The cost is a factor but imagine we had the die shrink and like you demonstrated a few pages back tonga would have to sell for £130-£150 and full tonga 3/4gb depending on memory bus £160-£200. Meaning the 390 would be in the £200-£300 mark again, but with a smaller die and substantial power savings.

If you owned a 6970 you wouldn't have really bought the 7850-7870 but it was a midrange die shrunk new gen that replaces the 6950/70 with another tier above 7950/7970.
We should see the same again but the lack of die shrink is a bummer.

First i'll get the irony out of the way

i had a Saphire 6950 and bought a Gigabyte WF3 7870 for £220, last Gigabyte card i will ever buy.... i replaced that with a Powercolor PCS+ 7870XT.

If AMD are die shrinking and retailing at around the costs i laid out they will no doubt attract new buyers, especially with power consumption numbers being all the rage.

If they are 'cheaper for the higher tier' then yes quite a lot of existing AMD owners have an upgrade path.

But its a long way from what AMD need to do at this point to put themselves back on the map, they need that £300 to £600 range that competes directly with the 980 to GTX Titan-X

I remember that 7870 lol!
my post above agrees too, £300-400 for me.

Since when did Silverstone became a piece of crap?

Yeah, i think i remember you do, what a dog that thing was, and was it any wonder, the thing used to flex picking it up, they all had that kink in the PCB where the Memory IC's pushed it down from the IC's cooler, which in turn rested on the corners of the IC's, the PCB was like a sheet of cardboard. oh and it was blue.... to top it all

Martini1991 · 8 Jun 2015 at 18:36

I'm confused.
What's a piece of crap then

?

Why's it a piece of crap?

I've got one of those Corsair RM 850W Modular jobbies, reviews like no ones business.

What you have is a proper PSU, this is one of those mini things.

Ok it might be pretty good, i don't know that its a piece of crap, but i wouldn't trust it to run my rig, look at it....

SFX PSU's seem fine to me (Form factor, brand is just coincidence)

All made by SeaSonic

Ignoring size and the lack of cooling that might imply with the confined space and small fan and the small form factor components used to make it possible.... ignoring all that, a 600 Watt PSU with 80% efficiency is not something that i would trust to run my rig, it might be capable of doing it in full size form but at high stress.

Its why i opted for a large 750 Watt XFX (Also SeaSonic) with a 140mm fan, still going strong after 3 years of almost constant use

humbug, remember small doesn't automatically mean its crap.

I go for more power myself, I had an 850W XFX, but it died, and I have no idea where I bought it.
It was during bank holiday, no to go to flipping maplins, but the price on the PSU was good (If you consider cheapest, but still an overpriced PSU to be good), so I either paid over the odds for a crap PSU, or paid loads (But less than online) for a good PSU.

Don't worry Martin he's backtracking.

If a PSU adheres to power delivery standards and can deliver enough power to the motherboard (8pin) along with the rated 2x 150w per 8pin PCI-E connectors, it should be able to handle any card that has up to 2x 8pin connectors. If it can't, it is not built to that spec and should not have those connections. It's said that the PSU "can provide enough juice to handle even an Nvidia GeForce Titan X GPU along with a powerful processor." so it's unlikely that Fiji will be more demanding even with a bigger die, given the energy efficiency gains HBM is supposed to deliver.

If we play the scenario the other way round and the Fiji card is attempting to draw more juice from the connectors than the specs allow, AMD would be putting themselves into a minefield and this would result in a pretty big PR blunder as it would add a barrier to purchase for those without obviously over-spec'd PSUs.

Have you got a link to the comment that was posted?

Interesting, read down to the 3xx cards. Bogus or....

Speaking of PSU's how long do they typically last? People say they lose efficiency over time but from what i can gather it's usually overstated quite a bit, and in fact it's only a small loss at least on the quality ones.

Still using a 750w Corsair from 2008, transferred it in with my x99 stuff.. would it still be safe to use with a new high end GPU?

The main issue is that capacitors tend to swell and eventually pop.

Over time, or dependent on load?
