An evaluation of the Sophon SG2044 — mentioned by inkyotohttps://news.ycombinator.com/item?id=48904924urn:hackerpapers:mention:2508.13840:48904924Tue, 14 Jul 2026 11:07:51 GMT<p>Performance gap is not closing in specimens commercially available today, and the promises of it «happening any moment from now» are now indistinguishable from monthly horoscopes. For example, Zen 2 is a 2019 design, and the 64-core SG2044 C920v2, which was released in May 2025, a three-decode, four-dispatch core at about 2.6 GHz, with 128-bit vectors is still approximately[0]: – 9 times slower in the block tridiagonal solver at 64 cores; – 2.05 times slower in the lower-upper Gauss-Seidel solver; – 2.05 times slower in the scalar pentadiagonal solver. Given a six year gap between two design…</p><p><a href="https://hackerpaper.kaipfister.de/p/2508.13840/">Paper and discussion history</a>. A mention is not an endorsement.</p>cs.DC
