I have seen dozens of announced vulnerabilities for both AMD and Intel CPUs ... what I have never seen is a doumented instance of any of these vulnerabilities ever being exploited. So all that's really of note here is fanboi bickering which has as much valididity as "ntel is still on top for gaming performance, and AMD already humiliated them in everything else ". The definition used for "everything else" is specious.
A PC is a tool ... a tool can only be judged at how well it does it's job, so let's define it's job.
a) Did you build a PC to run benchmarks and get your name on leader boards ?
b) Did you build a PC based upon performance in things that you might do one o do few times a year ?
c) Did you build a PC to play games and run applications on a frequent bias.
d) Did you build your PC to run apps you will never use
Practical people build the boxes based upon c) and c) only ... fanbois squawk about a) and b). Let's look aty TPUs test results. Three is no "Best CPU" .. only the best CPU for a specific set of applications. Looking at 3900X vs 9900KF
1. Cinebench - a) category ... we have yet to be asked to do a build which maximizes Cinebench performance or had a client who uses it to make a living, it's the medical equivalent of a scalpel in a Chiropractice office. We do have lots of folks who use CAD, adding all the PCs in all the offices we've been in, there's prhaps 1 rendering box for every 200 CAD boxes and AutoCAD at $5,000 per seat ($2,00 per year) is not exactly on a any significant % of PCs.
Gotta give an easy win to AMD here, but a 0.50 on market significance.
2. Game / Software Development - d) category ... again an easy win here for AMD; Again, not a lot of market significance, as above, teeny user base.
3. Web Related - c) Category ... performance is split between red and green camps but with differences of /10th of a second, who cares ? Uses can not react quick enough to take advantage of it.
4. Machine Learning \/ Physics / Brain Simulation - d) category. The size of the market here is completely insignificant, and if the % of users here who run this stuff ia mor than 0.2% Id be shocked... Another win for AMD, but not one that will matter to 99+% of the forum audience.
5. Office Suites - Finally a category c) item ... stuff most folks will use frequently enough to matter in a CPU choice. We get a 4% win for Intel in Word, a 1% win for Intel in Powerpoint and a 1% win for AMD in Excel ... the win goes to Intel but the margin is so small as to render in insignificant as "user lag" will make it unnoticable.
6, Image and Video Editing - Another category c) items and here finally one that matters. A 10% advantage to Intel here in Image Editing and a 4.5% advantage in Video Editing. While not a bit thing market share wise, it's over 100 times more significant tham machine learning, brain simulation, software development, etc. 1st significant win for either side here. Google OCR is in the test and it's significant one ... we might use it 3-4 times a year so we use Adobe OCR to do thatas do most of our clients.
7. Virtualization - As we're speaking to desktops not Server functions I'd skip this. Suffice to say Intel gets the win on VM Ware ... AMD gets significant wins in MySQL and jav ... a Bog reason to go AMD ,..if you use them. No relevance if you don't.
8, File Compression / Encryption - A category b) items for most. less and less as time goes by. Big Win for AMD on the compression / Bit win for Intel on encryption ... Who cares ? Not many
9, Media and Sound recording - Would be at thing for youtubers, musicans and similar sorts and similar sorts, AMD dominates the media / Intel dominates the sound... if those are your thang, pay attention ...if not like most, ignore.
10. No one argues the gaming so not worth mentioning.
In short, there is no best CPU... there's only best for you do on your PC. If office suites, gaming, Adobe products or AutoCAD are your thing, Intel is the onbviois choice. If doing brain simulation, encoding, rendering, virtualization is your thing, AMD is the obvious choice.... just look at what YOU do and decide accordingly. As to the invulberabilitoes... call me when ya ready to publish "Patient O's" story. As of yet , I have not seen any instance of theese invulnerabilities being exploited. Until that happens, I'm not paying attention.
