Thanks so much for this graph. I always thought the correlation between temps and power consumption was pretty low, but this confirms it for me. Looks like a little less than 1 watt per 3 degrees Celsius. Need good water cooling to bring about a significant (15+ watts) power savings at same clock speeds and voltage.

Face2Face beat me to it -- You are being too conservative because you aren't accounting for the differences in power usage between the GPU and CPU.

3 data points on the 295X2 AIO:

TPU got R9 295X2 to run at 61*C max overclocked. In FurMark their card only reached 68*C!

AT has it at 73C

Hardware Canucks has it at 63.3*C

That 2600K overclocked uses way less power than an R9 390X would use. That means 20-25W reduction in power usage from 94-95C AMD reference blower to mid-60s/low 70s is probably a done deal.

Don't forget that when you overclock the Titan X on reference blower, it becomes a loud card. A lot of gamers ripped apart R9 290X reference blower, but the Titan X OC is up there. Essentially a water-block is required to have a quiet overclocked Titan X. AMD is bringing that right out of the box? Sounds like a great idea to me.

By going WCE edition with a reference card, AMD accomplishes all of these:

1) Likely a miniITX PCB, or at least one significantly smaller than the Titan X
2) Reduction in noise levels, temperatures and power usage via AIO CLC
3) Reviewers will not be able to talk smack about how hot and loud the reference blower card is, blatantly ignoring ALL after-market options as was the case with HD7970/7970Ghz/R9 290X. By releasing one of the coolest and quietest reference designs right off the bat, AMD is doing R9 295X2 all over again.

It's going to be interesting to see if smaller PCB+warrantied AIO CLC is the future of flagship GPUs since it means AMD/NV can make 300-350W GPUs easily with an AIO CLC keeping them cool and quiet.

Most importantly, because the HBM1 and the GPU are likely cooled together, the entire card runs cooler and AIO CLC is extremely effective for high wattage overclocking.

Max overclocked and overvolted Hawaii XT easily uses 350W of power but under a 120 AIO CLC is runs quietly at 80C. No reference blower in the world can cope with this. It's going to be very difficult to find an air cooled blower than can cool a 350W card like this. You basically need a 2.5-3 slot Sapphire Vapor-X or MSI Lightning style cooler to match this.

May 8, 2015 - WCCFTech "It's an official render that AMD showed us.". I guess no one believed them because it was WCCFtech.

AMD seems to be going full "next generation" on this one - AIO CLC, no DVI, miniITX PCB. No DVI means the monitor makers should finally start taking DisplayPort a lot more seriously! I hope NV follows the same path with Pascal and gives us the option of no DVI, and AIO CLC. Finally a bold new direction in 250W+ GPU design and the long overdue to move ditch the old style I/Os that don't support FreeSync/GSync. At the same time this gives AIBs a lot more room for differentiation - they can make different sized PCBs, go air cooling, add back DVI.

Since HBM1, interposer and the GPU are now 1 cohesive unit, AMD will have full control over the manufacturing of all 3 of these components. That means the 'core' aspects of the videocard will be consistent across all AIBs. Hopefully no more cheap designed cards (XFX ahem HD7000 series, Sapphire HD7870 transistor issues), or AIBs skimping on VRAM and substituting Hynix for Elpida. Now, there will be more consistency.

It's watter cooled but why does it then still have this air-grill on the second slot usually for the blower to blow out air? that would just be a great inlet for dust...why not cover it?

Hopefully the AIB vendors still allow DVI on their models, plenty of monitors still ship with DVI cables included.

My 8-year-old (!) Westinghouse has an HDMI port as well. With TrueAudio/HTPC use where you need to send Audio+Video and FreeSync/GSync requiring DisplayPort, DVI is outdated. It just obstructed the top part of the exhaust bracket. If more modern monitors have DisplayPorts 1.2 (then 1.3) and HDMI 2.0, DVI will be dead completely. And it should be as it's outdated tech. If NV follows through too, monitor manufacturers would have no choice but to focus on newer I/O technologies.

Since it's going to be impossible for any AIB to make an air cooled card on a PCB the size of a 390X that's as cool and quiet, having DVI on their products could be the differentiator they need.

I would like to see a review that compared 1393mhz GTX980 Hybrid against R9 390X and 980Ti.

Dual bios switch?

or some kind of a port?

Damn, that's a short card....And I am all for CLC, I had liquid cooled GPUs before that didn't make a sound above the regular fans and now I have jet engines.
 
the switch when activated cancels out any Nvidia card within a 10 block radius.

Need a new mistress so a red one seems like my thing.
 
I wonder what implications HBM will have for reliability of the card (failure rate). Since the interposer should be more reliable than the PCB and traces that used to connect the GPU to VRAM. how overclocking memory would work. Maybe a small memory OC would result in massive bandwidth gain.

Still not sold on the liquid cooled aspect of the card. I hope it's actually just so efficient that it only needs that tiny cooler haha!

A sensible point made by someone interviewed who had handled the card is that because it's so small you couldn't reasonably slap a large air cooler on it like we see on the current top end cards. You'd have over half the cooler extending down off the end of the PCB.

With water cooling you don't need all that surface area to dissipate the heat and can use a very small block that covers the VRMs, memory and GPU die. I think the card looks awesome in that shot.

It's about time all flagship GPUs shipped with AIO water cooling. They're irritatingly noisy pieces of hardware with reference blowers. The Titan X sounds like a jet airplane once it's under a heavy gaming load. Water cooling makes GPUs completely silent. If you want to put out a 'luxury' GPU, it should be dead quiet, not just using a swanky black shroud and emitting tons of noise.

I couldn't care less about aio complainers unless you paid me to. Aio cooling is great for the high end. Don't have a case that supports it? Buy a new case.... Seriously if you're spending enough money to buy 2 flagship cards but cry because it won't work with your case but you won't spend an additional 80-100 to fix the issue then high end gpus aren't for you.
I can't wait for the launch review. It'll be this or the 980 ti by the looks of things. Going to try to only pay rent and basic necessities until the 390x comes out then decide from there. Ugh, between a new graphics card, 4k TV, and tablet, along with the server I want to build. Too many options and not enough cash!

Because I totally want two of these cards right off the bat (I don't) and I seriously should dump the case I have already and INCREASE the cost of my new videocard by $100 or more? No. I'll buy a 980ti instead.

Or you could buy one with air cooling. There is probably going to be a lot of options from their partners.

Acoustically 980ti will be just like Titan X though; loud!. This is a 600mm+ die that gives off lots of heat. Before I put my cards under water they were getting up to 85C and sounded like a plane. Awful.

This is no different than the transition we've seen over the past few years of enthusiasts who don't do full water cooling getting AIO coolers for their CPUs. Once they get the improved cooling and silence they don't go back. In the case of GPUs it's even better because unlike CPU AIOs when you put an AIO on a GPU, the temperatures are lower than the best air cooling solutions.

You can put a big tower air cooler on your CPU and get great low noise/temperatures because there is room for it. A GPU because of how it's situated in your case can't do the same and you need water cooling or the use of a dual fan open air cooler, not a good option for SLI or for your case internals, to have a quiet experience.

If you're going to spend $1600 on 2 980 Ti's claiming a $100 case is too much is absurd

Not really, AIOs are loud as hell. Yes they are quieter under load but unless you game 24/7 I prefer reference cards. I've had both a R9 295X2 and had my Titan Xs under 980 Hybrid CLCs and both are way louder than reference Titan X at idle. And I'm idling most of the time surfing or watching YouTube. The water pumps in these things are louder than the rest of my computer combined. That's why I dumped water cooling on my Titan Xs and just DIYed a fan solution in the side of my case that lowers temps as allow me to run a silent fan profile on the Titan X cards even during gaming.
