The Fury(X) Fiji Owners Thread

1)btw, its possible get from AMD license to creating non reference version of Fury XT cards? (or it is only for light brother ,-) )

2) what about software with unlock voltage? I believe, it must be exists. As some software for AMD internal using (example as Hotdog 15h V0.0X stress CPU test)?

1. no.

2. coming from third party in a few weeks.

Patience my padawans.:D

Would AMD been not been better going a normal air-cooler & getting the pricing more competitive verses the 980ti cant help but think this...

Don't think so. It's so long overdue that AMD reference cooling is cool and quiet rather than the nightmare 95 deg hoover rubbish they were releasing before.
I even think it's worth losing some pricing edge for, it's about reputation & the long-lasting impression of the card.
Not to mention, being able to buy the cheapest one & know it's 100% good cooling.

Interesting stuff about the frame buffer, so games that use over 4gb vram use system memory also, is that right?

What performance impacts will ddr3 and ddr4 have? Will 8Gb system memory still be enough for gaming?

DDR 3 at 1600mhz already has enough performance for the majority of games.
DDR 4 doesn't improve read latency over DDR3 so performance is no better under loads that don't require large amounts of bandwidth.

The latencies on memory chips are measured in clock cycles and the read times usually end up the same regardless of clock speed.

At the end of the day unless you are crunching gigs of data then 1600mhz DDR 3 is more than enough. Capacity becomes more important in the end. So just buy the highest frequency and capacity ram at the lowest price. you dont need to buy stupidly expensive ram unless you need the bandwidth.

this article helps explain showing the graph of cycles against frequency, showing the read latency in ns to be consistant as clocks increase.

Edit - If AMD Stuck some HBM2 on their Zen cpu's as RAM, it would have a far greater performance impact than DDR3 - 4 due to lower read latencies and the ridiculous bandwidth.

I think majnu was asking if the Fury X uses the system RAM when it runs out of HBM on the card. In which case you'd think DDR4 might help a little but I don't think either keep up with GDDR5 let alone HBM, so there'd be a noticeable performance hit I'd imagine.

I must admit i was very disappointed like a lot of other people when i saw the Fury X reviews but thinking about a few days after the event at 510 gbp there not badly priced. Yes you can get slightly faster 980 Tis for the same cash but only reference designs which by all reports stuggle with the heat output to get a decent 980 Ti like an msi gaming or EVGA custom your looking at nealy 600 at which point the 980 Ti losses it edge in terms of value imo.

Ddr3 and ddr4 will be far too slow for smooth performance. Yes, all cards use system ram when they run out of VRAM, going over the pcie bus is incredibly slow and causes stuttering. You don't get that form looking at average frame rates though, you need to analyze the minimum and frame consistency. GTAV and SoM when totally maxed are know to use more than 4GB of memory so it really isn't that surprising.
 
Amd need to step it up on getting more performance from the driver's, and the sooner that there's some voltage controls for the core the better. It has a lot of cooling headroom so hopefully more performance under the hood.
