AMD - Bulldozer Chitchat

[watercooled]

The current 2-chip chipset isn't helping power consumption either - I mean kudos for preserving the platform but I imagine a new platform (Trinity?) would make quite a difference.

Ahahaha, that was not only funny, it expressed my opinions near enough to the point.

I especially liked the references to other famous Hitler videos ^_^

So Although these chips will run on am3+ boards the piledriver chips wont?

[EvanJackPenn]

The next set of FX CPUs are the last to run on AM3+, methinks.

Methinks they need to get these out as quick as possible,but if the BD issues with Windows 7 scheduling persist I am now not so sure ATM.

Glad I did not wait.

Well i`ve been without a pc for a few months now waiting for this and feel a little let down. The fact that I`d probably have to upgrade the mobo anyway when the better chips comes out is making me think I might as well go Sandy bridge way

Yo dude. Yes i know 12 core opterons are good value for money at HPC. I am thinking 8 pretend sharedy core bulldozer wont be as good. We will see though i suppose!!

I am updating the guide so if you want any suggestions,you could have gander at it. If you are gaming a Core i5 2500K makes the most sense ATM,and hopefully Ivy Bridge will make it to many motheboards too.

ATM,it would be a shame to have to drop the Phenom II X4 and the Athlon II X3 from the cheaper build alternatives at the beginning of next year. However,it does look this way though and the young whippersnapper FX4100 looks rather malnourished.

They are using the Intelagos based ones according to the article. So that will mean 6,8 and probably 16 core(MCM) versions. According to some articles they will be using 38,400 16-core AMD Opteron 6200 series CPUs.

My use seems to be changing a lot.

Gaming is important but more image manipulation and programming than before.

I`ll have a gander at your guide when its up. Already have my graphics card which has been sitting in the cupboard for past 2 months getting dusty lol(PowerColor Radeon HD 6950 2GB PCS++)

[Noxvayl]

How dare you leave a card like that in your cupboard!?

I agree with mr moose, the i5 2500k is top dog for gaming but it also manages other tasks admirably. It does everything much better than my current CPU so will be a very good upgrade for me

What a let down these CPUs are

I don't think this in anyway takes into account the cache or FPU layout of the chip though.

The Anandtech write up of the scheduling issue makes it fairly clear that threads that depend on each other for data will run more efficiently if scheduled on the same module: don't forget that each module has two complete integer cores with a shared L2 cache, so if the data from one thread can go into that L2 cache then be picked up by the second thread from L2 cache that's a big saving on trips out to L3 cache (with increased clock cycle latency on BD) or main memory. Also, the increased clock speed available due to gating idle cores not only pushes more instructions through but also helps to mask the higher cache latencies...

As to the FPU layout, as far as I can tell BD has no more FPU capacity than a 4 core Phenom II for a lot of floating point workloads. It needs code that is heavily optimised to really shine. It is, sadly, in many ways a processor that is ahead of its time in relation to the software environment it finds itself in. On the plus side, the fact that Microsoft have already written a scheduler that is better optimised towards BD suggests (I'm making wild assumptions here, btw, feel free to correct me ) that it might be possible to provide either a patch or a kernal mode driver that will allow Windows 7 to make the same optimisations, so we could see those scheduler-related performance boosts sooner rather than later...

HAHAHA IT WAS SUPPOSED TO BE A HORSE, A BULL IN FACT,,,

LET IT BE KNOWN AS.... girbilDOZER

I LIKE AMD BUT HEY, AN APU COULD NEVER RIVAL AN ENTHUSIAST CPU+GPU. ITS A STREAM CPU THAT DOENST REALLY STREAM VERY MUCH!!
