  • No idea why you’re getting downvoted. HDMI 2.1 supports 10-bit 4k 144hz with no stream compression. So the answer, unequivocally, is that yes it can.

    DisplayPort 1.4 requires DSC (stream compression) to do the same. DisplayPort 2.0/2.1 supports higher bandwidth but it is not common on displays at this point in time.

    People have other understandable reasons for preferring DisplayPort over HDMI (Open vs. closed standards), but there is no disputing the fact that HDMI currently outclasses DisplayPort in terms of bandwidth and thus the limits of what kind of signals it can carry.










  • Ok so I am about to build a new rig, and looking at the specs the X3D does seem less powerful and more expensive than the regular 7950.

    While I completely agree that this guy seems extremely biased and that he comes off like an absolute dickbag, I don’t think the essence of his take is too far off base if you strip off the layers of spite.

    Really, it seems like the tangible benefit of the X3D that most people will realize is that it offers similar performance with lower energy consumption, and thus lower cooling requirements. Benchmarks from various sources seem to bear this out as well.

    It seems like a chip that in general performs on par with the 7950x but with better efficiency, and if you have a specific workload that can benefit from the extra cache it might show a significant improvement. Higher end processors these days already have a fuckton of cache so it isn’t surprising to me that this doesn’t benchmark much better than the cheaper 7950x.



  • You would want to look for an R730, which can be had for not too much more. The 20 series was the “end of an era” and the 30 series was the beginning of the next era. Most importantly for this application, R30s use DDR4 whereas R20s use DDR3.

    RAM speed matters a lot for ML applications and DDR4 is about 2x as fast as DDR3 in all relevant measurements.

    If you’re going to offload any part of these models to CPU, which you 99.99% will have to do for a model of this size with this class of hardware, skip the 20s and go to the 30s.



  • The Ford Mach-E is excellent. I have also heard great things about Kia/Hyundai, VW and Volvo EVs as well.

    In 2016 I drove a Tesla Model S P85D and I was surprised at how crappy the interior was considering it was a six figure car. And I don’t mean minimalist, I mean poor quality.

    Back then, Tesla was you only real option. Today, there’s a lot of great competition in the market.
