Advanced Micro Devices, the world's second largest supplier of microprocessors, said that it had taped out the first central processing units (CPUs) based on the code-named Bulldozer core. The company hopes to begin sampling of the chips with customers shortly and initiate mass production sometimes in 2011.

"In the second quarter of this year we also taped out the first 32nm product based on our new high-performance Bulldozer CPU core. We plan to begin sampling our Bulldozer based server and desktop processors in the second half of this year and remain on track for 2011 launches. These new processors will deliver significant performance improvements to the AMD platform," said Dirk Meyer, chief executive officer of AMD, during the quarterly conference call with financial community.

The "tape out" means that the artwork for the photomask of a circuit is sent to manufacturing. It is unclear at this point whether AMD has already received samples of the Bulldozer processors back from manufacturing and assembling or at least manufactured wafers from Globalfoundries. Moreover, it is uncertain when exactly AMD submit the design of the chip to its foundry partner: back in April, or back in June? At present it takes weeks to manufacture a complex multi-layer chip, so, the timing of the tape out is really important for analysis.

According to an unofficial source familiar with AMD’s server plans, the chipmaker intended to commence mass production of certain versions of its Bulldozer-based code-named Interlagos microprocessors with 12 or 16 cores already in the first half of 2011. Other versions of the chips, e.g. with reduced power consumption or increased performance, were planned to be produced in the second half of the year.

While generally AMD formally unveils microprocessors when it begins mass production or revenue shipments of its chips, it is not set on stone that initiation of mass production means formal announcement. From the current point of view the information means that AMD has equal chances of launching its sixteen-core or twelve-core AMD Opteron “Interlagos” processors either in the first half of the year or in the second half of the year.

AMD Opteron 6000 “Interlagos” will be compatible with AMD’s Maranello server platform with G34 (1944-pin) sockets. It is expected that Interlagos features two code-named 32nm SOI Valencia chips with six or eight cores on the same piece of substrate.

Based on the information provided by AMD during its annual Analyst Day in November '09, the first Bulldozer chip code-named Zambezi (which belongs to Orochi family of desktop chips, according to the firm) will feature eight x86 processing engines with multithreading technology, two 128-bit FMAC floating point units, shared L2 cache, shared L3 cache as well as integrated memory controller. AMD also states that the new CPU will feature “extensive new power management innovations”. Based on the diagram that AMD demonstrated, the company intends to dramatically improve multithreading performance of its CPUs: two INT schedulers, an FP scheduler and separate data caches for each of four cores should do the job very well.

Evo malo o arhitekturi.

Bulldozer je prvi x86 procesor koji ima serovani L2 kes. Bice to krajnje zanimljivo parce silicijuma

bigl ne radi ti link za sliku eror 404..btw deluje prilcino..obecavajuce

Hmm... Zanimljivo bi bilo da se sazna kako se Bulldozer perdstavlja operativnom sistemu u kontekstu broja logičkih jezgara i CPU-Z-u u kontekstu broja fizičkih jezgara i broja thread-ova.

@ivan90BG
Identifikovace ga kao oktakore, ali bez virtuelnih jezgara... Ali nisam siguran sta ce CPU-Z pokazati (verovatno ce morati da se pise od nule za Bulldozera).

[Beagle]

Evo ga i Bobcat. Iznenadjujuce mali cip! Integrisano graficko jezgro, BGA pakovanje i TDP od samo 9W.

AMD to Start Production of Desktop "Bulldozer" Microprocessors in April.

AMD Bulldozer desktop CPU roadmap detailed

As you probably found out last week, AMD's first Bulldozer processors, codename Zambezi, are scheduled to debut in Q2 2011 targeting the desktop market. Courtesy of a leaked slide we now know that the Bulldozer wave will include quad-, hexa- and octo-core chips.

The first arrivals, expected in late March/early April, will be the 8-core Zambezi CPUs packing 8MB of L3 cache that have a TDP of 125W or 95W, depending on frequency. Next up, around mid-Q2 we'll get the 6-core models with 6MB L3 cache and the 4-core chips with 4MB L3 cache, all featuring a 95W TDP. The Zambezi processors are manufactured on 32nm process technology and will come in a AM3+ package.

AMD 9-series chipsets come in Q2 2011 to welcome Bulldozer

Not surprisingly, beside the Zambezi Bulldozer-based CPUs and the Llano Stars-based APUs, next year AMD will introduce multiple desktop (and mobile) chipsets featuring support for AM3+ parts. These chipsets are known as the 9-series and are set for a Q2 arrival.

A quick look over the allegedly leaked roadmap below reveals that, at least for the desktop segment, AMD is planning to release four chipsets in Q2 - the 980G with integrated graphics, and the IGP-less 990FX, 990X and 970. These will be paired up with the SB950 and SB920 southbridges, both of which provide six SATA 6.0 Gbps ports (yeah Intel, six) and 14 USB 2.0 ports. The SB950 'flagship' also adds RAID support and two extra PCIe 2.0 lanes.

The 980G includes a 560 MHz-clocked DirectX 10.1 graphics core, UVD 2.0, support for a PCIe x16 slot, and DVI, HDMI, and DisplayPort outputs.

The 970 and 990X are quite similar except the former doesn't support CrossFireX, while the latter is capable of an 2 x PCIe x8 setup. In contrast, the 990FX enables two PCIe x16 slots or four PCIe x16 @ x8.

Ovo moze da znaci da Buldozer nije ispunio ocekivanja sto se tice performansi. Sa druge strane.. moze da znaci bilo sta.

Evo i prve AM3+ ploce:



Ako ja dobro vidim, ova ploca ima digitalnu napojnu. Impresivno za AMD. I crni socket

[Thaedass]

^ Trebalo bi da jeste Btw imam slike te ploce vec duze vreme,ali ih nisam upload-ovao (Intel fan )



AM3b Socket



Ako smem da primetim i da dodam licno misljenje,dizajneri MSI-a su igrali na sigurnu kartu - sistemu hladjenja fali samo ROG oznaka Bukvalno prekopiran od C4F... Dobro,preterujem,ali malo su mogli da pripaze na taj detalj

[ivanza]

Pozitivno je što AM3 procesori mogu da se stave na AM3+ ploču. Mada pitam se da li bi se primetila nekakva razlika ako bih npr. sa Amd-om 955BE prešao sa AM3 ploče (GA-MA790XT-UD4P) na neku AM3+ ploču sa 990X čipsetom ?

Da li može AM3 kompatibilni kuler kao što je npr.CM Hyper 212 (ne Plus i Plus verzija) da pasuje na AM3+ ploču ?

[Thaedass]

Well trebalo bi da AM3 procesori mogu da se ubace u AM3b podnozje jer bi u suprotnom to bio nagli prelaz (za AMD) na novo podnozje. Nisam nasao ni jednu zvanicnu informaciju vezano za ovo polje

Sto se kulera tice,primecujem par razlika na sistemu kacenja izmedju ova dva podnozja. Prvi utisak je da nece pasovati..

CM Hyper 212 (ne Plus i Plus verzija) da bi se nakačio na ploču potrebno je skinuti ovaj plastični nosač procesora u potpunosti i pomoću Amd backplate i ostalih džidžu mižu koje dolaze uz njih, isti se šrafe na ploču.

Da li si možda mislio na promene u plastičnom nosaču procesora ili si mislio na raspored rupa na ploči preko kojih je plastični nosač pričvršćen na ploču ? Ako su rupe na AM3+ ploči drugačije raspoređene u odnosu na AM3 ploče (u smislu na razmak između njih) onda ne može da pasuje.
