The newest fleet of quad-core desktop processors from AMD, the Deneb series is tested by Chinese website Zol to consume up to 12 per cent less power compared to equally clocked 65nm Agena parts, add to that, the fact that the 45nm Deneb comes with three times the amount of L3 cache, 6 MB.
The 45nm and 65nm parts were compared on a MSI K9A2 Platinum motherboard with a NVIDIA GeForce GTX 280 card, a single 320 GB HDD, two modules of 1GB DDR2 1066 MHz memory, the test-bed was powered by a Thermaltake Toughpower 1200W PSU. Power consumption was calculated in idle and load (the CPUs were stressed using instances of Orthos).
In idle, the 45nm CPU-based system's power consumption was measured to be 147W compared 154W of the 65nm CPU-based setup. In load, the margin increased with the 45nm CPU-based system running at 176W compared to 200W of the 65nm CPU-based setup.

nice, i hope they will be faster than current amd processors
yeah it's faster than the current ones, but we don't know yet if it can compete with current intels.
but 12% less would mean that the 2.6GHZ variant would consume 124watts vs 140 on the 9950 0r 110w for the 2.5GHZ one vs 125w on the 9850. not great but better.

Assuming this allows them to unlock higher speeds AMD may finally have a chance.
Wasn't these processors tested with the same cpu voltage, 1,224V i think i read somewhere. If so the new 45nm processor still consumes less power even tho it shouldnt need that much voltage to operate at the same GHz. I guess it can only get better when the voltage is dropped yes?
Yes, they do seem to OC well. Some unlocked multipler based chips did 3.60 ~ 3.80 GHz in some beds by Chinese websites.
I'm hoping they'll make a dent, but it's more likely to be a scratch. Looking forward to some reviews.
by: yogurt_21;897791The 12% reduction was in the overall system power consumption. That means the reduction in the CPU's TDP is more than 12%.

Wasn't it a similar case with Phenom's?
by: btarunr;897794good AMD can finally catch up. its a little sad seeing rigs which cost more than mine powered by AMD CPU's, that even massively OC'd (3.2GHz+) just cant touch mine due to the CPU holding everything else back.

its good that they use less power AND have more cache. speed wasnt compromised.
by: xfire;897837Huh? 45nm Deneb core will be sold as Phenom X4.
Wasn't it a similar case with Phenom's?
Hmm, interesting. This might solve their overclocking problem if they put in a lower voltage core, due to their power consumption. Therefore less heat. Anyway, since the biggest siblings of today's Phenom line like the 9850BE consumes about 125W, the 45nm line will replace the 9850 with the power consumption of about 110W, which is 1W more than the Q6600. This could be a big step if AMD really makes their mark, especially when the Phenom line truly has four cores, while Intel quads like the Q6600 has two dual-cores linked together.

What I meant was that the samples of phenom's overclocked well too but the final product didn't.

Your nubmers are wrong, as well AMD doesnt do TDP any more, they use a different method
I'm holding out for these processors. Not expecting them to do anything magical aginst intel's nahelem, MAYBE compete but more on a price/performace field. I just want a quad that isn't going to melt my 780G mobo and still has a decent clock speed (2.6+ hopefully)
This isnt going to blow intel away. That day will come with the G34 socket that AMD is designing.
by: Viscarious;897921remember that youre aiming at a moving target.

.... with nothing more than a bb-gun.
i just continue your phrase. don't take me the wrong way i like amd but it seems far from performance competition with intel:toast:
I'll probably get one when they come out, I haven't had Intel in my rig since the 233MHz P2 and I'm totally still not getting one :P
Im fairly certain the G34 will surprise us. But you are right too. Its only a blueprint we've seen with very few details on production, however, I have strong faith with AMD on this one. I mean cmon! Its code named 'Bulldozer'!
Hope its not a load of bull*steaming pie*
by: yogurt_21;897791124W still isn't something I'd put in my PC. Besides it says "up to", so on average the gain is lower.

124W is a lot and if amd want to capture market share they need to get out lower power quads
i think that the low power new x2s are a great start but really they need low power quads too even then it should only be double the power of the low power x2s
since amd do everything now from cpu graphics to the south and north chips on mobos i think the plan was it would be cheap for the customer and allow amd to get better performance still didnt work that way

fantastic, im gonna hold out for one of these instead of a phenom X4 if the price is right (the test rig there using is my board so no problems there ;)), will go nice with the rest of my rig when i get a 2nd 4850 :toast:
btw anyone else think that psu was a tad bit overkill 1200w and why the hell with a gtx 280 on an amd crossfire board :shadedshu

it's looking like AMD will defi have something to offer in the near future -
even if it doesn't go over too well in the retail market, Deneb is starting to look like it'd be mighty appealing to OE manufacturers, especially if the CPU also performs quite well at stock speeds.

Check out this nifty feature AMD pulled out of their ass http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3360&p=1
The NB actually clocks higher! Can I quit complaining? Only benchies can do that.

by: Yokozuna;897834true, it consums 24W less so tdp should be 100w instead 125W that is abaut 20% less
The 12% reduction was in the overall system power consumption. That means the reduction in the CPU's TDP is more than 12%.
even more impressive, i feel stupid for not realising that :P

124W still isn't something I'd put in my PC. Besides it says "up to", so on average the gain is lower.
How about this: these chips feature IMC (memory controllers) that apart from adding to the CPU's overall power load, also fuel the memory modules?
AMD chipsets (both by AMD and NVIDIA) consume less power compared to their Intel counterparts (chipsets by NVIDIA and Intel), so much so that the same desktop chipsets by AMD make it to laptops. So the difference between a Phenom and Intel Quad in terms of CPU consumption is shadowed by the fact that the lower power consumption of Intel CPUs is marred by higher consumption of the MCH chips (northbridge).
yes it is true, so u must always lok for total power consumption of system under load
So 125W you wouldnt put in your pc, but the older p4 architecture hit that did it not?
Lower power is always better for my utility bills. I hope these clock well. I may wait on these instead of a 9850BE :D`

Does anyone know when these CPU's are going to get released? And how much will they cost?
I am planning on buying a new PC at the end of august and I would love to go back to AMD, if these CPU's are decent offcourse.

I may have to wait and get one of these instead of the Phenom i was going to get.

I think you are wrong. The G34 is not a Bulldozer. The Bulldozer is a new architecture from AMD. It is 8-16 core and 8-16 threads. It has quad G3MX memory control , it's a fusion cpu with GPU+ CPU side by side on the same die.It also have SSE5 instruction set and a new 170 instruction set.This will be a fast single thread.Sandtiger compete win the server and enterprise market.Bulldozer wiill be in desktop.This bulldozer to be 3X the performance of the shanghai.
by: WarEagleAU;899315not sure where it hit, but i had a P4 weld itself to the heatsink, and no im not exageration here

at last , amd is back
by: hayder.master;902952Lol, they are not.
at last , amd is back
The AMD 45nm Deneb will finally be able to compete with the Intel Q-series. But don't forget that Intel will release their next-gen CPU's only a month or two after AMD Deneb release.
They are not back, they are seriously behind...
by: btarunr;898881It is completely irrelevant where the power goes. Fact is it is a single small chip from where you have to move heat away. According to your logic putting a GPU and CPU on a single die and have some 300W monster is good "because it also has the GPU". The only relevant thing there is that it is near impossible to move away 300W from a single small die, no matter what tasks it fulfills.

I'd rather have two chips.
But then energy spent on the machine remains the same, right? As also the machine's total heat generated? It's not like the stock coolers AMD supplies with these 125W chips can't keep them reasonably cool.
This does look promising; however i have a question:
If say you wanted to sacrifice this energy saving could you not just pump some voltage through it to get to a higher clock - providing cooling is ok?
