I have question regarding value between E5-2448L vs E5-2620. This is a real question for me.
Assumption, this is for home lab , not for business .
I checked Ebay sold listing, there were two retail / oem version of E5-2620 sold $250 and $275 each.
I understand E5-2620 is 6 core vs E5-2448L is 8 core.
My experience is that E5-26xx is faster than E5-24xx clock for clock, may make up for the performance difference.
E5-2620 system cost:
Tyan dual LGA2011 board ( purchased 2 board at $100 each, 1 board with LSI at $140 each): $140
2 x E5-2620: $275 x 2 = $550
Total = $690 or $650
With 1 single E5-2620 total cost = $410 or $375
E5-2448L UP system cost:
Intel S1400Fp2 UP board: $150
E5-2448l: $280 x 1 = $280
Total = $430
E5-2448L DP system cost:
Intel DP board: $190
E5-2448l: $280 x 1 = $560
Total = $750
With similar price, I prefer LGA2011 board over LGA1356.
