Good good. Just seems people are comparing it with the X.

And it'll never be under 400 quid on release. Fredflint. The 290x was more than that on release and the 390 has new tech and a bigger core.

Then I will wait until it’s about £400 for the 8GB version. Will be interesting to find out what impact the new VRAM has on the PCB.

A good value for money ratio is around 80% of the performance for 60% of the price.

I'm getting the impression a lot of people would not be happy with that, though.

Depends on the Ti I guess. But you're right.

if we ever see it lol....it's going to come in between £600 and £700 I reckon.

So if I can decipher DM's post, theoretically a 390X with 16gb of HBM1 is possible right now if they stacked the mem and used the 4 slots?

I would say no, not at this time.

What I've been saying since the start is HBM 2 isn't relevant to any particular specification. HBM 2 say having higher density chips doesn't prevent an HBM 1 chip having higher density... HBM 2 is essentially entirely irrelevant to what can be produced today, everyone should entirely ignore it.

WIth a new memory the situation is that we don't know where they are at, with an established product we know when the first chip with X specs was available and thus have a good idea when the second chip and what it can do will be available. IE with a 2000 shader 40nm gpu you can make a good guess as to what you'd get at 28nm, circa 4000 shaders possible. Without the 40nm chip you'd be making a complete stab in the dark at what the 28nm gpu would have.

This is where we are at with HBM, we know the starting spec, but we don't know where the start of the development time line is. Lets say sticking 1GB stacks together to act like a 2GB stack comes 4 months after the first chips, and 8hi stacks comes another 4 months later, then 2x 8hi stacks together comes another 4 months later... then HBM 2 rated chips 8 months after that. Without knowing where we are on that time line you can't know when one spec will be available. When you know where we are on that time line, you can make good educated guesses at when the next thing will be possible.

An educated guess would be maximum capacity and highest speed come with a process node shrink as the image suggested with HBM 2 with 2Ghz spec and 4Gb chips listed as a result of a node shrink.

Personally I'd see the time line of HBM development as :-

HBM 1
1Gb/4 hi/1Ghz > 2 stacks merged > 8 hi > 2 8hi stacks merged

process node shrink giving HBM 2 starting at
4Gb/4 hi/2Ghz > 2 stacks merged > 8 hi > 2 merged > 4 hi 8Gb chips > 8 hi 8Gb

Due to high end product requirements, I would guess we start off effectively at stage two of that development cycle. Giving the 390x the option of 4 stacks and having 1 or 2GB per stack, giving us 8 and 4GB variants of the 390x.

Per capacity cost is higher for HBM than GDDR5, 16GB is both 100% not required for ANY gaming at all and a complete waste of money. It's likely also not ready yet.

Orangey · 27 Mar 2015 at 21:23

If they really do have a 60% uplift I'd imagine 16GB won't be far behind, if it can be done. You could probably trip 8GB if you try hard enough with quadfired OC'd 390Xs.

I don't think it'll be quite that high though.

http://hexus.net/media/uploaded/2015/3/140bf9ce-7f89-4c88-8c88-6830c8fee762.jpg

The first slide, reproduced above, compares the upcoming AMD Radeon R9 390X WCE with the current top single GPU card from AMD, the R9 290X. Atop of the table you see that the new graphics card offers 4096 Stream processors with an engine clock of 1050MHz offering a compute performance of 8.6 TFLOPS. The memory subsystem offers 8GB of the 2.5D HBM on a 4096-bit bus. Power can be supplied by either a 6-pin and 8-pin combo or a pair of 8-pin connectors.

http://hexus.net/media/uploaded/2015/3/35a9438a-f002-446f-ada5-61ccb42aa4be.jpg

Last but by no means least AMD reportedly offered a tantalising glimpse of the performance on offer in some current PC AAA games we already know well. Above you can see a graph comparing the AMD Radeon R9 390X WCE with the R9 290X in PC gaming. These comparative results are from 4K gaming sessions in, from left to right; Battlefield 4, Far Cry 4, Tomb Raider and Alien Isolation. The graph's 'false bottom' axis starts at 0.8 to be more eye catching but 60 per cent performance uplifts are shown, on average, in these four popular games titles.

Edit: just noticed these are 4K comparisons so 60% faster than 290X puts it ~~about same as~~ about 25% faster than TitanX I think. :eek:

Will be a lot cheaper so looking forward to this.

Gerard · 27 Mar 2015 at 21:50

395x2 should be interesting

People said 7990 wouldn't happen as the cores were too hot, same with the 295x2.

Orangey · 27 Mar 2015 at 21:54

Anyone remember Bermuda?

Seems a little high to me for a single GPU solution from AMD.

Would need to beat Titan for that price (would be amazing if true!)

I thought AMD was the nation's choice for bringing fair value/performance?

Really hope they smash it with the 390X, Nvidia's getting too big for my liking.

TonyTurbo78 · 27 Mar 2015 at 23:20

If its a Titan X beater or even a match for it, that's a hell of a lot of performance. Plus you gotta factor in the HBM is brand new tech and will cost more...Everything will be at a premium I expect. If it's going to be a monster card, AMD wont sell it for peanuts, and at £600 to £700, that's still saving £300 over a Titan.

Nutella33 · 27 Mar 2015 at 23:27

Why? If the performance is good why shouldn't they sell it at the price nvidia sell their second tier card (ti)?

When has a company ever released a card that outperforms the tier above its target audience for 40% less money? And then also their pricing would still be judged as "a little high"?

Honestly it just seems people are being delusional through hope or pushing the bar so high that anything realistic they actually produce can be pointed at as a failure?

Beating a Ti at the same price would be a great release. Anything touching within reach of the X for that same price will be magnificent

TonyTurbo78 · 27 Mar 2015 at 23:52

and how much do you think the 980ti will be??

Can you remember what the 780ti launched at? wasn't it about £600, some cheaper than that and some more expensive depending on the brand? I'm guessing the 980ti will be no different, coming in between £600 and £700. Now if the 390X is a better card than the 980ti, its going to be priced in the same bracket to go toe to toe.

rolypolyman · 28 Mar 2015 at 00:31

I certainly wont be buying it at £600-£700 no matter how good it is. I just bought a Panasonic Smart Led Tv for £269 brand new delivered, what a bargain. Seems to me most other technical electronic devices seem to be continually falling in price except for computer parts. I can see me being out of pc gaming within the year unless things turn around.

HEADRAT · 28 Mar 2015 at 08:28

There is a slump in PC sales so they are increasing the prices to make up the shortfall.

Bonjour · 28 Mar 2015 at 08:32

Plus it's a very niche market.

Great deal on the TV btw.

For £600, it should only really have to come within 15% of a Titan X to be deemed 'good value'.

Sorry, my post was in reply to CF's, we posted at the same time.
I agree at 600. That's why I think the 390x will be around that price as it's clearly the competition they are going for.

Devrij · 28 Mar 2015 at 08:45

While I don't disagree that a card with near titan performance could reasonably be priced at about 600 quid, I won't be buying it if it's that much. I just can't justify spending that much. 400 is about as much as I would spend. I got my xfire 290s for that, so a single card is going to have to really impress me to get that kind of money out of me. Might be a while before I see it at that price though!
