著名微软员工博客Ozymandias近日针对Sony新一代游戏主机PlayStation 3进行了有力的抨击－－靶子则为PS3引以为豪的蓝光光驱。

Ozymandias表示，在游戏加载速度上，Xbox 360要远远高于PS3－－或者说，PS3将非常慢。原因？

Xbox 360采用12X DVD光驱，能够提供16MB/s数据传输速度，相比之下，Sony仅给PS3配备了2X蓝光光驱，数据传输速度仅有－－9MB/s。

除此之外，你还要考虑到PS3游戏的超大容量，很容易达到Xbox 360的数倍－－例如，已经达到22GB的《Resistance: Fall of Man》。

PS3游戏加载所需要的时间，你可以想象得出来。

ＳＯＮＹ：ＰＳ３为什么用蓝光？

针对微软员工对PS3游戏加载速度的抨击，著名Sony游戏开发人员Mark Deloura分享了自己的观点，有趣的是，Mark Deloura并未正面回答微软方面有关游戏加载速度的指责，而是换了一个角度，告诉我们－－蓝光对新一代游戏有多么重要。

1.PS3游戏中贴图纹理质量相对上一带提升至16X－－甚至能够把纹理数据容量推到32GB以上
2.PS2游戏绝大多数音轨为双声道，PS3游戏音轨则为5.1声道－－音频文件容量至少提升3倍
3.标准视频格式从480i提升到720p－－达到1280×720@60fps，每秒5520万象素，容量达到480p的6倍

在备受怀疑的光驱方面，Mark Deloura的回答竟不啻于“附和”微软的指责：

“必需要承认，在非容量因素上，蓝光技术目前确实存在不少不确定性－－蓝光电影需要1.5X蓝光光驱支持（54Mbps），PS3的蓝光光驱则为2X（72Mbps＝9MB/s）－－小于Xbox 360 12X DVD光驱的16MB/s，而且Xbox 360的DVD光驱成本要低得多。”

消费者们，你们如何选择？

惊到了，楼主竟然发了正面帖

不是正面贴

这叫欲擒故纵。没看到有个固然么？

一个消息发两贴。

何况本来就火星了。

说明一下， DeLoura就是从索尼跳槽到Ubisoft的那位。微软的 Vrignaud 和他是好友。Vrignaud在论坛上贴了篇文，结果两人在各自的Blog上“战”起来了——当然他们达成了“粗暴的和解”

September 1, 2006

Opinion: Microsoft's Vrignaud, UbiSoft's DeLoura on Blu-ray

Opinion: Microsoft's Vrignaud, UbiSoft's DeLoura on Blu-ray Xbox strategy group member and outspoken blogger Andre Vrignaud has responded to a recent open dialogue with former Sony Development head and current technical director for Ubisoft, Mark DeLoura, regarding Sony's Blu-ray support with PS3, concluding, to his surprise, that the two are in "violent agreement."

Vrignaud kicked off the debate with two earlier posts on his Ozymandias blog, citing Sony claims that the Blu-ray's increased storage capacity were essential for its inclusion in its next generation hardware. On the contrary, said Vrignaud, it was drive speed that should be the deciding factor, and there, he concluded, the Blu-ray might fall short:

"At GDC Europe last year Sony mentioned in their presentation that the PS3 Blu-ray drive would have sustained peak transfer rates of 36 MBit/s (4.5 MB/s) at 1x speed. Since then it appears that the drive has been upgraded to a 2x drive, which would enable transfer rates of 9 MB/s. Assuming a full 50 GB Blu-ray disc, at this speed you'd need just over 90 minutes to read the entire disc through memory. Of course, you can't fit all of that data into system memory at the same time, so you'll either be streaming a great deal (hard even with faster optical drives) and/or caching data to the hard drive. There's a reason the PS3 is so expensive - once Sony committed to Blu-ray as a corporate strategy, they were also forced to bundle the hard drive in every box to help mitigate slow disc data transfer rates. PS3 games need that hard drive to load in any reasonable time - just look at the PSP for an example of the effects of a slow optical drive on game loading times."

The post prompted a fast response from DeLoura, adding a litany of reasons why capacity was indeed a deciding factor:

"Audio on PS2 was mostly stereo, two channels. PS3 is 5.1. That's a 3x size increase without even considering fidelity.

Default video format has moved from 480i, or roughly 640x480 at 30 frames per second (9.2 million pixels per second), to 720p. 720p is 1280x720 at 60 frames per second (55.3 million pixels per second). That's about a 6x size increase. 6 x 2GB would again push us over the DVD-9 size."

In his most recent post, Vrignaud takes issue with those claims, mentioning the Xbox's already standing 5.1 audio and increased processing power offsetting the cost of video resolution with more powerful compression schemes.

But it's on the subject of format throughput and marketing demand that the two were able to find some common ground.

DeLoura does concede that the Xbox 360's 12x DVD, which reads at 16MB/second, gives it a clear speed advantage over the PS3's 2x BD drive at 9MB/second, making for significantly faster load times in games, as well as a much cheaper component price for Microsoft. But that point doesn't necessary dissuade him entirely from Sony's BD strategy.

Instead, he points out that high numbers of PS2 early adoption could be taken as a result of its double-duty as an inexpensive DVD player, which could also similarly drive early PS3 sales as an inexpensive BD player, despite its increased cost as a console:

"Blu-Ray drives and discs have been very sparse so marketplace awareness is slight - it is more accurate to compare against the BD launches of 2006, which would make Blu-Ray for PS3 significantly earlier in the marketplace than was DVD for PS2.

The result is that the Blu-Ray drives for PS3 are expensive, and the demand for Blu-Ray movies in the marketplace has not flowered open yet. PS3 could stoke that fire, but it doesn't seem likely that Blu-Ray will significantly drive sales of the PS3 beyond a small hardcore market, in the short term.

It seems the decision to include Blu-Ray on PS3 must have been a difficult one. Long term it seems like a smart move, at least from the perspective of capacity. But short term that decision has definitely had some striking ramifications for PS3."

In response, Vrignaud summarizes:

"We seem to generally agree from across the (former) divide. Blu-ray as a system driver would be a lot more effective if there wasn't this whole format war thing going on. Until that's satisfactorily resolved (or dual-format players come on the market), consumers are just going to hold off. From my perspective it doesn't really matter as I'll have both a PS3 and an Xbox 360 HD-DVD drive the day they come out. But people with families to support or less disposable income are going to be deciding their PS3 purchase decision based on the system's merits as a game player, not a movie player."

现在这么说有用么

“必需要承认，在非容量因素上，蓝光技术目前确实存在不少不确定性－－蓝光电影需要1.5X蓝光光驱支持（54Mbps），PS3的蓝光光驱则为2X （72Mbps＝9MB/s）－－小于Xbox 360 12X DVD光驱的16MB/s，而且Xbox 360的DVD光驱成本要低得多。”

看实际效果

无语～果然微软都是软饭们开的，连M$找了一个低成本的旧世代的东西的东西都好意思拿来炫耀～

等技术成熟再买

别象ＳＮＫ的武士道列传那样开一次门要等好长时间，那样的话那可就太操蛋了。
