The fastest CPU in the world

Thanks to Supermicro for sponsoring this video! You can check out their H14 AMD servers at:

Last year, AMD launched a 128-core CPU, and we thought, "It can't get better than this, can it?" Well, we were proven wrong, as now AMD has its all-new AMD EPYC 9965 equipped with a staggering 196 cores.

Purchases made through some store links may provide some compensation to Linus Media Group.

I like how Linus sells the server like it's something we all can just run out and grab.

[x_tune_x]

I consider the CPU test incomplete without the Cities Skyline 2 test.

[Pertev]

I like how this CPU does have more cores than all PCs, laptops, tablets, smartphones and raspberry Pi's combined I ever had in my entire life

[glennt]

I'm an IT Engineer that works in data centers. I'm starting to see more and more AMD hardware, it is all so crazy fast.

[JTCF]

11:35
It's thread limited to 256 because that's the max value of an 8-bit unsigned integer. *That's one hell of an oversight*

[Nitrospartan]

Time for the yearly "fastest cpu in the world" vid

[springrollpapi]

finally a cpu to run old school runescape

"Nobody would configure a system like this for a single user" -Linus, paraphrased. If I win the lottery I'll buy two. Yes, I enjoyed the video. I would have loved to see you run classic task manager to see the CPU cores. I have a 16 core 32 thread machine that seems to fill the screen with that but this would really be something else. Superb. Kudos to AMD and the Supermicro people.

It is limited to 128 threads because the Windows API to ask the number of cores is limited to 128.
Microsoft created a new function to determine the number of cores available, but a lot of code still uses the old function.

[RonnieDeuce]

Times have definitely changed. 10 years ago if someone told me AMD would someday make both the fastest desktop and server CPUs I would have thought you were absolutely insane.

This CPU is really like an anime villain that will go:
Impressive, You managed push me over 10% utilization

[benupde]

500 watt TDP! Thats like 1(!) 14900K 😳

[SirHuman]

I haven't watched the video in full but. For anyone curious, the CPU costs $14k USD.

[MaskRobloxOfficial]

I don't think anybody realise just HOW impressive running 192 instances of windows ACTUALLY IS... your CPU at home uses around 5-10% depending on your cpu meaning it could only run 10-20 instances of windows before COMPLETELY MAXING out the cpu.... this EPYC cpu only used HALF of it's cores... HALF.

Small correction from someone who does computer architecture research: The branch prediction explanation at 1:55 is inaccurate. In a modern OoO like this one, your branch predictor will easily speculate tens of branches ahead. 2-ahead branch prediction (which is what AMD has implemented) is a clever way to predict the outcomes of two blocks at a time to increase throughput of predictions, or to mask the latency of a slow predictor. Chipsandcheese has a good cursory article on this.

[Mullerchiropractic]

My server ignorance is painful, but somehow you made it fun, well done boys, well done!

[Riyozsu]

Cant wait for the epyc chip that will be able to download an entire AAA game just on its l3 cache in the future

[Nostalgia_Realm]

But can it run Crysis? 🤔 (Fully on CPU)

[CliffNark]

Damn, Jake has one hell of a car, a manual E92 is an awesome driver's car
