Looks like the sample got some problems. biggrin.gif

After looking at so many 'leaked' benchmarks I would usually take it with a grain of salt, especially with Cinebench. I lost count already how many I saw a Photoshopped version.

That's rather slow TBH.The Cinebench R11.5's score is even lower than the i5 2500K sweat.gif

The TS got real engineering sample. He got photo on that. smile.gif
Anyway, his unit apparently, got some problems. biggrin.gif

If AMD can give me a quad-core that is noticeably faster than my Phenom II X3 710 on single threaded apps, isn't any hotter, AES-NI and CPU+MB pricing of about RM700, I'm sold. tongue.gif

Okay, the next gen APU, Trinity will got HD6770 core integrated. brows.gif.
But I think the RAM will become bottleneck. sad.gif

For APU users, time to get performance RAM and OC it to get better IGP performance. icon_idea.gif

Have the same feeling cause share system ram right?
Btw 8core series with built in graphic?

No. smile.gif
FT1(APU) - 2/4 cores+IGP
AM3+ - 4/6/8 bulldozer cores. IGP from chipset.

Trinity (Next Gen APU) - 2/4 bulldozer cores+IGP

The RAM issue with the APU is already known for quite some time. It has more to do with the bandwidth that the RAM has rather than speed. For a discrete GPU you have a very big bandwidth compared to what you can find on normal RAM. Only solution is to have a dedicated memory for the GPU on the motherboard which was not implemented maybe due to cost. Another solution is to increase the dual channel memory to triple/quad channel memory but have to wait till AMD decides to actually implement.

Putting the RAM issue aside, the number of pins on the socket could have been increased as well. Now the CPU and GPU have to share the 905 pins that Socket FM1 have which might not be a good thing.

So is there any new bench for the 8 cores monster?

According to the pic
2.80GHz BD lose to 2.80GHz i7
This is dissapointing
But the announced stock speed should be 3.60GHz
Wanna ask
If the speed is 3.60GHz means all 8 cores run at 3.60GHz?

Now only I know about this
So that means the APU'S GPU will share the memory of the normal RAM?

I already said, there are some bugs with the tested sample.
When OC-ed to 3.2GHz, it shows performance decrement. LOL. laugh.gif

Did you notice, engineering sample? laugh.gif
Yes, all cores will run at same clock.
If you enabled C-state, cores may run at different frequency, depending on workload on that particular core.

Yep.

Some super impressive result has came. Broke the IGP record. brows.gif

Dunno whether I should buy the zambezi cpu or the trinity apu.... Rumour said that trinity will be released in march/april 2012 while zambezi will be released in august/sept 2011.... But I reli like the trinity apu... Looks promising

The beauty of going AMD is that you don't have to deal with the socket BS that Intel is feeding us. You can go with whatever CPU and just swap it out without changing the whole platform.

That may change when AMD introduces the Komodo to replace the Zambezi. The Komodo is supposed to be an APU so that might be the point that the Socket AM3+ is no longer useful. If according to the timeline Komodo should come out next year and most likely a new Socket will be introduced as well. After they have transitioned to the newer socket then backwards compatibility would continue from there and not backwards compatible with AM3+.

Of course this is all speculation and might have some truth but if AMD really wants to change then they might as well go all the way by bringing down their Socket C32 or Socket G34 for Komodo which has a lot of contacts points and LGA. brows.gif

The performance improvement is decent.  smile.gif
Without L3 cache, it is still able to perform on par with Phenom II.  smile.gif
*
I think it should be faster than Phenom II.
Do you expect it slower than Phenom II?

I hope it is faster than Sandy Bridge too, clock to clock.
Bulldozer is AMD's biggest project ever. A big hoo-haa since 2005.
I expect it to blow Sandy Bridge out of water. It would be a bit of turn-off if this AMD's "greatest" architecture fails to beat Intel's.
I don't expect it to be cheap though. I think the price doesn't matter as long as it's faster than Sandy Bridge - the performance justifies the price.
