I did share - I showed you exactly why your reasoning is wrong. Sounds like you need to continue your schooling, as you don't understand basic principles of electrical engineering.
Do you understand what TDP is?
http://en.wikipedia.org/wiki/Thermal_Design_Power
It's a measure of required MAXIMUM cooling efficiency for a hardware design. Just because a CPU is rated at a certain TDP (as is quite common with different clock speeds of CPUs from the same family, process technology, etc), does NOT mean that the particular chip you are using consumes anywhere near that level. Two identical chips running different clock speeds will NOT be consuming the same amount of power in real-time.
If you think otherwise, I'd march into your dean's office and demand a refund, as your educational institution has failed you.
So all models except the 17" have this 'feature'?. I currently have a prev model 2.66 next to me and was actually considering turning it in for the newer 2.66 due to its superior screen/batt but i'm starting to think maybe i should hold on to it now. As its stands...upgrading to the newer 2.66 means you lose half the L2 Cache, half the VRAM, half the SATA bus speed.
I mean SSDs are the future and what if i decide to upgrade to one...it'll be disconcerting to spend that money and not have 100% saturation

I've decided (it's been confirmed) that now only the 17" and SSD-configured MBP's support 3 Gbits.
I might as well hold on to my 1st gen 15".
TDP measures _nothing_ related to real-time power consumption. It's a technical specification as related to a hardware design and associated cooling system. TDP does NOT "measure how much power the cpu will consume independent of clock". You are, quite simply, flat-out wrong.
Listen to what you're saying for a minute. You're saying that regardless of clock speed, be it 100MHz or 3GHz, that chip will consume 17W of power. Do you have any idea how ludicrous that sounds? Seriously, go ask your professor before you graduate. Time is of the essence. Do you understand how transistors work? You apply a voltage (ie power) to open or close the gate. The more times you open or close a gate per second (ie clock speed), the more power you consume, all other things being equal.
How do you "cap" a serial bus at a certain speed without lowering the clock speed (and therefore power consumption)? Keep everything the same but only allow a data transmission on every other cycle? That's one solution, but not one that any hardware engineer worth his weight in manure would consider.
I'm sorry you don't understand the fundamental basics of chip design and power consumption, but that's no reason to spread a bunch of blatant misinformation to a forum full of people who don't know better.
Wait...you mean if you configure your MBP with an SSD when buying. Apple lift's the cap?
Where has it been confirmed? The MBPs with SSDs haven't even started shipping yet.
I would be really pissed off had I bought this new machine only to find out Apple did what Lenovo did on their Thinkpads
I was going to sell my 15" Macbook Pro that I had bought 2 months ago but now that I know the new ones only support 1.5 Gbps like the new Thinkpads from Lenovo, I think I will keep my current one. Apple just lost a new sell from me.
So I've heard earlier in this thread. He apparently phoned Apple and confirmed whether his new 13" would support 3, or he would have cancelled his order.
I'm at the Apple store right now and the 15" 2.66 definitely has a 1.5Gb controller. I asked the genius and they said that they SSD will be bottlenecked.
Anyone know if the new Macbooks which were shipped last month with the new screens offer 3.0 Gbps Sata?
Is there a way to block this idiots posts, so I don't even have to read his nonsense? Dude sounds just like Virgil-TB2 from Appleinsider, a completely brainwashed sheep.
Anyways here is mine:
13" 2.26GHz MBP
128GB Corsair SSD

Sorry, I don't know how I completely missed that post.
Couldn't you have just stated that in the first place?
Let's not forget the new 13" MacBook Pro has the exact same controller as the previous 13" MacBook and is fully capable of 3.0. Apple has just done something in software/firmware to cap this to 1.5. It has been suggested that if you order one with an SSD from Apple they "flip the switch" so to speak and allow 3.0. I guess that means firmware not software then. It has also been suggested that the only retail model to have 3.0 is the 17" version. We don't know if this is true yet but the evidence is mounting. I will add that when I called my local Apple Store they mentioned the price cuts as the reason for this. That makes no sense whatsoever of course as crippling firmware does not save any money.
Funny how Apple always brags about improvements in speed but when they stick you with something slower like a slower Sata at 1.5 Gbps they they never mention it
Jesus H. Christ.
Apple did this so the mechanically inclined/tinkerer won't go open up their machines and update them with SSDs, after purchasing the cheaper hard drive model. What a friggin' sham. SSDs are expensive enough on their own without applying the Apple Tax to them.
So everyone out there who was planning on buying the base 13" MBP to later upgrade the memory and swap the hard drive with a nice speedy SSD variant, Apple just screwed you.

Wait, wait, wait.
Can somebody translate all of this tech-talk into layman's terms?
I'm quite new to all of this, and want to make a smart, educated choice when purchasing a 13" this coming Monday (or not, if 1.5 SATA is really that bad).
Simple answer:
Unless you plan on purchasing one of the few SSDs on the market right now that can provide sustained transfer rates greater than 150MB/sec, you will notice absolutely no - zero, zilch, nada - difference. Except maybe a possible increase in battery life over a similarly-equipped machine with a 3.0Gbps bus.
Given all the articles floating around about how the new systems' battery life is markedly better than it should be based on just the battery improvements alone, this would not surprise me in the least.
