Clocking in at 37 minutes. Don’t judge prog by the number of tracks… pretty typical album runtime for anything released in the vinyl era.
Also, it’s fantastic.
The options I’m looking at have PCIe 4 and seem to be gen 2? Epyc 7282 or 7302.
I think this is where I’m headed. Is there anything to consider with Threadripper vs Epyc? I’m seeing lots of CPU/MOBO/RAM combo’s on ebay for 2nd gen Epyc’s. Many posts on reddit confirming the legitimacy of particular sellers, plus paypal buy protections have me tempted.
Thanks, I’ll need to have a look at how the chipset link works, and how the southbridge combines incoming PCIe lanes to reduce the number of connections from 24 in my example, to the 4 available. Despite this though, and considering these devices are typically PCIe 3.0, operating at the maximum spec, they could swamp the link with 3x the data it has bandwidth for (24x3.0 is 23.64GB/s, vs 4x4.0 being 7.88GB/s).
Thanks. This is a pretty compelling option. I hadn’t looked at the entry level arc, but when it comes to encode/decode it seems all the tiers are similar. 30W is okay, and it’s not a hard limit or anything, just nice to keep bills down!
I hadn’t considered AMD, really only due to the high praise I’m seeing around the web for QuickSync, and AMD falling behind both Intel and nvidia in hwaccel. Certainly will consider if there’s not a viable option with QS anyway.
And you’re right, the south bridge provides additional PCIe connectivity (AMD and Intel), but bandwidth has to be considered. Connecting a HBA (x8), 2x m.2 SSD (x8), and 10Gb NIC (x8) over the same x4 link for something like a TrueNAS VM (ignoring other VM IO requirements), you’re going to be hitting the NIC and HBA and/or SSD (think ZFS cache/logging) at max simultaneously, saturating the link resulting in a significant bottleneck, no?
Thanks. I’ll be the first to admit a lack of knowledge with respect to CPU architecture - very interesting. I think you’ve answered my question - I can’t have QuickSync AND lanes.
Given I can’t have both, I suppose the question pivots to a comparison of performance-per-watt and number of simultaneous streams of an iGPU with QuickSync vs. a discrete GPU (likely either nVidia or Intel ARC), considering a dGPU will increase power usage by 200W+ under load (27c/kWh here). Strong chance I am mistaken though, and have misunderstood QuickSync’s impressive capabilities. I will keep reading.
I think the additional lanes are of greater value for future proofing. I can just lean on CPU without HWaccel. Thanks again!
First seeing this on my home feed on Jan 7th. Relieved to find the post is 5 days old…
