12nm polaris 30 rumours

The price I showed was Australian dollars which includes Tax, when I check the AUD price for your link I get $618 including tax..
 
FF XV Possibly the worst game you can bench with. Results are very inconsistent and its an nvidia title.
 
I wonder if Vega is being discontinued. I noticed that there are no Sapphire Vega cards listed anymore on Newegg. It seems there have been these on and off sales to clear out inventory, now the inventory is gone.

Look, AMD really screwed up with Vega as a product. It doesn't make sense that they shipped the Vega 64 at 1.2v for the max boost clock. Mine runs maybe 50 MHz slower when set to only 950mv. In that situation it's pretty close to the efficiency of Pascal (I'm in the process of running some tests to compare the two). Being able to cut down from 1.2v to 950mv is insane. That's 20% less voltage. Now, my card may be a "golden sample" or something, but a lot of other people are also reporting being able to cut voltage by a lot, as well. Meanwhile, at 1.2v Vega looks like ****, with power efficiency totally out the window.

I'm guessing that the problem was a combination of the large die size, and the cost of HBM made it so Vega had to compete at the high end in order to be profitable. To that, AMD decided they had to throw efficiency out the window to post competitive results (didn't want to be 10% slower), but it just seems stupid to me. In the end it paid off for AMD since Vega just got purchased by miners anyway, but that was really just a fluke.

It sounds like Vega 20 isn't coming to gaming products, but I don't fully understand why. Nvidia gave AMD a gift by not improving performance by an significant amount with Turing. I don't see any reason why a Vega 20 couldn't compete with the 2070 and 2080, while having much better power efficiency just from not being run at stupid voltages. I wonder if Vega 20 ends up stacking up well if AMD's plans can't change.
 
I dont think we'll get anymore hbm equipped gaming cards. GN said current prices for 8GB of HBM is 150$ just for the vidram. Thats nuts from a BOM POV.

I think amd was losing money on them. They have to move to gddr5x and 6...

Hay, can you outline how you're making this adjustment? I'm mostly just curious, but it's fun to tinker with settings! Thanks!

You use wattman push the slider to custom and tinker all you like. Apparently the floor for the voltage is whatever you set the HBM to. You can set P6 & P7 lower but it will default to the HBM voltage thats what I'm reliably informed. You can use Radeon overlay to display tons of info so it's quite easy really.

You can make the adjustments using Wattman, however you're limited in how low you can. The memory voltage is sort of the lower bound, but there's actually a bit more to it than that. Without using a registry power table I wasn't actually able to lower my voltage lower than about 1050 mv, regardless of what I entered in Wattman. The issue is that the lower P-states that you can't change in Wattman also serve as another floor. (The interactions are sort of complicated between the different core and memory P-states and it would be a longwinded post to explain all of it.)

The easiest way is to do as LordHawkwind said and change your HBM voltage in Wattman to say 1000mv, and then set P6 and P7 to 1000mv. However, this will also cause your memory to clock up to full frequency at a much lower P-state than it normally would (shouldn't affect anything at full load, just maybe a little more power consumption if playing an older or graphically light games). Also P5 and lower end up using more voltage than P6-P7 which has some weird results (more power consumption at lower usage).

If you have a Vega 56, because the voltage curve is less aggressive you might be able to go all the way down to 950mv (900mv?) without having to modify the registry. You can use MSI Afterburner's overlay to see what voltage is actually being applied (it will be about ~50mv lower than what the actual setting is).

Modifying the power table in your registry is actually the better way of doing this, and it's not that hard using OverdriveNTool. Unfortunately, I don't have time to write up a comprehensive explanation about how to do it right now. In short what you'd do is save your card's BIOS to a file using ATIFlash, run OverdriveNTool as administrator, right click the top bar and load the power table editor, import the power table from your BIOS file, then you can edit everything there and apply it. I suggest saving a copy of your original power table as a registry file first in case you want to roll back to it. Also, don't set the voltage for any of the P-states less than 800mv; don't set any of the voltage for the lower P-states to the exact same voltage or the card may get stuck and not be able to clock down (add at least 5 mv per state). If you make a mistake and can't load into Windows without crashing, then load in safe mode and apply your original registry file to fix it. Alternatively you can uninstall the driver using DDU and then reinstall, but that's more of a pain.

I guess reviewers have them in hand already.

Ya 500$ CAD is too much. 400$ for the top end GTR type. Leaks so far show the 590 can clock pretty high. One model was clocked at 1680 core. If they added better ram to that and after seeing some benches it may become a good choice for midrange.

Im kinda impressed how the 2 year old XFX GTR RX 480 (1338 core) I have does 1440p...

Id buy a custom XFX GTR if it had faster ram and clocked 1700+...
 
Couple days before reviews but one site has a rumor that the new chip is surprising:


https://www.reddit.com/r/Amd/comments/9whxvl/rx_590_performance_dubbed_surprising_by_babeltech/

In the second to last sentence of their VR roundup between the 1080ti and 2080 BabelTech lets slip that the RX 590's performance has surprised them. Given all the other leaks so far it doesn't seem like there's any room to be surprised. Consensus appears to be a refreshed 580... What do you think surprised them?

That guy hacked the website I doubt it'll be 2000 core. Probably just placeholder info tho one guy on reddit said the HIS RX 480 was the fastest one at the time I thought it was the XFX GTR which I have.

Gamepackage tho looks to be great:


Red Devil RX 590 comes with Resident Evil 2, Devil May Cry 5 and The Division 2
