ps3's blueray vs xbox's DVD

[AG!]

-In a double-layer DVD for Xbox 360, 7GB is usable by a game. The transfer rate of the DVD drive is 15MB/sec max, 10-12MB/sec average. The seek time is 115ms, switching layers takes 75ms. Loading 512MB data takes 34 seconds.

What I'm looking at here is the transfer rate of the DVD drive in the 360. its 15MB/sec (MEGA BYTE PER SEC MAX), average transfer rate is 10-12MB/sec.


Now lets look at blueray

Parameters
BD-RE
Storage capacity (single-layer) 25GB
Storage capacity (dual-layer) 50GB
Laser wavelength 405nm
Numerical aperture (NA) 0.85
Protection layer 0.1mm
Data transfer rate 36.5Mbps (1X)

DVD's can span over multiple DVD's (when games get that big anyway).

However, I wanted you to focus on the transfer rate of Blu-Ray, considering the ps3 will have a 2x drive, the transfer rate will be 73Mbps (MEGA BITS PER SECOND), their are 8 BITS in 1 BYTE so the equivelent (MAX) transfer rate will be 9.125MB/sec. The average will no doubt be around ~5-7MB/sec.

I don't know how the ps3 will stream better physics/graphics etc (given that both systems have 512MB of RAM) at a faster rate than the Xbox360. A slower transfer rate does mean there will have to be compensation somewhere, where exactly? I don't know.

Looks like DVD's are the way to go, that is until 3x bluerays / HD-DVD's appear, looks like MS might be waiting for this...

It is odd how Sony touts the Blu-ray possibilities when the read-rate is slower than standard Dvds. Sure, you get more data storage, but at this point, with slower load times. Of course technology will improve with time, but if they plan to let the PS3 launch with the current x2 Blu-ray drive (and this looks true), then I see it as a conundrum for the progress of the gaming community; i.e., you get more storage space but at cost of a slower disc reading pace.

For xbox360

Loading 512MB data takes 34 seconds.

For the ps3, it will take 56 seconds. (512/9.125=56)

As Grindstone pointed out, not only will there be slower load times, the physics engines are created to stream data off the media, this would mean a significant impact on the physics of ps3 games when compared with the xbox360.

Well, here is something intersting. Mainly the second paragraph.

The DVD is currently better, but if we could get an upgrade to 4x on Blue-ray, it would win out.

http://www.blu-ray.com/faq/#1.1

1.12 What will a Blu-ray Disc recorder cost?

As with any new technology, the first generation of Blu-ray Disc recorders will be very expensive, but the prices have already begun falling. The Sony BDZ-S77 is currently priced at 220,000 yen ($1,965), while the Panasonic DMR-E700BD is priced at 195,000 yen ($1,742). The discs required to record high-definition video are priced at about 2,000 yen ($18) per disc. The explanation for the high retail prices is that the recorders are targetted for businesses and enthusiasts rather than regular consumers.

According to the Blu-ray Disc Association, the overall cost of manufacturing a Blu-ray Disc will in the end be no more expensive than producing a DVD. The reduced injection molding costs offset the additional cost of applying the cover layer and hard coat, while the techniques used for applying the recording layer remain the same. As soon as manufacturers start mass production of blue-laser components, which is expected to begin in 2005, the production costs should fall and eventually be within 10% of DVDs."

yeah for games I dont care about high capacity discs, I really dont mind switching to a disc 2 after however many hours of play, I'm not THAT lazy. Now if your talking about movies on my HD tv, heck yeah bring on Blu ray I'm all about watchign some TRUE HD movies, but for games I really dont care one way or another

[TRouBLe]

For what we know untill now Blue-Ray is not needed. We can still store games on one DVD disk. There's gonna be a while for the games to become bigger and even then there's the solution of two DVDs.
Paying 100 bucks for the drive and bout 20 for each game when it's not really needed, is something i don't wantto suffer.

Well, I posted this just a minute ago. But, I don't think you read it, so I'll post it again just for you (read below). In other words, the discs will COST THE SAME! The drives will cost more money because of the R&D (research and development) but soon drop to a normal cost.

G4everX, your dreaming.

Let me tell you a few things about reality. What you see there, is a typical case of PR. When you bring out a product, you are not going to say that the media is going to stay expensive for a long time. No. You want the best of publisity, and you always write in the most optimal way you can.

Look close how they sentence is written. A typical trick.

"As soon as manufacturers start mass production of blue-laser components, which is expected to begin in 2005, the production costs should fall and eventually be within 10% of DVDs"

Notice how the date is ahead of the production cost. It give the impression that the price will drop in 2005 to 10%. In reality, the key is: "eventually".

"eventually" can mean now, next month, next year, next millenium. Now, thats the PR stuff.

Reality from a production point of view is something way differend. At this moment all the media producers are dvd producers. In other words, MS can go out, find a cheap & qualified producer, and start having its dvd's made for a few cents / dvd. Now, blu-ray is so rare, that the amount produced is maybe 1 blu-ray disk vs 1.000.000 dvd's. With a situation like that, price's are expensive. There is no mass production, no real competition, expensive machines, others need to be retrofited, changes in the production line, running 2 seperate ones ( dvd & blu-ray ) also increases costs etc.

15$ a 20$ is a rather accurate picture for media price ( based on the initial price's for cd & dvd's ). Lets say that its going to cost Sony 10$ / blu-ray. With dvd's well below the 1 $ mark, but for comparrision case, lets say its 1$.

Sinds all games fit on 1 dvd, they sure as hell will fit on 1 blu-ray. There is only 1 game that does not fit that we know off. Now, thats going to make every game 9$ more expensive. So, what will the game developers do. Charge the 9$ to the gamers, or eat the hit up themself. I suspect the first. That means a game will cost 9$ more then a xbox game. But, if you buy 5 or 6 xbox360 games, you get almost a 7th free compared to the PS3. Gamers do notice difference's like that.

Now, the hardware discussion is also a thing like that. Sony will eat up maybe 100, 150$ in hardware costs, but in general, thats about the max. When you know that the blu-ray reader is expected to be 100$, vs a retail toshiba dvd-rom what is 18$ ( note: thats current store price ). Thats another 80$ on the console. All those extra's like that hd. Sinds there is going to be one version, that means you end up with a expensive model already.

I need to admit, while i'm not found of MS, they sure as hell are pulling off a nice launch.

- Lots of PS2 titles are now Xbox360 launch titles
- Second wave of other big hitters around the time of the PS3 release.
- A cheap core version ( who will look dirt cheap vs a PS3 Premium ( and expected to be only version )).
- Cheater price's on both versions ( Core / Premium ) then the expected PS3 price.
- Cheaper Media price's = cheaper games then PS3's.
- Six months of lead time, and most people dont have the habit of buying 2 console's. In others words: a sold xbox360 = one less PS3.
- Launch during the best selling periode of the year. While the PS3 is in the mid year release.

It all starts to add up to a nice "strike" against Sony's market shares before they are even out. Even IF Sony can release the PS3 sooner ( what i dont expect, sinds it was confirmed that the production of the GPU wasent even started a month or 2 ago, while the xbox was already bussy ). There just isent any indication. Last interview i read of a developer clearly stated there focus on the xbox360, and they dident have time for the PS3 development.

This media pricing is just another bad thing for the PS3.

Argentus, your a little ticked arn't you?

I know what the word eventually mean's, and you need to cool your jets and not piss others off.

Another thing to mention, is that the PS3 can play DVDs as well. If a company doesn't need the extra disc space, they can just put their game on a DVD.

Ticked? Not that i know.

And a nice tip, dont change large parts quickly after you post them

Re-read what I posted, and you will notice the a similar word to "eventually".

In other words, the discs "will" COST THE SAME!

Instaint Email ... just loving it

[G4everX]

I was actually being rude, so I changed the post to make it sound like I'm not a b****. Sorry about that.

[xpitbull]

I dont really care who wins, is more popular, or whatever. I just want those corporate gigants to fully expand and challenge the power of the new media

[The Ultimate Girl Gamer]

Remember that these are not regular DVDs, there HD DVDs.

[Diamond]

Most of you guys are really bright... I just wish you could all spell better. Oh well, who am I kidding? I've seen the Sony related forums... What a mess! Might as well learn Hebrew.

Anyways, I pulled this off the Blu-Ray F.A.Q.

"Current technology

2.1 Will Blu-ray replace VHS?


Yes, that's the expectation. The Blu-ray Disc recorder represents a major leap forward in video recording technology as it enables recording of high-definition television (HDTV). It also offers a lot of new innovative features not possible with a traditional VCR:"

Ok... What the F... Exactly WHY are they comparing Blu-Ray, a brand new, not even ready technology to VHS which is what? a 25+? 30+ Year old technology?

As long as we're doing that, I'm gonna start a poll.

Which system has better graphics?
Vote1: Vote2:
Xbox360 Atari 2600

Let me know please. I was wondering if Xbox 360 is good enough to finally replace my Atari 2600. Thx to Blu-Ray for the idea.

[truGamer]

I think Atari 2600 lol

[Diamond]

You sure? Thanks. I'm sticking with my Atari.
