Athlon 3800+ 2.0 vs P4 3.0?

July 30, 2009 at 12:16:48
Specs: Windows XP
Hi, I'm looking at two reconditioned PC's. One is a Pentium 4, 3.0 GHz (DC5000 series), and the other states "AMD Athlon 64 3800+ 64 bit processor with AMD64 Technology, Operates at 2.00 GHz, 2 x 512KB L2 cache, 2000 MHz system bus". I have a friend saying the 3.0 will always beat a 2.0. The P4 3.0 has a small HD (40GB), and only 512 MB RAM, while the Athlon 2.0 has 2 GB RAM and a 320 GB HD. The Athlon is about $40 more than the P4. If I got the P4, I would want to expand the RAM to at least 1 GB, and put in a somewhat larger HD. Since the Athlon is 64 bit, and the P4, 32 bit, would the Athlon has any advantage? The P4 will be running XP Pro I believe, and the Athlon XP MCE 2005. Thanks much.

Your friend needs to do his homework; the AMD will tromp all over the Intel in this comparison.

The Athlon 64 3800+ runs at 2.4ghz not 2ghz, unless you are talking about the Athlon 64 X2 3800+.

I think your friend isn't up to date on modern day processors. Ghz speed doesn't automaticly = performance anymore like it used to. Back before chip architectures became a lot more efficient than they are today, processors in years past needed a lot of speed to perform well, but that's not the case anymore. Now you can have a core 2 Duo E63xx for example running at 1.8ghz that can beat a Pentium D 965 EE running at 3.7ghz in just about every single benchmark. That's a whopping 1900mhz diff that the Pentium D 965 EE has over the Core 2 Duo E63xx. So as you can see ghz now of days doesn't mean nearly as much as it used to, it's all about mostly how good the architecture is on the chip itself now.

Thank you, thank you.

I'd like to thank Mom and Dad, jam, johnoh, Justin, The Academy, producers, directors, Chrysler Corporation, dumbass neighbors, people who won't read, my ISP, E&J, Coors, and Tek-Tips style ratings for this award.

For about 3 years, I came here only to read. I started posting to give a bit of help and to step on others who gave answers and help that were so absurd they made me wanna cry; so I'd like to especially thank the "Techs" who jump in here and give answers without portfolio.

Hi Everybody,

Thanks very much for the info.

"The Athlon 64 3800+ runs at 2.4ghz not 2ghz, unless you are talking about the Athlon 64 X2 3800+."

- which to my untrained eyes looks like the same processor, but at 2.4 instead of 2.0. There's no website for the P4, it's at a local PC repair shop, they have a bunch of the DC5000's.

I want XP over Vista, as I have older versions of many programs that I hear will not work on Vista, and can't afford to upgrade right now.

So even at 2.0, will still be much better than P4 at 3.0 I read here. That was my gut feeling. I want to put a digital TV card in the PC I get, so I want the one that's fastest to run it.

Thanks much.

PS I'll edit to remove those two links after I get input on the 2.4 vs 2.0 issue so it doesn't look like spam.

I just called up the store and asked if the one I was interested in is actually an X2, and he said No, and the web page would state if it was. I asked why the speed difference and he said something about how the sockets are arranged.

You don't need a high end machine to just watch tv. My bedroom tv is a pc with an old Athlon XP2400+/512Mb PC133/W2K, cheapo Radeon 9600SE, tv tuner card, and 19" CRT. It also records well.

Editing the recorded video is another deal though. That's where the AMD machine you're looking at will thrash a P4 or my bedroom machine.

Well the guy you called either has no idea what he is talking about or the web page itself is wrong. there is no such thing as a Socket 939 Athlon 64 3800+ Single core running at 2ghz. Only the Socket 939 Athlon 64 X2 3800+ Dual Core runs at 2ghz.

"From AMD:

Thanks, but that info is a bit over my head. What I'm assuming here, and again, thank you everyone for your help (I'll have to come back and give you all good votes on the answers).

What I'm getting is that the 3800+ 2.0G in question HAS to be really 2.4, or else it is actually an 3800+ X2, which the web page doesn't specify.

I take it X2 means "dual core" and as such, an X2 at 2.0 will be more efficient (in general) than the "plain old" 3800+ at 2.4? And either one of these 3800+ will, again, in general. kick the butt of a Pentium P4?

I want to order tomorrow, so unless I'm told otherwise, I'll order the XP system with the Ahtlon 3800+ "2.0", 2X RAM and bigger HD for $15 more than the Vista system.

One other concern which I know is off topic in a way, but may help my buying decision while I'm here, is I was told that Vista (Home Premium in this case) will not run my somewhat dated software, such a Word 2000. Excel 2000 (Office Suite 2000 Business Pro I think), as well as Photoshop 6. I was told I'd be better staying with XP.

Thanks much again.

Yes you are correct the 'X2' on the Athlon 64 means Dual Core and the only socket 939 processor that ran at 2gz was the Athlon 64 X2 3800+.

Well it depends, the Pentuim 4 56x 66x will run neck and neck with a Socket 939 Athlon 64 3800+ single core, but the Pentuim 4 56x or 66x has the slight edge when it comes to multitasking due to it's Hyperthreading when enabled. But the Socket 939 Athlon 64 X2 3800+ will beat any Pentium 4 with Hyperthreading enabled hands down in multitasking because it has a second real core that share a seperate workload from the other core. Unlike the Pentium 4 with Hyperthreading where it's more of a virtual 2nd core instead of a real second core that uses the same core to share the workload.

Athlon 64 system is def the better system over the Pentuim 4 system offerd.

Office 2000 can be installed on Vista except for Outlook.
Photshop 6 you may have trouble with.

Thanks much everyone. I ordered the 3800+ 2.0, as it has XP. If the processor isn't dual core, I'm sure I'll survive, but all the other features seem great, and either way seems good for the price. I also removed the two store links so that other post of mine in this thread doesn't look like spam. Again, thank you everyone.
