Everything in avx is vector, even when it isn't. (below) A scalar operation would just involve a broadcast (putting the same value into all elements of the vector) then a vector operation.
All processing happens in the same area. The upper elements are just ignored in lesser operations.
If you...
I don't need a lot of tech right now but i bought some flash that I needed just because. Fear buying.
The chip plant is on the other side of the mountains. Regardless crazy leaning buildings. The fact that they didn't collapse says a lot about their building strength.
Edit: I'm disappointed in...
The later chip is has a 54w vs 35w envlope + a 50mhz bump.
Most variance will be due to the power plan of the laptop. Having a rtx 4060 makes that moot.
It was like $200 cheaper than a comprable 7840hs (zen4 54w), used savings to put in 64gb ram and a full sized 2tb faster drive replacing 16gb...
is that comic sans ?
Heat does affect resistance, but not by any measure that would change the timing in a processor. Sure at some heat point the switching frequency will fail, but until then hot or cool it's business at usual.
Go watch/read https://www.servethehome.com/ there are so many cases for quad core parts.
Especially when they include some of their edge accelerators. (QAT QuickAssist Technology compression/encryption )

It doesn't equal power per say, but in the same way watt hours != watts (we all say watts). TDP is a power limit over time.
Not all algorithms can use 100% of the cpu. Some are memory bound for example but that doesn't make them a bad benchmark.
You could say they are not a good benchmark of...
Water boils at 212F BTW but that is at sea level. More in a pressure vessel.
Imperial joules are what really matter. BTUs contain thousands of them.
Stick with the plan, there are joules in thes CPUs
I too was there at the turn of the century when intel became the gorilla. There was probably more lawsuit and trade drama then than there was during the time leading up the the FTC judgment.
intel did everything in their power to keep competitors down. Between the shenanigans trying to buy...
AVX was lacking and thusly it only lasted a couple years. AVX2 (haswell) was where things settled. Recently it was declared as the next dividing line for modern OSs x86-64-v3 (AVX2, FMA, MOVEB, bits).
protected mode - 386 (not the 286 that was just awkward) virtual memory, flat addressing, descriptor tables, etc. task segments not so much.
AMD64 - (x86-64 EMT64) moved the isa forward with very little downside if any
With standard library (std::list) and the emplace allocators of c++ only an illiterate moron would implement their own doubly linked list in c. Using free and malloc are equally arcane in modern structured containers. All joking aside, programming and hardware are different disciplines even if...
I like that layout. I've always thought they should throw some cores on the IO die or GPU. Just a quad to do housekeeping. I'm sure there's a reason not to, but I'm not qualified to answer that.
My opinion is less extra cores, more edge accelerators.
Well laid out post. My only thought is 8 p cores forevrous, at some point they have to break that cycle.
Pre-market share? That's not a thing. You can barely get a video card to run on ARM, (Jeff Geerling) and you absolutely can't on RISC-V. This has been going on for years. RISC-V isn't going to leapfrog anything, let alone catch up to ARM.
Yes use the itanium as the standard. Regardless/Irregardless IA64 was x86 compatible (to a point). Not really a port.
RISC barely competes in its own space let alone a revolutionary space.
Why? They provide a baseline repeatable operation. Moreover their simplicity makes them inheritly cross platform.
Edit: So I'm not up in 3dmark's business. But they're kind of respectable. (I looked them up) Correction really respectable. UL. Underwriters Laboratories. Their metrics and...
3dmark doesn't pretend to be anything. They make a pretty scene, it runs, it provides metrics. Whatcha See is Whatcha Get (Song by The Dramatics)
Userbenchmark is more like This is what you want, this is what you get. (song by Public Image Ltd)
Edit: Extreme overclockers seem to think it's...
Catch up? I don't think that phrase cuts the mustard. Let us look at the bread and butter.

It's has potential, but it's not going to leap frog refined technology on it's first release. In some ways it seems like...
C cores are more regular cores. Both companies used to have low power variants. (Pentium M, Atom, Geode, Bobcat, Jaguar, etc) While intel has continued two lineages, AMD has unified then diversified its cores.
Yeah. Rust hasn't been around long enough for the tool chain evolve to the level of GCC/LLVM.
In some ways it's a step in the wrong direction for auto vectorization as it is strongly ordered and typed. I didn't even know you could do instrinsics in rust till I looked it up. (introduced circa 2022)
Although I had experience with 6502, basically a kid typing in examples from magazines, I learned on a VAX. It was a good ISA. Lots of registers and virtualization.
You can basically do everything in C++ that you can in assembly with intrinsics. Compilers are darn good at producing assembly...
The FTC judgement was in 2009-10, that was very much antitrustville. Even if they stopped the kickbacks, they kept up the compiler and foundry shenanigans. Nothing happens in a vacuum, that whole era was tainted. baseball, cycling, enron, mortgage, etc.
Still going to reply.
Yeah those latencies you state are not a thing. L2 and above is local to the core. If another process needs that data, it needs to be flushed down the hierarchy. The problem with numa domains is you can have more than one location to evict data to and extra synchronization...
Did you read the article you posted? It was basically system restore and the linker fighting over a bitmap. This was a code/compiler/OS problem that has nothing to do with the hardware. The only thing the 32core processor did was probably mask the problem enough for it not to be initially...
If you watch tiny mini micro at serve the home, there are AMD offerings. If you want it to double as at TV or such computer AMD is often better. Intel just always had the right 2.5-10gbe network with usb3-4 ports, and wifi. edit: here
