Rumor are suggesting that R9 390X is just 20% faster GTX 980 than let alone GTX Titan X.
One rumor.
Rumor are suggesting that R9 390X is just 20% faster GTX 980 than let alone GTX Titan X.
R9 285 1080p and 2160p index beats the R9 280X :

As much as I'd like to see AMD do well with something they release, what you said is not true at all. In June it will be what? 9-10 months since the 980 came out. If by that time they only manage a 20% improvement, no matter the price, I call it a failure.
So the range is pretty wild out there in rumor-land. Anything from 20% above 980 to 50% and demolishing Titan X. It's fun to speculate and that's about all it should be.
I don't think so. Titan X is nearly 50% faster than an R9 290X and has 20%+ overclocking headroom. For R9 390X to "demolish" a Titan X, it would need to be 20-25% faster. To me 5-10% faster is not demolishing.
There's developers & journalist who claim the leaks prior of 50% faster than R290X is a lowball figure and that its a "lot faster".
So as I said, lots of figures being thrown around.

That means if R9 390X is 65% faster than an R9 290X it's barely 10% faster than a stock Titan X. Honestly, not sure how we got to this point but a lot of people on this forum seems to just keep ignoring price altogether since 980 came out. Sure, Titan X overclocked brings awesome performance, but at $1K price, who cares for 99% of the market. If we get consumer GM200 6GB/390 non-X/390X with 87-90% of Titan X's performance at $499-600, the Titan X is all but irrelevant for 99% of gamers like the original Titan became less than 9 months from its launch once R9 290/290X launched.
Alternatively, if I had to choose between SLI/CF for $1100 that offered me 87-90% of Titan X's performance when CF/SLI doesn't work, but 50-60% more performance when SLI/CF works, I'd take the dual card setup all day, every day. Since many gamers are not loaded, for A LOT of people "demolishing" the Titan means owning it in price/performance by miles, rather than outright beating in in performance. Would you say R9 290 at $399 demolished a $650 GTX780 in performance? No, but as a buying choice, it certainly did for brand agnostic PC gamers. Literally overnight a $650 780 became irrelevant. R9 390 nonX/X will not demolish a Titan X in performance, but it's almost a guarantee that they will supersede Titan X as the smarter buying choices (and of course can't discount consumer GM200 6GB cards).
Titan-X is 45-48% faster than R9 290X. If R9 390X is on avg 55% faster than R9 290X that would mean the R9 390 is fighting the Titan-X and at a price closer to USD 700. How is that not owning in price / perf ?
R9 390X - 4096 sp, 4 shader engines (4 x 1024 = 4096 sp), 4 tesselation engines, 4 raster engines, 8 GB HBM, 64 or 128 ROPs, designed for 4k gaming. 1/8 rate double precision for Radeon and 1/2 rate double precision performance for flagship Firepro. 500 - 550 sq mm die. TDP 260W.
USD 800 . 5 - 10% faster than Titan-X
R9 380X - 3072 sp, 4 shader engines (4 x 768 = 3072 sp), 4 tesselation engines, 4 raster engines , 4 GB HBM, 64 ROPs, cost and gaming performance optimized die. 1/16 double precision performance. 350 - 380 sq mm die. TDP 200w
USD 400. 10 - 15% faster than GTX 980
The thing about the chart that was posted along with R9 390X specifications
The words below the chart are blurred, but you can easily make them out to be saying 'based on performance estimates'. So it seems a way off.

If 390X is 4096SP - 128ROPs it will certainly destroy Titan.
That is R7 265 x 4, it will match it @ 800-850Mhz. D:
I don't know where you come up with that.
The Titan X has exactly 50% more SP's than the 980, those 4096 SP is slightly less than 50% more SP than the 290x. The Titan X also has 50% more ROPs than the 980, while the 390x has slightly less than 50% more than the 290x. Based on that, I'd expect to have a similar increase over the 290x as the Titan X has over the 980. The one area the 390x may show a larger increase in spec's is the clocks.

Worst case scenario:380/380x are rebrand 290/290x
390x-underperforms and only 20% above GTX980 in 1080/1440P on par with TITANX in 4K
390- 5% above GTX980 in 1080/1440 and 15-20% faster in 4K
380x-rebrand 290x.Same/worse performance than GTX970
380-rebrand 290.Same performance as 290

Which would make the +20% above GTX 980 which VR-Zone presented legit.
I don't think this is going to happen because R9 290X is faster than a 970.

In your assumptions you didn't account for a single improvement in GCN architecture (Tonga has 40% more efficient colour fill-rate/memory bandwidth and superior tessellation/geometry performance to R9 290X). Therefore, it's not as simple as just applying a 45% increase to R9 390X based on 4096 SPs/256TMUs.
The Titan X is 45-48% faster than a 290X depending on the review. Based on paper specs alone (1.05Ghz 4096 SP/256 TMU part), the R9 390X has a 53% greater theoretical performance, not accounting for a single improvement in GCN 1.2/1.3 vs. 1.1.
many consumers cannot play certain aaa titles with even 4 gb of vram no matter how much system ram is available, or how fast it is.
It's not like the Titan X has a 50% higher performance than the 980. They never scale perfectly like that.
The point stands though, based on the stats he gave, it probably won't destroy the Titan X. It'll likely see a similar improvement.
He just showed you with actual data that shows GCN scales very well with increased shaders, rops, tmus. Almost perfect.
There's reasons to think with HBM's lower latency, they could also improve IPC/SP on top of any other architectural tweaks.
At this junction, you either are a pessimist (20% above 980), realistic (50% above R290X) or optimistic (much greater than 50% above R290X). There's leaks to support any stance.
