Eight-Core AMD Opteron™ 6128(2.0 GHz) $266

AMD Opteron 6276 2.3GHz OS6276WKTGGGU - 16 Core for $ 1175.00

Naopak tenhle je levny.

To mas pravdu
Twelve-Core AMD Opteron™ 6176(2.3Ghz) $1,265

Ceny, ktore som postoval su pri odbere 1000 kusov.

[webwalker]

AMD Opteron 6272 OS6272WKTGGGU 2.1GHz - 16 Core for $795.50

Tohle ještě levnější. Evidentně se platí za frekvence!

DOC_ZENITH: Mluvíš o tomhle?

AMD Opteron 6276 2.3GHz OS6276WKTGGGU - 16 Core for $ 1175.00
AMD Opteron 6272 OS6272WKTGGGU 2.1GHz - 16 Core for $795.50

Nebo o něčem jiném?

JF na otazku ci BD bude mat ACP aj TDP

We will still have both ACP and TDP. With Turbo CORE off, the power will be ACP. With Turbo CORE on, the power will look more like TDP, but will not reach TDP in most cases.

The client version of Bulldozer is Zambezi and it will launch in Q4.

I guess I feel, and maybe I can speak for a lot of people on here, that AMD is crapping on its loyal customers. All we want is some information, something to keep our eyes from blinking, something to keep our faces glued to our favorite PC parts store to get these CPUs, and all AMD is being arrogant in expecting its loyals to stick around with out a shred of information regarding this chip that SO many have been patiently waiting for almost 12 months now.

No offense MR J-F, but reading your posts, you also seem to carry the same arrogant attitude I feel AMD is giving off. Your posts are cold and at many times condescending towards us posters.

I dont think its off base for AMDs loyal customers to expect information at this point. This is deadline #3 that AMD has failed to meet, and its customers are expecting some answers, some truth, and some proof of these CPUs they have been waiting for. Many people have set aside money patiently waiting for this CPU... I dont think its "sad" as some posters on here have said. It's their money. They have every right to be upset that they continue to be pulled around by a corporation that is acting like every other corporation these days. They are arrogant in thinking that their loyal customers will stick around while being treated like they dont matter.

You can call that last comment harsh or way off base, but how can you claim that? Customers have been begging for information now since the first deadline failed to be met. AMD continues to turn its back keeping its mouth shut. How do you expect people to stick around with NO information regarding release, or even performance.

Performance is the KEY issue here AMD. I myself wouldnt mind waiting another 6 months if there was proof these BDs were an INTEL SLAYER. But for all I know its a 3 legged mut racing against a greyhound...

I think at this point this launch will be a failure in the sense that sales will be low at least for the first Q its out, if not longer.

Wow! Dik, diky tyhle citaci si nam vsem rozsiril obzory. Maximalni respekt! Tak prinosnou vec jsem jakteziv necet.

Wow! Dik, diky tyhle citaci si nam vsem rozsiril obzory. Maximalni respekt! Tak prinosnou vec jsem jakteziv necet.

Ten post pěkně vyjadřuje, co si spousta lidí myslí... Celkem nechápu důvod k ironii.

[flanker]

lidi si to mohou myslet, ale tito uživatelé fór púřesto tvoří mizivé procento příjmů...A bohužel AMD má NDA styl jaký má. Nadávkami a "výhružkami" se odpovědi určitě nedočkáme .

[Broxik]

minimalne tito uzivatele for radi svym znamym z nakupem pc tudiz i toto je nejake procento k dobru a jeslti ti flankere prijde ze je amd v tak luxusni pozici ze se muze zakaznikum "smat" zadny problem... ale ono neni ze?

[flanker]

je na tom podstatně lépe, než před pár lety (asi 3 roky zpět), což potvrzují i Quartální výsledky. Věř, že jak AMD, tak Intelu je pár popudlivých koncáků někde. Tam, kde dochází k největším odběrům, tam to mají podchycené.
Já radím taky xx známejm s HW, ale je to jen vše promile objemů.

[THANATOS]

flanker rozpravat tu o tom ako AMD nezaujimaju ludia z fora a ze si to moze dovolit je scestne a vyvolava dojem, ze odklad BD robia naschval aby pohnevali cast zakaznikov co nie je pravda.

AMD Trinity se blíží (první Bulldozer Fusion)

Anand na twitteri povedal zaujimavu vec.

Beware of any leaked Bulldozer benchmarks, unless you're running B2.G you're not looking at shipping performance

Ak niekoho zaujima porovnanie BD a Llano v Sandre tu je citacia a link na uzivatela inf64, ktory urobil zaverecne zhrnutie mojho porovnania. Tie Sandra testy vyuzivaju viac jadier aspon 8, podla vysledkov medzi 2 a 4 jadrovym SB.

speed difference: default speed +86%; turbo speed +140%
core count: +100%

Native Dhrystone/Whetstone (GOPS)
AMD A8-3500M 1.5Ghz(without Turbo) (incl. Radeon HD 6620G) 21.41
BD 2.8Ghz(Turbo 3.6Ghz) 54.64 +155.2%

.Net Dhrystone/Whetstone (GOPS)
AMD A8-3500M 1.5Ghz(without Turbo) (incl. Radeon HD 6620G) 8.99
BD 2.8Ghz 15.73 +75%

.Net Multi-Media (Mpix/s)
AMD A8-3500M 1.5Ghz(without Turbo) (incl. Radeon HD 6620G) 8.84
BD 2.8Ghz 17.66 +96.4%

Crypto CPU (MB/s)
AMD A8-3500M 1.5Ghz(without Turbo) (incl. Radeon HD 6620G) 322
BD 2.8Ghz 925 +187.3%

P.S. moje cpu s 2 deaktivovanymi jadrami dosiahlo v Native Dhrystone/Whetstone 18.23 (GOPS).

[del42sa]

nějak nechápu smysl srovnání Llano na 1,5 Ghz (navic bez turba ) s čipem běžícím na 2,8Ghz s funkčním turbem ??

\\ jo koukám že ho podtaktovali, ale ta hláška že Llano by se mělo jmenovat FX2

To add to TESKATLIPOKA's summary, percentage difference in performance between Llano and BD ES,core for core and clock for clock(I disregarded TUrbo effect in BD,it would only make it a lot worse for Bulldozer so this is "best" case scenario for this,according to "expert savantu",non-crippled ES):

Native Dhrystone/Whetstone (GOPS)
One Bulldozer core in this ES is around 40% slower per clock than one Llano core.

.Net Dhrystone/Whetstone (GOPS)
One Bulldozer core in this ES is around ~2x(~100%) slower per clock than one Llano core.

.Net Multi-Media (Mpix/s)
One Bulldozer core in this ES is around 82% slower per clock than one Llano core.

Crypto CPU (MB/s)
One Bulldozer core in this ES is around 26% slower per clock than one Llano core.

Average from above is ~62% slower per core and per clock. FYI savantu,this is actually slower than Bobcat,which is smaller and has half the resources of bulldozer core (and L2 that is 4x smaller and runs at half the clock). So,yeah,these Bulldozer samples must have been sent to sisoft by AMD themselves . They wanted to show the guys at sisoft how you can cripple a Bobcat core additionally while at the same time upping the transistor count and power draw. Never mind Llano,it is just 60+% faster and should be called FX2 according to these tests

Pan OBR rekl:

Dlouho jsem se odmlčel, bohužel situace v Číně s internetem je žalostná. Je všude a je rychlý, spousta zahraničních domén je ale blokována. Blogspot lze načíst pouze skrze VPN a ještě to stále vláda shazuje ... je to tu těžké, ale alespoň zde nejsou žádné twittery, facebooky, a jiné sledovací služby ...

Až se dostanu do většího města, hodím další výsledky Bulldozeru, nyní skrze 3G a VPN to není možné. Jinak se potvrzují má slova, že BD bude vydán v říjnu za cenu jež jsem vám děcka řekl už před dvěma měsíci. Pokud někdo má informace tak to věděl ... AMD mělo říjen v roadmapě ze srpna ... ti co říkali něco jiného se ukázali jako debilové co neví zhola nic ... já věděl vše a řekl jsem vám to už v srpnu ...

Brzy se ozvu ...
