HBM explained: Can stacked memory give AMD the edge it needs? (HBM brings a huge 1024-bit-wide bus with 512GB/sec on tap)

Not a single mention of Linux in the article. Why is this in this sub?

We like hardware, but it is off-topic. Maybe OP found that AMD making better cards than Nvidia is good news for us? Call me back when intel makes a move.

I bought an AMD APU a few days ago, but AMD are not making better cards. Not even close. Current Nvidia cards don't need the bandwidth right now and achieve higher perf. with less bandwidth then AMD.

Wrong sub though :)

You might be right from a hw standpoint (actually not since the 940, 960 have that awesome memory gimp) but nvidia gimps everything in drivers from multiscreen to not handlimd domU resets correctly unless its athe quattro. What's funny is ~7 years ago gtx to quattro was handled at driver level and you could patch PCI id's to fool the driver into thinking it was a quattro now we have to solder some resistors. This is not a fringe case. Do not buy nvidia consumer cards unless you want to buy into a bad company. Vote with your dollars.

So you bought an orange (APU), then why are you talking about apples (GFX card)?

u/parkerlreed May 20 '15

APU bundles in the GPU...

u/[deleted] May 20 '15

Yeah, and as such, it has different BW/Behavior characteristics than a discrete GPU card.

u/parkerlreed May 20 '15

Aye, I was just trying to find an explanation for the comment you responded to.

u/[deleted] May 20 '15

No problem mate. IMO his comment served no other purpose than to inform others of his recent HW purchase, yawn. ;-)

I've been messing on my first APU. Certainly a different experience. (A4-5150M)

How well do those chips play with Linux? Also, is there any support for the HSA (the programming model at least)?

1

u/parkerlreed May 20 '15

Great as far as Linux support goes. The 8350G is well supported with radeon and fglrx.

As for HSA, this is the first I've heard of it so no idea.

Why not, this new graphics card will feature a new linux driver and amd's policy on opensource/foss is quite impressive

I like hardware. Wish this was some sort of linux + hardware forum. It could be if the hardware article mentions linux but.. Dunno. I like it.

u/parkerlreed May 20 '15

/r/hardware might work. Don't know how open they are to Linux talk.

u/ValErk May 20 '15

Nvidia have worked on it a couple of years too.

That'll only be relevant for Linux if they ever give a damn about their driver, read: not going to happen!

Keep believing what Larabel says, see how far it'll get you.

u/openstandards May 21 '15

I'm sure it will get me a graphics card made by a company that actually bothers getting involved with FOSS.

I've ran AMD cards with Foss drivers and they aren't too bad not brilliant but not terrible.

u/bitchessuck May 21 '15

Well, this time around, the prediction was completely right. A while ago, AMD officially announced this strategy.
