Sounds too good to be true to have Fury X performance with 192-224gb/s bandwidth given how GCN is very, very bandwidth hungry but I'll definitely be happy if it is true! However,, given that the rumor said "around Fury X performance" that could mean a lot of things. Tied Fury X at 1080p? 5% slower at 1440p? 10% slower at 4k? Any of those could either be fantastic news or downright disappointing.
Either way, bring on the new GPUs!
It's reminiscent of Zen hype in the other sub-forum -- 8 core Zen with Haswell IPC with 4.2-4.4Ghz boost, and while at it in a 95W TDP and priced under $400. This is how AMD products are set up to fail on this forum. A certain minority will keep hyping something up and when data comes out that shows it may not live up to their expectations, they disregard it and hype up the expectations even more.
Thus far, I have not seen 1, not 1 reliable source, that has been able to produce any evidence to support the claim that Polaris 10 will = Fury X @ 130W TDP.
It's all like statements that someone makes online, the statements themselves aren't verifiable. But then it magically becomes the truth and people go with it.
For example, in AMD's own slides, they claim 2.5X perf/watt compared to 2014 GCN parts. What does that tell me as a reader? Well it 100% means the 2.5X improvement had nothing to do with it over Fiji. And yet, here we are with people going along with a 2560 shader 130W chip ~ 280W Fiji. So this forum magically went from having 390X +5-10% performance in Polaris 10 (280W vs. 130W), to now claiming that nope, it's not good enough. Let's just bump that up to Fury X. And then others on other forums (WCCFtech or Videocardz) even go on as far as to say Polaris 10 is a fail if it cannot easily beat 980Ti/Fury X. It's because people cannot accept that NV's GP104 will smash Polaris 10 into the ground and that AMD is 6 months behind with Vega 11.
I personally will not believe that Polaris 10 with 8Gbps 256-bit memory bus and rumored 230-240mm2 die size will match the Fury X.
Like think about it, on April 26, AMD is launching Radeon Pro Duo with an expensive water cooler for $1500 US, but just 1.5 months later here comes Polaris 10, with 8GB of VRAM, using 1/2 the power and costing way less than a Fury X? So why wouldn't AMD just cancel that Radeon Pro Duo and release a dual-Polaris 10 card without expensive water cooling, more VRAM, better features (HDMI 2.0a, DP1.3, etc.)
Logically, this tells me Polaris 10 is being overhyped everywhere online. It's a staight up midrange product that's now being hyped way way up since it looks like AMD will have nothing to counter 1080. It also contradicts AMD's own strategy of bringing 290/290X spec to more affordable (sub-$349 price levels: AMD's own words, own presentation). So now I am supposed to believe that Polaris 10 will cost less than $349 and be as fast as the Fury X? I am just following along all of this logic.
Sorry, but I don't buy it. AMD's track record speaks for itself -- 290X, Fury X, massive hype and both failed to deliver. I'd rather be cautious than hype up another midrange AMD chip.
Even sites like Videocardz are starting to post pure garbage like Polaris 10 replacing Fury X, the same site that posted AMD's roadmap showing Vega as a Fury X replacement. Facepalm!
