Lots of motorcyclists replace their lead-acid batteries with lithium-ion batteries that are much lighter. They’re very unreliable but some people will deal with that to save a few pounds.
I imagine you mean ice cars with much more demanding starters, but worldwide motorcycle market is pretty big.
It's a good thing you measured it :-) Programs that do a little bit of 512x512 FMA mixed in with other stuff will not benefit from AVX-512 but can suffer from the heat it generates, or from the hiccup when the CPU turns the FMA unit on and back off.
Codes that can do a lot of 512b FMA consecutively will benefit very greatly, and pay a small penalty (up to 25%) in terms of throughput for everything else.
Codes that use non-multiplier stuff that's just marketed as AVX-512, like VBMI2, also benefit greatly and without any penalty.
People with AMD CPUs don't get a choice. Hard to see how this accrues to Intel's mistakes column.
"Just the board" NUC kits also include the CPU, case, fan, power supply, wifi, bt, etc everything except RAM and storage.
It is a major problem to figure out what instructions to use but it's a lot more nuanced than you seem to imply. In the first place you seem to assume that "not running at the max turbo speed that's printed in the marketing literature" is equivalent to "downclocking". However, there are a huge number of reasons why a core might not clock up, including the number of active cores on the package. The first Xeons that shipped with AVX-512 had turbo clocks that were 25% lower than the headline turbo clocks, e.g. 2400MHz instead of 3200MHz. This is still pretty good, and the base clock is 2100MHz.
With the newest Ice Lake processors ("10th generation") the all-cores-active, all-avx-512 max clock speeds are the same as max scalar clock speeds. You can try this out yourself with the avx-turbo program.
Basically all that stuff you said about IoT has been said verbatim for decades and yet here we are. Remember the "SmartMote"? Neither does anyone else. By the way that was _also_ an Intel-funded project.
Have there been any published benchmarks of relevant datacenter workloads on this CPU? I certainly haven’t seen any. The previous generation EPYC was really slow on branchy code, despite looking ok on ffmpeg benchmarks and the like.
ARM has never enjoyed a Op/J advantage over x86. They have low-power designs, yes, but they don’t do more work for a given amount of energy.
x86 won fair and square. The risc people failed to foresee that instruction density would be extremely important to performance. Intel didn’t beat them with physics. CISC is just fundamentally better.
This comment seems kinda slanted. AVX-512 debuted on Xeon because datacenter operators asked for it. It does not “downclock a whole chip”, it gates the core where it is active and there’s not even that penalty on the current generation parts. “10nm” is marketing fluff which has little or nothing to do with actual semiconductor construction. “Chiplet” is also marketing-speak for “wow this memory topology is hard to program around “. Not sure they should feel too bad about missing that boat.
What Intel really should be worried about is the client side being their largest revenue segment. That’s a dead business, eventually. And the bets they made didn’t pan out: FPGAs aren’t popular because the people sophisticated enough to use them are also smart enough to tape out ASICs. IoT is not a thing.
The senior project is the one I mentioned that can be fulfilled by CS210, working at “our industry partners” in lieu of actual university coursework. The “tech & society” catalog is a joke. Look at the courses. Archeology? Fine as an elective.
My engineering program required an upper-division course from the philosophy department on the development of rigorously ethical systems of thought.
I'll never have personal first-hand experience with another kind of degree program, but my engineering program taught thermodynamics, accounting, technical writing, and ethics. I am looking right now at the Stanford CS undergraduate catalog and there are no requirements for technical writing, ethics, etc in here at all. Even the senior year writing requirement can be satisfied by working for Facebook for six months, which is disturbing and, frankly, explains a lot about why these kids can't write.
Huh. Thanks! I really missed the memo there. I wonder why 1035 doesn’t mention that it is updated-by 1123.
I don’t think I’m assuming that. They’ll just be a more rounded person.
I'm just giving you the straight dope on a few aspects of the organizational disaster that is google. The fact that you think it's incredible etc just shows what a basket case this company is.
As a person without a CS education but with 30 years of industry experience, including several of The Bigs, I urge young people to get an education in anything but CS. The number of CS degree holders, even the masters and doctors, who struggle with statistics, linear algebra, or even thermodynamics and basic accounting is pretty dispiriting. Get an education and learn to program computers. Two separate things in my humble opinion.
Perhaps the app can manage to remember your address and phone number, instead of making you type it in every time even when you are logged in to your account? I dunno just guessing at some improvements they can make.
I find that Nextdoor gets me more responses on for-sale items and none of them are scams. On Craigslist I get fewer and the majority are scams. I only bother with Craigslist these days when I’m looking to buy, or if I’m selling an item expensive enough to worry about getting the best price.
After I switched from SRE-SWE to just SWE, my team (of six SWEs) used IRC and it wasn't because of my influence, either.
Googlers also use it for the daily chat, not just incident response.
Decimal floats are a lot older than COBOL. Many early relay computers (to the extent there were many such machines) used floating-point numbers with bi-quinary digits in the mantissa. https://en.wikipedia.org/wiki/Bi-quinary_coded_decimal
When did RFC1035 get thrown under the bus? According to it, with respect to domain name labels, "They must start with a letter" (2.3.1).
We've already spent the money on the transportation and forgot the upzoning that should have accompanied it. For example we poured billions into BART to serve dispersed areas full of detached single-family homes. All areas within half a mile of a BART station should permit 5-story multi-family dwellings without mandatory parking. This was the point of SB50.
Micro apartments are a straw man. The zoning codes all over California prohibit duplexes and triplexes, including over 85% of the area of the supposedly dense city of San Francisco. We don’t need weird innovative forms. We need the old forms.
I believe the point was that GaN semiconductors make these chargers more compact, cooler, and lighter than their silicon competitors.
