Not quite.
The 4110 has 64MB TRAM and 64MB Z buffer along with 16MB directburst for rasterization. It's capable of processing roughly 7.5 million polygons per second.
The 4210 is the strongest offering as it has double that in all categories and processes just over 15 million polygons per second and is also HDTV compatible as it is the card used in Intergraph's HDAR system (High Definition Animation Recorder) and is also used in systems for many other high performance editing applications such as Softimage|DS (now Avid|DS).
The 5110 is a replacement for the 4110 and is optimized for the P4 architecture. Both the 4110 and 4210 are designed for the P3 architecture. The 4210 processes information faster than the P3 can supply it as well.
Despite the stats, the 4210 is the charlie hustle of the bunch, but the 5110 will give you the most bang for the buck as it costs half as much.
If you're looking to build a P4 system, then 5110 is your choice. The 4110 and 4210 cost more if purchased new as well.
