Which is faster Athlon XP 2400+ or Sempron 2800+ 754?

[carlosd]

Which CPU will be faster at stock (no Ocing, I know that OCed the sempy will kill the Athlon XP) I cannot find any direct comparison between those CPUs?. Could you provide me some links. A semprom 2800+ socket A Vs. Semprom 2800+ S754 performance comparison would also be useful.

Sempron 754

take the sempron 3000+ Barton nf2 vs sempron 2800+ e6 palermo

 

[carlosd]

that goes to show how useless synthetic benchs( like sandra are(. Sandra says that Xp 2400+ is faster than A sempron 2800+, the most ridiculous says that an xp 2400+ is faster than an A64 3000+, please stop making those useless benchies.

 

[PingSpike]

The socket 754 should stomp all over the xp.

 

[Avalon]

The 2800+ Sempr0n should be a bit faster.

 

[maluckey]

There isn't going to be all that much difference mHz per mHz. I'd go for he cheapest bang for he buck since they (the CPU's and mobos) are both already obsolete.

That's rediculous. What are your parameters for calling something "obsolete?" If there's something faster? Well then, everything but the FX60 are obsolete then. Newest technology such as 64 bit, SLI and PCIe? Socket 754 has those. Still being made? Still has new products coming out? Socket 754 just saw the release of A64 Venice. What part of it is obsolete? AMD will keep making socket 754 CPUs until they start selling Semprons in a "newer" socket.

For the OP, I'd go for the socket 754 CPU. Even if they're the same speed and price, socket 754 has a great selection of motherboards while the "good" socket A enthusiast boards are disappearing from vendors. Also, socket 754 motherboards have some newer technology (unless you need to keep an AGP card). Finally, the Sempron 2800+ will run much cooler and thus with quieter fans than the Athlon XP.

It could be 'ridiculous' i suppose

While i agree with what you say i see no reason to buy s754 when s939 is so cheap now, and you certainly have a FAR better upgrade path with s939 (grab a 3000+ now, then a dual core further down the track (and possibly quite a bit further since atm it doesn't look like the move to a new socket will bring much in the way of speed increases...), and enjoy all the benefits of s754, plus dual channel memory and a real upgrade path...

 

[A554SS1N]

Hmm - the guys saying S754 are obsolete are obviously forgetting the point of this threads question - what's the cheapest? Moving to a basic S939 system would be far more expensive than what the OP is looking at price wise.

Right, now back to topic - the S754 2800+ Sempron is miles faster than the XP2400+ in virtually every situation, runs alot cooler, and uses much less power. All in all it would be a great buy - don't consider the XP2400+ under any circumstances as it's crap in comparison.

Oh teh noes, the spelling nazi. Ya got me there. Diarrhea is something else I have problems with (har har)... Actually I think I have a reasonable grasp of the English language, spelling included, for a second language.

What do you consider "so cheap?" Fry's has a Sempron 2800+ with ECS NFORCE3-A board for $80 (pretty much "guaranteed" overclock to 2GHz). You can also spec out an overclockable PCIe board/CPU deal at Newegg starting at about $125 that has a fighting chance to push the Sempron to 2.4GHz. What was the cheapest socket 939 CPU again?

Well said. Some won't miss another $50 or $100, but most now looking@sktA v. 754 would. 754 is a great budget gaming platform.

I picked up a used 2800+ and DFI 250GB for $115 shipped in FS/FT about 6 months back, added a zalman to NB, and it does 2.4ghz, is very quite, very cool running, and good bang for buck. Only compromise was having to use 2T with the 2x512 installed, that I had laying around.

Obsolete 754? I duobt you coul OC your CPU to 2.4GHz and keep it as cool as the semprom?. Can you use PCI-e with your socket A mobo?. 754 is not obsolete yet, it is an excellent budget machine, and the cheapest 939 CPUs is far more expensive while offering little performance advantage over palermo semprons. I have looking for some benchies and the Venice is in general 2-3% faster than the semprom at same clockspeed, with max difference o 15% in games given you have a very fast Graphics card. I can't wait for 939 semprons, what happened to them, aren' t them out yet?

I think the S939 Semprons are mainly being sold to OEM's at the moment, which is why they aren't being seen much - that and AMD probably wants to extend the life of S754 a little longer and make sure they've sold off all the S754 stuff first.

Yes I get your point, and yes, I can run my 2400+ at 2.4 or 2.5 Ghz all day long, and I don't know how much cooling matters except for volume. I'll play along and demonstrate my point. The below was done with air cooling with a 42 Cfm fan on an Alpha PAL 8045 cooler with the ambient temp at 70 f. This is NOT a loud setup.

Let's see some other numbers and we can compare CPU to CPU.

As far as PCI-e vs AGP....the AGP 6800 GS is a solid performer, though not in the same league as the 7800 line. If you are thinking abbout 7800 line, then why skimp on the mobo chipset and hinder your upgrade path? My point is that if you are going to go obsolete, then do so cheaply (used on Ebay or something). Otherwise, hold off until you can afford more.

Pity you didn't bother quoting or answering any of my other points A few extra bucks spent now on a s939 system would serve the OP well down the track (both in terms of performnace and an upgrade path), as well as performing considerably better (especially if you plan to overclock) now

 

[rogue1979]

Socket 939 and 754 motherboards are cheap. The cheapest socket 754 cpu is $65. The Sempron 2800+ ($75) has 256k L2 cache and overclocks like a banshee. The cheapest socket 939 is $164.

$100 dumped into a faster video card or more memory can go a long way. Until socket 939 Semprons become available, $100 is a significant reason to continue to buy socket 754.

depends on what you want i guess, sure you'll get an adequate (at stock like the OP says) system now with a sempron, but one that has little future upgrade potential (dual core ring any bells here? ).

A 939 system will blow it away at stock AND overclocked now, plus you'll have the opportunity to drop a dual core over the next few years that will eat any single core alive as apps and games increasingly all become multithreaded. It's short termism vs a long term decision i guess, and it really depends what you want to do with the machine, if it's just an office/file server, or a short term gaming rig you plan to replace when AM2 gets here, get the 754 for sure...

take the sempron 3000+ Barton nf2 vs sempron 2800+ e6 palermo

in far cry tom's has an athlon xp 3200+ barton (2200/200) hitting 134.3. but they have a sempron 300+ barton (2000/166) hitting 161.8. after that obvious error i don't think i trust this.

anyway, i may post the exact answer to this question a bit later, as i've got both processors around.

 

[rogue1979]

If you're not going for dual core, and simply want a reasonably fast system to game in, socket 939 is about 5% faster than socket 754 at the same speed.

So if you have a 7800 or a X1800XT it may utilize that 5%. But if you are using a video card that is slower then that, your money would be best spent on a faster video card using the $100 saved from runnning a socket 754. A Socket 754 Sempron at 2400MHz+ is not a slow cpu for gaming with a mid range video card, more than enough for all but the fastest.

 

[RobsTV]

Faster, as in based on artifical benchmarks, or real world feel?

Going from Socket 7 to Socket A was a huge noticable upgrade.
But going from Socket A to 939 Opteron 3GHz was nothing to scream about.
Sure, Opteron at 3GHz PC boots faster than mobile Barton @ 2100MHz.
I would never say anything close to the Opteron blows away socket A.
Games, 5% to 15% is not awesome speed upgrade. (skip CPU and upgrade video instead).
HDTV, I wouldn't call 5% improvement any reason to jump for joy.
Everyday stuff, like web browsing, email, etc. No difference.

Since I would now suggest most do NOT need to upgrade from Socket A to 939, you can guess how I feel about 754. The only thing socket 754 has going is price. Retail CPU w/HSF and motherboard combo's for $80. Socket 939 starter CPU/motherboard would cost at least 3 times as much. If your socket A dies, get a 754 to hold you over a few years, and hope the next generation will be better.

Basing this on current systems in use here, which are 6 Opterons (upgraded from Socket A), 2 socket A's still in use, and one cheap socket 754 combo. The Opteron upgrades from Socket A were the worst upgrade I've done in 10 years, simply because such a small bang for the buck compared to what was running.. I can understand though how many need to justify the money they spend, so they will see a huge performance increase in all they do when upgrading. I got out cheap, with $140 and $170 Opterons, and $55 refurb 939 motherboards, yet still feel shorted.

Slap a 7800 AGP card in a socket A system, and it will compete in gaming with nearly any socket 939 system, beating most (without 7800's)..

Good point!!

On the average, people with a 939 combo and a 6800 NU will lose out versus a well built Socket A and a 7800 series AGP card. PCI e is great, but the performance gap is large between vid card generations. It's unlikely that a faster mobo chipset can make that big of a difference.

 

[PingSpike]

Yeah, if you want to build a gaming rig these days the best advice is to sink all the cash you can into the video card.

If someone's considering socket 754 because he/she cannot afford or will not spend the money for socket 939 now, unlikely that they are gonna buy a dual core chip anytime soon.

How "long term" a decision was it for people to get Athlon 64 because of the "64 bit" capability... what was it, two years ago? WinXP64 is still half baked with drivers. Sure, there will always be something that takes advantage of a new technology, but when willl the programs that any given person uses start taking major advantage of that new technology? Software always lags behind hardware. Last I heard, only the Quake 4 patch makes decent use of dual cores. IIRC the COD2 patch doesn't quite live up to what the Q4 patch has shown. The day that most software "as it ships" gets a decent boost from dual core, I can imagine a future post by dug777 (among others) saying "OMG, socket 939 is like, waaaayyyy outdated and obsolete, and DDR is soooo yesterday's technology."

Not everyone cares to or can afford to pay extra now for a theoretical advantage that may or may not come to fruition (beyond a handful of examples) before their next upgrade cycle and not everyone likes to keep their motherboards forever. Especially in light of the spate of capacitor failures in recent history, I for one do not care that three years down the line my motherboard can still be upgraded with a faster CPU.

How many people who already own DFI LANPARTY boards "upgraded" to the EXPERT board when it came out? How many early adoptors of socket 939 got new boards just to take advantage of PCIe? How many bought a new motherboard because of more and "better" SATA ports? How many are going to get a new SLI board because the "obsolete" ones only really give 8 PCIe lanes per slot?

Not being dual core does not constitute being obsolete by a long shot. There is definately a place for socket 754 at a price point below the lowest socket 939 offering. If someone can easily afford to get socket 939, there is no doubt that it would be the better choice but blindly saying socket 939 is the only non-obsolete choice is doing a disservice to others because you're not taking into consideration their intended use for the computer, nor their budget. There is a time to recommend socket 939, but that time is not "all."

Yes yes, we all know that socket 939 is overall better. If being better is the only reason to buy something, then why aren't we all running Athlon FX60s? I know slower CPUs can be overclocked, but ones guaranteed at a faster clock to begin with (faster than many people's overclocks to begin with) can surely get a bit higher.

Mein Got, you sound just like people who blindly tell everyone that they must use a "good" video card in their build regardless of the fact that the machine is for a secretary who only needs to type up documents, or that it's for someone's grandmother who just wants to get online to exchange emails with the grandkids.

I'm gonna give you the tongue (don't get too excited now, ya hear) and create another thread dedicated to you.

A little while ago I moved from an Athlon XP 2400+ & 1GB PC2100 to a Sempron 64 2800+ & 512MB PC3200. Even with less RAM, the Sempron was most definitely faster. Factor in my 50% overclock, and it blows my old 2400+ out of the water.
