Tegra 250 sets mobile speed record
- second-generation Tegra processor has been sampling since 3Q09 and is expected to reach production in 2Q10
- contains two Cortex-A9 CPUs, each running at up to 1.0GHz.
- should score 5760 on the Coremark test (using two threads)
- more than twice the speed of the iPhone 3GS, Nexus One, or any other smartphone shipping today
- 40% faster than the Coremark score of the 1.6GHz Atom CPU (also using two threads with hyperthreading).
- exceeds 1.0W at full speed from both cores
- 150mW for HD (720p) video playback and just 15mW for audio playback –> similar to original Tegra
- can decode video at 30fps and full HD (1080p) resolution for H.264 base and main profile
- restricted to 720p for the ultrachallenging H.264 high profile (Blu-ray)
- can also encode video at 1080p for H.264 base profile.
- Few other mobile processors can handle 1080p video at even the base profile.
- 3D performance : peak speed of 90 million triangles per second.
- will appear initially in tablet computers and similar-sized devices that will debut by mid-2010.
- smartphones will not ship until late 2010
- third-generation processor expects to sample before the end of this year
