[Rumor] RX 480 Overclocking 1500+Mhz

[Bacon1]

I am aware of that, i was just pointing out that cards on 1500MHz+ will not get high perf/watt. There will be GTX 1070 eventually sold at $379 and those cards will be much better than a OCed Polaris 10 for only ~$80 more.
What im more interested at is the performance of the vanilla $199 4GB RX 480 at 1400MHz, can it come close to GTX 1070 at 1080/1440p ??? At those clocks perf/watt should be very good and the price/perf the best in its segment by far.

"Only ~$80 more" is 25% more expensive... Add in taxes and you'll get closer to $85-90 more.

If 1.5GHz+ cards will increase voltage to pass validation, say good bye to perf/watt.

Those cards may reach close to GTX 1070 performance but at an increase in power consumption, perhaps even more than GTX 1080.

I'll brace for the self righteous indignation when O/C'ing blows the perf/W metric out of the water.


I'll be interested to see what the plain Jane $199 model will do. That could end up a bigger perf bargain than anything in recent memory.

Anyone who OC's is obviously waving good bye to perf/watt. The point is when you can buy a $300 part that competes with a $400 one a few $ per year for the extra power usage is well worth it. Plus you can use that extra $100 towards a nice new freesync monitor and have a much better experience.

Your post is the essence of over clocking. Pay less and hopefully get to the next level performance wise. "Damn the torpedoes, full speed ahead.

I read a rumour that 1700 might be possible /s

sorry im all aboard the hype train to polaris town!

I recall seeing a 1660MHz lock (read max ceiling) in the Linux driver FYI.

 

[3DVagabond]

Total DominATIon if that is accurate.
anything below a 1080 will be a 400 series card

Are you new to this?

There are plenty of people who will pay more for less performance from nVidia. Any metric. Find one. And if nVidia is better at least 1/2 the people will spend more for it. People were still buying 285's instead of 5870's, 580's instead of 6970's.

This. Even if the 480 matches the 1070, the vast majority will still buy the 1070.

The 1070 is made by NVIDIA, so it's automatically superior and worth the extra to many people.

I don't agree with this of course, but it's hard to ignore when NVIDIA's market share is so massive, that games are developed and optimized firstly for NVIDIA cards, AMD come second.

1400Mhz is only 11% increase which is similar to what 1070 can do so both cards will keep status quo of non overclocked versions.

Right like all those people who were going to buy glorious Fury according to you posts on [H] before it released

480 won't come anywhere close to a 1070. I wouldn't even be surprised to see the 1060 be faster.

Keep in mind they were talking DX12 games. Nothing would surprise me with as poorly as nVidia does in DX12.

Faster than a 1070, WOW. you heard it here first folks, don't buy the 1070, wait for the 1060.

 

[sm625]

For the most premium versions, it makes zero sense to have a bios switch from 1266 to 1500. That is too large of a jump. If the card is binned and designed to run at 1500, why even have a 1266 mode? Why not 1400?

I don't believe the typical consumer is as loyal to nVidia as some of you all believe. If this all plays out the way it appears to be going from the leaks we're seeing, I think AMD is going to clean up with the 4xx series (which of course opens up the possibility of nVidia responding aggressively). Much of AMD's recent loss of market share has more to do with severe missteps early in a product's lifespan than actual deficiencies in the hardware itself. 79xx, 290, and Fury all were excellent products, Fury was simply priced too high compared to the 980ti. 79xx just didn't perform all that great right out of the gate and 290 reference cooling hung an albatross around it's neck throughout its life it couldn't shake even after far superior custom solutions arrived. Couple that with various software issues either real or perceived and you get the situation you have now. Assuming most of what we're hearing to be true though, it appears they are serious about turning this around, really serious. I'm pretty certain I'm going to grab a 480 for my mini-itx box, I'd probably replace my 780s in the 3930K with 480s if not for me already having the 980ti's ready to drop down to it once I replace them in my primary rig with Vega/big Pascal. I also think people are underestimating this built up anger over the ever escalating pricing of GPUs in general, particularly in the mid range products. Plus Average Joe probably doesn't give a crap about "nVidia" or AMD, Intel is probably the only name that means a hill of beans to him. Hurry up AMD, I'm waiting to throw a pile of money at you if Vega turns out as well at the high end as Polaris is looking to be at the moment.

 

[Head1985]

No1 will buy 1070 in whole EU because it cost 500+ euro and rx 480 will be for 250euro and if its after oc within 10% of 1070.

 

[William Gaatjes]

I will wait for the reviews. But it does make sense that AMD would give the customer the end choice to go for performance or low power use. This way, the claims about being more efficient in terms of performance/watt is not violated and the OC crowd can also feast in attempts to get the fastest polaris there is which AIB's will happily help to provide.
Of course there will be a hard limit. How high that limit will be , that for now is just rumors. But that number in the linux driver of 1660MHz is interesting.

I do wonder, the performance /watt number is about 2.5 . I am wondering that this may not apply at the max boost clock but at the base clock.
But then again, who cares. I do not. The card as a whole will be less than 150 watts for the standard version as limited by the single 6 pin connector + PCIe connector power.
(In all honestly, more power can be drawn for very short periods of time. But it would be a very unwise design choice.)

Well, having a preset 1500MHz position stops sites from unnecessarily maxing out the voltage and reporting stupid power usage @ 1500MHz. I've seen this way too many times. They max out voltage, raise the fan to 100% and complain the card is hot, noisy, and inefficient.

^ RX 480 running Overwatch, 1440p, manually maxed (one notch higher than Ultra) settings with 122% resolution scale. FPS locked at 70 max, it was constantly pegging at 69/70 with some dips to ~65.

Not sure about AVG FPS due to the frame rate limit. These leaks are obscure because of weird settings like 122% resolution & frame rate lock, preventing accurate comparison. lol

Also here: http://www.pcgameshardware.de/Overwatch-Spiel-55018/Tests/Benchmarks-Test-Grafikkarten-1197158/

I would say it's running well above 290X & 390X performance class.

 

[Shivansps]

6+8PIN? really?

 

[Silverforce11]

6+8PIN? really?

Yeah seems the leaks are saying Sapphire & Powercolor will have highly OC models. Though there's no way it will exceed 8pin limits, so the extra pins are just marketing gimmick like all the custom 1070 and 1080.

Suddenly "more power" delivery is seen as a good thing. lol

I had a 7850 with 1 6pin, it overclocked 40% and the power was not a limiting factor. That card as you know, is rated 150W and in gaming load, we're looking at ~100W. Polaris 10 looks to be a repeat, Pitcairn class chip, similar in size & power, low clocks to target perf/w.

 

[Shivansps]

The 6 pin its not going to limit OC, at worst you gona melt the plug and the cables, but its hightly likely you gona blow up the VRMs first(or the board circuits), VRM is what limit the power, and 6 pin is able to carry more than 75W whiout melting everything down, out of spec...

6+8 will drive max power way beyond the 300W capacity, thats just crazy as hell, a 8pin alone is more than enoght.

 

[Silverforce11]

RX 480 reference design: 6+1 Mosfet, good for 30 amps each optimal (most of the common GPU mosfets can get to 40 but it loses efficiency), thats 180 amps for the GPU itself and 30 for the vram separately.

It is over-engineered for it's power usage. That's a good sign, as these VRMs will run at very low amps and will be cooler.

The board has plenty of power headroom so overclocking won't be power limited. It will be chip limited. This is why I don't expect fancy cooler models to overclock better. Just quieter or cooler.

 

[Shivansps]

Then there is no reason of why a standart 480 couldt overclock to those level as well... at worst you gona see some melted wires.
Unless they artificially limit the max power on the vrms, i think it can be done on firmware.

I do want custom models, the blower designs bring me nightmares, i do remember the reference 4850 and 5850, no thank you.

 

[boozzer]

Quieter is what I want the most. behind perf/$

They can simply limit the max +vcore you can go on the reference bios. This allows AIB custom cards to ship with a better bios allowing higher voltages. This would be an artificial limitation, but done to create a product differentiation. AIBs would love that.

Something to think about:

http://www.hardocp.com/article/2013...directcu_ii_video_card_review/10#.V2Xfx7h97AQ

7850 30% OC only increase total system power by 25W.

That could be easily fixed using another bios, but if they limit it on PWM IC firmware, we are just screwed.

Heh no way on IC firmware, that's too much hassle for mass production cards. A bios is much easier with max voltage cap in place.
