NVIDIA gives up a few more mouth watering details on mobile HD platform

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.

10 hours?

I expect a mobile device to last a full 18 hour day. There is nothing more annoying than your phone, PDA, GPS, MP3, or whatever the device is dying.

I want to be able to use these features and enjoy them, not worrying about if it will last me through the day.

Presumably for a mobile device like a phone, it is in deep sleep most of the time, hence the battery life will be longer, and an MP3 player doesn't need to run the device at its full speed. I presume that the 50mW is the typical power consumption though.

50mW for CPU, GPU and chipset. That's at least 1/20th of Atom+Paulsbo, and a fraction of the size.

GPS units using this will get some excellent graphical interfaces. Can't wait to see some early units.

Faster than the CPU in the iPhone too, I expect.

Who in the world talks on their phone for 18 hours straight. Obviously it would have a low-power/sleep profile
