   Interestingly enough mine came preloaded with v3.31

   Something you may or may not have noticed is that the switch chips on these (similar to the RB450G) support up to 32 firewall rules on the switching side (before anything hits the router chip) which is supposed to mean the switch can still do wirespeed throughput even with a few firewall rules.

   In testing I could get around 50Mbps TCP traffic (using btest/bandwidth test) with traffic generated from the Mikrotik unit itself* which is about 10Mbps improvement on the RB750 however the switch chip benefits are awesome as well.

   *I do this as I believe it gives a more ‘real-world’ figure, simulating some loss of throughput due to additional firewall rules that will be added.

   I also got mine free thanks heaps to my local supplier duxtel (shop.duxtel.com.au) who sent me a freebie to use/test. 🙂

   I did notice this good stuff in the switch chip comparison. There were what…4 different sets used, each with its own attirbutes. I wonder how it knows which FW rules to dump to the switch ASICs…perhaps just the first rules in the chain?

   First I want to know how your supplier got their 750Gs before mine did…mine won’t be here until next week! 🙁

   I was able to sustain 50Mb of throughput with the standard 750 while only using around 40-50% CPU, so I expected to eak a bit more out of the G…

   I’m going to test my RB750G with roughly 50Mb of throughput and terminating 3 or so IPSec tunnels doing 2-3Mb of throughput each. That’s where I see the RB750G, as the headend for a hub and spoke IPSec network. 🙂

   Friend, I am of the brasil, it excuses for my English, that rb750g and better than the rb450g

   Marcos,

   The 750G has more processioning power than the 450G, but the 450G has more RAM.

   The 450G is a good option if you want to do metarouter or if you want to hold the full internet route table, otherwise I would use the 750G.

   Thanks for the question.

   Greg, how comes “750G has more processioning power than the 450G” if they share the same CPU while 450G has 8 times more RAM?

   Edmidor,

   I can’t really tell you sir. You will have to post on the MTK forums for a hardware design question…sorry.
