Since many threads of comments have come up discussing about the price of the processors, I would like to share my opinion about the technology driven products. The products should be made keeping in mind reusability of the heavily priced components. Do you think it is necessary to have so many high end processor in every home residing in laptops, desktops, game consoles, tablets and many more. The gaming consoles with very varied interfaces should be avoided by the designers and they should use the standard interfaces used in the computers that way reusability of hardware will be more justified.
The PS4 GPU is also based on AMD Radeon cores. The big difference is the number of compute units: 18 vs 12 of the XB1, hence the roughly 50% difference in raw power (1.8 TFLOPs vs 1.2 TFLOPs) provided that they run on the same clock speed of 800MHz. Keep in mind that these numbers (on the XB1 part) are not official, just educated guesses.
Microsoft recently commented in an interview that they were able to slightly boost the GPU clock speed without thermal issues. Together with the fact that they are now reporting 1.31 TFLOPs in the slides, I think the estimations are not too far from reality.
Not surprisingly, Msoft says yields are "on or exceeding expectations"
Can't tell you how many times I've heard that but they make a good case that the chip has 47% cache memory array and a fairly regular graphics core (both repairable) and Nvidia and AMD both make even bigger chips.
I'll check on the yeild issue with folks at the conference today. They did say it was one of the largest die in consumer electronics--ironically the sort of thing I used to hear from Sony's Ken Kutaragi, Mr. Playstation.
My laptop has a piece of electrical tap permanently stuck over my built-in spycam.
With as much CPU/GPU power in the XBox1 seems to have, little parasitic programs might be able to operate almost invisibily. That somewhat scares me, post-Snowden-NSA.
There isn't any obvious malware monitoring going on my daughter's X360. I would hope that the next gen would have something like that. I would assume that users can buy things off the Internet with credit cards, thereby providing a "monetization incentive" for all the accomplished malware writers in eastern Europe and Asia (and other places as well).
