WEBVTT

00:00:00.000 --> 00:00:06.060
the ryzen 7 7800x3d is the best gaming

00:00:03.360 --> 00:00:09.780
CPU on the planet Bar None it isn't even close

00:00:07.020 --> 00:00:15.240
I should be celebrating then yeah so why do I look so mad because as far as I can

00:00:12.660 --> 00:00:20.039
tell AMD intentionally manipulated the community in the lead-up to this launch

00:00:16.920 --> 00:00:23.340
first they pushed their most rabid fans

00:00:20.039 --> 00:00:27.060
to more expensive and arguably worse

00:00:23.340 --> 00:00:28.680
ryzen 9 x 3D CPUs at launch although

00:00:27.060 --> 00:00:35.219
that's nothing new and all the major players have done this at one time or another but the second one is much more

00:00:32.820 --> 00:00:40.079
nefarious and reminds me of the way that Intel timed the release of their 10th

00:00:37.620 --> 00:00:44.940
gen hddt processors in a way that avoided direct comparisons to AMD's far

00:00:42.300 --> 00:00:49.500
superior threadripper 3000 it's yucky and I'm gonna spell out why it's such a

00:00:47.040 --> 00:00:54.059
problem shortly first I need to spell out why AMD now makes the only gaming

00:00:51.960 --> 00:00:59.699
CPUs that matter and I need to spell out this s-e-g-u-e to our sponsor gizmogo

00:01:08.340 --> 00:01:16.619
below it's been almost a year since AMD launched their first processor featuring

00:01:12.479 --> 00:01:18.840
3D vcash technology the ryzen 7 5800 X

00:01:16.619 --> 00:01:23.580
3D and to say that it's been a game changer would be both an understatement

00:01:20.759 --> 00:01:29.580
and a delightfully delicious dad joke the details are complex but the result

00:01:25.860 --> 00:01:31.380
is simple 3D vcache allows AMD to stack

00:01:29.580 --> 00:01:36.299
up the caches in their processors vertically increasing their capacity

00:01:33.720 --> 00:01:40.920
without increasing the die area of the finished chip a larger cache means that

00:01:38.820 --> 00:01:45.060
any data the processor needs is more likely to be right at hand rather than

00:01:43.020 --> 00:01:50.340
stored in much slower system memory or heaven forbid persistent storage like an

00:01:47.700 --> 00:01:55.200
SSD there are trade-offs reading between the lines 3D V cache has some downsides

00:01:53.040 --> 00:01:59.460
it appears to be much more sensitive to high voltages which makes overclocking a

00:01:57.600 --> 00:02:04.320
less fruitful not to mention riskier Endeavor and has forced AMD to reduce

00:02:01.979 --> 00:02:07.979
their out-of-the-box clock speeds it also reduces the rate at which heat can

00:02:06.119 --> 00:02:12.840
be dissipated from the course meaning that 3D V cache chips have their thermal

00:02:09.899 --> 00:02:17.459
targets reigned in but it seems to be worth it because while AMD's slide deck

00:02:15.060 --> 00:02:22.980
has the 7800x 3D competing with the core i7 13700k in terms of pricing if we

00:02:20.819 --> 00:02:28.319
consider quite literally anything else it is not even a contest especially in

00:02:26.700 --> 00:02:33.480
gaming where it makes such a difference to Performance that well I'll just let

00:02:30.480 --> 00:02:36.780
the graphs do the talking here look at

00:02:33.480 --> 00:02:39.239
these margins of Victory dang

00:02:36.780 --> 00:02:42.660
I mean if you like spending a hundred dollars more for Less performance from

00:02:41.160 --> 00:02:46.800
Team blue then that's kind of your prerogative but if you're the sort of

00:02:44.700 --> 00:02:50.459
gamer looking to drive the latest 1080p High refresh rate monitors the only

00:02:48.780 --> 00:02:56.160
sensible choices we're looking at here are the 5800x 3D on a cheap and cheerful

00:02:53.819 --> 00:03:00.319
am4 board with 16 gigs of memory for another 50 bucks or if you've got the

00:02:58.440 --> 00:03:06.360
extra cash to put into a newer platform AMD's 7800x 3D absolutely obliterates

00:03:04.379 --> 00:03:11.099
everything in its weight class I mean even its own x3d equipped Bigger

00:03:08.700 --> 00:03:16.500
Brothers fall considerably behind which raises some big questions like what the

00:03:14.220 --> 00:03:21.959
and why Paulo kohilo said that the core of

00:03:19.440 --> 00:03:27.300
beauty is Simplicity and I think that applies well here the 7800x 3D comes

00:03:24.780 --> 00:03:32.700
equipped with a mere 8 course on a single core complex die or CCD that

00:03:30.420 --> 00:03:38.099
means virtually all applications will benefit from its whopping 104 megabytes

00:03:35.580 --> 00:03:43.379
of on-die cache and since there's only one CCD there's no latency penalty from

00:03:41.159 --> 00:03:52.019
pulling cached data off of another die by contrast the 7900x3d and the 7950x3d

00:03:48.900 --> 00:03:56.220
have 12 cores and 16 cores respectively

00:03:52.019 --> 00:03:58.019
across two heterogeneous ccds AMD's

00:03:56.220 --> 00:04:02.700
rationale for the design Choice does make sense half of the cores get 3D V

00:04:00.659 --> 00:04:06.959
cash for killer gaming performance while the other half issue it in favor of

00:04:04.680 --> 00:04:11.760
higher yields and higher boost clocks for productivity but in practice getting

00:04:09.480 --> 00:04:16.019
applications to run on the most optimal core is a big challenge especially when

00:04:14.580 --> 00:04:20.579
you don't bother to build an on-chip Hardware sketch or load balancer and it

00:04:18.660 --> 00:04:26.699
results in lower real world performance that puts the ryzen 9x3d chips in this

00:04:24.120 --> 00:04:31.500
super weird in-between Zone where they fall behind their lean mean ryzen 7

00:04:29.100 --> 00:04:37.740
relative in gaming and then fall behind their own non-x3d counterparts in other

00:04:34.500 --> 00:04:40.020
applications of course as we pointed out

00:04:37.740 --> 00:04:47.280
in our review of those chips most people aren't buying 500 CPUs or even 350 ones

00:04:44.699 --> 00:04:53.759
for that matter to game at 1080P and if the 7800x 3D can't keep its lead going

00:04:49.620 --> 00:04:56.460
into 1440p I think oh it does looking at

00:04:53.759 --> 00:05:01.380
average frame rates the 7800x3d tops the charts almost without exception only

00:04:58.860 --> 00:05:06.000
losing in games where Intel CPUs tend to provide improvements in one percent lows

00:05:03.240 --> 00:05:11.280
even games that are clearly GPU Bound in our testing like Modern Warfare 2 and

00:05:08.220 --> 00:05:14.340
Red Dead Redemption 2 see the 7800x3d

00:05:11.280 --> 00:05:17.220
generally eke out a small W there are

00:05:14.340 --> 00:05:20.880
exceptions occasionally even gay won't benefit from 3D V cash and would just

00:05:19.259 --> 00:05:25.139
much rather have a CPU that boosts higher but the overall picture is clear

00:05:22.979 --> 00:05:30.060
to the point where I'm not sure I remember ever seeing anything quite like

00:05:27.360 --> 00:05:35.580
this I mean the thing is for you the viewer watching this 10 FPS here five

00:05:33.360 --> 00:05:39.660
percent difference there it might not seem like that big of a deal I don't

00:05:37.440 --> 00:05:44.160
even play those games you might say but that isn't the point our test Suite

00:05:42.300 --> 00:05:47.759
is designed to guide you toward the product that will provide the best

00:05:45.539 --> 00:05:52.680
long-term value not just in games today but in games in the future and that five

00:05:50.400 --> 00:05:58.139
percent today can easily turn into eight percent tomorrow or 15 a few years from

00:05:55.680 --> 00:06:02.820
now when faster gpus arrive and need more powerful CPUs to perform their best

00:06:00.960 --> 00:06:07.440
here's an edge case that illustrates my point very well factorio's unit

00:06:05.400 --> 00:06:12.780
simulation update rate is capped in game to 60 per second that means that any one

00:06:10.620 --> 00:06:18.180
of our CPUs is going to deliver a peak optimal experience in this game

00:06:15.720 --> 00:06:22.380
but by forcing the game's engine to push Beyond these artificial limits we can at

00:06:20.520 --> 00:06:27.180
least attempt to draw conclusions about the benefits we might enjoy in future

00:06:24.600 --> 00:06:31.800
Sim heavy games if we choose the right Hardware today and the right choice

00:06:29.580 --> 00:06:35.940
isn't always obvious from the manufacturer's marketing you might

00:06:33.840 --> 00:06:41.100
quickly skim a headline or two and go oh okay 3D V cache is great I'll just get

00:06:38.460 --> 00:06:46.080
the best one with that but as you can see when we force factorio to run on the

00:06:43.620 --> 00:06:51.000
3D V cache cores by disabling the other ones it performs right neck and neck

00:06:48.360 --> 00:06:55.020
with the 7800x 3D but when we leave it at default with all the cores enabled it

00:06:53.160 --> 00:07:00.479
falls way back in line with the rest of the pack pretty questionable behavior

00:06:57.240 --> 00:07:02.660
for a gaming CPU don't you think and

00:07:00.479 --> 00:07:08.699
pretty questionable behavior from AMD when they split up the launch of the

00:07:05.280 --> 00:07:10.560
7000 X 3D product line I believed that

00:07:08.699 --> 00:07:14.280
they simply wanted to capitalize on early adopters who were willing to pay

00:07:12.419 --> 00:07:19.919
for more cores than they needed in order to get the latest shiny 3 3db cash chips

00:07:16.919 --> 00:07:21.599
I mean why play an ace if a tool do it's

00:07:19.919 --> 00:07:25.740
not an unusual strategy and is absolutely the reason that NVIDIA slow

00:07:23.759 --> 00:07:31.259
rolls their product lineups top to bottom over time but the thing NVIDIA

00:07:27.900 --> 00:07:34.020
doesn't do is launch a 4090 at Halo tier

00:07:31.259 --> 00:07:38.280
pricing only for buyers to end up ticked off when the 4070 arrives a few months

00:07:36.300 --> 00:07:42.900
later and is not only cheaper but actually performs better in games and it

00:07:41.220 --> 00:07:47.759
wouldn't have bothered me so much if AMD had seated review samples of the chips

00:07:45.060 --> 00:07:51.419
at the same time then simply staggered availability like we did with our

00:07:49.979 --> 00:07:58.500
screwdriver that is now live shipping on ltdstore.com but by splitting up the launches they

00:07:56.400 --> 00:08:04.139
created an environment where users who are seeking a review today of the ryzen

00:08:01.500 --> 00:08:09.419
9 x 3D chips are going to find countless articles comparing against Intel 13th

00:08:06.419 --> 00:08:12.720
gen but very few comparing against the

00:08:09.419 --> 00:08:15.539
cheaper Superior gaming product in AMD's

00:08:12.720 --> 00:08:18.900
own lineup now I doubt this strategy will make any kind of material

00:08:16.800 --> 00:08:22.800
difference to their sales in spite of Intel jumping a day ahead of AMD's

00:08:20.699 --> 00:08:27.599
release 10th gen core I9 was a sales disaster but I just don't like being

00:08:25.319 --> 00:08:31.020
played and I feel a little played right now though of course there is the

00:08:29.699 --> 00:08:35.399
argument that none of this matters Anyway by the time you get into Ultra HD

00:08:33.240 --> 00:08:39.479
gaming which is likely where many of those ryzen 9s are headed we didn't test

00:08:37.680 --> 00:08:43.440
as many games at this resolution since there's only so many times you can try

00:08:41.099 --> 00:08:47.399
to split the same hair but the bottom line is that the worst we're looking at

00:08:45.420 --> 00:08:53.700
across the entire range of chips we tested is about six to seven percent

00:08:50.120 --> 00:08:56.760
however that is due to the Mass massive

00:08:53.700 --> 00:08:58.860
20 range in F1 2022

00:08:56.760 --> 00:09:04.380
if you're the kind of gamer then who prefers High Fidelity experiences over a

00:09:01.680 --> 00:09:08.640
Competitive Edge then GPU bound games like cyberpunk and Shadow of the Tomb

00:09:06.540 --> 00:09:12.839
Raider you're just not gonna notice a difference and the same is true in our

00:09:10.800 --> 00:09:18.420
Ray Trace 4K games where the difference is even smaller I'm still a bit

00:09:15.360 --> 00:09:20.880
irritated it is kind of my job because I

00:09:18.420 --> 00:09:25.380
could make that exact same well it doesn't really matter anyway argument

00:09:22.380 --> 00:09:27.360
about the ryzen 9 x 3D chips as I move

00:09:25.380 --> 00:09:32.040
into our productivity results if a few percent FPS here and there

00:09:29.700 --> 00:09:36.480
doesn't matter to you in games well then you still should be paying the premium

00:09:34.140 --> 00:09:41.519
for these x3d chips because you would still be more than happy gaming on the

00:09:38.399 --> 00:09:43.740
regular X variants for cheaper and those

00:09:41.519 --> 00:09:49.140
non-3d chips will perform anywhere from about the same as their x3d equivalents

00:09:46.320 --> 00:09:52.860
to even better outside of games sorry this has gotten a bit derailed the

00:09:50.940 --> 00:09:58.019
video is supposed to be about the 7800x 3D and as you see on all of these charts

00:09:55.560 --> 00:10:02.959
it isn't a top performer here but we never expected it to be though it did

00:10:00.480 --> 00:10:08.700
Crush another metric that we did expect in our review of the ryzen 9 x 3D chips

00:10:06.360 --> 00:10:12.660
we took issue with AMD's marketing they called them gaming CPUs but we felt that

00:10:11.100 --> 00:10:18.300
their strength was actually in their efficiency and we are seeing the exact

00:10:15.060 --> 00:10:20.880
same thing here except that it is also a

00:10:18.300 --> 00:10:25.620
standout gaming value I know that the average gamer doesn't salivate over

00:10:22.860 --> 00:10:30.720
better performance per watt but this chip is so exceptional that I gotta slow

00:10:28.019 --> 00:10:36.480
you down and talk through this if you game two hours a day in California your

00:10:33.360 --> 00:10:39.860
7800 X 3D is going to cost you about 750

00:10:36.480 --> 00:10:43.200
a year to run for context AMD's closest

00:10:39.860 --> 00:10:47.220
non-x3d the 7700x is gonna cost you more

00:10:43.200 --> 00:10:50.220
like 950 and an Intel 13600k about nine

00:10:47.220 --> 00:10:53.040
dollars now watch this let's add an hour

00:10:50.220 --> 00:10:58.339
a day of video encoding or 3D rendering some other heavy load then let's assume

00:10:55.800 --> 00:11:04.800
a five-year lifespan for this system and holy crap the total cost of ownership

00:11:02.100 --> 00:11:09.120
goes from a boring metric for data center Architects to a serious

00:11:06.899 --> 00:11:13.079
consideration for enthusiasts and Gamers especially if they live in a region

00:11:10.920 --> 00:11:17.880
where energy costs are spiraling out of control like in the UK of course though

00:11:15.839 --> 00:11:21.779
value over time isn't the only consideration when specing out a new pc

00:11:19.560 --> 00:11:25.800
how much is this thing costing me today Linus

00:11:22.920 --> 00:11:29.820
less than you'd think at launch amb's am5 platform took a lot of flack for

00:11:28.200 --> 00:11:35.399
being poorly positioned compared to Intel's relatively inexpensive LGA 1700

00:11:32.880 --> 00:11:40.079
socket they did have the benefit of a supposedly longer support roadmap but

00:11:37.440 --> 00:11:45.019
AMD's record on that is imperfect these days at best and the chips the RAM and

00:11:42.959 --> 00:11:49.560
the motherboards were very expensive nowadays though the story is quite

00:11:47.160 --> 00:11:54.720
different a solid b650 board is going to run you around 200 US dollars 16 gigs of

00:11:52.320 --> 00:11:59.880
high-speed ddr5 will set you back under a hundred and the fastest gaming chip on

00:11:57.360 --> 00:12:04.620
the Block the 7800x 3D is going to cost you 450 bucks throw in a GPU and some

00:12:03.240 --> 00:12:09.420
other bits and Bobs and you're looking at an absolutely killer machine for less

00:12:07.680 --> 00:12:14.279
than fifteen hundred dollars still not cheap but if you want to save

00:12:11.459 --> 00:12:18.660
a buck the 5800 X 3D is still out there for a hundred dollars less and the

00:12:16.140 --> 00:12:22.800
market is flooded with dirt cheap am4 motherboards and ddr4 memory

00:12:20.940 --> 00:12:26.160
I wouldn't say then that Intel is down for the count but they do need to

00:12:24.540 --> 00:12:31.320
counter hard or it's going to be hard to come up with a reason to build blue that

00:12:28.320 --> 00:12:33.660
is at least for now almost as hard as a

00:12:31.320 --> 00:12:37.140
