I would think Intel D2500CC is a better choice for it has 2 ports with Intel NIC.
Both boards suck with PCI slot.......

嘩..你老闆 ,這塊有 DC IN

做 fanless 動物機仔真係無敵喎！連 Flex-ATX 火牛既嘈吵問題都完全解決！

係差在得 2 SATA port

pc router or NAS

but still slower than E-350 / E-450?

D2700>E-350, no idea for E-450.
Anyway they are all unsuitable for a 1Gbps router, if that is what you may expect.

The only bench I have read:
http://www.nordichardware.com/ne ... m-d2700-testad.html
I am not sure if it is reliable though.

Updated:
From passmark it seems I was wrong:
http://www.cpubenchmark.net/midlow_range_cpus.html
while it's unlikely to have so little gain over D525 as well, maybe a more detailed bench is needed.
D2700 is theoretically 1.18x of D525.

CPU performance can't handle to use for 1Gbps router?

From pfsense forum,
Intel Atom D525 = 550Mbps, you may estimate the other CPUs(similar microarchitecture, x86) for their expected value of throughput by scaling.

PS : Intel Celeron G530 : ~30% utilization at 800Mbps, meaning it can handle up to ~2600 Mbps.

I CANNOT confirm.
Simply from scaling it doesn't, maybe I can search for it in pfsense forum.
Internet contains really scarce information for 1Gbps NAT throughput of x86 routers.

OK, you may now chase this for any ans:
http://forum.pfsense.org/index.p ... 4358.html#msg244358

Btw, some hints may help, but I have to further confirm if that guy has PowerD on(which throttle the CPU and affects the calculation)
http://forum.pfsense.org/index.p ... 1978.html#msg201978
In case his value is correct, E-350 cannot push more than 600Mbps.......

so, for 1Gbp internet, which CPU can recommend?
G620T?

I would suggest G530, which is cheap and guaranteed.
For G440/460, I am not sure but they MAY have the job done as well, need to test.

你呢個test...
PC Mark 2012 (廢既, 有人試過VIA CPU remark Intel string, 分數即刻高左)
Cinebench multihread, 睇下面
3DM主要係discrete HD6470M vs IGP HD6310, 無得講

D2700 = D525 @ 2.13GHz
Bonnell由2008年之後無改過

http://www.anandtech.com/bench/P ... 9.40.41.42.43.45.46

[attach]20459[/attach]
由呢幅圖睇到,
E-350 single thread performance快好多
Atom主要係靠HT追番上來

E-450 = E-350, 果3% freq difference (1.65GHz vs 1.6GHz) 當佢無到

Atom:
1. 低d idle power consumption
2. multi-thread performance (如果真係用到)

E-350:
1. single-thread performance
2. power efficient @ full load

D510=1.6, D525=1.83, D2700=2.13,
the score in Cinebench for D2700 should be ~1.33*709=Cinebench:942.97, D525=Cinebench:810
while for routing it should be largely a single thread issue, E-350 maybe a better choice on it. I am not sure if HT would help.
D525@Cinebench:810=550Mbps, then E-350@Cinebench:1174 should be around 797Mbps, ignoring the effect of HT.

797Mbps is not bad for a router as BB1000 offers around 80% only. While concerning upload and downloading happening at the same time this will be insufficient as well as VPN's performance maybe not as desired.

I don't know if the modified Linux can handle mutli-thread well or not
So I cannot answer

If you really need 1Gb+ NAT performance, G530 is the minimum

Not really if you have more than 1 computers and active users.
