SO then u agree that bluray is worthless and shouldn't be in the system and they should just put in a dvd drive correct ?
I agree that both Bluray and HD DVD are probably 5 years too early to market as far as movies go. DVD-R's and other computer related uses are an entirely different matter though.
In the PS3's case, I would say it all depends on how many games use more than a standard DVD could hold, and how good those games sell to determin if it's worthless or not. If there are say, 3 "system sellers" that use more than a standard DVD worth of space on the disk, then yes, I would say it was worth including.
But sony promised 1080p games . 480p is no where near that . Broken promises like the xbox 360 hdd
480p is no where 1080p, but 20% of PS3 games supporting 1080p is still 1080p games, and thus, no broken promises. That's a little different from saying the 360 will include a hard drive, and there will only be one version of the ssytem, and then offering 2 versions, 1 without a hard drive.
They required all videos to be in 1080p for the games claiming in game footage or rendered to spec . If those games come out at 480p your going to bet alot of people would be pissed. Even if its fancy word work like ms they will still get pissed.
And what about the thousands of other games? Do you think some struggling developer is going to care what Sony requires from their videos that they use at press conferences?
Yet not every game will need fp16 . Actually we don't know yet if there will be any visual diffrence that one can see. However we do know from years of pc games that there are image diffrences at diffrent reses and fsaa lvls .
Not every game needs HDR, and as I said, Cell can provide the FSAA.
Can you post proof of that ? The cell cpu can use all the bandwidth to the 256 megs of xdr ram thus the ps3 can't offload the frame buffer to a seperate pool of memory .

What Cell "can" do and what it actually does are two entirely different things. Yes, Cell can use all of the XDR bandwidth, now show me the game that actually does that.
And like I said before, the 360 CPU is limited to 10GB/sec. You think the HDD makes a difference? How about comparing 10GB to 25GB for your CPU? Think that's going to make just a touch of difference to your games?
But I don't believe in making comparisons like that, because that's not how things really work. No launch game, and it's doubtful that any game is ever going to be CPU bandwidth limited on either of these systems. There will be a bottleneck somewhere else first, so there will always be XDR bandwidth to spare on the PS3.
Regardless of that you never added the edram numbers into your comparison .
I don't add numbers because I don't debate theoreticals that can never be achieved.
yet it is never factored in .
Yes it is. I'm just not going to be silly, and assume that Xenos will be passing 10MB of data to the Edram 50 times per frame while running at 60 FPS, which is what a game would require to actually use all of that bandwidth in that pipeline. No game comes even remotely close to that now, there is no reason to believe a game would in the next 5 years. Again, you'll run into a bottleneck somewhere else first.
Secondly the 10mbs of edram is allways there for framebuffer the same can't be said of the cell ram pool and bandwidth .
Actually, yes, it can. Even back when Cell was supposed to be both processor and GPU by itself, it still would have used that pool of ram as it's frame buffer, and RSX has the ability to access it simply because their PC GPU's can do the same thing.
As for hdr + fsaa problem it solves nothing since there is no proof that the rsx can do multi sampling with hdr . If its ssaa its just going to increase bandwidth consumption that much quicker and once again your into the limits for bandwidth .
You aren't paying attention. RSX would not be doing the multisampling, Cell would. You basically use 1-2 SPE's to preform the exact same function as the logic within the edram on the 360. Chances are, they will be sitting there idle anyways, so why not? Cell was designed to have this graphics processing ability you know.
ati had a break down of modern gpu bandwidth usage and framebuffer was pretty high up on the list .
But no where near
that high.
Keep in consideration the fact that the entire 360 system and RSX memory pool have the same bandwidth as a GeForce 6800 video card, but in the 360, that bandwidth has to be split between both the CPU and GPU. It's all video memory bandwidth for RSX though, and RSX can still offload the frame buffer to XDR.
not all compressions cost gpu performance. Some compresion schemes have hardware acceleration for it
Still a compromise. Instead of clock cycles, now you are using transistors to do the job, which increases cost and power/heat.
Unless you have infinite processing power, infinite ram, and infinite bandwidth, everything is a compromise, especially when you are on a $300-$400 budget.
Keep in mind that I am buying a 360, and called today to see about switching my preorder to the Premium package. I'm just calling it how I see it, and I see the HDD as a much smaller real-world issue that some members here seem to believe it is. If you were going to have misgivings about the 360, there are much more important issues to be concerned with.
