intel-core-i5 interview questions
Top intel-core-i5 frequently asked interview questions
I'm buying a laptop for $849.99 and it purports that the i5-450m chip "turbo boosts" up to 2.66ghz, 4 threads, and 3m cache. Is this an idealized claim, or will it actually dramatically improve performance? Also, do I have to do something special to use turbo boost? Are there power/heat/battery life concerns?

I'm curious about the new innovations in Intel's Core i5 and i7 series of chips, in particular the Turbo Boost Technology. (Doesn't turbo boost remind you of Knight Rider?)
What are the details on how it works? Is it a marketing gimmick or are there some serious and impressive performance numbers behind Turbo Boost Technology?
Are we likely to need better power supplies and even bigger heat sinks and fans with these new chips?

I'm planning on getting a custom desktop PC assembled.
I had planned on an Intel i5-2400 (Sandy bridge) processor in tandem with an Asus p8h67mle motherboard.
After Intel's admission of a manufacturing defect affecting the Sandy Bridge platform, should I be concerned even though I have an Intel processor but a non-Intel motherboard?
Is the problem part of the processor or a chipset on the motherboard?
Which of these components is safe to keep and use?

I have a laptop with Intel i5 M430 2.27GHz.
The CPU has TWO REAL cores but it also has some kind of virtualization so Windows sees it as 4-core.
In a REAL dual core CPU, a single threaded program will run in a single core at 2.27GHz. Right?
My question is, in my 4-core CPU, the same program runs at a speed of 1.13 GHz? (2.27 / 2)
I mean, the frequency of each real core is split in two in order to simulate a 4-core CPU?
I need to know for to run a CPU-hungry program at maximum speed. If I run two instances of that program I will finish my data processing two times faster, because I have two real cores. But if I start 4 instances I will finish the processing 4 times faster or is this '2 extra virtual cores' thingy another eye-candy feature from Intel?
Update:
I used CPU Overload to start 2 and 3 very CPU intensive threads. In Resource Monitor the "CPU-Total" graph shows only 50 and respectively 75% utilization.

I'm recommending a laptop to a colleague, and the specific laptop he has chosen has the above CPU chips as options. Both chips have 2-cores/4-threads. The i7-620M is a 2.66 GHz (4MB Cache) while the i5-540M is a 2.53 GHz (3MB Cache)....both Arrandale architecture.
He is a .NET programmer working with SQL Server and Oracle, and occasionally uses Adobe Fireworks for web-related design elements. He also loves playing around in Adobe Premiere Pro, and does a lot of media/video work.
Would you notice any significant performance difference between the 2? The laptop manufacturer claims that the battery life on both is the same irrespective of the chip used (although I find that hard to believe), but there is a major cost difference between them, with the Core i7-620M being the more expensive.
According to http://ark.intel.com, the one thing that seems different (besides the obvious speeds/frequencies/etc) is a feature called "Embedded" - what is this exactly? You can see the quick comparison here -> http://ark.intel.com/Compare.aspx?ids=43544,43560
I would sincerely appreciate any advice me on this. THANKS!

Does changing the number of processors under Boot Advanced Options affect computer speed?
I have Dell XPS 15z Windows 7 Home Premium (64 bit) OS with 4GB RAM, intel i5 processor @2.5 Ghz and 1GB nVidia Graphics.By default, it uses 4 cpu however my system is slow in booting up and seems lazy doing simple things like opening programs and files, i mean the response is slow.
However, when I reduced the number of process to 2 or 3 or 1, the boot up time reduced significantly and system responded quick to any actions but there was lag as it was clear with gaming.
I don't know what to do.....it's so embarassing to have high performance gaming computer but still sucks at doing normal operations especially booting up - it takes more than 4 minutes!
I have very few programs to run at start up.
Any suggestions to improve the speed of my system?

I've just finished building a new computer with one of those new-fangled Haswell CPUs; in particular, the Intel Core i5-4570.
I plug in the power, turn it on, and watch as everything starts spinning up right away... except the stock CPU cooler fan. Instead, in the first 5 seconds or so the CPU cooler fan simply twitches a couple of times, after which it starts up with a loud whir for 2 or 3 seconds, before spinning down to normal speed and quietness.
Being a first-time PC builder, naturally I got worried that something had gone horribly wrong with my CPU cooler, especially seeing how the fan blades were twitching in the first few seconds. But apparently, this is normal, and something that many motherboards (including my ASRock H87M Pro4) do by default as part of their fan control procedures, so I'll assume that it's safe. I'm not overclocking anyway.
But what's the purpose of this behavior? Why doesn't the CPU cooler just spin up normally like all the other fans (case, GPU and PSU)? Also, if I can change it so that the CPU cooler fan does spin up normally, should I do that or is it better to leave it as it is with this seemingly unusual behavior?

I am considering the purchase of some software (AutoCAD) that requires the CPU to support SSE2.
My PC's CPU is an Intel® Core™ i5-650 Processor, which supports SSE4.2.
Basically what I am wondering is whether SSE4.2 is simply a newer version of SSE2, and if so are newer versions of SSE backwards compatible?

The Intel Core i7 has a Hyper Threading feature.
How is this feature helpful when it comes to software development? (Not game development)

Does anyone know how to get the temperature of an Intel Core i5 processor in FreeBSD?
Relevant info:
- Motherboard: Asus P8P67 Deluxe
- CPU: Intel(R) Core(TM) i5-2500
- OS: FreeBSD 8.2-RELEASE (64bit)
I've tried:
sysctl -a ⇒ nothing about CPU-temp therembmon ⇒ outputs: No Hardware Monitor found!! InitMBInfo: Unknown error: 0
I've successfully used mbmon on previous rigs with older hardware, but I can't get it to work with this setup. I've tried all "access methods" (options -V, -S, -I, -A).

My laptop's CPU fan is suddenly acting very bizarre, and I am at a loss for what to do so I am asking for some help.
Specifically, the fan is not even starting to spin until the CPU reaches 60 degrees Celsius (checked through HWmonitor). Once it is on, however, it properly stays on even when the CPU gets back to idle temps around 38 Celsius. Before, the fan was simply starting with the computer and staying on like normal.
I've checked this for consistency both by allowing cold boots to ramp up temperature to 60 Celsius (the slow climb also causing the laptop to become unreasonably warm near the heatsink), and also running Prime95 immediately to kickstart the fan (this works every time).
The fan seems to be stationary when turning the computer on from either sleep or shutdown. The fan will start at POST very briefly, and then stop completely. I've checked the BIOS for a SmartFan setting but haven't found any.
I've opened the case to check for dust or debris and have not found anything (I applied some canned air to the area just in case). The laptop is a Lenovo ThinkPad Edge E430 and the CPU is an Intel Core i5 3210m @ 2.5 GHz.
Any advice would really be appreciated.

I recently purchased a laptop with an i7-640m processor (blinded by a discount), and my battery life is fairly horrendous: the manufacturer given battery life is 6 hours (I know, it's an upper bound), and I barely squeeze out 3 hours with light usage+wifi. I can't seem to find any information on whether swapping out the processor for a i5 or even an i3 would significantly extend the battery life, aside from people baldly asserting "it should extend battery life" and my own intuition.
Has anyone tried to quantitatively compare these processor families with respect to battery life?
Note that the upper-bound on the battery life was probably with the default i5 configuration, and that my laptop heats up very quickly and stays hot, possibly pointing to more power dissipation than the laptop was designed to handle. I should also note that Engadget gets around 5.5 hours with a similar usage profile, for a i5 configuration. The TDP is exactly the same for all three (i3-3xxm, i5-5xxm, i7-6xxm)

I'm choosing a new laptop and one of the questions is a type of CPU — mobile or ultra-low voltage. If to be more precise, I'm torn between two models of Intel Core i5 — i5-2410M (Sandy Bridge) and i5-3317U (Ivy Bridge). Here is a comparison table of these models.
According to official specs the first one has 2.3 GHz clock speed while the second one has only 1.7 GHz, that's about 25% difference. Is it really important parameter and which CPU is preferable for a laptop for development, running VMware virtual machine, media and internet purposes?

I am looking for a new laptop and the two i am deciding between is an Asus with Intel® Core™ i5-430M processor and NVIDIA GeForce GTS 360M graphics. Or a Toshiba with the Intel® Core™ i7-720QM processor and NVIDIA GeForce 310M graphics.
Other than that both are the same with 16" screen but the Toshiba has the 500GB Serial ATA hard drive (5400 rpm) and the Asus has the 500GB Serial ATA hard drive (7200 rpm).
I am looking for a computer to use for college and be able to play games on. I want to know what one I should get they are both the same price.
