Would it be ok if I or someone else made a thread about the Pros & Cons of using a 2nd GPGPU in a console for computing?

Wasn't that the sweetvar stuff? also your link doesn't work.

Maybe he got antsy and asked a mod to remove it fearing repercussion.

I dont remember exactly what he said though.

I didn't see a post on this and I received this right after the Moody downgrade. Looks like Tim Schaaff is leaving Sony...

The changes continue at ailing Japanese electronics giant Sony, as Tim Schaaff, president of the firm’s online entertainment business during the massive data breach of 2011, announced his decision to quit at the end of the year.
Schaaff, a protégé of former CEO Howard Stringer, was hired from Apple in 2005 to become president of Sony Network Entertainment. During his time with the fruit-themed tech giant he was instrumental in developing QuickTime.

Schaaff will be replaced by PlayStation boss Andrew House

Does X-fire work well (better?) if it is done from a single memory pool ?

Also without the drivers overhead, can they removed the stuttering ? Maybe segment the frame into multiple layers instead of using the alternate frame rendering method found in PC.

It's not really X-fire if it has a good unified memory pool.

The problems with multi-chip rendering are all about communication. You can slice and dice the CUs themselves anyway you like, but at the end of the day, they need fast access inbound to textures, and outbound to rops.

X-fire (and SLI) is a chewing gum solution where the two chips have their own separate memory pools and a really pathetic communication channel between each other. Texture bandwidth is easily provided by duplicating all textures in the ram of both GPUs, rop bandwidth is harder, and typically managed by AFR, or in other words, by not even trying.

If the two chips somehow had fast access to an unified memory pool, they could instead work just like a single normal GPU -- both get their textures from the pool, both output pixels into the pool.

However, this is hard because providing that fast unified memory access would be rather hard. One option would be to have two symmetric chips with their own memory pools, with an added very fast bus between them. This bus would have to be as fast as each of the pools, in both directions at the same time, to never be a bottleneck. (You could probably cut it to half the speed and not suffer *too* much).

If there is going to be 2 GPUs with one being in the APU I really don't think it will be used in X-Fire / SLI with the main GPU unless there is one pool of fast memory. but if it isn't set up in that way I'm thinking that the GPU in the APU will be working with the CPU instead of the main GPU, kinda like the SPEs in the Cell chips.
 
Not sure if this is the right thread but anyway, according to Gamereactor and they seem to be 100% sure. There is ONE new console being launced next year. They have based this on what the boss of Activision Bobby Koticks has said. The only thing that they are not sure of is if it is the next PS or Xbox. So Wii U now in november, next year another console and the year after the last one will be released.

As much as I would like to see a new console next year, if we did not see one until 2014 because they were specifically waiting for certain technologies to mature (chip stacking, FINFET, smaller process node maturing as well as becoming affordable, 400mm wafers on the near horizon to help with costs, small LCDs with high pixel densities becoming extremely cheap, etc) I would be ok with that, especially if the 2013 console being released exhibits large reductions in current gen silicon budgets. If they are waiting just to wait/poor planning, well, meh.

If the latest vg247 rumor is correct and what sweetvar said is correct then the ps4 will launch first.
 
Pachter recently stated (no sources provided though) that PS4 will launch late 2013 and Xbox3 will launch between (IIRC) December 2013 and March 2014.
 
All rumors point to the fact essentially all the rumors being vague at best and outright fabrications at worse.
