Advanced Micro Devices plans to refresh the lineup of its E-series inexpensive accelerated processing units (APUs) for desktops in the third quarter of this calendar year. Performance boost will hardly be tangible and will include a slight increase in clock-speed and addition of AMD Turbo Core dynamic acceleration technology.

In Q3 2011 the company will launch E-450 and E-300 code-named Zacate accelerated processing units with two Bobcat cores, 80 stream processors, video decoding engine, 18W thermal design power (TDP) and so on, X-bit labs has learnt. The dual-core E-300 APU will substitute single-core E-240 chip, whereas the dual-core E450 will complement the existing E-350 with higher performance amid similar power consumption and FT1 form-factor.

The clock-speeds of the second breed of E-series desktop APUs will remain low - in the range between 1.30GHz and 1.65GHz - but thanks to Turbo Core dynamic acceleration technology the new chips promise to offer noticeable speed improvement compared to the first models of Zacate APUs. It remains to be seen whether AMD will also refresh the Ontario APUs for netbooks as well.

In order to address the market of low-end desktops with more or less decent performance, AMD intends to release AMD E2-3250 APU that will be based on a low-end Llano design with two Husky CPU cores, cut-down Winterpark graphics engine with 160 stream processors, and will thus offer tangibly better performance compared to Zacate, but will have 65W TDP and FM1 packaging.

Nice to see AMD planning a quick update to these APU's. Hopefully the E-450 will finally bring the holy grail of low end gaming, letting WoW and such run at 720p 30fps. The E-240 deserves to die, so hopefully the E-300 will see to that.

I doubt the E2-3250 is a 65W part as it's based on the 32nm fabrication process and even the highest performing mobile Llano APUs with much better integrated graphics are rated at 45W max.

My guess, judging by the DDR3 1600MHz support it would be that the chip has a 45W TDP.

There were numbers of 90W-100W thrown recently for desktop Llano, which makes 65W for the low end part quite reasonable. Mobile Llano will indeed be 45W, but desktop parts always have much higher power draw than mobile ones.

turbo core should be a huge boost. amd introduced ACP a long time ago in part to highlight how rarely TDP thermal levels are ever reached. turbo core exploits this, and should make a huge difference on Zacate.

Suddently, XBits Labs seems to be able to get inside info on upcoming AMD products.

The E2-3250 smells like a desktop version. Probably a dual with 3.5Ghz.
