Re: Who is left

Back when Celeron 300As ran at 450mhz. And Intel hated it. Mendocino Celerons were more of a happy accident. Intel was experimenting on trying to add on-die L2 cache. They were resulted, because they only able to cram 128KiB of it on 250nm node. Intel marketing branded them as "Celerons" ...

Shift that a bit - Haswell/Broadwell and Skylake/Kaby Lake/Coffee Lake should have moderate impact. Westmere should have similar (higher) impact to Ivy (and Sandy) Bridge, because it has PCID. Nehalem and earlier should have very high impact, not having PCID. Also, I've seen a claim (but it was on H...

In the sense that it's being used here, "speculative execution" really means "branch prediction". (Nowadays it's often used to mean "execute both sides of the branch", but it used to just mean branch prediction 20 years ago, and I don't think anyone's actually doing it ...

On 366s, it usually required some more voltage - 2.1-2.2 V usually, stock being 2.0, as Mendocino didn't like going much over 500. My pair of 366s crashed quite quickly at 550 @ 2.0 V. Tonight's project was going to be cranking it up to 550, but the motherboard had other plans. Now, 300As or 333s, o...

Surprisingly snappy for how slow they are (they're 366s), and that was with the Chromatic Mpact2, which was using VgaSave.

Although, I need to try for Win7 once I get the board resurrected.

There are actually benefits to AWD for fuel efficiency in hybrids and especially electrics, if it's a dual or more motor setup - better control of regenerative braking, and especially on electrics, potentially better optimized gearing for efficiency - but for straight ICE, yeah, no.

That would help, although the highest-power system I'm aware of for this is KAIST OLEV, at 100 kW. A good supplement, but you'd still need to spend time at low speed or stopped to charge. Also, in the context of endurance racing, the crown jewel of endurance racing is the 24 Hours of Le Mans, and mu...

In the case of an LMP-style electric, I'd put the battery where the engine used to be, and extend forward beside the driver. (Note that every LMP1 hybrid has had the energy storage beside the driver.) So, it'll be fully forward of the rear wheels, and you could just lift a bodywork section, and pull...

The problem with the NIO EP9 record is that it's not even a street-legal supercar. Somewhere I've seen someone pointing out that it beat the Pagani Zonda R, but if you're including street-illegal cars, that's not the car to beat . The car to beat would be the Porsche 956, which set a 6:11.13 on the ...

Re: VME Broken on AMD Ryzen

That's AMD's full chipset driver package, though, for all platforms. That doesn't say anything for what Ryzen supports. And, Ryzen isn't compatible with Windows 8.1 either - Microsoft made the call that 8.1 won't get Kaby Lake, Bristol Ridge, or Ryzen support, even though it's in mainstream support.
