From the CUDA thread, it's clear that they added some kind of register reuse cache that reduced register fetches from the register banks. Banks are pretty large, so that should result in quite an...

They bother me on every website, but I never see them on Intel because I never go there. I do go equally often to Nvidia, and I've never noticed them there...

Ah, yes, that's the one I was whining about. It seems to pop up with surprisingly high frequency.

I didn't get it either, but I routinely get one of those tacky 'please rate our website' pop-ups. They only reinforce the ugliness of the AMD site.

I don't understand the hostility towards FP16: it's obvious that it will consume less power and it thus makes total sense to advocate its usage. And given enough incentives (read: FP16 is faster than...

Are you sure about that? I thought MXM modules had the DRAMs in the module itself. It'd be madness to route a fast DRAM bus through such a connector.

Edit: a google for MXM shows DRAMs on the...

The area cost of the secure element is probably a small fraction of a mm2. Probably not much more than a bunch of side band signals and registers between fuses and encryption blocks that can't be...

Very low?

Even if they expected high demand, there's only so much they could have done.

Yes, it's just too early to judge Read's tenure. How many new chips can you really think up, design, and bring to market in such a short time?

It's still a very open-ended question if, eg, the ARM...

Silicon didn't get cheaper. Average die sizes went up. AMD got wiser about pricing themselves into the bargain bin category? (Finally one thing where they're doing something right.)

That would only work with pretty large cache lines, otherwise there wouldn't be any compression. But larger cache lines can be inefficient if you only use a small part of the data.

Why would it be less efficient for compute? Nvidia claims that the SMs saw a 2x efficiency increase, which is what gets hammered the hardest in compute.

With 4 HBM stacks, you're looking at 512GB/s vs 7GHz x 512/8 = 448GB/s if you'd use conventional GDDR5. Doesn't that make it a bit pointless? I understand that there are some power savings, but they...
