today i pit the runt of amd's litter the rx 6400 against 8k gaming
for some reason and step number one was to go and get some 8k
so we went out and bought the cheapest 8k display we could find but before anna hello helps me unbox
this behemoth it's time for a quick word from today's video sponsor that helped pay for this
very sensible test today's video sponsor is back due to popular demand and it's none other than
lenode lenode is a linux based cloud computing and web hosting service that offers multiple products
to manage cloud storage websites databases game servers kubernetes and they can even

should lenode is one of the best in the business i mean look at how happy these two are with their
service if all of this sounds good to you sign up to lenode using the link in my description
below to get a 60 day hundred dollar free credit thank you lenode for sponsoring today's video
oh
i'm not sure but i think that this shouldn't be exposed to babies
wow that is a big ass tv now this huge tv is the lg 65 nano 95 which has a 65 inch ips
display and yeah there's a whole bunch of lg marketing crap around its hdrness and whatever
but i think by far the most interesting thing about this tv is that at a thousand five hundred
canadian dollars it is the cheapest way to get your hands on a native 8k panel and i am really
excited to see what that little rx 6400 is going to make of this tv now to put into perspective
just how trouser soiling the prospect of 8k gaming is even for a high-end graphics card
if this square represents the pixels in a 1080p image a resolution that let's face it already
kind of pushes the limits of what the rx 6400 can do this is what 8k looks like in fact you can fit
16 1080p images in one 8k image which for the tiny little die of the rx 6400 and its 4 gigs of
video memory may be a bit of a challenge although interestingly one of the things that makes the rx
6400 potentially usable for 8k gaming is that it has an hdmi 2.1 port which means it should be able
to output an 8k signal so let's drop the little rx 6400 in a gaming pc so that we can put a chihuahua
against cthulhu and see what happens ah yes i think the rgb vomitron is the perfect host for
our 6400 8k test this rgb gpu support bracket is really putting in some work with the 6400
let's see what output resolution we have here 4k that's that's as high as it's letting us go
luckily getting the tv to output an 8k signal only took a couple of minutes first i reinstalled the
graphics card drivers and then i had to switch the hdmi output from 4k to 8k in the tv settings
yes there we go that is a nice number to see it's funny that it recommends we not
use the native resolution of the display but let's see what happens when we do is that an 8k now it
was and i was very impressed oh yes there is some resolution right there and would you look at that
the fabled tiny little 8k msi afterburner makes its long-awaited return to the channel like you
can go right up to things and it it still looks very very sharp but again we're not here to marvel
at 8k we're here to punish a little baby graphics card with it so let's try and run some games
now we're going to start off with gta 5 running at 1080p with everything on the lowest settings
available and we are getting a very good result look at that over frames 180fps second wow it
is actually running too well because it's at that point with gta 5 where you start getting stutters
because the engine can't handle the very high frame rate so we definitely need to move up to 4k
that is much better than i was expecting we are getting solidly over 60 frames per second at 4k
with the little 6400 granted this is with all low settings but i am still very impressed by that it
is really playable okay so if it runs 4k this well then 8k is not going to be a problem at all is it
wow that has dropped from 70 frames per second at 4k down to 4 frames per second at 8 games
this is exactly the kind of gpu carnage i was looking for the 4k result had me worried but
8k really has delivered here but let's see if we can find a game the 6400 will run in 8k
okay now we are gonna have to do a bot match because otherwise we won't have an overlay
so with 1080p low settings cs go is giving us a reasonably high frame rate although it's
not that much higher than uh gta 5 so i don't actually have very high hopes for the 8k result
oh it doesn't like 4k very much there's quite a bit of tearing and there's the occasional visual
artifact let's actually see oh we have eight times anti-aliasing running that is not what you want to
be doing running at 4k so let's disable all of this stuff ah ah yes cs go has in fact crashed
oh no we're back it just had a bit of a tactical crash just to recover and now
we're we're good despite the high frame rate it's actually not that good a gaming
experience the image is very teary and you can really feel the input lag let's see 8k
there we go and 8k apply oh it does haven't it oh oh it does not like 8k on csgo that just took the
system straight down that is quite a unique blue screen of death as well i don't think i've seen
four of them on one display okay i guess cs goes out of the question
whoa look at the size of the cursor in dota it's like basically the size
of my so with dota 1080p highest settings we're getting about 200 frames per second
uh so let's immediately just very quickly
i wouldn't be surprised if dota 2 would run on an easy bake oven
because we're getting almost 24 frames per second at 8k with an rx 6400 now don't get
me wrong this is by no means a usable result and if you enter a ranked game with this kind
of performance you're full-on griefing but still that's that's kind of crazy
now we may just be in a corridor here but of course half-life 2 at 1080p high settings
runs crazy well on this system because well it's not a casio watch but let's let's make it a little
bit more daunting just immediately off the bat with 4k it had zero impact on the frame rate
even coming outside we're still running at a solid 300 ish frames per second so yeah let's jump to 8k
they clearly did not foresee the half-life 2 title being displayed in 8k ever look at that
i like how the scaling just completely falls apart at 8k it does not even almost know what to do with
itself here but once i loaded into the game i was genuinely blown away the complete lack of jaggies
is the thing that really gets me about it native 8k is actually kind of wild you can clearly tell
that the textures and stuff were not made with 8k in mind but you get right up to the image and
it's just so crisp i'm so impressed with how well half-life 2 scales with crazy high resolutions of
course when you get close up to the textures you can see that they don't look fantastic but
something about the resolution just makes the old graphics look weirdly real and look at how well
it's running like if this tv could display 120 hertz 8k we'd be able to game with high
refresh rate 8k on an rx 6400 granted the game is almost 20 years old at this point but still
this makes me really want to do a video with dynamic super resolution in this tv to see if
we can use half-life 2 to bring a 30-90 ti to its knees i think that would be pretty cool and just
like that i was hooked to the uncanny appeal of super high resolution gaming i was trying every
old game in my steam library that i thought would work on the system and i was blown away every time
the impeccable sharpness of the high resolution gives this uncanny realism to the bad graphics
that makes it seem more like you're seeing in bad graphics than playing a game that has bad
graphics if that makes sense and anna was really impressed with the size of it and
and it's kind of because of its size that i think that like i feel like i could be walking
into this doorway yeah like would be that size i feel like if i was running upstairs
they would be that size it's like the scale of the image is lifelike
yeah yes i think it's that so what started out as an exercise in gpu torture ended up getting
me really excited about old video games which i think is a good point to end off this video if you
