 Posted: Fri Nov 10, 2006 12:21 pm Post subject: Processor Comparison [Help Needed] |
 |
|
Hi Guys. So im still searching for the best hardware around for a PC upgrade, but need some help selecting a processor.
I narrowed it down to two, pretty similar ones. Intel® Core™ 2 Duo X6800 Extreme Edition Processor (2.93GHz, 1066MHz, 4MB) and the Intel® Pentium® Extreme Edition 965 Processor (3.73GHz, 1066MHz, 2x2MB)
Dell offers the Core 2 Duo processor almost £250.00 more than the Pentium Extreme.
My question to you guys is simple, what makes the Core 2 Duo that much better then the Pentium Extreme edition?
Both are 64bit, both have a 1066MHz FSB, and the cheaper processor is almost 1000MHz FASTER (GHz Wise)
The only visible difference I can see on the two processors is that the Core 2 Duo have one 4MB Cache and the Pentium Extreme has 2x 2MB Cache. Is this the only difference???
Any help would be much appreciated as im fairly pathetic when it comes to FSB's and Caches etc.
Thanks in advance guys lol

How many times do i have to tell you not to buy from dell.

Newer architecture and it takes alot less power! Also sse4 and ghz dont matter anymore.

Core 2 is a different world, as intel dropped their philosophy of sky-high clock frequencies and damn the efficiency. THat philosophy is reflected in the NetBurst processor, of which the P4 processor is the result of this style of NetBurst processor. Core 2 goes for effiency, buth in electrical power and clock for clock operations.
Of the two choices, the core 2 is the better option. You can plainly see from the CPU charts, from tom's hardware, the superiority of the Core 2 EE:
http://www23.tomshardware.com/cpu.html?modelx=33&model1=430&model2=436&chart=171
Also, DO NOT BUY A PROCESSOR FROM DELL!!! Buy from an online, or store dealer. They do have these in the UK, you will save a lot of money, and will also get the standard intel 3 year warantee.

Dell boi do you want me to explain why core 2 is much better then pentium D in extreme detail?

Ok you asked for it.
Basically it all comes down to the architecture,
For Core 2 it's.
| Wiki wrote: |
The P6 core was the sixth generation Intel microprocessor in the x86 space. The first implementation of the P6 core was in the design of the Pentium Pro CPU in the mid-nineties, the immediate successor to the original Pentium design (P5).
Some techniques first used in the x86 space in the P6 core include:
* Speculative execution and out-of-order completion (called "dynamic execution" by Intel), which required new retire units in the execution core. This lessened pipeline stalls, and in part enabled greater speed-scaling of the Pentium Pro and successive generations of CPUs.
* Superpipelining, which increased from Pentium's 5-stage pipeline to 14 of the Pentium Pro, and eventually morphed into the 10-stage pipeline of the Pentium III, and the 12- to 14-stage pipeline of the Pentium M.
* Integrated L2 cache that runs at the full speed of the processing core, instead of the earlier designs of off-die (on motherboard) cache, which runs at a fraction of the CPU frequency.
* Wider 36-bit physical address bus to support more than 4 GiB of physical memory (the linear address space of a process was still limited to 4 GiB).
* Register renaming, which enabled more efficient execution of multiple instructions in the pipeline.
The P6 architecture lasted three generations from the Pentium Pro to Pentium III, and was widely known for low power consumption, excellent integer performance, and relatively high instructions per cycle (IPC). When the new NetBurst (P68) architecture was conceived, initially in the Willamette core, which had relatively low IPC and less efficient overall design both in terms of power consumption and throughput efficiency, the P6 line of processing cores were largely thought to be abandoned. |
And Pentium D
| Wiki wrote: |
Hyper Pipelined Technology
Intel chose this name for the 20 stage pipeline within the Willamette architecture. This is a significant increase in the number of stages when compared to the PIII which had 10 stages in its pipeline. The Prescott achitecture, the last core of the Pentium 4, has a 31 stage pipeline. Although a longer pipeline has some disadvantages, mainly a reduced number of instructions per cycle, the higher number of stages in the pipeline allow the CPU to have higher clock speeds which will technically offset any loss in performance due to the reduced IPC. Another drawback of having too many stages in a pipeline is the number of stages that need to be traced back in case the branch predictor makes a mistake. The longer the pipeline, the further back in the process you have to trace in order to rectify the mistake, which increases the penalty paid for a misprediction. Keeping this in mind, Intel came up with the second feature in the NetBurst architecture, which is known as the "Rapid Execution Engine." In addition to this, Intel has invested a great deal into its branch prediction technology, which is capable at least 80% correct branch predictions.
Rapid Execution Engine
As per this technology, the ALUs in the core of the CPU actually operate at twice the core clock frequency. This means that in a 3.5 GHz CPU, the ALUs will effectively be operating at 7 GHz. The reason behind this is to generally make up for the low IPC count; additionally this considerably enhances the integer performance of the CPU. The downside is that certain instructions are now much slower (relatively and absolutely) than before, making optimization for multiple target CPUs difficult. An example is shift and rotate operations, which suffer from the lack of a barrel shifter which was present on every x86 CPU beginning with the 386 (and is also present on Athlon and Hammer).
Execution Trace Cache
Within the L2 cache of the CPU, Intel has incorporated what it calls an Execution Trace Cache. This cache stores decoded micro-operations, so that when executing a new instruction, instead of fetching and decoding the instruction again, the CPU can directly access the decoded micro-ops from the trace cache, thereby saving a considerable amount of time. Moreover the micro-ops are cached in their predicted path of execution, which means that when instructions are fetched by the CPU from the cache, they are already present in the correct order of execution.
Despite all these enhancements, today the NetBurst architecture has not proved to be very successful in terms of performance. With this architecture, Intel was looking to touch speeds of 10 GHz, but with rising clock speed, Intel has faced increasing problems with keeping power dissipation within acceptable limits. Intel has reached the limits at a speed of 3.8 GHz and has encountered problems trying to hit even that. As a result, newer Intel roadmaps clearly indicate abandoning NetBurst and adopting a newer microarchitecture, known as Core microarchitecture (inspired by the Pentium M), to help them achieve their goals.

Thanks alot for getting it for me, so now I know to stick with Core 2 Duo, at least until the next big thing is released.
Would the lesser priced Intel® Core™ 2 Duo Processor (2.66GHz, 1066MHz, 4MB) be a better buy then the Pentium Extreme Edition? 2.66GHz seems slow in my estimation, but the large price tag leads me to believe its worth my attention.

How can i put this man It would (Murder it worse then when i kill spammers hell even the e6300 matches it.
Heres a real easy explanation on core 2 duo power
It would take an X2 at 570-670mhz Clock advantage to beat a core 2.(Depending on Cache)
It would take a Pentium D at 1.2-1.3ghz Clock advantage in order to to beat an X2.
(Also the Core Duo has a 100mhz advantage over the x2 so you do the math)
The e6300 will Match an X2 4800 and Pentium D EE 965
(And kill anything lower)
The e6400 will kill the FX-62 and Murder the Pentium D EE 965
While the e6600 and e6700 will Murder Anything else twice over.
Get it dell boi Even the e6400 for 220$ (in america) will kill the EE 965 at 1000$ You would be a moron to buy any netburst unless you get the Pentium D 805 which is like 90$ now.
-----------------------------------------------------------------------------
Btw Dell boi heres an even simpler chart to tell who kills who.
X6800
QX6700(Quad Core)
E6700
E6600
E6400
FX-62
FX-60
X2 5200
X2 5000
E6300=X2 4800=Pentium D EE 965
X2 4600
Pentium D 960
Pentium D EE 955
X2 4400
X2 4200
Pentium D 950=Pentium D 945
X2 4000
X2 3800
Pentium D 940
Pentium D 840
Pentium D 930
Pentium D 925
Pentium D 830
Pentium D 915
Pentium D 820
Pentium D 805
---------------------------------------------
The e6300 will beat any X2 that has a clock advantage up to 570mhz
The e6400 will beat any X2 that has a clock advantage up to 670Mhz
The e6400 and e6600 have no rival from amd.

Did you even look at the THG processor charts that I posted a link to, dell boi?
You can select the processors you want to compare and the comperison test used to compare those processors. You can choose any processor and any application and get real-world data back from the tests that tom's hardware has done. While some processor charts from the manufacturers may be slightly skewed, the THG charts are a objective, third party resource.
Tom's hardware is based in Germany, over in Euirope. They have several places where they acquire their hardware, none of those being Dell. You can buy your hardware from online companies and build it yourself. This is a way of choosing all the highest quality parts, which you can't get from any OEM [barring of course local computer building shops]. Just look around for a bit and you can find some really good deals on all the hardware you will need.
Also, try and see if you can buy the nForce 680i motherboard. It's the best board for overclocking the EE Core2 processor, also it has the abitlity to do SLi. Couple that with two of the GeForce 8800's and you'll ahve an awesome machine, albeit really expensive.
the THG cpu charts can be found here:

Hi there, I just looked and I was quite shocked how the Core 2 Duo was so far ahead of the P4 EE. Thanks alot for this link, very helpful
