Nah not really. HBCC tech reduces vram requirements by half or so, in part because HBM2 has lower latency than gddr5 etc. Recal Fury x punches well above it's weight with 4gb hbm and doesn't have HBCC.

I don't see halving the ram making more than 10w of difference. Having tile based rendering working in the driver might make a small dent as well (or more likely may just help keep clocks closer to boost). That was a feature nvidia went to great lengths to conceal that was part of what made maxwell more power effecient than Keplar despite being on the same nm process.

Didn't the Fury cards have this same problem? heaps of power needed for very little performance at the time.

No not really to the same extent. Fury x went up against the 980 ti and drew a little bit more power but not a huge.
http://www.guru3d.com/articles-pages...-review,9.html

It was slightly slower at launch overall, but now beats a stock 980ti.

More a case of newer Nvidia cards drawing less power than they used to, and AMD vega is drawing more

For those interested in what actual pro cards are like, Wendell has a cool video up looking at the WX7100 (RX480).

Dunno if it's been posted already but PCPerspective have a review of the watercooled FE card.

Has a weird cooler design to.

To me that looks beautiful, just like this did:

Looks like it's pretty much the same kinda design really .

In there testing the watercooled version was basically on par with the 1080 for games aside from GTA V which it fell 30% behind in and over all it was 30 - 40% behind the 1080Ti but that's not big surprise.

Now I wonder if the RX version will be the same or if it'll be a little faster. The power draw is a bit scary though.

Reminds me of the earlier days when AMD and Nvidia were actually even competition and AMD cards always seemed priced bit better but hotter/hungrier/noiser and I always referred to it as something along lines of:

Nvidia = v8 naturally aspirated with 300kw
AMD = inline 4 turbocharged with 300kw but running 20psi through the turbo to get it..

or the TLDR version: AMD has its hardware at the limits to keep up with Nvidia.

Not sure if this is case with Vega but is seeming so.

Just here to say 20psi isn't much depending on the car.

I really wanna see where the RX sits because the FE water, for a lot more money, doesn't have the gaming chops.

Sorry only nvidia have turbo lag (texture load issue).

Maybe get it right next time as V8 dont have lag.

You might say AMD are like Tesla, you know, the future not the old DX11.

I never implied v8's have lag.. it was to show that Nvidia got its performance from a solid foundation. v8 with 300kw where AMD tacked something (turbo) onto a weaker foundation 4 Cyl and pushed it pretty hard (20psi)

edit: I think I get it now, you say Nvidia has turbo lag via texture load issue.

What cars run more then 20psi boost stock? Not a great deal I would think.

Anyway I am not saying this is case for Vega but some early signs of it.. But if the price is right, a nice water block + beefy PSU will save the day.

A lot of euros. All golf gtis are around 22, golf r is 24, Audi S3 is 24 etc etc

Really irrelevant to Vega at this point though

I don't experience this with my Fury X, tell me your secret? Because mine chokes like a little bitch when going above 4GB VRAM, fallou4 is a good test., And my 980ti beats it in most games, (FO4, Skyrim, Andronmeda, to name a few).

Anyway I really fear the release of the RX Vega now, perhaps they can make the lowest end version perform good but each passing day kinda pushes me towards saving up for a mini 1080ti card once NVIDIA slashes the prices by $200aud. (they will wait until after vega). I really wanted a freesync card, but looks like I will need to skip AMD this generation until they figure out how to make them small and cool again.
