What I mean by finicky frequency and voltage table is MSI Afterburner allows to control the voltage as per frequency curve on Pascal cards but it seems to have a mind of its own, everytime I undervolt too much it refuses to reach that frequency and stuck on lower frequency. A lot of new cards too seems to do this, Vega included. If I undervolt, example 900mV on Vega the frequency will hover around 1350MHz on complex games and 14xxMHz on simpler games disregard whatever I set. Its ok-ish since the card clever enough to know its own limit and keeps stable but very hard to do clock-to-clock comparison.

I love tweaking, almost everything I have is non-stock and modded in some way or another whether in software or hardware so Im a big exception from regular people.

I traded 980Ti with Vega56 for RM300 so win-win for me laugh.gif

Oh, yeah that annoy me a little too.

980Ti+300 for a Vega 56 is a great deal. I thought you had 1080 Ti at one point? What happen to the card?

QUOTE(shirohamada @ Dec 10 2018, 04:18 PM)
you definitely got a great deal.
980ti is faster than 1060 6gb but slower than 1070. doh.gif

if i want to buy a 980ti i would only pay rm500 max. even that i don't want it.

Depend how far you can overclock both, usually 1070 just very slightly ahead.

Sold it off, reckon I dont need 1080Ti for 1080p. Bought 980Ti and some money for other expenses. I dont like to use a card that I cant tweak tongue.gif Its damn powerful though.

vega likes water no need to undervolt just let it loose 1.6ghz and above is no issues thumbup.gif

vega, polaris and the 14nm low power plus does not like clock speed.
undervolt at 1.4GHz and you will get peak efficiency.

eh, GTX 980 Ti stock is below GTX 1070, OC models are higher than GTX 1070.

It's around GTX 1070 Ti level actually.

er, that chart is exactly what I'm telling you.

You said "980ti is faster than 1060 6gb but slower than 1070."

I'm telling you that a factory overclocked GTX 980 Ti is faster than the GTX 1070 (in reference to stock model).

Based on the chart a heavily OCed 980 Ti comes to around 90% - 95% mark which is very close to the 100% of the GTX 1070 Ti.

You can read my findings here https://www.goldfries.com/hardware-reviews/...cs-card-review/

tldr; - Stock 980 Ti is behind stock 1070 but factory OC model is actually faster than 1070.

Any feedback/comment about the new Adrenalin driver guys? hmm.gif
Auto OC (auto undervolt and shits), memory timing, more DPM state on Vega GPU.

Bruh, that 980 Ti already thermal throttling on day 1. I can only imagine it get worse 3 years later.

Let me do the math for you.
From your graph the 1070 Ti is 26% faster than ref 980 Ti.

From this sub 1500mhz 980 Ti OC chart,

The 980 Ti OC is 33% faster than ref 980 Ti. 33 > 26 so 980 Ti > "non-oc" 1070 Ti yay top kek.
But of course driver optimization is a thing, Maxwell get slower optimization nowadays compare to Pascal.

i can't believe people are defending a 28nm housefire overcocked 980ti. in dec 2018.
at least with vega you have the option to undervolt and save 30% power.
it has ridiculously voltage overhead.

as for rm500 980ti, sounds about right. 1070 is already rm950.
if you price it rm700, might as well go 1070, which you can oc yourself get a 16nm chip and soon to be gimped drivers.
980ti is just junk and not worth buying today.

huehuehue
