If they relieve the memory bandwidth constraints and allow GeForce to be somewhat less power efficient = higher voltages and clocks than Tesla, then we're looking at ~35% more performance than a GTX 680. Considering that HD8970 is supposed to be less than 20% faster than HD7970, it seems that NV is about to reclaim the single-GPU crown.
He is incorrect one a major point, the reason for the fused part and low clocks = to fit the 225W TDP. Because these K20s are going to be used as a upgrade, replacing Fermi, which was also a 225W TDP HPC part. Massive sever upgrades would not risk replacing the infrastructure, especially the water cooling units and aircond for the facility. TDP being the same is critical.
Charlie's scenario is only one possibility. Another is they fused them off purely for power usage, nothing at all to do with yields. The clocks being so low would also point to that.
Wishful thinking. I thought the two of you would know better.
Enabling all of the SMXes while lowering the clock rate and voltage further to compensate would allow for better power consumption at the same performance level, that's basic mathematics. Yields are the only possible reason for disabling SMXes. Given the size of GK110 this isn't at all surprising, and may have been expected by Nvidia from the onset. Expect a fully functional part six months to a year after big Kepler officially launches.
Charlie is "usually" right when he is quoting his own sources.
Why do people read that sensationalist site again?
It's good entertainment!
I'm pretty sure reading into Charlie's previous sources, he has friends at MSI and ASUS.. other AIBs im not certain.
It's pretty clear he has no source inside NV itself. But then again, NV is really leak-free.
I really do hope GK110 for consumers will be a high TDP high perf part, none of this crippled rubbish to fit a certain power envelope.. $600 GPU who cares?!
