Intel EE 840 Vs AMD Opteron(sp)

post #1 of 9
Thread Starter 
ok, many people have told me go with AMD , but I dont see why, am I over-seeing somthing? I mean as far as I know they both use the same princaples , I know AMD chips are better for overclocking but, can the ability to increase the muliplier make the difference when the stock EE has a clockspeed of 3.2 compared to the Opyerons 2.4?


note: sorry didnt know weather to put this in the Intel CPU subforum or AMD

The difference is AMD has 3DNOW technology which maked it better for gaming and AMD do 9 operations every clock cycle as INTEL only do 6 but Intel is much better for multimedia and is also good for gaming so ive always gone for intel because of that.

operations per minute? I thought speed was measured in Ghz?

I think ill stay with Intel, not shure, I know I can overclock it to 4Ghz, ive seen it done so um right now i gues my Q is

what is the highest clock speed possable for the EE and the Opteron using 4 Gigs of memory?

I Love Trek BTW

I <3 intel, they're so dependable, I've never used amd, I've been with intel ever since my p1 system.

each operation is messured in Ghz, so to find AMD's clock speed compaired to Intel you have to x1.5 it ex: 2.4 Ghz in AMD = a 3.6 Ghz Intel

That's exactly the problem really, they don't work on exactly the same principle. In the simplest terms I can put it, an AMD Athlon (or Opteron since it's basically the same) is capable of doing more operations each clock cycle, each hert (MHz being million cycles per second). The exact numbers are 9 and 6, the Intel Netburst architecture (P4, PD, Xeon, etc.) doing six floating point operations each clock cycle and the AMD K7/K8 architecture (Athlon, Athlon XP, Athlon 64, Opteron, etc.) doing nine floating point operations each clock cycle. Floating point operations being the primary calculation used in gaming, where the Athlon shines. Simple numerical conversions as such can give a relative idea of performance. A 3.4GHz Pentium D in the case of your 840 EE (dual core also, but I'll get to that) is roughly equivical to an Athlon or Opteron running at about 2.3GHz. How'd I get that? Intel clock speed times 6 (floating point operations each clock cycle by Intel) divided by nine (floating point operations each clock cycle by AMD). It's rough, very basic, and shouldn't be taken too literal, but does explain why a significantly lower clocked Athlon can keep up, or even in a lot of cases, exceed the higher-clocked Intel. Now, on the dual core note, the 840 EE you're looking at has two physical processors inside it running at 3.4GHz each, and each of the processors therein running a logical processor capable of about 50% of the physical processor in multithreaded applications. It's unfair to compare that chip to an Opteron 150 (2.4GHz) because the Opteron is single core. A better comparison would be against an Opteron 180 which is a dual core Opteron with both cores running at 2.4GHz.
In the end, it depends on what you do, the 840 EE will probably have a lead in heavy multi-tasking and multithreaded applications due to its Hyper-Threading (I'd have to see benchmarks to confirm this though as the dual core Athlons have pretty much abolished all previous notions of Intel for multitasking, AMD for gaming, the AMD multicore processors are keeping up and even beating the Intels). The AMD however will more than likely excell in gaming performance.
The AMD also has its own little advantage to gaming, as Enterprise pointed out, the 3DNow! instruction extension which allows video card driver instructions priority access, which helps boost gaming a good bit.

PEOPLE GET PAST THE SPEED RATINGS....Speed comparisons mean nothing when comparing AMD vs Intel...It is the operations per cycle that Make AMD better for gaming...AMD does 9 and Intel does 6...This is why so many people get Intel over AMD because they lack the knowledge that AMD does 9 operations per cycle so they see higher GHZ and they think it is better when that is not always the case...

ok here we go

EE- $1000 -$1200
Opteron $775- $800

um well I think its obvious, AMD Winds lol, faster clock speed, good at gaming and its dual core

thanks for the help guys

but one last Q, what is the AMD equivalent of the mobo im using?
