Xeon E3-1230V5 or E3-1260LV5

[Plato]

Hi,

I was building a new server with Xeon E3 chipset, but now I'm in a dilemma.. The CPU I ordered is now out of stock ( E3-1230V6 ).. I searched the market and found 2 used CPUs compatible with the motherboard which are cheaper than the 1230V6. I checked the benchmarks, and they look about same. Which one would you suggest to use in FreeNas?

Of those two, the E3-1230v5 for the higher clock speeds.

But what is your end goal/use case for this server? Both will be pretty heavy lifters, and have way more power than you need unless you intend to run a lot of CPU-heavy jails eg: multiple Plex streams.

I have the E3 1230 and have never had any issues running anything on my server. Plex as a use case works flawlessly with a couple of concurrent streams.

Well, I'll use it for torrent / jdownloader2 / usenet / plex / sickrage..

I was using Atom C2750 before.. It was enough for almost anything except re-coding 4K content..

As you can see from the usage it'll not be heavily loaded.. While I think 1230v5 is better because single thread speed is faster, 1260Lv5 is better because TDP is lower than 1230v5 and in the long run the electricity cost would be better for 1260Lv5 I think...

I'm not sure but I think Plex is re-coding 4K content with multi-threading, and 1260Lv5 turbo speed ( 3,9 GHz ) is higher than 1230v5 (3,8 GHz)..

So, what do you think?

A common assumption but it's wrong! TDP is about peak heat dissipation. It does not correlate with overall energy use.

There are plenty of explanations of this on the forums. Here's a recent one by @jgreco

Mind you, I have tired transcode with dual E5 2690 v2 and it can barely do 1-2 4K HEVC streams. Although newer E3s have avx2 I still don't believe it can do 4k transcode smoothly

I think you're wrong.

The idle power consumption of the 1230v5 and 1260Lv5 should be virtually identical. So when the platform isn't doing anything, you're not saving anything, not power, not heat.

One of the biggest differentiators is the hobbling of the turbo in the L processors. It's dialed back very aggressively. Intel hasn't made good information available about this for the E3 v5's, but here's the E5 v3 chart

https://www.intel.com/content/www/us/en/processors/xeon/xeon-e5-v3-spec-update.html

Over on page 9. So the instant you hit a second core running, both are likely to drop in speed fairly substantially. The 1230v5 is likely to be a better performer under load.

I just snagged up an E3-1270 v6 for its single thread performance in my machine. Got it on ebay for 220 bucks.
