    Asus announced a 17" 16:10 narrow-bezel laptop workstation with a centered keyboard. The numpad shares spaces with the trackpad which unfortunately lacks physical buttons.

    This NeurIPS talk by is blowing my mind! I don't think I can summarize this in a tweet except that biology has come a long way.

    64 entries are for 4K pages, which is 256K. If you use 2M pages, you get 8 entries, or 16M. With 1G pages you get 4 entries or 4G. So the lesson is: use bigger pages if you can!

    Had a convo yesterday where someone claimed that L1 TLBs were teeny tiny (single-digits) so I had to look it up. According to , SKL/SKX L1 dTLB is 64 entries, 8-ways, statically shared between hyperthreads, so effectively 32 entries. Never big enough!

    I should note that the P52 only "throttles" during turbo (which is to say: it doesn't actually throttle badly at all). It has no problem maintaining base clocks while silent, which is pretty great.

    Anyway, I wish they had a 3:2 display option and a centered, 7-row keyboard and all sorts of ponies, but I definitely feel good about getting many good years out of this. P52 thumbs up!

    I got the 1080p display, which is fine. Supposedly P51 1080p was abysmal. I was willing to chance it on the P52, because mixed DPI is not really ready. Mixing 4K on the AW17 and my monitor was not a good experience. I ended up running at 1080p anyway.

    Fortunately, I kept the original windows partition around so I could boot back into the spindle, activate there (maybe it came activated...?), and hope for the best. It worked, although the activation process is so opaque that I'm not even sure if that's what did it.

    The first thing I did was reimage the spindle drive on the the NVMe (Samsung 970 EVO) since ain't nobody got time for rotational latency. But, I almost got locked out of activation. Turns out you should activate and use a MS online account before you migrate!

    The machine feels very well built, and the internals are very easy to access, clearly made to be upgraded and serviced. The first thing I did was add an NVMe drive, since the upcharge on NVMe is way too high. I almost got into trouble because of this!

    Non-centered keyboard. Well, this is a little annoying, especially since apparently they shrank the keys since the P51, but the keyfeel is excellent. Trackpad is fine with discrete buttons. I love the Trackpoint, though, which goes a long way to forgive these ills.

    I haven't done much testing of the Quadro 3200 Max-Q, but it is an interesting part. It does about as well in 3DMark Time Spy as a 1060, but the configuration is pretty different. More cores (still less than a 1070) and less bandwidth (192-bit like the 1060 but lower clocks).

    Fortunately, incremental build/link is relatively bursty, so I do get some benefit from the higher turbo clocks of the 8850. Undervolting -0.1V helps so that it stop power thottling and delays the onset of thermal throttling. YMMV of course,

    I got the P52 when customization became available. To get the best GPU, Quadro 3200 Max-Q, you also need to get the 8850H CPU. It doesn't come with the 8750H or the Xeon. So the question is: will it throttle? Answer: of course.
