Personally I would prefer a custom card with a single 8-pin connector (no 6-pin) for moderate overclocking. I have no interest in going higher than 180-200W at the most.

Yea, I dont understand going from a single six pin to 6 + 8. How much more juice can you pump into the card?

It would be pretty disappointing on a price/perf basis. The 290/290x were regularly available in the US for $200-$250 as far back as late 2014. And those cards also overclocked 10-15%. At $200, the RX 480 wouldn't be moving forward on price/perf much at all, even if it's a better card in many other respects (power, tech, etc). But maybe that only applies to US consumers who have access to cheap AMD cards.

The reason the price was so low was because people avoided the reference design like the plague due to insane noise and throttling. The aftermarket cards always held good value.

I think you can't really expect an OC beast on the stock card. The max I think you will be able to push it is 1400, anything extra will be just gravy on top. But looking at the OC tool looks like it is very customizable.

I think we can expect some very good clock rate from beast mode cards with good cooling. if they are stock 1500 I would expect around 1600 max on those cards. I am looking out for those as well.

Only 5 days left. I think we will hear all about the custom models from all over the place soon. AIBs wont hesitate to pump people up if there are are heavily OC cards coming out. Power color is already touting a new devil series card. I expect decent OC from these cards. They might be the first one to have the so card beast mode card.

I don't believe AIB cards would somehow offer vastly better OC. It's not normal from AMD, their reference cards aren't limited by power or PCB components, just cooling.

Now if someone who cranks the fan to 100% on the reference and +100mV can't get to 1.5ghz, it's not great. Esp if AIB cards come 1.5ghz stock. It would mean the bios is artificially limited and the only reason for that, is to have a artificial market segmentation. ie. $299 expensive OC AIB models to make the AIBs happy.

all cards on the table
no ace in the sleve
Hard to say whats going on as we havent even seen the launch driver yet.

If AMD is going to have the upper hand on this market, we will see the usual stuff we normally see from Intel and NV. "Artificial" segmentation in spades, crappy value whatnot. Nothing new here.
I assume they have the opportunity via software to control how the die is used. They claim they will go up to 300 usd. And man, its a long 50% uplift from 200 usd, and ram is not going to make that difference. They need some performance imho for that long stretch.

Yes indeed. When they announced up to $300 price range, it can be only two options due to the huge price gap: 1) Full Polaris 10 chip or 2) Artificially enhanced AIB high-clock variant. Since they only have the 2304 SP variant launching, $299 RX 480s would only make sense with #2.

The way to artificially gimp the cheaper $199/$229 SKU is to cap it via bios with a low TDP limit, as soon as you OC you hit that and it throttles down.

It would be a bad result for gamers and particularly enthusiasts who enjoy manual OC.

Bios unlock/adjustment havent been that difficult before.

Agree. Its not problem because there is a world of difference from users installing a new bios violating guaranties to just ajusting a slider in some properties. Bios hack adresses a very small audience, but anyway its amd controlling if that bios hack is possible.

Where exactly does this TDP limit info come from?

It's just speculation.

Because the same source that claims the reference RX 480 doesn't OC well, have said every custom RX 480 with a better PCB stock clocks 1.5ghz.

To me, that doesn't make sense because 6+1 power phase on the reference is plenty for what is a card that uses ~100W in gaming. 1x 6 pin also allows up to and even beyond (good PSU) 150W. There's head room there for the chip to hit the same clocks as the custom board. IF it does not, according to these rumors, it only means it's artificially gimped via the bios.

So we have somewhere around ~1270 stock and ~1350 overclock, and we speculate that AMD TDP limit might be so tight that even a 6% overclock might hit the power ceiling?! If that would be the case, prepare for the card to throttle at stock turbo clocks, because power variation alone can lead to short term spikes like this.

Why would you do such a poor job and potentially gimp your own product (launch) when you can set up more accurate temperature limits along a configurable TDP, and let the AIBs prove their worth by providing added value where they're good at? (stronger quiet cooling) The cooler itself makes for the best hardware limit!

Nope. Speculation was that Vdd - Vmin spread is very small due to adaptive clocking. This has no relation to TDP limit.

Because they've learnt not to make a crap reference cooler since the 290/X debacle.

I've seen the RX 480 benched live, low 70s temps and quiet. The cooler is in no way the limiting factor, if it can't OC well, ie 1.4ghz tops, on the reference card but runs 1.5ghz stock on custom cards, it means it's artificially gimped. That's all there is to it.

They did this before, Nano had a very tight TDP regulation via the bios. It will throttle any OC unless you manually up the power limit which goes to 150%. Now, AMD could simply pull a fast one, and remove that option or limit it to 110% (NV's cards have 107 to 120% TDP settings). If they enforce a 110% TDP limit, then yes, as soon as you OC, it will throttle and so you can't get high clocks.

Now, ofc, the rumor could be full of BS. It could well be the reference card OC just fine with +vcore +power limit. Or it could be that Polaris is a crap over-clocker.

Since we're speculating, I'm basing it on the source with the claims reference cards are limited in clocks while custom cards come with 1.5ghz.

Since EK is going to release full WB for RX480 soon, anyone wanna speculate how far can it OC under water with this 6 pin card, if I'm not wrong EK RX480 WB is for reference card.

This "crap oc" rant is overblown. Both AMD & Nvidia have gone to new and smaller gpus (14/16 respectively vs 28) and have brought them out stock at fairly high clocks with very good performance.

The difference in OC potential could also be due to AMD giving the best binned chips to their partners and keeping the ones that don't OC well for themselves. Not every Polaris die is going to be capable of 1500 MHz, but if all of the CUs still work it can still be a reference 480.
