Phenom FX in the Works, AMD to take Another shot at...Kentsfield

[Melvis]

Some AM2 boards can take Quads, it depends on the size of the BIOS chip the manufacturer put on the board, and whether or not they choose to support it.

As for my board, it's a DFI NF UltraII M2. They aren't supporting Phenom on it. Don't know if it's a bios limitation, or their choice tho.

Hmm ok fair enough, gotta suck tho =/ Iam hearing alot of people having problems with that brand, like the 4870x2 not running properly in them =/

the Kentsfield is also higher clocked, and overclocks almost 100%.. :\

Here, have a read of this, it will explain it better than I can...............

I meant at the same clock speeds.

 

[Bluefox1115]

I can honestly see an amd quad core 45nm at 2.8 to 3.0 ghz stock running in the 30 to 40 degree mark on idle. and at 3.5? 50C tops with decent cooling. isnt amd updating the coolers as well, for the new chips? they are going to be more effective and not just a hunk of aluminum,?

 

[Bluefox1115]

yea. Intel has been shown to beat AMD at stock speeds as well.. about 200 to 400mhz wise in actual speed difference.

 

[Melvis]

Do you not think that AMD would bolt on extra L2 memory if it would bolster their performance to any degree?.....of course they would, it would pay for itself in a month because so many more people would buy AMD if they were competative....no, as I said, the architecture, unlike Intels would benefit little, AMD can swop out the L2 so much quicker than Intel so it dont need the huge amount's Intel does.

Well im sure they would, and funny enough they are goin to put a increase of cache on the CPU's, but why haven't they done this earlier? because its not that easy to do, and its very expensive to manufacture. Intel can do this and not even sneeze at it, big woop if it doesn't work as good, not like its going to hit there pockets hard, but if it does to AMD its not good at all, thats alot of money to them to waste if it doesn't do the job.

I understand what you are trying to say.. L2 cache has much better latency than L3 cache, and L1 cache has even lower latency than L2.. lower latency= higher performance. Much like RAM, 4-4-4-12 cas has lower latency and response time than 5-5-5-15.. and althought I understand your point, that post is way outdated and multiple cores with multiple caches were not taken into consideration, I would like to see an updated version of that thesis though, it's interesting.

 

[OzzmanFloyd120]

What Tatty is trying to say is that without a huge L2 cache that intel chips can't perform well whereas with AMD that much cache isn't needed because AMD had worked out a better bus than intel.

 

[Bluefox1115]

that is also true. no actual FSB, just a reference clock, and onboard memory controller.

The original subject of this thread is by far the most ridiculous pile of BS I've seen on tech forums...

 

[X1REME]

K10.5 v K10
more transistors
more pins
65nm v 45nm*
PCIe 3.0 v 2.0
HyperTransport 3.1 v HyperTransport 1/2
uses less power to run
outputs less heat
better performance
ddr3 v ddr2
much much better platform (motherboards, chipsets & SB800 coming 1/2009)
6mb L3 cache v 0mb L3 cache
2.3GHz Deneb consumes only 57.3W v 2.3ghz phenom 120/157W (4ghz = 120w approx)
Immersion lithography
4th generation of strained-silicon
new leading edge technologies??????
used low or High-K metal gate technology

This is not the DENEB FX Series they are talking about but the 3+GHz Denebs for OEM and average users.

AMD's 2007 analyst day. what a change (to counter) and hopefully better to come

No high k, nothing fancy used, get used to it that phenom is spent as far as clock rate goes.

 

[BvB123]

K10.5 v K10

6mb L3 cache v 0mb L3 cache
2.3GHz Deneb consumes only 57.3W v 2.3ghz phenom 120/157W (4ghz = 120w approx)

Bullshit

K10 = 2MB L3 Cache

2,4Ghz Phenom 9750 = TDP 95W
Deneb 2,3Ghz TDP ? no one know it.

 

[X1REME]

No high k, nothing fancy used, get used to it that phenom is spent as far as clock rate goes.

nothing fancy used. well i think 45nm is fancy enough for amd not mentioning plenty of tweaks as already said

actually nobody really knows if high k is used or not which is why i said low/high k

my mistake, yes 2mb l3 cache and as for your second, actually a few sites mention this including Chinese sites who have demoed it, and if you can be bothered to look its still there and if it was fake am sure as you know amd would have pulled it from the ears.

*sighs* 45 nm is not a clock increasing god. We're limited by the physical properties of the materials used and the exact architecture itself (K8 hello, you can make K8 smaller all you want, but it won't clock hardly any higher).

actually what you will get is more transistors which makes all the difference e.g power - higher clock (R6 vs R7 anybody)

Which is not what deneb is unless you're specifically talking cache, but we're not. It's about clock rate and phenom doesn't have it. End of story.

 

[X1REME]

the acc+ will work even better in sb800 chipsets, since amd is working towards a spider (own platform) all these little tweaks will have a massive performance boost (ht 3.1-pcie3-ddr3-sb8xx-etc)

 

[blueskynis]

Hold your horses! Please, wait until actual launch of Denebs takes place. We will wait and see what happens then...

""It's about clock rate"" by reducing to 45nm, you will get much more transistors (needs less power), more pins, more cache, better heat rate etc = higher clocks

 

[Bluefox1115]

and again.... back to my earlier post about the gap from 3.0GHz to 5GHz...

 

[X1REME]

K10.5 rev. D architecture

rev. D architecture (definitely will come earlier if they are to compete with the mighty i7)

http://news.softpedia.com/news/AMD-Unleashes-Hydra-8-Core-Competition-for-Nehalems-84982.shtml

what if these are the deneb fx (keep dreaming)

 

[X1REME]

my point: there is a few sites i checked which state the k10 is very adaptable including amd`s site and by the looks of it, they will stick to it through 2009.

AMD said they are even thinking of changing the name to k11 (which is k10/k10.5/K10.5 rev. D)
