So what is it about then  ! With Intel ht you don't really get more cores, its just the same cores that are loaded somewhat differently by the software (below 100% load anyway). What more is there to gain? Track peaks are 100% load and in inbetween zero (save for some pre and after peak activity). Regards, Coen |

Hi Coen, You might probably know that XXHE is multi-threading sensitive application. Speed per core is not as important as more cores. Intel disables HT on their chip and labels i5. This way they can apply premium pricing strategy by enabling HT on i7 chip. They are all coming from the same wafer. So you have desktop i5 in which HT is not available. Please check this out : http://ark.intel.com/products/series/53248However, the mobile i5 has dual cores with HT to 4 threads. I ran 12 threads and it is lightening fast to load FLAC tracks. Hope this gives you more transparency. Rgds, Praphan |

Coen, HT = Hyperthreading (each physical core can behave as two logical ones). An i5 can't do that.
For an i7 it must be switched on in the BIOS.
Further see Prapan's post.

Yes, I am aware that HT is not possible with i5.
Is this multi core thing only about FLAC decoding or more about SQ?
I usually play WAV for optimum SQ.

Thanks Praphan,
I am just getting the finger behind 'real' vs 'HT' cores. The virtue of HT is more efficient use of the cpu when multi threaded applications run. This effect is real but is in the order of 10% more instructions in a given time (in those specific mt applications) than without HT.
Sq wise this may be important. Critical listening to ht on/off on my atom setup favoured the standard two core (ht off) over the "4" core (ht on) situation though.
Increasing the count of real cores most certainly helps. I have been considering amd legacy 6 core and 8 core bulldozer for that matter but found bost cost and powerconsumption prohibitive. The same costlimitation goes for the new 6 core i7s (from 580 euro up).
The i5 system certainly feels responsive and handles all -demanding- configurations with ease (no glitches whatsoever).
Regards, Coen

This weekend I did a little speedtest. Since i have an unlocked processor, I switched of EIST and underclocked the processor to 2.5GHz (coming from 3.3 with 3.7 turbo). This seriously impaired the handling of XX. Everything takes much more time, for a split second I even had the idea that te atom was back  . This confirms my idea that pure core horsepower remains important. I am convinced that the system could even be faster with a cpu that supports more threads, but that comes at a price premium that you have to be willing to pay. Happy listening to ya all, Regards, Coen |
