Could PS4 and Xbox One have two more CUs in them than what we thought?

Just read this article at Eurogamer...

http://www.eurogamer.net/articles/digitalfoundry-can-xbox-one-multi-platform-games-compete-with-ps4

...and they speculated that PS4 actually has 20 CUs in it and Xbox One has 14 but in each console 2 are deactivated because of manufacturing yields concerns. Hmm, if that's true and considering how far behind Xbox One is in the GPU department they should just take the hit on yields and use all 14 of them. Won't happen, but would be nice.

lol people still care about articles written by Richard Leadbetter?

Here is a fun factoid for ya: Last gen both (at least I know the PS3 did this) had an additional CU core in order to circumvent yield issues. It's a neat trick, worked out terrificly (not sure if MS did it as well, I know Sony did it on Cell manufacturing).

Continuing this trend is pretty smart. Anything that can be done to lower the failure right of those launch boxes is a blessing in disguise.

It especially makes sense out of the very-similar-to-Xbox-One-GPU 7790 having 14 CUs in it.

Consoles can't have multiple chip SKUs to cover for manufacturing defects.

Looking at the Xenos chip, it only has 48 pipelines i.e. MS is on the edge with Xbox 360.

12 blocks x 4 = 48 pipelines.

We'll know the true nature of X1's chip in Hotchips conference. http://www.hotchips.org/

I already said that it's unlikely they would take a huge finacial hit by throwing away a lot of APUs if all 14 of the CUs don't work. Hence the reason they will only be activating 12 of them (Provided the author is right there is 14 of them in the machine to begin with. Neither of us know if he is or not). I'm well aware it doesn't make business sense to do it. I don't need you or your follower to tell me that. I simply threw it out there as a "Wouldn't it be nice for us" kinda thing.

14 CU X1 would be nice for Xbox fans, but we'll know the true nature of X1's chip at this year's Hotchips conference. http://www.hotchips.org/

During Hotchips conference, we'll know if X1's 5 billion transistor equiped APU/SoC is just a waste of silicon.

I hope that Hotchip's X1 doesn't troll everybody with a killer GCN.

I don't think that's going to be an issue this time. No matter how much people around here hate MS the reality is they've done some good things for console gaming; in this instance their approach has finally convinced Sony to go with straightforward hardware. Heck, Sony took it to heart so much they even outdid MS in the simplicity department this time. Both consoles have familiar architectures. Xbox One is more complicated but still pretty basic. I'll tell ya though, it's bizarre to me that a Xbox console has such a weak GPU compared to the competition. In the past it was always Sony putting everything into the CPU and overlooking the GPU and MS going balls to the wall with the GPU. But MS faltered with the GPU this time in a big way.

If the CUs are disabled they are disabled for a reason and just simply activating them wouldn't be a good idea. If they wanted more CUs they would have just got a different chip.NFJSupreme

No, I don't think you understand how this works. Let's say they make manufacture 1,000 chips. Depending on the yields, out of that 1,000 let's say 500 of those chips have all 14 CUs working properly. Maybe 700 of them have 13 CUs working. And maybe 950 have at least 12 CUs working. 

If MS uses 12 CUs, then they can use 950 out of 1,000 chips and only throw away 50 bad chips. If they decide to go with 14 CUs then they could only use 500 of the chips and would have to throw away 500 chips. 

That would be super expensive to do because remember MS will be manufacturing millions of consoles. 

AMD on the other hand doesn't throw anything away. Because if a chip has 24 CUs for example then they use it for the 7870. If only 20 CUs work then they put it in another chip and so on. They end up losing very few chips.

That's not what you said and that's not what this thread is about. 

Obviously MS had a good idea that with the yields they would only have 12 CUs. However, what the OP is asking here is if MS should eat the cost and use all 14 CUs just to get more power out of the chip.

The reason the OP suggested this is because he knows it's too late to go to a different chip design and MS could just throw their money around and get the 14 CUs. 

You said that enabling 14 CUs wouldn't be a good idea insinuating that it would cause some sort of RROD type of hardware failure. 

It will not but it would be super expensive and not make any sense so MS will not do it. 

"lol people still care about articles written by Richard Leadbetter." I don't...and this debate is debunk for one simple fact how can we trust by word of mouth.

I agree with you that Sony has mislead us in the past. The PS3 was a bunch of hype as was the PS2(hardware wise). 

However, this time this is not the same. The PS4 has a considerably more powerful GPU and a lot faster and better RAM. These are simple facts. 

The X1 will have much better features(movies, tv, music etc.) and online just like always but in a pure gaming sense, the PS4 is a more capable machine.

Obviously MS had a good idea that with the yields they would only have 12 CUs. However, what the OP is asking here is if MS should eat the cost and use all 14 CUs just to get more power out of the chip.

The reason the OP suggested this is because he knows it's too late to go to a different chip design and MS could just throw their money around and get the 14 CUs. 

You said that enabling 14 CUs wouldn't be a good idea insinuating that it would cause some sort of RROD type of hardware failure. 

It will not but it would be super expensive and not make any sense so MS will not do it. 

At least someone understood what I was talking about. :) But yeah, it won't happen. Would be nice but I know odds are around 99.99% against it.

And you are as wrong as he is..:lol:

The xbox one is 1.23 TF not 1.3, is a 7790 with 2CU less and a hell of a speed clock downgrade,just like the PS4 is a 200mhz 2 CU less 7870,the 7870 XT is another thing.

The test that most closely resemables a comparison of both GPU are the 7770 vs 7850 the TF count in both cases is very close.

Well, the 7770 only has 10 CUs.

Yep but it has 1ghz clock speed while the xbox one is say to be 800mhz and by some leaks even less 750mhz.

Compared to X1, 7770 has less on-chip SRAM type memory i.e. register file, L1 cache, local data storage, global cache, L2 cache and 'etc'.

7770 = 1 billion triangles per second @ 1Ghz

X1 = 1.6 billion triangles per second @ 800Mhz

In regards to relative narrow performance gap, my view is similar to Richard Leadbetter.

Doesn't surprice me you are as biased as he is..

Comparing the xbox one GPU with the 7850...:lol:

And the PS4 one with a 7870 XT..:lol:

Not even a full 7790 can be directly compare with the xbox one,it doesn't have 14 CU nor has 1Ghz speeds.

I thought it was strange to use those cards for comparisons as well until I saw that they downclocked them to 600 mhz. Then it wasn't so bad.

tormentos has problems with the little details. :lol:
