    1. Coming back to the two ‘FreeSync’ settings in the monitor OSD, they differ in the variable refresh rate range that they support. ‘Standard Engine’ supports 90 – 144Hz (90 – 119Hz via HDMI) whilst ‘Ultimate Engine’ gives a broader variable refresh rate range of 70 – 144Hz (62 – 119Hz via HDMI). We didn’t notice any adverse effects when using ‘Ultimate Engine’, so we’d suggest users simply stick to that option.

      In my tests using Standard Engine, in combo with G-Sync Compatible Driver, I get more screen flickering during menus.

    1. Chipmakers Nvidia, AMD Ride Cryptocurrency Wave — for Now

      Shares of Nvidia Corp. and Advanced Micro Devices Inc. have gained at least 14 percent since the beginning of June, spurred in part by about a 10-fold boom from April to June in a market, known as ethereum, for a currency that can be used to buy computing power over the internet.

    1. evolution from PCI 1.0 through PCI-Express 5.0

      While the evolution of PCIe speed is definitely of interest, especially as it keeps pace with network speeds, the total number of PCIe lanes also a significant barrier to I/O for many systems... Especially in HPDA.

      We can effectively double network throughput by dropping in another 16x NIC. This becomes less possible if there are not enough slots (or perhaps more importantly if available PCIe lanes are oversubscribed). This becomes even more of an issue, as the author points out, with the advent of NVMe.

      Intel has a vested interest in keeping the number of PCIe lanes at 40 with Xeon and holding back implementation of PCIe 4.0. They provide proprietary high speed I/O to their Xeon Phi coprocessor and Optane memory products. This doesn't allow GPUs, FPGAs and competing NV memory products to compete on equal footing.

      AMD is somewhat breaking the stalemate with Zen Naples offering 128 PCIe 3.0 lanes. Will have to see if OEMs build systems that expose all of that I/O.
