MAX

Intel Celeron D 2.8GHz

Model : 336
Speed : 2800MHz
Bus Speed : 533MHz
L1 : 16KB
L2 : 256KB
Power Consumption : 84W MAX

I ran a PHP loop count test on both servers and guess what the 1.8GHz Celeron out performed the 2.8GHz Celeron D.

Scores

Celeron 1.8GHz : 81000
Celeron D 2.8GHz : 54000

Celeron 1.8GHz is amazing! Not only does it use half the power consumption of the great Celeron D 2.8GHz, it out performs it. I also found that the Celeron 440 out performed the Pentium 4 2.8GHz!! using half the power again! I BET that this is reason Sri Lankan CPU importers don't import Celeron 440... and Celeron 440 is waaay cheaper than the Pentium 4 2.8GHz

Net burst has 2 instrucitions per cycle where the Core has 4 cycles.So no wonder it out performs.And The Pentium Ds are either 90nm or 65nm.So Intel Celeron Core based models out perform them.Ds are not native dual core but bridged two pentium cores.So the power consumption is high there too.

hmmmmmmmmmmmmm

haha! Conroe-L vs Netburst. no wonder

I don't think he's talking about the dual-core celeron of 1.8GHz. If it is, it simply rules out the pentium D. (1.4 x 2 cores) Increase of power consumption is due to 2 cores.

If it's the single core 1.8GHz processor, your program is only using the 1.4 core (single) of the 2.8, and hence lags it behind.

What are the differences between intel pentium & intel celeron??
I've heard that the Intel celeron processor is out of quality & makes very low performance while it uses the whole memory usage to perform a minor function!!
Is this true??

hmmm

Well processer clock speed has little to do with the speed. The actual processor speed is mesuered with MIPS (million instructions per second). Actually doubling the clock speed wont double your speed. it would give abt 17% of upgrade but no more.

But here one processor has 530 bus speed and other has 800 bus speed. Obviously 800 bus speed will perform well.

the main difference in celoron processors are they have less cache. Unlike normal RAM cache memory is expensive. Cache helps to store more information "INSIDE" the processor on large processing. otherwise getting the information allthe way from RAM would cost more and no matter what the processor speed is processor has to wait for information. Thats why it is said celoron is good for basic apps.

Running php loop cannot be considered as a good benchmarking to select best processor. Because the processors are not "stressed" enough. maybe try sorting algorithem. Looping are really straightfoward and doesnt revel anything.
