Xbox 360 have 4x AA enable at all times?

Anandtech also (according to what someone posted) said that it would support 1080p, but from what an interview said this is not true at this time.

I know for a fact it was stated that 2x is required. That was confirmed the night of the MTV unvieling. It can DO 4x AA, but I never heard it was required.
 
Before this turns into a PS3 <> Xb360 thread, I'll just say that I'd take 720p at 60Hz over 1080p 30Hz anyday. At this point, I don't think anyone knows for sure at what cost 1080p @ 60Hz comes.
 
There is too much conflicting information at this point.

BTW, the real meat of that article was a working unit which as the very least had (almost) final GPU.
 
I believe with 4x fsaa the r500 can do 16 giga samples (is samples right ?) so it seems to emply it was built for that .

It will be interesting to see.
 
The AA samples aren't stored in EDRAM. They're stored in system memory.

The framebuffer is split, so that only the filtered pixels are stored in EDRAM. When a filtered pixel isn't finalised, the pixel isn't a colour, but a pointer to the AA samples (to a memory address, forming the start of a linked list for the entire set of AA samples that make up the pixel).

PC GPUs must have been working by magic then to be able to do AA without eDRAM and just as much VRAM as the Xbox360 does!!

I think he meant that there wasn't enough ram in the 10MB framebuffer to store 4X AA samples at 720p.

I know, just teasing. I thought it was common knowledge that the GPU will be able to use system RAM for the AA samples.
 
I don't think the 1080p is something they'll utilize when the PS3 comes out. I more or less think that SCE is making the PS3 future proof. 3 years down the line they'll probably be 1080p @ 60Hz, you won't utilize it now....but when those TVs come out you'll be able to get a richer experience.
 
2x AA is "Free", 4x AA is "the sweet spot", at least that is what ATI's senior architeture of the part envisions. 1080p is not catered for by the display logic.
 
Thanks Dave. I hope most developers will opt for "the sweet spot" then.

IMO the vast majority of people will probably be playing next-gen games on past-gen TVs, so both MS' and Sony's angle on HD is a bit overemphasized.

HDTV has been catching on in the US lately, but I don't see that happening over here just yet. It'll take dramtic changes in prices and public awareness for that to happen...

Well the consoles are gonna be around for the next 5 years at least so it can only be a good thing to be future proof. Also, thanks to both MS and Sony's constant HD bragging, acceptance will increase a lot. And prices will come down.

I'm getting a Toshiba DLP TV in fact. Real real soon. No rush, i'm in the uk and i won't be able to watch any HD material untl next year. But it will definately happen.

Hard OCP chimes in about the R500 eDRAM:

"The 10MB of Smart 3D Memory can do 4X Multisampling Antialiasing at or above 1280x720 resolution without impacting the GPU".

That is a bit of overstatement, 4x will be very cheap - but only 2x will be esentially free. With 4x the framebuffer will be 14MB and 4MB of the main memory has to be used.

Edit: unless there are some other trick I am not aware of, but as the minimum AA is 2x I doubt it.

LB, Xbox 360 works with Monitors :D Just hook the puppy up to your PC Monitor. I am hoping they offer a letter boxed mode, that would work PERFECT on my 19" L90D+ 8ms panel (1280x1024). Just letterbox it and I would have 16:9! I hope they realize that some people on 4:3/5:4 TVs/Monitors may want to letterbox... I will take HiRez/16:9/Letterbox over HiRez/4:3 any day.
 
I love my dlp, except the damn color wheels make this noise, and I couldn't be arsed to fix it while it was still in warranty.

Anyway, mandatory AA is REALLY attractive to me. Bring on Xbox360!
