Asus P4B533-E and Intel D845GBV in the test: i845E against i845G, i850E and i845D

Vorwo rt

After Intel had already presented the i850E chipset for the new Pentium4 generation with 533MHz Quad Pumped Bus and Rambus on May 6, 2002, further DDR- RAM chipsets. On the one hand, there is the i845E, which is the direct successor to the i845D, and on the other hand the i845G, which provides integrated graphics.

We took a closer look at both chipsets in this review and competed against the i850E and an overclocked i845D.

Above all, we would like to clarify how big the performance advantage of Rambus Systems in the new Pentium4 generation fails before the DDR RAM variants and what Intel's new integrated graphics solution is able to achieve.

For the new i845E chipset, we were able to use the Asus P4B533- E received and thus subjected it to a detailed test. The i845G is represented by Intel's D845GBV reference board. With the i845DThe P4B266-E from Asus, which we had already tested, was used again and the i850E was replaced by the D850EMV2 from Intel.

At this point, we would like to thank both Asus and Intel for providing the in this test use boards and processors.

In contrast to the i850 and i850E, the differences between the i845D and i845E are a bit bigger. This is primarily not due to the northbridge used, but rather to the new southbridge, the ICH4, which Intel uses in both the i845E and the i845G.

In addition to the mandatory support of the new Pentium4 generation with an FSB of 133MHz, the new chipsets in combination with the ICH4 now also offer up to six USB 2.0 ports.

The i845G also has integrated graphics. The graphics core is clocked at 200MHz and uses the working memory of the PC. The 'Intelligent Memory Manager Technology' is supposed to achieve an optimal balance of RAM usage between the integrated graphics and the rest of the system. Up to 48MB of the main memory can be assigned to the integrated graphics via BIOS, as if it were onboard with a graphics card. Intel called its latest integrated graphics solution without further ado 'Intel Extreme Graphics'.

In the following we would like to compare the graphics features of the i845G with Intel's last integrated solution, the i815E:

From the table you can see very clearly that the integrated graphics of the i845G is very much superior to the solution of the i815E, but the current high-end graphics cards are also available not even remotely approach them, of course. The lack of hardware T&L alone would be unthinkable with high-end cards.

But an integrated one has this requirement Graphics also not at all. Intel's goal is to be faster than a GeForce2 MX200. In view of the name 'GeForce2' this seems a bit high, but the 64-bit fast connection of the RAM of a GeForce2 MX200 slows the card down so much that it even falls behind a GeForce1 SDR.

The integrated graphics solution of the i845G is of course more aimed at the OEM PC, which is not used for gaming but for daily office work.

We will find out whether it fulfills this purpose and, for example, is perfect for a second PC Clarify the further course of the review.
