Huh? It's paging 4GB to system ram. The Titan is 30% faster.
Why do you think that has to do with the memory being HBM rather than AMD focusing on memory management?
And yet the fury can't play Doom at nightmare settings. This is all a pointless debate. The fury is one of the worst high end cards AMD has launched in a long time, just move on.
Because the huge amount of bandwidth from HBM allows for that memory management...

And any performance benchmarks for that?Steam Launch Option "+menu_advanced_AllowAllSettings 1" unlocks Nightmare mode
just look at l2/1/3 cache, slower = larger size , faster = smaller size.
that's why faster HBM can make up for smaller vram. but guess it's too difficult to grasp because it's the amd who is doing it ? and you green fans feel ashamed for some stupid reason ? lol
This whole post is completely wrong.
You're free to spell out why instead of providing a fact-free oneliner.

What Bacon1 and kraatus77 are saying is that if a GPU needs a certain bandwidth to function at full speed and which is less than the available bandwidth, you can use the excess bandwidth to allow for VGA memory access to main memory without interrupting the GPU > VGA memory transfer.
Is it possible to do a burst transfer from VGA memory to an on-die cache that reduces the needed memory access time when compared to a slower memory?
Yes, this is true, but what I'm saying is that a very high bandwidth memory moves the point at which this happens. You can, to some degree make allowances for memory size by having excess bandwidth. Eventually you will saturate the new mechanisms, but this will always happen for all cards, no matter the memory.This is completely wrong. GPU to system RAM transfers are limited by the PCIe bus, which allows 16GB/s of bidirectional transfer with PCIe 3.0. Doesn't matter how fast the VRAM is, it's going to run into this bottleneck once it pages to system RAM. Even worse is the latency however.
This is why VRAM capacity matters, because the more VRAM you have, the less trips the GPU has to make to system memory. A well tuned 3D engine and the OS will balance texture swapping between VRAM, RAM and storage so that the latency penalty is hidden.. But if the VRAM limit is constantly being exceeded, then there is nothing that can rectify it other than getting more VRAM.
