Powerful enough to threaten the HD 6990?
As a consumer, I love this back and forth between major corporations as they come up with better products every year, and with competitive pricing, trying to win our money. Two weeks ago AMD launched their fastest graphics card yet, the HD 6990. Today I’ll be looking at what Nvidia has brought to the battlefield, the GTX 590.
The principle behind these ultra-high-end cards is simple: a single card isn’t powerful enough, so shove in two GPUs on one PCB. And then people can go further down the rabbit hole if they put it in SLI configuration. But that’s an observation for some other time. Right now let’s see what two GF 110 GPUs look like on one PCB.
Surprisingly the GTX 590 is hardly longer than the GTX 580, and ever so slightly slimmer than the latter too. The cooling fan, as you can see, sits smack in the middle of the two GPUs, both of which are being cooled by a copper based vapor chamber. And then there’s a 10-phase power controller which distributes power to the two GPUs and another two phase controllers distributing power to the 3GB of DDR5 memory modules. The build quality of the GTX 590 seems to be top notch, continuing with the 12-layer PCB with 2oz of copper; something I have seen in very high-end motherboards and exceptionally customized graphics cards.
