First let me say that I respect your opinions, you actually read the cites and come up with valid arguments.I give up, I'll just wait for the teardown.
But don't you think they'd mention this? Or mention this supposed second GPU?
Why would Cerny play down this second cpu as an I/O and file management handler if it's part of this amazing Media processor you're describing?
First, Game mode is not regulated and the latest PS3 has a 61 watt min (min should be = EPA regulated system mode of 40 watts at GPU active UI) and 95 watt max. PS4 may have a min of 60 watts (That's a guess but remember the WiiU is 37 watts.) with a Max of 140 watts using the AMD GPU and nearly 10X more powerful than the PS3.
Streaming IPTV on PS3 is near the Max power rating or about 85 watts (EPA reg is 50 watts) and the PS4 using the AMD GPU would be on the order (with accelerators) of 40-60 or if using a second GPU on the order of about 7-10 watts.
They haven't mentioned a HDMI-in (not necessary if using RVU and HDMI-in is not a lock for this reason) or that they will be supporting RVU or that RVU is going to be the hook that allows them to own the living room. The PS4 looks like it's going to be the most powerful game console this generation and so far this is about gaming.
It's not an amazing media processor, it's what is going to be standard. Wake on voice and gesture and wake on Lan, AOAC in the first home platform serving to all CE devices in the home added to RVU, XTV and the most powerful game console GPU......
That's the biggest issue I have with the document. These regs start in 2008 with a three tier phase-in and with feedback from Game Console Manufacturers. To get a better understanding read the following:iLo said:Given the lack of time stamp, this failure to live up to EPA: was it before or after the announcement of the current specs?
Energy Star EPA sponsored Voluntary compliance standards Three tiers starting with tier 1 2010
There are EU power regulations for Always on Standby mode with exceptions for "special features". Standby is 500mw but special exceptions are allowed and I have not been able to find the power that is authorized. It applies to the PS4 and Xbox 720. The always on mode for the Xbox and PS4 is not required to be 500mw, read the exceptions and use cases. One has a game console able to turn on a Blu-ray player and control as well as play the blu-ray in the player; RVU should allow such a use case.
Joint power mode paper from all Game console makers.
Response to the above paper from EU energy conservation groups
EPA Publishes Voluntary Criteria for ENERGY STAR Game Consoles
It costs the Manufacturers money to comply with EPA EnergyStar regulations and if you read all the above you see them whining and trying to set levels that they can meet without having to spend extra to comply.
The first Sony patent dealing with 2 GPU for power savings is 2009 (the first EPA proposals were in 2008), the last building on the previous is Jul 2012. So Sony knew they would have issues with one GPU early on.
Additionally the Game console must meet STB feature requirements for Computers (which are less stringent but are equal to the above).
Continuation of the discussion on SemiAccurate.
Consider ARMs big.LITTLE and Sony's big-little GPU patent. Consider AMD's HSA and the first third party IP they put in their SoCs is ARM/Trustzone. Consider that the Durango is a Windows 8 AOAC game console and AOAC is a Power saving Tablet feature. See a pattern?
