One Core, Single thread, Cache, recommend.

Good afternoon gents,

I need a single core CPU with the best single thread performance and a large Cache memory. Please recommend the best CPU on the market or if I need to put together some parts to make it happen and what's the best way to go about it.

I am new to computer. I have won academic awards in other fields.

Upgraded from am4-am5 cpu now runs very hot

Specs

5080
Ryzen 7 9850x3d
G Skill 32gb 6000mhz ram
Corsair 850w psu
Asus B850-E WiFi mobo
Arctic case fans
Arctic liquid freezer III pro 360 cpu cooler

CPU now runs very hot over 90C when under load like playing a game or running benchmark off of hwinfo app. Idle temps sit around 35-40c

Just wondering if anything looks out of the ordinary with my build. I am aware top mounted is the best but due to radiator size and heatsink of motherboard I could not fit it.

Any recommendations of what I should do or look at? I am going to try to reseat cooler now. Also this is not the same cooler I used on previous cpu.

9800x3d or 9850x3d?

I’m building my first ever SFF PC this weekend, and the last decision I need to make is the CPU.

I know the 9850 performs better, while the 9800 is more efficient and runs cooler.

How have people found the 9850 in SFF builds? Does it require extra careful thermal management above and beyond the 9800?

Case: nCase M3 Grater
PSU: Corsair SF1000
CPU: 9800x3d or 9850x3d
GPU: ASUS ROG Astral RTX 5080 OC
MB: ASUS ROG Strix B850-I
Ram: Kingston Fury 64GB (2x32) CL30
SSD: Samsung 9100 Pro 4TB
Cooler: Noctua NH-D15 G2
Fans: 3x Noctua 140, 1x Noctua 120 (Rear intake, top and front exhaust)

PC manufacturers are forced to use more expensive 18A chips since Intel is out of older processors

After reviewing information about Intel’s current chip shortage situation, it sounds like PC manufacturers are being pushed toward more expensive 18A processors, whether they want to or not. From what I understand, Intel sold most of its older chip inventory to the server and industrial markets because those segments generate higher profits, which now leaves fewer affordable processors for consumer laptops and PCs. What surprises me the most is that laptop brands now have to redesign and adapt products for these newer chips, and that process alone can take months and increase the shortage even more. Intel’s newer technology definitely promises better performance, but I’m wondering how many regular consumers are actually willing to pay noticeably higher prices for it. Do you think this could really cause a huge drop in PC demand?

Steam Machine's curious newcomer's FAQ -//- What is it? What can it do? What *can't* it do?

Availability //

- how much?

haha, that's the [insert Steam Machine price here] [insert currency here] question my friend!

- when?

Lemme look into my crystal ball 👉🔮

Performance //

- what should I expect?

Short version -- "horsepower"-wise, expect a PS5.

Long version -- Steam Machine - a comprehensive hardware breakdown (section 2 & 3)

Hardware //

- what exactly is under the hood?

Short version -- AMD-issued laptop-grade parts & other laptop standardized components, you can only change the RAM (laptop 'SODIMM' DDR5) & storage (NVMe M.2)

Long version -- Steam Machine - a comprehensive hardware breakdown (section 1)

Note : the Steam Machine has NOT been designed to be a powerhouse, it's goal is to allow players the most straightforward access to gaming technologically achievable AND (although Valve didn't say it outloud) designate a hardware target for game studios to hit as the least powerful PC they should optimize for-- the very same way the SteamDeck became an incentive for many to optimize a game to run on it because of the huge market On-The-Go gaming became because of it.

- can I use mouse/keyboard?

It's a PC so yes, it can handle multiple control methods seamlessly, you can switch from M/KB to controller whenever and edit control schemes however you want via Steam Input

Software //

- what can I expect to run?

Short version -- Everything a SteamDeck can launch, it's running SteamOS too

Long version -- it's a PC (the Deck too but that's a whole other rambling) so everything a PC can BUT, _out of the box_, it's not your regular computer running Windows (even though you could install it instead if you wanted), _SteamOS is based on Linux_, so here's in details what you should expect :

  • not 100% of all games ever are guaranteed to run on Linux: a huge share of them straight up do not have a Linux version, but we can still play on Linux thanks to a little thing called WINE, that Valve picked up, made their version (doing that is commonly called a "fork") optimized for gaming they called Proton, which takes the Windows version of games, operate some software-level black magic that you don't really need to care about and through this, lets you run games on Linux! BUT, as software is never perfect, there is obviously some incompatibilities that either won't let you launch a game at all or some quirks causing issues at various levels of your gaming experience // Check out ProtonDB to check the playability of games on Linux via a rating system & user reviews that often includes community fixes where necessary + Games will have a SteamDeck/SteamOS compatibility rating on their store pages for your convenience! This rating is dependent on Valve testing so it may take longer to show there than on ProtonDB but it's also a form of official validation
  • no games with kernel-level anti-cheat, unless explicitly stated by the game studio-- that includes CoD games (since at least 2019), Battlefield games (since at least BF2042), Escape From Tarkov (sortof), Destiny 2, Marathon... // Check out AreWeAntiCheatYet for the full up-to-date list of games with Linux-enabled anti-cheats (and obviously those that don't too)
  • software available under the form of a "Flatpak"-- Linux allows you to install whatever you want but since it's also just as easy to just f**k it up and botch the system, Valve set it up to be immutable: you can't modify it without switching off the safety on it (you can do whatever you want but if you want it to stay stable and retain official support, leave that as is) However, you can install software on it the same way you install apps from the app store on your phone: it goes for browsers, office software, creative software, etc... if there's a Flatpak version of it, you can install it via "Discover" (the "app store" that ships with it) // Check out AlternativeTo (I've already applied the "Flatpak" filter on that link) to parse through software you're likely to find in Discover to install.
  • Not all softwares you know and are familiar with on Windows have a Flatpak version, let alone a Linux build-- if you really need something from Windows, not all hope is lost: through the same methods Valve made the Deck & now the Machine/Frame run Windows-only games, there exist ways to run Windows software but this is not a guarantee either, Linux compatibility went a loooooong way over the years, non-game software is quite volatile so while new support is introduced regularly, subvert your expectations, look up if something can be run and how well it will run // Check out Bottles or this video guide from their docs to learn the basics
  • There's use cases where megacorps either don't see the point of supporting Linux or straight up don't play nice intentionally (whether or not reasons behind are legitimate may vary) such as streaming services for DRM (aka content protection) reasons, mostly niche stuff (such as Blu-Ray playing & Dolby 7.1-- from what I heard) but can be inconvenient at time when you encounter those...

- can I mod my games?

It's... hit or miss. Most of the answer around this will be available here

- can it run VR?

While the Steam Frame has been designed to run as a standalone device, Valve has of course also worked on PCVR tandem between the two, it will absolutely work for VR regardless of the VR brand, as long as the headset supports Steam Link/SteamVR or the manufacturer's streamer app has a SteamOS/Linux compatible version.

Alternative //

- can I make my own Steam Machine?

Short version -- Of course, you absolutely can, I made my own, a bunch of others did too!
HOWEVER: SteamOS offers no Nvidia GPU support, unless you have literally anything else, it won't work. // Doesn't stop you from the next best options -both of which have Nvidia support- like Bazzite (Deck/Machine-like experience) or CachyOS (PC-like experience) (there's other flavors of Linux but the most popular & reliable for gaming are those two)

Long version -- The GeekCube // a DIY "we have GabeCube at home" project (section 1)

Other //

- my question/worries/expectations are not answered by the above!

reply down here, I'll try to convince the mods to pin this at the top of the sub as I update this post with more answers further down the line!

NVIDIA Rubin Could Turn LPDDR Memory Into AI’s Next Battleground

What caught my eye here is how fast AI hardware is moving into territory that used to belong mostly to phones. LPDDR memory was once something we mostly discussed in the context of iPhones, Galaxy devices and battery life. Now NVIDIA Rubin alone may demand more of it than Apple and Samsung combined.

Personally, I think this is where AI stops being just a data center story. If memory gets tighter and prices rise, users may feel it through more expensive phones, weaker base models or slower upgrades. Are we ready for AI servers to quietly decide what kind of smartphone we can afford?

Mon CPU tourne apparement avec une fréquence trop basse

Bonjour,
Quelqu’un pourrait t’il me guider pour savoir quoi faire, je ne comprends pas le diagnostic de Pre Bench. Je pense que mon cou a un problème mais il est neuf, que dois je faire?
