Intel Pentium D 820 - Page 3

..:: SiSoftware SANDRA ::..

First off, let’s examine the results obtained from SANDRA for Arithmetic ALU & FPU performance. As we can see from the results above, the Extreme Edition 840 with two cores and HT enabled hammer the other Intel solutions. The Pentium D 840 falls back, but still manages to post up the second highest scores we’ve seen to date. This jump down from the Extreme Edition is due to the lack of Hyper-Threading support on the Pentium D. When it comes to Arithmetic FPU performance, we find the same story as was seen in the ALU results.

When it comes to both Integer and Floating Multimedia results, we see a similar story. In these results, we again see the Extreme Edition 840 CPU holding a massive performance lead over the remaining Intel processors, but the Pentium D 820 manages to slide into second score-wise. The other P4 EE’s are seen holding a slight performance lead over the “Prescott 2” based 6xx processors. In turn, the 6xx series hold a minor performance lead over the 5xx series.

Finally, we have the Integer and Floating results obtained from the memory bandwidth benchmark. For memory bandwidth, the Pentium EE 840 is seen bringing up the rear of the pack, while the Pentium D 820 actually manages a better score in-line with the Pentium 4 660. When it comes to the Floating performance results, we see nothing different, with the 3.73GHz EE coming out well on top, as it should, and the Pentium Extreme Edition 840 pulling up the rear.
