[AMDblog] Our Take on AMD FX - Page 22  

post #211 of 231
In some ways I feel bad for JF-AMD and in other ways I don't. I think his intentions were good. I asked once why no one who worked on the client (bulldozer side) posted here and he indicated they would be overwhelmed by the amount of PMs and angry E-mails given the amount he received while he was representing the server side and just giving us information about Bulldozer. He did spend a good amount of time posting and answering questions, and for that, we should be grateful. On a side note, is there and Intel guy on here? Anyway, what is bad is JF-AMD saying that IPC would be higher. Given some past architectures, it could be argued that server stuff is different from consumer stuff. However, JF himself said they are the same cores, so he should have known better. However, again, there's probably some workloads where the new architecture shows higher IPC, but that's a real stretch.

From the get-go, all the secrecy about Bulldozer performance and lack of any benchmarks from AMD scared me. Now I know why. I think the prediction I made in my signature was fairly close, but probably actually too high of performance.

Just because someone works for AMD, or Intel, or whatever, doesn't necessarily mean they know all the details about their products, or that they can accurately infer wider performance based on the details they do know. This is especially true of areas outside ones expertise.
His posts were very matter of fact and I don't really buy that he didn't know all the details about Bulldozer. Certainly would have known what the benchmarks were like.

None of us will ever know how deep the Bulldozer story really goes. How long they knew about lackluster benchmarks, power draw, etc, etc, etc., but I'll bet for a looooong time.

There's a good reason they were doing all the BS marketing tactics for months now like overclocking competitions with no benchmarks, etc.

If your chip is stable enough of a production model to hit 8.4 GHz on liquid helium, surely you'd run CineBench to show us how badass it is (assuming it is badass at all which this isn't).

I know AMD takes this stance of "NO BENCHMARKS BEFORE LAUNCH" and all that crap, but they made an exception for Athlon 64 X2...know why? The benchmarks were fantastic! This rule is truly only in place as long as their CPUs are performing at subpar levels.

Did anyone see the latest blog post?

"Sorry, we meant a 2500k, not a 980x!".

Great, so an 8-core chip clocked higher can barely beat a 4 core chip without hyperthreading??

That is really the best they can say about their top of the line chips:

Nothing to get your blood pressure up over. This is clearly a marketing move.

Review sites have acknowledged that they AMD knew for months that the 8150 would "compete" with only the 2500k, and then only in certain benches. I didn't care that they didn't leak benches; what scared me was the constant delays. They did the same thing with the 69xx GPU line when nvidia suddenly launched the 500 series and kicked them in the teeth.

I hope that, like nvidia did with Fermi, they can take an okay product with bad power draw, improve it with a tock refresh, and become a real challenge to Intel.

Thats asking a lot considering each company's size. Ive said this over and over, but I think its amazing that Zambezi accomplished the performance that it did given everything stacked up against it. There are so many factors limiting its performance, and that it can keep up with a 2500K and 2600K in some tasks, which were themselves amazing chips when they came out (and still are) is a good feat. Not to say that I would recommend buying it, just looking at it a different way. Zambezi is, in my opinion, more of a stepping stone, and it will be interesting to see what they can do now that they got the hard part out of the way.

In a lot of ways, it parallels Pentium 4. It did a lot of things at once, which ended up with a lot of things that were not implemented well. Intel went back and slowly implemented things from Pentium 4 to newer chips, but better. The difference here is the Bulldozer design CAN'T be implemented over time. Its all or nothing.

Except the 69xx series isn't inferior....

Err, the 580 is almost $500.....the 6970 is under $350.....I don't know what you are trying to compare here.

What?
YOU are the one that started the comparison. In absolute performance, the 580 is the strongest single GPU.

Exactly, if the 6970 was superior it wouldn't cost the same as a 570, and the 580 wouldn't be $500.

Let's keep this discussion on AMD FX, and AMD's take on the whole thing.
