What (if any) performance gains are there with Athlon64 w/o 64bit OS

[ttown]

Comparing an Athlon at speed X, and Athlon64 at speed X, are there any noticable differences between the 2 when running a 32bit OS (specifically win2k server)?

?

Is there a difference in benchmarks yes, a slight one one.

For real world applications though, an AthlonXP at speed X will run about the same as an Athlon64 at speed X.

Then again, the same can be said for an Athlon64 3400+ versus a 3500+. The actual real world difference is nearly imperceptible, it's more just knowing you've got a faster processor and that oh-so-fun feeling that goes along with it.

What? Are you kidding? At equal speeds, the AMD64 will run much better than the corresponding Athlon XP. The onchip memory controller alone greatly increases performance. I would imagine you get at least 10% difference in performance at equal clock sppeds

Good comparison chart

It's probably closer to 30% in games

LOL, yeah I was trying to be conservative and he asked about Windows 2000Server. It will be faster in every instance at equal clock speed with some differences profound like you said.

a guy with a 2500 amd64 and the exact same videocard (as well as same amount of ram and I'm using a 3 year old harddrive) got the same score as i did with xp-m@2500 on pcmark04, it s just the memory bandwith improvement that helps with some tasks (he thrashed me in winrar but i generally barely beat him in the rest)

Well I am glad you used real world test like pcmark04!!! 😕

In games he should beat you....In encoding it may be similar...In winrar he should crush you....In any app that is bandwidth intensive or latency sensitive he should beat you...

Please post some real test to verify your accounts.....


That is an AMD 64 (non sempron) chips Oc'd to 2500mhz??? Not a pr rating right???



Go to toms and type in a comparison of a 3200+ Barton 2.2ghz ddr400 512kb of l2 cache and a 3500+ winchester 2.2ghz with 512kb of cache....


It isn't even close in some test as mentioned, above...

You either are not comparing apples and apples (system difference effecting much more), dont know WTF you are doing, or lying...could be any of the 3....

Both cpus while ocing will scale pretty similarly and fairly linear so 2.5ghz chips should hold same lines....

Is benchmarks really what you use your computer for? Compare real world applications. For example, there's a big difference in Half Life 2.

At equals clocks speeds, an Athlon 64 is at least 20% faster than an Athlon XP.
