A report on DailyTech has suggested that there is more to AMD's tri-core Phenom processors than you would have first thought...

wait.. what?

steveo_mcg · 4th Dec 2007, 12:04

I suppose it'll clear up closer to release time but.. wtf??

The tri-core chips might be a completely different chip to the current quad-core Phenoms, but then there are other things which point to it being the same chip. It introduces a shed load of questions about what all of these codenames are for.

DXR_13KE · 4th Dec 2007, 12:33

wait... i got it..... "more than meats the eye", they are transformers and the code names are their real names......

They may well run out of integers for model names if this is the case.

Redbeaver · 4th Dec 2007, 13:46

rofl.... yeah transformers...

tbh im with these guys' boat... have no clue. EXCEPT i now understand AMD's 45nm quad-core with shared L3 = Deneb. thats all i need to know lol.

These products will fit under the Phenom 8000 umbrella and, according to DailyTech, the first processors to be released will be the 2.4GHz Phenom 8700 and the 2.3GHz Phenom 8600. Anonymous AMD representatives said that both of these will launch with a 95W thermal envelope.

wait, AMD's newly developed 3 core CPU uses the same amount of power as my over 2 month old 4 core CPU??

god, AMD, do try to keep up

steveo_mcg · 4th Dec 2007, 16:14

Not being funny, but does intel still use a north bridge for the memory controller? If so then of course the AMD cpu power consumption is going to be higher... the intel chip simply off loads some of the heat to a separate chip

As Steveo mentions, the north bridge uses considerably less power on an AMD platform than it does on an Intel platform because the biggest heat-generator (the Memory Controller) is inside the CPU. Also, don't directly compare TDPs - Intel uses 'typical' and AMD uses TDP-max.

So the processors will have the cores on them but just disabled, I don't get it - why? Surely its a bit of a waste if they are there...

Presumably initial stock at least will be processors which have come out of the manufacturing process with a fault on one core, so they disable that faulty one and sell it at a reduced price.

So they can sell off faulty quad core chips as a dual or triple core chips rather than binning them, but then i dont know how the triple core chips can have ddr2/3 support when quad core chips only have ddr3. so... ???

ssj12 · 4th Dec 2007, 18:13

so from what I can tell... AMD is releasing these by the time that the QX6850 will be around $500 USD.. honestly not to impressed by AMD's planning. Figured they would release something stronger asap.

kenco_uk · 4th Dec 2007, 22:59

Is it Tri-Core because there'll be effectively three different cores on one chip?

Tbh, it sounds like a pretty mean feat of engineering.

Woodstock · 5th Dec 2007, 00:31

tri-core is a we can do this but intel cant
