Clarifying Core Confusion

This will clear up some of the con­fu­sion regar­ding Intel’s CPUs or pro­ces­sors. The naming con­ven­tions are simi­lar and requi­res some atten­tion to the detail. Lets be clear on “Core Duo” and “Core 2 Duo” and “dual core” and “Pen­tium D” processors.

Core Duo

The Intel Core Duo pro­ces­sor is a 32-bit CPU.  It has a 32 bit ins­truc­tion set. Core Duo pro­ces­sors are not offi­cially called “dual core”  pro­ces­sors. Core Duo pro­ces­sors do not have 64 bit ins­truc­tions sets and can­not run 64 bit ope­ra­ting sys­tems. That being said, Core Duo can­not run 64 bit games or appli­ca­tions.  “Core Duo” is an offi­cial Intel brand name.

Core 2 Duo

Core 2 Duo are 64-bit CPUs. They have 64-bit ins­truc­tion sets. They are back­ward com­pa­ta­ble with 32-bit ope­ra­ting sys­tems, games and appli­ca­tions. The Core 2 Duo CPUs are not offi­cially refe­rred to as “dual core” CPUs. “Core 2 Duo” is an offi­cial Intel brand name.

Pen­tium D

The “Intel Pen­tium D Pro­ces­sor” is an offi­cial name.  All the Pen­tium D Pro­ces­sors are dual core CPUs.  All are desk­top CPUs.  All Pen­tium D Pro­ces­sors are 64-bit.  Now get ready for this inte­res­ting tid­bit.  All Intel dual core CPUs are not Pen­tium D Pro­ces­sors.  They are not offi­cially bran­ded as Pen­tium D Pro­ces­sors.  The follo­wing is a list of Intel offi­cially named Pen­tium D Processors:

  1. 805
  2. 820
  3. 830
  4. 840
  5. 915
  6. 920
  7. 930
  8. 935
  9. 940
  10. 945
  11. 950
  12. 960

Extreme Edi­tion

There is still more core to con­si­der.  The “Pen­tium Pro­ces­sor Extreme Edi­tion” is an Intel brand name. They are not offi­cially called Pen­tium D.  Howe­ver, when you look at the Intel lis­ting, you could say they are Pen­tium D Pro­ces­sors on roids. There are only three of them.  These are an overclocker’s dream.  They are as follows:

  1. Extreme Edi­tion 965
  2. Extreme Edi­tion 955
  3. Extreme Edi­tion 840

They are all dual core, 64 bit pro­ces­sors for the desk­top.  Right now you could get great pri­cing on them.  But look out for the EE 965 can still be pri­cey des­pite its age.

Dual Core Pen­tium

Now we come to the cate­gory where the CPUs are called Pen­tium.  But they are dual core 64-bit pro­ces­sors.  They are all E-series desk­top pro­ces­sors.  They are as follows:

  1. E2140
  2. E2160
  3. E2180
  4. E2200
  5. E5200
  6. E5300
  7. E5400
  8. E6300
  9. E6500

These pro­ces­sors are pri­ced just right, in the $100.00 and less range.  Dont think they are out­da­ted.  The Pen­tium Pro­ces­sor E6500 was just recently laun­ced.  This one doesn’t even have a 64-bit ins­truc­tion set.  The E6500 doesn’t need it.  Why?  Because it has Intel 64.  It is a little dif­fe­rent from the others in this cate­gory.  It also sports a 45nm pro­cess, which is indi­ca­tive of  its edgi­ness.  Howe­ver, it is still in the low C-note range price-wise.

Sum­mary

This is not exhaus­tive.  There are still Cen­trino Duo and and other “dual core” mobile pro­ces­sors.  Well hit on them in the lap­top section.

Centrino Vs. Core 2 Duo

Intel’s Cen­trino and the Core 2 Duo pro­ces­sors are great in their own way. Deve­lo­ped exc­lu­si­vely for the mobile mar­ket, Cen­trino con­ti­nues to stay ahead of the pack. Both of these CPUs have 2 cores on one phy­si­cal pac­kage. Howe­ver, there is con­fu­sion about Centrino’s dif­fe­ren­ces and com­mon points.

What dif­fe­ren­ces exits? What are the simi­la­ri­ties? Here are some stats to help the rea­der bet­ter unders­tand the tech­no­logy being desc­ri­bed.

Centrino 

Cen­trino tech­no­logy ena­bles pro­ces­sors to have the best effi­ciency and the best bat­tery life. So far it is the best tech­no­logy to accom­plish that. The Cen­trino tech­no­logy is a collec­tion of per­for­mance and power mana­ge­ment technologies.

The Cen­trino pro­ces­sors follow a naming con­ven­tion simi­lar of Core 2 Duos. There is the Cen­trino pro­ces­sor, sin­gle core, opti­mi­zed for the mobile mar­ket. Then there are the Cen­trino Duo that has two cores and still 32 bit. Finally Cen­trino Pro and Cen­trino vPro which are spe­ci­fi­cally Mobile Enter­prise. The Cen­trino Pro and vPro incor­po­ra­tes Core 2 Duo tech­no­logy and have 64 bit ins­truc­tion sets.

Core 2 Duo

This is the best selling chip right now. There are seve­ral dozen Core 2 Duo pro­ces­sors for lap­tops. These pro­ces­sors are not spe­ci­fi­cally mobile CPUs. Neverthe­less, Core 2 Duo now has domi­nance in the mobile market.

The Core 2 Duo is avai­la­ble to a wider seg­ment of machi­nes nee­ding pro­ces­sors. Pro­ces­sor speed for mobile chips ran­ges up to 3.06 GHz. The 2 Duo pro­ces­sors for the desk­top have fre­quen­cies as high as 3.33 GHz.

Dif­fe­ren­ces

When it comes to mobile pro­ces­sing, Cen­trino tech­no­logy has a deci­ded edge. Cen­trino tech­no­logy was deve­lo­ped spe­ci­fi­cally for mobile appli­ca­tions. So the Cen­trino group are on the path of best prac­ti­ces to that goal. Which is why the newest Centrino’s have incor­po­ra­ted Core 2 Duo technologies.

The Core 2 Duo CPUs have not, as of yet, incor­po­ra­ted all that Cen­trino has to offer. The newest Cen­trino has Next-Gen Wireless-N. That is a wire­less tech­no­logy with up to 5 x fas­ter per­for­mance and 2 x WiFi range. Addi­tio­nally, Cen­trino spe­ci­fic tech­no­lo­gies are being por­ted to Core 2 Duo processors.

Sha­red Strengths

The Cen­trino 2 actually incor­po­ra­tes Core 2 Duo as a com­po­nent. There are both 64-bit Cen­trino and Core 2 Duo pro­ces­sors. The Core 2 Duo uses tech­no­lo­gies that ori­gi­na­ted with Cen­trino. These tech­no­lo­gies are now used on the desk­top and mobile.

Conc­lu­sions

When you peep under the hood of the Cen­trino you’ll find some engi­nee­ring that Core 2 Duo don’t have. The Cen­trino pro­ces­sor is quickly beco­ming the stan­dard for mobile enter­prise com­pu­ting. But Core 2 Duo is not left in the dust. They ascend to the pre­sent level and beyond only with a con­cer­ted effort. The latest Cen­trino CPU has Core 2 Duo as a component.

Core 2 Duo vs Turion 64

The Core 2 Duo is dif­fe­rent from the “Core Duo” and Pen­tium Dual. AMD’s single-core Turion 64 is dif­fe­rent from Turion 64 X2. The Intel Core 2 Duo is a 64-bit sys­tem, whe­reas the Intel “Core Duo” is a 32-bit sys­tem. We are only going to talk about the AMD Mobile Turion 64 single-core and Intel’s Core 2 Duo pro­ces­sors. This article can help in deci­ding on one of these processors.

AMD Turion 64

The AMD Mobile Turion 64 is a single-core 64-bit pro­ces­sor. This pro­ces­sor can run 32– and 64-bit ope­ra­ting sys­tems. There are seve­ral single-core Turion 64s in this cate­gory. They range from a CPU speed of 1 GHz to 2.4 GHz.

The Turion 64 ML and MT are com­pa­ti­ble with a Soc­ket 754-type CPU soc­ket, whe­reas the Turions desig­na­ted with “MK” are com­pa­ti­ble with a Soc­ket S1. The Turion 64-MK has the best per­for­mance of the family.

2 Duo Processor

Intel Core 2 Duo pro­ces­sor is 64-bit tech­no­logy. It is a two-core pro­ces­sor and can run both 32– and 64-bit ope­ra­ting systems.

Intel offers at least 57 types of 2 Duo pro­ces­sors for lap­tops. Their speed ran­ges from 1.06 GHz to 3.06 GHz. The L2 caches of these pro­ces­sors are lis­ted as 2, 3, 4 and 6 MB. The fre­quency of the front side bus is from 533 to 1,066 MHz.

2 Duo consumption

Per­for­mance for mobile chips is redu­ced as much as 25 per­cent from desk­top chips.

The alpha nota­tion of wat­tage and thus power con­ser­va­tion is:

The highest current con­sump­tion: X (extreme).
Desk­top pro­ces­sors over 55 watts: E
Regu­lar lap­top CPU 30–39 Watt : T
Lap­tops up to 25 watts: P
Low vol­tage CPU, 12–19 watts: L
Ultra-low vol­tage, less than 19 watts: U

Power Con­sump­tion of Turion

Turion’s power con­sump­tion is indi­ca­ted by its ther­mal dis­si­pa­tion rating. The ML has a TDP of 35 watts.

The Turion-MT has less per­for­mance but bet­ter power con­ser­va­tion. It’s TDP is 25 watts.

Power­Now! ena­bles the ML processor’s ope­ra­ting fre­quency to scale down. The hot­test Turion can cook at 2.4 GHz and cool down to 800 MHz. Of course, this is depen­dent on CPU load. The vol­tage sca­les accordingly.

Desk­tops

There are Core 2 Duo pro­ces­sors for desk­top com­pu­ters. They range from 800 MHz to 1333 MHZ FSB. The L2 cache sizes were 2, 3, 4 and 6 MB. The soc­kets were PLGA775, but the most up to date offe­rings are LGA775. The pro­ces­sor fre­quency was 1.80 GHz on the low end and went as high as 3.33 GHz.

AMD pri­ma­rily inten­ded Turion 64 for lap­tops. Repor­tedly, there are some ways to kluge a main­board with 754 soc­ket to per­form with a Turion 64 on the desktop.

Sum­mary

Both of these pro­ces­sors will ena­ble you to take advan­tage of a 64-bit ope­ra­ting sys­tem. There are more 64-bit games and appli­ca­tions beco­ming avai­la­ble. These games and apps require 64-bit pro­ces­sors and ope­ra­ting systems.

An AMD Turion 64 pro­ces­sor is a good option for a lap­top. Addi­tio­nally, the 2 Duo pro­ces­sors are for lap­tops and desktops.
