I have Core 2 Duo with speed P9800 2.9Ghz Speed.
I have a plan to change my laptop to the new Z series with i7 620M @ 2.66Mhz with speed up to 3Ghz.
Will it be any obvious speed improvement?
Anyone know the any link on the website which have information of their benchmark?
Does anyone know what the speed is of the iLink port on the new Sony Vaio Z Series Core I7?
I'm trying to decide whether to get the Vaio Z with 3 usb ports or 2 usb ports and 1 iLink port. If the iLink port is a lot faster then the usb ports i'll probably get it with an ilink port. If it's a slow ilink port (400 mbps) then i'll probably get the laptop with 3 usb ports.
It would be nice if it comes with a fast ilink port (800mbps) so i can get a faster connection if i connect the laptop to an external hard drive.
Model: Lenovo z50-75
AMD Vision A8-7100 Processor ,max 3,0 GHz, Â Quad-Core

Took this from an Notebook review on Notebookcheck(dot)net:
Â
"It is comprised of the integrated Radeon R5 Kaveri graphics core and the dedicated Radeon R5 M230 GPU. The GPUs operate in a so-called Crossfire array, i.e. both cores can perform the calculation of displayed images. This process is, for example, used in computer games. Only the integrated GPU is used for routine tasks and in battery mode"
Â
i've managed to finally install Windows on the Laptop.
Â
But unfortunately he's pretty slow, even with the 4GB added memory.
Â
When i bought it, it was said it had 4x 1,8Ghz CPU speed which could go on up to 3Ghz.
Also this dual Graphics solution is somewhy worse than the desktop Computers is, even though the Desktop computer has way worse components. It's said that the normal usage of the computer only requires the graphic processors of the GPU. however there is a graphic card with dedicated memory which should be activated whenever requirement on higher performance applications / games is needed.
I bought the Acer 1410 with the single core SU3500 Core 2 Solo CPU. It looks like Acer decided to release them with the SU2300 now, which is dual core at 1.2GHz (compared with 1.4GHz of SU3500).
Does anyone have any benchmarks comparing the two, and/or if they have a solid understanding how much better it would perform compared with the SU3500? I also see that the single core AS1410 with Celeron M @ 1.3GHz sells at the same price as the dual core.

upgrading my Aspire 5570 notebook more than a year ago. This time, I’m feeling lucky to share some of my experiences about how I finally upgraded my CPU from a Core Solo T1350Core 2 Duo T7200.
Again, thanks to everybody here in Notebookreview forum especially adinu, hoggie, Mack1982, TehSuigi, krazyphire and bigozone for their insights and knowledge that helps me a lot throughout the whole process. So, let’s get started!
Pre-upgrading
Please refer to these post before you start. It'll save you a lot of time and trouble later on.
Upgraded Acer 3680 Celeron CPU to a T5300!
Aspire 5315 CPU Step-by-Step Upgrade Guide
What you’ll need :Your new CPU (make sure it's compatible with your system ie; socket, FSB)Latest BIOS from Acer (upgraded to 1.3505 or latest)A good thermal paste (I would recommend Tuniq TX-2 or Arctic Silver 5 as well)Basic tools (screwdrivers, forceps, kitchen paper)Body static discharger (I would definitely recommend this as a precaution)Some alcohol, ear buds, sand paper grid 600,1200 & 2000 (optional for heat sink lapping)Lastly TIME and PATIENCE (you’ll be needing these a lot definitely!)When you’re ready, lets get our hands dirty.
How to disassemble your notebook?
I found out a very good video tutorial on how to disassemble my Aspire notebook on YouTube. So please take your time to view it and follow step by step as shown to help you to go through the process.
Lapping your heat sink (optional)
Although it’s not necessary, but I would recommend this process as another way to improve heat dissipation on your newly installed CPU. Refer to this page for detailed instructions.
The simple process:Clean your heat sink from old thermal paste residues with alcohol or equivalent of it using ear buds and kitchen papers.Apply a 600-grid sandpaper to smoothen the heat sink surface which comes into contact with your CPU.Repeat the process again with a 1200-gid sand paper until you’re satisfied.Finally, finish up by applying a 2000-grid sand paper to give you an almost mirror-finished surface. Wipe clean any dirt and residues left.....................................
I will be buying a new laptop to replace my Acer Aspire 5738G.
I am considering HP Dv8t Quad Core i7 or HP Probook 4720s.
I am a web developer and I some time use my laptop continuously for 2-3 days.
choosing between these 2 laptops, which one will be better for me?
I bought the i7-3520M (dual) and I looked in the manual to see what slots to use for my memory upgrade and the instructions were completely off (where the dummy stick is supposed to be and where it actually was).
Â
I purchased two 8GB (Kingston) sticks to replace the 4GB that came installed. I took out the original 4GB under the keyboard and replaced it with the new 8GB Kingston. Everything worked great and I've been using it that way for about a week.
Â
Tonight I decided to go ahead and install the other 8GB. I assumed it would go in the bottom slot where there's a dummy stick. I pulled out the dummy and placed my 8GB there. Turned the laptop on and... nothing. It wouldn't power on at all. I took my 8GB out and put the dummy back and it worked fine. Just to make sure I didn't get a bad stick, I replaced the one under the keyboard with my other 8GB and it worked fine there. My question is where is my second 8GB supposed to be installed and does that one dummy stick always stay where it is? It does have a "do not remove" graphic on it, but I thought it was only because the laptop came with one stick and if you were putting two in you would replace it.
I want to upgrade my old laptop to something nice, and am torn between to systems.
An HDX 16 with:
2.40 Ghz dual core duo ( P8600 chip )
6 gigs of ram
OR...
An HXD 18 with
2.0 Ghz QUAD core ( QX9000 chip )
4 gigs of ram
both systems have the same video card ( Nvidia with 512megs of ram ) 500 gig hard drive.
What would be the faster machine for doing video ? and what would be the overall faster machine ?
I realize that not all applications will take advantage of a quad-core chip like the QX900, so this is why I"m asking. if the dual-core P8600 chip @ 2.40 Ghz in the HP HDX 16 with that 6 gigs of ram will actually be faster overall than the quad core would be, and perhaps even be faster at rendering video ?
I bought a ThinkPad X240 recently.  On Lenovo's website, it says the max speed is 3.30 GHz.  However, in the Windows 8.1 Task Manager, it says the maximum speed is 2.69 GHz.  See [URL] ....
Â
Why there is a discrepancy? Â I also tried running Prime 95 for a little while and noticed that the "Speed" in Task Manager never went above 2.70 GHz. Â Did I somehow get a weird i7-4600U processor that has a max speed of only 2.7 GHz?
I had purchased lenovo g580 core i3 a year ago. 2 days ago, after shutting my laptop, when i tried to switch on, usual lenovo screen appeared in the beginning, but does not happen anything after that. it hangs there, without giving any response.. there are 2 option i.e., to press F2 for setup and F12 for boot menu. but nothing happens even when i press those buttons...

the 2700 has 2.33 ghz but only 2 meg cache.. the 7400 has 2.16 ghz but 4 meg chache...
or should i keep my 7200....
Really looking forward to those. I think that's when I'll upgrade my SZ680. I was really not happy with it until I installed Windows 7. Now, it's good enough until the Core i7's come out.

First things first: The new Z is the best laptop I've owned so far. End of story. Had MBP, MBA, AW m15x and several Dells, but nothing like this.
Second:
Im not a big fan of hardware overclocking/undervolting (anymore). (Referring to the "Insyde hacking" thread.)
Ok, with that in mind; how do I software undervolt the mobile core i7 processor?
Tried good old RMClock, which doesn't work. (It hasn't been updated for years, so I didn't expect it to).
CPUgenie... didn't work.
Crystal CPUID.. didn't work.
Now I'm out of own ideas, started searching. The only thing related to my "problem" (which actually isn't a problem, I'm just a big fan of undervolting and want it that way), is this thread:
ThrottleStop thread here on NBR.
Downloaded it, tried it... doesn't work. I don't get access to the voltages.
i want to buy a HD PVR but my laptop doesnt meet the system requirements needed, all i want to do is record it on my laptop and than transfer the files to my desktop pc so no editing or any other software will be needed on my laptop
heres the laptop i own

and heres the HD PVR system requirements
Hauppauge Computer Works Ltd : HD PVR
I just cancelled an order with Dell for a Studio 1747 (it was taking too long - 2 months from order date, and yet they charged my credit card the day after I placed the order, which I wasn't pleased about), so this lead me to searching for another laptop and I came accross the subject of the post.
I quite liked the look of the first CW (Core 2, compact with a decent GPU), but wanted a newer architecture machine with a higher res panel (for dev work), but on cancellation I started searching around and found this on Sony's site (UK):
[url]
Under configurable models. It defaults to the i3, with GeForce G310, 2Gb RAM and 1366x768 panel but you can spec it up with:
i5 520
1600x900 Panel (this option also boosts the graphics to a GT330 512Mb)
Along with the usual RAM and HDD upgrades.
I'd prefer a quad core (I actually use it in both dev and day to day work) and full HD (but that's just not realistic for a screen this size - this is the first time I've seen anything this high res on a 14" screen); but this is just too tempting in a small package (no more broken back on the train lugging my Dell XPS M1710!!!), with a pretty decent spec, and I'd figure the performance is going to be rather good anyhow. I'm looking at this config which is showing up as £849 and strikes me as pretty good value:
Your configuration
Processor: Intel® CoreTM i5 Processor

Hard drive: 320 GB Serial ATA (5400 rpm)..........
I have a quad core Lenovo W520 (i7-2820QM) equipped with Intel AMT. I have all RAM slots populated (original 2GB in each that came with the machine). I have updated to the latest BIOS (1.42 at the time of writing) and latest Intel Management Engine Firmware 7.1 (7.1.85.1216 at the time of writing). The machine has Crucial 256GB X100 SSD installed in the main compartment and a regular HDD in UltraBay.
Â
The computer acts normally in sleep mode and restart sequence only when Intel AMT states that "ME is in recovery state..." during boot.
Â
When it looks like AMT is happy problems begin. The problem is that when I'm trying to put the computer to sleep it goes all the way until the end per normal procedure and then suddenly decides to power itself off! Obviously Windows doesn't like this and displays recovery suggestions after starting the laptop again. This happens when connected to AC and also when disconnected from it. Also, when computer reboots it turns off all power (i.e. the display along with backlight, indicator LEDs turn off and fans spin down for a sec) inbetween and automatically starts up after that.
Â
I've tested this on Windows 7 and openSUSE 13.1 (which I had lying nearby) and same behavior happens on both OSes. On Windows, all the latest drivers and updates were installed. So I don't think this is driver nor OS dependent - rather firmware/hardware related problem.
Â
What is funny, it doesn't matter whether Intel AMT is activated in BIOS or not. What matters is whether the Management Engine is in some kind of recovery state or not. When it's not, computer starts acting crazy as stated above and behaviour is repeatable. Intel AMT itself seems to work however. Changing the power policy in Intel ME configuration doesn't work for sleep issue.
Â
Some things I've also tried doing:
* Replace CMOS battery (measured its voltage before putting it in, of course) with a new one - no effect
* Tried two different brands of SSDs (OCZ Vertex 3 and Crucial X100) - no effect
* Tried both legacy and UEFI modes - no effect
* Scanned RAM for memory errors - no effect
Â
Could Lenovo try to repeat this issue and possibly do something about this?
Here it is the new Z (no pics yet):

* Windows 7 Home Premium

The review of Laptop Magazine has comparison of the new MacBook Pro Core i7 and Sony Z11. It sounds like that the new MBP wins Sony Z11 in many places except the hard disk drive performance. Engadget published one also.

What do you think?
Since Intel has released it's latest mobile CPU's, can we expect any new Sony models?
[url]
I would hope that Sony will consider a refresh with both the new Core I7 mobile cpu and a higher end video card. The competition is already lining up with just these items.
View 10 Replies View RelatedI was all set to order my CTO Z with Core i7 on sonystyle but it seems that it won't allow me to select the Core i7 unless I also add the $100 Verizon mobile broadband. This seems quite odd as I don't have any interest in the mobile broadband but do want the faster processor. Any way to get around this? I don't want any of the pre-configured models as there are other things I want to tweak.

YouTube - 2.4 GHz Core i5 or Core i7 2.66 GHz MacBook Pro? i5 vs i7 Benchmarks & Which one you should get!
I am considering a range of Vaios at the moment (including some HP models; although Vaios are my #1 choice).
With the new Core i7 Processors out, I am wondering whether buying a Core 2 Duo processor of any sort (TT: SU; Z & SR: P9xxx, etc) now would mean they would be totally redundant by Q1 of 2010 or do you see some variants of the Core 2 Duo processor lasting a bit longer?
I realise technology continues to move forward at a rapid pace and was just curious about where Core 2 Duo stands in Q1 of next year.
what the performance difference is between the Intel Core i7-620M and the . Intel Core i7-820QM. I always thought the quad core 820QM was faster, but on the hp website the dual core 620M is more expensive.
Is the 620M faster? And is it faster for specific things only?
