Xeon 1Ghz vs P3 1Ghz... whats the *REAL* difference guys?

[THELAIR]

Other than the price difference between uber dual xeon motherboards and cheapo's like the abit VP6.... what are the real advantages of going with the Xeon over the P3 realizing that they both operate at the same clock speed and both have the same l2 cache 256k.

Has anyone taken a benchmark of the 256k xeons and compared them to an equal P3 just to prove the point that i read on here that "there isn't a difference" ? Would be interesting...

so anyone got a 1Ghz Xeon and wanna compare it to their 1Ghz P3? 🙂

No real differences outside of a bigger connector to fit slot-2 mainboards. The GX chipset has other features as well but these don't add up to the difference in price you pay.

Cheers!

Difference depends on what you're doing on your computer. If gaming is your main priority, you won't see to much performance difference, however if you work in ProEngineer, CATIA or any other CPU intensive program, difference is very noticable.

 

[THELAIR]

andrey, this would be for a database server system, not a gaming machine.

How does a Xeon perform those programs you mentioned below better than a standard P3 ?

Im familiar with the differences between single and dual cpu systems and the applications that take advantage of them. My question is and still is, how does a Xeon 1GHz CPU compare to a P3 1GHz in standard benchmarks.

 

[GoSharks]

they are the exact same cpu, just with a different way of connecting to the the mobo. now if we are talking about the xeon 700 with 2meg cache and a p3 700, there are major differences. but there are none to be found at 1gig, just the name

 

[borealiss]

i think the xeons that have 256k l2 cache are able to be configured for systems with more than 2 cpus.

 

[esung]

no.. the 256KB L2 version only supports 2-way, and essentially it's the same as the P3. but the 700Mhz with 2MB on die cache CPU can do 4 way.. which is the true Xeon.. I consider all other stuff *fake Xeon*

 

[THELAIR]

So with the soon to disapear P3, the only real 2 way SMP options will be the 1ghz xeon? Unless intel creates a higher htan 1.5ghz P4 that is capable of running in tandem with another processor?

interesting

🙂

were or were is AMD!! Need that 760MP chipset!! 😀

 

[Smbu]

If you want a dual system just use 2 1ghz P3's(2 cB0, or two cC0 cpu's). It will certainly be a lot cheaper than 2 1ghz Xeon cpu's.

my dual p3-700 bit p3 xeon 667 long far away according to sisoft.

Where have you been?

Read Anand's Report on IDF (Intel Developer Forum)

Pay attention to pages 5, 6, and 7 about the next Xeon

 

[MadRat]

Wasn't that the McKinley in dual, though? Not exactly an x86 32-bit processor.

No...Read more carefully, the McKinley stuff wasn't really talked about until page 11 🙂

This is the processor codenamed &quot;Foster&quot;. Take directly from Page 5:

<SNIP>
&quot;We've introduced you all to Intel's server version of the Pentium 4 processor before, going under the codename Foster. The Pentium 4 is strictly a uni-processor CPU, meaning that it won't even work in a multiprocessor board, Intel made it very certain that only Foster would be used in the server market. We all expected Foster to be called the Pentium 4 Xeon, much like how the Pentium III Xeon was named after its desktop father, the Pentium III. However in an unexpected but highly foreshadowing move, Intel has decided to call the Foster nothing other than the Intel Xeon.

Not only does this create the Intel Xeon brand, but also it more importantly differentiates the product from the Pentium 4. This is the biggest hint that the upcoming Xeon will have much more than a larger cache to boast as advantages over the desktop Pentium 4. The Intel Xeon will be based on the same NetBurst Architecture as the Pentium 4, but that's where the similarity may end.

The current speculation happens to be that the Intel Xeon will feature something known internally to Intel as Jackson technology.

Jackson technology is supposed to bring Simultaneous Multithreaded (SMT) functionality to a processor's core. To give a brief overview, the limitation of a single processor is that on the hardware level it can only execute a single thread at one time. The beauty of SMT is that it allows the processor to execute more than a single thread at once.&quot;
