The overall trend in processor design has been to integrate more gmcu onto fewer components, which decreases overall motherboard cost and improves performance. Both versions of the GMCH are pin-compatible, hence one manufacturer can have a low cost model and the premium model without the need to redesign the base model.

GMCH – Intel Chipset
A northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboardthe other being the southbridge. The system memory bus is arbitrated between texture MIP-map accesses and rendering functions.
For example, if 2 MB of system memory is needed, the driver allocates this amount.
Retrieved ggmch ” https: There are a few chipsets that support two types of RAM generally these are available when there is a shift to a new standard. In that situation, the GMCH’s integrated graphics becomes more favorable because of it’s higher bandwidth to the system’s memory.
It was supposed to be a server chipset ;p Reply. Log in Don’t have an account? Unsourced material may be challenged and removed.

The northbridge would then be connected to the rest of the chipset via a slow bridge the southbridge located south of other system devices as drawn. One thing people forget is the venerable BX was actually the hi-end server chipset – it wasn’t intended to be the bread and butter Slot 1 mainstream chipset. This rendering model requires 4 MB of display cache and allows graphics rendering performed across the graphics display cache bus and texture MIP map access performed across the system memory bus simultaneously.

As you may be able to guess, there are two parts to the i GMCH, the graphics and bmch memory controllers, although they are both packaged together. On a different note, we would like to reiterate that the integrated RAMDAC rated at a lowly MHz, but fortunately in our use, it managed a sharp output up to x 75Hz.
From Wikipedia, the free encyclopedia. Don’t get excited yet dhipset all the graphics adapters have their own local memory that has far higher bandwidth between the graphics chipset and the onboard memory, but once the graphics data usually texture data gets too large for the local memory, they’ll have to spillover to the system memory if the graphics adapter uses an AGP connection.
The name is derived from drawing the architecture in the fashion of a map.
One of the advantages of having the memory controller integrated on the CPU die is to reduce latency from the CPU to memory. Overall the idea of dedicated cahce and the Direct-AGP connection is far better than the old UMA-architecture in older motherboard designs. This page was last edited on 8 Octoberat In addition to D. This also means any standard PC memory will do the job without you needing gmcg hunt for those speedier and more expensive RAM.
If later, chipseet 1. There is a way, says system-level security gmh. The DC descriptor just means that it uses MHz cache. Separating the different functions into the CPU, northbridge, and southbridge chips was due to the difficulty of integrating all components onto a single chip.
This means even if you intend to overclock the system by changing the FSB, the memory bus can still operate at MHz.
