Torej da ne bomo mešali tem z Phenom II, sem odprol novo temo za AMD Bulldozer.

AMD Bulldozer's Clock-Speeds May Be Higher than 3.50GHz.
AMD Releases Clock-Speed Related Information About Bulldozer Micro-Architecture

At the International Solid-State Circuits Conference (ISSCC) 2011 Advanced Micro Devices plans to reveal additional details about its code-named Bulldozer micro-architecture as well as implementations of forthcoming microprocessors on its base. Apparently, AMD's next-gen chips will be capable of working at over 3.50GHz, which is a quite high-speed, considering the fact that the central processing units (CPUs) will have up to eight cores.

During an ISSCC session on the 21st of February, AMD will describe its dual-core processor module of eight-core Bulldozer microprocessor, according to the agenda on the web-site of the conference. During another session on the 22nd of February the company will describe implementation of its 8MB unified level-three cache of Bulldozer microprocessors. The presentations will be dedicated to ways of reducing die size, power consumption as well as improvements of yields. The description of the sessions shed more light onto the characteristics of AMD's implementation of Bulldozer micro-architecture on 32nm silicon-on-insulator process technology, which is known as code-named Orochi design (Zambezi is desktop version, Valencia is server version).

Each Bulldozer dual-core CPU module with 2MB unified L2 cache contains 213 million transistors and is 30.9mm2 large. By contrast, die size of one processing engine of Llano processor (11-layer 32nm SOI, K10.5+ micro-architecture) is 9.69mm? (without L2 cache), which indicates that AMD has succeeded in minimizing elements of its new micro-architecture so to maintain small size and production cost of the novelty.

Bulldozer processor modules are designed to operate from 0.8V to 1.3V voltages at 3.50GHz+ clock-speed. It is unclear whether 3.50GHz is average clock-speed of the forthcoming Orochi processors or they will manage to work at significantly higher frequencies. Interestingly, but the level-three cache of Bulldozer may work at a clock-speed that is lower compared to the frequencies of CPU modules.

"This micro-architecture improves performance and frequency while reducing area and power over a previous AMD x86-64 CPU in the same process. The design reduces the number of gates/cycle relative to prior designs, achieving 3.5GHz+ operation," the claim by AMD reads.

The Bulldozer's 8MB L3 cache is composed of four independent 2MB sub-caches and features column-select aliasing to improve area efficiency, supply gating and floating bit lines to reduce leakage power, and centralized redundant row and column blocks to improve yield and testability. The cache operates above 2.40GHz at 1.1V. Potentially, this may be an indicator that Orochi will work asynchronously.

While presentations from ISSCC do not reveal precise peculiarities of future microprocessors, they give indicators which may reveal certain general qualities. For example, according to an ISSCC 2010 paper claims that the target CPU clock-speed of Llano, which is made using the same fabrication process as Orochi, is "higher than 3.0GHz". Indirectly this points to high-frequency/scaling design of Bulldozer.

AMD did not comment on the news-story.

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

Engineering Samples of AMD's Next-Generation Desktop Chips Due Next Month

Advanced Micro Devices will start production of its code-named Zambezi central processing unit (CPU) based on the highly-anticipated Bulldozer micro-architecture in April, 2011. Initially AMD plans to release 8-core microprocessors for desktops, but later in the second quarter of next year the firm intends to launch six-core and quad-core chips based on Bulldozer micro-architecture.

The first engineering samples of Zambezi chips that will be available for AMD's partners for testing will be released already in December, 2010, about a month from now, sources familiar with AMD plans told X-bit labs. Production candidates should be ready by February and the initial production of the company's first desktop microprocessors powered by the long-awaited Bulldozer micro-architecture is scheduled to start in April next year. Probably, the launch of the chip will occur around the same timeframe.

The first Zambezi microprocessors to be launched are expected to be eight-core products with 95W and 125W thermal design power as well as 8MB L3 cache. Later in the second quarter of 2011 AMD, according to sources with knowledge of the company's roadmap, will release six-core chips with 8MB L3 cache and four-core products with 4MB cache. All of the processors will feature TurboCore 2.0 technology, dual-channel DDR3 memory controller with up to 1866MHz memory support and will be compatible with AM3+ mainboards.

Eight-core Zambezi/Orochi features four dual-core Bulldozer modules, each of which is believed to have 2MB of shared level-two cache, that will share 8MB L3 cache. In total, the whole chip will pack in whopping 16MB of SRAM, a 77% increase from the current six-core microprocessors that have 9MB of cache in total.

It is noteworthy that AMD's Zambezi microprocessors made using 32nm silicon-on-insulator process technology by Globalfoundries will be available earlier than the company's code-named Llano chips that combine current-generation x86 cores with current-generation DirectX 11 graphics engine on the same piece of silicon.

AMD Orochi design is the company's next-generation processor for high-end desktop (Zambezi) and server (Valencia) markets. The chip will feature eight processing engines, but since it is based on Bulldozer micro-architecture, those cores will be packed into four modules. Every module which will have two independent integer cores (that will share fetch, decode and L2 functionality) with dedicated schedulers, one "Flex FP" floating point unit with two 128-bit FMAC pipes with one FP scheduler. The chip will have shared L3 cache, new dual-channel DDR3 memory controller and will use HyperTransport 3.1 bus. The Zambezi chips will use new AM3+ form-factor and will require brand new platforms.

The Sunnyvale, California-based chip designer plans to introduce AMD 900-series chipsets compatible with Zambezi processors in Q2 2011. The Bulldozer processors, Radeon HD 6000 "Northern Islands" discrete graphics cards and AMD 900-series core-logic sets will power AMD's next-generation enthusiast-class platform code-named Scorpius.

Že obstoječ 6 jedrnik je po P/P bolj konkurenčen. Ti pa itak sam intela vidiš... drgač pa v tej temi rabimo pametne debate.

jazbec ::

sm slučajno rekel da ni
in ne vidim samo intela vidim tudi amd-prej bi reku da ti vidiš samo amd

načel nisem nobene debate-leti na to da rabiš pametno debato

pa i5-2500k ima tudi zelo dober p/p;)

sem že dva krat pohvalil intel da napram 1366 in 1156 drastično zboljšal P/P... 6 jedrni intel je še vedno 900 eur samo cpu. sam to še vedno ni Amd.

jazbec ::

6 jedrni intel je itak meni osebno zelo precenjen
saj smo vidli da ga i7-2600k celo prehiti v večini testov-stane pa 340 evrov

i5-2500k pa ima zelo dober p/p ker mu spet konkurira za ceno 230 evrov
cene plat so tudi tako opremljene kot amd-jeve za malo denarja(za 100 evrov dobiš že dobro plato)

tko da je intel z sandy bridge naredil zelo velik korak z p/p
ampak še vedno ni tak kot p/p od amd-ja

Dr_M ::

Se vedno me pa zalo zanima ali bo 4 modulni cpu kot 8 jedrnik ali 4?
Ce bo 8, bo to bl svoh, ce pa kot 4, bo pa to najhitrejsi 4 jedrni procesor. :))

Kar se tiče cene plat je pri AMD najbolj opremljena okrog 190e pri Intelu pa to krepko prekaša.

TOP, pa sej malo kdo kupi res top plato, tako da glej p/p plate in do zdaj si pri AMDju dobil dobro plato za 60-90EUR na kateri si mel CF, usb3 in sata3 kar je blo pri Intelu vsaj ene 120EUR. Zdaj pa ze lahko dobis dobro plato tudi pri Intelu za 100EUR in i5 2500k za ta denar je bestbuy zadeva. Proti tej kombinaciji AMD pusne tudi v p/p ker je precej bolj zmogljiv za niti ne tako veliko razliko v ceni. Ampak 2500k in 2600k bomo primerjali z buldozerjem ko pride ker ta primerjava ni lih "fer", ceprav trenutno je to to kar se na trgu dobi.

Če bo AMD štel eno jedro za dve, potem bo zadeva relativno skromna se strinjam. Ampak pohitritev naj v bi bila do 50% :

Sam na to gledam s praktične strani.

Končal sem pri AMDju in tega sem kar nekako vajen. Težko mi je spremljat hkrati dogajanja v vseh taborih, vem pa, da bom pri AMDju dobil nek ustrezen ekvivalent. Če bo čip boljši od konkurence, bo pač dražji, sicer bo pač malo cenejši.

Zdaj, če bi se ukvarjal s čem ozkospecializiranim, recimo enkodiranje videa, kjer bi konkurenca blestela bistveno bolj, potem ne rečem.

Ampak za moj mix potreb je prava figa.

Poleg tega rad podpiram AMDja, ker je pač manjši, ker je utrpel škodo zaradi nelojalne konkurence in ker je edini Intlov konkurent. Ostali zaradi ptaentne zaščite ne pridejo zraven.

Aja, pa zaradi tega, ker kar nekako sodeluje na polju odprte kode. Razvoj in odprtje driverjev za njihove grafikulje je pri meni velik plus, čeprav sem še vedno pri nVidii...

V prenosnikih, kjer doslej AMD ni dajal prave konkurence imam pač Intla, pa še tam bolj zato ker je bil v kombinaciji zaslona, kartice in cene, ki sem jih hotel pač Intlov CPU...

V določenih aplikacijah verjetmo res bo. V določenih bo pa daleč zadaj. Na grobo rečeno bo 4-jederni Buldožer odvisno od aplikacije deloval kot 4 ali kot 8 jedernik, ozeroma nekje vmes.

Prihodnost se imenuje AMD- Berite tole :):

AMP! Edition @ T-Break Bulldozer 50% Faster than Core i7 and Phenom II
Here, take some salt. AMD reportedly gave out performance figures in a presentation to its partners, performance figures seen by DonanimHaber. It is reported that an 8-core processor based on the "Bulldozer" high-performance CPU architecture is pitched by its makers to have 50% higher performance than existing processors such as the Core i7 950 (4 cores, 8 threads), and Phenom II X6 1100T (6 cores). Very little is known about the processor, including at what clock speed the processor was running at, much less what other components were driving the test machine.

Taking this information into account, the said Bulldozer based processor should synthetically even outperform Core i7 980X six-core, Intel's fastest desktop processor in the market. Built from ground-up, the Bulldozer architecture focuses on greater inter-core communication and reconfigured ALU/FPU to achieve higher instructions per clock cycle (IPC) compared to the previous generation K10.5, on which its current Phenom II series processors are based. The processor is backed by new 9-series core logic, and a new AM3+ socket. AMD is expected to unveil this platform a little later this year.

Ponavadi je tako, da najdejo (naredijo) eno aplikacijo, v kateri so res taki rezultati, v ostalih pa vemo koliko je razlik... Sam pustimo se presenetit. Sem pa sam dost skeptičen, če tako dolgo niso nič konkurenčnega po preformancu spacali, pomoje tud zdaj ne bodo (6 jeder počasneje kot 4 Intlova)...

Zato pa je tudi cena postena :> glede na to,da je to nova arhitektura,bi moral bit novi procesorji precej hitrejs. AMDju to ponavadi dobro uspeva,ce bodo le imeli dober proizvodnji proces.

Zakaj pa ne? Če hoče jih lahko tudi s stotimi.

Jst ::

Jaoo AMD. Kaj si moral narediti takšno zmedo s temi jedri. PR oddelek takoj odpustiti.

Kot vemo en BullModul vsebuje 2 INT jedra + 1 FP256 jedro, ki pa lahko deluje kot dva FP128.

Če aplikacija uporablja samo INT bo 8 jedrnik delal kot 8 jedrnik. Best case scenario. Če bo program zaposlil FP del z FP128, bo enako delal kot 8 jedrnik. Če pa bo 8 jedrniku program dajal delo samo za FP256, bo pa delal kot 4 jedrnik. Kar je Worst case scenario.

Pametno so tole arhitekturo "naklamfali" skupaj.

Škoda le, da je toliko dezinformacij in napačnih interpretacij Bull Modula.
