pfft i hear you say :D

im looking at my server 2016 mediaportal htpc that runs with a 8320&16gb RAM,ssd, it also host a few hyper-v vm's so the core count comes in quite handy though there not cpu taxing.

It does the job very well, its paired with a ATi passive gpu to deal with any decoding. for the most part i dont think it needs upgrading. but the apu's are tempting as i can do away with the ancient gpu (3450?!) and cut on the power costs with future proofing it.

do you think its a worthy upgrade? the cost to replace the cpu/mb/ram is ~£200 and i can sell the parts to offset that so in real terms your probably looking ~£100 for the upgrade.
 
No idea on power draw :) other than the 8320 is a 120w processor in a machine that is on 24/7, it probably never breaks a sweat though!
 
Hmm, it's kind of hard to quantify if it's worth it without actual figures for your kind of usage, you could use HWMonitor to get approx figures for the CPU, but a plug-in monitor would be better since it'd include the whole system. Is the 8320 actually at full load for much of that time? I'd be surprised if it was really using 120 watts from what you described. That GPU seems to use about 10 watts in 2D, not sure for the 8320, perhaps 50 - 60 watt idle for the whole system, compared to 20 - 30 watt for the 3200G?

The 3200G reviews (max multi-threaded load) say it tops out < 100 watts (whole system), while the 8320 would top out < 200 watts, the 3200G is also more energy efficient, with much faster single core performance.

If it saved 40 watt idle 24/7 then that's £50 a year, for 8 hours it's around £20.

Under load, we could assume a saving from better efficiency, but I'd be surprised if it was more than say... the equivalent of 50 watts for 8 hours a day, which is £25.

I used https://www.cryer.co.uk/brian/misc/how_much_electricity.htm for the figures, which assumes electricity price of £0.15 a kwh.
 
nice one :) with a more conservative saving estimate on elec it should pay for it self easily over the +3 years its likely to be in use before the next upgrade! Its a great machine but ddr3 & am3 are now going grey quick!

thanks for help!
