No. We don't know anything about the size of the core. Please stop spreading this fud. Keller only said it will be a high performance core. So, it's likely not a small core compared to other small...

I don't think so. They failed once with that very hard (Larrabee). Even their process advantage couldn't save them. CPU for graphics is just too inefficient. So, the "long-term goal" is already...

Well, at least you can give credit to Intel for widening the pipeline to 256-bit and a new coding scheme. The instructions itself are quite similar, of course. OTOH, Intel64 was indeed just a renamed...

Well, the LuxMark scores actually look quite odd. According to the specs the old Haswell shouldn't be much faster than Broadwell. Or something strange is happening with Broadwell. Anyway, even if...

Actually Cyclone has a quite decent FPU. SoCs like Nvidia's Denver indeed have a terrible FPU.

Carrizo (Excavator) introduces AVX2 on AMD processors. But I doubt it has any impact on SiSoftware's processor arithmetic.

Then they probably have a different implementation with separate execution logic. That may be one reason why Haswell can heat up significantly under AVX workloads.

You seem to have a strange sense of humor. Sarcasm is actually not meant to be funny. But if it helps to understand your mistake I can live with it.

Which is actually normal due to the FMA implementation. I think this is not a problem at the moment. The Bulldozer pipeline can hide instruction latency quite well. Maybe it would be a problem if IPC...

But that would mean Intel has an HBM design in the work for quite some time, right? I don't think that's the case. And they can't do such a design in just one year or so. I guess Intel will use HMC...

No, it isn't. And you know it. Your claimed 100% is wrong if you didn't talk about Cortex-A72.

It is, if you are willing to trade some efficiency for more performance. Efficiency is not the most important metric for consoles.

No one talked about such a wide design. But a 4 GHz 2-way OoO design definitely makes less sense compared to let's say a 2.5-3 GHz 4-way OoO design.


The reason is performance. Steamroller can...

You are aware that Cortex-A72 isn't even close being used in any product? Cortex-A57 remains the baseline for ARM throughout 2015.

And btw, as licensee AMD can use Cortex-A72 if they want. But I...

I doubt that. And I also hope AMD won't design a CPU just for AAA games.


Then SB-E is just a "broadly copy" of the PS4/XBO architecture, right? I mean it has 8 discrete cores too.

Either you copy something or you make something more powerful. Both at the same time is not possible.
