Supposedly leaked 1080ti specs show GDDR5 (non x) 

 

So apparently there's some sort of leak showing the Specs for the 1080ti which as suspected is a slightly cut down version of the Titan XP but a surprising and doubtful claim: it sports normal GDDR5 not the newer GDDR5X found on the 1080 and the Titan XP:

Nvidia's GTX 1080 Ti's specifications have been leaked, showcasing a GPU with 12GB of GDDR5 memory and 768 more CUDA cores than the GTX 1080.

The Nvidia GTX 1080 Ti is said to be made using Nvidia's GP102 GPU core design, which means that it is based on the same GPU as the GTX Titan Pascal.  Nvidia has made two significant downgrades with the GTX 1080 Ti from the Titan Pascal, changing the GDDR5X memory to slower GDDR5 and taking away 4 SM units from the GPU. 

This will give the GTX 1080Ti a total of 3328 CUDA cores, which is a 768 more CUDA cores than the GTX 1080 and 256 fewer GPU cores than the GTX Titan Pascal.

In this case the "source" appears to be just a forum post on their forums so take it with a few truckloads of salt specially because well, why go with different memory than the 2 nearest cards? Overall very weird even though the Memory Bandwidth seems to be what you'd expect I am extremely skeptical myself.

Interesting, so again rebranded titan x

I call BS, releasing this card would undermine Titan XP's spot on the market and the 1080 already has no competition and a Ti version would also cut its sales short.

 

EDIT: MAYYYYYBE around Vega launch, but then again, Volta won't be far after Vega launches, so I don't really see the point imho.

[Rune]

Don't believe anything that begins with "So apparently" or "supposedly"

[captain cactus]

Pffft, nVidia would shoot themselves in the foot if G5X wasn't available on a model marketed higher than the 1080. I call BS.

They've done so in the past. It really depends on the timing and one would assume at least after Vega.

 

But yeah I can't really dispute your bullshit call though.

[rattacko123]

Well they want people to have a reason to buy the titan xp over the 1080 ti, so it makes sense

384-bit GDDR5 is faster than 256-bit GDDR5X anyway, so it doesn't really matter imo

[Bouzoo]

Not only a non X model but also lower clocks than 1070 as well. Cut down Titan all right.

Not to mention the GDDR5 thing... Unreasonable imho, considering that a 1080 has GDDR5X already... Yeah, after Vega, but how far are we after Vega launches to Volta? Not too far imho.

That's the weirdest part indeed: The purpose would be to bin some cards as 1080ti and use the rejects for 1070 however that's close to two thirds of the fucking CUDA cores disabled. I'd find that hard to believe that they wouldn't have an in between tier if that was the case since most 1070s then would be shipping with perfectly fine CUDA cores disabled for the sake of consistency of specs.

Wait what? That would be dumb o-o

[Nano0806]

Possible dumb question warning....

Is the difference from GDDR5 to GDDR5X thaat big, and I mean not numbers, real world gaming performance difference to be worth all the fuss?

at a higher res it really does help, think about the people who want to SLI these cards for 4k

If the chart is anything to go by not really: GDDR5 seems to be faster than GDDR5X if it's fed with a wider bus.

There's something called memory compression though, my 290X has around the same memory bandwidth as a 1080, but I assure you that a 1080 would be faster in memory-intensive applications due to GDDR5X, despite a 290X wrecking most of other Nvidia cards in that regard

I call BS.

So it means that we might be sitting on the doors of yet another Nvidia vram controversy, this time crippled speeds not crippled amounts.

 

Oh wait, crippled vram speeds? We had 0.5 of those last gen

yes @TrigrH indeed, higher res can actually benefit but...

... @Misanthrope has a very good point, wider bus  >  just an X after GDDR5

but the bus cant and wont be wider for the 1080ti so....

It already is wider from the Titan XP vs the 1080: 384bit vs 256bit. So why "cant" it be wider?

really......look in the table posted by OP 384 bit > 256bit. If info is legit...it's wider

then I'm calling BS on the rumour as the 1080 and the 1070 both have the same BUS width.

Previous x80 cards were actually cut down/modified versions of the Titan cards. That part doesn't seems as strange to me. The fact that they'd use GDDR5 and not GDDR5X is a little suspect but not the bus imo.

[Clanscorpia]

This some bulllllllllll

but....the 1080 and 1070 DO HAVE the same bus width. Check nVidia official specs
