AMD's obsession with HBM can only be explain in 1 reason. They wanted to drive HBM cost down so they can use it on APU.

So with HBM enabled APU, it can allow AMD to hurt $100-$200 discrete market sales. May be even $200-$300 ones. Pushing Nvidia to only sell high end discrete GPU.

The 4870 was an epic card, not only could it compete with the 280's at a much lower price it was also the first TFlop card. I loved mine so much I got one for everyone in the house. If it wasn't for its extreme high power use I would still consider it a great entry card.

They need it for power saving reasons too

Probably for Bandwidth reasons, lower latency,smaller footprint,better thermla disipation,more density per area but probably for APUs the best solution is something can get a good amount of vram with the least power, then for power saving,heat dissipation and Bandwidth/latency might be a good reason for banwidth limited processors, and HBCC would be interesting fi it could be applied to IGPs

I'd much rather see an AMD GPU monopoly than an Nvidia one, solely because we've seen how Nvidia behaves when they just have a lead.

I've heard countless times Windows is a walled garden of an OS, has questionable tactics of forcing people to Windows 10 (especially if you care about dx12, or new hardware with your older OS) and yet we still use it.

Seeing a monopoly at all is a bad thing in any market; you should know that even if it conflicts emotionally with our favorite corporations.

But hey, this is ocn at the end of the day.

Is peak bandwidth all that matters with vram? I imagine Fury X has quicker ram than Titan Xp because its on-die.

@ KyadCK
Nitpicking won't help. Non of the issues you mentioned are as bad as lazy rebranding. And to make matters worse, AMD has been the Rebrand king since a few years. Some Radeon models even got rebranded several times. Look at the whole series level, getting Rebranded way too much. See HD6000 series, then R7/9-200 -> 300 and now RX400 -> RX500 series. Nvidia had their rebrand too, but outside of mobile chips or low-end OEM models, it weren't nearly as much as AMD did in the recent years. There is no excuse for denying the customers new hardware and try to fool them too. Nvidia at least hat the dignity to lower the tier of the cards going from 80 to 70 and 70 to 60 a.s.o!

AMD is not even thinking about his and just patches everything ab by the first number. If you bought a R9-290/290X in 2014, you still haven't gotten the chance for anything faster, low availability and high prices from Fiji aside. Try to knock at that door and make your favorite company a little more fire under their lazy butts. They either bring nothing, the old crap, or it takes forever - like Vega. rolleyes.gif

If they were more open to other memory technologies, the whole waiting game could be shortened, if not elminated.


Very unlikely. A jump from 11 -> 12 Gbps is not enough for a new series. If Nvidia brings new cards, they will bring new tech too. The 1000-series got their mini-update and as good as every model as possible.

Like I said, the lower to mid-end might get the GDDR5X treatment while the upper tiers move up to GDDR6. The highest Titan model might get a HBM2 configuration again, but I can't say if this is coming for us consmers too.
That depends on which tier of cards Nvidai brings first. If the 2080 and 2070 are first, some of them might still have GDDR5X onboard. If we are lucky there will be an updated card in the 1070 territory on tier lower as 2060 with GDDR5X too. Everything above will be equipped better. Nvidia is known for their contracts with the suppliers. if they want GDDR6, they get it in advance like Apple. They could even secure more HBM2 for their professional line than AMD could in the whole year.

Gddr6 is still way too early. Pascal almost miss its g5x adoption. I would say volta will be facing same issue.

I wouldnt count on G6 this year. If they release volta this year. It will be 12gbps g5x

Fury X only had ~330 GB/s of usable bandwidth (or slightly more with compression) despite having 512 GB/s in theory, so I wouldn't write the bottleneck off entirely. In that regard it wasn't a large upgrade even over a 290X. Vega should be able to nearly double that with better memory controllers and better compression.

Which completely makes sense, since most of the cost of those cards comes from the board and memory. Transferring that to the mobo and APU should bring cost way down. I don't think they'll compete with $200+ cards before die stacking is a thing (and I'm not talking about memory).

Sustained bandwidth is, really. As long as the latency isn't massively higher it typically doesn't really affect GPU performance.

HBM has no royalties
That's why Nvidia is using them too.

HBM3 (2019) will have double the bandwidth of HBM2.

Thank you smile.gif

I was about to post but realized I didn't need too.

Big Tree deserves upvotes!
