Yes, Hollywood is a multi-chip module, with two chips: Napa and Vegas:
Napa includes the GPU, a 3MiB cache (framebuffer and textures), an IO controler, and a memory controler.
Vegas holds the Audio DSP, and the 24MiB of 1T-SRAM internal to the graphics chip.
Now, it is of important to note two things:
The DSP is not part of the die sizes I gave for the Hollywood's Napa, but probably is for the Flipper.
The 3MiB of cache did not change between Flipper and Hollywood. Note that this was suspected to take about a third of the Flipper's die size.
These two things combined mean that the space that is actually used for logic inside the GPU is likelly to have more than tripled really. And that equates to new features. What new features? No one really knows for sure.
