Knowledge on processors

[maxirox]

Hi!

Sorry to post such a long question. I need to understand every aspect
of processors and would like experts give answers to the following.
There would be many more people like me who would be curious to know
these answers and this post will help them as well. It would be better
if somebody an make a webpage out of it and post it somewhere where
everybody would understand in and out of processors.

Question1:
Which architecture is the best in terms of processing?
1. 0.13 micron technology
2. 0.18 micron technology
3. 65 nanometer technology
4. 90 nanometer technology

Question2:
What is the difference between the following and which one is the best
in terms of processing?
1. 2 MB L2 Cache memory
2. 2X1 MB L2 Cache memory
3. 2X2 MB L2 Cache memory

Question3:
What is L3 Cache?

Question4:
For better understanding answers to the above questions and give an
example, sort the following processors in terms of their processing
speed. The fastest should be listed on TOP.
1. Pentium 4 Processor Extreme Edition supporting Hyper-Threading
Technology, 3.46 GHz, 1066 MHz FSB, 512 KB L2 Cache, 2 MB L3 Cache,
0.13 micron technology.
2. Pentium 4 Processor Extreme Edition supporting Hyper-Threading
Technology, 3.40 GHz, 800 MHz FSB, 512 KB L2 Cache, 2 MB L3 Cache, 0.13
micron technology.
3. Pentium 4 Processor 651 Supporting Hyper-Threading Technology, 3.40
GHz, 800 MHz FSB, 2MB L2 Cache, 65 nanometer technology.
4. Pentium 4 Processor 650 supporting Hyper-Threading Technology, 3.40
GHz, 800 MHz FSB, 2MB L2 Cache, 90 nanometer technology.
5. Intel Pentium D Processor 950, Dual core, 3.40 GHz, 800 MHz FSB, 2X2
MB L2 Cache, 65 nanometer technology.
6. Pentium Processor Extreme Edition 955, 3.46 GHz, 800 MHz FSB, 2X2 MB
L2 Cache, 65 nanometer technology.

Question5:
Define the following technologies:
Hyper Threading
Dual Core
Intel EM64T
Execute Disable Bit
VT
XD
EIST

Question6:
What is the difference between the following packages?
FC-LGA
FC-PGA2
FC-PGA4
LGA 775
mPGA 478
PPGA INT2
PPGA INT3

Question6:
What is the difference between LGA775 and Socket slot type?

Question7:
What is the difference between the following pin counts?
775-land
478-pin
423-pin

Thank you
Maxi

This looks suspiciously like class homework. It's all reserchable.

I'll give you a start. 0.18micron =180nanometers. More cache is better,
faster bus is better. 423 is an obsolete p4 processor.

Hit AMD and intel's website. Wikipedia is good with computer type
stufff.

Hi!

Sorry to post such a long question. I need to understand every aspect
of processors and would like experts give answers to the following.

HAH!

Those who engineer CPUs would probably like to know "every
aspect" of them, too. It takes teams of people, years of
learning, for a single architecture. A summary in a usenet
post would be pitifully incomplete.

There would be many more people like me who would be curious to know
these answers and this post will help them as well. It would be better
if somebody an make a webpage out of it and post it somewhere where
everybody would understand in and out of processors.

Ok, do that and post a link.

Question1:
Which architecture is the best in terms of processing?

Define best

1. 0.13 micron technology
2. 0.18 micron technology
3. 65 nanometer technology
4. 90 nanometer technology

Smaller feature size allows more CPUs per wafer, but
requires the technological know-how to do it. Smaller uses
less power and can run faster in general, but overgeneralize
and you have an idea not necessarily applicable to any one
CPU.

Question2:
What is the difference between the following and which one is the best
in terms of processing?
1. 2 MB L2 Cache memory
2. 2X1 MB L2 Cache memory
3. 2X2 MB L2 Cache memory

The difference is as read.
Best depends on the job. I agree with Paul that these read
like homework questions and they are dumbed-down questions
at that, because they expect only a rudimentary knowledge of
popular concepts. The generic dumbed-down answer would be
that 2 x 2MB is best, but in reality, a given architecture
might be able to run a 1 x 2MB cache faster, or depend on
the technology available when it was made to determine it's
speed, and the size of the working code will determine how
much cache is of significant benefit before you get to a
point of diminishing return.

Keep in mind that these are not complete answers, you need
to have a context to decide which parameters matter most (if
at all).

Question3:
What is L3 Cache?

L = Level. It's another level besides L2 or L1, usually
larger and slower than the former two. It might be on the
CPU die or carrier - it might not.

Question4:

Sorry, only 3 questions allowed. You can look up benchmarks
for these anyway, benchmarks are common as dirt.
