Athlon FX 55(SD core) Or X2 4800??

gline

Which is best to get the Athlon FX 55(SD core) Or X2 4800 these days?? As we all know that most programs/games dont support dual core so no major use for dual core now. I am going to be sticking it under mach 2, so i was thinking of the fx as unlocked multis is handy.

How do the 4800's preform though?? Anyone got them on vapo or mach 2 as i read their cap is 2.7-3.0ghz, not many getting it over this. Is that true??

Any thoughts on which to get? I will probably be using win xp so no real dual core support/enhancement until vista.

I've seen X2's at 3.5Ghz on Mach2's but I don't know if they can handle that constantly. Check XS for more info though.

I'd rather the X2 over the FX in general, but if it's for gaming you won't really see a difference over a 3500 or so.

thats what i meen, most if not all the apps/games are single threaded, any point in getting a 4800?

Azza

I heard the X2's are harder to overclock.

Do the FX chips not suffer from the cold boot issue that plagued users of phase coolers overclocking Athlon 64's?

Neither of those chips is worth the money. At most I would go with an Athlon 64 4000 or a X2 3800.

Here's a XS post with a 4600 X2 doing ~3.2 with a Vapochill LS.

<edit>And a 3.4Ghz X2 3800+ suicide shot </edit>

no the sd core fx's are fine on - temps.

The main reason i wanted to go for the 4800 is the 2meg cache, so maybe the 4400 also might be an option, its all about getting good oc's mate lol

WizZard

I went with the 4400 as it's cheaper and the cap is probably the same for OC'ing. Same reason as you, becasue of the larger cache.

Haven't had a chance to bench it yet. Might do it at the weekend.
I may get the new DFI Expert board too So I can watercool my chipset!

Whats dfi Expert??? post up ur benchies when you try ocing it.

WizZard

Will do. The Expert is the name for the new DFI Lanparty UT nF4 SLI-DR, and it is designed like the newer DFI Crossfire board, but, most crucially, it has 2 PCI slots width between the two x16 PCI-E slots allowing chipset watercooling!1! :D

cool, no news on the crossfire?? id really love to get that

The DFI Crossfire board is also slated for release at the end of September.

oh if only....lol
dobt wether anyone will see it then other than tech websites to do more benchs on it

Azza

The 2Meg cahce is not really going benefit you is it. 1 Meg is on the second core. So unless your multitasking or got a dual core support application it won't benefit you. The dual cores perform the same as in single core applications as a single core at the same speed if I'm not mistaken.

yeh i was just lookingfor ppls opinions. So you'd recommend a single based core cpu?? FX??

My 4400+ @2400'ish (using the provided air cooler!)& standard x800xt scores 6087 in 3dmark05 about 200 up on my old 3800+ Winchester.

Unless you're planning on running BOINC or DIVX encodes at the same time as gaming you're probably better off with the FX....

Exactly. Unless you multitask a lot, you won't see a difference in single/dual core for now.

i think i am gonna try get the fx 57, selling all my old components off soon, fx 51 , mobo, ram etc. so i should be able to get the fx57... getting a mate to ship it in from the US

WizZard

Don't get the FX-57, get an FX-55. No real difference. The FX-57 doesn't clock to highly and is easily beaten by the FX-55's (Claw/San Diego).

No point spending way more than you need to...

ive seen some 57's clocking to very good speeds. Just the heat is more of an issue, no prob for the mach 2 though

DFI Crossfire board for sale here

Why not get some new Patriot DDR700 RAM for it too

hmm im really out of touch with all this ?? that ram any good, i will be buying parts on 30th of this month, so its looking like crossfire so. Can any normal x850XTPE be used with the crossfire edition of the card? I suppose the crossfire x850's wont be out for ages yeh?

WizZard

Well, AFAIK ATI are pre-shipping cards so that when they launch Crossfire they wil be immediately available, but I haven't seen any stockist mention anything yet.
ATI's dates are end of Sept for first Crossfire cards (DFI intend to coincide with this) based on current chipsets, and the R520's are coming out at the end of October onwards, in the order Mid, High, Low end cards. Basically any card bought now is supposed to work with it's Crossfire counterpart when they are launched.

Patriot only launched the RAM the other day, and nobody has reviewed it yet
It can only run at 2T and with loose (think DDR2) timings, but has HUGE bandwidth.

i dont need HUGH bandwidth, LOL. I was going to get the ram u have as i heard it can be hard to pair ram with dfi's, so at least that is guarenteed to work, ram is always a hard decision. If crossfire isnt available wen i buy, im going for 2 x 7800 Gt's

gline

i want ram that can do 500+ @ 2-2-2-5

whats the best? Probably bh5 would be the stuff to do that, yeh?

WizZard

I have some OCZ Gold PC4000 VX sitting around waiting to be benched so I'll tell you what that can do. Supposedly 2-2-2 @ DDR500.
The only RAM to beat it is the Mushkin Redline XP4000 (another DFI special) which does the same 2-2-2 timings @ DDR500
Both of these take at least 3.3v to run, so you'll need a serious PSU.

I'll tell you what my results are when I bench them. My RAM is EOL now so it's really hard to find. It's more for bandwidth than tight timings though. It does have the tightest timings at DDR625 speeds than any other RAM though.

An SD (or any E) core chip will struggle to get more than 270FSB (with a good multi) though, which is why OCZ pulled my RAM. Dunno what results are like on PC though, or if they can go higher with it?

il be looking at an ocz powerstream 600w+ or something similar. Hmm let me kno how the VX goes as id be interested in that. I mite search for some bh5 on ebay or something also

Mythago

Might be worth looking at this before going with crossfire:
Serious Crossfire Limitation

WizZard

Interesting yet scary!

AS they've pointed out it's unreleased so we'll have to see if it is a limitation. Remember SLi had horrific problems with hi-res widescreen monitors until the 77.7x drivers!
