ThePCEnthusiast.com: "Looks like the next generation dual Hawaii graphics card isn’t going to be called R9 290X2. At CeBIT, it has been reported that AMD revealed to a limited number of people (and behind closed doors) a dual Hawaii graphics card – the AMD Radeon R9 295X2 codenamed Vesuvius. The revelation happened after AMD sent out “top secret” messages to tech reviewers containing a photo of their faces in mirrored effect. There’s also a note saying that two is better than one. Well that was pretty obvious."
ThePCEnthusiast.com: "Finally, the much anticipated Dual Hawaii graphics card – the AMD Radeon R9 295X2 was recently revealed thanks to a Chinese community site Chiphell. Most probably reviewers already got the steel briefcase which enclosed the R9 295X2, that’s why we are now seeing pictures of the actual card itself. The AMD Radeon R9 295X2 Dual Hawaii graphics card, codenamed “Vesuvius”, sports an air + hybrid water cooler to cool this long graphics card. There are two GPU water blocks, to cool the two 28nm 250W Hawaii GPUs, which are connected to a 120mm radiator. The 90mm fan located on the middle of the card cools the heatsink that absorbs heat from the memory, VRM and other components of the card."
Maximum PC: It's good practice to take Internet rumors with a healthy dose of skepticism, especially on April Fool's Day. Got it? Good, now we can continue with what are claimed to be the first photos of AMD's rumored Radeon R9 295 X2, a dual-GPU graphics card that some have surmised could carry a massive 500W TDP. If that's true, a gnarly cooling solution would be mandatory, and certainly that's what these early photos show.
ThePCEnthusiast.com: "AMD is will be releasing the much anticipated AMD Radeon R9 295 X2 Vesuvius Dual Hawaii graphics card on April 8, 2014. That’s just more than a week from now. The codename R9 295 X2 isn’t really a confirmed name, before it was R9 290X X2. But more or less you get the idea. AMD’s #2betterthan1 campaign has been around for quite some time now. NVIDIA has already announced their GTX Titan Z Dual GPU graphics card. Perhaps AMD had already anticipated NVIDIA’s move and decided to unleash the “Vesuvius” after NVIDIA has made their move."
A single 290X runs hot, I imagine a dual 290X could heat your home as well with the appropriate ducting.
AMD seemed to have struggled to compete with Intel for CPU's and nVidia with GPU's and just gone crazy boosting clock speeds which take more power and therefore generate more heat. I've used AMD for years as they always give good bang for buck but for my upgrade this time I've gone back to Intel and nVidia
