To really quantify things, you need to look at the minutia of |
20 |
how the processors are interconnected, bandwidth, and a host of |
21 |
very hardware oriented details. From a commons sense approach, |
22 |
better performance must be achieved from the smaller sizes |
23 |
of the transistors and such on the new 65-nm processes that are |
24 |
used to build such multi-processor semiconductors. You can spend |
25 |
a huge amount of time drilling down into these details, if |
26 |
you want to. My experience is all that performance requires |
27 |
and extra premium in costs from the purchaser to make the |
28 |
suppler rich (or at least enough money to design the next chip). |
29 |
Intel extracts a bit more profit from the user than AMD, because |
30 |
they can. Just like Nvidia make more money than ATI..... |
31 |
|
32 |
That said, I like AMD products, but, it is a choice. |
33 |
|
34 |
|
35 |
The better questions to ask are: |
36 |
1) Does the linux kernel run on this processor? |
37 |
2) Does the extra cost seem reasonable for my needs? |
38 |
3) Ask any minutia questions to some kernel experts |
39 |
(for example maybe kernel.org or Intel have some |
40 |
published benchmarks) |
41 |
4) Look for relevant benchmarks (benchmarks are like |
42 |
statistics, folks publish what promotes their position. |
43 |
5) Just by the dam thing and enjoy the hell out of a smokin |
44 |
box that the rest of us only dream about.... |
45 |

|
47 |
(don't forget to purchase generous amounts of the fastest |
48 |
ram the machine supports, or your pissing away your money. |
49 |
Large L2 cache and the fastest memory available for your |
50 |
processor dollars are usually the best choices, in my experience. |
51 |
|
52 |
Also look into heating issues and possible using a water cooling |
53 |
system to extend the life of the processors and keep the |
54 |
dB level down to something reasonable.... |
55 |
|
56 |
Personally, I put off purchases as much as possible, but when the |
57 |
time comes I get a 'one off' of the latest and newest, to stretch |
58 |
my limited dollars (or those whom I work for). |
