Some claiming AMD used them and charged them $650 for water cooling chip setup with high leakage (that cant really overclock far) while keeping the better chip that can easily reach same fury X clock rate with mere adjustment at CCC on simple air cooling (aka the Nano).
*
Higher leakage is usually better at overclocking because they tend to be more stable with extra volt and with WC keeping the leakage, it will overclock much better than lower leakage chip.
The Fury-X still lack proper voltage control and the VRM temp is somewhat worrying with extra voltage.

nano is a fail launch.Go see Overclock.UK which did not sell yet 1 nano and overclock.Uk is the biggest UK retailer for GPUs.
*
It's a product that cater to a niche audience with specific form factor and use-case scenario. How many people own 970 mini anyway?


Overall the Nano impressed me apart from the steep price. I was expecting 390-ish performance with thermal throttle everywhere.

So there's no thermal throttle on Nano? I saw in one video posted above stating that the card is running cool under 75C all the time, that is seriously impressive.
*
No, 75c is the Nano temperature target and 85c is the thermal limit iinm.

Anyone tried the new dota 2 engine?

My R9 290 can't maintain 120fps, GPU usage around 30%+, CPU slightly below 60%. All settings maxed 1080p

While in my cheap laptop with GT 610M, lowest settings at 768p and game render 100%. The fps on average 80+, while on source 1 engine it is only 30fps

It's harder to run on max settings while it is friendly to old pcs
*
120FPS min or average? Mine can't maintain over 120FPS when there's alot of effect on the screen.

Its the frame cap. I didn't unlock the cap because having 120fps coincide nicely with my 60hz monitor. It's like vsync without the vsync latency. Works well with source 1 dota2. But source 2 dota2 can't maintain 120fps. Maybe need to lower settings zzzz. Not like my card is low end
*
Oh, i increased the cap to 200 since i didn't notice any tearing.
Just tried latest client and i got average 130-ish FPS give or take with some rare split secs dip to mid 100s/high 90s. Last week client perform slightly better though with rare dips into mid 110s.
DX11 mode perform lower for me btw.

QUOTE(faidz85 @ Sep 11 2015, 04:52 PM)
For Source 2 will have support for DX12 right? Let's see what they bring to us then.
*
Yes and Vulkan.

QUOTE(JohnLai @ Sep 11 2015, 05:18 PM)
The problem is......it isn't overclocking reasonably well enough.
There was one overclocker who able to overclock (volt modding?) Fury (cut down of Fury X) to 1400mhz and the cooling and power requirements are insane.  shocking.gif
Fiji chip efficiency is thrown out of whack once it reaches 1ghz.  ohmy.gif

I wonder how well will this better binned Fiji/Nano will fare if it is using water cooling. (The lower power phases might be an issue though)

Eh, I am starting to think the other reason that AMD reorganizes the Radeon division might be easier entity separation (sold off? spun off?) if thing suddenly get bad for AMD.
*
What is this "reasonable overclock" for Fury-X according to you? hmm.gif

Any high end card that need volt mod will use insane power consumption. Heck, an unlocked GTX780 with all safety bells and whistles removed can consumed 400w ALONE when overclocked.

Yes the board power limit will be an issue to overclock a Nano over the top especially since board partner not allowed to create custom PCB for it.

That is one of the possibility in case AMD CPU division going under if Zen fail.

Something like Intel CPU or Nvidia Maxwell V2 level of overclocking.

Example, increasing GTX980 base clock from 1126MHz to 1377MHz (251Mhz differences, unless if you consider max boost clock) only resulted in extra 47-67 watts (based on anandtech gtx 980 review)
*
You can't compare clock/clock from different architecture. A 390 at 1.15ghz-1.18ghz is on par with 970 at 1.45ghz-1.5ghz.

Maxwell efficiency came from better much load adjustment especially when gaming where there's is always some idle task/queue in the pipelines.
Load that with an intensive GPGPU compute task, the 980 become power hogger just like Hawaii.

the thing is, would the price fall out the same as they intended when it reach msia?.

Since you can get 390 for just over RM1.3k, hopefully this card will be under RM1.1k. The card probably slightly faster than the R9-280x depend on the stock speed.

Yes, that's how they extracted more performance on the PS4 and XB1 with those low-ish end GPUs.

Does async compute work in old r9 270?
*
Yes, all GCN 1.0 cards have 2 Asynchronous Compute Engine(ACE) including one in Xbox One and PS4(apparently PS4 got 8 ACEs like GCN1.1 and over). each engine can queue 8 task with a total of 16 tasks.
GCN 1.1 and GCN 1.2 have 8 ACE with a total of 64 tasks in parallel.

You can see how dev SuckerPunch used Async Compute in PS4 exclusive Infamous 2nd Son which look really great imo

Yes, since the iGPU is GCN 1.1 so it have 8 ACE but the problem with iGPU is memory bandwidth.

IT HAS 8  thumbup.gif , yeah its using the system ram i use 2400mhz ram can see tons of improvement but mainly on 720p, 1080p need to drop image quality including AA, better off using a discrete GPU, btw thats my steam machine for the living room  tongue.gif . worst case i can just stream my gaming rig to the living room
*
But dev probably won't utilize that much since Maxwell2 can only do 32 compute tasks for parity.
I wonder when AMD will drop HBM for their APU.

Aync Compute in Fable Legends is optimized for XboxOne which only have 2 ACE.

QUOTE
This feature was implemented by Lionhead Studios. We integrated it and indend to make use of it as a tool to optimize the XboxOne rendering.

As more more APIs expose the hardware feature we would like make the system more cross platform. Features that make use use AsyncCompute you always be able to run without (console variable / define) to run on other platforms and easier debugging and profiling. AsyncCompute should be used with caution as it can cause more unpredicatble performance and requires more coding effort for synchromization.

Mostly MSI 390x from comments around the web.
I suggest you to wait for another 1 year before you start playing GTA V again. laugh.gif

That driver only 1 day old, he probably still using 15.7 or 15.8.

VRAM leaked in Catalyst 15.9. Expect a hotfix very soon.
Anyway if this happened, just kill/restart Desktop Window Manager (dwm.exe) to purge it.

AMD Has Held Stalled Investment Talks With Silver Lake

Advanced Micro Devices Inc., a struggling competitor to Intel Corp., was in talks to sell about a 25 percent stake to private-equity firm Silver Lake Management before the negotiations stalled, people with knowledge of the matter said.
The two sides, which met over the summer, have put the discussions on hold after failing to agree on a price and strategy, said one of the people, who asked not to be identified because the information is private. AMD is also considering other strategic options, another person said.
