I want a K10 CPU!

[Gunlance]

Have they decided on what socket k10 is going to be? Or have I missed something along the way?

[Kingcarcas]

It would be really sad if Intel 45nm benchies are out before AMD 65nm K10 They said someone might leak 'um in April and now it's May 5th

Well they said is going to be AM2+, AM3 and Socket 1207, but they can change their minds anyway.

Fudzilla did leak something for the April fool's day.

Did you miss that or are looking for "real" benches?

We also expect the NDAs also to apply to the press, which means that first real-world Penryn benchmarks are likely to be published on July 15.

i cant believe im still seeing that god forsaken Socket AM2 on amd's future processors charts

I'm going to wait for AM2+ for my K10 and will use DDR2 memory. Don't need any of that DDR3 stuff yet.........

What a hobby..Always something new

Well they said is going to be AM2+, AM3 and Socket 1207, but they can change their minds anyway.

Let me see how compliceated this is.

AM2 = AMD Sockett for chips that support DDR2
AM2+ = AMD Sockett for chips that support DDR2, + being added like something they use to do before when they put words like Turbo or Plus. In this case + on the end stands for a DDR2 supporting chip plus HTT 3.0 support.

AM3 = AMD Sockett for chips that support DDR3
AM3+ = AMD Sockett for chips that support DDR3 but have some updated feature that older generation of chips that used the same sockett didnt have. New motherboards that still feature same physicall sockett to be distincty different from older motherboards have to carry a new sockett name to show that they support new generation of cpu's.

Sockett 1207 is the server equivalent of the the AMx socketts. AMD keeps server chips in same socketts so that upgrading dose not requier new motherboard, one selling point for the "Barcelona" is that it can be put into current motherboard.

CPU's being pin compatibe within chip generation (i.e AM2 and AM2+) you can put any AM2 supporting, be it a HTT1.0 or HTT3.0 supporting chip will fit in all motherboards, only there is little reason why anyone would put HTT1.0 chip in a new HTT3.0 supporting motherboard.

Now AMD has not changed anything when it comes to what they will call AM2 sockette or AM3 or what they will be for. Sure we heard rumours what such named socketts names might be but AMD didnt tell us them selfs so they never changed thier mind about anything.

So tell me whats so confusing or changing about AMD sockett naming scheme's.

Some of the future chips will only support HTT1.0 links so there is no reason why anyone would use a AM2+ motherboard for a HTT1.0 chip, especally since AM2 sockett motherboard will be cheaper reason why HTT1.0 features on cheapers chips.

Your missing his point. He's simply noting what sockets the Barcelona variants will support. The naming scheme has absolutely nothing to do with it; if anything, he is simply saying that the supported sockets might change, aka. no more AM2, only AM2+ and beyond.

[XS Janus]

Hmmm.... I can allready smell it!
And I hope it's not AMD screwing their new hope on the motherboard front that I smell.
That would be sad. I hope they have ALL the gremlins worked ou when they release them (maybe they should to a mobo soft launch next month, just to hype up). Hope they're focusing not just on K10 as a cpu...

compability with socket am2 will be one thing... the performance difference of one and the same cpu in a am2 vs. am2+ will be another and remains yet to be seen....

I thought i was clear. AM2 is same as AM2+ just no HTT3.0.

Low-end chips which would go into low end motherboards will not need as much as bandwidth as top end. Therefore there is no reasony why low end chips should have HTT3.0 links which would make them cost more.

AM2 will still exist, hence the reason why its still on roadmap, together with AM2+ because they are one and the same. So my point being until AMD sees that thier low end chips are being heavly crippled by lack of bandwidth they will keep the HTT1.0 links in which would continue the support for AM2 sockett. So really the naming scheme has alot to do with it because AM2 is made for mass market consumers not hardware the likes of hardware builders that have Sockett 1207.

Did i mention that AM2 and AM2+ are the same sockett?

[adamsleath]

will barcelona quad fit in am2 board?

[dinos22]

DROOL time to tone down on Intel CPU purchases i think

[adamsleath]

i spose am2+ if you dont already have an am2 boardy...??

[bloodbanger]

damned,just as i bit the bullet about my purchase this news-item appears...Again though choices

[_damien_]

I thought i was clear. AM2 is same as AM2+ just no HTT3.0.

AM2+ also supports split power planes and individual management of the memory channels. On AM2 boards they have to operate in lockstep, even though K10 features two independent address/command units.

I am not sure about that one, sounds like it has more to do with motherboards BIOS then the sockett it self. I guess it will be true but only because motherboards didnt have that feature as K8's dont have them, maybe if anyone makes a AM2 mobo that supports fully K10 they might have these features. But as i said before when K10 comes out AM2 mobo's will be budget mobo's for K8's and low end K10's so dont expect too much from them.

[Nil Einne]

So you guys think we can expect a (probably smallish) across the board AMD price cut in June for the A64s and Opties to coincide with the launch?

You could be right, but I trust the source, and based on my interpretation of AMD's tech docs I also think it makes sense.

The integrated memory controller (IMC) will get a few new features in the K10 core. When utilizing multiple memory modules, along with proper BIOS implementation and mainboard routing, the IMC can access memory in 64-bit channels (72-bit if you use ECC). This way it is possible to read and write data simultaneously, or improve efficiency for irregular access patterns which increasingly occur in a quad-core environment. This feature is available on AM2+ and F+ boards; on "old“ socket AM2 and F boards the usual 128-bit dual-channel mode is available.

http://www.dailytech.com/article.aspx?newsid=6918

While any K8 CPU has one single IMC, they are equipped with two sets of address and control pins to accommodate loading. So the IMC uses different pins to communicate with each channel, even though identical addresses/commands are sent (the channels are always accessed in parallel). So I find it likely that there is a connection between these pins and mobo traces that somehow prevents K10's two controllers from performing channel interleaving on current AM2 boards. The attached figure shows the pinout of current systems. Notice that there are two (redundant) copies of the following pins: address, bank, RAS, CAS, Write Enable. The presence of a second channel doesn't make it absolutely necessary to implement additional copies of the address and control pins (but OTOH pins used for data, strobes, clock signals and data masking are a different story). In addition, the fact that it'll only take a BIOS update to make AM2 boards forward compatible suggests that channel interleaving is *physically* impossible on AM2 boards. The pin-count of AM2+ remains the same, which leads me to believe that they use the "same pins", only with slightly different layout.

sAM2 - Supports all chips that have 940pins and use DDR2

sAM2+ - Supports all chips that have 950pins and use DDR2. It also supports split power planes(allows you to set different voltages, 1 setting for the cores, 1 for the IMC), and HT3.0. K10's will utilize these 2 extra features, K8's will not.

s1207 - supports all lga1207 chips

sG - supports all lga1207 chips, as well as the split power planes and HT3.0

http://www.theinquirer.net/default.aspx?article=39445
now, the inq seems to think AM2+ wasn't supposed to have HT3.0 but now will, but I always thought it would

also, they say the new server socket is called "g", instead of s1207+

either way, as has been known for quite some time now, the sockets are both forward and backward compatible. It's also thought that sAM3 chips will work in AM2/+ sockets because the memory controller supports both DDR2 and DDR3, but AM2/+ chips WON'T work in sAM3 since they don't have a DDR3 controller

[Radamanthys]

in deed the new's phenoms can't be pushed on the Am2 actual boards?

[informal]

in deed the new's phenoms can't be pushed on the Am2 actual boards?

FOr the 100th time already,the Phenom is backward compatible with AM2 and Socket F(1207) with a BIOS update!!!
Stop this questioning already.

[Avman]

yes they can - pay attention
