Low profile RX460??
Woo, Aria owners clubOriginally Posted by jigger
CAT - I spotted the MSI at overclockers - it requires 6pin power but given the ~ 90W max draw most places seem to see from the RX 460 I suspect that using a molex - PCIe adapter would actually be OK for these cards. The HIS and MSI are both bus powered by the look of it, which would be a shade better. Given the very low temps everyone seems to see a bus-powered single slot card should be dead easy to engineer.
Fingers crossed on the low profile version though - it's screaming out for it and would make foir an excellent LAN party rig
EDIT:
just had a read through that reddit thread and several people pointed out that the workstation card is both low profile and single slot (although I suspect that is lower clocked at default - workstation cards tend to be). Bakc in the day I'd've been crying out for a low profile version of this, but I gave my AOpen rig to a mate a few years back! Still, it's clearly possible - come on AMD partners, get on with it!

The HIS card has a power connector,and that MSI low profile card has a different product description too.Woo, Aria owners club

Ah yes, I meant the HIS in fact. It's tempting to point him in that direction since he'll get the best performance out of it for the money, and I'm pretty confident the PSU will take it (although I'll have to check back to see what's actually in there - might be a 250W one...?). OTOH I oculd suggest he picks up the bus-powered Powercolor and undervolts it, which should help it maintain its boost clock. Or he could up the power target and trust the motherboard to cope...
The WX4100 has a base clockspeed of 975MHZ but has 14% more shaders than the RX460.
why buy this at £130 when £50 more will get you an RX 480?

Maybe because you don't have £50 more? Or maybe because that card has been pre-order since 29th June and still hasn't turned up? Or maybe because you're not confident about running a 150W+ card on your PSU?
All sorts of reasons. Plus at £130 it's one of the more expensive RX 460s, anyway; a better question would be why you'd buy that rather than a 2GB one at £100...
I suspect that's how they'll do the mobile cards as well - fully enabled but running at lower clocks/voltages. A fully enabled card @ 975MHz would give you 90% of the performance. Take that down to 900MHz and you get 85% of the desktop RX 460 performance, but I suspect power will drop down dramatically.
In fact, it'd be interesting to see what the desktop card can do if you reduce the power target...

Remember,the RX460 runs at 1090MHZ to 1200MHZ,so 1024 shaders at 975MHZ would place performance between the two boost states of the RX460. It kind of looks like the R9 M480 is around the same performance as a desktop reference RX460 looking at those leaks and ahead of a GTX970M which is a GM204 based chip.
Edit!!
Saw this posted on another forum:

The bottom curve is for Polaris 10.
Yeah, my % were compared to a desktop card that could actually maintain 1200MHz - the bus powered ones don't seem to be able to under stock power targets though. The voltage graph doesn't surprise me and confirms what I think we all suspected - the desktop cards are running on the hard edge of what can be acheived on 14nm in terms of clockspeed. Given that power consumption varies with voltage squared, sticking to < 1000MHz so you can keep the voltages at the bottom of that curve is going to save huge amounts of power. Polaris on GloFo 14nm is *totally* a mobile/power optimised GPU.
An RX 460 paired with a gen 7 APU would make a interesting notebook. IIRC the new APU's are rated at around 12 watts or something silly like that.
IIRC it's proportional to F*V^2, so for that curve the 1200 -> 1000 MHz drop is about equal to the 1.04 -> 0.96 V drop (20% Vs 17%). That all comes to a 1GHZ chip taking about ~75% of a 1.2GHz chip, so you'd go 75W -> 56W
The TR review with framepacing:
http://techreport.com/review/30488/a...-card-reviewed
Even against a bus powered GTX950,the RX460 with another power connector draws similar power.
Having said that a fully enabled chip in a smaller form factor might have been better PR for AMD IMHO,since the GTX750TI draws less power still.
The current RX460 cards look rather large and from what I have seen from personal experience the GTX750TI was quite popular for people upgrading prebuilt PCs due to its small form factor and many bus powered versions.
So I would really want to see how bus powered RX460 and bus powered GTX750TI and GTX950 fare in comparison.
I wonder if we will ever see a WX4100 compared against a bus powered RX460?? I wonder if it would be possible to get gaming drivers to work on it.
It does make me wonder how the GP107 will do though...

It looks like the desktop and mobile RX460 cards have similar performance:

I'm surprised I haven't seen mention on the forum of David Kantar's recent video: http://www.realworldtech.com/tile-ba...n-nvidia-gpus/
(written up version http://www.anandtech.com/show/10536/...ation-analysis)
which ties in with Nvidia's merging of Tegra and desktop technology and explains the power usage difference that this usually mobile technology would allow.
It may also give possible explanations of Nvidia's lack of boost from Vulkan/DX12 games, though Vulkan supports tile based rendering should Nvidia want to expose that.
He was comparing a Maxwell card to an old Terascale based HD6670 though.
