might get a 390..

[TonyTurbo78]

build quality is improved as well, big brace on the 390's and the VRM is directly cooled unlike the 290's. Overally a much better product but yes not much difference in performance, the 390's maybe a few percent quicker.

All I know is I'm loving my 390 Crossfire, absolutely blinding fast, no problem in running anything so far at 1440p and Ultra settings. Even Witcher 3 I'm getting 80fps with everything maxed out apart from the hairworks stuff.

So far no proof of actual improvements has surfaced; clock for clock they perform identically to 290X, though it must be said that not all (relatively few?) 290X can reach the 390X stock memory clocks. Core OC-potential seems to be identical.

Yeah the 390x gets a memory bump in speeds, I jumped from a 7870 to the 390X so the jump is more noticeable for me.

Think mine has some coil whine though, only noticed it the other night when I was playing Neverwinter from GoG, wonder if the card is flying off into silly fps and the card is running full pelt. Might see if I can lock it down with vsync and see if the whine is still there.

try the frame limiter in CC should help with the whine as neverwinter doesn't need the stupid frames you're most likely pumping out LOL

Need Proof?
My 290X lightning could reach 1700MHz on memory , and that was the end of it.
Most 290X could reach 1500max, but some couldn't even reach that

This is a 390X Gaming

1780mhz on memory. Also they reach 1200mhz fairly easy on the GPU while most 290X can only reach 1100-1150mhz

Have you got any benchmarks of clock for clock or a link with some to back that up?

It would help if you read the post you are replying to. 390X reaching 1200 on the core let alone 1780 on the memory seem to be about as common as hen's teeth, judging by the evidence available.

Most 290X can't even reach the stock 390X memory clocks.

They are much much better with the memory...they reach what just the finest 290X could do, and usual 290X cards could do nothing close to that.

390Xs almost in all review reached around 1150mhz +-10-20..so with just a small voltage raise they are at 1200. I know many 290X which can only reach about 1150 with a good chunk of voltage.

 

[Martini1991]

Isn't the memory clocking more to do with Hynix's better binned chips rather than anything AMD has done?

Although I definitely don't doubt memory clock is better (Not that it matters)

But core clocking's basically the same, for as many samples you can show different, you can find as many that are the same.

 

[mururoa]

If higher leakage cores count as "having been improved" to you then that settles it then, I'm not in disagreement over this and hope to get a good one when my card arrives next monday. Clock for clock they are still 1:1 same as 290X, which (once again) was the point of discussion here.

I can get 1245/1700 out of my Lightning and 1180/1580 out of my G10 + H55 cooled card.

I thought the new 4Gb GDDR5 chips were to blame for the faster memory, they operate at faster speeds and lower voltages than the previous 2Gb GDDR5 chips. It is nothing to do with the actual Hawaii chip at all. Of course it has a knock on effect giving the 390/x more bandwidth and lower voltage required meaning they can clock them higher to give benefit at the same power levels.

The actual GPU hasn't changed at all.

Put it this way if AMD did respin the chip, why didn't we ever hear of any tape outs, and why in gods name doesn't it perform much better then the equivalent 290.
