Not when a marketing guy says it about "Bulldozer". Think of those 33% more cores, all processing instructions. ;)

The integer pipeline. That includes the loads & stores. With fp resources being widened, fp performance is taking a large jump-- what's left is the integer pipeline.

You guys apparently don't realize that:

performance != performance/clock (IPC)

IPC != single-threaded IPC

and that the Alsup statement was about the *Integer* pipeline.


It doesn't...

That statement is from AMD's ex Chief Architect. I think the guy is now retired, but if you think Intel is paying him to post on comp.arch... :rofl:

And your previous statements manage to...

What happened to power in those statements? Does performance per watt suddenly not matter? ;)

Or could it be that the adding most of a second integer core actually uses a nice chunk of power when...

Can you say, "single-threaded integer IPC will be higher than the previous generation" ?

Because that is what Alsup is saying is NOT the case. (integer performance, yes, but integer...

Indeed he did, and in the comments to that article, he explained why, and in this current article he is definitive about it. ;) informal and the rest are in gpu-shock, and don't want to look at his...

- Segmentation
- Part recovery (this should be minimal)
- The fact that adding a discrete card is doable for desktops so the IGP offered can be minimal, and perhaps the OEMs like bundling a...

Yeah, that's what Dirk said in the July CC, when it got delayed. Previously, it was "end product availability" in H1, so the fact that they needed to modify that makes one think "end product avail"...

You still trying this argument? :ROTF::ROTF:

Denial is the first stage of grief. ;)

Yes, a 4-operand form. Intel is supporting a 3-operand form starting with Haswell.

I think you meant to say, "for amd you can add several months on top of that."

Their 32nm looks like it will ship about ~18 months after Intel's, so they've been building quite a few months up...

Hopefully, the moderators won't be able to resist, either.

It's -5% IPC vs Thuban, then higher frequency due to the longer pipeline with faster pipe stages, estimated at 20-25%. This is for a single thread doing integer work.

So says AMD's ex Chief...

For specialized tasks. Haswell should be very interesting in late '12 / early '13.

I think he's making a joke. It's funny. :D

Because that is not enough time for major design changes in a new CPU architecture, and because what he describes matches up very nicely with what AMD disclosed at Hot Chips.

:confused: :confused:

Sandy Bridge LGA-2011 will come in 8- and 6-core flavors for the desktop. (in Q3)

There's a table toward the bottom of the wiki entry that may help you keep track of all...

Because responding to a post comparing BD to SB with a reminder about other SB models is off topic, right? :shakes:

Did you stop to think about how Alsup's comments on comp.arch echo AMD's slide bullet point....

Alsup: 5% loss due to u-arch trimming to meet higher frequencies
AMD: "without significant loss in...

Alsup was talking about the integer piece.

Now realize that the octal-core, 16-thread LGA-2011 competition will also be about 50% faster than the current top end, and well... nothing will have changed, relatively speaking. ;)

And AMD's ex-Chief Architect expects 5% in core level perf/clock LOSSES + 20-25% in clocks.

I wonder who will turn out to be closer? ;)

Erm, the parts that are positioned against BD (LGA-2011) have the stuff you're complaining about. :confused:

But even on these 1155 mainstream parts, even on the non-K parts, you can overclock the...

From design to launch, a modern cpu arch is about a 5 year cycle. ;)
