As much as we all love PCs here its also very likely many of us also own a console. I've been a PS man since the PSX, so my next console will also likely be a PS. Title tells the whole story really, what are your predictions for the PS4? Preferably predictions with solid reasoning behind them please Not just "I want this and that" posts
CPU: Hex core Cell @ 2.2GHz per core
A lot of you may not like my prediction here, but the simple truth is Sony poured a LOT of $$$ into developing the Cell Processor and setting up manufacturing plants for it. It would not make financial sense to write off the investment costs and development costs of the Cell as a "mistake". So my prediction is a 6 core Cell CPU @ 2.2GHz per core built on a 32nm or 45nm process.
RAM: 2GB XDR2
Its not the smartest choice, but its the most likely choice. The memory controller of the Cell shouldn't require too much modification. DDR3 would obviously be the best choice because its so much cheaper, but AFAIK adapting the Cell CPUs memory controller for DDR3 would be very difficult. I would hope this time Sony design the PS4 with a combined memory pool, not a segmented one.
GPU: 1.6GHz nVidia RSX "Reality Synthesiser" w\ 2GB vRAM
I've chosen this as the PS3 already uses a nVidia RSX chip and it makes sense that a updated version of the chip would be used again as Sony have good relations with nVidia here. I would hope this GPU sports all the modern features and support we are familiar with, DX11, SM5, Tessellation, etc. At the very least I would expect DX10.1, SM4 and Tessellation.
Storage: 8x Blue-Ray drive, 320GB+ SATA3 HDD
Simple logic here, Sony poured a crapload of resources into developing blue ray, it doesn't make sense to abandon it so soon. Standard mechanical SATA3 HDD because their cheap as chips and give lots of space.
General Connectivity: USB3, wireless, all the modern standard stuff we are used to.
Nothing out of the ordinary here but for the love of all that is good Sony better not put the same POS wireless adapter in the PS4 as what they use in the PS3.
Well, thats my "prediction" if you will. Anyone else care to take a stab?
