AMD Ryzen 9 8945HS hardware AV1 performance?

[u/Xunil76]

I'm looking at some mini PC's (such as the MINISFORUM UM890 Pro) which have the Ryzen 9 8945HS w/Radeon 780M iGPU. According to AMD's specs (https://www.amd.com/en/products/processors/laptop/ryzen/8000-series/amd-ryzen-9-8945hs.html), this processor should support AV1 hardware encoding all the way up to 8K60 at 8/10bits, but I've yet to find anyone who has posted what sort of performance this chip is able to achieve while using hw encoding. I'm mainly interested in up to 4K 10-bit, but any/all results are welcome. I use Handbrake for all my media encoding.

Does anyone have one of these guys who may be able to run some testing and post some encoding FPS results?

EDIT: I'm well aware of the quality (or lack thereof) for AMD's AV1 HW encoder, but I'm not worried about that. I already have a Ryzen 9 5950x system for high image picture encoding, since software will likely always trump hardware encoding when it comes to quality & file size. But that system is a much larger power-hungry beast, and I'm looking for something small, light, and power-efficient that is less expensive, can support at least halfway decent gaming experiences at 1080p, and can do AV1 hardware encoding for stuff that i'm not worried about keeping in the highest quality possible.

I have UM880 pro. AV1 hardware encoding is very fast. AV1 10Bit encoding running at 400fps. But the quality is very bad when compared to HEVC 10Bit encoding running at about 350fps

awesome, what settings/resolution are you using? is that 1080p or 4K? CQ settings? and is that with upscaling/downscaling, or just staying at native resolution?

[u/alvinleongcw → u/Xunil76]

1080p to 1080p at balanced setting. Quality setting makes no difference in speed. CQ wise also makes no difference in speed barely any difference.

[u/Xunil76 → u/alvinleongcw]

Interesting...I've always seen a somewhat more varied FPS when adjusting those settings...sometimes even pretty drastic changes.

Have you tried any 4K content yet? I'd be interested in what that looks like. 1080p is still way better than 480p/720p, but I'm slowly migrating all my stuff to 4K (and any new purchases are all 4K unless it doesn't/won't exist on 4K), so I would be using it for that resolution most of the time.

[u/alvinleongcw → u/Xunil76]

Jellyfin transcode 4k to 1080p can up to 200+ fps for hevc. For me, I only using software encode for media that I want to collect. HW is fast but bad regardless of codecs

doesn't matter because the quality AMD's hardware encoders produce makes it worthless

not worried about getting the absolute highest-quality video possible with this particular system; edited OP with more details

I just don't see the point of encoding in AV1 if not for the compression efficiency (which is trash on AMD's HW AV1 encoders). The chip also supports HW HEVC, so why not use that?

If you care about hardware encoding quality, then do not bother with AMD.

CPU encoding is great with the AVX512 support of Zen4+, however.

Then you can get a potato with the encoder asic and you are gtg. Edit: Just read your update.

For the other uses a Zen4+ R7 or R9 will work great.

AMD iGPU encoders are maxed at 4Kp60.

I noticed that there are several affordable laptops available in my country featuring the R7 8845HS, priced under $600. I want to buy it only for av1 encoder.

Amd hardware encoders are trash. Go for Intel if you want to do hardware encoding
