GDDR5X vs HBM2?

GDDR5X vs HBM2?

There are no consumer cards on the market with HBM2 right now and there probably won't be until 2017 at the earliest.

Any comparisons are pretty worthless right now.

>When you're a 30+ aged man and you play video games as a hobby and people dislike it, whats your argument?

Ok then lets say HBM vs G5X both being available

Anyone know what those HBM stacks actually cost? GDDR chips are only a few dollars themselves. I have never been able to find out if HBM is just 2x the price or something crazy like $50 per stack.

HBM2 completely and utterly BTFO GDDR5X, cost and assembly issues are the only reasons not to use it.

GDDR5X exists a cheap intermediary, providing more bandwidth than GDDR5 without increasing power consumption further. Uses standard GDDR5 PHY.

HBM has a tremendous advantage in bandwidth/watt. Its PHY is absurdly small, and contributes far less leakage to an ASIC.
With HBM1 the memory modules themselves provided 128GB/s for slightly less than 4w.
The only downside to it is that your memory capacity is ultimately limited by the density of the stacks you use. If you only have 4GB stacks, then an ASIC will be limited to 4x4GB unless you used two of them ganged together which is a patchwork solution no one will ever implement.

HBM2 effectively doubles the data rate over HBM1, and does so at slightly reduced power. A single HBM2 stack can provide 256GB/s for less than 4w.

I've never found pricing listed online, likely because its not available to anyone except AMD and Nvidia right now.
The price per stack is probably prohibitively high, but not as high as $50 per stack.

Others are using them in embedded stuff. Never seen prices anywhere though.

It's like comparing a sports car to a budget sedan, no one is going to say, the low cost sedan outperforms the sports car because it costs less.

But the sports car barely costs more to make, it's just marketed as a premium.

Like iPhone 6s vs redmi note 3 pro.

Hardware cost is close, but one is a premium product and one is a Chinese phone.

>But the sports car barely costs more to make
That's categorically not true. Are you seriously that fucking stupid?

Are you?

>sports car barely costs more to make

>high quality materials
>limited quantity
>mostly manual labor
fucking retard

forgot R&D cost compared to the quantity of units produced
retard

GM puts the same shit in a Cruze as they do in the Corvette mate.

>It's like comparing a sports car to a budget sedan
No, not at all. The only reason HBM isn't used in everything is because it's new.

It's a superior design, and will eventually render GDDR5/5X obsolete.

Honestly, I hope Intel and AMD get into the business of memory integration on the CPU die. Eliminating the need for RAM slots would help make boards more capable and cheaper to make.

>1.4L 4cylinder. 153 hp
>6.2L 8cylunder 455 to 455 hp

Just some quick googling and ignoring different packages its safe to say you are
Baiting
Or
You're are literally retarded

>But the sports car barely costs more to make
It does cost a lot more to make.

They have full carbon or aluminum/titanium chassis, which costs as much as a middle-class sedan on it's own.
Then they have aluminum alloy laser cut engine blocks, that are supposed to withstand crazy pressure, because of the turbo/supercharger
Then there is a double clutch or an electrohydraulic manual transmission with carbon clutch and tungsten gears.
etc etc etc

>whats your argument?
Why would you need one? Is their waste of time more logical than yours?

Nah m8, they put their truck engines in their sports cars, upgrade a few parts, and tune them to the tits.

And the trucks with those engines cost almost as much as the sports car.

Why don't we have 128 bit operating systems? Not shitposting, I genuinely want to know.

because you're a fucking retard who must go back to

If by same shit you mean, switchgear and seatbelts, sure.
>truck engine
Nice meme.

Stop talking about this, you people are clueless.

ok, kid.

We don't really need to handle that many 128 bit numbers.
