Creator of FXAA says PS4 could be years ahead of PC, new Xbox may have memory bandwidth issues

Timothy Lottes, the creator of FXAA, is concerned about the next Xbox having memory bandwidth problems and thinks the next Playstation may be better designed for the future. (Industry, Microsoft, Next-Gen, PS3, Sony, Xbox 360)

Memory Bandwidth issues never stopped the Ps3 so i doubt it will be a big problem.

PS3 had XDR RAM, the pool was just split. So I'm not sure what your point is. This - purportedly - has unified DDR5 architecture and no OS overhead to code through. You're basically sending instructions right to the components, CPU, GPU, on a base level. You can't even do that on PC, which is why this could be so awesome. MS - if we're following the same information - is going with a rather elaborate OS and doesn't care too much about performance as much as features: Kinect, Skype, etc.

Assuming any of this information is true it will be PS4/ PC > 720 > Wii U. With a clear distinction being made between PS4/ PC and the rest early on. Can't wait to see what gets revealed this year. We should have some answers soon.

a badly coded game is a badly coded game no matter the system. a really bad example

I guess we will see but there is no way in hell the next xbox will have bandwidth problems. The 360 didn't so i don't expect the next will. The amount of RAM is important but how you use it is even more. We don't know the final specs of neither. For all we know, they both could have 8 GB of RAM. Even if this is true there are ways you can make up for that issue just like sony did with the PS3.

If its DDR3, it will be as starved as the Wii U is for bandwidth. That's a fact. 360's saving grace was its EDRAM buffer.

"On this platform I’d be concerned with memory bandwidth. Only DDR3 for system/GPU memory pared with 32MB of “ESRAM” sounds troubling. 32MB of ESRAM is only really enough to do forward shading with MSAA using only 32-bits/pixel color with 2xMSAA at 1080p or 4xMSAA at 720p. Anything else to ESRAM would require tiling and resolves like on the Xbox360 (which would likely be a DMA copy on 720) or attempting to use the slow DDR3 as a render target."

Do read the article before posting next time. That's the pertinent excerpt since you can't be bothered.

I did read it. I also know not to believe any rumors on the internet that claim they know what the actual specs and what type of RAM is being used. There is still no concrete proof of MS using DDR3. Its all just rumors. I'm not as naive as you and others are. And next time before you comment please read my entire post. I Clearly stated:

"Even if this is true there are ways you can make up for that issue"

And that is true. Console hardware and PC hardware don't have the same performances. This guy is talking PC performance. He is only speculating just like 99% of the whole internet is doing. The only people who can comment accurately are the ones who know the actual specs.

As a PC guy who knows hardware to the metal, I spend most of my days in frustration knowing damn well what I could do with the hardware, but what I cannot do because Microsoft and IHVs wont provide low-level GPU access in PC APIs. One simple example, drawcalls on PC have easily 10x to 100x the overhead of a console with a libGCM style API.”

That is what you should be interested in.

Bubble for "helpful". I'd add one for "actually reads content prior to posting" too, if I could :)

" this next Xbox will act like a boat anchor, dragging down the min-spec target for cross-platform next-generation games.”"

Yikes i hope it isn´t true otherwise multiplats will be dumbed down quite a bit to work on the 360.

I doubt any of this garbage is true nothing but hearsay.

What did you create in this industry?
glennco  +   453d ago
he is a customer. gamers are required for this industry just as much as developers.

I'm a console gamer. And for the next playstation to be ahead of PC is impossible. Look at the GTX 600 series.

chukamachine pointed out why this is the case above.
Take a read of his quote from the article.

In a nutchell: You may have an AMD GPU with a thousand cores but developers will never be able to use it to its fullest potential.

"Creator of FXAA says PS4 could be years ahead of PC"

-sure, a pc from 2006

next gen ps4/nextbox will be years BEHIND current pc's and you are only setting yourself up for nerd tears if you think otherwise

my pc right now can play games in 2560x1600 with 8x aa

i 100% guarantee ps4/nextbox will not

you will see 1080p max, with many games in 720p, 768p, 900p, and many other wierd non standard resolutions, but at least i hope 720p will be the minimum unlike this gen

next gen consoles will not even be capable of crysis 1, dx10, ultra high, in 1600p

it would make them catch fire

that said they will be a giant leap over last gen ps3/360, just don't expect anything near high end pc and you'll be fine
