You need to purchase the $10,000 cable and connect it to the most affordable Realtek NIC available for top-tier performance. In practice, results often depend more on chipset quality, driver support, and switch characteristics than on noticeable differences. While a cheaper Realtek may offer marginal gains over an Intel, the real impact usually comes from USB overheads rather than the hardware itself. Despite this, Realtek has improved recently with their 2.5Gbit USB-C NIC, delivering solid performance. Although it shows a slight ping advantage (0.26ms vs 0.19ms), it’s likely due to USB-related factors. In my experience, I’ve faced no issues connecting Gigabit Ethernet cables from eBay, even over long distances, as long as the connectors are properly matched.
