Forums - Gaming - PS4 & Xbone APUs Die Photos

If only MS had enabled those two redundant CU's (as they were in discussions to do nearly until launch). They then would have had over 1.5 teraflops, and with more CPU speed and peak bandwidth too boot. At best PS4 might have been able to wrangle a tie in performance (although the PS4's ROP edge might be big).

So MS easily could have had more power than PS4, the same size APU, AND a much cheaper DDR3. Great engineering.

And if they enabled them, they would have had even lower supply for launch.  Disabling them allows them to use the chips, even if one or two CU's are defective.  And even if they did Sony would still have 4 more than them, as well as more ROPs.  The gap would still be there in favor of the PS4, only not so large.

This can't be right, where is the dgpu?



“It appeared that there had even been demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. And only yesterday, he reflected, it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it.”

What purpose is that SRAM between the two Jaguars?

I like the way you made the PS4 die photo bigger :|

- from a fellow fanboy ahem :)

The chipwords picture is bigger PS4 chip is small... even if I scale one of the picture there is no way I can do the right size ratio.

Just to have a ideia the Jaguar Quad-core square have similar sizes.


Easiest thing would of been to put them into 1 image and scale one till a radeon core is the same size.

Maybe not to scale but you can definitely see that the Jaguar Cores are very similar and that the reports about the respective graphic cores were accurate. The SRAM has eaten up a lot of die area on the XBox APU that could have been used for more graphics cores. Sony's gamble with GDDR has paid off in Spades.

I think MS could almost double the GPU CUs with the space of eSRAM 24 CUs easily.


With 24 cores the POW would be quadriple, they would need GDDR5 at a higher clock than the PS4´s to not bottlenecking and bigger/faster CPU cores to gain performance balance.

The Xone would be a small nuclear reactor.
