The Xbox One System On a Chip is 363 mm², contains five billion transistors, and is being manufactured on a 28-nanometer process by Taiwan Semiconductor Manufacturing Company. The Xbox One SoC includes 32 megabytes of on-chip storage and 47 megabytes of high speed embedded memory (eSRAM), which is similar in design to the Xbox 360 GPU. The PlayStation 4, on the other hand, foregoes the eSRAM and relies on higher bandwidth GDDR5 memory. The Xbox One SoC will provide 204 gigabytes per second (GB/s) of bandwidth internally and 68 GB/s externally.
wow then they already knew the specs and performance before Microsoft. Gotta hand it to them. Hell based on your date they even knew about their upgrade in clock speed.
