will the bulldozer core 50% faster in single core performance than phenom-II counterpart? just hope so since they can compress athlon-II core in llano pretty small, cant wait to compare 4,6 core bulldozer with intel mid-range sandy bridge proc whistling.gif

thats awsome,maybe fast because the benchmark all 8 core inside bulldozer die, since they can compress the old athlonII core into much smaller core inside llano, hopes the benchmark true

correction- the cpu that was use for benchmark are 1.8ghz 16 cores bulldozer core doh.gif dont put expectation too much doh.gif

QUOTE(saturn85 @ Mar 25 2011, 09:49 PM)
actually it is the server base bulldozer, interlagos chips with 16 cores. biggrin.gif

hope the desktop version gonna be 8core 3.6ghz doh.gif

Don't hope on cheap prices from AMD already as they have brought back the FX series and most probably their top of the line 8 core processor will be very expensive..
I am expecting that 8 core to outperform current SB offerings but at the same time cost more than the Core i7 2600K as well..I doubt it will be priced on par or lower than Core i7 2600K just to compete with it
*
their new strategy are the different now,i bet the top of the line bulldozer will price on par with core i7 2600k,they dont care about enthaustic market like what intel's offering(980x,990x)
For me they must win in term of performance for the fx series, since bulldozer are purely cpu, not like sandy bridge which include gpu, if the performance are nearly the same, they price will be much lesser
the reason why they return back the fx name, because they want those chip to be leader for performance and return back the glory of the old amd
brah, i want the review for the 6 core right now, high end user wont care about gpu inside the cpu rolleyes.gif

in this product positioning they will priced 4core (2 module) bulldozer higher than 4 core llano with gpu, just hope it will have outstanding performance

I know they are not aiming for the enthusiasts market like the LGA2011/LGA1366..LGA1366 might make sense because it is still cheap
If you scale the price of SB as mid range and SB-E as high end the SB-E would easily be somewhere 1k++ for the processor alone..
I've seen the list of features that SB-E has and I don't think AMD will sacrifice backwards compatibility for oversized socket and quad channel DDR3..
Bulldozer performance seems a little bit vague currently because AMD has not even released much info about it..
But from the architecture side it is actually a different approach than Intel's and 8 core is actually 4 modules which should equal 4 cores to Intel..
I will come to expect many would say that Intel's 4 core is superior to AMD's 8 core instead of looking at how it should be looked at..4 modules not 8 cores  rolleyes.gif
Even more so the Bulldozer module without the L2 cache has the same die space as a single SB core..so a module should be compared with Intel's single core
I am also waiting for the 6 core but AMD marketing team is stupid for making me and the whole market wait.. yawn.gif
Llano will not enter the desktop market yet but it should aim for the laptop market first..E-350 low end laptops are going as cheap as some netbooks already
*
im not really putting to much hope on amd since their rnd budget are much lower than intel, they might release ivy bridge (expected 15% faster than sandy bridge), just hoping the the single core bulldozer performance to have 80-100% of sandy bridge core and price competitively.Of course the 2-3k priced intel processor will win the benchmark, but who can afford that, with amd, im just hoping to get the best bang of the buck offering and we can see the current sandy bridge filling up those offering

by seen that price system,can it fusion with dedicated graphic card like hybrid crossfire?

for the llano, you can only crossfire with hd5500 series only i think...

Those kind of videos are better taken with a grain of salt as the tests are made to show that Llano is better than SB..
In actual fact Intel's processor is actually a lot better compared to AMD's Stars but this test is loading more on the video and graphical based applications..
So actually this test is to show that AMD Llano can handle those multitasking loads as the video processing is offloaded to its GPU making the CPU handle other tasks..
The SB however has to handle all of the load on its own and no matter how powerful it may be..if you make any processor do all the work it will slow down
If Llano CPU portion is made to do all 100% of the workload in that test it will suffer about the same problems as well so the star of the show is the GPU..
*
actually sandy bridge's hd3000 are also being able to do hardware acceleration for video playback and the gpu was use to render the final fantasy 14, however its still pick application for the comparison doh.gif ,but if the llano based notebook(apu only) can be sell under rm2000, i guess its really good bang for buck

i wonder why the next 2012 buldozer must include a gpu, are we reaching the era where computational operation can be easily offload by gpu, hmm.gif guess it will be the revolution of computer era, where gpu takes nearly all process doh.gif

lol,yup you are right, dx11 are just a part for the platform, not including on same die, but u really wondered why intel working so hard to put gpu on its processor and microsoft start to support arm processor and nvidia have a great roadmap for tegra processor maybe on the upcoming year, software can easily utilize gpu resources, yes gpu are far more efficient but its still really too complex to been use

Does AMD mention the release date for Bulldozer, i think they only mention that Q2 for Llano and Q3 for Bulldoze, i think its still within the time frame, looks like lots of manufacturer impress with new 990fx series chipset with the engineering sample, i guess the bulldozer still gonna be great

I think you may be a little confused.

The first gen bulldozer would run on AM3+ and is an FX series. The second gen bulldozer would run on FMx (FM1, FM2, FM3 and etc I presume) and is known as commodore. First gen bulldozer (zambezi) which runs on AM3+ is likely compatible with FMx motherboards, just like AM3 cpus are compatible with AM3+ motherboards. However, FMx bulldozer (commodore) is likely incompatible with AM3+ socket just as how the first gen bulldozer Zambezi wouldn't run on AM3 boards.

AMD's product line chart shows that FMx will be launched in 2012 but doesn't show that AM3+ will overlap FMx which leads me to think that AM3+ will be short lived (6-9 months or so). OTOH, Intel's Ivy Bridge WILL be backwards compatible with 1155 motherboards (some).
*
second gen bulldozer are still cpu (not APU),doubt it gonna use FMx socket unless amd mention that the next bulldozer will be APU, but trinity (next llano with bulldozer core) should still use FMx socket

update: i got it wrong doh.gif
maybe amd doesnt want different chipset for different product class doh.gif
whatever it is im more concern on how zambezi perform without the availability of gpu (with potentially bigger die size) when 4 core bulldozer are expensive than 4 core thuban+600mhz/8rops/400shaders gpu

hope they come up with PCI-E 3.0 for more future proof.

dont worry, there are no graphic card that takes full bandwidth of pci-e2.0 yet, only ultra speed ssd can benefit from the bandwidth for the current time

its 12core vs 6 core, sure bulldozer got advantage if the program can work on multiple core, really worried about Bulldozer IPC sad.gif

3 bulldozer core takes 60-75% cpu usage for running dirt 3 (fps unknown),have lots of resources to use, but too bad that hardly to see games that utilized more than 3 core hmm.gif

bulldozer works like 4c/8t, its truly a disappointment, just hope amd's hyperthread(trademark of intel) technlogy is better than intel equivalent

new bulldozer benchmark, just take it as grain of salt

not sure whether the bulldozer can beat phenom x6,as phenom x6 1090t can score 18555

I thought of the same thing as well  tongue.gif . Its because the site said its 8 core so I thought its 8 physical core, in the end, 4 cores / 8 thread   doh.gif

however it is, the 2nd thread is still pure hardware, not logical, hope the 2nd thread for every module having more than 70% efficiency/performance of the first thread in a module

what will happen if the next amd trinity comes in 1 module for low-end laptop, would it bottleneck so much if it is 1cpu/2thread (as similar to pentium 4 ht)

i wondered why the cpu usage pattern for bulldozer when running dirt3 is like real cpu pattern for every thread, do anyone have cpu usage pattern for ht-enabled i7 processor that we can compare

thanks for this photo,can safely said that amd thread management seems better or it is really physical core
i wondered if we can see any ipc increase per core for bulldozer compared to phemom II x6

wprime@15 second, bulldozer architecture is just a joke, even the llano a8-380 with no turbo is faster than this (13sec+) sweat.gif
maybe something wrong with the optimization/driver, amd please fix this doh.gif
if this true, this is a just a disappointment, an 315mm chip(pure cpu) cannot beat 216mm chip (with graphic)
oh well, hope their hd7000 series didnt fail sad.gif

bulldozer is truly a disappointment, some benchmark even lost to phenom II x6, plus high power consumption also, amd, please dont mess up with the future "enhanced bulldozer" we need competitive cpu
