Next AMD Flagship Single-GPU Card to Feature HBM

AMD's next flagship single-GPU graphics card, codenamed "Fiji," could feature High-Bandwidth Memory (HBM). The technology allows for increased memory bandwidth using stacked DRAM, while reducing the pin-count of the GPU, needed to achieve that bandwidth, possibly reducing die-size and TDP. Despite this, "Fiji" could feature TDP hovering the 300W mark, because AMD will cram in all the pixel-crunching muscle it can, at the expense of efficiency from other components, such as memory. AMD is expected to launch new GPUs in 2015, despite slow progress from foundry partner TSMC to introduce newer silicon fabs; as the company's lineup is fast losing competitiveness to NVIDIA's GeForce "Maxwell" family.

Incorrect. Carrizo supports DDR3 and is 28nm



You are more than likely thinking of Zen, the generation after Carrizowhich is mooted to be specced for DDR4 support and made on Globalfoundries (Samsung) 14nm-XM process.

I know... that's why I used the faces with beers haha

how awesome would a fm3 with drr4 be if the cpu side went up to 8 threads and had some ipc to turn heads.

I need to understand this 4096bit BUS of 380X/390X...

HBM's I/O is 1024 per stack. Currently 4 stacks is the maximum, hence 4096bit. Not an actual 4096bit bus, it will be connected by a regular 256bit bus, but it would act as if it was 4096bit. Think of it like GDDR5 vs GDDR3, same speed and interface, just that GDDR5 can send more data per clock.

Not with 4GB :laugh: HBM 2.0 can't come fast enough... and, for a change, AMD should keep HBM for themselves at least for a while instead of making it a standard like GDDR3/4/5. All this "doing the work for everyone" mindset is killing them.

I still think 4k is better suited for like editing and artists. have you seen the 5k mac with a 295m?

How can they keep another companies product for themselves? HBM is primarily a SK Hynix creation which partnered with AMD on devising the spec. The JEDEC specification was ratified over a year ago (JESD235).

Nvidia might feel the same way regarding ShadowPlay, G-Sync, the frame pacing algorithm, the entire GPGPU co-processor industry, and discrete mobile graphics card modules amongst a few other technologies, while Intel developed tech that AMD presently uses would probably fill this entire page. It's very far from a one sided arrangement.

opps, wasn't aware that it was a standard already

I believe its timing exclusivity which results in first to market.

My guess is 380s & 390s will be HBM with lower tiers still using DDR5. The talked about late Q1 to Q2 300 series release will put HBM 2 production in line with a 400 series release Q3 2016/Q1 2017

Yeah, that one got rushed through. Less to do with graphics cards than getting established ahead of the competitionfor adoption I think.Wide I/O 2 isn't that far off either, so Hynix needed to get the product front and centre.

Looks like the Fixer is back.


Maybe he is going to fix cards that aren't using there full 4GB perhaps

Well I doubt it's to fix AMD's financial situation. Maybe they should trade in Fixer 3 for Miracle Worker 1.

If it's supposedly graphics related thenit ain't happening anytime soon. Of course, Gibbo stipulates "new product" so I guess there's a chance that the HD 7970 gets a fourth rebranding as a 300 series card!

The Fixer videos have never announced anything. They just seem to be a cheesy stab at humor.

Didn't he pay you a visit ?

I much preferredRoy Taylor's cheesy stab at humour. Pity that AMD didn't appreciate his humour since they demoted him soon after.
After AMD's last publicity extravaganza, I wonder if the lastest video is preparation for the announcement of the R9 285's launch in Somalia

So, just a placeholder for the dust-laden press release that proclaims three consecutive profitable financial quarters!

If he did, he didn't get past the front door, as with any other door-knocking religious zealots or panhandlers who happen by.

Don't underestimate AMD's marketing. This is a company that marketed a supposedly high-end platform with a cheesy comic bookblatantly announcing AMD's insecurity regarding Intel.
