It decodes to uOPs optimized for the exact microarchitecture of that particular CPU. High performance ARM64 designs do the same. But in the specific case of tracking variable length instruction boundaries, that happens in the L1i cache. uOP

It isn't quite that bad. The decoders write stop bits back into the L1D, to demarc where the instructions align. Since those bits aren't indexed in the cache and don't affect associativity, they don't really cost much. A

A dual-issue in-order RISC-V isn't enough smaller than a P54c to make a significant difference. The overwhelming majority of Larabee's area went to SIMD units and caches.

There is an absolutely huge difference between a 32c/256t part and a 128c/256t part. And Tera's MTA predated the T1 by quite a bit with a similar (and evidently doomed) architecture...

How are you finding MSFS to be on Proton? I found it mostly worked, and then broke controller input about 3-4 months ago, and then partially fixed it last month. What controller or stick/throttle are you using?

Falcon 3.0 had an optional extra realistic flight dynamics model that required a x87 FPU. Probably drove some sales of the 486DX.

Oracle could do what they did with DTrace in 2017, and release it under the GPL in addition to the CDDL. Then the OpenZFS folks would have to track down every contributor to OpenZFS, and get their permission to re-license their contribution

> The Wii, when it was launched, was similar to a 10-year-old PowerBook G3, in a white box. True for the CPU, but quite unfair to the Wii's ArtX GPU, which was substantially faster and more featureful than the ATI r128 in the PB G3.

Matrox G400 (also 1999) had dot3 bump mapping as well. IIRC, they advertised it as a first in the PC 3d accelerator space, so I'd guess they shipped earlier in '99. The G400 was generally lackluster at 3d performance, so the featu

A startup I worked for during the .com bubble gave up and returned the remaining cash to investors, something on the order of 10 cents on the dollar. One of the VCs joked? that it was the best return of the year for them.
