64 Bit Processors Are Slower Than 64 Bit Ones???

I have just purchased a AMD Athlon x2 4400 CPU much to the disgust of the I.T. Manager in the office.

He warned me not to get a 64 bit cpu as they are currently slower than 32 bit cpu's. When I asked him why, he said that so many programs that I use such as Macromedia's DW MX 2004, FW MX2004, etc are 32 bit applications. If I would run the application on a 64 bit cpu, then something called a 32 bit emulator would kick in so that the 64 bit cpu could run the programs. The emulator would slow down the pc a lot.

But in the long-term (1 to 2 years), my cpu would come in handy.

Is any of the above true?

Have I just gone and spent my savings on a cpu that is actually going to be slower than my current Intel 2.2gHz 32 bit cpu?
 
When the processor arrives, power it up and let that guy see how fast the baby is and make him cry 😛

The 64 bit support is only an added extension (includes the needed registers of course), but it would run 32 bit applications flawlessly. But remember this thing, if it runs slower than the intel 32 bit CPUs, then why would many people here recommends buying off the AMD 64 CPUs? Duhhhh..
 
your manager is probably talking about the Intel Itanium processors, they are 64bit native and do not support x86 code, MS develops a separate OS for that processor, and yes he is correct that an emulator is used to run 32bit apps, but this is only for this processor ONLY.

Your processor is an x86 processor, and is 32bit native with 64bit extensions, the 64bit extensions allow the processor?s execution units/registors to be able to execute/run 64bit code.

So you will have no problem running 32bit current day software, and when 64bit software becomes mainstream you will have no problems running 64bit code either.

FYI Intel Itanium processors are specifically designed for large server farms/clusters as a PDC, which has no relevance or need for client and home user use.
 
Thanx guys. I will print all of your comments and put them on his desk.

I will install Windows XP 64 Bit edition and Windows XP Pro.

Do most programs work with Windows XP 64 Bit edition?

Programs shouldn't be a problem, but I have heard mention of 1 or 2 apps having issues with it. IIRC, the one App I've heard about was XSI SoftImage which was having an issue where it wouldn't accept the Serial code on Win64.

The main issues with win 64 have to do with Hardware Driver avaiilability. Before deciding on it you would be wise to doublecheck the availability of Drivers for your Hardware you'll be using.

Great! Let us know of his response! Also, make sure that he really understands that there is zero emulation going on with 64-bit capable x86 CPUs like AMD's Opteron/Athlon64/Sempron and Intel's Pentium4/Xeon/Celeron.

This should really be mandatory knowledge for an IT tech...
 
My 7800GTX (BFG OC) and 4400+ Get right around 8000 in 3mark05 (which is a 32bit program) and I am using XP 64bit so 😛 to your I.T. guy. I bet I would get even better Performance if I was actually running Windows XP Pro because while no emulation is needed in a A64 to run 32bit code an emulator (in this case WoW32) is needed on a 64bit O/S to run 32bit code.
 
[That "IT Manager" should look for a new job. Maybe janitor or something... ]

Hah, that's for sure. Take this guy's job away from him. He doesn't deserve it.
 
IT Manager? How pathetic. Tell him to research before spewing sh*t out of his mouth. Then again, I know more about computers (an accountant) than our IS manager. Go figure.
 
Depends what your comparing. The A64's are great running 32bit os and I assume 64bit os. But I've seen a Far Cry comparison, everthing is identical (don't remember the system, FX-55?) except for the operating system (windows XP vs XP 64) and Far Cry (again 32 vs 64). It turned out that the 64 bit version ran a bit slower, nothing significant but it was slower.

...anyways I just thought I'd add another perspective.

That was probably back before there were any decent drivers for XP-64bit.
 
He's pretty decent as regards networks and so forth, but I realised he was talking trash when he told me that the A64 was slower than a A32 CPU. I am a marketing guy (who is also learning to program).

Why would companies like AMD & Intel launch a new product if they knew would be useless in the short-term? The research, manufacturing & marketing costs alone would be in the hundreds of millions of dollars. No company makes that kind of mistake, never mind two of the biggest tech companies on Earth!

That is why I knew he was talking whack. I just wanted to get feedback from you guys so that I could show him.

He is so stubborn though. He came into the office today and I showed him all your comments. He looked at them and said that you and I are wrong and that he's right.

He is Greek-Cypriot (I am half Greek-Cypriot also), and they are a very stubborn race of people. I could tell he knew he was wrong, but he wouldn't admit it.

When I put it together, I'll bring it into the office. The proof will be evidence enough.

Just show him a A64 2.2GHz vs AXP 2.2GHz benchmark to pwn him.
 

Considering Intel is using the same 64 bit extensions (that make the Athlon 64 a 64 bit processor) in the 6xx and 8xx series P4 and some of their Celerons I would be interested in what processor this ?IT manager? would recommend.

VIA C3!
 
Basically almost all 32bit app have some problem.. im using w2k3 64bit server.. a lot of stuff won't run correctly... i'm just waiting to host a bunch of 32 bit vm in my 64bit server... more room to grow with more vm to run..
