How does that work with Xbox One X then? It has 6 teraflops and many multiplatform games have been hitting native 4K.
Think about the base it has to work with. Those same games have to run on a base XBO. Not just the S, the OG one too. I didnt realize it til now, but this line from the OP might help explain it:
It's reasonable to assume that Timothy Lottes is speaking in terms of a stable 3840 x 2160 image with zero fluctuation. It had not dawned on me before today that the target for native 4K on a mid generation PS4 might be higher than the benchmark for a mid generation Xbox console when taking into consideration the power of their respective base GPUs.
Mark Cerny himself when asked if 6 teraflops would be enough for native 4K without compromise said it would require a GPU closer to 8 teraflops. Presumably he was thinking of PS4 to PS4 Pro when he offered that answer.
Base PS4: 1.84tf
OG XBO: 1.31tf
One S: 1.4tf
The AMD guy seems to be saying you need 4 times the tf of the base console gpu. 4 times the OG XBO is 5.24, the One S is 5.6.
4 times the base PS4 is 7.36
We have to remember the games have to run on the base consoles too. Then think about the details, effects, frame rate, etc that be in base PS4 games vs base XBO games for multi platform games. Think about all those DF face off threads for the base consoles.....
I assume he specifically said PS4 title for a reason.
But, that video is Forza 7 PC, all settings maxed out and 4K/60 vs GTS, 1800P on the Pro. That video to me does give insight. For one the minimum PC requirements for Forza Motorsport 7.And I wonder what the specs of the PC was in that video.It's of no use to compare first party games because that doesn't tell you much. Nobody knows how GTS would look like on an Xbox One or how Forza would look on a PS4.
I think 4x is only the role of thumb. Microsoft already said that you don't need to multiply every resource to achieve native 4k.
That may be true, I seriously have no idea, but look at the the OG XBO and One S gpu times 4. Its easy to say that when they are already over it for the gpu tf.
