AMD Radeon RX 6400 On Linux

[coder]

People would not complain about this or the 6500XT if AMD did any one of the following:

• Allowed it to be x16 lanes, or at least x8

x8 is all you really need for this level of GPU. Even at PCIe 3.0 speeds.

• Gave it at least 6GB of VRAM

Agreed, but that would put it into play for ETH mining, thus running contrary to your next point.

• Sold it for $120 or less

Agreed, but I think having even 4 GB of GDDR6 is going to keep it out of that price bracket, these days.

The silver lining would be if the supply chain issues settle out, then we might indeed see these cards drop to that price point or below.

What a piece of crap.

It's cheap, though. Name a card with a modern feature set that's cheaper (i.e. in terms of street price, new).

If you're just a desktop user, it makes plenty of sense to me. At my job, developers use machines with either iGPU graphics or a GTX 1050 Ti (for those machines without an iGPU or that have a 4k monitor). Those are totally fine, and this is way faster than either.

I wonder if it could be offered in a fanless design, like the GT 1030? GPUs with fans don't like me, they always die within one year.

If only it had VP8, VP9 and AV1 decode it would have been a perfect HTPC card...
Or if it had 4 miniDP it would have been a perfect office/work card. With that limited VRAM and PCIe lanes it's not even good for gaming.. Like this it's only good as a display out, but at that price you might as well get a GT710 unless you need HDMI2.1

gt710 can (perhaps) cope with a single 1080 screen, it is only good enough if you use very little graphical resources (desktops/windows/tabs). Even gt1030 may run out of its 2GB memory with a single 4k screen. So you want to have a card with at least 4GB ram if for 4k screens. gt710 is definitely not there.

Being able to play a game once and a while is a bonus.

It can also serve as a first step up for those currently using an iGPU, but I'd say it's only very compelling if they have an older iGPU.

It's three times faster than my 5700g and I must say that playing Shadow of the Tomb Raider at 80 FPS is quite a bit more pleasant than the 25 FPS in high settings at 1080.

I'm curious, how much less is this card is affected by that narrow bus than RX 6500XT? Kind of wondering if having it in a PCIe 3.0 setup is leaves less performance on table with this card.

In gaming? Hardware Unboxed has a review where they test both PCIe 4.0 and 3.0.
Briefly: It depends on the game, from almost nothing to very much.

They test it with 5950x though, not sure if it matters that much on other systems.

What? Ray tracing?!

Who makes the decisions for these cards?
What's more interesting? Hardware-accelerated AV1 decode or 10fps ray traced game?

i would buy a rx6400 if it had AV1 decode...

i dont know maybe the raytracing feature is for ultra-low-end raytracing games like Doom1.0 RT mod???
but on the other hand ultra-low-end games like Quake2 RTX also eat a lof of performance...

lowest end amd who has AV1 is the 6600.
i think intel will sell many 6400/6500 like cards with 64bit ram channel only because they have AV1 decode...

The RX 6400 is supposed to be primarily an OEM variant of the RX 6500XT.


Maybe, but it doesn't make any sense to have a dGPU that's any less powerful than this. I think its main market is for non-gaming use in systems that lack an iGPU.

It can also serve as a first step up for those currently using an iGPU, but I'd say it's only very compelling if they have an older iGPU.

I think this would fit pretty well in a multimedia (live sports stream - the official kind, video playing and light gaming) even for more than just a first step. Especially with the likely low consumption and noise (single fan).
Plus, my case is a flat HTPC case (the flat micro-ATX type with just 12 cms high for the graphics card (not much choice at this height, believe me) and this would fit the bill.
One more thing to take into the mix, is that paying more than 200€ for a video card is a no-go for me and my life priorities (only occasional time to spend on video gaming).
