First Look At Brookdale - Intel's Upcoming 845 Chipset

Sandra Memory Performance (STREAM)

This benchmark shows that the memory performance of i845 with PC133 SDRAM is about 50% of i850 with PC800 RDRAM. However, it is surprising to see that i845 doesn't score much worse than Athlon with AMD760 and PC2100 DDR-SDRAM in this test.

Although Pentium 4 1.7 GHz with i845 is losing 20% versus i850, it still remains well ahead of Athlon 1400. This is obviously due to the hand-coded SSE2 implementations. It shows however, that memory bendwidth isn't the whole secret behind those benchmark scores.
