Back in February, DailyTech brought news of NVIDIA's
upcoming mobile video and graphics processor, not for laptops but for smaller,
hand-held devices such as mobile phones, PDAs, etc. The APX
2500 HD video and graphics processing platform looked interesting on paper
and looked even better in screen shots and demo videos with clean 3D rendering
and silky smooth interface animations.
A recent product briefing with NVIDIA revealed a few more tidbits regarding the
APX 2500 mobile processing platform including a power consumption of 50 mW
which allows the chip to run up to 10 hours with a single battery charge. This
makes the APX 2500 an ideal solution for mobile phones, PDAs, and GPS devices.
In fact, NVIDIA states that the first devices to implement the APX 2500
processor will be GPS devices as early as this year. Implementation of the APX 2500
in mobile phones will soon follow.
According to NVIDIA, the APX 2500 is a single chip solution which has a package
slightly smaller than a dime. The chip will include an ARM11 MP core with a maximum clock speed of 750MHz, a GeForce class GPU, a
high-definition audio and video processor, memory, and IO system and an image
signal processor all in the same package. Though the chip is no larger than a
dime, NVIDIA states the APX 2500 is capable of running high-definition video
flawlessly through HDMI 1.2 with additional dual display capabilities to view video
on both the device and a high-definition display.
The APX 2500 is stated to deliver high-definition video up to 720p resolution
in H.264, MPEG-4, and VC-1 formats. The GeForce GPU is capable of producing 3D
graphics with features such as programmable pixel shaders and vertex &
lighting, as well as coverage sampled anti-aliasing.
With such a low power requirement and a small form factor, many are skeptical
of the APX 2500's performance, however, demos have already shown what the chip
can do as far as 3D rendering and with a little creativity, product makers
should be able to implement all of the goodies
into future products utilizing this mobile processing platform.
