AMD says a sub-9W G series SoC is weeks away

Pushing Jaguar to the power limit

CHIP DESIGNER AMD said it will announce a sub 9W G series system on chip (SoC) in the coming weeks to show how low it can take the Jaguar architecture.

AMD's latest G series chips are the firm's first true SoC parts, integrating its latest Jaguar CPU architecture with a GPU based on its Sea Islands architecture and including an I/O controller on the same die, all for a 9W thermal design power (TDP) rating. Now the firm has told The INQUIRER that it will announce a sub-9W TDP G series SoC in the coming weeks.

AMD's five Jaguar based G series processors range from a dual-core 9W TDP part up to a quad-core 25W TDP part boasting a GPU that supports OpenGL, OpenCL and Microsoft's DirectX 11.1. However Kamal Khouri, director of Embedded Products at AMD told The INQUIRER that AMD can push its architecture into lower power processors.

Khouri said, "We will have SKUs that are 9W all the way up to 25W, which is super fast. We also do have plans to introduce a less than 9W part, we're not announcing it on Tuesday [AMD G-series launch day] but it is in the works and within the month we will announce the part.

"We are pushing the bounds on how low we can get in terms of power that our customers have truly fanless and cheap cooling and thermal solutions."

Khouri continued by saying that AMD managed to hit its TDP figures without powering down parts of the chip. He said, "It's not by shutting off major chunks of IP [that AMD hits its TDP figures]. So the 9W part has the GPU, has the cores, it is tweaking the frequency and the other settings to get to that point."

According to Khouri, the firm has seen the most interest in its low-power G series chips, specifically the dual-core 9W part. If the firm can push its G series SoCs further down the scale into single-digit TDP values, it bodes well for the firm's upcoming tablet and server focused chips and might give Intel something to think about, especially given AMD's GPU strength. µ
