Jitter and OpenGL on a Macbook (_NOT_ a macbook pro)

Jun 04 2006 | 10:37 pm

has anyone played around with Jitter (specifically stuff) on a
macbook? the lack of a dedicated graphics card makes me nervous. i’d
love to hear anyone’s expirience wrt performance.

Well, i don’t have a macbook nor a macbook pro… but from some
googling, here is theoretically what can be deduced:

The macbook features an Intel GMA 950 graphics processor chipset,
which means:
– it uses system memory for graphics;
– some of the 3D is done by the main processor, i.e. software rendering…
The GMA 950 is a graphics business chipset.

Check benchmarks of 2 recent PC laptops, a HP DV1000T and a Fujitsu
LifeBook N6410, with similar chipsets as macbook and macbook pro, so
one (HP) featuring the G450 chip and another one (Fujistsu) with an
ATI mobility X1400 (the macbook pro has an ATI Mobility Radeon
see on: aptop_features_new_intel_gma_950_graphics_processor/page10.h tml

So results are near 4 times faster on the Fujistsu laptop using an
ATI; although this is on Windows, i think we should not see very
different results on Mac OSX.
