AMD dual-core Opteron 100 series to be Socket 939

Charles Chou, Taipei; Jessie Shen, DigiTimes.com [Thursday 5 May 2005]

Advanced Micro Devices (AMD) plans to offer its dual-core Opteron 100 series using a 939-pin socket, according to sources at motherboard makers. The dual-core 100 series is scheduled to hit the market in the third quarter of this year.

AMD Taiwan declined to comment, saying the details of the product will be announced on the release date. Currently, AMD’s Opteron processors are all based on the 940-pin socket.

Motherboard makers quoted AMD’s roadmap as saying that the Opteron 152 will be the vendor’s last Opteron 100 series Socket 940 processor. All new dual-core Opteron 100 processors will be Socket 939.

AMD’s move is aimed to promote dual-core Opteron processors in the entry-level server and workstation segments, the makers commented. The new 100 series Opterons will allow vendors to offer lower cost Opteron systems, as Socket 939 motherboards widely support unbuffered DIMMs instead of registered DIMMs, the makers indicated.

In addition, most Socket 939 motherboards are built using four-layer PCB (printed circuit board) design instead of six layers, reducing the cost of the motherboard by about US$5, the makers added.

These processors already exist. I even have an official technical specification on them.

[afireinside]

Are you allowed to post anything about them or no?

[VVJ]

Maybe, some info I will post this evening.

this is entry level workstation no ecc ram so they are going to be cheap...

I give Xtremesystems.org a highly exclusive info about Socket939 Opteron processor :-)
So, currently AMD has three models of single-core Socket939 Opteron processor. These are Opteron 144 (1800MHz) and Opteron 148 (2200MHz) and Opteron 152 (2600MHz). All CPUs work at 1.350-1.400V of VCore, have 2x512KB of L2 cache size and based on Revision E4. My confidential source has confirmed that AMD Athlon FX-57 is just renamed an Opteron 152. Both CPU have absolutely equal technical characteristics.

So the Opty 152 has upwards unlocked multipliers?

[Vincentvega18]

what do you mean 2*512 kb L2? i thought that kind of thing was only for dual-core...........or did you just mean 1024?

[terrace215]

Actually, you can use ECC ram. Just like you can with an A64. I think you meant "unregistered" or "unbuffered" (same thing), vs. the registered DIMMs required with Socket 940.

(You can get all 4 combinations of memory: (registered vs unbuffered) x (ecc vs. non-ecc) although some of them are rarer than others.)

But the overall point is correct. Using unbuffered DIMMs will require fewer of them (2 per channel, vs up to 4 at slower speeds with reg mem, which is a negative, but these are low-end servers or workstations), but they'll have better latency, be cheaper, and the mobos will be cheaper and more plentiful.

This will allow OEMs to produce very cheap, low-end 1socket servers and workstations.

Huh? Opteron 152 runs at 2.6GHz. That is, FX-55 speed.

Did you mean a renamed Opteron 154?

[SHiRaKaWa]

the question is (Why?)

Why buy an opteron 148 for a 939 if we have a 3700+ or 4400+ for example?

[smegz]

That makes sense...if you look at the specs for the FX51 when it was released...they were the same as the Opteron 146. What about the new socket that was leaked out of Asia today...the M2 where will that fit in?

Socket M2 Story

BTW...no hard feelings on me razzing you about your source I just get a little carried away when things don't add up. If you got a man on the inside...then you my friend are an asset. It's nice for system builders like myself and most of the overclockers here to have a good technical source. Makes planning for the future a little easier and helps us flesh out our Christmas wishlists...if you know what I mean.

yeah i meant that unbuffured unregistered cheap ddr that is what i mean

I am confused the thread is seemingly about dual core and you said you had information on that yet it would seem you are talking about single core? Are you referring to single or dual core cpus if its dual then two things dont stack up firstly the jump to 2.6Ghz per core and secondly the cache is half what it should be

[mcnbns]

EXACTLY. I've been thinking about this all day and I can't think of a reason. I'm sure there's some info we're missing somewhere.

[saaya]

listen to what he said, those are dual core opterons for the socket 939

or did i misread something?

Saaya - I think everyone is confused because there seems to be an inconsistency. The thread title is "dual-core" and VVJ even refers to "2x512KB of L2 cache" but he says single-core. I'm hoping that's just a typo!

[saaya]

oh, i over read that...

2x512kb l2 cache... he prolly just means 1024kb l2 cache, its 2 blocks of 512kb... i dont tthink there are 512kb rev e4 chips, and all opterons have 1mb cache afaik... and the fx57 isnt dual core so yeah, hes probably talking about single core 939 opterons.

so the 939 opterons are single core? makes sence...

[saaya]

hmmmm or those are the entry dual core opterons?

939 = cheaper plattform, cheaper board and cheaper memory... and only 2 x 512kb l2 cache...

hmmmmm

[terrace215]

I think the point is that ALL Opteron 1xx parts (single and dual core) will be going to Socket 939, instead of 940.

So yes, the single cores become the equivalent of FX parts, with San Diego cores,

The reason for this has to do with the economics of the low-end (1-socket) server and workstation market, and also is related to DDR-400: Registered memory doesn't buy you more DIMMs at that speed, it's still 2 per channel, so there's really no point in forcing OEMs to use more expensive memory on a more expensive mobo.

[PicaXuu]

Opteron 152 is the last single core Opteron of the 1xx serie,
The new ones of the 1xx serie will be dual core and socket 939...

[linhvndiy]

Tyan have this mainboard S2865 base on NF4 pro , may be for that Opteron.

Hi guys! Just talked with my source and he confirmed that there's the 4th Opteron 154 clocked with 2800MHz. In my previous post there was two mistakes. An Opteron 154 is equal to the AMD Athlon FX-57 with the same clock frequency. Secondly, the AMD Opteron Socket-939 processor has 1024 KB of L2Size, of course not 2x512 KB. By the way, An Opteron 154 has a TDP more than 104W. That is all I have regarding the newest Opterons.

[saaya]

more than 104W? ...thats confusing me... a venice 2.2ghz only has around 40-50W... hmmm

thx a lot for the infos
