Single Thread CPU Benchmarkings and the Effect of a Second CPU on the Single Thread Benchmarking

[PeterKSH]

The Single Thread Benchmark from cpubenchmark.net is 1.526 for a Intel Xeon OCTA Core E5-2665. But this is based upon a single processor/CPU and the computer I am thinking of buying has 2 CPUs . (It is a dual processor computer.) Will a second CPU affect the single thread benchmark by adding approx. 50% to the benchmark of 1526 resulting in a single thread benchmark of around 2300 or can only 1 CPU affect the one single thread and so the single thread benchmark cannot be affected by the presence of a second CPU? In effect I am asking if 2 cpu's can work together on the same thread to produce a higher single thread CPU benchmark?

No. Single thread is EXACTLY what it says. One single instruction stream on one single core. A single E5-2665 has multiple cores on the chip. No matter how many of them you have, single thread will be the same.

Thanks for replying Kanewolf. I want this PC for playing virtual instruments and for recording and the like. Spectrasonics--who make some of the virtual instruments I want to use-- recommended getting if possible 12 cores. Also a fast processor and 64Gb or at least 32Gb or RAM. The PC I am thinking of getting has 16 cores and 32 threads but its single thread benchmark is only 1526 much less than an i7-67OO as can be seen following:
Single Thread Benchmarkings:
Intel Core i7-6700K @ 4.00GHz 2352 but its multithread benchmark is only 9,092
Intel Core i7-6700 @ 3.40GHz 2160
Intel Xeon E5-1620 @ 3.60GHz 1935 This PC base price $600 but multithread value is only 9,092
Intel Xeon E5-2665 @ 2.40GHz 1526 Dual processor $1400 but multithread value is 17,648 !

After your remarks about single-threading I wonder if the burst strength of the E5-2665 is too low. The $600 E5-1620 is quite a bit better on single thread benchmark but it only has 4 cores and 8 threads and a max RAM of 64Gb. It would be maxed out on RAM when I bought it. The E5-2665 would have 64Gb but could be upgraded later to 128Gb if needed.

What do you think of dual processor Intel Xeon E5-2665 @ 2.40GHz for real-time music production and recording? Should I be concerned about its low single thread benchmark?
Do you know of any used computers for around $1000 USD with fast throughput and multiple threads coupled with the potential to use 124 or more Gb of RAM?
