Proccessors and what makes them good?

Question

Many questions a'wait your answering :)--


1. If a processor is advertised at having a 3.0ghz speed and 4 cores, does each core get 3.0 or is it the overall speed. If this is true what is the benefit of multiple cores if it has the same speed as a single? I am interested in speed only so if this is more for process sectioning i'll get whatever cheapest.

2. Is the architecture determined by the microprocessor?

3.What is the cache system in terms of cpu's?

4 Is there a good way to check cpu compatibility with the main board?

What makes such a radical and seemingly reasonless price difference?
5. AMD or Intel? :)(for price)

6. Do you know of a compiler for c++ that will compile to machine language of any kind (i don't care if its 16/32/64)
7. I wish to purchase the cheapest mainboard as possible that will work with my processor choice; any opinions on that?

8. Is the Tile64 processor any good?

9. I plan to cannibalize ram from my current computer but is there any difference in read and right speed in the same kind of ddr2 memory(or 3 if the mainboard supports it)?

10. I will be using windows (I would use ubuntu but the video games suck) but have you noticed a better utilization of ram and processing ability in windows 8 versus 7?(I thought it seemed better but expert opinion would be nice)

11. Alot of questions?

Answer 1

1. The speed it generally the maximum for all cores running at one time. The turbo speed is the max speed of a single core. And speed just refers to how many times a seconds the transistors flips, some instruction take multiple clock cycles. Different instruction sets can vary in actual execution speed of code a great deal.



Multiple cores can run multiple calculations at the same time. For a parallel optimized program a quad-core is four times faster than just one at the same clock speed. For sequential programs there is no difference as it can only use one core at a time. However having more that one core means you don't have to stop that process to deal with background processes and hardware interrupts



2. Yes, or more specificly the instruction set of the microprocessor.



3. More is better, AMD and intel set up cache diferently, which lead to subtle differences in performance for different tasks.



4, Yes, go to the main board's page on the manufacturers support page, and read the incompatibility tab or pdf. Most of the time however if the socket on the processor is the same as the one on the board you're ok. Some AMD sockets are backwards/fowards compatible, but the BIOS on the board isn't always, so check the official source when the socket is not exactly the same type.



5. The intel xeon has several feature that the amd trinity lacks.

ECC support,

QPI support (data link between multiple processors on a single board.

20x the cache

AVX isntructions

AES-NI instructions

and several other things that are valuable in servers



Is more energy effecient

And has a lot more calculation power (6x)



It's optimized for performance in a specific use case and does very well in it.



For playing world of warcraft, you wouldn't notice much if any difference though.



6. GCC has the widest architecture support.



7. Yes, don't do it. Get the features you need in a quality board. It will usually last longer and has better manufacturing support.



8. Yest it's very good for what it was designed for. If you aren't doing something like a high performance compute cluster, or filtering billions of network packets per second it's kind of useless.



9. Yes, and ddr2 is not compatible with ddr3. It will run at the speed of the slowest stick.



10. Yes, but there is less legacy compatibility with 8 and I think the windows 8 interface is plain annoying.



11. Yes, has your ISP blocked Google or something?

Answer 2

Answer to Q 11= Yes

Answer 3

If I bear in mind wisely, a number of the acceptable Canon DSLR have greater beneficial than one Digic processor. i'm no longer a Canon guy so i don't be attentive to. 30-40mp digicam exists. surely, PhaseOne P65+ has 60mp, and that's a "finished physique" medium layout. Smaller sensor digicam won't be able to do this, because of the fact greater pixel jammed into tighter area = undesirable photograph high quality. digicam ran on demanding force in the previous, it somewhat is asserted as the MicroDrive. it somewhat is a small demanding disk length of the compact flash card, and it went out of trend because of the fact it somewhat is not solid. demanding force makes use of greater power, and it somewhat is fragile. you do no longer choose your battery to die quickly or your information to get corrupted do you? DSLR *is* backward, yet then it somewhat works because it is going to. sooner or later the mirror will could flow, and cameras like the Panasonic GF1 or Olympus E-P1 will take over.
