Kuma Manifests into Athlon X2 7550, 7750
Industry sources reveal that AMD would be branding its Kuma dual-core processor as Athlon X2 7000 series. These processors are aimed to compete with Intel's Core 2 Duo E7000 series processors. Kuma continues to use the 65nm SOI fabrication process. The core sports 512 KB L2 cache per core, and a shared 2 MB L3 cache. Surprisingly, despite having sub-3.00 GHz clock speeds, the processors have rated TDP of 95W.
These processors use a broader 3600 MT/s HyperTransport interface, and feature DDR2 memory controllers that support the PC2-8500 (1066 MHz) standard. As for the models, the Athlon X2 7550 has a clock speed of 2.50 GHz, and an FSB multiplier of 12.5x. The Athlon X2 7750 comes with the clock speed of 2.70 GHz, and a FSB multiplier of 13.5x. Both processors are expected to be out by Q1 2009.
As for its 45nm successor, there are early indications that it would be succeeded by the Phenom X2 10000 series processors. Depending on the clock speeds, they would be branded as 10x00, with "x" deciding the model number. These would support PC3-10600 (DDR3-1333) memory and have lower TDP of 65W.

I would like to point out, however, that most of the reports I've seen on the Phenom X2 (successor to these chips?) note a 45W TDP, versus the 65W mentioned in this article. Sources anyone?
Im 99% positive that all the CPU's that come out are ether true dual , triple or quads.
It would be a complete waste of resources to make a quad core and sell it as a dual core?
Hello that 2x2 sticky thing is Intel. 4 individual cores with shared L3 cache is AMD. Tri is one core disabled and same with dual, 2 cores disabled. I don't think they would have spent anymore time in coming up with a true dual-core design based on a broken design. Its just they try to make max use of broken ones while their engineers hopefully breaking their head to come out with a smash hit design.
The first batches were Conroes, and then they were Allendales.
*rolls eyes* omg ill have to explain to you what i mean, since you did not get it the first time, when i mean 2x2 i mean it has 2cores above, and also 2 cores below, regardless if its AMD or Intel, i know very well how a Intel quad works and a AMD one, its a shame you have not read what i have said properly, please read again with some common sense and post again please?
Ummm i think you are lost wen you say > I don't think they would have spent anymore time in coming up with a true dual-core design based on a broken design, considering that ALL the dual cores from the past including intel are all "true" dual cores, how is it wasting time? if its all ready there? And if this is some how true? and its not, then why in the world isn't intel doing the same thing? it makes even more sense for them to do it since there design of a quad core is alot different and not on one die, it would be alot easier for them to do it compared to AMD, and then after all these so called stuffed quads are noticed, they then gotta go through all of them again, disable the cores, and re pack and whatever else, thats goin to cost a F load to redo all that? Its NOT cost effective end of story.
Sorry m8 but you need to get your facts straight and realize that its just complete stupidity to pump out quad cores that cost ALOT more to make, and engineer and then sell them as a really cheap dual core with all the quad core components in them?
:toast:
This was an intentional part of the design process when they came out with their "Native Quad Core" campaign. Because of how the cores access and communicate with each other, it doesn't matter how many cores are left over, they just work. They could make an 8-core processor based off the Phenom, and have X7, X6, and X5's to release as well. It's a simple architectural design that was implemented to save money, not waste it on binning. All companies do binning and testing, AMD just has an extra step. Think that's less cost effective than scrapping 1-2-3 GOOD cores?
Want to know why Intel can't do the same thing? They use dual core packages, two of em go on a die. If one package fails, they have a Core2. Nothing in-between. Intel doesn't have to worry about making things like their architecture cost effective. They just made it blazing fast, and ate up whatever losses in the record breaking sales they've had over the past year or so.
It wasn't really a mistake on AMD's part to go with the architecture that saves chips, they just didn't invest enough speed to compete with Intel at the high end. Whoops. Let's just hope Deneb kicks it up a notch so we all don't have to watch Intel stomp on the throat of their only competitor, kay?
*lolz, amd totally needs a new architecture so they can get some speed in there. The concept is good though
Is this an AM 2 processor and just a swap with my current processor ?
Has a price been quoted yet ?
MSI's done something sneaky on their site, too -- they used to have seperate CPU compatibility listings for v1 and v2, so that you could know what chips to not use on v1 boards (like mine). That page is now gone, however, so I'm just stabbing around in the dark. I pretty much know to stay away from anything over 95W TDP, though.
That's why I was hoping the Kuma's would be some sort of super-efficient 45W chips or something, but nope.
If the Kuma was just phenoms with 2 disabled cores they would've already been out along time ago. Dont you think? There has been alot of time spent on it and time is money. they already quit making the 6000+ and 6400+ so there is nothing to offer in the higher x2 range so it just wouldnt make any since to have it all along and not sell it. Besides you cannot disable any phenom to just 2 cores then overclock it to 3.6ghz on air like the sample 6500 that was tested. and i expect there have been improvements even from that chip as it ran at 2.3ghz claiming to be 6500+. The real kuma clocked at 2.5ghz is supposed to be a 7550+ and i really hope they just didnt make that number up. All of amds x2s scaled very well in there numerical rated name. Amd has claimed that the kuma would have a new design. It most likely is heavily based on the phenoms but i expect it is a good improvement over current phenoms. They memory controller is new. could they have taken a broken phenom apart and then attached all 4 cores to a new memory controller then disable 2 cores and call it a kuma? Why bother? i dont think the current phenom is powerful enough to benefit from a higher bandwidth memory controller much less one with 2 disabled cores. But for real lets hope there will be something new and fun and fresh to come out. I sure am ready...i am bored of building intels
And welcome to TPU
It would be interesting/nice if these new 65nm Kumas will work on this SB600 mobo. The following 45nm Jumas should also work with this mobo. Just missed a used X3 8750 BE on Ebay for ~$82 + $minor shipping. I was going to get that to replace my excellent 5400+ BE @ 3.2GHz @ stock volts with stock AMD copper pipe X2 6000+ to 95W or 125W X2 and X4 CPU's HSF, and 4GB's (3 used) of DDR2 @400/800MHz. It runs very cool and is fast (for me)and it scored 11,737 in 3DMark06 with Win XP SP3, and with two XFired Saphire HD 4670 @ 770MHz core x 1140MHz Memory (about maximum OC for this Saphire model that is stock at 750x1000). I just have the free demo-test version of 3DMark06. Previously I had a 5000+ BE with two Xfired Saphire 2600XT's and was only scoring in the mid to high 8,000's.
If I may continue with some more slightly OT meanderings for a moment, may I ask if this MSI mobo that you put the copper heatsinks on the MOSFETS, do you think aluminim will be OK and do you think one long piece of aluminun covering all the chips would be OK?? I would hope so and then believe that this mobo would be able to handle at least 95W CPU's and possibly 125W CPU's, but I am not sure and need advice. I have the mobo BIOS flashed to its latest version. Any advice would be appreciated.
These new first model 65nm Kumas, might they not be made from both rejects from the X4 chips and also be purposefulf built 2x cores?? For instance, maybe the lower speed 7550 might be made from the rejected X4's and the faster 7750 be made from purposeful produced X2 silicon?? Maybe, something like that??
I heard AMD will start using metal (maybe also hafnium or similar) in their silicon in 2010, and also start using the ferrite/iron compound chokes or whatever. I am not an electrical engineer nor even an electrician and definitely not into semiconductor work, nor much other work at the present time at that level of brain cell strain/expenditure :banghead:. Previous decades past inebriation episodes casued enough expenditure of that matter anyway, or many ways, whatever, it's a gray/grey area/matter. :toast:
Thanx for any advice concerning the MSI K9A2-CF-F v1.0 mobo and input on the Kumas and future AMD and Intel CPU's. Have an old P4 571 3.8MHz Intel in a micor-BTX setup and it is OK, and never put in my unused PD 940 3.2GHz, and still have an E4700 2.6GHz rig to put together, and also have a P4 3.2GHz Extreme Edition (bought used BTW earlier this year, or was it last year, I don't remember, maybe Alzheimer's or whatever :eek:) for older games etc. and to fiddle with.
Thanx again, Chris
From what I gathered from information I found on the internet, it wasn't a lack of cooling that the MOSFETs had, but a weakness in the power circuits that MSI built into the board -- draw too much power, and the board fries.
Now, if you could buy one of the 89W X2 6000's (like this one), you'll be fine, but any of the 125W Phenom products are very, very risky on this board.
The Kuma's should work just fine, but I was personally going to skip them, since I was looking to overclock the heck out of one of them for my next chip; but if they're already rated at 95W, that's not going to be a possibility with this board.
