Depends greatly on what you are running. On some of my own benchmarks the steamroller is half as fast the sandy bridge. I think it's safe the ipc is still way behind intel. This was running integer code so this eliminates half the floating point units being the issue and at the same clocks.
That should be worse case scenario. The benchmarks released by AMD could be contrived and massaged so to speak seeing as blender is open source. We'll see in about 10 days.
Well, one jaguar core is supposedly about a quarter as powerful as one Core i5 2500k core so if Zen is only as powerful as Sandy Bridge then 8 jaguar cores could be roughly equal to 4 Zen cores. However I'm hoping the next-gen consoles will feature at least 8 cores maybe on 7nm.
Of course it's pointless. I've got this theory though that to get a true noticeable leap in the types of games you play you need at least a consequent 5-6x leap in cpu performance. I think Dead Rising on the 360 was the first game to show something that could not be achieved on the previous gen...
But the netbook cpu inside the PS4 (and the One) is terrible for AI. Of course that was the best choice then because Zen wasn't available but still. DDR3 is a better choice for scattered read/writes.

Microsoft are a software company so it's no surprise they created a system more biased towards the cpu, with DDR3 lower bandwidth, lower latency ram vs DDR5 high bandwidth, higher latency ram, and Sony being a primarily hardware company chose to focus on the technical specs. In many ways the One...
Don't underestimate the power of word of mouth. If someone goes into Game and asks "So, which one is better the Pro or the Scorpio?" and they say "Well the Pro is a great machine but the Scorpio can play Street Fighter in native 4K with HDR" Then even if they don't fully understand what that...
I'm not so sure. I mean wouldn't it be annoying if when PS5 comes out you couldn't play Rise of the Tomb Raider in full 4k Glory over checkerboard rendering through a quick patch? Certainly I think there'll be a demand especially if Scorpio owners are already playing the game in 4k.
That's exactly what I meant. Whereas existing One games should be an easy port from 1080P (assuming they run at 1080p), Sony customers will have to wait till PS5 to get unrestricted 4K.
It's all relative as Mr Einstein once said.
With Scorpio a year away and a confirmed spec of 6TFLOPS on the GPU which is ~4x the gpu power of the current One, this is a good 4:1 match to the jump from 1080p to 4k, whereas the PS4 Originals higher specs of 1.84TF would need something on the order of 8TF's to provide uncompressed 4K...
