Socket 939 vs 754

[Addikt]

Well, I was looking at processors and I found that I can pick up an older Newcastle 3400+ clocked at 2.4 GHz that actually outperforms the newer Winchester one using the 90nm. Actually, sorry it's the 3200+ NC that outperforms the Winch and the 3400+ NC performs close to the 3500+ Winchester.

The only problem with the 3400+ is that it is only available on the older 754 socket. Are there any huge performance problems with this. I remember waiting to see the impact of 939, I thought it was gonna be huge with a dual channel memory controller but it ended up not really doing much.

Just wondering if I should take advantage of the low price and high performance of the chip, but unsure of what I am giving up by not using the 939 socket aside from upgrading, I don't care about upgradablity.


EDIT: The numbers are given like this 2200/250 for the 3500+ and 2400/200 for the 3400+ what does this second number signify? FSB?

you should get socket 939 since upgrading is gonna be tough with socket 754. The dual channel memory doesnt have alot of affect on the a64's like it did on the p4's since the a64's have a built in memory controller on the processor. i suggest you get socket 939 unless u dont plan on upgrading at like all i heard agp8x is dying very fast and should be done soon so i heard though i doubt it still.

winchester core isnt much better than the newcastle except the winchester core oc's better just like the venice core is going to.

Upgrading isn't really a concern. From what I have seen in benches the higher clocked 3400+ even out-performs the 3500+ most of the time.

Also it's clocked at 2400/200 as opposed to 2200/250, what does the second number signify? Is this the FSB speed?

w00t he already said he doesn't care about upgradability....
addikt.. i was thinkin about the same thing as you did.... but i plan to see how the prices will act upon the arrival of dualcore... so im waiting more...
i dont see why not about saving money since u dont care about upgradability... but i'm pretty sure u will get better OC results with 3200(939) thatn 3400 tho... but who knows..

 

[imported_Kensai]

Actually, you can get a 3400+ S939. They're quite rare though and they're underperformers.

There is no "FSB"

3400+ S754 = 2.4ghz 512K cache
3500+ S939 = 2.2ghz 512K cache

Ok, yeah I don't think I want an underperformer...I am a bang for the buck guy. I don't know about OCing the 3200...I am pretty sure you could OC the 3200 though since is uses the 90nm process and would be much cooler. The other option is waiting for Venice, but it will be a while before the extra coding commands are adopted.

Also, it's really bugging me what this second number means... =/

Host Clock (FSB) x Multi = Core Speed



200 x 11= 2200 Clawhammer L2 1mb
200 x 12= 2400 Newcastle L2 512k


A64 3400+

If you decide on this go for the faster clocked a64 ... i would if i had to do it again...

 

[Addikt]

There is an FSB, they just choose to call it a "HyperTransport" but it is very much a FSB. I know the speeds and the amount of memory I just don't know what the 200 vs the 250 refers to.

3400+ Newcastle @ 2400/200 (754)
3500+ Winchester @ 2200/250 (939)

What does that damn second number mean?

Also the other option is to wait longer and try to pick up a 3800+ for less, but I don't think it's going down to the price I want it at any time soon...

Link us

 

[Addikt]

Yeah, sorry man I saw the specs and the extra 512K of cache actually slows that chip down...

Anyways, so does the newer Winchester have a 250MHz pipelined FSB and a lower multiplier?

I mean it's 2200 but with a faster FSB that would mean a lower multiplier at like 9 or so...

EDIT: If you want a link it's from THG, not the most reliable source but it shows all the clock speed and what I assume to be the FSB speeds...

damn read

Host clock x Multi = CORE SPEED damnit

 

[XBoxLPU]

THERE IS NO FSB

Cache doesn't slow it down

right on


250 that would make your ram run at ddr500]

I did read it. Host Clock = Bus? Because every source I have found thus far says "bus speed time a multiplier factor."

 

[Lysawy]

looks like a misprint at Thg


or they were running ddr500 with a lower multi.....


AMD will adopt new ddr standard but which one i have no idea.....

 

[Addikt]

Well what about buying a 3200+ winchester and OCing it to 2.4 GHz...would the be difficult to do? I mean it does have smaller process and would run cooler, think I could get it to 2.4 running a stock fan with no extra cooling needed?

 

[l Xes l]

i've seen 2.4 Ghz w/ stock HSU many times...

there are pci-e nforce 4 754 boards now, so upgrading a video card to later pci-e is a moot issue. IF you want a better bang for the buck get 754, but when it comes time to upgrade the cpu, you'll be forced into a new mobo.

The 250 refers to the HTT running at 5X (simulated FSB 1000MHz), whereas the S754 chips only run HTT @ 4X (simulatedFSB 800MHz). Even though there really isn't an actual FSB as its integreated into the CPU.
This is not a big difference though, as it can't really use the extra bandwidth.

Edit: I guess my math is off. I don't why it say 250.

 

[XBoxLPU]

I just think Tom's is smoking crack

250 x 5 = 1250
