However, their inexperience in engineering and developing mainboard chipsets showed.

The 9100 IGP is capable of 2:1 data compression along the memory bus, which should definitely help graphics bandwidth loads.Īt first ATI seems to be positioned in a sure win scenario. In an attempt to alleviate this bottleneck, ATI has incorporated memory compression technology into the chipset. You can see how this will impact performance throughput. Comparatively, the dual channel DDR-400 controller of the 9100 IGP has a peak bandwidth of only 6.4GB/s. Memory bandwidth in today's graphics accelerators exceed 30GB/s. They have to share onboard RAM, relatively many times slower than dedicated memory available to standalone graphics cards. The Intel 865G's Extreme Graphics 2 core however, was a DirectX 7 part with no pixel shader or FSAA support and it wasn't able to live up to its 'Extreme' moniker in real world performance.Īn inherent weakness with integrated graphics chipsets is the use of system resources. It also boasted TV-Out support and a feature called SURROUNDVIEW, which enables support for three monitors by combining an external AGP card with the IGP.

It was the first P4 chipset to have hardware pixel shader 1.4 and DirectX 8.1 support and was capable of 4x FSAA (Full Screen Anti-Aliasing) and 16x AF (Anisotropic Filtering). The 9100 IGP boasted a built-in RADEON 9200 VPU with an impressive feature list. Thus, the RADEON 9100 IGP was introduced as the direct competitor to the Intel 865G for Pentium 4 and Celeron processors on socket 478.

ATI was banking on the success of their RADEON series of VPUs to make an inroad. In terms of integrated graphics for the Intel platform, the only passable chip at the time was Intel's own 865G. When both companies decided to begin developing IGP chipsets, many could foresee new levels set in integrated graphics which has so far been marred by severely crippled performance. Both companies have established themselves as the key players in the consumer 3D graphics processor market. However, one cannot but compare ATI with NVIDIA in this situation too. Instead of competing with their archrival NVIDIA in the AMD camp, ATI is exploring the Intel route. Codenamed RS300, the RADEON 9100 IGP was aimed to bring performance to the value market. In June 2003, ATI launched their long awaited Pentium 4 chipset, the RADEON 9100 IGP.
