    OK great, so we can do some number crunching. Working off of boost clocks to produce rough relative performance metrics between the cards...
    (Boost clock numbers for the GeForce cards comes from TechPowerUp GPUDB)

    Quadro T1000 (mobile) = 768 cores @ 1.69 GHz = 40%
    Quadro T2000 (mobile) = 1024 cores @ 1.71 GHz = 54%
    Quadro RTX 3000 (mobile) = 2304 cores @ 1.39 GHz = 99%
    GeForce RTX 2060 (desktop) = 1920 cores @ 1.68 GHz = 100% (baseline)
    GeForce RTX 2070 (desktop) = 2304 cores @ 1.62 GHz = 116%
    Quadro RTX 4000 (mobile) = 2560 cores @ 1.56 GHz = 124%
    Quadro RTX 5000 (mobile) = 3072 cores @ 1.53 GHz = 146%
    GeForce RTX 2080 (desktop) = 2944 cores @ 1.71 GHz = 156%

    This is of course assuming that boost clocks can be maintained in the mobile Quadros. (And, I think that the desktop cards nowadays will go even higher than the boost clock if there is thermal headroom?) I have a hard time believing that Quadro RTX 5000 can run at 1.53 GHz, consuming 110W of power, when the GeForce RTX 2080 has 215W TDP.

    (I previously speculated that the RTX 3000 would perform in line with a GeForce 2060 --- which looks about right judging by the numbers --- and that the RTX 5000 would perform in line with the GeForce 2070. I didn't realize that the "difference" between the GeForce 2060 and 2070 is so small, compared to 1060 vs 1070. There could be something like the memory bandwidth that further differentiates them which I did not take into account.)

    firest and Ionising_Radiation like this.

    Ionising_Radiation ?v = ve*ln(m0/m1)

    It's prudent to note that the power curve is quadratic, so that might just mean that NVIDIA has chosen the most efficient point on the curve to clock their GPUs. Obviously I am picking at straws here, since we don't really have complete details yet.

    Good breakdown, though—I think your analysis will be a good ballpark for the actual performance of these cards. Still worth upgrading, though, because the RTX 3000 is going to be twice as fast as the P3200.

    As for RTX 2060 vs 2070, once again I fall back on the 3DMark Fire Strike benchmark—the 2060 is once again, as fast as the 1080, similar to how the 1060 was as fast as the 980. Pretty decent performance jump. If the RTX 3000 appears to go a little higher, then perhaps we can expect RTX 2070 Max-Q performance.

    Talked to Dell sales because I wanted to know why MBP is already available with 8 core i9 but the 3541 isn‘t. After he gave me his mail, I asked for a quote on my desired 7740 which he responded to saying it would become available in 2 weeks and he‘ll send me a quote then

    Past experience from me and many others has demonstrated that the sales reps don't know any more than the general public about when exactly a system will be released, and tend to "guess" and maybe even string you along a bit to keep you from going over to the competition. Dell's press release pins the release for "early July" and these are typically reliable, so I think that is what you should plan for. A sales rep won't be able to give you a quote before orders also go live online. Also, the systems take at least two weeks to ship out after orders go live at launch, I doubt anyone will be actually seeing one until towards the end of July.

    Regarding why the CPU is available in the Mac and not in the Precision, Dell is following their usual schedule for the Precision line — it usually shows up towards the end of the refresh cycle, two or three months after the mobile CPUs first become available, with other systems like Alienware/Inspiron/XPS/Latitude coming first. (Apple was uncharacteristically on the ball this time around.)

    I heard that hp is using the same chassis for its zbook 17 g6 which means a rtx quadro 5000 mxm gpu module is more than likely. This mxm could POSSIBLY be used in other laptops like clevo's etc. So old laptops like the p870dm-g could continue going. Of course the downside would be the insane price for the mxm card lol and no one knows yet either...

    The 60/70 range SKUs oscillate between sharing chips or using different chips. Since it's not really feasible to bin a chip too far down, sometimes, there isn't as great a gap between the 60 and 70 range SKUs.

    HP likes to do strange things with the vBIOS on their MXM cards (or, not have a vBIOS on the card at all, leaving it on the motherboard). I wonder if anyone got the Quadro P5200 from HP working in another system?

    It works in msi and clevo, some guy or baidu made it work fine.

    ... soldering a BIOS chip as far as I know.
