Which processor to encode x265 4K ?

[Atak_Snajpera]

It is easy to predict that 3950x will be on top of the chart with score around 70fps beating 2 x Intel Xeon E5-4660 v3 @ 2.9GHz ( 14C / 28T ). I just can't wait to see TR 64C/128T result However I personally doubt that five x265 encoders running simultaneously will be enough to feed that beast.

So after Ryzen 3000 release, do you think 3700x is a good CPU to encode to x265 ? Or do you think it's better to wait 9900K at a lower price ? Thank you !

So, in other words Ryzen 5 2600 is ~13% faster in x265 encoding than Ryzen 5 1600, but Ryzen 5 3600 is ~55% faster than Ryzen 5 2600 and ~75% faster than Ryzen 5 1600.

Faster clock and mainly AVX2 implementation makes big difference for x265 obviously.

If you're going to debate about that, might as well get the 3900x as it's the same price as a 9900k, with far better performance. I mean if the 9900k was in your budget, and you're not just looking for a reason to cheap out :P haha.

Thank you, I just ordered a Ryzen 7 3700X now I'm searching a motherboard and DDR4. I think I'll go with a B450M. Do you know the motherboard and RAM used on this test ?

ryzen 3000 chips won't work on some non-x570 motherboards at all and some won't work without a bios update which may require an older am4 cpu to flash the bios. Research boards before ordering.

I found the MSI B450 Mortar and it can be flashed without CPU

Regarding memory, take a look at this:



No need to go overboard with memory, the difference is quite small but you could end up paying quite a lot extra. Personally I run my 24GB at 2866C14, which means the calculated latency is ~9.76ns. I'm not going to buy faster memory in case I upgrade to Zen 2, unless I get a real bargain.

Look at this list of motherboards and pick one that has at least 2 green squares : https://docs.google.com/spreadsheets...#gid=639584818

Thank you, I already looked at it and I'll go with the MSI B450M Mortar

Thank you, very interesting.
IMHO the 2700X is missing in this benchmark, it would be interesting to compare 2700X and 3700X.

2700x will be only slightly faster than 1700. 2700x still has avx128.

This. I have a 2700 and it's not much faster than the 1700 that is in these benchmarks. In fact I am currently doing a 1080p slow encode and only getting 6.07 fps, which matches up with their results.

Time to upgrade! So much great information in this thread.

Just keep in mind that MSI decided to be weird and requires you to first install BIOS v17 before you're able to successfully install BIOS v18 (which is the newest).

And yes this applies to when using their CPU-less BIOS flash function as well.



EDIT: It's since come to my attention that the v17 and v18 version numbering only applies to the B450 Tomahawk.

Therefore, a more accurate way of phrasing my statement would be that MSI requires the user to first install the March 2019 BIOS before one can then successfully install the latest June/July 2019 BIOS.

Thank you so I must install v17 BIOS with CPU-less function ? And I don't see v18 on MSI Website, I can see only v17 and it supports Ryzen 3000 :
- Support Ryzen 3000 series CPU.
Ryzen 9 3900X/Ryzen 7 3800X/Ryzen 7 3700X/Ryzen 5 3600X/Ryzen 5 3600/Ryzen 5 3400G/Ryzen 3 3200G

Oh, hmm. Comparing it to MSI's more popular motherboards like the Tomahawk, it looks like the version numbering on the Mortar is one value behind for some reason...

Therefore you actually might have to install BIOS v16 first before being able to successfully install BIOS v17.

And for reference, you would have to do this even if you were updating the BIOS via the traditional method.



EDIT: OK yeah, it looks like the v17 and v18 version numbering only applies to the B450 Tomahawk.

And bear in mind that fastest is going to depend more on per-core performance for lower resolutions, but will be near linear to number of cores for higher resolution. My new Dual Intel Xeon Gold 6140 workstation should be arriving tomorrow. I look forward to testing how well it scales at 4K and 8K.
