Asus P4G8X Deluxe with E7205 in the test: Dual-Channel DDR-SDRAM for Pentium 4

Foreword

The fan base of the Pentium 4 have to wait for dual-channel DDR-SDRAM for the beloved processor and now it is once again the processor manufacturer himself who is the first to come onto the market with a corresponding chipset. The E7205 (Granite Bay) was actually only intended by Intel for use in workstations, but since it can also be placed very well in the desktop segment, many mainboard manufacturers have decided to offer such boards for normal end customers. However, there is one small catch: The price of the E7205 and thus also the corresponding boards is slightly higher than the other desktop chipsets. But we will go into this in more detail in the further course of the review.

Most interesting should certainly be howthe E7205 (Granite Bay), which has dual-channel DDR266 and finally achieves an optimal bandwidth of 4.2 GByte/s for the Pentium4 with DDR-SDRAM, compared to the PC1066 Rambus, which also beats 4.2 GByte/s can transfer.

This is exactly what we want to clarify in our new review and leave the P4G8X from Asus in our new test system against the P4T533 with PC4200 Rambus and the P4PE from Asus compete with Intel's i845PE and DDR333. Who will leave the field as the winner?

The innovations of the E7205 (Granite Bay) are quickly mentioned. AGP8x and dual-channel DDR-SDRAM were donated to it and since it is used in conjunction with the ICH4, the innovations are therefore limited. Dual-channel DDR-SDRAM support certainly makes sense and could at least theoretically bring it the performance crown. But can Intel really be softened and bring a chipset that only leaves the Pentium4's workhorse - Rambus - in second place? The tests will show it and that's why we want to take big steps forward and no longer deal with the theory.
