You understand the notion of reference specifications vs AIB/partner board specifications, yes?
yea I get that BUT PR and marketing is not doing their jobs as if that gets out people will know it as 375w vs what the actual use is.
its just not a good idea by far to post it that way
The rebrands are already being sold, so I guess we'll be seeing their reviews as soon as Tuesday.I'm sure it will be covered in the reviews ... any idea when they will be coming out?
8GB of GDDR5 probably uses a bit of power.
As noted, that can mean something else. But "750 Watt Power Supply (Suggestion)" if allowed to stand could actually cost some sales. Even a decent 650 watt psu should be overkill. Hmm, https://www1.sapphiretech.com/productdetial.asp?pid=AC46C7B3-9A55-4270-8875-ED77018A99BE&lang=eng, same "750 Watt" for the psu but only < 300 watts for the card. This 290x card is only clocked 30 MHz slower, 1020 vs. the 1050 of the faster 390x. Both cards with 8GB. No mention of the black diamond choke from the 290x on the 390x page.375w ouch

"Black Diamond Choke
Choke is an important component of the graphics card. By working with the component engineer, Sapphire’s black diamond choke is 10% cooler and offers 25% more power efficiency than a normal choke. The graphics card will be more reliable and save energy."
Interesting if it truly does save that much power in the real world. But ouch if the older boards/cards had some better components. Though we can't rule out that the posted spec's were rushed and are off.
That Black Diamond Choke mumbo jumbo sounds a lot like monster cable copywriting. If there is any truth to it at all, my guess is that it's 10% cooler and 25% more power efficient than other chokes, but that it has very little practical impact on the power consumption of the full GPU.
True, true, and now that I think about it I remember seeing some specification listings flat out just telling you how many amps on the 12v rail your psu should have.Graphics card manufacturers are (understandably) wary of crappy PSUs that cannot sustain their nominal wattage, so they tend to grossly overstate the PSU recommendations for their cards. I can't blame them when you have crappy brands like Advance/LC Power/Heden selling 500W PSUs that fail, catch fire or explode as soon as you try to pull more than 250W out of them.
OEM strings from the latest Catalyst drivers show that Iceland is used in R5 M315, R7 M340, R7 M360. No mention of R9 M370X though.
What I mean is: choke A has a loss of 1%. Choke B has a loss of 0.5%. OMG! Choke B is 50% less power than choke A. That, and what you wrote about temperatures. (For the record: all I know about chokes is what I just read on Wikipedia...)I really, really doubt that. It's more likely that some marketing guy compared two temperature readings in °C and computed percentages from them.
At least 128 bits with GDDR5.
It cannot be anything different.
Is there any evidence of that? It presumably benefits from GCN3's compression tech, and its competitor (Nvidia's GM108) makes do with a 64bit DDR3 interface (in all known implementations).
If so, then I stand corrected and this thingie, which is described in notebookcheck as "a new derivative of the Tonga chip",
comes with 64 bits DDR3 memory. WOW
this old rumor seems to ping on today's reality except for calling Iceland a cape verde replacement.
It is set to replace the Cape Verde HD 7700 series GPU.
So, there will be Antigua XT (Tonga XT) with 2048 shaders in R9 380X?
The first table misses it.
Only by sacrificing profit. I would be surprised if skipping a generation was financially good idea.While the R9 380 does compete well with the GTX 960 ...

Clock changes of 380 show AMD having higher confidence in memory bandwidth efficiency, but they are still 50% behind GM206.
...You can't automatically assume that GM206 has 50% better bandwidth efficiency.
