AMD Bulldozer

Ni še nobenih uradnih testov, tako da se lahko le špekulira o Bulldožerju.
Če ne drugo pa bo verjetno Intel tudi malo pocenil svoje cpu-je po izidu AMD-jevih Buldožerjev.
Tako da počakat se vsekakor splača.

Leaked Buldi test

We start with Cinebench-10. And here we get a core 4074 issues. Approximately 1.5 times less than an Intel core so (both the 2600 and the i5 i7 2500 get about 5800 points. An 'old' i7 965 is around 4900 points)

But the bulldozer hits back hard in the multi-CPU test. Here we see 20615 points. A multiplication of 5.06. We had expected a bit more honest, more close to six times. Perhaps the faster memory to work out better. Yet five times faster is not bad: a hyperthreaded i7 gets just four times. In addition, a very nice score 20,615 points: it is 2000 points more than an i5 2500K and 2000 points less than the more expensive i7 2600K. 11.5-in Cinebench scores Bulldozer with 6.01 points and between the i5 and i7 2500K 2600K in: get the i5 and i7 5.37 6.73 gets points on our test platform. I7 965 sits on a 5.73 points.

Going to 3DMark Vantage, we see a CPU score of 19,119. A perfect score in the top segment. Again between the i5 and i7 in. I7 gets around 22,500 points on the CPU. The total score is an nice 21949 points. Less than an i7 with this card comes out around 25,500. However: every game is without problems on super high detail and resolution to play with this system.

In 3DMark 2011 scores 6616 points in total AMD. Again, neat and a good sign that the processor can feed data to the HD5970. For comparison also take an i7 965 with the HD5970: 7385 points, roughly equivalent to a 2600K i7 with that GPU. Tag is a still faster. With an i5 you're at about the same level as the FX-8150.
Gaming

AMD focuses FX platform especially for gamers. Gamers with separate graphics cards will work, sometimes in CrossFire. We turn therefore take the Dirt3 benchmark at 1920 by 1080 and every detail. The HD5970 has to work hard and certainly not limited by the CPU.

The FX-8150 gets 105 fps on average in this test with a minimum of 75 fps. An incredibly good score, considering the load this game can give both the cpu and gpu. If we look at our platform with the 965-i7 Nehalem CPU, then we - of course with the same settings - at 93 fps and a minimum of 71 fps. Definitely good to play, but lower than the FX-8150.

We turn then still Mafia II. A very CPU-intensive game. There we see that the new platform averaged 68.3 fps able to render. Nehalem setup squeezed out, 76 fps. Just over the Bulldozer. Perhaps some help here 6GB memory.

No no, 5970 pa ne mores rect da je srot, halo

Iz teh testov se samo vidi, kako odlicna graficna je GTX580
Malo draga res, ampak vseeno brez konkurence. Pa se svetlobna leta bolj zanesljivo deluje, kot multigpu.

V bistvu bi blo boljse. Malo kdo ima doma karto kot je 5970, ipd.
No sej se par dni in bomo ze na OC-labu sigurno kak res realen test dobili, ker ce sem dobro opazu si tam nekdo ze, oz. si bo te dni lastil Buldija

Se pravi, tole je bolj odskocna deska za nadaljne izboljsave?

kateri od teh testov obremeni FPU, mogoce kdo ve? in multi-procesiranje?

tale?

jst, so pri teh vecnitnih appih misljene tudi fpu-intensive zadeve? numerika pac, s podporo smp.

Ne verjemte benchmarkom, keri ne prhajajo direkt od AMD-ja.

No, nebi ravno reku, da so od AMDja lažni, so pa editirani(povzetki so narejeni tako, da izpade kot oh in sploh, ampak to je klasični marketing).
Najboljšo sliko dobiš, ko imaš za primerjavo recimo 2 do 3 enakovredne in legitimne znane strani na netu, kjer ima vsaka od njih svojo metodologijo testiranja. Od tam lahko hitro povzameš kaj je res in kaj ne.

Je pa treba brat recenzije, ne samo slikce gledat(primer: igra v kateri grafična x močno prehiti grafično y, ki sta sicer izenačeni, jo lahko prehiti zato, ker ima igra bug, na katerega se obesi vsync, ki se ga na grafični y ne da izklopit- torej, umetna meja je vzpostavljena, na grafu je to jasno vidno(fpsji vedno okrog 60 slik/sekundo, nikoli čez), tudi brez razlage pod sliko, nekateri osebki pa potem lahko zelo zelo hitro pridejo do napačnega zaključka)

Se splača počakat do BD ali i5 2500k? Ker komponentam cene skačejo malo gor malo dol.

@Gibbs007 počaki na Bulldozer-ja, govori se nej bi pršu 12 Oktobra 2011

@knap Govori se 12 Oktobra 2011

Cene nej bi ble:

FX-6100 ~ 190-195$
FX-8120 ~ 235-245$
FX-8150 ~ 275-285$

Ja no nevem tele so najnovejše do zdej.

Pa kje imajo te jajc serverje, da tko po polžje odpira ali je pa tak naval

Dobre novice se hitro širijo, slaba pa še hitreje. Napovedujem 20% upad vrednosti delnice AMD.

A še kdo pomni FiringSquadov preview originalnega Athlona?
Od takrat naprej na tele "leakane" teste ne dam počenega groša. Dokler stvar ni uradno zunaj, ne veš kaj vse v čipu dela in kaj ne.

Lejte, multithreaded aplikacije bodo dokaj dobro delovale, single pa ne. Je pa že na takšni hitrosti (tudi i7 in i5), da tisti, ki ga [Bulldozerja] je čakal, naj ga kupi in pozabi nanj. Edino Benchmarkerji ne bodo zadovoljni.

Real world performance pa ne boš opazil razlike med BDjem, i7 ali i5. Mogoče pri kakšen konvertanju ali heavy usage, ampak takšni ponavadi že vemo, kaj hočemo... v bistvu rabimo in si to tudi kupimo in že imamo.

_{Razen ena anomalija je pri meni: Jaz si GPUje kupujem samo za parkrat na leto, ker samo parkrat na leto igram igre. Škoda denarja, ja, ampak si lahko privoščim 300EUR na dve leti za par tednov igranja.}

Ampak če že kupuješ striktno AMD (zaradi nadgradnje ali drugih razlogov) a ni kakšen X4 višjega razreda, še vedno boljša izbira glede na trenutne rezultate in če potrebuješ večnitnost in najvišji X6 model le nekaj % za BD v tem. Sicer je vredu serija ampak če ga postaviš ob bok prejšni generaciji ni več impresiven in včasih korak nazaj.

ATI je spremenil strategijo in radikalno spremenil tudi arhitekturo, začenši z 4000 serijo. Sistem Lego kock. In očitno je, da mu je 4., 5. in 6. serija uspela.

AMD probava podobno z Bulldozerjem. Koliko bo CPU marketinško uspešen, bomo videli. Jaz upam da bo hit, for Intel's sake. :)

Ja ta tvoj je zelo kredibilen, kjer ga primerjajo z starimi intelovimi procesorji, kot da je tako zelo težko pri vsakem testu dodat score od i5 2500k in i7 2600k.

Why does Lab501 get to break NDA?!
In order to break an NDA you have to sign one first...

I suppose there is also a small chance that all the final BIOS updates for the BD won't be released until the day of the launch
Actually no, there is no chance, because you need reviewers to have time to test this stuff before publishing a review. Nobody makes reviews in one day...

I know!!! Trust me, we retested many times, because we found this hard to believe even if the results unveiled under our eyes. We checked everything countless of times, and still get the same results. Unfortunately, this really is how Bulldozer is performing, and that makes me as sad as any other enthusiast in this industry!

Monstru on AMD's "damage control":
Now the saddest thing is not only the performance, but also the way in which AMD tries to manage this. I heard from a little birdie that some folks at AMD will start calling press tomorrow morning to ask them how reviews are going and try to do some damage control (this reminds me of Nvidia calling press before GTX480 launch). Actually many of the press guys I talked to are a little bit puzzled and don't really know how to approach this situation. From my point of view it is pretty clear, the truth (no matter how much it hurts) is the only way.

Škoda... Tresla se je gora... Rodilo se ni nič :/ Upam, da hitro izdajo 2 ali kaj podobnega in popravijo kar so zdaj zajebal...

Problem je, da Serious Sam 3 še sploh ni izšel ...

Počakajte še na MS update.

edit: Pri kateremu seveda ne bo pisalo "Updates Kernel - BD Perf. resolved," ampak verjetno optimizacije za paket programov.

Nisem poštekal vsega, ampak gre za to, da zaradi omejitev tehnologije CPU interno čekira vsak naslov v dveh korakih- v prvem prečeikira ujemanj naslovnih linij A0-A11, v drugem pa vse ostalo.

Fora je povezana s tem in pa s tem, da ima BD deljen instrukcijski L1, ki pa je samo 2-way asociativen.

Folk je mislu tle potegnit bližnjico, ob kateri pa Linus ni najbolj navdušen.

Men se zdi neumno da razvijajo dva postopka - imajo namreč že delujoč 28 nm za grafe, pa še 32 nm soi High metal K ni izpiljen.... laghko bi šlo na 28 nm direkt in prehiteli Intel.

Glede samega jedra BD:

Po vseh teh letih izkušenj v cpu jih pa mi je tole čudno kaj pišete zgoraj.... po takem bi bil update na PH III ( 32 nm, clock višji, avx, xop , SSSE 4x ipd, večji cache) boljši od BD .



Bomo pa vidli več testov kmalu.



Tale zaključek iz linka zgoraj pa tud nekaj pove:



Conclusion

After comparing all the benchmarks we just like to conclude that AMD Bulldozer can easily take Core i5 2500K from its $230 segment. Also Bulldozer performs almost equal to Intel Core i7 2600K in most benchmarks and 56x performance in applications using complex calculations are really amazing.
Where Bulldozer takes lead? Will Bulldozer suit me?

For $12 more than i5 2500K Bulldozer certainly gives 12 to 40% more performance in all applications and games
With 8 cores, Bulldozer has 4 real cores than Intel i7 2600K and i5 2500K processors
If you are use your computer mostly for productivity applications, video encoding, transcoding processes, which supports multi-cores then without any second thought take AMD Bulldozer. If you want to outperform i7 2600K processors too then you may wait for FX-8170
All Cores Turbo Mode is an excellent feature, because it's almost like safe overclocking, which can be done by anyone
Do you play games at super resolution or do you play with multi-monitor setup using Eyefinity, then Bulldozer can be your first choice
Then finally, do you need a cheaper solution with more cores, having performance almost equal to Core i7 2600K, take Bulldozer

Saj se tudi 2500k draži. Odkar sem gledal, da bi upgrejdal PC, se mi je celotna sestava(cpu+mb+ram) podražila za 30 evrov. Bom pač počakal, trentni čas ni ugoden za nakup.
