Pot calling the kettle?

I hate to tell you but the PS4 is already choking on the 176GB/s bandwidth available. If you think that a 30% faster CPU and a 220% more powerful GPU can be satisfied with 218GB/s, you are seriously wrong. leaving aside wherever that weird bandwidth comes from, it doesn't exist in any gddr5 data sheet. And while we are on the subject, if you do more gpgpu work as you imply (which is correct if developers actually used it), you also grab/send more memory down memory lane. So you not only have a higher CPU and much higher Graphics Compute load on the memory bus, you would also have an additional GPGPU load tacked on it, in the end three "customers" are fighting for the one memory bus. There is an advantage having a common memory pool for everyone, but there is also a serious disadvantage - when too many processors fight for it. 

I was editiing my comment but did not save it.   I purchase products and services based on my own, internal replacement cost not what the market dictates.  Any future iteration (that is better and cheaper) is factored into my decision because these type decisons tend to be on the impulse side of buying...and I would venture that its the same for multiple people.  I can choose to keep what I have that is fully functional and working or buy the new one, its as simple as that.

For the matter at hand, the videogame marketplace is big enough for the disgrunted people to leave and have those intereted in buying a PS4/K to replace them.

couple of things I'm wondering about: Is PS4OG being phased out like PSphat? That userbase should be the majority for a long (if not entire) time.

Also, PS4Only owners, are you more likely to upgrade to Neo, or diversify (buying any Xbone version, NX, etc)

Anyway, I have to salute Sony here, staying aggressive and modern despite already having the most powerful console + 1st place by landslide. I imagine this started out as a slim with 4k streaming/scaling update, but then added power to complement their VR.

How would you know ? Out of all the GCN GPUs, the PS4 has one of the highest BW/ALU ratio in recent time ... 

Delta colour compression exists to also help reduce memory bandwidth traffic too ...

I think some people here have no experience with PC gaming. PS4 NEO is like buying a faster graphics card for your PC and slightly overclocking your cpu and memory. Only instead of having to find the best graphics settings yourself the developer will do it for you. Sounds ideal to me.

Some people here have experience with console video game development. Console games are not at all made in the same way as PC games, and doing things like this throws a monkey wrench into pretty much everything.

Worse case scenario you will have only minor benefit with the PS4 NEO, so what's the problem?

Well, there is only one thing to know: in real life, you won't get this bandwidth. Eurogamer had an article about AF on consoles and the article said that when CPU and GPU have access on memory, the bandwidth is way less.

As a developer you're faced with two choiced, increased development costs with no anticipation of greater sales, or maintaining current development costs and splitting resources that would be spent fully developing the PS4 game now working on making the PS4K enhancements.

So you either have a more expensive, less profitable game, or a poorer quality game than you would have if you just had to focus on making a PS4 game.

So why would I be excited about this if i was a third party developer? Sony just made my job more difficult for no reason.

I know the GPU will never get the theoretical limit when considering memory accesses from the CPU but what I'm asking is how does drkohler know that memory bandwidth is bottleneck ?
