Hang on there mate, let's look at the original comment shall we..

This guy isn't aware that Nvidia sell an entire range of GPU's from low to high and even enthusiast Titan X.

Now he knows AMD aren't the only option.

The way I look at is this, either he was trolling, suggesting Nvidia only sell $1000 cards, or he genuinely didn't know that Nvidia cater to all budgets.

So I either called him out on his trolling, or educated him so now he knows AMD aren't the only option under $1000.

Just doing my bit :D

You clearly need to get some better glasses, as you missed my response yesterday ;)

The 390x is the card we all believe is there to have a go against the titan? It's the card I personally want, therefore I compare it against the titan, at £1000.

You've also got to bear in mind, that at present, AMD cards show a better performance in DirectX12 which is something I can personally hold on until July for :)
 
Just because the titan x is £850 does not mean amd should over price their 390x.

If it's anything near a titan x performance wise it should still be the cheaper alternative and seen as vfm and will sell well at £499. Any higher and they might shoot themselves in the foot.
 
IF it has anywhere near titan X performance then I would assume it to be quite expensive to make. How could they afford to price it so low(£500). 290X was £450+ wasnt it?

I have no idea how much these things cost to make.

Ha, just read your response. Obviously my posts were meant as a joke, your original post read like Nvidia only make $1000 cards.

I agree the 980 is pricey compared to the 290X, but leading cards are always more pricey, the 970 has some lost appeal after the memory issue.

Price changes everything, at it's current price the 290X is a steal. Just don't get two unless you like being in Sahara types environments. The 290X is best price VS performance card now.

When 3XX series eventually get released, and depending on their performance I would expect a big shake-up in prices on the Nvidia side, with the 980 Ti taking the current 980 price point and the 980 dropping by a fair big chunk. Nvidia can only charge what they like when they have no competition, this will change soon. Hopefully in June.
 
Fiji XT Is 8GB

Some pretty interesting information has surfaced over at Bitsandchips.it, one of the more reliable sources out there. This is one of the first independent confirmation we have about AMD’s flagship GPU shipping with 8GB worth of HBM memory. The report states that the GPU will utilize a dual link interposer to stack 2x 4-HI HBM components for a net total of 8GB HBM.

Fiji XT flagship shipping with 8GB of HBM memory – confirms report

Citing internal sources the publication claims that AMD will be presenting the Radeon R9 390X at Computex in Taipei and that th flagship will be a single GPU card (Fiji XT). It will also have 8GB of memory as rumors and reports have previously indicated. AMD will be employing a technology by SK Hynic called a “Dual Link Interposer” which will allow memory capacities upwards of 4GB without the use of 2nd Generation HBM. When 2nd Generation HBM memory arrives from SK Hynix, the report states AMD will be able to shift seamlessly to the new standard.

The problem arises from the fact that the 1st Generation HBM memory is limited by design to just 4GB worth of capacity. While 2nd Generation memory can support up to 8GB of capacity, its production time line is too far for AMD to be able to use it in its Radeon 300 series designs. And AMD is well aware of the fact that 4GB of memory is no longer enough for a flagship product, therefore the only solution is dual link interposing. With a Dual Link Interposing design, SK Hynix will be able to stack 4x (Dual 1GB HBM modules) via an Interposer (2.5D stacking). The design will have very high performance at low clock speeds and will also be very power efficient as compared to GDDR5.

2x 4-HI HBM1 (which should technically be called 8-Hi-Hi according to nomenclature rules) features a 1024-bit interface, two prefetch operations per IO (dual command) and can push 128GB per second per pin. The tRC is 48nm, tCCD is 2ns (1tCK), and VDD is 1.2V. The 4-Hi HBM2 (generation 2) features a 1024 bit interface, two prefetch operations per IO (dual command), 64 Byte access granularity (=I/O x prefetch) and can push 256 GB per second per pin. The tRC is 48nm, tCCD is 2ns (1tCK), and VDD is 1.2V. If you remember we already received a rumor of Fiji XT shipping with 8GB of HBM memory, however since HBM1 can only support upto 4GB – the general assumption was it would be HBM2. This report clears up that misconception.

Isn't the flagship the 395x2 ?
 
Well that report seems to agree with what we thought thought about HBM1 only supporting 4GB, even though it has been suggested that, that isn't the case. One thing that does seem clear, is that everyone agrees that 4GB isn't enough for a flagship card.
So however AMD put 8GB on the card, doesn't really matter, it is just that they do.
Now release the dam things already.
 
8GB HBM would be ideal, I think 8GB is the sweet spot, enough for all current games and plenty of room for new ones. 12GB on the Titan X is overkill unless your running triple 4K screens, which is a possibility for that type of buyer.

Looking forward to seeing legit benchmarks of the 390X, will likely pick one up at launch to have a play. Hope it beats the Titan X, but on par would be great as well tbh.

Yeah the original article says its the 390.

Then i would take the article with a pinch of salt. Why would AMD go to the trouble making chips which are 390x chips then lasering out cores to make them 390 equivalent then use these chips for the 395x. I would assume it would be more cost efficient and easier to just use the chips intended for 390x and then use these for the 395x would make the 395 cheaper to make and provide it with more performance.

This is what they did with the 295x.
