Well unlike the 360, the X1's main memory offers mediocre bandwidth for the gpu.
Another benefit of Esram is it has higher bandwidth partially due to dualport nature of this type of 6T sram. If they had gone with dram not only would there be higher latency but there wouldn't be dual porting effectively cutting down on the theoretical peak bandwidth.
