Can't wait to see more of the PowerBook?

Head down to suyama-san's great site: http://suyama.co.jp/

As you can see, the 12" is an iBook actually no matter want they want to call it... ^^

At least they moved the AC port to the left side with all the other ports. That makes docking easier.

But how can they call it a "full feature" notebook when it does NOT have a PC card slot? Ha!

640MB RAM max is pretty low, too. It doesn't seem to have any L3 cache either.

It is an soup-up iBook. It's... it's... CHEATING!

perhaps we should call it "iBook G4"?

so ... the "iBook G4" uses GeForce 4 Go MX 420 ...

how about the 17" TiBook?

有誰知道嗎?謝謝 ...

if you can find the specs of the 12" iBook g4... then you should also know the 17" giant uses GeForce4 440 Go/64M DDR.

speed wise for GPU (if I remember right)

ATI RM7500 > GeForce4 420 Go > ATI RM9000 > GeForce4 440 Go

GeForce4 has higher power consumption than ATI's (correct me if I'm wrong)

查到了... 是 Go 440 ...

Apple 合時才會用 Go 460 呢?

P/S : 多謝 oeyvind 的回應 (小弟慢一步 send 了 )

更正，該是420 Go > 440 Go > RM7500 > RM9000。
引用自Tom's Hardware Guide。
Power Saving就更是420 Go > 440 Go > RM7500 > RM9000！
顏色上Nvidia Cards更不用說了，Steve Jobs為何選中GeForce？

Anyway PB G4 makes a great UNIX machine anytime:

Me fooling around with Apple X11

但這也不盡然,
因為Tom's的評比是在PC NB上的表現,
Mac OS X可不支援DirectX阿!
所以話也別說的太滿,
再看看表現吧...

除非 ATI 有 Radeon Mobility 9700 囉 ...

小弟真是妄想!

Me fully around with Apple X11

For one not really relative question:
Is there any problem or issue we have to pay attention to during installing X11 package from Apple while Xfree86 4.2 installed already?

Thanks

如果說DirectX的result不能作準的話，唯一理由是ATI的DirectX driver比nVidia好，而ATI的Quartz/QuickTime driver又比nVidia的差。但這不是事實。
ATI的Windows driver不及nVidia已是人所共知的，至於在OS X上的driver+hardware比較，可以參考Mac's Only的報告。雖然不是MR9K比GF4go440，但明顯地，ATI在Mac platform上，比nVidia更有利。

如果要solid proof的話，要等有人post新PowerBook 17"的Result上網再作比較。

小弟後來再找找資料,
我還是只能確定MR9K是最好的選擇,
後面的排名就不確定了

雖然心中有點遺憾,
可是最遺憾的是12"PB沒有L3 cache跟ambient light sensor!!!
前者在速度上不知道會影響多少,
後者讓我失去在暗暗的會議室或房間中可以方便使用的機會...

在15" PowerBook 1G上，L3 Cache在大多數的程式上大約會打七折，12" PowerBook上應該影響少些，一來867是6.5x system bus，比1G的7.5x低，二來867有DDR RAM。

請參考香港rhapsody的討論。

不過，有些特別的軟件，如VPC，沒有L3的話，只有兩成速度！

哈哈。那個蘋果才有的DDR/2（除以二）會有多大幫助？

mmm...都有少少作用的，一來DDR的chip，一般比SDR的快，可以省到一個或半個cycle輸出critical word，相當於867的6/3 CPU cycles或1G的7/3 CPU cycles。
二來，DDR可以令FSB和AGP更飽和，十個bubbles中，減少一兩個也是好的。

不過DDR SODIMM可貴多了！
