We Saw Some Really Bad Intel CPU Bugs in 2015, and We Should Expect to See More in the Future

good thing i'm on Zylog's Z80

Effectively the performance of the isa matters little if you can make code run faster on it due to it's complexity being reduced.

E.g the compiler could generate faster running assembly code if you're writing c.

Well I think general purpose computing isn't really needed. They could simply have a specific isa to each platform that's very simple. Cheaper, most efficient and delivers consistent improvements over time

Unfortunately that's not how reality works. Those special functions exist simply because there are inefficiencies in a simpler ISA.

It affects Ciscy isas.

To what extent I don't know.

I'm no expert on IA32 by any means.

PowerPC is RISC.

Will we see more cpu bugs than bugs in a ubisoft game?

[Master Disaster]

Correct me if I'm wrong but isnt 10nm the smallest manufacturing node we can reach on Silicon?

So then doesn't that mean that in less than 5 years both Intel & AMD are going to o have to ditch everything and start again? (Obviously they'll continue to manufacture 10nm for the foreseeable future)

And isn't that going to cause them some major headache? I mean writing the entire microcode from scratch for an entirely brand new architecture must be more challenging than writing for a node shrink?

So basically things are only going to get worse in the future?

Lol 3930k FTW

Ivy bridge FTW !

 

Sure you don't mean Sandy Bridge?  IIRC Ivy were the ones that required delidding if you wanted to use the CPU for something more demanding than solitaire. 

 

Joking aside, I was having a hard time choosing between X99 and Z170.  With all this bug nonsense, methinks I'll stick with my 2500 a bit longer.

Derek Michocka at emulators.com has been talking about stuff like this and the switchover from x86 to whatever the future will be, for years. A lot of people in the industry talk about more flexible and basic low level arch and the use of hypervisors, binary translation, or jitting to run legacy code on future hardware, ameliorating the pains of leaving x86 behind.

 

There is a LOT of stuff to read through on the site, much going back to P3/4 and Core M days, but a lot of interesting nuts and bolts info on these subjects.

I personally think we will because they think AMD is no threat until AMD gains a 55% market share they will keep being lazy...

ACTUALLLLLLLLLLLLLLLLLLLLLLLLLLLLY  expect this from most companies now, just about everyone is cutting down on any testing personnel so get ready to see this from EVERYONE
