Ovo bi možda bilo prikladnije za temu Liano 32 nm

Još nekoliko informacija vezano za Buldozer, tačnije radi se o overklokovanom FX 8130.

AMD FX-8130P overclockan na 5.1GHz na zracnom hladjenju (1.6V) i vrti SuperPi 1M na toj freq..

Max stabilna frekvencija u Cinebench R11.5 je 4.8GHz..

The Bulldozer FX-8130P is an 8 Core/ 8 Thread Processor which comes with 8MB L3 Cache, Pricing and Info here. The guy managed to overclock the CPU to 5.1Ghz (1.596) volts with the help of Asus Crosshair V Formula motherboard (Detailed here) along with 4Gigs of ram.

Two benchmarks were used to check the stability of the processors overclock, The max stable overclock achieved with CineBench R11.5 was 4.83Ghz (4834.2mhz) while 5.1 (5077.6mhz) with Super Pi Run. Looks like the Bulldozer are good for massive overclocking using some good heatsinks, The user used a Noctua NH-D14 heatsink to achieve those clocks however temps and benchmarks results have not been shown. OBR is teasing around with some other videos to which we mentioned in the news posts below.

Naravno ovo je teaser i svi postignuti rezultati u benchovima nisu dostupni..

Po većini nezvaničnih najava ovaj Buldozer trebao bi da se jako dobro klokuje, što potvrđuje i prethodni post.

I sta je tu novo vs SB ?

I call hype bullshit on this one 5.1ghz na 1.6v. Ali hajd, dok ne dodju benchevi, ne mozemo baljezgat.

kolinsb · Jul 6, 2011

pa jedino sto je novo, jeste 8 fizickih jezgri, a ne 4 fizicke + 4 logicke jezgre. vidjet' cemo sluzbene rezultate, oni ce sve pokazati, da li ima jos nesto novo

Česi ko "nešto" testirali:

Da li je na 8 jezgenom Buldozeru podržan HT?

kolinsb · Jul 7, 2011

pa HT je intelova "tehnologija" pa stoga nema HT na AMD-u to je isto da kazes, je li SLI podrzan na ATI grafikama

selvin · Jul 7, 2011

@kolins,
Postoji hypertransport i hyperthreading Prvi amd-ov, a drugi intelov. Prvi se cesce zove ht, drugi htt.

Podrzan je valjda HT 3.1.

kolinsb · Jul 7, 2011

pa valjda je mislio na hyper-threading, jer je quote-o moj navod u kojem spominjem fizicke i logicke jezgre

Htio sam da pitam hoće li biti kod Buldozera neka vrsta logičkih jezgri kao kod intela?

kolinsb · Jul 7, 2011

koliko je znam, AMD je velik "protivnik" tog koncepta. Oni navodno vjeruju samo u fizicke jezgre logicke jezgre smatraju nekakvom obmanom kupaca.

WhiteNinja · Jul 7, 2011

Čini mi se da je bilo nekog govora o tome da će i AMD integrisati tu tehnologiju u svoj novi procesor, čisto radi boljeg iskorištavanja resursa CPU-a. A i sam znam da je dosadašnja njihova politika bila ono "True core" itd.

Dog_Father · Jul 7, 2011

Bulldozer ima po dvije jezgre vezane u modul, ali ce sistem taj modu i dalje prepoznavati kao dvije fizicke jezgre. U tom smislu, jedan Bulldozer modul se usporedjuje sa jednom Intel jezgrom sa HyperThreadingom. Nece biti logičkih jezgri, ali ima nekakvih "novih" tehnologija (cluster multithreading npr).

jel to dobro ili lose ?
spram ovih intelovih u ovom rangu

Pa poprilicno je saroliko, ali i obecavajuce.

In addition, it took 19.5 seconds to complete SuperPi 1M, which is much slower than Intel competition. However, in real world benchmarks, the story is rather different. In X264 Pass 1 the Bulldozer sample (henceforth mentioned as simply "BD") results a whopping 136.29 fps. To put this in perspective, Intel's fastest CPUs can only manage ~100 fps. However, it is always Pass 2 that is the real test. BD completes with 45.39 fps. The typical speed for a Core i7 2600K is ~36 fps, while Intel's 12-thread goliaths complete in the ~47 fps range. BD is clearly far superior to the 8-thread Sandy Bridge, while nearly catching up to the Gulftown champions.

Even more impressive is the 3D Mark 11. While this score depends from platform to platform, when coupled with a GTX 580, the previous 3D Mark 11 champ Core i7 2600K struggles to achieve the P6000 mark, typically. BD easily sails by with P6265. In Fritz Chess, BD overpowers Core i7 2600K yet again, with a score of 14197 kn/sec. However, it falls short of Gulftown CPUs, which are typically in the 17000-18000 range. Finaly, in Cinebench R10, BD returns a score of 24434. With this score, it slots right in between Core i7 2600K and Core i7 990X.

The results are consistent, for the most part. In multi-threaded applications, BD significantly outperforms Core i7 2600K, and almost catches up with 6-core Gulftown. In less muti-threaded applications, like 3D Mark 11 or X264 Pass 1, thanks to an incredible 1 GHz Turbo Core, BD overtakes Gulftown CPUs. In all situations, BD ended up well ahead of Core i7 2600K. In every situation, BD was massively faster than Phenom II X6 1100T - more than 50% in many cases.

Of course, these benchmarks and comparisons should be taken with a grain of salt - especially it being an engineering sample. If previous rumours of stock clocks up to 3.8 GHz and a price tag of only $320 are true, AMD could have a real winner on their hands. Even with the engineering sample's clock of 3.2 GHz, a $320 is a bargain for a CPU of this power, wiping floors with the mighty and similarly priced Core i7 2600K. Having been delayed, FX-Series CPUs are now expected to release for desktops in the late August / early September timeline, with more information expected in the coming weeks.
