MicroServer" with a "AMD Turion II Neo N40L Dual-Core Processor".<br>
<br>
It host lots of services on it:<br>
<br>
- mythbackend<br>
- some apache sites<br>
- p2p downloads<br>
- home NFS shares<br>
- owncloud<br>
<br>
I want to change the mythbackend to a dedicated server. I have 4 DVB<br>
devices (1 PCIe and 3 USB). I have two choices:<br>
<br>
- Intel Core2 Quad Processor Q9300<br>
- Intel Pentium Processor G2120<br>
<br>
Which one could you choose? Why?<br>
<br>
I will use the other CPU for a desktop PC.<br>
<br>
I am afraid about the electrical consumption, could I step down the<br>
CPU speed when I am not using it?<br>
<br>
This is a big upgrade to my mythtv system, so I want to be sure about<br>
the change<br></blockquote><div><br></div><div>Comparing those two processors is like comparing apples and apples.... I'd say they are about equal for average workloads. The quad will definitely win in multi-threaded scenarios while the Pentium would likely win in single thread tasks.<br><br><a href="http://www.cpu-world.com/Compare/494/Intel_Core_2_Quad_Q9300_vs_Intel_Pentium_Dual-Core_G2120.html">http://www.cpu-world.com/Compare/494/Intel_Core_2_Quad_Q9300_vs_Intel_Pentium_Dual-Core_G2120.html</a> agrees with my assesment.</div><div><br></div><div>I would go for the Pentium, mostly because it has a built in GPU, so you could use your backend for some light frontend use with VAAPI if desired without having to spring for a GPU. I use my backed as my Office TV... it's great. The Pentium is also lower power.</div><div><br></div><div>Additionally, tasks like transcoding may be a bit faster on the Pentium.. though multithreaded transcoding has come a long way so I could be wrong on this.</div><div><br></div><div>Now if these are two processors you have just laying around and want to put to use... either one is really overkill anyway.</div><div><br></div><div><br></div><div><br></div><div><br></div></div></div></div>
