undersuiton xAI is looking more like a datacentre REIT than a frontier lab

So little of that is going to happen.

The DDR5 will be registered DIMMs. The GPUs will be 600W paperweights with a custom form factor. Similarly the NICs and other PCI-E accelerators. The motherboards also adopt custom form factors to fit in racks. The hard drives will be using SAS connectors. The flash will be in E1.S form factors.

The server CPUs that you want for a home desktop or small server, high clock SKUs, will be in high demand.

Any savings for someone willing to build a system from second-hand server hardware will be eaten by using adapters or sourcing a rack.

I'm not saying you won't be able to make a slightly outdated frankenserver with more compute than you need, I'm saying that's not going to bring down prices for Grandma's machine that she needs working to check on her retirement account.

I would guess that there is an issue when the USB peripherals connect and disconnect as you switch inputs. I don't put USB drives in my KVM because it'll interrupt a transfer if switched.

undersuiton New 10 GbE USB adapters are cooler, smaller, cheaper

The big bulky black box this little adapter replaces in Jeff's uses is actually just a PCIe/OCP card in an enclosure and you can replace that with a 10g card with SFP.

undersuiton AMD's Ryzen 9 9950X3D2 Dual Edition crams 208MB of cache into a single chip

AMD didn't have to introduce a special driver for the Ryzen 9 5950x to keep threads resident to the "gaming" CCD. There was only a small difference between the 5950x and the non-X3d Ryzen 7 5800x in workloads that didn't use more than 8 cores unlike the observed slowdowns in the Ryzen 9s 7950X3D and 7900X3D when they were released compared to the Ryzen 7 7800X3D .

When the L3 sizes are different across CCDs the special AMD driver is needed to keep threads pinned to the larger L3 CCD and prevent them from being placed on the small L3 CCD where their memory requests can exploit the other CCD's L3 as an L4. The AMD driver reduces CCD to CCD data requests by keeping programs contained in one CCD.

With equal L3 caches when a process spills onto the second CCD it will still use the first's L3 cache as "L4" but it no longer has to evict that data at the same rate as the lopsided models. Additionally the first CCD can use the second CCD's L3 in kind reducing the number of requests that need to go to main memory.

The same sized L3s reduce contention to the IO die and the larger sized L3s reduce memory contention, it's a win-win.

Improving LLM memory contention will allow LLMs to use more memory.

I'm an advocate of sticking a $5 16Gb Optane stick from eBay on a $10 M.2 to PCIe 1x adapter from eBay. Set it up as swap in Windows or Linux. Or pay $200 for a 16GB stick of DDR5.

ECC is actually slower. The hardware to compute every transaction is correct does add a slight delay, but nothing compared to the delay of working on corrupted data.

undersuiton Data centers in space makes no sense

Article doesn't say the satellites stop working in their dark phase, it says they consume 300W in the dark phase based on some battery math.

undersuiton Data centers in space makes no sense

The solar panels on the newest satellites can deliver 6kW but the power that satellite actually uses is less. The satellite is only using 300W[1] during the dark phase of it's orbit when it can use it's entire mass to cool down. Is that limit because of the battery or is it because the satellite needs to radiate all the heat it acquired from the other half of the time in the sun?

undersuiton Reliable 25 Gigabit Ethernet via Thunderbolt

PCI-E lanes for consumers. Gigabit would saturate the PCI bus, but once you're on PCI-E you only need to give it 1 lane, usually off the chipset.

Servers had a reason to spend for the 10G, 25G and 40G cards which used 4 lanes.

There are 10 Gigabit chips that can run off of one PCI-E 4.0 lane now and the 2.5G and 5G speeds are supported(802.3bz).
