play00:00

The story begins here, at Apple Park in  Cuppertino. Not where you would expect a story  

play00:05

about Qualcomm's Snapdragon X Elite to start.  But it's likely the very place where first ideas,  

play00:11

of what would much later become the CPU  cores of the X Elite, originated. Although  

play00:16

I have to be careful with my words, because this  question already started a lawsuit once before.

play00:21

When Apple created the original iPhone, a new  type of chip was needed to meet the demands of  

play00:26

a mobile phone with a large touchscreen.  Since Apple wasn't a chip design company,  

play00:31

they had to work with a 3rd party, and  they choose Samsung. Samsung designed and  

play00:36

manufactured the initial iPhone SoCs, which  combined ARM CPU cores with PowerVR graphics.

play00:42

But Apple wanted more control over their chips,  which is why they acquired Palo Alto Semiconductor  

play00:47

in 2008, better known as P. A. Semi, for $278  million. With the newly acquired chip design team,  

play00:55

Apple went right to work and designed  its first in-house SoC: the Apple A4.

play01:01

The A4 was very similar to the previous  chips designed by Samsung. It still used  

play01:06

Cortex CPU cores from ARM, PowerVR graphics and  Samsung continued to handle the manufacturing,  

play01:12

mostly in Samsungs FAB in Austin, Texas. Which  is especially relevant today, with all the talk  

play01:17

about bringing manufacturing back to the US.  Early iPhone SoCs were US designed and made.

play01:22

In 2010 Apple acquired another semiconductor  company, called Intrinsity and with it their  

play01:28

Fast14 electronic design automation software.  The acquisition of these EDA tools allowed Apple  

play01:34

to implement dynamic logic designs which  increased the performance characteristics  

play01:39

of their chip. Apple was quickly becoming a  fabless semiconductor company and after just  

play01:44

two generations of in-house SoCs, the Apple A6  ushered in a new era. For the first time ever,  

play01:51

Apple didn't license CPU cores from  ARM, but instead build a custom CPU,  

play01:56

code-named "Swift", based on a  modified ARMv7-A architecture.

play02:00

There are two ways to get access to a ARM based  CPU. The most common way is to directly license  

play02:05

one of the pre-build designs that ARM offers,  for example a Cortex CPU. But you can go one step  

play02:12

further and get a architecture license, which  allows you to build your own CPU, based on the  

play02:18

proprietary ARM instruction set architecture.  This type of license is more expensive,  

play02:23

but gives you more freedom and control. And Apple  did just that, they bought a architecture license  

play02:28

from ARM and the "Swift" cores inside the A6  were the result of this new design direction. And  

play02:33

before you ask - yes - this is still a video about  Qualcomm's Snapdragon X Elite. Just bare with me.

play02:39

The A6 was a inflection point for Apple  and jump started the domination of Apple  

play02:44

silicon in the years to come. Apple invested  heavily into their chip design department,  

play02:49

attracting and forming many of the world's top  ARM chip architects. With each new generation,  

play02:55

Apple silicon further increased  its lead over the competition.

play02:58

Building on that success, Apple started  to increase the scope of its SoC designs,  

play03:03

going from smartphone to laptops and eventually  desktop grade chips. I'm sure everyone watching  

play03:08

this video knows how big of a leap the Apple  M1 generation really was. Apple's ARM based  

play03:13

CPU architectures dominate not only in  performance, but also in efficiency.

play03:18

But chips aren't created out of thin air,  

play03:21

Apple had a lot of very talented engineers. And  while working for Apple certainly has its perks,  

play03:27

some of these engineers wanted to create more  complex designs, specifically server focused CPUs.

play03:32

In early 2019, a couple of former Apple chip  architects founded a company called Nuvia. Gerard  

play03:39

Williams, Nuvia's new CEO, was previously Senior  Director for Platform Architecture at Apple,  

play03:45

where he worked from 2010 up until he founded  Nuvia in 2019. He started working at Apple  

play03:51

just before the launch of the A4 and left  when the M1 design was already finished. He  

play03:56

was one of the major architects behind Apple's  entire CPU and SoC development for nine years.

play04:02

Manu Gulati, also a founder at Nuvia,  joined Apple in 2009 and was the lead  

play04:07

SoC architect starting with the A5X all the  way up to the A12X. He left Apple in 2017,  

play04:13

for a short two year stay at Google's SoC  department, before co-founding Nuvia. John Bruno,  

play04:19

the third co-founder, also worked at  Apple from 2012 to 2017 as a systems  

play04:25

architect. He also had a short one and half  year stay a Google before starting Nuvia.

play04:29

As you can see, all three Nuvia founders  were major players in Apple's silicon  

play04:33

journey and had extensive experience and  knowledge of how to design a world class  

play04:38

ARM architecture. Of course Nuvia had many more  talented employees aside of the three founders,  

play04:43

a lot of them with a Apple or ARM background.

play04:46

Apple didn't like that at all. Losing chip  design talent to a new startup hurts. And  

play04:51

Apple responded, with a lawsuit, alleging that  founder and CEO Gerad Williams was plotting  

play04:56

to form Nuvia and poach Apple talent while still  working at Cuppertino. A pretty serious allegation  

play05:02

but also very difficult to proof, especially  since California doesn't allow any kind of  

play05:06

non-compete contracts. This lawsuit continued  for over three years until it was dropped by  

play05:11

Apple in early 2023. By that time, Nuvia didn't  exist any more, but more on that in just a bit.

play05:17

Back at Nuvia, the engineers started  working on their first product,  

play05:20

a server grade SoC called "Orion" and  its custom ARM CPU core architecture,  

play05:26

code-named "Phoenix". Nuvia's goals  for Phoenix were very straight forward:  

play05:30

achieve the highest single-thread performance  and world class energy efficiency at the same  

play05:35

time. Very ambitious to say the least. But with  such a experienced team behind these claims,  

play05:40

the start-up money came pouring in. Nuvia raised  $53 million in its series A and $240 million in  

play05:47

a series B round. They had the talent and now  they also had the funding to achieve their goals.

play05:52

In August of 2020, Nuvia's John Bruno published an  article about Phoenix and shared early performance  

play05:58

indications. Compared to the competition,  which at the time included AMD's Zen 2,  

play06:02

Intel's Sunny Cove, Apple's A13 Bionic and  Qualcomms Snapdragon 865, Nuvia claimed that  

play06:08

its Phoenix architecture would be twice as  fast without increasing power consumption.  

play06:13

It's interesting that Nuvia compared a  server CPU with mobile and laptop chips,  

play06:17

but it didn't make these claims any  less impressive. Nuvia was on track  

play06:21

to deliver a world class CPU architecture  that might even be ahead of the competition.

play06:26

And then everything changed. In March  2021, just two years after it was founded,  

play06:32

Qualcomm bought Nuvia for $1.4 billion.  The goal of the acquisition? Implementing  

play06:37

Nuvias Phoenix CPU architecture into future  Snapdragon SoCs. And with the X Elite, that  

play06:43

future is finally here. Now you know why the  story of the X Elite begins in Cuppertino.

play06:48

I think it's important to know the backstory  of the X Elite, because it plays a major role  

play06:52

in why there's so much hype surrounding it.  Qualcomm already designs amazing CPU cores,  

play06:58

but with the acquisition of Nuvia and  the adoption of Phoenix into Snapdragon,  

play07:02

there's a real possibility to not only catch  up to Apple's M-chips in terms of performance  

play07:07

and efficiency, but to potentially outclass it.  The talent and experience is certainly there.

play07:13

But before we take a look at the hardware  of the Snapdragon X Elite and talk about  

play07:17

some of its mysteries, there's  another lawsuit to talk about,  

play07:21

that started right after Qualcomm bought Nuvia.  And no, it wasn't Apple this time - it was ARM.

play07:27

Now you might wonder why ARM would sue Qualcomm  and Nuvia, it's a head scratcher for sure. Just  

play07:32

like Apple, Nuvia had a ARM architecture license,  which allowed them to design their custom Phoenix  

play07:37

CPU cores. And the same is true for Qualcomm,  another long term ARM customer with a full  

play07:43

architecture license. ARM's reasoning is that  Nuvia was initially designing a CPU architecture  

play07:48

for servers, which is a much lower volume product  than the mobile SoCs Qualcomm is working on and  

play07:54

thus Nuvia had very different licensing terms.  The litigation is still ongoing at the moment.

play07:59

But enough about the origins  of the X Elite and lawsuits,  

play08:03

let's take a look at the hardware  you've been hearing so much about.

play08:06

The Snapdragon X Elite is a complete  system-on-a-chip, like previous Snapdragon  

play08:10

variants and combines CPU, GPU and NPU with MISC  areas like display engines, a 5G modem and of  

play08:17

course I/O. It's manufactured in a 4nm process  node, most likely TSMCs N4P and while we don't  

play08:24

have a official die-size, Semiaccurate reports  they have measured about 170 to 180mm², which  

play08:32

puts it in line with AMD's Phoenix (not the Nuvia  one), Intel's Meteor Lake-M and above Apple's M3,  

play08:40

which sits at sub 150mm². The new M4 chip that  Apple just announced might be pretty close  

play08:46

is size. The die-size of the X Elite leaves no  doubt, we are looking at a true laptop class SoC.

play08:52

The CPU inside the X Elite, code-named "Oryon"  with a "y", contains 12 cores divided into three  

play08:59

clusters with 4 cores each. The cores are based  on Nuvia's Phoenix architecture, tho I'm sure  

play09:05

some changes to the original vision have been made  since the acquisition, because a server focused  

play09:10

architecture has different design targets than  a low-power laptop SoC. The X Elite only has one  

play09:16

CPU core type and does not combine performance and  efficiency cores, like most other ARM based CPUs.  

play09:21

Knowing the story behind the X Elite, it does  make sense, because Nuvia's Phoenix was a single  

play09:26

performance core design and didn't include smaller  E-cores, that's why the X Elite only uses P-cores.

play09:32

Qualcomm didn't share much about the cache  system, other than the total size of 42MB,  

play09:37

most likely a combination of L2 and L3  cache. But we do know that the L2 cache  

play09:42

is shared between each 4-core CPU cluster,  since the lower tier Snapdragon X Plus,  

play09:47

which comes with two cores disabled, has the  same 42MB of cache. If the L2 cache would be  

play09:52

core exclusive, two less cores would result in  less cache, which clearly isn't the case here.

play09:58

The CPU cores clock between 3.4GHz for all-core  workloads and up to 4.2GHz for two cores on  

play10:05

the top end SKU. Last year, at the initial  reveal, Qualcomm talked about up to 4.3GHz,  

play10:11

which means the boost clock has  decreased by 100MHz since then,  

play10:14

indicating the yield wasn't good enough to  hit 4.3GHz on the required number of chips.

play10:20

The integrated Adreno GPU supports full DX12,  can reach up to 4.6 TFLOPS and according to  

play10:26

Qualcomm is outperforming AMD's Phoenix APU  by up to 80%. There's not much to add here,  

play10:32

we'll have to wait for independent  reviews to confirm these claims.

play10:35

Qualcomm shared a bit more on the integrated  Hexagon NPU that delivers up to 45 TOPS of INT8.  

play10:42

According to Qualcomm that's enough to locally  run the 13 billion parameter model of Llama 2,  

play10:47

which would be very cool indeed. And it  would be faster than the NPUs in Meteor Lake,  

play10:51

Phoenix and even Apple's M4,  tho Lunar Lake and AMD's Zen  

play10:56

5 APUs will likely catch up or even  outperform the X Elite in this area.

play11:01

Last, but certainly not least, there's the memory  system. Both the 12-core X Elite and it's little  

play11:06

brother, the 10-core X Plus, support LPDDR5X-8448.  And if that sounds like a strange number to you,  

play11:14

you are right. Last year, at the initial  preview, Qualcomm stated that the X Elite  

play11:19

would support LPDDR5X-8533, so we've got  another clock speed downgrade in addition the  

play11:25

drop in CPU boost. And while it certainly  won't have a big impact on performance,  

play11:29

it's another strange development. My guess is that  the memory controller wasn't good enough to handle  

play11:34

8533 MT/s and the downgrade to the strange number  of 8448 MT/s was made in order to increase yield.

play11:43

Looking at the specs of the X Elite we can  see all the ingredients that make a great SoC,  

play11:49

but at the same time we know very little about  the actual architecture. It's a 12-core CPU in  

play11:54

3 clusters with 4 cores each and 42MB of cache.  L2 and L3 cache seem to be shared. But there is  

play12:01

nothing more concrete about the actual CPU  architecture. How wide the CPU is, how many  

play12:06

stages, specific IPC numbers, boost behavior.  Qualcomm is keeping quiet. All performance  

play12:11

claims are either unvalidated, directly from  Qualcomm or from a very controlled environment.

play12:17

Then there is the reduction in CPU boost and  memory clocks compared to the reveal last year,  

play12:23

indication ongoing tweaks to the  yield. This isn't uncommon at all,  

play12:26

but running a odd memory configuration  like LPDDR5X-8448 is a bit strange.

play12:33

But the biggest mystery is the software.  Unlike Apple, Qualcomm doesn't control  

play12:38

both hard- and software. The Snapdragon  X Elite will run Windows for ARM and it  

play12:42

seems like Microsoft will have a exclusive  contract with Qualcomm for the Snapdragon X  

play12:47

line-up. Windows for ARM isn't new and every  previous attempt has failed. It's not only  

play12:52

the lack of a wide range of supported apps,  but performance was also subpar in the past.

play12:58

And that's why I'm still not sure about Qualcomms  performance claims for the X Elite. I have  

play13:02

no doubt that the CPU architecture initially  developed by Nuvia is a world class design with  

play13:08

the potential to rival or even outclass Apple. But  I'm doubtful about Microsoft's ability to optimize  

play13:14

Windows for ARM in such a way that the X Elite can  actually use all of that performance potential.

play13:20

And we can't forget the competition. When  Qualcomm announced the X Elite last year,  

play13:24

they compared it to Intel's Meteor Lake,  AMD's Phoenix and Apple's M2. But that  

play13:29

won't be its competition. Instead, the X Elite  will have to compete with Intel's Lunar Lake,  

play13:33

combining Lion Cove and Skymont CPU  cores on TSMCs N3B, AMD is close to  

play13:39

launch it's Zen 5 Strix Point APUs and Apple  just announced the M4 produced in TSMCs new  

play13:44

N3E node. The competition this year will  be a lot stronger than it was last year.

play13:49

There are many reasons to be hyped  about Qualcomms next-gen laptop SoC,

especially considering the exciting history of  the chips development. But at the same time,  

play13:58

being so close to the official  launch, we still know very little

I'm hoping the Snapdragon X Elite will live up to  the hype and finally make Windows on ARM a viable  

play14:10

option, there's nothing better than competition.  And I'm looking forward for more in-depth  

play14:14

information about its architecture and the actual  silicon. Let me know if you would be interested  

play14:19

in a detailed comparison between the X Elite and  the M4, if I can get my hands on actual die-shots.

I would like to know your thoughts on the X Elite.  Do you think that the Nuvia team will be able to  

play14:29

deliver what they promised, or will the chip  be gimped by Windows? And if it performs well,  

play14:35

could you imagine switching to Windows for  ARM? Let me know in the comments below!

I hope you found this video interesting  and see you in the next one.
