Question: do those vectorize code as in the example here? I was of the understanding they performed a more limited subset of optimizations.

Some instructions are microcoded but others take the fast path and avoid the microcode sequencer. Can't patch the latter in microcode RAM.

It does not. For any of the dual CCD parts AMD has ever released for consumers. Even Strix Halo which has higher bandwidth, lower latency interconnect doesn't make a single L3 across CCDs.

It'll probably only happen when they have a singular, large die filled with cache upon which both CCDs are stacked.

Run this test if you're curious: https://github.com/ChipsandCheese/MemoryLatencyTest

Per compute die it functions as one 96M L3 with uniform latency. It is 4 cycles more latency than the configuration with smaller 32M L3. But there are two compute dies, each with their own L3. And like the 9950X coherency between these two L3 is maintained over global memory interconnect to the third (IO) die.

> 16MB L2 (8MB per die?)

It is indeed 8MB per compute die but really 1MB per core. Not shared among the entire CCD.

So do you have a lot of trust in people that "cannot hope of ever achieving a comfortable life"? It seems like a risky proposition.

>And the government did nothing.

Why didn't a private investment company, even venture capital, extend them a bridge loan? It seems like the type of technology that could have decent returns in licensing fees.

I ask this question because it seems odd to someone in the software world so flooded with startups that the government would be expected to intercede on behalf of a startup.

Unfortunately Apple is learning to be as annoying too. I don't want to upgrade to Tahoe which is inscrutable to me. Maybe remind me next year. But they pop up every week reminding me to "upgrade" even though most the problems are unfixed. They have pushed iCloud in the settings application as if it is an adboard.

Hopefully they stop but I recognize these steps from Windows slippery slope.

No. It's trying to analyze the CPU core but clarifies the device under test as that may have performance implications. There is cooling and possibly manufactured configured power limits.

Yet, unlike the Zumwalts, they are considered a good boat.

No, it was a third driver.

Per AMD

>Notably, AMD's closed-source Vulkan driver currently uses a different pipeline compiler, which is the major difference between AMD's open-source and closed-source Vulkan drivers.

Perhaps, but the percentage of Americans foreign-born is at a 100 year high. And the percentage of under 18s who have a foreign-born parent is at an all-time high (25.6% of students, the previous peak was 21.6% in 1920).

And if their children are underperforming in schools it would be important to know.

ASML has a large factory in Wilton. & Zeiss is further away from missiles. So they're less concerned about that.

Well, they're killing the animals before feeding them to the lions etc. So it won't have much of a hunting experience. But perhaps a scavenging experience is enough for them.

Note that it says they are gently euthanized first.

Otherwise I don't think there is a single horse-owner who would go through that. We have all seen what cats do with their living food.

IBM has kept researching in Albany. They license manufacturing technology to other parties even if they gave up trying to build their own fabrication facilities a decade ago.
