Digital Foundry: Scorpio Spec leak - "might suggest console isn't the "true" 4k console as MS claimed"

Doesn't the 32mb esram have some advantages, like direct access to the gpu independent of the main memory bus?
How is 8 mb of L2 cache going to replace that?
Plus I guess games can be better optimized when not having to resort to tiling to fit in esram.

I guess it can adequately emulate it with the higher speeds of everything else for backwards compatibility, yet for real benefits games will likely need a scorpio patch.

It would be 16Mb of L2 cache, not 8Mb.
Jaguar in the consoles use a 2x2Mb configuration, for 4Mb.

And yes, eSRAM does have a few advantages, capacity for one.
But L2 cache is typically lower-latency, has more bandwidth. (We are talking TB/s a here.)

Too early to tell how that cache is configured, if it's shared with the GPU or not, or even if it's exclusive to the GPU. (I would assume not.)
Need more information before an educated break-down can be made.

The rest can be brute forced/abstracted easily to make it run at the same rate as an Xbox One.
Microsoft will probably take a software approach in the same place that Sony would take a hardware one, Microsoft has the software engineers.
