Am i the only one who is NOT surprised?

they gonna lose to intel seriously
my beloved AMD jus reli hope they can do somthing to cheer up AMD fans

but they always delay it and makes no point....
really fedup...

I am not surprised as well
Judging from the poor clock scaling, i believe there is some flaws in their 65nm ramp up (although AMD keeps saying no problem). Besides, there might be due to low yield rate.

not rili, and pray that it wont happen. from the info that have been surfaced, barcelona will match intel current core processor. as for the claim by AMD that barcelona will outperform core by 20% or more, i seriously doubt that . but barcelona power consumption and its feature may post a shock to us.

there's no way you can make substantial changes to your marchitecture in less than half a year, so don't count on it. Core2 was not started after Core was finished, else they would have never completed it so fast. Intel has more resources to have more concurrent development teams.

not suprised. more like expecting it
afterall, ATi has infected AMD with their delay sickness.

Hope it's not true...

Terrible news... but did AMD said to reuters that we can expect a demo somewhere around july? btw, read this another malaysian news website regarding barcy updates, its been well circulated in many forums.. http://xpentor.com/mamboserver/index.php?o...id=516&Itemid=1

BTW, i'm a newbie to this forum, XD

I dont know how they got themselves into such a mess At 1st I thought Barcelona would actually be good but this confirms to me that its gonna be just another R600. And Penryn will be launching like what.....a month or 2 later? Anyway I hope they get their act together coz having an Intel-Nvidia monopoly would definitely harm us consumers in the end

Anandtech wrote up something. The poor performance might be due to immature BIOS implementations. My guess wasnt wrong too, the clock scaling is not up to expectation and AMD might delay Barcelona launch.

here is the whole story

That anand article looks suspect to me... performance doesn't scale exponentially with clockspeed lol

if performance does scale exponentially with clockspeed, i will consider LN2. really!

anyway, this time DAMMIT seem like in big mess. everything seem like didn't work out for them. even accusing intel of being unfair when there is a fair competition anyway?

i thought it was intel who accused amd for being unfair comparing barcelona with clovertown

I guess the performance lost might b due to poor memory utilization by the BIOS (max of DDR2-667 and timing might not b good). It is a miracle if BIOS could make the CPU performance scale exponentially with clock speed LOL.

Assuming performance is not where it should be, my guess is that some things are still not working right and they had to microcode the fixes which makes it really slow.

Maybe it is some pre-fetchers problem, since they are new.
Besides this, maybe the performance is not up to expectations in single thread applications due to small L2 caches and 3 issue core. Intel has an absolute advantage when it comes to cache and prefetching.

I'm surprised that they did not show any encoding benchmarks which should show the largest gains due to SSE128. Looking at die shots, the additional 64bit of the SSE/FP engine seems to be "tacked on" to the existing K8. Doesn't seem to have major changes to the layout per core. So that could be broken, and if the original SSE/FP engine is working they might just have made temporary fixes (to this and a few other things) via microcode, which is why performance isn't so hot, and they can't really show encoding benchmarks because it will look crappy.

Cinebench (which DT ran) is hardly a single threaded app. It scales well up to 16 cores or so.
