Predict: The Next Generation Console Tech

[DieH@rd]

according to the leaked specs HD8850 is a 3 TF, 130w card.
i have my doubts.

Minus ~30W for GDDR5, mionus ~20W for lower clocks..
APU: 80W GPU section + 20W CPU section +little more for special sauce.... Its dooable.

 

[Proelite]

If i had to bet it would be on the 18 cus rumor, 1152 shaders.

Yep, I guess 8830 is what I really meant.

doable, but not probable.

aegis?

 

[Inuhanyou]

Aegis hasn't said much about direct specs

Looks good to me. Let's say it's 2TF instead of 3 for the 8850 to be more modest.

APU 80w (standard Kaveri @ 100w - 20w console efficiency)
GPU 80w
Other, RAM, HDD, USB, etc 50w
=210w

Should put us above 2.5 teraflops.

 

[DieH@rd]

Nah, eigh Jaguar cores, beefy 88xx and secreat sauce. All in one APU.

Instead of downclocking an 8850, how about going with an 8830 which would be 2TF at normal clocking but would need less die space (230 vs 270). I mean just put the number of CU that fits in both TDP and target die space. Is it worth it to get a larger die and downclock it?

That would come well under 200w then. And the PS3 fat chassis eats 200w for breakfast.

Besides, they don't need to worry about stacking so much if it's just an APU and dram. But they are worrying so we can be sure there'll be multiple logic dies in there. APU + GPU

Sure I suppose so. Hopefully AMD didn't job them as much as Nvidia did and gave them their most efficient GPU tech as of end of 2013. Adjust clock and voltage to hit the sweet spot and see what they end up with in TF.

Also, if it does end up in the stack, TDP will be lower by default because of less volts needed to power it. So theoretically they can drop the volts and clocks and still attain default performance.

And the secret sauce is...

I would like a hardwired physics engine.
Whatever happened to dedicated physx chips? Any chance for a come back in the form of a secret sauce for consoles, maybe some kind of Havok-on-a-chip?

 

[Inuhanyou]

secrets with lots of sauce?

Doubt it. Nvidia bought Aegia and absorbed their middleware into their product line. As GPUs get more general compute structures they'll only become more suited to such operations.

I even remember the dedicated AIseek Initia AI processor that never saw the light of day.

 

[Proelite]

As I thought, Charlie on Semi-accurate is a semi fraud. We'll see him exposed soon enough.

 

[Bagel seed]

Secret sauce should just be FPGAs.

many modern FPGAs have the ability to be reprogrammed at "run time," and this is leading to the idea of reconfigurable computing or reconfigurable systems — CPUs that reconfigure themselves to suit the task at hand.

..

Advantages include the ability to re-program in the field to fix bugs, and may include a shorter time to market and lower non-recurring engineering costs. Vendors can also take a middle road by developing their hardware on ordinary FPGAs, but manufacture their final version so it can no longer be modified after the design has been committed.

In other words, the console is Skynet :O

Because he claims less than 8GB RAM for Durango?

Yep, and his Oban PPC crap a year old.

Yep, and his Oban PPC crap a year old.

Do we really know 100% that Durango has 8GB though? Same for Orbis's purported 4GB GDDR5.

I'm not counting my chickens yet on any of the specs.

You can count on Charlie as being unreliable, a fact well established and accepted by respected members of this forum.
