Also keep in mind that, with a 4.2 GHz CPU, electricity can only travel ±3.5cm during a single cycle. Factor for the time demanded by capacitance and latency, and you're lucky to traverse a single cm during a complete processor cycle. The AMD Zen 3 8-core die is 1.29 x 0.964 cm, with the shared 0.7cm² cache flanked by 0.3cm-wide CPU cores - keeping most operations within 0.6cm in order to obtain reliable operations at the rated 4.7GHz boost speed.
Prior to ±2000, CPU clock speeds were doubling roughly every 2-3 years:
~ 1982 : (1.5 μm) 80286 @ 6 MHz; 68000 @ 8 MHz
~ 1985 : (1.5 μm) 80386 @ 12 MHz; 68020 @ 16 MHz
~ 1989 : (1.0 μm) 80486 @ 25 MHz; 68040 @ 30 MHz
~ 1993 : (800 nm) Pentium @ 60 MHz; 68060 @ 55 MHz
~ 1995 : (500 nm) Pentium Pro @ 120 MHz; PowerPC 603/604 @ 120 MHz
~ 1997 : (350 nm) Pentium II @ 260 MHz; PowerPC 750 @ 260 MHz
~ 1999 : (250 nm) Pentium III, Athlon, PowerPC 7400 @ 600 MHz
~ 2001 : (180 nm) Pentium 4, Athlon XP @ 1.2 GHz
~ 2005 : (90 nm) Pentium D, Athlon 64 X2 @ 2.4 GHz
By 2005, CPU manufacturers were already approaching the physical limits of semiconductor technology and it took roughly a decade to refine manufacturing sufficiently (down to 32-10 nm; 7 nm for Zen2/3) to reliably deliver ±4.8 GHz on consumer-grade CPUs.

I'm old enough to remember Intel Pentium 2s looking like SNES cartridges.
Still have one lying around.
But the size of the CPU was almost the same as the modern ones. Everything else was the board and the cooler.
The actual CPU is that postage stamp size chip inside that SNES like cartridge. (The other chip was off die cache.)
That was my first CPU and I thought it looked cool and unique, more than today's ones.
I was actually wondering about this exact topic a few days ago. Didn't even google it or say it loud (you know Google's love for their users' microphones) and here it is. Thanks guys!

@@nxx99 his reply made no sense, that’s what my “?” was for..
@@fuzzydark1395 I know what he meant, the comment's grammar was just busted.
Part of the problem is the speed of light (or actually, the speed of propagation of electricity in silicon, which is some significant fraction of the speed of light). At 4 GHz, light can only travel about 7.5 cm. A processor can be thought of as a maze of tiny wires (obviously, a massive simplification), so in each clock cycle, the signal can only zig zag through up to 7.5 cm of that maze. The "maze" is folded in on itself, so the signal doesn't just go from one end of the chip directly to the other. So the larger you make your chip, the longer it takes for a signal to get from one side to the other.

@@jediael9906 Hey even other engines have this problem. Don't touch my bae S85b50
Great video thanks, I always wondered about that.
i have been pioneering for multicore development, early intel core duo adopter, and programming a multiprocessor server in 2005 that did cost around 10 cars.
We got a lot of architectures since that - offloading tasks to GPUs, TPUs, FPGA....
I was happy to see the bit.LITTLE architecture, and i was expecting to see something similar in the Desktop/Server Environment, but that did not hit the market.
What i would really need as a programmer, is something like a small 4-Core CPU optimizied for clock speed - so i have something fast that coordinates the others, additional worker cores, similiar to ARM Ampere - a lot of slow ticking core to pick up the heavy loads.
However, this might be tough to program to sync the locks between those CPUs...
I haven't programmed Ampere yet, but i see it as very challenging to have only one slow core running the main thread, that needs to coordinate the rest of the cores.
Ha, I asked that question so many times to myself.
I know these shorts videos are supposed to be kinda of like a crash course on a topic, but IMO this one creates a lot of unnecessary confusion. The video can't seem to make up its mind on whether 'CPU Size' means die size or package size, and while the underlying information is (mostly) factual, it does a meager job of separating the two concepts.
he answered the question without having to go into that great of detail. i wouldnt mind learning what you are suggesting but i feel the video was good enough since it proposed a question and gave a solid answer in a short enough video as to not lose your attention.
My takeaway from this is that it could definitely be a huge performance boost, but it's too difficult and expensive to really pursue.
I don't know, those wafer scale chips that Cerebras made for AI deep learning were pretty awesome. I would love an APU of that size for my PC.
Good thing for getting people from both sides. No bias detected.
Seconded. I like how they purposely talked to both companies this time.
Why can't I use more cpus then one for single pc like 4 or 8 or 10?
I know about pronlems on managing tasks and distributing work
After we come up with solutions for that
Is there any other big concern ?
Having consistent clockspeed across a die could potentially be solved by dividing 'core clusters' into domains with an asynchronous bridge between the domains. Could also allow them to run at different clock speeds. But note that a significant amount of energy is used for transporting a bit 1cm compared to processing said bit.
One major issue about higher power consuming chips (when adding more cores at the same speed) is transferring power from the source e.g. VRM through the PCB via the pins/balls to the die. This has some impedance (Z), where mainly the inductance (and to some extend resistance) are the main issues. The voltage (V) the transistor the transistor will get will effectively be Z*I (impedance times current) lower than the VRM output. When you draw more current, the voltage seen on die will be smaller, i.e. Harder to maintain stability.
To reduce impedance (through the pins) several pins are assigned to the same voltage rail e.g. Vcore as this impedance then is reduced by being put in parallel. I belive Intel did this when going from (was it?) 9 to 10gen where the number of pins and socket were the same but there were no electrical compatibility between the two Gen.
The video left out one important detail: there is also a hard limit on how big the chips can be made, which is called the 'reticle limit'. I believe the reticle limit for 7nm TSMC is somewhere around 850mm2. By comparison the largest consumer GPU chip (GA102, used in RTX 3090 / 3080) is 628mm2.
I had this exact question just now! thank you for answering it.

I’ve just always wondered why they don’t include bigger caches. There’s so many “updates” the seem to just add a little more cache which makes one wonder why they didn’t in the first place. It’s not a big change that would dramatically reduce yield or increase price.

Thank you. I have always wondered about this.
Or think about it this way:

At 5Ghz clockrate, or 5 ticks per nanosecond, an electric signal travels only 2cm before the next one is sent.
Try keeping that all synced up...

Adding more than one CPU would be nice. Sli cpu or combing slightly different cpus on the same motherboard.

Ah to see the S85 from BMW warms my heart. Such a great car engine
I recall looking at CPU stacks from IBM in some of their literature - cubes about 4 inches square. Was a long time ago, though, and intended for use in some of their mainframes.
You were looking at the aluminum cooling surfaces of there ceramic modules. In the mainframe world there is no such thing as a CPU chips rather the CPU is made of modules. The brilliant thing about how IBM build mainframes is there ability to design CPU modules based upon heat output per module. This way the modules can be cooled by an ordinary fan. This is called "impingent cooling". When u open up a mainframe you will see a bunch of fans in a hosing blowing onto these very tall aluminum cooling towers. This changes rhe way the entire machine is cooled. Years ago the machine were in a data center that were ice cold, due ti the fact the a/c was blown down into the floor and up through each device. Then IBM changed to include liquid cooling. That was a radiator under each machine that had cold water circulating in it and a fan blowing over it. Now they use this new cooling system and the rule is "if the temp is comfortable for you, its comfortable for the machine"
IBM design is light years ahead of the PC world. Always has bee

Your fail is huge. He says a v10....and a v10 engine is displayed. The next scene shows a guy in a car...when Linus mentions the smaller car.......DOH
My first thought about this was well it overheat
The single most limiting factor is the transit time, which make clock frequency lower for a bigger die.
Some of you can recall the Pentium II cartridge processor, with the core running at 400 MHz. It had the cache memory installed on the same cartridge, but not onboard the chip, running at 200 MHz.
Smaller the transistors size, smaller che chip, higher the clock frequency.
Now Apple started a trend, with a relatively low computing power CPU, the M1, but with the instruction set highly optimised toward the applications, and the results are excellent. But only with their applications built with their compiler with their programming structure. The x86 can run any software written in any language with a variety of compilers.
