currently, X86 has over 1000 instructions, many of the instructions are not in use today and are only kept for backward compatibility with old software. I want to know whether it would be feasible to cut many of the obsolete instructions from a CPU's main cores and have any programs that use the cut instructions moved to a couple of "compatibility" cores that keep the full X86 instruction set. this should be much faster than instruction set emulation, while still cutting down on die space and bringing some of ARM's advantages to X86 -
Microsoft continues its battel to get rig of old unfashioned hardware for its latest Windows 11 release, this time with deeper changes. Quotes Well, you either have a PC with "new" CPU after 2008 so it doesn't matter or you don't care for Windows 11 anyway -- in both cases nothing changes for the adoption rates of this Windows generation.

I have an Acer Aspire One 722-C6Ckk notebook running an AMD C60 cpu with 2GB DDR3 Memory. I want to turn it into a home NAS server. But, since this is an x86 architecture cpu, I don't know which NAS OS can run on it. I've only ever use Windows, so i have no idea how to use FreeBSD or Linux based OS. Though I've checked the requirements for TrueNAS CORE and SCALE, they all need a 64 bit cpu and at least 8GB RAM. I don't have any particular OS in mind that I want to run. Anything that can run on my notebook as a server OS is ok with me. I'm not ever sure that if it is even possible to turn my notebook into a NAS! The hardware is more than 10 years old now. Now, if it is possible, which OS can I use to turn this old notebook into a NAS? Also, if I'm able to turn my notebook into a NAS, will Jellybean run on a 32 bit cpu? Or will I have to run PLEX? Thanks.

Intel however is not giving up on the partnership with Oracle and insists that the new line of Xeon Scalable offerings will be a strong player on the enterprise market. Quotes One thing is clear -- Intel can no longer expect its hyperscale client base to adjust their upgrade/migration cycles to the pace of its own R&D and manufacturing capacity delays. Times have changed. Source: https://www.crn.com/news/components-peripherals/oracle-bets-on-amd-ampere-cpus-ellison-says-intel-x86-architecture-is-reaching-its-limit-

Summary Under the slogan of "Envisioning a Simplified Intel Architecture", Intel has published a draft specification for "X86-S". This variant of the venerable x86 CPU ISA would strip out all of the legacy 16 and 32 bit components as well as several obsolete features, leaving only x86_64. Quotes My thoughts I think clearing cruft is an admirable goal. It's kinda crazy that a Ryzen 7000 or Raptor Lake processor still has to act like 8086 when it turns on. Less architecture also means less places for bugs and vulnerabilities to live.

Budget (including currency): sub 250 EUR for mainboard, cpu and ram Country: Germany Games, programs or workloads that it will be used for: Steam cache, 2 Discord bots and a few small scripts Other details Main focus should be energy consumption and speed. Physical size or looks doesnt matter too much Hello guys, i want to build a small ish storage and home automation server, it will have a 2tb ssd for storage and a 2,5gbit network connection to my main pc as well as a 1gbit connection to the rest of my Home Network. Its main purpose will be as a steam cache, as my Internet connection has only 100mbit/s download and no way to upgrade it for less than 6k EUR for a fiber connection. Other uses will mostly be some home automation stuff and 2 discord bots, as that currently runs on a xeon e5 2680, which draws a lot of power and heats my room up quite a bit. As an OS id prefer some linux variant as i already have some experience with it. My question is, if that will work at full speed (500MB/s) as well on ARM hardware or if there would be drawbacks like speed constraints. -
Summary The latest macOS beta appears to be removing x86 emulation on install. The wording’s meaning and reasoning behind it is anybody’s guess. Quotes My thoughts If Apple actually does remove x86 emulation, it may force lazy developers to move forward with native code. But would also be a major kick in the teeth to Apple Silicon adopters who believed there would be compatability.

Please tell me no, I'm tired of apple taking over in everything. I dislike apple, mainly because how the people that use their products behave. Many girls I know did this stupid challenge video where they put down a finger if they wanna date the guy described.. kind of. There's just a voice saying "He is cute but he has bad teeth" "He is cute but he is short" AND "He is cute but he has an android" I watched like 50 videos before one got their finger down about the android guy. That's the kind of person I talk about, and I kind of developed hate for apple. I know I shouldn't but idk I can't really control it I just kind of hate them. But any way, Please tell me amd and intel has what to show apple, I don't want macbooks to take over everywhere. In my country they are still rare, but with how many people use iphones in my country it's just because It didn't really become a trend yet.. No way they can just beat 2 companies with all the experience and years behind, right? right..?

So I am waiting for the surface laptop go but it is in s mode of windows and says it cant run x64 apps that are installed not from microsoft store even after switching out of s mode so. Can anyone say that they do work and what about x86 apps?

I've never taken any EE classes nor any computer architecture classes, so I'm coming from a newby, beginner perspective. All I'm getting from the internet is mainly "ARM is less power hungry and used for mobile devices while x86 is intel/AMD." I'm not even sure if this can even be ELI5'd but, what are some the technical differences that differentiates ARM from x86 that makes it suit different devices?

Model Matrix and Vector Transforms Optimized By SIMD
patrickjp93 posted a blog entry in Real Game Engine Code Optimization
I'm sick to death of people telling me "if it was so easy, the game devs would have done it by now. They know better than you do." Here is visible, incontrovertible proof that the games industry can get a huge boost from taking advantage of SIMD today, especially when games require Sandy Bridge or later hardware (meaning AVX is available, but not AVX2 for our purposes). First Example: Mesh Transform By Translation Using AVX Intrinsics Example updated and trimmed for readability. My average timings and variance for a 4960HQ on my Macbook Pro Retina under Fedora 24, latest kernel as of 10/15/2016: Compiler: Clang++ 3.8.0 Flags: -std=c++14 -O3 -march=native Mesh size in floats: 90000 Scalar translation took 6.08489e-04s +- 0.11032e-04s Vector translation took 5.82480e-05s +- 0.14391e-05s The short of it is you can write tighter, denser loops with a little bit of effort. While the latency for each vector add is 3 cycles and each multiplication is 5, multiple iterations can be in flight at once on a single thread. The throughput for the vectorized version is 8x the scalar version without any unrolling. Thus, the loop can also easily fit into the small loop detector which can shave off some cycles due to prefetch removal and result forwarding between iterations. Assuming you don't run out of memory bandwidth, you can actually do other tasks on this same core without using hyper threading as long as they do not depend on the result of the mesh manipulation. Looking at the SB block diagram, with each clock achieving both an 8-wide vector multiplication and 8-wide vector addition, you can achieve more than 50GFlops per core on a 2600K, but the memory bandwidth will not allow you to load and store the results as quickly as you can request and produce them at a rate of 50GB/s without high-end dual-channel DDR3 or a quad-channel configuration. It would be best to use a C++ 17 stack-less resumable function to encapsulate this and do short bursts of another task when more than 3 L3 cache misses happen in a row (this can be tracked with a hardware profiler to determine optimal burst lengths). If there is interest, I can go into nuances of leveraging vectorization techniques in conjunction with other data transforms relevant to gaming (though I'm not giving away my AVX ray tracer). I can also look into benchmarking multicore use of this and balancing it out against other tasks to achieve best performance for a given configuration. -
TLDR; Why buy a x86 system when Apple Silicon is sufficient for most tasks (browsing, word processing and video editing), unless one's primary use of a PC is for gaming? Is this a valid argument? I've been mostly a PC user (owned a couple of Macbooks back in the Intel days). I'm currently on a Ryzen 9 5950X system with 32GB of RAM and a RTX 3090. I've been thinking about upgrading to 7950X3D until I saw M2 Mac Mini. My primary usage on PC are: Occasional gaming (Arma 3, Cyberpunk 2077 and Doom Eternal) Light coding (web dev) Video editing and transcoding (Davinci Resolve, handbrake and Topaz Video Enhance AI) Photo editing Trading (using web browser) The arguments for me to stick with PC are as followed: Upgradability Gaming The counter-arguments to the above are a followed: I upgrade every 2-3 years and each upgrade costs around USD $2,000. Since I rarely play games now and if Apple keeps on churning out Macs like M2 Mac Mini, I could upgrade every year right? For the work I do, MacOS and Apple Silicon seem to up to the task if not better than their PC/Windows counterpart in terms of performance. I am genuinely interested in getting others' thought on this. I did not intend to start a flame war b/w PC and Mac users. Please keep this a civilized discussion. Thank you

I just installed Ubuntu for the first time on an old desktop and it was working fine on Ethernet but when i booted it up today it couldn't fine any Ethernet cards. I know the wire and everything works because it works fine on my windows PC. Any help would be great thanks -
Just receive this motherboard. Its m-atx size, no bridge chip, SoC design like AMD Ryzen. Motherboard layout is a little bit unusual. No drivers for now, so CPU-Z quick test. Performace is not good, but for light weight application is enough.

Out of curiosity, why doesn't Qualcomm enter the X86 market? I know about the licensing deals between Intel and AMD, but considering that AMD needs some cash (or did, before Ryzen, since I'm sure they're profitable now), and that AMD are the ones holding the X86 patent (iirc), why hasn't Qualcomm tried to enter the X86 market with a license deal with AMD? With Qualcomm's vast cash pool, tons of resources, and a virtual monopoly on the mobile market, I'm sure that they could've hired a few people who're experienced with X86 and developed a viable architecture. So, why haven't they?

I have recently done a clean install of windows 7 32bit x86 and the first thing i did was to check for updates. When i clicked in the "check for updates" button, it kept on saying "checking for updates". I left windows update to run for over 1 hour and nothing happened. I have also attempted to reset windows update settings following the instructions from this link (https://support.microsoft.com/en-gb/kb/971058) twice. Does anyone have any idea of what could be wrong??? Thanks

so heres the problem, I've been hard at work for months on end trying to get a windows x86 spec'd tablet ( Acer s1003) to run Android. I have an iso for Android x86 for the tablet and is the only install I have had any success with. the sucess is that it installs and can not boot. the installer iso I have has a partitioning "feature?" and I am unable to figure out how to make Android boot. the tablet is uefi based and 100% can not boot without a file named "bootia32.efi". oddly ubuntu distros are unable to be booted from within the bios. windows installations with the bootia32.uefi file loads and then crashes on all versions. android has been my only success oddly... any ideas on what I may have left out?

Have a old laptop, it killed itself for the 3rd time with Android x86... Anything better and more stable exist? OwO -
It would seem that x86 chipsets are stagnating getting to the limits of what they can achieve through die shrinks and with the evermore popular parallel computing tasks it's looking like ARM RISC based chips could be the future with it's low power low transistor design. x86 instruction sets have become bloated and often complex instructions take more than 1 cycle to complete whilst ARM instructions often run in a single cycle. ARM chips are catching up with their x86 counterparts and with large companies like Microsoft and apple making a push for ARM does this spell doom for Intel and AMD x86 chips or will they prevail . It will take a complete over hall of current software to make such a change possible but it's looking likely that this task will be undertaken. Here is an interesting Video that gives some food for thought about this, what are your thoughts is it the end of an era of power hungry x86 CISC based computing or do we need to put away the tinfoil hats for when the aliens come?.

Hello, I seem to have encountered a problem, My RCA CAMBIO 10.1" windows 10 home edition 2-in-1 tablet has just pulled a black screen on me, here are the steps to recreate it, 1. Make sure you're signed into an account with admin privileges. 2. Press win+a to attempt to bring up the action center. 3. Swipe left with finger 3 times. 4. Shut down the tablet with power button. 5 Turn on tablet. 6. Sign-in to the same account. Now you have the black screen! This is the best info I can get you Ctrl+alt+del still works, that I the only way I can get the task manager up, or log out of my account. What do I do now? Thanks in advance!

Why is Apple not using its incredibly powerful processor (a12x) in macs while windows is working on mobile smartphones like snapdragon 850??
