::: Radeon Fury / Fiji XT diskussionstråd :::

Är väldigt intresserad av detta men frågar mina kära sweclockare ifall pci-e 2.0 x16 kommer att strypa kortet? Sitter på en z68 bräda som stöder 3.0 men måste då flasha bios och trycka på en ivy bridge då jag har en 2500k @ 4,5 GHz atm. kommer det att vara värt eller bli strypt?

Tyckte att gårdagens lanseringsshow kändes ganska cosy, lite personlig. Kändes som om man kom AMD:s ledning och ingenjörer lite närmare, på nåt sätt. Nvidia känns som ett större (obvious...) och ett mer opersonligt företag, imao.

Har samma känsla nu som när man kände att SAAB (R.I.P.) var det mer naturligare valet än Volvo.
De kändes då lite mer innovativa och mer personliga. Precis som jag idag känner gällande AMD vs Nvidia.
Har alltså ingenting emot Volvo/Nvidia, men SAAB/AMD tilltalar min personlighet bättre.

Känns faktiskt som om AMD har nåt på G nu och jag kommer, med största sannolikhet, "investera" i ett Fury X-kort.

Ps. Kör idag Volvo och äger ett gäng Nvidia-kort (förutom mina två R9 290 i sign...) Ds.

Jag satt precis och funderade på det, det är väldigt få ROPs jämfört med Hawaii. On par med tahiti, men färre än Hawaii

When I asked Macri about this issue, he expressed confidence in AMD's ability to work around this capacity constraint. In fact, he said that current GPUs aren't terribly efficient with their memory capacity simply because GDDR5's architecture required ever-larger memory capacities in order to extract more bandwidth. As a result, AMD "never bothered to put a single engineer on using frame buffer memory better," because memory capacities kept growing. Essentially, that capacity was free, while engineers were not. Macri classified the utilization of memory capacity in current Radeon operation as "exceedingly poor" and said the "amount of data that gets touched sitting in there is embarrassing."

Strong words, indeed.

With HBM, he said, "we threw a couple of engineers at that problem," which will be addressed solely via the operating system and Radeon driver software. "We're not asking anybody to change their games."

Borde vara 24 Juni samt 14 Juli.

Hur värt lär det vara att slå till på en fury (utan x, här är vi inte rika inte) istället för en 970 eller en 390x då? Blir ju någon tusenlapp mer drygt men det kanske är tillräckligt stor skillnad för att det ska väga upp?

Bra inlägg från: https://forum.beyond3d.com/threads/spinoff-4gb-framebuffer-is...

6-8gb (depending on what your bus size is) is really better if you intend to keep your card around for a few years or more.
Sure, if you're happy running your game at 15-20 FPS.

Honestly I'll be surprised if more than 1% of games in 2-3 years will effectively require more than 4 GB of memory. We're still going to be mostly limited by console requirements which means games that exceed that is going to be exceedingly rare. Games on consoles also need to store system RAM and VRAM in the same pool of memory unlike PC. So it's unlikely a game on console will exceed 4 GB of VRAM usage.

As well, in 2-3 years, the hope would be that DX12 will be more prevalent. And Sebbbi has already given the viewpoint of a current developer of many memory saving tricks that games can easily use to provide far greater texture detail than exists currently with less than 1 GB of VRAM.

Of course, more memory is never bad...unless it doesn't get used and only inflates the price of your graphics card. But until such time as 4 GB becomes a limiting factor it's all supposition.

Yes you can run into limitations with carefully manufactured tests now, but then what does it get you. Even the Titan X with 12 GB of memory can't even reach 30 FPS in a situation where it can actually use more than 4 GB of memory (http://www.anandtech.com/show/9306/the-nvidia-geforce-gtx-980-ti-review/13 ). Seriously how much future proofing are you going to get with memory when your GPU is going to limit you. Especially when the inflection point for increased memory useage is consoles which aren't going to be getting a hardware upgrade for another 4-7 years.

Yes, there will be the 1% that have to run max everything mods in something like Skyrim. In which case, no, the Fury card isn't going to be for them.

Remember when 2 GB cards launched and 1 GB cards were considered idiotic to buy because even those no games used 2 GB on the video card, it was a way to future proof? And by the time 2 GB was actually used in games, all those 2 GB cards that launched back then were too slow to actually run those games with max IQ? Yeah that future proofing worked really well.

Of course, perception is always different from reality. The perception that more than 4 GB will make a current video card future proof will discourage people from getting the Radeon Fury. The reality is, that by the time it's a serious limitation, it wouldn't be fast enough to run those games to the satisfaction of anyone needing more than 4 GB. Likewise, by the time Titan X can take advantage of that mass of memory it has in games, it'll be too slow to satisfy that people that bought it in the first place.

TL: DR - By the time greater than 4 GB of memory is critically important. Almost everyone that bought an enthusiast card this year, will have already upgraded their video card...making it a moot point.

DX12 can bring a lot of exciting changes to the world of graphics rendering in games. Increased VRAM useage likely isn't going to be one of those.

HD4870 hade 150% fler streamprocessorer än HD3870 men samma antal rasterenheter. Dom hade dock dubbelt så hög effektivitet jämfört med HD3870. När man ser på bandbredden och minnestypen, samt snack om en ny typ av färgkomprimeringsmetod så kan vi nog lätt sagt snacka om rejält omarbetade rasterenheter i Fiji.

Jag konstaterade just att Fiji har varken fler eller färre.

Jag konstaterade också just att antalet inte säger speciellt mycket och att dom förmodligen är rejält omdesignade vilket jag också tog ett lysande exempel på och hur mycket det kan göra prestandamässigt mellan olika generationer under vissa scenarion. Resten är bara spekulationer.

Antingen förstår man eller så förstår man inte. Du kommer in i min tråd jag gjort och tror dig veta saker du inte har en aning om och börjar en pajkastning om saker som är konstaterade och logiska antaganden gjort av mig. Bara komprimeringsalgoritmen från Tonga är en av sakerna som med stor sannolikhet kommer implementeras men hade kunnat gå in på djupet och hålla på hela dagen med dig.
