Radeon RX 480 "Polaris" Launched at $199
- Thread starter Kaapstad
- Start date
And according to that then if a 480 is 390x perfromance, a 20%+ overlock puts it exactly at 980ti/titan stock speeds. Giobbo says it doesnt even come close to a 980ti even when overclocked.
Ergo its not a 390x card at stock speeds.

Check me out in that benchmark list..
318. Score 1017, GPU 7950 @1200/1650, CPU 2700k @5.026, MyBrains

I'm still highly skeptical of this, and want to see independent figures.
If Polaris 10 was scaled back up to 28nm, it'd be larger than the 390X AND is meant to have IPC improvements.

Those 7970s and 7950s are still good cards.
I gave my 7970s to people at work for their kids to game on and they are well pleased.
True but then with a 20%+ overclock it should match 980ti/titan performance and Gibbo says thats a crack dream.
SO you cant have it both ways. It either isnt a 390x performance at stock or it doesnt overclock. OR when overclocked it matches a 390x.
No it doesn't.
At 1080p the 390X gets 70%, add a 20% overclock, even with linear scaling which never exists =1.2*70 = 84%, still 16% slower than the 1070.

yeah my 7950s were my fav cards ever. Beastly overclockers.
Except in those charts links the 980ti only gets 82%
AGreed it will still be slower than a 1070 though
A 390X needs about a 40% overclock to match a 980 Ti.

Yea still going strong, was gona go for a 480 but i might just wait a bit longer for Vega instead now the hype train has crashed LoL
Unless the full answer is something more subtle. That AMD have improved performance per watt hugely, but even overclocked it doesn't draw that much power.

He's talking about a 980ti and not a 1070. The 980ti is around 20% faster than a 390x at 1440p.

So if the RX480 was 390x speed and a decent overclocker it should be able to get somewhere in the region of the 980ti. Tbh if Gibbo is used to the charts around here where everything is overclocked then a RX480 won't get anywhere close to the cards in the charts.
How? In thosescharts a 390x is only 18% slower than a 980ti. I know you dont get linear gains but I would have thought a 20% or more overclock would put it in the ball park.
Agred But now Kaapstad is saying it needs a 40% overlock to match a 980ti and hence a80% one to match a 1070
On that basis even two 480s wouldnt beat a 1070.

Yeah but Kaapstad is hardcore Nvidia, literally any sniff of news which swings that way he'd use the extreme end of any figure to bend the argument his way.
To be honest mate i'd just ignore it and wait, we'll all find out soon what the true performance is. Lets all hope AMD can pull it out of the bag and add a bit of competition to the discrete GPU space. It sorely needs it.
