I said "an EC firmware hack is available for interchanging keyboards and batteries" for a reason. X220's keyboard works nearly perfectly on the X230 with this firmware hack and a slight hardware mod (insulating two LED power

I recommend getting the X230 over the X220, if anyone decides to play with these old Thinkpads. I have both machines, and I found heat dissipation has been significantly reduced on the X230 for otherwise the same performance, thanks to Ivy

Intel's 10 nm process node was ill-fated, leading to the "14 nm++++" jokes. But at least Intel finally overcame the problems and delivered 10 nm Enhanced SuperFin (now branded Intel 7) in 12th and 13th Gen CPUs with competi

They're merely rebranded Intel Core 13th Gen chips, with a performance difference around 1% at the same clock frequency. Reviewers found their CPUIDs report the same model and even stepping. Some rumors previously claimed possible mino

It seems that the CMP 170HX is being sold for $500 +/- $100 on the flea markets in China as closed mining farms are dumping any remaining inventory. Not sure if the prices are real, I'm currently trying to purchase some.

A simple improvement of the interconnect is using two rows of pin headers, one rows for signals and another rows for dedicated grounds. This should significantly reduce the loop area. I once did a quick simulation and found that even contro

I don't believe it's possible. The HBM2e chips are integrated onto the package of the GPU die, making them impossible to remove or modify in a non-destructive manner.

The use of microcode in CPUs began like this too. Originally, people replaced random logic in a CPU's Control Unit with a Mask ROM or a PLA. The goal was simply to avoid the trouble of building decoders from gates one by one. Although

Yeah, these GPUs became less appealing after the prices of 30-series GPUs have dropped. The price of SXM cards are still somewhat unbeatable though if you have a compatible server motherboard [1]. Nvidia P100s are being sold for as low as $

Waterblocks exist for some compute-only GPUs, including the Nvidia A100. Also, there are a few small vendors in China that offer mounting kits that allow you to mod these compute-only GPUs to use off-the-shelf AIO watercoolers. Certainly, n

From the picture, the logic chips are all in SOIC packages. The use of surface-mount components with 4-layer PCB should already significantly boost routing density compared to a breadboard with DIP chips. All the chips can be tightly packed
