CPU’s Look similar no matter how many cores they have, Why?


Have you ever wondered why all CPU’s almost measured the same size, we know they have different sockets but all almost look the same size except some heavy ones, as AMD’s THREADRIPPERS and Intel’s Xeons.

Simulating a comparison-

We all have seen these processors before, for demonstrations let’s focus on these identical processors in terms of processors size-

Intel Pentium = 37.5mm x 37.5mm

Pentium gold performs well for normal office-based systems, it has a die size of 14nm with 2 cores along with a clock base frequency staging at 3.70ghz, It has 4 threads, and max RAM support for 64gigs.

AMD Ryzen 9 3900x = 39.8mm x 39.8mm (maybe I could find more close reading to the above mentioned if I would have searched more, but nevertheless, you got my point, right?)

Ryzen 9 3900x is a beast 12 core gaming + workstation CPU for creators and developers, with a base clock of 3.8ghz and max clock of 4.6ghz, got 24 threads for multi-threaded tasks. this one’s based on 7nm architecture, This one supports a max of 128gigs RAM.

Intel i7 9700k = 37.5mm x 37.5mm

Coming to next participant of our research, i.e. i7 9700K is an 8 core 8 thread CPU made purely for great gaming and creative performance, this has a hand over some other processor due to it’s higher clock speeds and a combination of 8 cores, makes it one of the budget gaming CPU’s out there. this supports a maximum of 128gig of RAM.

How that fits onto some Centimeters?

Now getting to see these mentions above we can see that all these processors can get different performance levels but they, almost have the same size just what we were talking about.

Comparing the specs of those processors to a very deep level tells us clearly that there’s more to the total size of CPU other that Cores, Threads, and Cache units, it also matters a lot upon lithography style (22nm, etc.), manufacturing techniques (CMOS, etc.), architecture (64bit, etc.), BUS architectures and much more.

Architecture/Manufacturing layout is the game-changer-

Some old processors such as AMD FX 8300 have 8 cores and a great clock speed along with a good duty cycle, but it was built on a 32nm arch. Therefore, more heat generation/energy usage per clock cycle and less work done as compared to 7nm or 14nm ones, which nowadays run on very much higher clock speeds and have less TDP.

New Architecture technologies also include many new ways to integrate many billions of transistors in a very small space efficiently. Less area means the transistors will be close enough to each other to make signals fast and energy-efficient without generating too much heat and therefore performing more calculations per clock cycle.

Distance Matters-

You may think of package size rather than the size of the actual CPU. Most of the size of a processor’s package size is contributed by connections- pins or ball grids. The actual part that does the work is that little lump on top.
Most performance improvements are gained by less room between components, which contributes to a smaller size. Think of it this way- if you needed to tell your friend something, would it be easier if he was right next to you, or if you had to walk to another room?

Computer processor execution is to a limited extent identified with the engineering. You’ve accurately learned that you could fabricate a CPU with a lot bigger pass on that is fit for better. Besides the financial issues which I suggest above, there are additionally certifiable issues.

All of these semiconductors require capacity to manage their responsibility. Construct a CPU with more semiconductors, and it won’t be cold – it’ll be more sweltering!

Some force could be saved if clock speeds were lower – there is an outstanding connection between the clock speed of a chip and the voltage needed to work the CPU. This implies that lower execution parts can be unmistakably more force productive than better parts. As you push towards better cutoff points, you run in to control issues. You may likewise run into issues where you essentially can’t switch the semiconductors rapidly enough and run into a clock speed divider.


CPU has major considerations like core-count, clock speed, calculations per cycle, threads, TDP, and Max temps. etc. but there even more to that even 2 same-sounding CPU’s in every aspect can have a huge difference in performance even due to a slight difference.
