No, it doesn't. The reason this is the case is because the 980ti doesn't make use of all its memory address space. If nvidia put 12Gb on this card, then yes, it would have the same problem, i.e. 10.5 GB out of 12GB.
Well, no it wouldn't.
IF the cut GM200-310 had disabled ROPs and their attendant 32kB L2 cache per ROP while maintaining the attendant memory controller it would have the issue. The GM200-310 in the 980 Ti retains the full 96 ROPs and 3MB of L2, so it doesn't.
I'd swear that the number of people who are unaware of the actual facts actually grows as the correct information
becomes more widely disseminated - it's like stepping into BizarroPowerUp by mistake, or a guerrilla marketers training ground.
This thing is the usual Nvidia's slap in the face to Titan owners, history repeats itself.
How many - in your estimation - prospective Titan X buyers would have been unaware that Nvidia would launch a reduced cost 980 Ti in short order - and very likely in the same time frame as AMD's launch - at a much reduced cost?
I don't know of many people who would spend $1K on an individual hardware component that aren't in some way attuned to - at least, the consumer side of the industry.
For those that are willing to spunk $1K on a card without investigating the options, industry forecasts, a general consensus of forum posters, and historical fact?....Maybe you're familiar with the saying " There ain't no cure for stupid"
