Zombieland impact on Intel CPUs

[keyser]

About 1-2%

So how badly have all these vulnerabilities affected something like the 9900K in gaming ?

With all the mitigation’s you drop hyper threading so that alone would be 20-30% I’m not sure what the rest of the fixes cost, as some have been applied pre launch so it’s hard to say what the total cost would be. Another unknown factor will be all the middleware fixes.

So the i9 actually gets Hyperthreading disabled or it's optional ?

not every patch well the major ones have hit the 9700/9900k though they did have a lot of fixes built in so i doubt atm those cpu have had much of of a performance hit well untill the new ones get found ofc

The performance hit from these countless vulnerabilities and their subsequent patches must be significant.

What's shocking is Ryzen 3000 was benched against Intel systems without any of the performance crippling patches applied (or the latest ones) in all the reviews I've checked. The reviewers either outright said they did not test with the Intel patches or they didn't mention it at all.

most if not all reviewers who are on intel lsit for reciving press samples will do testing without patches aplied U can bet that intel has now made it part of there agreeement with them why showq the cpu in a bad light when your giving them the stuff for free and before launch intel are one odf those compainies that would leverage that and peopole who dont follow dont get press samples amed would do the same also though and im sure thery do with the patches that increase stuff like that scheduling patch, allwyas get to show your own product in the best light and thats forcing reviewers to remove patches that nerf perforamcne and to keep patches that improve it.
scheduling

One of the most upsetting part of these recent Intel focused CPU attacks is that Intel (in some cases) was informed and did nothing or argued that the exploit was not worth patching. This probably due to the impact on performance the FW level patches would have, mainly on the server market.


This is definitely one of the advantages of having the choice of 2 strong CPU makers again, you can now go for who is the most secure at the time of purchase without any real performance hit.

intel knew about most of the exploits and hacks but chose not to do anything about them its simple buisness why worrie about something that mgiht not get found and even on most people pc's the exploit and hacks are mainly slim to be used against you I get that server cpu and company pc's security need to be more of a concern but of most of the exploits and hacks found none have really worried me with my own pc though. beofre i mosved to amd anyhow.

But we only really have 1 stong cpu maker though and that is intel. Intel had such a market dominance over amd and even before amd struggled and brought out the failed fx proccssors when amd match intel intel still sold more.
look at the numbers today yes amd is gainingh market share but not at the alarming rate it sould do though. amd sderver cpu is better then intel atm and cheaper less power and more powerful but companies are slow to movew to amd either though software being heavly optimised for intel or just the fact intel have a much better rap then amd does in that sopace amd whilst better are still struggling to make a dent into intel dominance.

as for custiomer pc delll hp etc still heavly favor intel same as most pc makers soo many more intel system then amd and so many mre options for your budget. look at the custom pc buiilders for intel and amd system again same story that inetel get so many more option and amd dont seem to get as much of lookin and so many places like to put amd cpu with amd gpu which is also annoying as amd grpahic is quite far behind nvidia when it comes to high end parts so selling a 3900x system with a 5700xt doesnt make much sence vs a 9900k and a 2080ti lets say.

amd are selling very well in the custom build market though and have taken the fight to intel but that market is small comepred to prebuilds and laptops and to the avarage person My dad or your nonm techhy naubour intel are a aa trusted brand and the only one that most people will loook at

whilst in perfoamnce terms and what amd have done with ryzen is impressivbe and there are 2 cpu makers to chose from but in the markets that matter intel are currently the only real player in town . i

It’s the only way to cure some of the flaws in hardware.

 

[hyperseven]

That an advantage of AMD, their market share is just too insignificant for hackers to bother finding exploits in

Am I correct in thinking if you downgrade a Bios the the microcode version will be what ever comes with that Bios version

When I flash my MSI motherboards with previous BIOS versions the microcode is also downgraded.

Some motherboard manufacturers don't allow downgrading. ASRock shows a warning for each BIOS version that is an one-way upgrade: "*User will not able to flash to previous BIOS once upgrading to this BIOS version."
