Pascal Titan-X Launch

[Besty]

Greebo: I think you are off the mark, max average clock on air for the 1080 seems to be 2.1ghz regardless of volts. which magically is the max clock the original deministration was done at.

the guys on warm water seem to be hitting the Same ceiling, they might get getting higher clocks than 2.1 but pascal is not giving out more performance. people might be getting 2.2ghz but the performance tends to be worse than the cherry FE cards doing 2.1.

as for the average clocks of the new Titan going faster than 2.1 then I doubt that also.

you might get some dudes with chillers and the odd screenshot on the net but generally speaking these chips just ain't happy over 2.1ghz.

I await to see what the kingpin editions of the 1080 do, my guess is is that they are going to need exotic cooling to break 2.2ghz for gaming clocks.

Not really surprising as most other products tend to aim for about 1.86GHz max on TSMC 16nm FF+ never mind a GPU size product.

i suspect wont do any better than the 1080 and I never claimed it would?????

People with the 1.25v Asus bios with better tdp are hitting 2.1 to 2.2 on air and 2.3 to 2.4 on water according to other forums.

Of course that means nothing if that extra speed is giving you worse performance than your old bios at less than 2.1/

Is Gregster avoiding this thread ?

I think so, probably turned his pc off, sat in the corner with his fingers in his ears saying to himself " I don't need it I don't need it"

Nah I bet he reappears with a pic in the owners thread along with a YouTube review very soon

No its purely because HBM is limited to 4GB. Would anybody have bought the Titan XP if it only had 4gb memory, half of a 1080?

No way would Nvidia release a top end gaming card with 4Gb ram and make the same mistake AMD did.

Thats why they waited for HBM2.

Nvidias next high end gaming card will have 16Gb HBM2 ram and mid/high range will have 8Gb.

The 980 was a top end 4GB card for a good 6 months .
The reason they didn't use it is because they didn't particularly need it (as opposed to having true choice in the matter) even if they could have used it so early (really unlikely). They have good foresight and planning, true, but that Nv HBM narrative is off.

The Pascal Titan has put a spanner in the works for a 1080 Kingpin Edition as it has missed the boat performance wise.

I would not be surprised if EVGA skip the 1080 and do something with the GP102 for the Kingpin brand.

 

[RanxZy]

Why not ebay your TX and get a 1080 while you are waiting, looking on ebay the TX still go for almost as much as you could get a 1080 for, so that is 20% performance increase for almost nothing.

Did have a EVGA Hybrid 1080 on order when it was £680 but cancelled it. I've never actually bought a x80 card, always been the 670, 970 etc. Actually only got the Titan X recently for £430 on the mm as they were going cheap from those upgrading to the 1080. Will be all over the next card released on this GP102 core though, I'll get a Ultra HD tv to give it some work to do.

NVidia already have 16gb HBM2 compute cards based on the GP100 so it is not memory capacity stopping them.

 

[DmitryD]

If Nvidia were to release a version of this in say 6 months with 3840 CUDA cores and HBM2 memory, would the buyers of the current Titan X's be annoyed?

It won't happen because HBM2 only used for super expensive compute version with a lot of FP64s.

Volta is coming soon, now that MUST have Titan X for Victory with HBM2 - with 5k shaders to boot

 

[VincentHanna]

Is it correct that HBM2 would be 10x the speed of GDDR5x?

1TB/s instead of 10GB/s

 

[Rroff]

GDDR5X is more like approx half the speed of HBM2 as per the most common usage. In theory it could be scaled upto the same levels of bandwidth but more expensive and bigger thermal and power considerations than HBM2.

 

[Greebo]

Is it correct that HBM2 would be 10x the speed of GDDR5x?

1TB/s instead of 10GB/s

gddr5x is 64Gb/s max (in theory) and HBM2 is 256Gb/s so 4 times faster.

Of course a lot depends on how it it used etc.

The main benefit is the 56% less power used with HBM2 which means you can use double the gddr5x memory and still be at 250W or use the same amount of HBM2 memory and have a bigger, more power hungry gpu and stil come in at 250W.

Based on bus used then GDDRX5 maxes out at 448GB/s atm and HBM2 will be 1TB/s with 4 stacked chips on a 1024 bit bus so roughly double the throughput for half the power usuage.

Pascal was always slated to have HBM2 but it hasnt materialized ................yet.

Depending when Volta lands, there could be another Titan pascal with HBM2 (16Gb) and a 1080ti with HBM2 (9 Gb) to fill the gap.

Come on Greg, do it!! Who needs nuts anyway

 

[NirK]

Could be that Nvidia are done with Pascal now and will be focusing on Volta, I don't know though, just a guess based on what I have read. Or they might release a 1080ti at some point around Xmas.

Either Volta is coming early in Jan or they have got more pascal to release otherwise nvidia will be going almost a year without a new card.

In which case they could have kept Titan back until October and then a 1080ti in January time.

Or they needed to do something with GP102 chips that did not make the grade for the full fat compute cards.

Yeah but why release so quick? They still haven't shipped all the 1080s ordered so could have kept Titan till october

If NVidia can sell someone a Pascal Titan instead of a 1080 it only increases their profit.

Having said that the two cards are aimed at different markets.

 

[eddyr]

Yup, 2 ways they could go about the full die:


-Full die GP102 for Xmas - with 1080ti, +10% clocks. Priced $899-999?. But what to do with bad chips? Don't want to have to sell them at lower margins than the full die and and force cards down the range into even smaller margins earlier than is necessary. Otherwise Titan XPv2, priced ~$1249. But there are plenty who would spend between the 1080 and Titan price points.

so to maximise revenue go straight to,

- Further cut down GP102 as the Xmas 1080ti, only 26/30 SM enabled but clocked +15% higher than the Titan XP. Priced ~$799.
- Original Titan XP, with 28/30 SM made EOL in Q4 2016/Q1 2017, after 1080ti launch.
- Full die GP102 released as new Titan XPv2 in Q1 2017 (provides plenty of time to satisfy Quadro demand beforehand), 30/30 SM enabled, clocked +5/10% vs predecessor Titan XP. Priced ~$1249.

That's my thoughts and what I suggested early. A new Titan, call it black or z and a 1080ti slotted in between.

Both would sell.
