God dang it, in my heart some of me wishes this were true so that maybe MAYBE, WiiU can get more multiplats...bah whatever, at least I have my Pokemon.

it would be a interesting thing to watch how developers treat the Wii U if that actually happens.

There would be no effect.

unfortunately you are probably right



“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.”

Who cares, as long i can watch my tv on the xbone, am good



Bet reminder: I bet with Tboned51 that Splatoon won't reach the 1 million shipped mark by the end of 2015. I win if he loses and I lose if I lost.

And more "insiders" confirm the downclocking of the GPU.

Oh boy this should be interesting.

Now I will try to explain the difference between the PS4's APU and Xbone's APU.

PS4's APU

* 8-core Jaguar CPU
* 18 CUs GPU
* Memory controller
* 3 billion transistors
* < 300 mm² in 28nm

Xbone's APU

* 8-core Jaguar CPU
* 12 CUs GPU
* Memory controller
* 32MB eSRAM
* Fixed units: Data Moves, etc
* 5 billion transasistors
* > 400 mm² in 28nm

PS4: $10,000 / 120 (80% of the 150 chips are good) = $83 per APU
Xbone: $10,000 / 50 (50% of the 100 chips are good) = $200 per APU

I don't how the cost of the Wafer used to produce the chips... I can guess a value from $5,000 to $8,000 (these are the cost I remember from the 40nm process)... and I don't know the percentage of GOOD chips or the real die-size of the Xbone or PS4 APUs.

A few corrections here. First, the initial yields likely are in the 20+x% region.  TSMC/GF are just starting with the production of the chips and initial runs usually start at very low yields. The calculation would roughly be $7000 / 50 = $140 per APU for PS4 and $7000 / 30 = $230 for XBox One (The manufacturers very probably lose money at this initial stage, only when yields go up will they recover the initial losses). Of course the wavers don't cost $7000 (probably very roughly $50-$150 per waver, that depends on waver type and quality used), it's the production that costs that much.
There is also a misconception running around on the web that eSRam is a problem on the XBox APU. This cannot the case. Memory is one of the things that is engineered with heavy redundancy in mind (there is a little more than 32MByte eSRam on the die, so bad blocks can be swapped with good surplus blocks, oldest trick in the world really). So eSRam actually INCREASES yields because errors in the eSRam block can mostly be "repaired". Both APUs have redundant parts and non-redundant parts (CPU, obviously, one bad core and into the trash the APU goes). The GPU is bigger on the PS4 die, but since only 18 of the 20 units are enabled, this part is redundant. In general, the XBox APU has more non-redundant parts so it will ever be more expensive than the PS4 counterpart.

I agree... and the numbers used are not real... I just used them to try to explain... I really don't know the real cost of the Wafer and how much chips can be made for PS4 and Xbone... but the last part is true Xbone's APU will be always more expensive than PS4's APU (5 billion vs 3 billion transistors... > 400mm² vs. < 300mm²).

I said it before and I'll sayit again: Sony just has superior engineers which results in better hardware. It really shows the lack of experience from Microsoft. It doesn't help if you throw endless amounts of money at the development. You just need the know-how to build a hich quality console.

That said, you'll still have fun with an Xbox One. If those rumours are true, it will be 720p @ 30f fps while PS4 will run games at 1080p with either more details/effects or 60 fps. But in the end, gameplay isn't affected at all. There will be no PS4 game that wouldn't be possible on Xbox One. It's just eye candy. Even with low specs, Microsoft can still win Next-Gen. It all comes down to games, not hardware power. So it's best we just wait for E3. IF Microsoft has some Megaton, people will forget rather quickly about lower specs.

Totally agree with this. This really depends on MS's E3 presentation. They need to show some exciting games not just more arcade/kinect/ sequels to already existing franchises. MS has seemed really out of touch lately.

If Sony fans can say Sony learned from their early mistakes this gen, then I have the right to say the same. that is all. I call propaganda until proven wrong.


you did not answer my question... wow and this is from some one that says sony fans are always deflecting :P

You know a lot about posters to say you are new...

 

OT

Its great that after a lull, we now have a negative thread where sony fans can gather to mock and declare instant doom and failure off yet another rumour.

In all the recent positive XBONE and MS game news threads over the last few days its been really quiet.

What was Pezus saying again?


*Shakes angry fist* Those damn Sony fans!



CBoaT over at GAF has leaked a lot of stuff before regarding... A lot of stuff. He has never been wrong.

He writes the way he does, to hide his posting style. He is an insider. He knows his shit.

Roughly translates to...

"Mods, you can remove "rumor" from the title. ESRAM yields are "troubling", to put it lightly.

This is factual truth.

Btw, you won't hear tech talk at MS' conference. And the tech cannot change at this point. They're stuck with it.

MS rushed, they were caught off guard by Sony, due to a failure in leadership."
