AMD Fusion Z-series promises ultimate HD tablets

Written by Nermin Hajdarbegovic


Desna APUs to take on Intel’s Oak Trail
AMD plans to expand its Fusion family with a new series of APUs designed specifically for the rapidly growing tablet market.

Codenamed Desna, the new APUs will be part of AMD’s Fusion Z-series, but at this point technical details are rather sketchy. AMD touts the new series as capable of “powering the ultimate HD tablet” and offering “true APU technology,” which is about as vague as it gets.

However, it is clear that we are looking at proper Fusion parts tweaked for tablets. Bear in mind that AMD’s C-50 APU has already found its way into Acer’s Iconia W500 tablet and it is safe to assume that new Z-series parts will offer slightly superior power efficiency than current C-series APUs. The C-50 variant used in the Iconia reportedly consumes up to 5 watts. However, Z-series specs remains unclear at this point, although it seems likely these APUs will be based on the same Bobcat core as Ontario and Zacate chips.

Of course, Z-series APUs will offer full DirectX 11 compatibility and AMD doesn’t fail to mention that they will be more than capable of smoothly streaming full HD video. In addition, AMD promises acceleration in IE9, HTML5, MS Office 10 and Adobe Flash 10.2. External monitors will also be supported and AMD notes that the Z-series should allow “immersive gaming.”

This promises to be a rather eventful summer for AMD and we will try to find out more about the Z-series over the coming days, so stay tuned.

Let the competitions begin! :-) ;-)

TDP, TDP and TDP.

AMD Fusion-Z - 5 Watts
Intel Oak Trail - 3 Watts

ARM dual core Cortex-A9 - 0.7-0.8 Watts. >95% of whole market of tablets and smartphones.

The all-day battery is possible only with TDP less than 1 Watt.

We still don't know the TDP, but the "old" C-50 tablet version is rated at 5W. I thinks the regular one used in netbooks has a 10W TDP.

No point in making a tablet variant unless it will do better than the one used in the Iconia, so the TDP should probably come close Oak Trail's 3W.

But you're right - even 3W sounds like way too much compared to ARM chips...

AMD Z processor has a powerful GPU with
it.
The videos that Z-series can play, will play like Powerpoint slides on Cortex A9.

Cortex A9 doesn't have a GPU so it's not a right comparison... A9 is a CPU only around which a GPU gets worked in, either Tegra or PowerVR and none of them are as good as Z's. This puts an OMAP4 dual core A9 + PowerVR SGX540 at around 3W TDP. If you compare that with a Z, you can pick between longer leave-me-alone time or better processing power.

It's not a right comparison also when you compare the TDP of an APU with a miniature CPU.

I understand that they both have their uses. You can't fit Z in a smartphone. On the other side, the Z is a better option when you have enough battery.

Clarification:
ARM dual core Cortex-A9 + GPU PowerVR : 0.7-0.8 W.

The efficiency of ARM architecture is 4x-5x higher than of x86 at ultra low TDP.

It means the equivalent performance for CPU+GPU:
ARM Cortex-A9 (2x1GHz) + GPU (total TDP 0.7-0.8 Watts) has the same performance as Intel 3 Watts.

Nvidia Tegra 3: ARM quad-core Cortex-A9 (4x1.5 GHz). Only CPU part will have 3 Watts. It means that Intel will have at least 12 Watts for the same performance. And AMD a bit higher than that.

But Cortex-A9 won't go higher than 3 Watts. That is where AMD and Intel beats ARM (TDP > 12 Watts).

I have looked for little while on the internet I can't find any data about TDP and the Tegra line, could you provide links backing up these claims? I have seen a lot of conjecture and speculation but no hard numbers.

Both Intel and AMD publish TDP which is generally suggests max power. Under average usage model... actual avg. power consumption is about 20-25% of TDP. Thus oaktrail with 3.8W TDP (inclding chipset) would burn avg. power of 1Watt.

ARM folks whether it is Nvidia or qualcomm...nobody publish actual TDP. ARM guys generally talk in terms of avg. power. Generally A9 SOC burn about 0.8-1Watt of average power.

so there is this huge misconception that ARM is more power efficient as people have been comparing TDP for x86 vs Avg. power for ARM.

This ARM energy efficiency lie is about to end. The moment x86 guys bring out single chip SOC ....there will be little ARM advantage and x86 has significantly higher performance for given watts.

@Twist3d1080, I got my value from a Phytec published embedded board with OMAP4 1GHz, the TDP is set to 3W max for all that it does, but also contains an USB host chip and a DRAM chip. If a power usage testing was done, I can't tell. They might just be summing up of all chips' TDP's as it is in each chips' sepcs, which isn't a good method, but still it shows that a general system would not be in the below 1W range.
