AMD Polaris Thread: Radeon RX 480, RX 470 & RX 460 launching June 29th

If it's 390 performance only I wonder if it's worth it for me to upgrade.

~110W might be hitting the default (0%) power limit. I remember others reporting about a similar power consumption.

It might only be drawing 110W at stock clock speeds and voltage, but it might also be the case that it doesn't have much OC room without increasing the voltage, but also the case that the chip is already close to the voltage limit as well.

If that's the case you end up with a chip that draws low power, but neither has much room for an overclock or an overvolt. Presumably, there are going to be some chips that can hit the stock clock speeds at lower voltage levels, so those are going into the bin that gets used for the alleged $300 AIB cards.

It could be a case of something that gets better as the process matures at GF or one where Polaris should have been a bigger chip given the limitations of the process.

I have a 7950, and plan on upgrading. Although I think I will wait for AIB cards. A 390X is a noticeable amount faster than Tahiti.

Yea I have no idea when AIB cards will be out. I'm pretty sure it's a decent amount better than my current card.

If it's 390 level performance then you should get an increase in performance of about 40%. If it's 390X level performance then the increase should be about 50%.

This is of course assuming that you haven't overclocked your 7970 GHz.

Yea I've never over clocked it. Didn't really need to as long as I've used it.

I can say that an RX480 clocking in at 390 performance is pretty embarrassing. Considering that a straight up die shrink of the 390x would end up being smaller than 232mm (~200mm), that would mark a significant regression in performance.

The RX480 has a memory bus size 2X smaller, too. That should allow for more die size for other things. Plus, the RX480 is clocked at 1266mhz, which is much higher than the 390X's 1050mhz. There should be no reason for the RX480 to be slower than an R9 390X.

Ah sorry. Was sure Guru3D was hosting them.

 

[BlitzWulf]

Where is everyone getting ~390 perf from?
Was it the Steam VR test or all those gameplay videos with weird settings?

I just want to be clear 390=5.1 Tflops RX 480= 5.8 Tflops ,are people really suggesting 12% decrease in perf/flop from Hawaii so casually?
Am I the only one that thinks that's ludicrous?
This isn't a hype train it's a hype rollercoaster,every hour the 480 goes from being 390 level to FuryX and back again.

I think at this point, most of us are just having fun with rumors and speculation, don't take it too seriously.

 

[StrangerGuy]

While we don't know the exact performance yet but even if it is just ~390-390x level as soon as the 230$ RX 480 is available I think most others (hawaii and 970) would mostly be irrelevant from a new buyer's perspective,be it VRAM (8G vs 3.5 effective),power consumption,ports or some better features.
Also AMD should release rx470 as soon as possible as it could be even better value for most buyers. Effectively they would have no competition until gp106 drops off(and is competitive at comparable by price/perf and other metrics).

Yeah, 390X level perf @ ~100W is already a godsend to me considering how annoyingly hot my 7950 runs in an ITX case. Won't want a 970 even if was slightly cheaper.

Speaking of the RX 470/460, won't be remotely surprised if they can be powered entirely by the PCIE slot in reference form.

 

[parvadomus]

LOL I didnt expect RX480 to feature 32 ROPs only. Wasnt that their bottleneck with fiji?
If this trend continue expect Vega to be 16 ROPs with 20 TFLOPs compute powa XD

 

[Mopetar]

Something would have had to go extremely wrong with Polaris if it's only getting 390 performance.

It has 90% of the shaders at 126.66% of the clock speed. Ignoring the differences in memory for time being we should see a ~13% performance improvement over the 390 when we're not bottlenecked by the memory or some other aspect of the hardware that's cut back.

 

[agfkfhahddhdn]

We need some catfood bets to really make it fascinating.

Meh, I really don't have anything riding on the success of this card. If it's good enough, I'll buy it. If it's not, I'll buy the 1070. The 1070 is more expensive but it'll probably last a bit longer. I try not to think about any of that though because it's so much more fun to get riled about about baseless speculation.

Yea I'm just going by what everyone's been speculating here. I hope it is more because I will be giving my card away soon. For $250 can't go wrong in getting one and waiting for Vega.

NVIDIA and longer can't go together. Just check how Maxwell is being abandoned.

That was my thought too until I did some digging around and found out they won't support it for long term. It may be great now but I guarantee I won't be able to use it for 4+ years like my current card. Nvidia path seems to be upgrade often for best results.

Fiji was not ROP bottlenecked, it is front-end bottlenecked.

 

[dogen1]

Technically every GPU is rop bottlenecked sometimes.

But yeah, fiji is probably held back more by other things.

If history repeats itself, the 1070 will get progressively slower as time moves on. nVidia has no interest in updating drivers for older cards.

Well yes, but for Fiji that is essentially in certain 4K+ resolution corner cases... for most people, under most conditions it will not be ROP-bottlenecked.

We'll have to wait for reviews to see where the bottleneck for Polaris will be. There are always tradeoffs in chip design.

I would actually argue that AMD should do the same. It would certainly force earlier upgrades, which would be beneficial for profits.

That they haven't has been great for owners of AMD video cards, but if I was a shareholder I certainly would want them to be pushing a more frequent upgrade cycle.

Well, anytime you're drawing shadows too lol.

 

[Face2Face]

Alright guys, I did a redo on the comparison video. I tried to bring my 5820K down to the i5 6400 level. I disabled two cores and Hyper Threading. I also left the CPU at stock speeds, and removed two DIMMs. The 8GB of DDR4 is running at 2133MHz as well.

I also down clocked my GTX 970 a bit to 1330MHz, so it's a more realistic comparison. I don't doubt GGPC's RX 480 isn't real, but without review drivers there could be a lot more performance on the table? Also, I unlocked the limitations, so they are both running at the same graphical settings.

anyway - here it is.

If it's 390 performance only I wonder if it's worth it for me to upgrade.

1070 is ~ 2X faster than the 280X/7970Ghz.
-> $420 / 100% increase in performance = $4.20 per 1% increase upgrade

RX 480 ~ 390X is 49% faster than 280X/7970Ghz.
-> $240 / 49% increase = $4.90 per each 1% increase

If you look at it like that, 1070 is a better upgrade for you if the intention is to keep the card for 3-4 years and esp. if you want to upgrade to 1440p this year. Vega may not be out until late Q1 2017.

You also mentioned that you will pass your 7970Ghz to your brother. That means when it comes time to upgrade the 1070, you can pass that card to him too, in turn making his upgrade from 7970Ghz to 1070 bigger too. If I had a little brother that I passed on my GPU, I'd get the 1070.
