AnandTech hat in einem Kurztest einen Opteron 250 und einen auf 2,4 GHz heruntergetakteten Opteron 252 mit dem neuen E4 Stepping auf einer HP wx9300 Workstation gegeneinander antreten lassen und dabei versucht die Vorteile des nun unterstützten SSE3 Instruktion Sets zu ergründen.
"Finding good SSE3 benchmarks wasn't as easy as we would have liked. Other encoding suites react the same way that DivX and AutoGK do. This seems to indicate that the K8 architecture is simply resilient when it comes to unaligned 128bit loads. In the case of Intel's NetBurst, the lddqu instruction may have more impact.
As far as physics and graphics go, the added instructions show potential in our synthetic test. For DCC, CAD, scientific, and other workstation software, the E4 stepping could offer a bit of a performance boos"
