I'm looking at the MSI Raider gaming laptops. I see the GE73 has been supplanted with the GE75. The only real difference I can see is that the GE75 is using the new GEForce RTX chipset. Is it worth the extra $200?

More of a printer question for ya'll but figured this was still the place to ask:

In our office, we have a bunch of Brother printers. Sometimes when we replace the toner, the printer starts printing out pages with a ton of black smudges all over it. Pull out the drum and it's covered in toner. Worked fine before, only thing that changed was the toner. Try zipping that green slide back and forth but that doesn't do anything to the infuser as far as I can tell. Tried blowing it all out with compressed air. Improves it a bit but still crappy. Only thing that resolves the issue is a new drum but those get pricey.

Heads up another huge speculative execution vulnerability with all Intel processors. Intel recommends disabling of Hyper threading to prevent an attack. Microcode patch has been released but this will take time to integrate and the impact on performance will be in the ~3% hit on consumer applications and 9-10% range on datacenter, compounding the 10-15% performance impact from the previous Meltdown microcode patch. AMD processors are not impacted. We'll have to wait for final benchmarks for impacts in performance.

Intel Recommends Disabling Hyper Threading
The company admitted in its white paper that the software mitigations will have a significant effect on how HT works. The threads will need a higher level of isolation between each other, and they will not be able to run processes from different security domains anymore. Threads from different security domains will simply become idle (thus turning into wasted processing power).

Intel has also been publicly reluctant to agree with the disabling of HT when others have called for it with the discovery of some previous CPU flaws, but in its paper, the company stated that disabling HT altogether may be warranted as protection against MDS attacks.
Quote:
Security researchers have found a new class of vulnerabilities in Intel chips which, if exploited, can be used to steal sensitive information directly from the processor.,

The bugs are reminiscent of Meltdown and Spectre, which exploited a weakness in speculative execution, an important part of how modern processors work. Speculative execution helps processors predict to a certain degree what an application or operating system might need next and in the near-future, making the app run faster and more efficient. The processor will execute its predictions if they’re needed, or discard them if they’re not.

Both Meltdown and Spectre leaked sensitive data stored briefly in the processor, including secrets — such as passwords, secret keys and account tokens, and private messages.

Now some of the same researchers are back with an entirely new round of data-leaking bugs.

“ZombieLoad,” as it’s called, is a side-channel attack targeting Intel chips, allowing hackers to effectively exploit design flaws rather than injecting malicious code. Intel said ZombieLoad is made up of four bugs, which the researchers reported to the chip maker just a month ago.

Almost every computer with an Intel chips dating back to 2011 are affected by the vulnerabilities. AMD and ARM chips are not said to be vulnerable like earlier side-channel attacks.

ZombieLoad takes its name from a “zombie load,” an amount of data that the processor can’t understand or properly process, forcing the processor to ask for help from the processor’s microcode to prevent a crash. Apps are usually only able to see their own data, but this bug allows that data to bleed across those boundary walls. ZombieLoad will leak any data currently loaded by the processor’s core, the researchers said. Intel said patches to the microcode will help clear the processor’s buffers, preventing data from being read.

Intel has released microcode to patch vulnerable processors, including Intel Xeon, Intel Broadwell, Sandy Bridge, Skylake and Haswell chips. Intel Kaby Lake, Coffee Lake, Whiskey Lake and Cascade Lake chips are also affected, as well as all Atom and Knights processors.

But other tech giants, like consumer PC and device manufacturers, are also issuing patches as a first line of defense against possible attacks.

Computer makers Apple and Microsoft and browser makers Google have released patches, with other companies expected to follow.

In a call with TechCrunch, Intel said the microcode updates, like previous patches, would have an impact on processor performance. An Intel spokesperson told TechCrunch that most patched consumer devices could take a 3 percent performance hit at worst, and as much as 9 percent in a datacenter environment. But, the spokesperson said, it was unlikely to be noticeable in most scenarios.
Apple devices using Intel processors are reportedly faring far far worse
Quote:
The full mitigation, which includes disabling hyper-threading, prevents information leakage across threads and when transitioning between kernel and user space, which is associated with the MDS vulnerabilities for both local and remote (web) attacks.

Testing conducted by Apple in May 2019 showed as much as a 40 percent reduction in performance with tests that include multithreaded workloads and public benchmarks. Performance tests are conducted using specific Mac computers. Actual results will vary based on model, configuration, usage, and other factors.

I am really at a loss. I built a computer years ago and within the last year it started locking up randomly while watching youtube or just general usage. I had just assumed it's time was up and I bought a pre built from best buy and now that is doing the same damn thing. I have tried everything under the sun to fix this issue even down to a different HDMI cable. I'm really lost. Any ideas as to what you may think it is would be greatly appreciated. Everything is new minus the monitor and the power bar but with those im grasping at straws because they are literally the only things left that are from my old machine. Should also add I have used my accounts on a laptop I have and I have no issues.


I have now gone wireless without an ethernet cable, cause why not try it lol.

How many are contemplating switching due to Zombieload as AMD SMT is implemented more securely.

Also while Navi is nice, it isn't likely to lower pricing according to most rumors.

It's not just the security for Intel chips, it's that you get effectively the same performance for half the price at a lower TDP. That is on their top tier chip, not counting the mid range where Intel fares even worse.

AMD will lead in both single thread IPC (with the 15% IPC increase w/ Ryzen 3000 series), multi thread performance, price, security, and power efficiency for desktop and server processors for the near term future. Intel needs both the node change + core redesign for SMT security to even be competitive and their current road-map they are at least a couple of years out before both of those happen.

It's great to see AMD finally upping the stakes on Intel again. I remember building my first rig with an Athlon 64 1Ghz, which absolutly trounced anything Intel had at the time. Then came the Core series and that was it for AMD when it came to the performance crown. Wonder what Intel will do now that they finally have some competition again

Probably go back to their old playbook of anticompetitive tactics to keep AMD's market share down, then live with the slap on the wrist ($1.4 billion last time) they get for it.

I would put that it green text but I'm only half kidding....they may actually do that.

That's going to be a way tougher sell for Intel to pull with vendors this time around. Everyone has been significantly burned by Intel with Spectre, Meltdown and Zombieload. There have been Intel parts shortage that have caused industry-wide hits to vendors bottom lines (several on-going class action lawsuits) and Intel doesn't have solid answers in the product roadmaps to match AMD until the 2021/2022 time-frame.

With Snapdragon 8CX destroying Intel on the low end mobility even emulated, AMD attacking on the mid-high range with better Power/Performance/Price, motherboard vendors making bigger bets on AMD at Computex, HPE/Dell/Cray announcing Epyc server products... I have doubts those practices will have as big an effect this time around.

Not that Intel won't try like with the Tom's Hardware completely bias reporting from Computex (put out zero coverage of the ARM/AMD product launch but a glowing long Intel press piece on Ice Lake), but a lot of people will see through it this time around.

I included a highlight on products from both companies in the mid/high tier. Knowing power consumption is lower (TDP AMD measures is at full load vs TDP at intel is measured at base load AND 165W vs 105W on the top end for example), AMD IPC up to 15% better on benchmarks, AMD boards are socket compatible between generations, AMD support for PCIE 4.0, AMD pricing CPUs significantly lower than Intel, it'll be much harder for Intel to make a compelling argument for their consumer products. This is before realizing Intel needs a full core re-design to secure their multi-threading SMT architecture which will take more than a year... Intel seems only competitive in the ultra lower power space which Qualcomm will be competing with very soon.

Looking forward to benchmarks, gaming is still a top use case for my PC so individual thread performance still matters to me.

I'm hoping MSI updates the BIOS for my x370 board. AMD says performance should be the same as the new chipsets so it'll be a no-brainer to upgrade.

AMD is likely going to release the the world's first 16 core, 32 thread desktop (not HEDT) CPU with the Ryzen 9 3950x if the current leaked slide deck is real. I really wonder what the Threadripper platform CPUs are going to be like if they are already releasing a 16 core product on the mainstream desktop platform. Pricing hasn't been announced. No confirmed pricing yet, but rumor is it will be $700 USD so compared to Intel's offering.

Ryzen 9 3950X vs intel core i9-9960X
16c/32t vs 16c/32t
3.5 base/4.7 turbo vs 3.1 base/4.4 turbo
105 W TDP vs 165 W TDP
72 MB Cache vs 22 MB Cache
$700(?) vs. $1699

Benchmarks for the Ryzen 5 3600 ($200USD) vs. Intel i7-8700k($350USD) leak. Single thread performance is on par between the two with better multi-thread. I'd expect the AMD 3600X to outperform the Intel 8700K given the 5% clock speed increase between the 3600 vs 3600X.
