Sort of. Random writes are fine as long as they are as large as the physical write block size (not the virtual 512b or 4k) and there's a queue depth high enough to keep the drive busy. Unless you are lucky enough to have Intel's

In my experience, after handling many dozens of systems (out of 3000) with ECC errors, it's quite rare for the problem to be reproducible in memtest86. Running in production often triggers many errors per day. Our alarm threshold is

Not sure what it is about memtest86, but in my experience it doesn't find most memory errors. I've had serious memory issues, that trigger memlogd, dmesg, or similar about EDAC/ECC errors. I try memtest86 over night, no err

There have been numerous attempts at GPU friendly memory systems for CPUs. Iris Pro had an off chip, but inside package help. I forget if it was cache, ram, or edram. The current apple solution looks like the best I've seen (100,200

Grace + Hopper is very similar to a 4090 + CPU. They are each on their own die/chiplet, but share a package. The CPU will of course be ARM not x86-64, but otherwise very similar to what you describe.

More like 2x. Apple for instance uses lpddr5 for 100, 200, 400, or 800GB/sec. It's mostly bus width, not the memory technology that makes a big difference.

Keep in mind that PC sockets have very little memory bandwidth. Even the fancy new AM5 socket with DDR5 and the "recommended" overclocking to DDR5-6000 leaves you with 96GB/sec. Even the lowly RX 6400 has a dedicated 128GB&

Normal cars are designed from wide temperature ranges (something like -30F to 130F), -100 to 14k feet altitude, with a wide range of sand, dirt, snow, ice, hail and a wide variety of roads surfaces and steepness. Generally they seem design

Sad. Bluray sounds and looks better than any video streaming I've seen. Never look for compression artifacts, you'll never be able to enjoy highly compressed streaming again. I got a LG C1 tv, upgraded netflix to 4k streaming ..

Say a power plant is 50 miles away. There's substantial cost running the grid 50 miles, buying the contiguous land, building high voltage towers, the copper, the maintenance, the substations, etc. Thus the delivery cost is huge and t

Because generators aren't paying their fair share of the grid, a chunk of their power is wasted on transmission losses, etc. If I make 10kw with solar on my roof and someone else in my neighborhood uses it it makes the world a better p

It's really simple. Every grid user should pay retail price for power at the spot retail price when they buy it from the grid Every grid user should be paid retail price for power at the spot retail price when they send it to the grid.

Stupid wide? Pins, memory controllers, and traces (and layers) on motherboards aren't cheap. Apple just decided that the paying memory bandwidth was worth it. Is there some reason why you think the extra memory bandwidth was stupid?
