Evaluation of the 45nm AMD Deneb Reveals an Efficient Processor in the Making

What switch?

Last intel was a PIII that died.

How you so wicked to yourself bredda?

Why are you being so cruel to yourself?

where did you get your infos from?
We still know nothing about the architechture of the denebs.And i wouldn't believe those chinese sites.I remember before the 4800 series was released a chinese site claimed that they got a 4850 and they showed the specs via cpuz and the card had 480 stream cores which appeared to be 800 later.

first confirm your infos, then you can base your conclusions on them.

First I agree with you that this could be a false/misleading post.

Next, I remember reading something regarding their no architecture change here at TPU. If I find that article I will post a link.

Next, AMD never boasted about a new architecture in the process, it always says that it has fine tuned.

If you find something to prove then please do post here.

If this is even remotely correct, it seems that AMD is on a roll!

The lower power consumption would be excelent news in numerous ways, but what comes to mind first is the server front. In server business the nr.1 enemy is heat and power draw, with the new 45nm process AMD could tackle those both and make great increase on their server market share.

Incredible Power saving! Now all that I wanna see next is domination of Core 2. If second thoughts, i7. I wonder if they got plans on lowering the Voltage and Multipliers? Cause this could have no boundaries with overclocking as Phenom hogs so much that 100-200MHz increases result in the CPU using a whopping 15-20 watts more due to the L3 cache and the fast FSB. btarunr should look for game benchmarks, at least F.E.A.R. but I think that 3DMark test proves that AMD is making a comeback with what will soon be Intel's legacy products. Will most likely beat Core 2 however not i7. Be aware however that AM2+ will probably get a makeover like 775.

they might just beat Nehlem with this anyway, this is intels first step into the IMC realm and it could cause serious issues. We already have intials reports of higher TDP than the penyrn systems, and this will translate into lower overclocks. Also with the bus speed of the intel right now the IMC won't offer the same advantage that it did for AMD. Remember AMD went from 400mhz to 800mhz overnight but going to 1000mhz HT didnt yeild alot nor has the 3600mhz HT yeilded signifcant advantage for Phenom over the normal 1000mhz HT of AM2 boards. So I hope Intel has more than an IMC up there sleeve.

Another Chinese team reached a "huuuuuuge"-er OC of 3.60 GHz while staying within the 120W envelope. I doubt you'd need extreme cooling for that TDP though I don't recall what they used to cool.

I think they used the same PC-Cooler HP-1204X, didn't they? It's hard to keep track.

Maybe this is AMDs 3870/50! Make the previous thing a little better and more efficient while doing something totally badass in the background.

It's funny you should say that... http://news.softpedia.com/news/AMD-Unleashes-Hydra-8-Core-Competition-for-Nehalems-84982.shtml
Deneb is really only a placeholder - but a good placeholder!

 

[candle_86]

Yes bulldozer, the AMD K10 its a little late, it was supposed to arrive in 06

 

[OzzmanFloyd120]

Hmm, I may have a 9550 and 9850 for sale soon!

 

[cdawall]

maybe this will mean consumer grade dualie boards 2x phenom 45nm to compete with C2Qs?

 

[kaneda]

You are right, but K8 is somewhat good architecture as without it AMD probably won't be the first to have L3 cache. Intel is taunting the $** out of AMD now that they has L3 cache in their Larrabee CPUs (i7). In the consumer market this CPU will definitely be on demand since Phenom is almost legendary in video playback performance, which will give AMD a little more profit in their pocket to finally kick K8 out the door with some good ol' engineering. Even though K8 is still on the crapper in the AMD building, the fast FSB provides excelling media and vista performance for the basic budget user and casual gamer.

I was under the impression Nehalem was i7 not Larrabee.

 

[btarunr]

Even though they achieved a cooler and low power consumption phenom, it really isn't worth a try. So they didn't increase the instruction set then. Its still the aged K8 architecture. what the heck? I was hoping this will compete with Nehalem.:shadedshu

It still is K8.....K10 to be technical. Well, comparing Intel's 65nm quads to 45nm quads, SSE4 was added to the 45nm ones. AMD has had SSE4 since 65nm. But SSE4 isn't a big issue. AMD Bulldozer comes later (but I wish they rush it in).

 

[OzzmanFloyd120]

This makes me feel like a noob, but what is "AMD Bulldozer"?
Am I right assuming it's the hype-name for their next architecture?

 

[candle_86]

yes, its what the K10 was supposed to be actully, it was supposed to replace the AMD64 and it started getting talked about back before dual cores even showed up.

the current form, in wiki form to read

Bulldozer is supposed to be AMD's 'true' next gen over K8/K10. It's expected to be an architecture change as drastic as the change from K7 to K8. AMD's best kept secret about what exactly goes into making it.

From what I remember all 48xx series cards showed 480 stream processors before W1zzard changed it in GPU-Z. It's quite possible those Chinese sites had the card. Either way leaks and rumors should always be taken with a grain of salt.

But one can hope though, right?

 

[laszlo]

nice but intel is ahead with the tri-gate transistor;amd can't catch up with soi;i think without oc these aren't better then latest quads they have managed to solve the power leakage what was the cause of the high power consumption

1. Power Consumption testing is something people do using instruments, not benchmarking software, so it doesn't have anything to do with a CPU's arch.

2. If you don't trust the Chinese, prepare not to trust CPU-Z, CPUID SDK and its creators as well, the primary specs are put up in those CPU-Z windows.

With all the bull that was spurt out before Phenom was released, hope is a tough pill to swallow, I wait for facts. Believe me, I lost a lot of money with AMD stock thinking Phenom was going to be something great. I truly do hope that AMD's new archetecture will be great and bring better competition back with Intel (and pick up thier stock prices). Time and facts are the only two things that will reveal the truth.

I know what you mean about being disappointed with the Phenom, but I did a clock vs clock of my BE vs a buddy's Q66 and the gap wasn't as big as I figured it would be. Super Pi was the only place where the Q66 smashed my Phenom.
I feel safe saying that by my tests that AMD really isn't really all that far behind Intel (with the exception of OCability of course, but I don't think that matters all that much considering only ~10% of PC users overclock their hardware.)

But that 10% talk too much

Like you said, I am absolutely happy with my Quad after disabling the TLB patch. I just wanted AMD to release a killer CPU and get back in the race.

 

[candle_86]

the truth is the E4xxx and E2xxx line of CPU's lost to the X2 CPU's alot, on a price vs preformance standpoint, untill OC'd the x2 at the same price was a better buy. This has changed though the E7xxx but the Tri Core Phenoms are helping to alleivate some of that strain, as more apps become multi threaded the Tri-Core becomes a better buy. Intel though wins because of marketing, they won in the P4 era for this very same reason. The Athlon got very little show, and did not outsell, and it never has. If AMD wants to compete they have to market it very aggressive.

 

[Mussels]

AMD and intel are fairly even in the STOCK comparison, its just that intels OC'd so high that in the enthusiast market they never had a chance.

most stock users look up reviews, hear a chip was a 'great clocker' have no idea what it means and buy it anyway.
