Default Re: Official AMD FX Bulldozer review thread!

I'm trying to figure out how this even happened. Looking at a 6 core Phenom II in terms of size/transistor count/performance, and looking at the improved version that was on the A series Fusion products(5-7% per clock faster) , this just seems impossible.

BD is almost 2 billion transistors and 315mm2 on 32nm.
Phenom II is only 907 million transistors and 346mm2 on 45nm.

If they just took the improved A series Phenom core, and put 8 of them on a chip, you'd end up with around 1.2 billion transistors and a die size of around 240mm2 on 32nm, with much better performance than this chip. They could have clocked it up faster because of the power savings. Why didn't they just do that? They've been making this thing for like 4 years, and it ends up worse than just a macro'd die shrink of their existing processor? I don't even understand how that can happen.

What a let down. I was expecting close to 2500k performance. It's not even in the same league. I can only imagine what my chip at 4.7 would do to one of these things.

I'm an Intel guy through and through right now, but I swear a small part of me died inside after reading some of these reviews this morning. I have very fond memories of the AMD K6-2s, 64s etc.

i think it would be better if they would never release this thing.

After reading a bunch of reviews, it's apparent that Bulldozer is ahead of it's time; in most modern applications that use multiple threads and newer extensions, the FX 8150 beats the 2500k, and some times the 2600k. That doesn't help us though. As of now, the CPU is slow compared to the competition in applications today, and for that reason, AMD really has no excuse.

I think if this CPU had come out about 3 or 4 years down the road on a smaller node and higher frequency, we would have seen it be competitive. As of now, Bulldozer has a serious identity crisis on its hands.

I am very disappointed that apparently the performance in
  • Single-core
  • not simd, not floating point
  • not recompiled every time you get a new CPU

has actually gone down. I mean WTF. I spend a lot of time in single-threaded non-media things, just starting from linking large C++ programs.

The only good thing I can see is that at least price/performance has been picked so that the price for the same performance if you do use all cores is still better. I still expect to have a dual socket system with registered RAM with Bulldozer as my next virtualization system. But ... meh.

To be honest this isn't surprising. A leaked and now pulled test of Intel's next socket's system had about the same power consumption when overclocked.

I think those of us who run clocks of our choice will have to change our way of thinking, namely if we want to run all cores at full power AND overclock at the same time then we'll have to get a lot of energy in and out.

Which kinda sucks since the manufacturers give us no interface to do variable overclocking by how many core's worth of CPU work I have there. They do this in their own implementations of Turbo but they don't give us the same tools.

have you seen this?

clock for clock, core for core, the new design is horrible

Yep, disappointing. I wasn't planning on buying until next year now but I kinda doubt whatever I buy will be AMD.

What a fail.....a horrible fail....there are no words to express the depth of AMD's colossal blunder.

Won't buy it...can't see anyone else buying it.

Pricing is going to have be very competitive very quickly. Anandtech said that it might have a place in server land but I seriously doubt it at those power and heat levels. Also, who wants to virtualize across two platforms?
