I understand that.

So, are you saying there some 'hidden' perf degradation due to exceeding TDP, i.e. it doesn't manifest as it has in the past, wherein one can see the card not holding max boost clock in the afterburner (generic term) Clock graphs?

Or are you saying these reviewers are so inept that they're not even confirming that the clocks are actually 'holding' at the OC'd level they've set via observing the graphs? Because they seem to all pretty much at least do THAT.

Because aside from those two explanations, seems to me like one is left w/the inevitable conclusion that the OC scaling on the card is just ... not very good.

1350-1450mhz is definitely the range that rx480 overclock to even with partner cards. And 1450mhz stable for 24/7 gaming is a golden card.

But Moey promised us cards with 1500 MHz set in the BIOS. Just wait until those come out - you'll see what the RX 480 can do then.

lol the truly fanatic people who don't use their brains much you could probably spot from a mile away

Then there are some people that just say it like it is and don't sugarcoat things, also glass half empty vs glass half full approach.

Actually from what I saw very few reviewers even noted that the reference card was dropping anywhere between 20-70mhz lower than the max stated boost, so lets not go down that road.

OC Scaling isn't the proper term, and as per AMD cards, the scaling is (almost) linear and rather high in comparison to Nvidia. Though I understand what you mean in terms of overall % the card can OC being disappointing. To that though, several users here have already shown 1400+ to be achievable with better air cooling and playing with PL and the bios. While it definitely takes a lot more effort, and I'm sure reviewers don't have enough time to spend with just one card, it's not like Maxwell/Pascal in the sense you hurr durr move a slider and bam that's the best you're gonna get without DICE/LN2 and lots of volts.

I'm sure AMD was afraid to increase stock TDP limits, as no matter what they're going to be axed by the general public and reviewers alike. Albeit we haven't seen a lot of samples for higher OC's, 1500, 1600, and 1700 have been achieved (yes I know, extreme mods and or water), but P10 seems like it can clock pretty well when given the right environment.

*Just for the sake of comparison from both p10 and 1080 high OC's on water vs base clocks...

1080 seemingly hits a wall around 2100-2200 max for air/water so far (haven't being paying a lot of attention I'll admit); (2200*100)/1607 = 36.9% increase in core clock speed

Don't have an exact wall for the RX480 but the best sample we've seen on water so far was 1530 if I recall; (1530*100)/1120 = 36.6%

Kinda scary how close it is between the two, (1070 will look much better having a lower base clock and similar ceiling to the 1080, ~42%). For the true sake of overclocking, and really getting down to the grit, p10 definitely isn't bad. From the few LN2 results we have, P10 is actually scaling higher in terms of a OC % over base clock than pascal.

Thanks for the name-calling, that is very professional. thumb.gif But I would agree that the 1500+MHz rumors appear to be unfounded at this point. What's more disappointing is the seeming lack of performance increase for the clocks that have been reached. Looks like the 1400MHz Nitro that PCWorld got would bring it pretty close to even to an OC'd 1060 but still slightly behind. Then again, it does only cost $220 and is a very solid looking card in build quality (far better than FE 1060 IMO, for a lot less money). The $260 8GB card should perform even better than the 4GB one tested but still will not outright beat the OC'd 1060 and pricing becomes problematic here as well.

I guess congrats on being right and for me being "a fool" that was wrong. I guess we can all go ahead and celebrate AMD going down in a dumpster fire and Nvidia charging $1000 for the next x80 card and $2000 for the next full chip Titan! What a great day it is to be a PC gamer and an Nvidia fanboy! specool.gif

Where I'm from we like to sugarcoat the poisoned pills so they're taken without immediate thought, only to burn you from the inside over a period of days after the fact. hypocritesmiley.png

 

I'm a glass-half-full sort but I've also never taken disappointment in a hardware company to heart. I can always buy from someone else, and failing that I can invest my life's savings and all future efforts into turning Matrox into a GPU juggernaut.

 

I mean, those wall-panels are pretty slick.

I am sure that if i get a 480 and a block i will scale it to 1500. But i know this is not the average and i expect an average around 1400 except some golden cards on air.

This card is like the previous gcn one so it needs a lot of cooling and a lot of volts to scale.

At 1500MHz you will be able to heat not only your house but your garage as well.
post #509 of 860
Doesn't matter if the 1060 is 1000x times better, if there's stuttering in games. Just saying ...

Ref 480@1520MHz



Same power consumption with 980 at same clock. Not really hot at all.
