And while I'm at it, I don't think it's 240 either :p

I always thought it would make more sense to call the card GT 280 if it actually had 280 SPs. Though in the one slide, the area they highlight as "Thread Processor Cluster" is certainly smaller than what others have sectioned out. That would certainly lead to significantly more than just 10 clusters.

I don't think so. Why should the name of the card have anything to do with the count of any unit?

You know I was trying to figure that out too. The stuff they highlighted as a TPC we took to be a single TPA. Unless the guy doing the highlighting made a mistake....
 
The number of clusters is right, I just don't think it's 8 SPs per SM. Gamers won't care though.
 
Each SM has the same basic setup as one in G80 (and every other G8x or G9x chip). So 8 FP32 SPs each with a MADD plus the MUL/special. So it's 240 SPs in that respect. But there's more to it than that, ALU wise.

Blimey a dedicated double-precision unit?

Transcendental only double-precision?

Transcendental + 32-bit integer MUL?

Dedicated 32-bit integer units? Also used for texture filtering?

Jawed

Well, looking closer to the pic, it seems you're right, they highlighted just half (or a bit more) of what I would have called "a cluster". So what's in the remaining part? :oops:

What does the "same basic setup" mean? If G200 had the same basic setup, it would have had 2x8SP arrays per cluster, isn't it? :?:

Right, that's why I said per SM, rather than per cluster :) The changes I'm talking about are at the SM level (and then higher up at the scheduler, and then out into the RF).

Ehm, what does "SM" and "RF" mean? :-?
But the Thread Processing Clusters are still 10, right?
