Q9550 Vs Xeon L3426 for encoding

[Matrix]

Just a quick question i was speaking to a friend at work today and he said the xeons like the L3426 are equivalent to a I7 Cpu?

And that the L3426 (4x 1.86GHz) turbo boost on the L3426 gets it up to 3.2ghz on all 4 cores (8 logical because of HyperThreading) which encode a lot quicker than a Intel Q9550 does.

Is this correct?

Reason i'm asking i own a Q9550 and he is selling a Xeon L3426 so i might be interested in it.


Thanks and hope someone can answer my question.

I assume you realise the L3426 won't fit in the motherboard your running the Q9550 on.

If your encoding something that can make effective use of the extra HT units then you will see a decent performance boost clock for clock over the Q9550, otherwise you'd only see a very minor performance increase (approx. 9% on average) clock for clock over the Q9550.

Thanks for that what about a Xeon L5630 (8x 2.13GHz w/HT) would that be much better?


Thanks.

Similar situation as the L3426. The performance in heavily threaded applications will be better - so encoding speeds should be improved.

However, again it won't fit in your existing LGA775 motherboard (in this case it will need a LGA1366 board that supports it) and you would need new RAM (assuming you are using DDR2 now).
