Samsung Starts Producing Industry's First 16-Gigabit GDDR6 Memory

[Hugh_Mungus]

Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today announced that it has started mass production of the industry's first 16-gigabit (Gb) Graphics Double Data Rate 6 (GDDR6) memory for use in advanced graphics processing for gaming devices and graphics cards as well as automotive, network and artificial intelligence systems. 

, the new GDDR6 operates at 1.35V to lower energy consumption approximately 35 percent over the widely used GDDR5 at 1.55V. The 10nm-class 16 Gb GDDR6 also brings about a 30 percent manufacturing productivity gain compared to the 20 nm 8Gb GDDR5.

I hate the calculations in that image, mainly because calling gigabits gigabytes is really throwing me off.

[Probably Alex]

Neat.

When do I get it in a graphics card?

Anyone know what the adoption time is for some new tech like this?

yeah it was a typo on the behalf of the commentor but I checked his math and its right

[Crunchy Dragon]

I'd be more excited if the DRAM shortage was fixed

But is it accurate?

And i dont understand the las tline 19.2/38.4 ... isnt a huge loss but hbm2 is finished? 

If G6 can match or outperform HBM2 at lower cost and higher production rate then i hope we can burry HBM2 and AMD can pull their head out of their assess, they lost a ton of marketshare because of HBM adventures that didnt pay out.

But now that GDDR6 is FASTER and CHEAPER than HBM2. Also They said that they can produce it 30% faster. Hopefully this means that GDDR6 won't be the supply bottleneck in the next generation of graphics cards and hopefully prices will come down.

I think your post is missing some pretty important information...like how at a 384bit bus, GDDR6 does 864 GB/s. That absolutely crushes HBM2.

HBM3 is what will be most interesting.

yea, but... Holy shit!  So this is what it must have felt like to have been a BETAMAX cheerleader.

Ya know you're right; ya know it's better.  In a just world you should win, but ya know yer gonna lose.

 

Well, too bad.  HBM can't get its act together.  It's not iterating in worthwhile manner fast enough, and it's not doing a good enough job at bringing down its cost to manufacture.  So, buh-bye I guess.

In before gddr6 has better mining capabilities

Not happening. They won't handicap a product to stop sales.

But on a 4096 bit bus, hbm2 can do 1TB/s, which crushes gddr6. The only way g6 can match it is with a 512 bit bus, AND it needs to run at high speed  which has never been done.

Unfortunately, manufacturers don't care who buys their products. They make money whether they are miners or gamers; significantly more if you are a miner since you would be inclined to buy more that one. That being said, the best thing you can do is hope that GDDR5 would still be the most efficient choice for mining.

Do they use a 4096 bit bus? Honestly don't know, never bothered looking at HBM cards after seeing the lack of performance.

Vega 64 and 56 use a 2048-bit Bus.

 

 

Keep in mind, HBM also operates at under 1000 MHz at stock (under 2000 MHz effective).

 

We don't know what memory bus width GPU manufactures will use, and how fast GDDR6 can operate at -- frequency wise.

HBM was only used at that bus side for HBM1, and every single version so far hasn't been capable of the intended clock speed (bloody Hynix), thus slowing it even further.

Well.... it makes the card smaller....

Hmmm. I see. Does memory speed have anything to do with what frequency they'll operate at?
Looking at this chart (yeah yeah, I know, horrible source) https://wccftech.com/samsung-gddr6-16gb-18gbps-mass-production-official/ it looks like there will be quite an increase from the current 10,000 to 18,000. Though, likely only a 2,000 increase on most consumer cards I'd imagine.

Can GDDRx not run at a higher bus than 384?

Thats because Samsung delayed their hbm2. By the time gddr6 is out, supply and speed will likely be sorted out

Gddr can run any bus width in theory. Largest we've seen in practice is 512 bits. And by then the memory is clocked slowly to reduce the already exploding power budget of the memory, not to mention IMC size and power. 

[mr moose]

All technology is limited by its weakest trait.  It doesn't matter which product type is technically better, if it can't meet demand or costs make it prohibitive, then it is is the inferior tech for the end use.     In this case HBM might get there eventually, but maybe not. Either way the tech that wins out will be the tech that puts a GPU in my PC (which means it costs what I can afford).

I see. Maybe the reduced power consumption will let them run it at something between 512 and 1024 bit. Though I only see AMD attempting that, Nvidia has been pretty focused on low power consumption the last few years.

I don't think so . Power is one concern . But there's the even bigger concern of having to route 1024 traces on a PCB for memory.

I don't think that's that big of an issue considering they've done 4x that before on consumer cards.
