Sure, but to write 1GB you stream 1GB from ram -> CPU in either case. With software RAID you do the calcs (60GB/sec per core) and then write 1.3GB/sec to the storage controller. Just doesn't seem that much of a differenc

The difference isn't that big though. Sure with software RAID you write 1GB to a 8 disk RAID6 you write 8/6 x 1GB = 1.33GB. But with RAID offload you nearly double the NVME bandwidth (n - 1) x 2 consumed. I also wonder, if you h

Seems like quite a bit of complexity for a dubious win. Today's CPUs are REALLY fast, even a single core of 64 or more cores that are common on servers today: [ 478.047970] raid6: avx2x2 gen() 60473 MB/s [ 478.115971] r

"AMD Strix Point expected to debut in October, claims AOOSTAR" was a new headline I've seen. Seems about right that laptops (higher margin parts) land a few months before the SFFs. I'm excited about the strix halo that

Keep in mind a 2 cycle tiny engine puts up 75% or more of the energy as noise and heat. Modern brushless electric motors are 90% or more efficient. Gas is more dense for sure, but not as much as the energy difference. There are other savi

Apple used to represent a small fraction of Intel's volume, but a large fraction of Intel's profit. Which is gone. Cloud providers used to buy mostly Intel servers, but now have various efforts on buying or making their own CPUs.

They had a great plan, that was promising, and Intel was focused entirely on the pentium-4, which had high clocks for bragging rights, long pipeline (related to the high clocks), and high power usage. However between Transmeta's idea a

AMD/Intel CPUs for desktops/laptops are mostly 128 bit wide. So these days on laptops (no DIMM slots) is DDR5-6400 = 102GB/sec peak to DDR5-8000 (128GB/sec peak). Apple however has 192 bit (m3 pro), 256 bit (m2 pro), 51

Various corps have been lobbying for the NOAA to stop providing weather info directly to the public, so that it can be more efficiently (read that as monetized) distributed. Seems pretty evil, since the vast majority of sat based and radar

Sort of. It's not just efficiency that's lost, but peak power. But if peak power was causing the CPU problems it wouldn't get better with a replacement CPU. Sure power supplies provide accurate power ... till they can'

Varies by brand, some use better parts. I've definitely seen file servers that won't boot after 3 years, then I pull a few drives to lower the power needed and it boots. After another year or two I have to pull more drives. Even

Sure, that might explain it, except when people get replacements things are improved, but then start getting worse. Some even are on their 3rd CPU. What's making news is that Intel is starting (in at least one case) to deny RMA replac

Cars per mile, yes. Cars per second no. If you follow the recommended 3 second spacing then it's a car per 3 seconds per lane. So for a fixed distance, the slower you go, the longer you are on the road, the more road capacity you con

Sure. But now you have to spend more money on adding lanes for the same traffic capacity because the average speed drops.

Very distant objects need very little speed to orbit, take for instance a geosynchronous orbit that orbits every 24 hours, which enables it to hover over the same part of the equator indefinitely. With a braking burn from geosync orbit your
