Lengthy interview on Xbox One architecture

#11SoulTrapperPosted 9/22/2013 7:18:48 AM
Interesting article, I do have one problem with it:

Tying into that previous block, Digital Foundry's own analysis came to the same conclusion that MS presented: that more CUs does not linearly scale to more power. They had a mock-PS4 PC (with roughly the same specs) and a mock-XBone PC, and despite the PS4 having 50% more CUs, it only yielded a 24% advantage. While this is in no way saying that the GPU in XBone is superior to PS4's, it means that if MS is smart with optimization and Sony isn't, any performance gap in the area of GPUs would be largely mitigated by the time final drivers roll to devkits.

So pretty much all of the talk about the GPU is theoretical BS assuming that Sony doesn't know how to optimize.
If they do, the PS4 will possibly be more than 50% better.

I don't know enough about the RAM talk to comment, but it sounds as though what was already said by Cerny and multiple devs: it's harder to program for.

Don't expect this to get any attention, this is pony territory.


So you're saying there aren't any people interested in the xbox?

The only differences between the two consoles will be minor at best. Both MS and Sony chose to go different routes to get similar results. Sony went for raw power and MS went for a more efficiency.

This article confirms several things we knew:
1) The PS4 unified memory approach is easier to program for than the Xbone
2) Most of the fancy audio HW in Xbone is reserved for Kinect processing
3) The 218GB/s number Albert Pennello came up with was totally bogus. The 204GB/s number is unachieveable on actual code. The best real code will ever do is 140-150/GB/s, and that's only if the memory access pattern of read/writes/banks is perfect. Otherwise, you get 109GB/s.
4) The Move Engines are Microsoft just renaming DMA engines which have been around for decades.
5) Only Xbone has a an HDMI input, which helps make it the "center of your home entertainment system"

Thank you for the link and explanation (TheApd_Returns) and Microsoft has truly outdone the competition with the design, power, and functionality of Xbox #1.

Xbox #1 is true Next Gen and we deserve it.

Xbox is better then expected. Awesome
Hopefully they tell us more about the hardware on the 26th.

Don't choose a console because of price, hardware or popularity. Choose a console because it has the games you want. For me that choice is X1.

lol

if you're going to quote someone else, actually quote them

As far as the topic, this only proves that MS should have gone with GDDR5. Easy 176GB/s > kinda complex ~150 GB/s

Reading this, it's clear PS4 will still be more powerful and simpler to develop for but MS has made sure it won't be too noticeable

So you agree with the statement...

Good now this thread can move on as PR talk.

The one thing that I got out of the article was how similar the programming will be compared to the 360. People made it sound like accessing the eSRAM was going to be some act of god. But in reality its something that that devs have been doing since day one on the 360 so the transition shouldnt be hard at all.
