How does the AMD Athlon X2 7750 hold up?

My friend has a 4800+ X2 on an Asus M2N-E motherboard, but it seems to be a little slow for a modern computer. The phenoms are a little too expensive, and he'll rarely use four cores. I was thinking about getting him an AMD 7750 to put in it. Would he see a noticeable speed increase? Would it be better to go with a 6000+ X2 3.1Ghz? He refuses to overclock, but I'm still trying to convince him. So, is the 7750 significantly better than the 4800+?

Yes it is and its worth it for the price if you are buying new. I would not however spend it on the upgrade you speak of. The difference is not going to be that great. Save his money and get a new chip next winter.

So, the 7750 is a great chip, but it's not that much better than the 4800+?

I own both a Brisbane X2 5000BE and the Kuma X2 7750BE. The 7750 is the better processor, but not by a large extent. I personally wouldn't replace that X2 4800 with a new 7750, price/performance wise you won't get your moneys worth. If an extra 15% performance is worth $80 to you, than go for it. Might I also note the 7750 comes with a garbage cooler and runs much hotter than any Brisbane I've seen while consuming more power.

I would get him an X3 or X4, but I don't think he'd use it fully. Would he use the extra one or two cores when he's just doing office tasks, web browsing and light gaming. I thought a X2 at 3Ghz was faster at those tasks than a X4 at 2.5Ghz. Is this wrong?

This is my rule of thumb over the last few years. I have stepped up from 939-am2-am2+. The differences have been minimal at best. AMD dont forget did not give us much. Intel has been ruling the roost for a few years. Now with the P2 @ 3.0 we finally have a wonderfull, OCable upgrade with a VERY good price vs performance ratio. Unless you are going for a new deneb there is very little you can do with AMD platforms that is viable for the money you put out. Saving your money or building an AM2+ system with the new core is just about the only thing you can do. Everything else yeilds very poor results atm. We are still waiting for 2 and 3 core versions to appear though so things should change over the next few monthes.

X2 is a waste anymore with the X3 and X4's out there. My X3 at 3Ghz is 40% faster then a 6400+ and only costs 30 dollars more then a 7750


Too generic. Depends on your budget and the application.
If this dude only has £70 to blow and doesnt use anything multithreaded then on an AMD platform the 7750 is a godsend.

The applications being used are Microsoft Office, Firefox, itunes, and battlefield 2. The 4800 can do all of this fine, but it just seems sort of sluggish compared to modern computers. Since everything works with the 4800, the budget really doesn't exceed $100. I just don't want him to spend $100 and not notice a difference. Is there going to be a noticable difference going to a 7750 or X3 8450/8650? I don't like the idea of the X3, because they're only clocked at 2.1/2.3Ghz.

Well, considering the budget the x2 makes the most sense. Whether it is worth it to you/ him will be your decision. Didn't mention if the board is am2+, or I didn't catch it. If so are you going to pair some 1066 mhz ram? Otherwise you prolly won't see this proc. true potential. Also will you be overclocking?
I'm pretty sure the Phenom 7750 can attain speeds of 3.0 ghz, prolly even a bit higher. But then you would need to add the expense of a new cooler.

So all things considered, if you just want to drop in a new proc and go, then the 3.1 ghz X2 is yoiur best bet. However for 90 you can get a 3.2 ghz X2 6400 with 2mb of cache vs the 1 mb for the other.

I'd say go for the 6400+ for the extra speed and cache, and that should give a decent boost.

The board (Asus M2N-E) is AM2, not AM2+. He will probably not overclock it at all. He's got 2GB of 800Mhz of RAM (OCZ gold, I think). He won't be getting 1066Mhz RAM or straying from the stock cooler. Does anybody else agree with buzznut?

Also, I thought the 6000 3.1Ghz was newer and better than the 6400. Is the 6400 really better?

I have a Nforce chipset socket 939 board with a single core Athlon 64 3000.

The best chip you can still find "new" for it are the dual core Opterons. If you can find one there fairly cheap now.

But it might not be as good a value as a new motherboard and CPU.

As for AM2+ boards

I personally don't think the 7750 bench marks look all that hot.

There are other X2's that beat it.

Why spend money to be in last place still?

My single core 1.8ghz runs Ubuntu like a champ.

I have a new PC for Vista.

Nope.
I did it. I waste my 79,- on 7750BE, oc to 3.1 on GIGABYTE GA-MA78GM-S2HP AM2+/AM2 AMD 780G and I cannot see any pros to compare my old 4400. But hey, W7 index jump up +0.7point jej.
Sorry, but it is a Waste imho. :o

If your not going to OC, the only upgrade to even consider is the 6000+. If you were OCing, the 7750 is very tempting.

You upgraded 700Mhz, more cache, and better technology? Do you really not see any difference?

Do you mean the 6000+ 3.1Ghz? Would the 6400+ also be a good upgrade? Is the 7750 not worth it without OCing? If he were to OC, would the 7750 be the best processor?

How big of difference does the 90nm vs 65nm make in performance?

You had me at BF2.

BF2 needs >2.6 to run right (assuming you are playing multiplayer, and are at the mercy of the speed of others' computers). The closer you get to 3 the better. I had a 2.5 GHz X2, (4200 OC'd) and I suffered constant lag that I didn't even realize I had. With the same videocard, I then went to a 3.2 GHz (OC'd) Intel 2180 and went from being a middle of the pack player to a top of the pack player (existence of lag determines whether or not you come in first or second place in a shootout with someone else). I think BF2 only uses 1 core (but 2 cores lets it run better), and certainly not 4.

FYI, BF2 (and Office, Firefox, etc.) also benefits greatly from >2 GB RAM. Going to 4 from 2 (actually 3.2 GB with XP) also made a big difference in smoothness.

Bottom line: go for the 6000 if BF2 performance is in any way important to you (him).

Yes,yes i can see few maybes here and there, but overall
nothing impressive or interesting at least. Running benchmark on current mobo is cool, but running bit unstable windows 32bit home ed. + office is different cup of tee. You need a bigger kick to see clearly some diff. in real working progress. This baby is using Hyper Transport 3600mhz but my mobo has FSB 2600mhz.
Could be this A reason why it not perform so well on my setup?

i got a 7750 to replace my buggy phenom @ 2.2ghz, doubled my fps on the 8800gt in all games, got it in my new rig with a gtx 280 and my cpu score on 3dmark vantage was 27k for the cpu alone.

Overclocked the 7750 will a a noticeable upgrade to his 4800. At stock speeds not so much. If he really doesn't want to overclock then a 6000+ should be just right. The 6400 runs significantly hotter.

i thought i would let you know i hav the asus m2ne and i bought the AMD athlon x2 2.7ghz blac edition and they are not compatible just because the board is socket am2 and the processor s socket am2+ when i looked at the mobo specs its says it supports athlon x2 but it has to be am2 not am2+ they dont tell you that so i have a good processor sitting here on my desk collecting dust. just thought i would let you know.
