There are 1.5 billion x86_64 computers in use right now, and the PC market growth is being driven by more powerful laptops. The "Post-PC" meme was investor PR because it was not expected that the PC market was going to experience anymore significant growth after the start of the 2010s. It never had anything to do with PCs "dying" a Smartphone is never going to replace a PC. There are more Smartphones on the planet because Smartphones are cheaper and more expendable, and a single person may upgrade to a new Smartphone every year while keeping the same PCs for roughly 5 years at a time (A full hardware cycle for PCs in the industry is generally considered closer to 10 years in many cases)

There's literally no advantage in using x86 other than you have more performance over ARM at the cost of crunching more TDP.

Stop thinking x86_64 userbase care about architectures. Majority of people want cheap stuff that just works anywhere and don't have the time to build their own PC gaming console. Even a 4K smartphone can be way cheaper than a 4K compatible PC. That gaymer monitor would even cost as much as that 4K phone that can work interoperably with smart tv's and other phones.

The patch for Meltdown will fuck over enterprise users, but the generally population won't see a difference in performance. Pretty much every modern CPU architecture is vulnerable to specter.

Still werks just as efficient in mobility and being a RISC isn't all disadvantage, it's a completely different architecture. ARM and other arch just doesn't care about the desktop market yet because the phone and server market is very solid.
>Users do care about legacy compatibility, part interchangeability, and software upgradability. Which Smartphones lack
Smartphones come with warranty which is what pure FOSS will always lack unless it is red hat shipping some sort of expensive enterprise android but red hat is suspicious as their logo
After the warranty is expired, it's probably beyond repair and no one have enough pajeet support in android as windows. Smartphones evolving a lot is a good sign that the market enables performance competitions among disparate tech companies or OEMs.

No they will absolutely not because they have no reasons too. Its too big a risk to take when, like you said, normalfags don't care about the architecture, and companies like HP are more than comfortable pushing out low-powered Intel Atom and Pentium machines for low price points because Normies actually expect their software to run.

Grand Theft Auto V is the best selling video game of all time, it's 70GBs in size, and the majority of its sales have been on some x86 machine, wither thats consoles or on PC. the original versions accounted for only 30 million of the total 80+ million sold.

>I bet you're masochist enough to like those little incermental performance intel does which only holds us all back from breakthroughs.
I like them, not because I am a masochist but because I am a GPU programmer. I still enjoy Moore's Law performance gains.
Also its not entirely the fault of Intel but rather the fact that whenever they release a new architecture they have to make sure it supports legacy code.Nvidia (and AMD) doesn't have this issue to the same extent because of the way GPU drivers work.

I'd like to see different architectures flourish but I don't think it's possible mainstream until we have a transparent compatibility layer in an operating system, which might be difficult. I'm talking like, so you install some *nix on your RISC-V machine and invoke an x86 Windows binary and have it just work. While it would be nice and technically possible with things like qemu and wine, I don't think we're there yet and you simply cannot migrate from 1 hardware system to another without either !) porting everything or 2) maintaining comparability in some form that is transparent enough. In addition to this it ALL has to be ubiquitous which is just a pipedream at this point, like you'd also have to go the other way and say have a method of running RISC-V POSIX binaries binaries on x86 Windows and whatever else.
>PPC on ARM
>et al.
No matter what there cannot be change without significant improvement or a compatibility bridge. The best examples I always point to are video displays and their input options, remember the times when things like HDMI and displayport were new but everything still had component input, it's necessary otherwise people wouldn't migrate. The same is true for hardware platforms and the pairing of software, unfortunately there's just a lot of factors in software that are hard to account for in terms of compat.

No. It's because your CPU doesn't support the rdtscp instruction, which that example uses for timing. As a quick hack you can alter the code to call rdtsc(); instead of rdtscp(&junk); in the two places that do it, and sometimes it'll work, but erratically. Try playing with the CACHE_HIT_THRESHOLD too to see how it affects it. Sadly this does not mean your system is necessarily more safe, it just probably needs to be targeted in a different manner.

I call bullshit.
From elsewhere:
>The meltdown exploit demonstrated that having the kernel mapping available in userspace can be risky. Modern processors prefetch data from all mappings to run as fast as possible. What data gets prefetched depends on the CPU implementation. When a running userspace program accesses a kernel mapping, it will take a fault and typically crash the program. The CPU however, may prefetch kernel data without causing any change to the running program. Prefetching is not usually a security risk because there are still permission checks on the addresses so userpace programs cannot access kernel data. What the meltdown researchers discovered was it was possible to measure how long data accesses took on prefetched data to gain information about the system. This is what’s referred to as a side-channel attack. The KPTI patches reworked how page tables are set up so that the kernel is no longer mapped in userspace. This means that userspace cannot prefetch any kernel data and thus the exploit is mitigated.
>Actually writing an attack to collect useful data from this exploit can take weeks or months to develop for a single system. Still, in the interests of security the KPTI patches were merged to close this hole. The side effect of not having the kernel page tables always mapped means that the TLBs must be flushed more often, causing a performance penalty. By default, Fedora has KPTI enabled to provide security for users. KPTI can be turned off by passing “nopti” on the command line if users don’t want the performance hit.
Note:
>Actually writing an attack to collect useful data from this exploit can take weeks or months to develop for a single system.
