Hi,
I'm confused about something. Why is it that in magazines and videos it seems as though adding more transistors to a CPU will make it faster? Is it a numbers thing (like, instead of marking amps on signs, they show volts)? I mean, I understand that you can do multithreading, multiple...
Hi! I am new here and I have come to feed and develop my curiosity in mathematics and sciences. School is not enough I guess...
The ALU is the part of the CPU in which every instruction is executed, right?
But I don't understand, the OS itself is a software in machine language, it is...
Hi All,
I have done a lot of searching and it seems like a lot of people ask this same question but no real answers. I'm wanting to create an app that reads the cpu temp constantly. I want to create this in a windows form gui, but since this information is so scarce i'll settle for a console...
Hi
I'm a layman so please keep your reply as simple as possible. Thanks.
They say that a CPU has built-in circuitry to do simple arithmetic operations such as addition, subtraction, etc. and logical operation such as greater than, less than, etc. I don't understand how could some...
A micro-instruction sequencing and execution machine has a clock cycle
time of 10 ns and a base Cycle Per Instruction (CPI) of 5. The possibility
of interrupts and (or) exceptions may happen in the middle of an
instruction that must have copies of the values of the registers at the
beginning of...
Hey guys... here is the thing.. i kinda blur to talk about the operation..
i need help from u guys to give me ideas to write about the operation..
i attempted the question already.. but, i think it wasn't enough explanations.

I do understand that logical address space/memory is generated by the CPU for the program and physical memory is the one on-to which the logical address space is mapped and which is on the physical memory. Plus, physical memory is not directly accessible to the user.
Now, my question is (I...
Would a single 10GHz CPU be as fast as a quad-core CPU with each core running at 2.5 GHz?
I would imagine that the caches on the Four processor cores would give it a performance advantage over the 10GHz single core.
The way CPU manufacturers went after the days of highly-clocked processors...
What is the fastest GPU setup you can have without encountering any major bottlenecks with an AMD Phenom II X4 965BE? Is it absolutely imperative to have a Core i7 clocked @ 4.0 GHz to properly run the latest graphics cards, especially in SLI/CrossfireX?
My monitor only goes up to a 720p...
Right now, I can only view my CPU temperature in the BIOS menu. I can view my GPU temps in the ATI catalyst control center. I cannot view my CPU temperatures in windows vista home premium 64-bit.
Is there any program I could download which would allow me to view my CPU temperatures in...

I've read that the Radeon HD 5000 series graphics cards, especially the HD 5950, and 5970 dual-core ones, are being bottlenecked by even today's fastest available processors. Including the Core i7 975.
A single Radeon HD 5970 (Two HD 5870 cores) has even more throughput than Two Radeon HD...
I was curious if your OS, and background/system tasks are fully multi-threaded throughout all the Four cores of a quad-core CPU. As well as all Eight threads, if that quad core supports hyper-threading.
Most modern games, like Crysis, are only programmed to be threaded through Two processor...
Because my current graphics card runs burning-hot (past 100 *C) under load, I was hoping of getting a better, and hopefully cooler-running graphics card for Christmas. The overclocking features on my motherboard have been permanently disabled by the manufacturer (Gateway) making any kind of...
Dear Gurus,
I have an old pentium chip covered with thermal paste that is kind of dried and difficult to remove. I intend to clean it with detergent and water.
Would it still work after it is cleaned and dried? That is , is it waterproof?
Thanks for taking time to read my question...
Hi all.
I want to create a Cooler for my CPU to better over-clocking
Because heat has a negative affect on cpu performance and because of my fancy.
I speak about a closed tube that a liquid is injected in it. It should be has a little vacuum, because when the liquid is heated and therefore...
I just installed a new power supply for my desktop last night. In the process I needed to remove the CPU heat sink. With no thermal paste on hand, I just reassembled the heat sink. The question is simply do I need to clean the CPU and reapply thermal paste since the heat sink was unseated?

In a CPU, what exactly is a "cache"?
I was wondering what exactly a "Cache" is in a CPU. Why does having a larger cache improve performance? In the Phenom II and Core i7 processors, I noticed that they have a small amount of L2, and L3 cache, and 8 MB of L4 cache per core. What does this mean...
My old desktop PC which I built circa 2003, has officially stopped working. The parts in it are discontinued and I can't find them to buy anywhere. I am getting a new desktop as a christmas gift. I wanted you to tell me your professional opinion on which processor is better.

The other day, watching to buy a new computer I saw CPU prices, and I asked myself why prices are so high.
I mean, its just a tiny piece of semiconductor.
Does the high price comes from the design of them, or it's that manufacturing them are expensive and machines to work at such small...
The fastest stock clock speed I have ever seen on a CPU the is currently available to the public is the Intel Core 2 Quad 4.0 GHz. (it may be overclocked) For the past few years, clocks on CPU's never seemed to get substantially higher. Is there some kind of thermal limit to how fast you can run...
I'm running Windows XP on a dual-core notebook and I noticed that sometimes (like now ;)) the computer slows down dramatically as though under heavy load, but the task manager reports nothing: the system idle process claims 97% of the CPU and there's only ~500 MB of RAM in use (on a 2 GB...
Hello everybody,
my question is: do you get an increase in speed/power/performance when you "freeze" computer components such as the CPU with LN2 or phase change cooling, getting to under -100º,-150º.
Because as long as I'm aware CPU´s are made out of semiconductors and as temp lowers the...
I am interested in CPU design as well as computer hardware design. However, I could find very little information on CPU design. I was wondering what the best major would be, the salary, and any other information regarding this topic.
Advice would be greatly appreciated.

My CPU temperature is high at 91°C or more after 5 minutes of working.
The limits of threshold is 90°C and highest temperature is shown to be 100°C.

Please advice how to proceed!
Thank you!
So I know that my CPU is now slowing down, even though Process Explorer reports system usage as varying between 30-70%, far short of 100% system usage. What is the most reliable way to measure system usage before the system starts to slow down?
