Is the L5639 really better than L5520?

[uberguru]

I have seen the new C6100 coming out with L5639 processors and i just want to know from people who have benchmarked or tested both to share if there is really much better performance from the L5639 than the L5520. Yes i know L5639 has 6 cores and L5520 has 4 cores and both use 60 Watt TDP...but after looking at cpubenchmark i didn't notice much performance difference

1 x L5520 CPU SCORE 4324 (Dual CPU will be 8648)
PassMark - Intel Xeon L5520 @ 2.27GHz - Price performance comparison

2 x L5639 Dual CPU SCORE 8580
PassMark - [Dual CPU] Intel Xeon L5639 @ 2.13GHz - Price performance comparison

One, those benchmarks are not the greatest tool for picking out cpu's. The second thing is that you are not comparing apples to apples. You cant just simply double a single cpu and say its going to get twice the score. If you want to use their actual scores, the dual 5520 is actually only 7720.

Compare SR-IOV performance.

Compare memory capacity performance( 288gb/1333mhz)

Compare AES-NI (got ssl?) performance.

Compare active cpu turbo boost(1?2?)/power consumption/heat.

Compare SLAT performance.

I think those scores are slightly better than worthless. mrkrad had a good breakdown. L5520's are good for cheaply filling boxes. L5639 is my choice for performance.

mrkrad the 32 nm shrink also had a small instruction per clock boost
