This keeps getting slightly misrepresented.
There is no fix for CPUs that are already damaged.
There is a fix now to prevent it from happening to a good CPU.
But isn’t the fix basically under clocking those CPU?
Meaning the “solution” (not even out yet) is crippling those units before the flaw cripples them?
They said the cause was a bug in the microcode making the CPU request unsafe voltages:
Our analysis of returned processors confirms that the elevated operating voltage is stemming from a microcode algorithm resulting in incorrect voltage requests to the processor.
If the buggy behaviour of the voltage contributed to higher boosts, then the fix will cost some performance. But if the clocks were steered separately from the voltage, and the boost clock is still achieved without the overly high voltage, then it might be performance neutral.
I think we will know for sure soon, multiple reviewers announced they were planning to test the impact.
That was the first “Intel Baseline Profile” they rolled out to mobo manufacturers earlier in the year. They’ve roll out a new fix now.
Remember Spectre? When they recommended disabling hyperthreading?
Not out yet. But you can manually set your clocks and disable boost.
Not out yet.
Actually the 0x129 microcode was released yesterday, now it depends on which motherboard you have and how quickly they release a bios that packages it. According to Anandtech Asus and MSI did already release before Intel made the announcement. I see some for Gigabyte and Asrock too.
AMD fans be like:
you know, im kinda a pc fan myself…
Ugh. Can I just say how much I fucking HATE how every single fucking product on the market today is a cheap, broken, barely functional piece of shit.
I swear to God the number of times I have to FIX something BRAND NEW that I JUST PAID FOR is absolutely ridiculous.
I knew I should’ve been an engineer, how easy must it be to sit around and make shit that doesn’t work?
Fucking despicable. Do better or die, manufacturers.
For CPUs nothing beats AMD
For years, Intel’s compiler, math library MKL and their profiler, VTune, really only worked well with their own CPUs. There was in fact code that decreased performance if it detected a non-Intel CPU in place:

That later became part of a larger lawsuit, but since Intel is not discriminating against AMD directly, but rather against all other non-Intel CPUs, the result of the lawsuit was underwhelming. In fact, it’s still a problem today:

Given that the MKL is a widely used library, people also indirectly suffer from this if they buy an AMD CPU and utilize software that links against that library.
As someone working in low-level optimization, that was/is a shitty situation. I still bought an AMD CPU after the latest fiasco a couple of weeks ago.
Honestly even with gpus now too. I was forced to team green for a few years because they were so far behind. Now though, unless you absolutely need a 4090 for some reason, you can get basically the same performance from and, for 70% of the cost
I haven’t really been paying much attention to the latest GPU news, but can AMD cards do ray tracing and dlss and all that jazz that comes with RTX cards?
Yes, but by different names. They use FSR that’s basically the same thing, I haven’t noticed a difference in quality. Ray tracing too, just not branded as RTX
DLSS is off the table, but you CAN raytrace. That being said I do not see the value of RT myself. It has the greatest performance impact of any graphical setting and often looks only marginally better than baked in lighting.
It depends greatly on the game. I’ve seen a huge difference in games like Control where the game itself was used to feature that… Well… Feature! You can see it in the quality of the lighting and the reflections. You also get better illumination on darker areas thanks to radiated lighting. It’s much more natural looking.
dlss is a brand name both amd and intel have their own version of the same thing, and they are only a little worse if at all.
Ryzen gang
My 7800x3d is incredible, I won’t be going back to Intel any time soon.

To put this into context, the zen5 X3D chips aren’t out yet so this isn’t really an apples to apples comparison between generations. Also, zen5 was heavily optimized for efficiency rather than speed - they’re only like 5% faster than zen4 (X series, not X3D ofc) last I saw but they do that at the zen3 TDPs, which is crazy impressive. I’m not disagreeing with you about the 7800X3D - I love that chip, it’s def a good one - just don’t want people to get the wrong idea about zen5.
I’m still staying with my 5950X. So many cores!
Also on the 7800X3D. I think I switched at just the right time. I’ve been on Intel since the Athlon XP. The next buy would have been 13/14th gen.
is still on the atom n270
Me who bought AMD cpu and gpu last year for my new rig cause fuck the massive mark up for marginal improvement on last gen stats.
tldr: Flaw can give a hacker access to your computer only if they have already bypassed most of the computer’s security.
This means continue not going to sketchy sites.
Continue not downloading that obviously malicious attachment.
Continue not being a dumbass.
Proceed as normal.
Because if a hacker got that deep your system is already fucked.
Don’t be a fan of one or the other, just get what’s more appropriate at the time of buying.
I switched to AMD largely for better battery performance, but this mades me feel like I dodged a bullet.
Intel has not halted sales or clawed back any inventory. It will not do a recall, period. The company is not currently commenting on whether or how it might extend its warranty.
They may be greedy but they are not stupid. Clearly they calculated that by just ignoring the issue and eating the lawsuits, they save money compared to trying to make an actual solution (whatever that would even look like in the first place)
Gotta love fucking over the consumer twice! They’re gonna get, what, $5 out of a class action? $5 and a burned out cpu, yay!
I thought the point would be a depressed and self deprecating “I’m something of an Intel CPU myself”.
Glad my first self-built PC is full AMD (built about a year ago).
Screw Intel and Nvidia
7700X is what it was built with
im a fan of no corporation especially not fucking amd, but they have been so much better than intel recently that im struggling to understand why anyone still buys intel
Of all the CPU and GPU manufacturers out there, AMD is the most consistently pro-consumer with the least corporate fuckery, so I take mighty exception at your ‘especially not fucking amd’ comment.
Researchers discover potentially catastrophic exploit present in AMD chips for decades
They’re both very flawed
