Even regardless of security issues, Ryzen is offering an insane price/performance ratio. For anyone using applications that benefit from extra cores, AMD is the only sensible choice right now at most price ranges.
Where does Intel have the edge? Benchmark programs that test specifically single core speed maybe?
One of the Intel optimisations in question, leaps ahead and executes instructions way before they are needed. Trouble is it leaps ahead and loads data which is sometimes sensitive, and leaves it there in the open for the other process on the core to see! The attackers could spy when passwords are loaded into memory, say when a user is logging in as root (administrator), then in the other process on the core, read that memory, before the processor had a chance to clean it up. Boom - the other process, i.e not the legitimate one which is loading up your password file, can now see your password.
The two processes on the core also store some temporary data in a shared cache. Here’s the thing about processor cache: by loading data from the cache and timing it, the time it takes to load tells an attacker what has recently been cached. So again the attackers could run a nasty little process which while a user is logging as admin/root, looks at the cache entries, and see what has recently been cached. This process knows that if the user is currently logging in, and there are some very responsive cache items, they are probably filled with sensitive information.
So you can see how Intel were cheating by muddling up sensitive data of privileged processes with regular old processes. This is hard coded into the design, very hard for them to escape. My predicition is a slow decline and carve up, a la HTC.
Yeah and this is great news for TSMC. If they can force Intel to divert spending from fabrication to design, TSMC will have the whole CPU market.
The smart thing for Intel is to merge their fabs with Samsung. Tough pill to swallow but I don’t see any other viable options.
Jesus Christ, I knew AMD was gaining a lot of market, but Intel is actually getting assblasted.
Hopefully AMD will not become greedy and follow Intel’s pricing “”“strategy”"".
The mobile market (tablets and laptops) is what i’m really looking forward to, because currently AMD offers good performance, good price and low power consumption. It’s ideal for mobile products, we just need more manufacturers to shy away from intel.
Every time that Acer, Asus, Lenovo etc show a new laptop on social media, we should have a million bots replying:“Oh wow this looks great! If it had an Amd cpu I’d preorder right now!”, or something along those lines.
