00:00:00,000 --> 00:00:06,080
The Ryzen 7 5800X3D is supposedly one of the best gaming processors on the market,

2
00:00:06,080 --> 00:00:11,280
but is that 3D on the end just a marketing gimmick to remind you of the superior way of

3
00:00:11,280 --> 00:00:16,960
watching movies? Or is there actual truth to it? That was a joke, 3D movies suck.

4
00:00:16,960 --> 00:00:24,560
But this 3D does not. The 3D actually refers to a feature that AMD calls 3DVcash, with V standing

5
00:00:24,560 --> 00:00:31,040
for vertical, and 3D implying that the cash actually is stacked on the CPU die to make it, you know,

6
00:00:31,600 --> 00:00:38,320
three-dimensional. So it's not false advertising, even if technically you could label every processor

7
00:00:38,320 --> 00:00:42,560
3D since our universe does in fact have three dimensions, but let's not get pedantic.

8
00:00:42,560 --> 00:00:50,480
Okay, so 3DVcash is CPUcash stacked vertically. But what is CPUcash? Well, it's basically just

9
00:00:50,480 --> 00:00:56,080
a small amount of very fast memory, like way faster than your system RAM, that sits on the

10
00:00:56,080 --> 00:01:02,080
CPU itself. Modern CPUs move information that is likely to be needed soon into the cash,

11
00:01:02,080 --> 00:01:06,000
so by the time they actually need that information, it's sitting right there for them to go ahead

12
00:01:06,000 --> 00:01:11,280
and act upon instead of having to wait for it to arrive from system RAM. So it's not hard to figure

13
00:01:11,280 --> 00:01:17,200
out that having more cash equals better, but slapping more onto a chip is actually fairly

14
00:01:17,200 --> 00:01:22,400
difficult. As transistor sizes have gotten smaller, manufacturing has gotten more difficult

15
00:01:22,400 --> 00:01:27,920
and more expensive. It's actually not uncommon for cash to use an older process node than the

16
00:01:27,920 --> 00:01:33,680
CPU cores do. So instead of trying to shrink the cash transistors down to cram more of them onto the

17
00:01:33,680 --> 00:01:41,280
CPU die, AMD decided to just build up instead and stack several layers of cash on top of each other,

18
00:01:41,280 --> 00:01:47,840
hence the name 3DVcash. But how much does having a cash sandwich in your PC actually make a difference

19
00:01:47,840 --> 00:01:55,360
in the programs you use the most? AMD markets the 5800X3D, the only consumer chip featuring 3DVcash

20
00:01:55,360 --> 00:02:00,560
at the time we wrote this video, as a gaming powerhouse. And it does turn out that having

21
00:02:00,560 --> 00:02:06,160
additional CPUcash makes a significant difference in gaming performance. Having more cash space

22
00:02:06,160 --> 00:02:10,880
means that the graphics card doesn't have to wait around as long for data from the CPU.

23
00:02:10,880 --> 00:02:16,400
Without that additional cash, your CPU needs to go back and grab data from your RAM more often,

24
00:02:16,400 --> 00:02:21,680
which takes time and leaves your CPU frustrated and exhausted, wondering why its creators didn't

25
00:02:21,680 --> 00:02:26,480
give it more cash when they dumped it into this cruel world. Indeed, benchmarks have consistently

26
00:02:26,480 --> 00:02:31,760
shown performance benefits across the board compared to both AMD and Intel chips that don't

27
00:02:31,760 --> 00:02:36,880
utilize vertical cash. And it's not surprising considering just how much more you can add

28
00:02:36,880 --> 00:02:42,800
by building vertically instead of horizontally. While the original 5800X contained 32 megabytes

29
00:02:42,800 --> 00:02:50,960
of level 3 cash, the 5800X3D increases that number to a whopping 96 megabytes. Wowie, zowie.

30
00:02:50,960 --> 00:02:55,200
Of course, this kind of cash design comes with its own costs. And we're not talking about the

31
00:02:55,200 --> 00:03:01,440
premium you pay for the CPU either. Vertical cash does require extra power and it generates more

32
00:03:01,440 --> 00:03:06,080
heat. And although AMD has done a pretty good job mitigating these issues, partly by packing

33
00:03:06,080 --> 00:03:13,200
the cash layers as close together as possible, the 5800X3D does not officially support multiplier

34
00:03:13,200 --> 00:03:19,040
overclocking as the cash and the CPU cores actually share voltage. So you can't change one

35
00:03:19,040 --> 00:03:23,760
without affecting the other. This also means boost clocks are lower than chips with more

36
00:03:23,760 --> 00:03:28,640
traditional cash. So while gaming performance is often better depending on exactly which game it

37
00:03:28,640 --> 00:03:33,760
is you're playing, other chips with more cores and higher clock speeds are still superior for

38
00:03:33,760 --> 00:03:40,240
other tasks. But if you do mostly use your PC for gaming, there's exciting news in that more

39
00:03:40,240 --> 00:03:46,800
chips using 3D Vcash are on their way as additions to the Ryzen 7000 series. And over in serverland,

40
00:03:46,800 --> 00:03:51,680
there are AMD Epic chips featuring the technology since server CPUs have to move

41
00:03:51,680 --> 00:03:57,920
so much data that a bigger cash can be beneficial. However, it's yet to be seen whether Intel answers

42
00:03:57,920 --> 00:04:02,960
with a similar strategy. Right now, Team Blue seems to be sticking to consistently high boost

43
00:04:03,440 --> 00:04:07,360
clocks instead. But you have to admit, there's something elegant about stacking chips like

44
00:04:07,360 --> 00:04:12,080
a can of Pringles. Truly a snack for the elite. They're not sponsoring us, why am I? And even
