how does the 7800 X3D perform in star Citizen? we are here finally to answer that question we're
comparing it to loads of CPUs today we've got some big questions to answer like does the 7950x3d
really make any sense compared to the 7800 x3d is it much better than the non-3dv cache versions of
am5 CPUs does it blow this 5800 X 3D out of the water and how does it scale at 4K we did a little
bit of 4K testing for those of you who like to see how that performs so loads of things really
interesting data some interesting things that I think have changed slightly with the game actually
and more and more and more and more let's get into it the test setups are all the descriptions so
check those out the main things to note is that it's 319.1 the live patch currently and we are
using 1080p as our resolution for all of it until we get the 4K testing because you can't really
learn anything if your GPU select so you have to lower the resolution to do CPU testing the results
for this testing are effectively split into two categories one this is where 3db Cash 3 helps and
ones where it doesn't help as much we'll start off with the ones where it does help so we're starting
off with Quantum travel now there's all sorts of CPUs let me just explain what we're looking
at here we've got at the top there the 7950x3d just the 3D V cash CCD so I've gone into the BIOS
turned off the CCD that doesn't have the cash so that effectively becomes a 7800 X 3D you'll see
that it effectively matches the 7800 STD as you'd expect the 7950 x3d result below that is the full
whack one we've also got the Intel 13700 KF and I have to tell you that it's not really a fair test
for the Intel chip in these tests because I'm on a ddr4 weatherboard I sold the ddr5 when I had
and what I found when I tested before is that it will improve with ddr5 especially as it's getting
faster and faster so you've got to give the Intel uh chip a little bit of extra wiggle them in your
mind because it would perform better than that with faster ddr5 wrap but the key thing to to
learn from this is again look at the 5800 xcd it will not perform this well in all of the tests but
with the 3db cache in quads of travel it seems to really help the same in space you've got the
top two results especially matching 7800 actually effectively matches the 79 50x3d when it's got the
v-cash turned off and again the 5800 xcd is doing really well and and so far you might look at that
and think well that isn't really worth the upgrade the X 3D 5800 x3d is doing really well you're not
seeing much benefit really but as I say that is going to change but on the origin roof is the
same story the 3D V cache seems to help all those chips there's not really any good reason why the
7800 X 3D is a bit further out front that's probably just runs around kind of variants
but when we move to these next few scenes you'll see the picture slightly changes still the 7950
XUV and the 7800x3d are doing really well they're still winning but if you notice now the 5800 xcd
has dropped below the 7700x and the 3700 KF and so there are certain scenes where it it seems as
though Star Citizen will really heavily utilize the vcash and there's certain ones where it
won't the good news for the am5 x3d parts is that they're still at the top of the charts even when
the scene doesn't really use the X3 V cash next the r core brand is the same story The 7950 XUV
and the 7800 XUV match as you kind of expect but again this isn't a scene that really utilizes V
cash so the 5800 x3d has really dropped down it's starting now to look like more of a good upgrade
from the 5800 x3d to these new x3d parts and to be honest even the 7700x is doing really well but
as we saw before it does lose out to the 5800 xcd in those earlier scenes and then in Louisville has
become increasingly hard to run the new update to it has made it really hard but we're still around
the 60 FPS Market which is really good news you'll see again that the 5800 xvd part has dropped way
down the list again signifying that this scene this run through Louisville doesn't really
heavily utilize the V cash I think that might be to do with the optimizations that cig have
made because in the past the 5800 STD would be the 3700 KF so I wonder if something has changed
and the the extra clock speed that the 7700x and the 13700k have is now maybe being better
utilized in in Louisville in particular and then for those of you who are often asking can we see
some high resolution as well I had enough time to do a bit of 4K you will see here effectively we've
lost a couple of phrases for the top results but they're not particularly GPU bottlenecks
still at 4K the 4080 that I'm using here is still powerful enough enough to basically outmatch these
CPUs which is a unique thing in games most of the time you are going to be GPU bought up to at 4K
but here still the CPUs are the main bottleneck and there are a couple of points around the room
where it does become GPU butter and that's why we've lost a couple of frames on average
um but there's not much scaling at 4K so what to makeable this let's answer some of those questions
from the start compared to the 7950x3d the 7800 actually is just a much better option for assassin
and gaming yes there will be some cases for some people who are doing work production stuff where
the more expensive 7950 xcd makes sense but for Star Citizen that just is not the case it
is just a waste of money and the whole thing we had when I first reviewed the 7950 xue that you
would turn off the non-seat the non-3dv cache CCV and it would perform better that's solved
at least I don't know where that would have been AMD Microsoft or cig but it seems as though it
makes no difference now to Performance whether you turn it on or off but again the 78 engine x3d is
just a much better option as at a much better price for the 5800 xcd it's an interesting one
because as we saw from the results there were some where it was pretty close and there was somewhere
it was much much slower so and so the 5800 X 3D is still a great upgrade option if you're on am4 it
does bring much better fallers than say the 3600 but if you're building a new system I Think It's
tricky to look past the 7800 xcd it is an absolute Beast there are issues with am5 we can't deny that
um I had a motherboard and Aces pretty expensive top of the line all the fantasy bits of the kind
of ddr5 the so the pcie5 stuff it just stopped working and it to be fair it hadn't been great
since I first got it there was issues with the BIOS I'd have to unplug uh USB things from the
back to get it to turn on it it had always been a bit of a nightwear My Hope was that with bios
updates it would improve but it's just given out so I've replaced that with a cheaper gigabyte
board and that's been completely Rock Solid but there have been issues with am5 there's been CPUs
overheating and kind of exploding um and so that obviously isn't good
that's kind of typical of amd's first generation when they're on a new platform there are often
issues it does tend to get sorted so I I would say we're getting to the point now where it's pretty
safe they've solved the overheating and exploding issue by reducing voltage and so I think we're
probably now getting to the point where they're a good safe Buy in terms of exploding and just
working well this new motherboard has been perfect for me so far I would say from a performance point
of view from a a lifetime upgrade path point of view the am5 CPUs are incredible for starters and
bet they are the best out there right now it's it's a great CPU the 7800 X 3D and it's going
to be my recommended CPU if you want the best performance in star system going forward [Music]
