This seems to be an excellent card if you desperately need to something to plug a monitor into and have no other choice.

Thanks for the review. It's an ok card for the price which i still a bit over priced, but it is what it is. If this card would had cost no more than $120 USD i would bought one for my kids PC which as a PhenomII x4 965BE, 6GB DDR3 and R7 240 2GB. They just it mainly to play Roblox, Fortnite and Genshin.

This is a cool GPU for OC contests. Solder your own additional VRM's, a 6 pin power header, larger capacitors and happy clocking.

I guess it would be fine for home theater use or for an old DELL office machine with no 6 pin PCIE cable.

Thanks for the review! :respect:

Like I thought, this card is everything the 6500 XT should have been: a low-power HTPC GPU with single-slot options, and light gaming capabilities. One could say that it's still too expensive, but considering that low profile versions of the 1650 go for £250-300 on ebay, £160-170 for a brand new equivalent is actually quite good. I've already ordered the Sapphire Pulse RX 6400 for my HTPC (1. It has HDMI 2.1, 2. I'm curious). If anyone's interested how it goes, let me know. :)

Should've made this GDDR6x or at least 128bit wide bus, it's like the low end is still stuck in the 2010's or something :shadedshu:

RX 6400 spec table in the first page is wrong. Cores number must be 768. (3/4 of RX 6500XT)

PS. This GPU recall my memory of the graphic in name only but not suit to play most game => "Radeon HD 2400XT".

Results should be similar, not sure if worth doing another round of testing

At least, you will show at what bandwidth PCIe setting the performance tanks considerably. Please do it.

I mean there should be a tutorial educatory review which enlightens the potential buyers why not to buy this low-performing card.

With GDDR6, it has the exact same bandwidth as the 1650 with GDDR5. I don't think it needs more with this class of GPU.

I don't think the impact is so severe with the 6400 (at least I wouldn't hope so), but I'm quite curious too! :)

My 6400 is going into a pci-e 3.0 motherboard, although I won't be playing games on it.

For a low power GPU that has limited gaming capabilities, the lack of AV1 decode is disappointing, since the AMD APUs can't do it. Only the higher end GPUs and I think the Xe iGPU on the newer Intel CPUs can do it. If you want a future-proof HTPC streaming media card, this was a missed check box.

This is pretty much a 750ti/1050ti class GPU except that Maxwell GPU was released over 8 years back & Pascal one over 5 years back! According to TPU charts it's still not 2x as fast as 750Ti & barely faster than 1050Ti, I think AMD should really do better after so many years especially in this segment. This belongs to 1030GT level right now & shouldn't cost a penny above 100 USD, the segment which it's released into right now is horrendously overpriced ~ granted Nvidia also haven't released anything of that kind like a 3050ti without power connector but the point remains!

this completely destroys the 1030, which also lacks encoder and has 2gb of ram.

this is a 1050 level, in any case, the 1030 is a silent 20W card, this is not.

I'd see what encoding/decoding and display connectivity similar offerings from nV/Intel will end up having. It's too expensive for what it is anyways.

There seems to be power to spare in these things...unless the target here is a replacement fr RX 550?
Frankly, does RX 6400 beat RX 550 or RX 560? 6500 XT actually failed to beat 5500 XT.

amd becoming the new intel FML
Started happening ever since Ryzen 5000 series were launched. AMD at that point was already rotten.

TPU, thanks for the comparison to the 560 2GB. I have a low profile 460 2GB in my HTPC, and was considering the 6400 as an upgrade. This pretty much cements that decision. I didn't expect it to be over 2x faster. This should allow 1080p vs. 720p gaming.

A couple of points about the review:

* all the benchmarks say 6400 xt rather than 6400
* i assume the 1650 being compared to is the obsolete 1650 gddr5, not the faster 1650 gddr6, which is one of the best selling GPUs, at least in my market ?

The 1650 (gddr6) runs about $30 more expensive, so there is that, but otherwise it seems like it is so much better thanthis thing in every respect.

Couldn't help but notice the 6400 in this review and the 6500XT only differ in clocks, and that OCing is locked out.
Any chance of a modded 6500XT BIOS being able to be flashed onto the 6400s?

New AMD and Nvidia GPUs will be targeted at entry-level gamers, wanting to spend less than $200 for their graphics card to turn on the computer and play minesweeper.
In the other news, you can now play Crysis on your phone, once a graphically intensive game on PC now easily handled by even the cheapest 200$ phone.

Right & that's also what a 3-4 year old card?

Like I said 750Ti/1050Ti segment & barely faster than those two all these years down the road, yes Nvidia themselves haven't replaced those cards with 3xxx GPU's but AMD really should've done better than this one!

Can anyone clarify the performance differences between the aero model on this review and LP model for Witcher 3 here?

Skip to 8:48 am I missing something? Thanks!

*Edit* Nvm its clearly because this review all games are on 'maximum quality' settings aka Ultra,, makes it hard to gauge real-world performance given the huge difference between max & high(what makes more sense to actually run). Appreciate the testing but yeah, here I was thinking this card is no good for gaming on high 1080p /w 60fps.

I have the same use case in mind. I already wanted a HDMI 2.1 a year ago and bought a RTX 3060.
Why did you buy the Sapphire one?
I'm thinking about the Powercolor RX6400. This one has 0db fan stop.

You noticed wrongly, as the 6400 also has only 12 CUs compared to the 6500 XT.

Still, they're the same chip, so unlocking one to the other could be technically possible when the lower end SKU uses good silicon. Big 'if', though.

"Remember, there were times when entry-level graphics card cost around $100"

yeah the same time 11 bucks a hour was consider decent in low cost non city's now be 14-15+ or wtf and over a year fyi that is a ton of money before any overtime if you want to do math... companys cant pay enginers and taxes and ect ect ect cant and do 100... keep in mind tech is CHEAP now.. the neo geo console was 649.99 dollars in the 90s when if you made 11 bucks you were doing decent for yourself...( and a low end computer could cost like 2k again a TON for the time) perspective boy perspective..

you have to pay the warehouses, driver if not the brick and mortor ppl.. before the tech and actual cost of copper ect ect of everything they use...(just to have a physicals item that works is a base cost then the ppl who ship or stores who stock it... this is the 1030 again... 100000% just dont go super cheap ppl dont do that when they buy plains or cars their is a mimmum cost you want
"its to high becuse its power is to low"... if you said it before then you are wrong before... unless you think ppl should make 30k or less to stock or ship stuff like food other items
... is this directed at me? Because it doesn't seem applicable to what I'm saying. I get that much of what I've said on this is in another thread, but, well, you're preaching to the choir. I'm perfectly in line with price increases being understandable. What isn't understandable is this entry-tier GPU being priced at $160 - that's simply too high. This is a lower tier than cards like the 1050 and 1050 Ti that launched at lower dollar prices just six years ago, and there hasn't been that much inflation since then. Remember, the 1050 Ti launched at $139 and the 1050 at $109, for 50-tier products in late 2016. I'm arguing this should be around $120, for a 40-tier product ~5 years later. For reference, $139 in 2016 USD is ~166 today, while $106 in 2016 USD is ~$130. Accounting for materials price increases you might argue that $130 is as such a fair price for a lower tier card today, though I'd still say $120 would be fair. The 6500 XT ought to be around $160-180.
W1zz needs to add a GT1030 to the list to compare this card too :)
Absolutely! That would be a very relevant comparison.
Frankly, does RX 6400 beat RX 550 or RX 560? 6500 XT actually failed to beat 5500 XT.
... did you look at the review? Both RX 550 and 560 are in the test results, and deliver ~32% and ~42% of the RX 6400's performance respectively at 1080p.


I forgot to say above, but thank you for a great review once again @W1zzard! Great to see these low end cards being tested, as that's somewhat rare. Still, I have to say I think your conclusion is a tad harsh - after all, you're running a test suite where everything is set at Ultra, which is notoriously inefficient. Most likely much better results can be had with near-imperceptible image quality drops in many games. Also, aren't locked-down OC controls the norm for slot-powered cards? I seem to remember that being pretty normal as a safeguard to avoid burning out the 12V traces in your motherboard.

That being said, there are two follow-up reviews that I would find very interesting in light of this: PCIe scaling to compare against the 6500 XT (testing the assumption that lower performance equals less of a bottleneck), as well as testing at lowered settings with the aim of finding what settings hit 60fps (or if it fails to) across the test suite at 1080p. Ideally the PCIe scaling test would also be run at non-ultra settings to account for this not being a realistic use case for this product. I completely undertstand this being a ton of work for a low-prestige product, but I at least would read the heck out of both of those reviews.
