Ovo i jeste glavna prednost Fusiona... klasican desktop ce polako izumirati kada je vecina primena u pitanju, samo je pitanje kojim tempom ce se to desavati.
Sad se nesecam koja je najavljena potrosnja ali nemoguce da ponudi performanse 5670 uz full load GPU/CPU, znam da se spominjao smesan TDP od ~30w
Šta to znači? Da ćemo svi preći na konzole za igranje i laptopove da za korišćenje neta i kucanje u wordu?
Opet kazem, sve i da bude 400SP, ne treba ocekivati performanse 5670 karte u igranju, ali je to opet znacajan napredak u odnosu na sve integrisano sto sada imamo. Na kraju krajeva, daleko manji Ontario je na onoj demonstraciji pogurao AvP u DX11.
Po meni da... igranje jos i nekako, nece PC kao gaming platforma bas izumreti, ali stvarno ne mogu da zamislim svakodnevno paljenje desktop racunara samo za internet i druge uobicajene poslove. Ne bih bas prognozirao kada ce se to i desiti, ali mislim da svakako hoce.
Ako se to usporedi s AMD-ovom Llano arhitekturom, onda jedina stvar koja fali je on-die EDRAM.
Hmm,a odakle FP jedinici u Phenom-u 4 128bit pipeline-a od kojih su 2 fmac?? :d
Bulldozer deluje impresivno na papiru,samo jos da vidimo kako radi u praksi![]()
Nothing about Bulldozer looks like a huge gamble. When considered in the context of other very wide SMT designs from IBM and Intel, Bulldozer is actually a conservative, evolutionary step forward from what has gone before.
Q: “How much extra performance will we see when running two-threaded applications on one Bulldozer Module compared to two cores in different modules?” – Simon
A: Without getting too specific around actual scaling across cores on the processor, let me share with you what was in the Hot Chips presentation. Compared to CMP (chip multiprocessing – which is, in simplistic terms building a multicore chip with each core having its own dedicated resources) two integer cores in a Bulldozer module would deliver roughly 80% of the throughput. But, because they have shared resources, they deliver that throughput at low power and low cost. Using CMP has some drawbacks, including more heat and more die space. The heat can limit performance in addition to consuming more power. Ask yourself, would you rather have a 4-cylinder engine that delivered 300HP or a 6-cylinder engine that delivered 360HP and consumed less gas? The cylinder to horsepower ratio for 4-cylinder is obviously higher (75HP/cylinder vs. the V6’s 60HP/cylinder), meaning that each cylinder can give you more performance. However, looking at the overall enginge, you are getting less total output; and you are getting that lower output at a higher cost (higher gas consumption).

Nekako mi se čini da će 8/16 biti MCM kao što je i Magny-cours ... ostaje da se vidi.
The first question this architecture brings up is, what is AMD's definition of a core? That one is easy, they define it as an integer core with full pipelines. Sun and many others do the same, and there are a lot of cores out there without any FP hardware, so this makes a lot of sense. A Bulldozer module is therefore two cores plus shared FP resources, x86 decoders, and memory/cache interfaces.
Ma, sve to kužim što se tiče arhitekture, samo kažem da licenciranje softvera nije baš u njihovu korist.
Pojavile su se neke informacije (spekulacije bolje reci) koje govore o veoma visokim radnim frekvencijama Bulldozer cipova...
Bulldozer is a high frequency optimized CPU, a so called speed demon. This approach has fallen out of popularity in the x86 world, due to Intel’s misadventures with the Pentium 4. In all fairness though, many of the Pentium 4’s problems were unrelated to high clockspeed and more closely tied to the actual microarchitecture. In the high-end server world, IBM has successfully pursued high clock speeds with the POWER7. So a speed demon approach can work out successfully. Bulldozer has a fairly lengthy pipeline, to minimize the gate delays per stage. AMD was unwilling to share any specifics on gate delays, although some discussions at comp.arch suggest a target of ~17 gate delays vs. ~23 for Istanbul. To tolerate the increased latencies necessary for a high frequency target and to efficiently share resources between cores, Bulldozer introduces decoupling queues between most major stages in the pipeline.
Mene najvise interesuje misljenje Hansa De Vries-a! Nisam cuo da se on oglasavao! AKo jeste mozda neko ima link, pa neka baci ovde!
daj link!Jedino sto sam video je onaj saljivi post na XS-u.
Verovatno misli na ovaj post
The package measures about 1.5 x 1.5 cm edge length, the die of the APU itself is slightly smaller than the one RV810 GPU (63 mm ²), see picture above. Zacate points, as already mentioned, a TDP of 18 watts on, the "little" brother, Ontario with nine watts exactly half. The new "High-speed bus between the CPU and GPU core should also have been highly optimized for GPU computing applications and play only the true strengths of the APU can.
Also a new statement on the performance we were able to be carried away AMD, the APU is to Zacate appreciably faster than an Intel Pentium Dual-Core (Core-based be)....
Ontario bi mogao biti pravo iznenađenje iz TSMCa.
