like badly placed transistors that are too close to each other causing high power leaks at high clock speeds.
Planar to Finfet isn't a straightforward copy paste, they do have to revise the architecture to function properly in Finfet.
and to begin with, Maxwell is a good overclocker, so its just normal if they managed to pull a bit more potential on the architecture while they're at it.
be that as it may, you sit here and complain about the name if that's what you do for entertainment, I'll spend that time playing on 1070 SLI

wow, how affected are you from me saying "pascal doesn't deserve it's name", just to quote me to say "i've got 1070 SLI, you jelly?", i'm quite baffled.

lol what a childish amd fanboy a person must be to express their disappointment from the name of the architecture of a gpu they'll never buy because of brand bias
with a problem like yours you should be on Jerry Springer show not on ocn.

its one thing to forgo certain features, but to forgo a crucial part of an API which would be more often used in the future is akin to putting one foot into a grave.
to make matters worse, Pascal's IPC had hardly increased over Maxwell, GTX1070 = 1920SP @ 1683Mhz / GTX980Ti = 2816SP @ 1076~1202Mhz.
( 1920 / 2816 = 0.682 ) * ( 1683 / 1076~1202 = 1.564~1.400 ) = 1.07~0.955, or roughly within ~101% IPC of GTX980Ti.

(1920*1873)/(2816*1202) = 1.06 = 6% IPC increase

That is correct if GTX 980Ti is as fast as GTX 1070. But it isnt.
GTX 1070 is 14% faster.

So in reality you are looking at a 15-20% IPC over Maxwell

aren't you an Nvidia fanboy, as you're obviously affected by whatever i said.

i heard Nvidia was undermining their drivers for old gen. biggrin.gif


though on a serious note, good point, Pascal did probably get a bit of IPC increase.
but that 980Ti clock speed is questionable as Nvidia's boost clock is a PITA to track, either its 1076Mhz boost clock, or 1202Mhz boost clock.
((2816 * 1202) / (1920 * 1873)) / 0.88 = 1.070
((2816 * 1076) / (1920 * 1873)) / 0.88 = 0.957

Doing an EVGA step up to one of these since I only just bought a new card, can't wait! I have a feeling it'll take awhile before they start shipping them out.

[SNIP]

i get the sarcasm wink.gif

but i'd like to see more when both cards have the same driver afaik, no reviews have.

i'm seeing something...
GTX980Ti 368.22 -> 368.39 drivers have some games that had gotten i tiny bit slower! its a conspiracy! biggrin.gif


that one is using 368.39 on both 980Ti and 1070, thats a good start.
though i'm only seeing 3%~9% faster.

I'd say that is pretty darn good considering 970 was slower than 780Ti (9% according to techpowerup) and 1070 is faster than 980Ti (13% according to techpowerup), referring to reference in both cases tongue.gif




maxwell->pascal is significantly better than kepler -> maxwell if we're comparing new gen x70 vs old gen x80Ti . evidence right in front of you.

72% improvement in performance per watt compared to 970





but still disappointing for people who want a "mircale" rolleyes.gif probably expecting a card that runs 6 months on a 3V battery without having to plug it into PSU

That's because you're not comparing apples to apples in each case.

780 Ti was a full GK110, whereas 980 Ti is a cut down GM200. If comparing 970 vs 780 Ti, you should compare 1070 with Titan X. But this isn't much an issue.

In terms of perf/watt, you realize Kepler to Maxwell stayed on the same node right? As a result of a 1.5x shrink (28nm to 16nm FF), you should expect a huge increase in perf/watt just because of the process improvement alone. To wit:



670 had almost 2.1x better perf/watt compared to 550 Ti, which had comparable efficiency to the 560.

Warning: Spoiler! (Click to show)
perfwatt.gif

(670 = cut down GK104, and 560 = cut down GF114, which is why I'm comparing them)

Since Fermi to Kepler also involved a major arch update, it's hard to say specifically how much the arch change and process improvement each contributed to perf/watt. But if the perf/watt improvement going from 670 to 970 is any indication, most of the efficiency still comes from the process shrink. And incidentally since Pascal and Maxwell are so similar architecturally, it's also fair to say that most of the perf/watt improvement came from the process shrink.
