The PS4 is a great console, It has a CPU with 8 little cores that achieves a Core I3 like multithreading performance, a nice 18 core shader graphic card derived from Radeon HD 7870-7850 that gives 1,84 Tflops and 8 GB of DDR5 with 176 GB/s of Bandwith. With these specifications it can run almost every game at 1080p 30 FPS. It could have been a little more powerfull, but its enough for 1080p mantaining a good console size and power consumption. 

Now, what do you think the next PS5 will bring us in terms of hardware specifications? I think next gen console should be able to handle at least 4k Resolution at 30 FPS to take advantage of new TVs.  What do you think should be the capabilities and hardware of the next sony console  if it comes arround 2019-2020 to convince you to buy it? 

Oh, this remembers me of a very funny thread from another user: gamrconnect.vgchartz.com/thread.php?id=144252

Well, we also had a discussion recently about the amount of RAM that is going to be used.
My guess is it will be x86-64 again with some custom hardware, nothing spectacular and nothing groundbreaking. Both Sony and MS will go this road from now on.

2019 would be the latest I think it might come out (Expect sooner).  But when it does I would expect:

-Something like an R9 770X or whatever would be like 8 times stronger than the 7870 in the PS4

-16 or 32GB of HBM memory bringing the bandwidth to 1 or 2 TB/s

-An 8-core CPU clocked at 3 - 4.0 GHz with much better IPC than the PS4's cpu, and a second quad-core cpu for background tasks.

-Full backwords compatibility with the PS4.

-Expect the PS5 to perform as well at 4K as the PS4 does at 1080p now with the obvious advantage of much better effects/AI/Physics.  60 FPS should also be at least decently easier for the PS5 to do than it is for the current consoles (Due to the faster CPU and RAM).

-Possibly a 1 TB SSD for fast load times.  Expect at least a hybrid solution.

Tagging this!

Why is it funny? He wasn't even that wrong. He said 4GB of RAM + 2 GB of VRAM, so it was 6GB and that was pretty close to the current 8GB (Sony almost went with 4GB). The GPU he said is absolutely spot on. The only part that was really incorrect was the CPU, but it wasn't a ridiculous assumption since that Cell processor did exist.

So he did get wron the CPU and a split memory architecture, RAM was close, GPU was spot on, not a bad prediction at all. The pricing at 500 bucks wasn't that wrong (X1 went with that), and with a Cell it would probably end up like that.

It will be 6x / 8x powerful than PS4 but dont expect 4k from it.

What makes you think that's enough to do 4K at 30fps? Thats a 4x increase in resolution, while ps4 already has trouble maintaining 30 fps with a 2.25 increase in resolution.

I hope you're right because by 2019 I'll be all 4K, yet my gut tells me there will be another gen of upscaling 1440p/1600p before we get native 4K.

32GB memory sure, memory is not that expensive. 1TB SSD nah, easiest to keep the cost down by including a cheap HDD. Somehow I also expect to see a 16 core CPU before going back to 3-4 Ghz. More focus on GPGPU as well.

Lol. Current gen barely gets 1080p. 1440p will be max.

Current gen barely gets 1080p but with much better lighting , textures, effects and antialiasing over a PS3. If the GPU is 8 times stronger than the PS4 as Captain_Tom points out, then it would have arround 1.84 x 8 or 15 Teraflops of computing power. If a Geforce GTX 980 or a Radeon R9 290X is playing 4K (mid to high quality, not ultra) and have arround 5 Teraflops and 240-320 GB/s bandwith, then a 15 Teraflops GPU with 1 TB/s Bandwith would be enough for 4k mantaining the quality of actual textures. I dont know if it can be done at 400 USS.

way too early to predict, tech grows exponentially, so there's no saying where we will be even 3/4 years down the line.

When ps3 was released, it would've been a dream that next gen consoles have 8gb ram
