because they're basically all defective, and being discontinued is even more reason to purge all affected CPU inventories.

i mean, I don't care personally if people want to spend $400 on an old chip that's going to be gimped anyway, but MSRP on sealed processors should have huge price cuts

Who would be giving them away? [...] Why should the current sellers give the chips away?
I assume ExcellR8 means they should be "given away" at Intel's and AMD's expense, but in any event, good luck with that...

You don't have your cake and eat it too: either these parts are problematic (security risk) in which case they should all be purged from the market, or they're ok all things considered (performance drop) in which case the market sets the price (offer vs. demand).

What next after these discounts?! Call for vendors to produce them some more "cuz retail prices still not going down, demand too strong"?

I read it as it should as in the market will likely put pressure on these making the MSRP go down.

It won't, supply is low enough to begin with, how else do you imagine these prices continued to exist after Intel effectively increased their core count by 50% for the same price?

Even the DRAM market is likely to influence old CPU prices, since the memory price hike is making many reconsider keeping their old DDR3 based platform for just a bit longer.

I did not say I agreed, but it does make your response seem to be incongruent with that reading.

Intel now opts to let their customers test the (Skylake only) microcode for them.
We also continue to release beta microcode updates so that customers and partners have the opportunity to conduct extensive testing before we move them into production.
https://newsroom.intel.com/news/security-issue-update-progress-continues-firmware-updates/

Isn't that completely backward? Shouldn't Intel conduct extensive testing before customers move them into production?

Isn't that what Linus (the real Linus) was throwing a tantrum about. Basically Intel putting the pressure and work onto everyone else for the solution even so far as to make the security implementations an opt in instead of default?

This is just sad that things like this have to happen. I do not know how these fixes and patches are going to affect my laptop.

My laptop runs on a intel i7-4500u cpu. What effect will the patches or fixes will have on my laptop if any?

Amol, Very little. Chances of you running anything that will see more than a single digit (if that) drop in performance is unlikely. The patches impact I/O type of work which impact things like SAN's and VM servers. Most client software is barely affected.

Dude they were discontinued way way before meltdown.

okay, thanks dude bro dog. I don't see what being officially discontinued by Intel has anything to do with why older chips are still for sale online at ridiculous prices. sure, you don't have to buy them (and why would you?) but if they aren't fixable so I'd consider that selling defective goods--no matter if the vendor doesn't care to support them anymore. Broken is broken.

I don't expect retailers to take the hit for the vendors' mistakes but at the same time Intel stating that "oh sorry, we'll do better next time" and then seeing all of their affected chips that are still on the market at normal prices. If these were cars, people would be burning dealerships to the ground if they weren't marked down.

I think your thought process is way out of alignment of the real world. I get why you are saying what you are saying. But unless you mean not buying the products you are selling when you say burning to the ground then you are wrong. Legal for safety concerns this doesn't happen to cars because the government forces them to fix the issue and for a company like VW actually offer refunds on the car.

But realistically if a CPU is still on the shelf long after the CPU goes discontinued it's up to the retailers to handle whatever discount they need to clear shelves. Problem is that semi recent to semi old hardware has a demand that increases every year as critical systems run into issues and need replacement parts. This demand doesn't soften because of the exploit. The only real question is the cost of the part vs. The cost of switching systems.

uh, no kidding. my point was if the governments just let the defective cars be sold without any actual fix, and for the regular asking price, people would be upset. this obviously doesn't apply to computer processors (which aren't automobiles) but the concept is the same... i.e. selling products that don't work as they should, which some would argue is the definition of defective.

They work exactly the way they were designed. It just turns out that the design is susceptible to a particular kind of attack. So the analogy doesn't really work.

Actually, now that I think about it, the VW "fix" also reduced performance. So never mind. The analogy works in that sense.

Again the point of the VW portion was actual public safety and not just doesn't work like we thought it did. It also was a malicious move by VW. They also couldn't sell cars with the issue any more. But it's specifically because it is cars and those are regulated because of physical dangers that it happened. So people getting a discount on the sale had to do with VW dealerships and VW themselves trying to make sure sales didnt drop off to much.

This doesn't in anyway apply to the general electronics or most other physical product out there. What you are looking at has nothing to do with digital safety, or performance. It has to do with supply and demand for an out of production product that has needs in many companies system critical hardware.

Let me rephrase my previous posts, I feel like I didn't get my point across (whether we agree or not, that's another story):

For discontinued products, even if Intel discounts them to just $9.99, my opinion is they are still going to end up in stores at prices mostly similar to what we have today due to high asymmetry between offer and demand. Memory prices alone have skewed the market to an unbelievable extent. (the closest analogy would be GPU mining bonanza, where vendors did not change MSRP yet prices exploded)

Actually, now that I think about it, the VW "fix" also reduced performance. So never mind. The analogy works in that sense.
The emission "fix" reduced performance with no further improvement in sight. The current software fixes are considered best effort, they are expected to be followed up by better implementations, with (hopefully) considerable lower performance penalty.

Of course, should Intel have focused on communicating properly instead of behaving like a see-no-evil monkey, we might have had a more clear picture on the matter, not just assumptions and reddit threads like this one that may or may not bring actual good news.

That's exactly what's happening with diesel cars in Germany, no fix (even though it's technically possible and feasible), no reduced prices, but you can get rebates when you can turn in an old diesel car (but even that is running out). Since 2012 German cities are being pressured by courts to enact temporary bans on driving whenever pollution is too high (which happens regularly) which they still ignore to this day, politicians pretend the issue doesn't exist aside claiming there won't ever be a ban on driving, and the car industry is happy to let upset drivers complain about the possibility of bans on driving instead fixing the very cause.

The government requires "defective" parts of the car to be fixed. They certainly dont require the manufacturer to lower prices, as it seems you are thinking they should do. In fact, in the US at least, it would be highly illegal for the government to fix prices.

No, I don't think so. There is a wide variety of workloads out there. In this case I think it's a great idea to let the customers participate in the testing and refining of the patches.

Just realized that Meltdown is more than just side-channel attack. Intel MMU is also faulty, it make unauthorized page transitions.

Side-channel triggered speculative read to any address will result both TLB and corresponding cache line to updated. What the fuck Intel - ain't it mandatory anymore for MMU to check privilege levels when doing pagewalks, and update TLB only if check passed? Optimizing TLB checks have performance properties but what is excuse for skipping checks even with MMU transitions?

Make Intel replace all faulty CPU'S.
Yes, I want to see Intel (and AMD) start re-making all the old chips again...and shipping them out to all the customers who have "faulty" chips.

I wonder who'd go bankrupt first?

well, there's like, 10 people that still run those old AMD chips that are actually effected.
