Pascal with HBM2 not available until Aug 2016 - GDDR5X versions releasing April
Glad I didn't fall for the waiting meme
I'm sitting on an Ivy Bridge iGPU atm, so I might be tempted by an early AMD/Nvidia offering. How much will HBM2 matter over GDDR, anyway? There doesn't seem to be anything special about the Fury X.
HBM has faster transfer rates. 4 HBM modules deliver 512GB/s and the fastest GDDR5 vRAM delivers around ~350GB/s.
HBM2 is suppose to go up to 1TB/s but will probably only be in top end graphics cards.
Interesting to note is GDDR5X is actually slower (448gb/s max) than even ancient HBM. Pascal is gonna flop HARD because of this. By the time Nvidia puts HBM2 cards on shelves, Polaris would have probably already sold out. Nvidia will be left to eat the crumbs left behind by AMD.
Shit don't look too good.
lolnope, gddr5x is actually slower than hbm
nvidia fucked up big time.
>Nvidia will be left to eat the crumbs left behind by AMD.
>implying Nvidia won't create new cake that will redefine future cakes (that AMD will be eating crumbs from)
yikes, are you really this delusional?
>all this confusion from nvidia
Is it all downhill? Also, what will the new Titan be called?
They already used:
- Titan X
- Titan Z
- Titan Black
not quite btfo, but fury x > 980ti at 4k
>The gtx 780ti was the last card you should've bought
Any Ti card is high-value. In fact, they're the only smart buys if you're not a poorfag.
With the continued use of GDDR5 for the first batch of Pascals, it looks like 980 Ti will continue the trend.
>there is no more Titan.
I'm sorry, who crowned you king of nvidia?
That's a 980.
If you own a 970/980 and overclock you will notice how memory bandwidth limited those cards are >>52626235
Fucking Nvidia and their loss less color compression shit allows them to jew it up even more on the memory.
The GDDR5X versions of pascal cards will be on 28nm? Holy shit, nvidia has gone insane.
Isn't Pascal supposed to be 14nm? Just because it's using GDDR5X doesn't mean anything about it being 28nm. Nvidia would be really stupid to release a 28nm product a couple months now before they release something 14nm and tarnish Pascal as a marketing term.
Isn't that figure with just a 256bit bus though?
384bit will put it over 650GB/s I don't see the reason why they won't use 384bit or even 512bit unless it's physically impossible for some reason.
you are both idiots.
the three biggests bottlenecks in modern GPUs/games are:
> memory bandwidth
> shader ALU capacity
> fixed function unit (ROP/TMU/tesselator) capacity
For the last few generations, AMD has gone heavy on memory bw and ALUs and skimped on the fixed function units.
For this reason, Nvidia made TWIMTBP/HairWorks/GameWorks middleware that basically floods scenes with tessellated triangles for no reason other than Radeons will choke on those first.
AMD's push is for ALU-heavy stuff, like post-processing effects and async shaders, but they don't seem to bribe as many devs.
>I see no reason for Pascal or Polaris to be anything other than a full 1xnm top-to-bottom line-up.
new lithography nodes are drastically more expensive per wafer and often significantly more expensive per transistor until yields rise and stabilize.
cheapo Polaris/Pascal cards built on 28nm with DP1.3/HDMI2.0/h.265 upgrades and minor tweaks to the rendering pipeline are perfectly reasonable if not exactly guaranteed to happen.
You idiots fucking wish
Go look up the 4k version too, you'll be in for a surprise.
I wouldn't recommend it though, because the Fury X is too weak for 4k and the 4gb vram chokes on some games.
Do people seriously believe that there is gonna be FUCKALL of a performance difference between both memories when they're all probably gonna have like 6gb+ from x70 onwards at least?
I swear VRAM is the new RAM buzzword for tech illiterates. More than ever I'm actually seeing a LOT of people talking about GPUs as if their power was measured by their fucking memory amount. It gets even fucking worse when I witness retards thinking that VRAM is all that matters for 4k.
Reminds me of all those bitrate starved GPUs that have WAY more memory they can handle, such as 760/770 and their 4gbs models or the r9 390 with its retarded 8gb amount of memory.
Just to clarify before some sperg loses his shit. I'm actually talking about real world performance as in FPS gains on games.
Not this MUH SYNTHETIC USELESS BENCHMARKS placebo trash.
gddr5x is, at most, twice as fast as gddr5. But that's a "down the line" speed, not what it can currently achieve. Right now it is 1.5x faster or so.
HBM is 4x faster than gddr5, HBM2 is 8x faster. And with a quarter of power usage.
>GTX 770 plays everything I want.
>Most of the games that benefit from 120fps are piss-easy to run.
>By the time I can afford a 4k/superwide monitor and a VR headset, Pascal will already be out.
>probably the GTXdesu80Ti flagship card, too.
I'm totally invested in the waiting meme, OP. You should invest too.
HBM2 at present will scale up to 1TB/s. Future shrinks could double data rate again simply by increase frequency inside of the given power envelope.
GDDR5X is a great low cost stop-gap measure for entry level and mid range GPUs. It is not a competing technology.
>2gb low end cards are bad
Its not like 4 bad ddr3 4gigabit chips are much more expensive than 4 bad 2gigabit ones.
Also having more memory is always a good thing, i've seen some games refuse to launch if your gpu doesnt have a minimum ammount of memory. 512mb/1gb feels appropriate for those gpus but its not like the price difference matters that much compared to marketing a 512mb card.
Plus if you wanted to see how nice games are with graphics all out you technically could even on those low end models. At 3fps but you could. You're right tho on 4gb versions of those cards.
In the end i am more amazed that the 970 and 980 only hold 4gb of memory while the laptop counterparts 970m and 980m have both 4gb and 8gb versions. Immagine the salt if the 970m had an 8gb version and the 3.5+0.5 meme became 7+1. I bet nobody would care anymore
