Even if one calls the performance similar to Sandy Bridge, the power draw is absurd. If I'm going to upgrade my PC, I don't want to go the route that will cost me more perpetually.

yea die shrink, maybe 3d transistors. lets face it, they had five years to do it. that means they couldve spent two years at the drawing board, and three years completing the task. not sure what happened.

amd will not suffer greatly though as much as some of us would want, and who knows, the enthusiast is a very small portion of the consumers. with them pushing the "8 Cores" may do really well on the market. in which case everybody benefits.

amd meets their quota, the 7*** series comes in shortly after. intel sees the competition steeling sales and lowers prices, and hopfully releases Ivy without too much delay.

everybody wins.

I dunno, looks decent enough for a 200 dollar processor. I'm really not that enthused about the power usage numbers so far though. The quad core version is the one I'll be looking for, and the price for that will be really decent. No need what so ever for 8 cores in my homestead, had to throw in my pennies =P

yea i saw them,why then did say to everyone that BD will be great,trust me guys my cousin sent me graphs?those graphs show BD x8 barely trading blows with the i7-2500K quad core?
my point still stands,two months ago when you saw these graphs why didnt you go with SB?you knew the rumors of BD costing more than a 2500K already?i just dont get it?maybe you dont know how to evaluate graphs?

That would be nice. Sucks we have to put all our hopes in the ignorant masses though...

Well, goodbye AMD

After 20 years of beeing fanatic AMD fan i feel cheated. When prices here where i live was really low they bombarded whole world with screens and bars showing it will compete with 2600k and even 990X so i waited. Now prices are really high because of strong $ Now if i want to buy 2600k i must pay 150$ more for it !. More about it. Time to stop selling AMD platforms. Im not angry about all of this just thank you AMD to show me how are u treating yours long time customers) And in now days power bills. No way AMD.

Yes my english is bad

Well everyone was (should have been) ignorant till today, with the exception of AMD and a handful of people. Claiming otherwise is a lie.

Still extremely disappointing. The worst part is AMD and its "marketing" of this chip like the second coming. Almost as bad as Apple can be, shame on AMD.

That's what I think aswell.

APU approach was designed for a world were GPUs come into play during real world tasks, not in a world where the GPU is merely reserved to extensive vector-based apps or gaming.


AMD thinks forward. Almost too forward. If they hadn't dropped as much 'old tech' in this new architecture, it'd performed like a boss. But who tells you that in a year Windows 8 comes up with 'god-knows-what-multitasking-improvement' and the Bulldozer/Bulldozer II trounces and tears thru the competence?


We, sincerely, don't know.

Ok. Cool. So what percentage of buildings use wind and solar?
Let's not for get how expensive those forms of energy are in themselves but I digress. BD fails on every level no matter how people try to spin it.

The chip was launched too early. I think that two performance increases are coming. The first will be piledriver. I suspect (given that it is launching in just a few months) that AMD pushed out this chip knowing that it had problems. I further suspect that the biggest problem is the one thing AMD won't talk about: branch prediction. Anand's N x N queen simulation helps to show that branch prediction has taken a large step backwards. Given that branch prediction is even more important with a longer pipeline, this is one of the most likely culprits. I believe that piledriver will focus almost entirely on fixing this problem.

The second problem is GF. AMD planned on a base frequency 30% faster and only achieved 9% faster. Even with the problems the chip has, overclock benchmarks @4.6Ghz (about 30% faster) places the chip more where it should be (at stock). In the upcoming revisions I think that speedbumps of 200Mhz+ are likely. Part of the cache latency problem is also linked to poor fab yields (increasing cache latency can help improve yields) and I suspect that piledriver will also have cache latencies more along the lines of Phenom II (or maybe just a bit faster).

All this said, this chip's intended audience was never primarily consumers. I think that server benchmarks show this chip to be more than competitive with sandy bridge.

OT edit: I think that with the BD transistor budget, AMD should have done what IBM did with POWER7 and made the L3 cache eDRAM (IBM did this to put more in while using less die space) and forgoing L3 for consumer chips because L3 is primarily to help with multi-processor bottlenecking in server/HPC environments.
