NVIDIA GeForce GTX 1080 to arrive in liquid cooled version at 2.5GHz
WHOA: The GeForce GTX 1080 will reportedly see models with its GPU clocked at an *INSANE* 2.5GHz (NASDAQ:NVDA, TPE:2357, TPE:2376, TPE:2377)
There will reportedly be four versions of the GeForce GTX 1080: the Founder's Edition (reference edition), the normal AIB card (air cooled), the custom AIB card (air cooled) and then the custom AIB cards (watercooled). ZOTAC, Colorful, ASUS, MSI, GIGABYTE and countless others will have some super-powered GTX 1080 video cards to show off, with the rumor that GIGABYTE's upcoming Xtreme Gaming GTX 1080 should reach 2.4GHz on the GPU, all in air - and if that's true, get ready to have your mind blown.
The tease of a liquid cooled GeForce GTX 1080 with its GPU clocked at 2.5GHz should be enough for anyone to be impressed, as it'll allow for 4K 60FPS gaming without a problem. We should expect a few AIB partners to have some insane designs, shown off at Computex 2016 in two weeks time.
This applies to x86 as well. There's a sweet point when Δclock speed = Δpower consumption in any manufacturing node (higher leakage = steeper curve). A desktop cpu may pass that point (turboboost) to maximise IPC. But throughput oriented designs (xeon phi and GPUs), in any given thermal limit, core count is more favourable than clock speed (until you get poor yield)
