AMD: Speculation, Rumors, and Discussion (Archive)

if TSMC is already volume limited, they will have to compete for foundry space, and with nV being a larger partner, they will get higher priority, just like (pretty sure) Apple got higher priority than nV, which gave nV supply constrain issues initially.

 

I think the point was that AMD is using GF.

 

The one card I tested at work for this (with the same, above settings, which I found to be roughly the sweet spot) was at 135 watts (isolated, via extender etc), my own card, I haven't measured yet, since I lack the equipment at home.

 

Would be safe to buy a used miner custom 480 when vega comes out? (even if they work at full load all the time they are under volted and undercloked) or they will be just too been out to be a safe option?

 

Would IMHO depend on what they mined. An Etherium miner should be safe, apart from normal aging. A card which was abused for an ALU stressing currency not so much.
Back then when Bitcoin was still mined on GPUs, the 290X cards were pretty worn out by the time they got finally sold off on Ebay and alike. And I doubt that 16nm is more durable than 28nm was.

 

No. Morris Chang takes pride in the principle of not giving anyone priority, no matter their volume, and instead just always allowing people to bid more for earlier wafers. This is precisely why Apple wanted to get off TSMC -- even Apple cannot buy certain priority on TSMC. If AMD wants wafers on TSMC, even if TSMC is volume constrained all they need to do is to pay more than nVidia/Apple currently are to get them.

 

But RX480 is not made at TSMC, it is made at GF. This means AMD does not have to fight with Apple or NV for wafers.

 

Hmm, to be honest I was expecting closer to 100, perhaps the main culprit is the memory?

 

Well paying more will get ya higher priority lol. Supply and demand at work!

 

Maybe. There are strange correlations between memory and GPU voltage in Wattman. OTOH, there are hacked BIOSes and driver validation files that claim an improvement to ~30-31 MH/s while having 120 watts of power, though they seem to read GPU-z's GPU-only power as a basis.

 

I could post the headers, but there is this. Contrary to the last poster there, the library was available on Windows. I added this to OBGE and tried to tesselate the water, but it was't dense enough. It reinterpreted the vertex shader as domain shader. The real vertex and hull shaders were passthrough implementations. It felt very eery to programm that thing, it was like a timetravel through some wormhole, because it was basically identical to DX11.

 

That's a very nice piece of information, Etha! Maybe there are other bits hidden out there as well

 

Are the 3GB and 6GB D700s in the MacPro the only implementations of 384bit bus on Tonga? If so how do they perform compared to 256bit Tonga? Can you take the 6GB D700 out of the MacPro and put it in a Windows machine?

The 384bit bus of Tonga has always been a question for me. Not whether it exists, but why AMD never sold a part with >256bit Tonga.

 

Indeed, Tonga only exist in the iMac line-up.

And the "new" Mac Pro graphic cards do not fit in a regular PCI-Express slot.

 

Dave Baumann (correct me if I'm wrong Dave) once wrote that they couldn't find a reasonable market slot for a 384-bit Tonga. I took that to mean that the performance gained in sales driving benchmarks didn't justify the added cost of a wider bus+components. So as far as I understood it, it was a decision made from the how the market actually appeared at the time of retail availability.

 

So, apparently the full desktop configuration of AMDs RX 470 is not only headed for, but built into Notebooks like part of the Alienware line-up:

I wonder why the GTX 1060 isn't an option. Perhaps the RX 470 sells for a lot less within a smaller performance differential?

 

For what i have understand, thoses new Alienware have both the AMD and Nvidia option, with 1060-1070 on the "nvidia one ."

Its funny, because most article who have been online today, only cite the Nvidia option.

You're right, forget that.
I saw Dell's own press release and they have the 1060 in a different line so that's why it passed through me.
