PlayStation 4 & AMD Radeon R9 290X GPU share the same 8 ACE ( Asynchronous Compute Engines )

Newly leaked slides from AMD's new Radeon R9 290X Hawaii GPU  reveals that the Volcanic Islands GPU will also feature 8 Asynchronous Compute Engines much like the Liverpool GPU inside of Sony's new PS4.   

Each of the 8 ACE's can manage up to 8 compute queues for a total of 64 compute commands, in comparison the HD 7970 only has 2 ACE's that could only queue 2 compute commands for a total of 4 & the Xbox One only has 2 ACE's but they also manage up to 8 compute queues for a total of 16 compute queues. 

Could this mean that the PS4's GPU is also a part of  AMD's Volcanic Islands family? 

Below is a diagram of the PlayStation 4 Compute, Queues and Pipelines from VGleaks 

From VGLeaks

"PS4 GPU has a total of 2 rings and 64 queues on 10 pipelines

- Graphics (GFX) ring and pipeline

• Same as R10xx
• Graphics and compute
• For game

- High Priority Graphics (HP3D) ring and pipeline

• New for Liverpool
• Same as GFX pipeline except no compute capabilities
• For exclusive use by VShell

- 8 Compute-only pipelines

• Each pipeline has 8 queues of a total of 64
• Replaces the 2 compute-only queues and pipelines on R10XX
• Can be used by both game and VShell (likely assign on a pipeline basis, 1 for VShell, and 7 for game)
• Queues can be allocated by game system or by middleware type
• Allows rendering and compute loads to be processed in parallel
• Liverpool compute-only pipelines do not have Constant Update Engines (presented in R10XX cards) "
