Which System is faster

[lambchops511]

System 1:

4 x Xeon @ 3.4 GHz

vendor_id : GenuineIntel
cpu family : 15
model : 4
model name : Intel(R) Xeon(TM) CPU 3.40GHz
stepping : 3
cpu MHz : 3400.232
cache size : 2048 KB

or

System 2:

1 x Core 2 Duo @ 2.1 GHz

vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Core(TM)2 Duo CPU T8100 @ 2.10GHz
stepping : 6
cpu MHz : 2100.998
cache size : 3072 KB


Running a single threaded task.

I'd rather the 2.1GHz Duo.

 

[rudeguy]

neither. Throw an AMD in that piece.

 

[ViviTheMage]

model name : Intel(R) Xeon(TM) CPU 3.40GHz and 4 of those Xeons would be nice 🙂.

T8100 is a laptop CPU ... toned down core 2 duo.

 

[darkxshade]

Depends if that task is Crysis

 

[lambchops511]

i have both system at my disposal to run a simulation (single threaded) that might take days...i need to know which one to choose....

 

[Modelworks]

Core 2 has larger cache, but if the program isn't cache bound I would go for the xeon.

might want to post in the right forum if you want an honest answer

 

[SlitheryDee]

The Xeons are P4 based? If so I would think the C2D would beat it in single threaded apps. Might be pretty close though.

 

[Rick James]

I'd take those 4 sweet Xeon's

You could run a single threaded benchmark test and then tell us which one is faster.

Both of these programs can provide computational tests that comparatively will tell you which system is faster.

FYI: i've for my multithreaded application (Integer CPU, some FPU, and lots of memory bound app) ... the Xeon system is significantly faster

Xeon

 

[RedArmy]

CPU Time = (Instruction_Count * CPI)/Clock_Rate
or
CPU Time = Instruction_Count * CPI * Clock_Cycle

You might need to do some calculations with MIPS/MFLOPS in conjunction with using Amdahl's Law for multicore processors/if you start tweaking stuff

 

[Homerboy]

Uhhh "single task" doesn't mean crap... whats the single task?
oh and wrong forum.

 

[mobo198]

go for the duo

 

[Colt45]

The xeons can do more NOPs per second, if that's what you're asking. Not that that means anything IRL. 😀
