Do you guys know if the upcoming Intel CPU will work on current 965 boards + JUST a new bios, OR will there be the need for new board revision with some hardware changes on it to be compatible with Yorkfield??
:confused:
I know there is going to be a whole new chipset for it but it would be good if one could "pace" their upgrade somewhat.

Yorkfield is going to be 800FSB right? The only possible problem could be it's voltage requirement. But any decent core2 mobo has a very broad voltage scale, so it should work fine.
Meaning a bios upgrade at most, for the cpu's proper voltage to be detected etc.
Yorkfield will have a 1333MHz FSB. It will be go in boards with the upcoming Bearlake chipset which will be the replacement for 965 and 975X.
There will be at least four different Bearlake versions. Bearlake-X will have support for dual graphics cards and PCI Express 2.0.
I know the new "Bearlake" boards will be THE ones to have.Quote:

Thread revival;)
I just wonder what the difference between Kentsfield and Yorkfield will be?
I know it be 45 nm and probably clock greats:D
And that it will come with a 1333 fsb, and will be released in Q3 this year.
But what other difference is there?
Will it be native quad core?
Thanks :)
Yorkfield will feature the new Penryn instruction set. It will have 12MB of L2 cache.
Aside from that, we don't know much else. Yorkfield is meant for the upcoming Bearlake platform which will feature PCI Express 2.0 and a new southbridge (ICH9).
Yorkfield ES are already getting around, with new chipset, 1333MHz FSB and DDR3 samples.
It is? Where? Maybe Intel engineers and manufacturers have it. But I haven't seen it out in the wild.Quote:

Since its a modular design Intel may have beefed it up more its unknown . But Since Intel canceled spring IDF 07 Intel may very well be beefing it up. Or there is nothing new to report so they canceled IDF.
Cool!
Thanks Turtle1, keep on snooping :D

Now that you actually promised to stop posting Intel Yorkfield info in the K8l thread , you may perhaps post it here instead:)
Some question
1.You say DDR3 but will Yorkfield work in older ddr2 Core 2 dou/quad motherboards?
2.And about that 12mb cache. Wikipedia says this
so can you link to where you got that 12MIB Shared l2?Quote:

4.Any other news regarding Yorkfield please share:)
Well now that Intel has spoken and shown working Penryns . 12mb of shared is not likely. So it will be 2x6mb. Unless intel added a cross bar between the caches thats very unlikely.
But we do now know it is . HighK and metal gates.
Intel guidence says it will be 20%better performance using the same amount of drive current as the conroe at the same clock. Or you can lower the drive current and it will be more energy efficient. Since this is new tech and a brain new transitor it seems to behavy differantly than past transitors.
Intel also added 17% more transitors to the core logic. Improveing Gameing /Multimedi./Scientic computing . Also these new sse4 instructions its seems adds to the ability of intels refreshed compiler to read high level language and effect better thread parallelism .
It is said these new processor will be very O/C-able . As wellas very energy efficient.
Intel hasn't given out alot of info they seem to be holding back some.
It is rumored that these will be H/T but I find that hard to believe unless intel decided to add all 50 sse4 instructions. Penryn was suppose to recieve only 30 new SSE4 instructions. If penryn got all 50 instructions that means penryn also got a new compiler. It would than also have the ability to read high level language for better parrallelism. Which really doesn't mean much to us unless it has something to do with mitosis.
But the ability to read high level language with better parrallelism would be a big deal on servers. (look up Elbrus a company intel bought in 2004)
Oh, God, thanks Turtle1!
This all sounds great, can't wait :D

The bulk of SSE4's 50 or so instructions is comprised of new compiler vectorization primitives, which should make it easier for compilers to translate software written in high-level languages into effectively parallelized code and data structures. These new instructions encompass both integer and floating-point operations, and include provisions for dual- and quad-word multiplication, blending, and format conversions. SSE4 also has some related "media accelerator" functions that expand SSE's capabilities. Among them are four instructions that round floating-point values to integers and a floating-point dot product capability that should prove especially useful for graphics. Taken together, Intel expects these new instructions to help further the traditional promise of SSE as an accelerator for multimedia, 3D gaming, graphics, and scientific computing.
your 1) I could post links but I think we all know it will be 2x6mb.Quote:

Your 3 is unknown. Some instructions could be improvements of old instructions. Since the white paper has been out for a long time and intel has been actively working with programm writers it unknown. Some of those sse4 instructions work with the compiler which is manages the register
Turtle 1
Please show a link for 2x6mb if you know of any:)
And i ask again
Will yorkfield work in current Core 2 dou motherboards or will it require new ones?
The 2x6 mb cache are all over the web, you just google yorkfield.
I don't know the ans to your second question other than Intel said the five cpu's they demoed ran on un modded M/B . This question to me doesn't matter. These cpu's will run on a 1333 fsb its also been reported 1066 fsb. Anand tech article lays it out.
To me it just not an interest. As the only chipset I am interested in for this cpu is the X-38 Bearlake.

I didn't think intel would bring H/T out yet. They just don't need it. As penryn should keep the performance lead.
I heard Gigabyte DS3 and higher models will support them and FSB1333 with a BIOS upgrade. Also, I think the highend models from Asus will support them too (I mean the P965 based models)
So are you saying that you don't believe that bearlake X-38 won't attain A higher fsb than current 965 chipsets. Right now its possiable to get DDR3 @ 1333. By the time X38 is released there will be DDR 3 1666 or 1600 which ever. I would think Intel would be looking that far ahead with a High performance chipset. So I am thinking intel will have FSB of 400. quad pumped =1600. Running at DDR800 at 1:1. Thats just my thinking, of course 1333 will be the standard . But this chipset should have the option for DDR3 1600.Quote:

And btw K8 is still competitive in 4-way as for performance.The power usage is higher,but they are moving the K8 to 65nm so the perf/watt will be much better.
Look at post 21 I clearly never believed it. I have always stated and its in a lots of post the penryn would use only get 30sse4 instructions. The white paper in the Vector processing on nehalem(news section Thread) clearly shows penryn only getting 30 SSE4 instructions.Quote:

I to was in denial about the H/T being on penryn - But I thought well maybe AMDs K8l is a lot better than I thought and intel pulled some things ahead. I have always thought the penryn with HighK and metal gates would be enough to keep the performance lead based off nothing more than a shrink and the new transistors. Solely based of the increase clocks.. Intel is alking a 20 % clock increase for Penryn using the same power envelop.
That would 3.6 for the high end 2 core and as things stand right now but thats based off of a 3.0ghz I think before penryn arrives well see a 3.2+
So the 3.6 - 4.0 ghz penryn as being inline with what we heard . Do I believe a penryn will be faster at 3.6 than AMD @ 2.9 . In the mojotity of apps. yes I do. What does remain to be seen is how well these O/C if they are equal to conroe in over clocking ability. We are looking at 5.ghz O/C as common. For penryn. For myself a 4.75ghz on water is good enough. But other guys here will cranking these things up . Going to be alot of happy guys here. If penryn=conroein O/C-ability
If I were Intel I would have done things differantly. I would have left the L2cache at 4mbs. Used the saved transitors to double the L1 cache size. maybe that would have lowered the clock speeds I don't know. But increaseing L1 it seems to me would be a greater performance leap.
Turtle 1,you are talking about OCing the server CPUs man...Tell me what company in the likes of Sun will buy Yorkfields at slower speed bin and OC them?
Quadcore chips will work at their specd speeds,not the way you dream they will.
There will be some small number of enthusiast who will buy them to insert them in in appropriate mobos that allow OCing,but the server market doesn't work that way...
You need to exit that small world of yours where Yorkfield on air will clock to 5GHz.We don't know that.And if they will,power consumption will skyrocket due to higher voltage input and frequency...
And as for which will be faster,Barcelona or Penryn,let's wait for the benchmarks,shall we?Instead of talking bs about 4Ghz+ Penryns and HT that doesn't exist and vector units on Nehalem(which is a late 2008 product).
Yorkfields sound nice. Be cool to have. BUT a wolf running stock at between 3.6 -4.ghz. Running stable at 4.75 sable using water only because its better. Air should run here on these new chips. I DID SAY if penryn = Conroe in over clockability. NOW I KNOW thats a big if.But I must say my conclusions on this is based off of whats actually known.
Penryn AO chips run really well. Very GOOD sign . When you consider both the shrink and the new transitor .
What intel has said 20% higher clocks. At same power draw as Conroe-Maybe Thats a good sign this may indicate that if you use your present conroe M/B with same power envelope you would be running in the present Conroe power envelop A 3.6 penryn should slip right in to the socket and go.
So based off of what we do know and what we have seen. I exspect Penryn will be every bit as good as Intels says it is. The only thing not known is will this BABY spin the tires or will it actually get some bite and get up and go. If this thing is as GOOD at O/C as Conroe. You can forget about K8L. It really isn't known if K8L well O/C well we don't know. AMD mat figure we only need 2.4 ghz to handle conroe. Thats not known. So it is possiable.
But do i believe it NO way. I believe Intel but Not AMD. Look at what both companies have reported to the public in the last year.
Right now I believe Intel penryn will be better than they are reporting.
SO basicly I don't think K8L will be an O/C monster. I do believe Penryn will be an O/C monster.
Most honest people here would agree THAT based off of what we know.
What I believe is more crediabile based off of everthing we know right now.
Based Off the fact INTEL is Delivering.
AMD has nothing but talk trash for the lst 2 years. SHOWING nice pics of there K8L processsors. As if to be saying look here I got one right here in my hand . DO YOU SEE IT . ITS right in front of you.. We don't want to put it on a M/B tho and show benchmarks because we DON'T want to Put Intel to Shame.
I don't believe a word of it.
Rofl,turtle1,just rofl...
You guys really love to badmouth turtle a lot.
Is only because he sais things you guys wouldnt like to se or something else.
I mean the things he sais do sound VERY plausable and ar based on many truths as well as in line with "Intels new behaviour"
I my self am no experct at CPU design/talk but expect intel to folow through on this one as promissed, and judging by their confidence I guess they are not scared of showing of their sample right now.
The fact that Intels CPU might overclock way better than AMDs baby makes it THE choice for most of the members of XS.
As for the general public, if they perform within 10% percent of each other the will sell the same, just driven by fanboism of regular buyers
I do expect AMD to face up and show how it works in the real cause this up until now means very little and is pretty lame of them. More public friendly is allways nice - Intel realised that almost to late.
