More details on AMD’s Brazos platform, which is part of their upcoming Fusion / APU range due out early next year, has been revealed over the weekend to several tech sites which includes some hands on experiences and a product lineup. Just to refresh your memory the Brazos platform includes two APUs, or Fusion processors (combination of CPU and GPU) based on the “Bobcat” core – Ontario and Zacate. The former is intended to tackle the netbook segment and the latter, thin and light notebooks, both intended to cover devices under $.
Here’s the Brazos platform product line up, both APUs include single and dual core models.
|APU||Model||Bobcat Cores||CPU Speed||GPU||Shaders||GPU Speed||TDP|
|Zacate||AMD E-350||2||1.6 GHz||Radeon HD 6310||80||500 MHz||18 W|
|AMD E-240||1||1.5 GHz||Radeon HD 6310||80||500 MHz||18 W|
|Ontario||AMD C-50||2||1.0 GHz||Radeon HD 6250||80||280 MHz||W|
|AMD C-30||1||1.2 GHz||Radeon HD 6250||80||280 MHz||9 W|
First two Zacates are aimed at nettops and thin and lights with a $399 – $449 price range. The last two for netbooks with netbook pricing, I suppose.
Some notes (technical specs mostly not new):
- DirectX 11 support
- 8.5 – 9 hour “battery life” for Zacate laptops with 55 Wh batteries. (for reference AMD Nile quoted at 8 hours with 61Wh battery but delivers just under 5 hours real life usage)
- 10.5 hours “battery life” for Ontario laptops / netbooks.
- Single core models are actually dual core but have one core disabled. Core unlocking is “apparently possible but unexpected”.
- Memory – two DIMMs (RAM slots) are supported on a single 64-bit channel memory controller with speeds maxing out at DDR3-1066.
- Up to 50% graphics performance improvement over Nile platform.
- Video – dual displays concurrently with VGA / HDMI / Display Port / DVI or LVDS.
- Temperature – 90 F / 32 C under full load, with active cooling
- H.264 / VC1 / DivX / Xvid playback support with UVD3.
- I/O – up to 14 x USB 2.0 ports, 6 x SATA 6Gbps and 4 x PCI-e lanes.
Hands on – overall positive responses but not much revealed yet. The top end Zacate APU (E-350) was given out to test and power consumption never spiked above 20 W. High bit-rate 720p played well. Windows 7 felt responsive even while running some benchmarks. Most streaming HD services worked without issue. It didn’t “stray too far” from a current AMD Nile processor and a dual core Celeron SU2300 processor in terms of CPU performance.
Gaming – Crysis at 720p resolution was “enjoyable” at low settings. Apparently the 50% improvement in graphics isn’t just a best-case scenario.
More hands on experiences will be revealed next week.
