Title is "Technical Details of Why Cloudflare Chose AMD EPYC for Gen X Servers"
Submitted title was "Why Cloudflare abandoned Intel for AMD for its latest servers".
Yes, there are lots of stories of individuals and companies choosing AMD over Intel. For me, what's more interesting would be any contrarian view listing the compelling reasons to pay the higher price for Intel instead of AMD. Off the top my head, some reasons would be: - Intel AVX-512 instruction set - Intel 4 and 8 sockets What realistic workloads have a better performance/cost advantage on Intel vs AMD EPYC? If yo…
https://cpu.userbenchmark.com/Compare/Intel-Core-i7-9700K-vs... Comparing the similar priced Intel and AMD CPU's shows Intel has a slight advantage. Reading the conclusion, it seems for Overclocked performance, AMD is the winner, especially when factoring in large core workloads. As games and typical "home-user" scenarios are not designed to take advantage of large multi-core CPU's, Intel would appear to be the bette…

If you have crappy tooling, the software other people write -- in house or commercial software-- runs crappier on your hardware.
But it's irrelevant if it works faster than intel

I'm interested to know where people use AVX-512. Off the top of my head, I can think of machine learning and crypto. Machine learning---that is, matrix/tensor stuff---seems more like a GPU workload. That leaves crypto, but most crypto (eg ChaCha or Keccak) only make use of 128 or 256-bit extensions (in fact, they seem to designed with this constraint in mind.)
Real-time audio processing is probably the most common case where you see huge gains in SIMD on the CPU but very minimal gains on the GPU. Other examples are certain polynomial approximations and physics simulations.
Also string manipulation, parsing, evaluating a regex. The overhead of getting to the GPU outweighs keeping it on the CPU core.

> SourceHut runs its performance critical infrastructure (git, builds) on AMD EPYC. These CPUs are sweeeet. The hard part is sourcing motherboards. I currently buy them from some dude in Germany on eBay because he's the only consistent source I've been able to find. Heh, you know that guy is with / getting a visit from the German BDN now.

I really wish AMD would focus on its tooling. The Intel VTune Amplifier is a fantastic multi-platform profiler that can help understand how effectively your software is using the hardware (Pipelining, micro-ops efficiency, cache usage, etc.). If AMD could come up with something similar, it'd make their offering a no-brainer. > https://software.intel.com/en-us/vtune
I think (without too much knowledge in this field) that AMD has had to play catch-up for so long in silicon that now the catch-up is complete, it will take some time to recognise organisationally that more focus on non-silicon is overdue. Silicon lives in an ecosphere, but without competitive products there's little use in investing in that ecosphere. If you suddenly get there, you need to change your game quite dras…

Cloudflare's CTO posts on HN, so many here seem to feel like they need to defend and herald the company for absolutely banal activities, as if they're personal friends. Whatever.
What? Cloudflare gets flamed for nearly everything on HN with bizarre conspiracy narratives. You’d think they were the NSA with the comments I’ve read.

Video encoding comes to mind.
I’m a big fan of CloudFlare. I own a little stock, and I moved our company over to it after running on a competitor for about a year. CloudFlare has been much better. Whenever I use the front end, it just feels like it’s made by people who actually need to use this stuff, and it is so straightforward. The api is great too. When we were with the competition it was ridiculous how often we had to have an engineer assist…
"it shows to me that they are willing to consider bold moves and that they aren’t afraid to be different" Because they benchmarked a drop-in-place commodity replacement as being a better performance-per-dollar for their operation? I'm not sure what's bold about that. I find the notion that they posted a blog entry about this pretty bizarre -- almost rinky-dink. It seems like it's pandering to the AMD fanbase (which I…
Yea you dont want to Criticize CloudFlare or a few other companies around here
CloudFlare can literally sensor the internet and consolidate all traffic to a single point of failure breaking the purpose fo networking and still be thought of as the greatest company ever, not evil at all

But wasn’t the same the case that last time they “disrupted” Intel with their amd64 and dual core CPUs? They caught up, but never really invested in the tooling. And then they lost market share again. Why would this time be different?
