sounds to expensive. SOmething close maybe, but not all cores are the same, even from the same company. SO it having 8c/16t and close clockspeed is not everything. Can make core with half as much transistors.
Not at all... this is pretty much dead on the CPU in the next-gen consoles. The cache has already been cut down from the equivalent desktop part; basically its been quartered, from 32Mb down to 8MB. It's a 45W chip at full throt meaning at its peak 4.4Ghz clock and with its inbuilt GPU, the next-gen consoles will not be clocked that high ever, and would run at a steady 3Ghz-3.4Ghz range. This means the CPU will pull a max of 30W on its own since they would have their own much beefier GPU.
The finessing you suggest in core design is unreasonable, there is no need for that, as it stands the chip is already well withing thermal and power limits to fit into a console. To put this in perspective, if its 30W chip in next-gen consoles as is, that puts it at a power draw lower than the jaguar cores that are in the current-gen consoles back in 2013. And precedent suggests that both platforms went wth a "laptop" chip then, which is exactly what this chip is now.
Don't think they are going for a beefy CPU. They rather put the budget on GPU and RAM.
If you have ~140watts to play around with, you dont think they would spend 35watts or so, on the CPU?
Maybe they downclock them a tiny bit, so they dont hit 2.9GHZ under load, and thus use less power.
They don't eve have ~140W to play with... its more like around ~200W-220W. And that's indicative just by looking the SeX chassis, it's designed that way and that big for a reason. Cooling. That suggests that these next-gen consoles ae likely going to have the biggest cooling solutions we have ever seen in a console thus far, which suggests that clocks and thermals are going to be higher than what we typically would expect. That all translates to more watts.
Another way to look at it, if the PS4/XB1 pushed 170W+ on their cooling solutions back in 2013, what do you think you can expect with a cooling solution twice as big or efficient?
