In a feat of overclocking prowess, the crew over at Akiba have managed to push the AMD Llano A8-3850 to its limits to achieve a Super PI 32M score of 14 minutes and 17.5 seconds at an impressive 4.75GHz. Using a retail A8-3850 APU, a Gigabyte GA-A75-UD4H motherboard, and a spine chilling amount of Liquid Nitrogen, the Japanese overclocking team came very close to breaking the 5GHz barrier.

Just how close did they come? 4.906.1GHz with a base clock of 169.2MHz to be exact, which is mighty impressive. Unfortunately, the APU had to undergo some sever electroshock therapy at 1.792 Volts! Further, the 4.9GHz clock speed was not stable enough for a valid Super PI 32M result; therefore, the necessity to run the benchmark at 4.75GHz.

The extreme cooling ended up causing issues with the motherboard once the team tried to switch out the A8-3850 for the A6-3650; therefore, they swapped in an Asus F1A75-V PRO motherboard. With the A6-3650, they achieved an overclock of 4.186GHz with a base clock of 161MHz and a voltage of 1.428V. The overclockers stated that they regretted having to swap out the Asus board as they believed the Gigabyte board would have allowed them to overclock the A6-3650 APU higher due to that particular motherboard’s ability to adjust voltage higher.

Although they did not break the 5GHz barrier, they were still able to achieve an impressive 69% overclock on the A8-3850 and a 61% overclock on the A6-3650 APU. For comparison, here are PC Perspective’s not-APU-frying overclocking results. At a default clock speed of 2.9 and 2.6 respectively, the A8-3850 and A6-3650 seem to have a good deal of headroom when it comes to bumping up the CPU performance. If you have a good aftermarket cooler, Llano starts to make a bit more sense as 3.2GHz on air and 3.6GHz on water are within reach.  How do you feel about Llano?

Video Perspective: AMD A-series APU Dual Graphics Technology Performance

Subject: Graphics Cards, Processors | July 13, 2011 - 02:13 PM |
Tagged: llano, dual graphics, crossfire, APU, amd, a8-3850, 3850

Last week we posted a short video about the performance of AMD's Llano core A-series of APUs for gaming and the response was so positive that we have decided to continue on with some other short looks at features and technologies with the processor.  For this video we decided to investigate the advantages and performance of the Dual Graphics technology - the AMD APU's ability to combine the performance of a discrete GPU with the Radeon HD 6550D graphics integrated on the A8-3850 APU.

For this test we set our A8-3850 budget gaming rig to the default clock speeds and settings and used an AMD Radeon HD 6570 1GB as our discrete card of choice.  With a price hovering around $70, the HD 6570 would be a modest purchase for a user that wants to add some graphical performance to their low-cost system but doesn't stretch into the market of the enthusiast.

The test parameters were simple: we knew the GPU on the Radeon HD 6570 was a bit better than that of the A8-3850 APU so we compared performance of the discrete graphics card ALONE to the performance of the system when enabling CrossFire, aka Dual Graphics technology.  The results are pretty impressive:

You may notice that these percentages of scaling are higher than those we found in our first article about Llano on launch day.  The reasoning is that we used the Radeon HD 6670 there and found that while compatible by AMD's directives, the HD 6670 is overpowering the HD 6550D GPU on the APU and the performance delta it provides is smaller by comparison.  

So, just as we said with our APU overclocking video, while adding in a discrete card like the HD 6570 won't turn your PC into a $300 graphics card centered gaming machine it will definitely help performance by worthwhile amounts without anyone feeling like they are wasting the silicon on the A8-3850.

Video Perspective: AMD A-series APU Overclocking and Gaming Performance

Subject: Graphics Cards, Motherboards, Processors | July 6, 2011 - 08:15 PM |
Tagged: amd, llano, APU, a-series, a8, a8-3850, overclocking

We have spent quite a bit of time with AMD's latest processor, the A-series of APUs previously known as Llano, but something we didn't cover in the initial review was how overclocking the A8-3850 APU affected gaming performance for the budget-minded gamer.  Wonder no more!

In this short video we took the A8-3850 and pushed the base clock frequency from 100 MHz to 133 MHz and overclocked the CPU clock rate from 2.9 GHz to 3.6 GHz while also pushing the GPU frequency from 600 MHz up to 798 MHz.  All of the clock rates (including CPU, GPU, memory and north bridge) are based on that base frequency so overclocking on the AMD A-series can be pretty simple provided the motherboard vendors provide the multiplier options to go with it.  We tested a system based on a Gigabyte and an ASRock motherboard both with very good results to say the least.  

We tested 3DMark11, Bad Company 2, Lost Planet 2, Left 4 Dead 2 and Dirt 3 to give us a quick overall view of performance increases.  We ran the games at 1680x1050 resolutions and "Medium"-ish quality settings to find a base frame rate on the APU of about 30 FPS.  Then we applied our overclocked settings to see what gains we got.  Honestly, I was surprised by the results.

While overclocking a Llano-based gaming rig won't make it compete against $200 graphics cards, getting a nice 30% boost in performance for a budget minded gamer is basically a no-brainer if you are any kind of self respecting PC enthusiast.

Llano's physical examination keeps on going on

Subject: Processors | July 6, 2011 - 12:53 PM |
Tagged: llano, APU, amd

Llano is still very active in the news, as reviewers try to pin down exactly what the capabilities of a true APU are; what does it do well and what does it not do well.  Most reviewers have discovered that AMD's offering is relatively weak at current generation general computation and absolutely amazing as an integral GPU.  Part of the weakness in computational tasks seems to stem from the scarcity of programs that can take advantage of multi-core processors and the almost complete lack of GPU accelerated programs ... that are not graphical in nature.  X-bit Labs takes a very in depth look at the modified Stars core called Husky and the Sumo graphical portion which resembles Redwood.

"Desktop Lynx platform that includes hybrid Llano processors has finally found its way to the consumers. Let’s take a closer look at it and find out how successful the combination of old Stars processor cores and a high-performance Radeon GPU actually is."

In one corner is the $140 AMD A8-3850 and in the other is the $135 Intel Core i3-2100T, with matching motherboards both about $100.  We have seen how the new Llano chips stack up in computation and gaming but their use in HTPC systems is also important and requires different benchmarks.  Bjorn3D takes a look at the two chips ability to properly render Blu-ray at the proper 23.976 fps naturally as well as taking advantage of Direct X Video Acceleration.  Take a look to see how AMD's new APU can handle a role as an HTPC.

"In addition to being a capable mainstream APU, the Llano and the new Lynx platform have the potential to be a perfect match for a more capable HTPC system. In this article we are taking a look at the HTPC capabilities of the A3850 and a Gigabyte A75 motherboard, and contrasting it to a comparable Intel system with a Core i3-2100T and an ASRock H67 motherboard."

Meet Hondo, AMD's soon to arrive 2W TDP Brazos chip for tablets ... and Apache servers?

Subject: General Tech | July 5, 2011 - 12:06 PM |
Tagged: windows 8, ontario, low power, hondo, brazos, APU, amd

Thanks to a leak from AMD, we have new information on their plans for tablets and ultra mobile platforms.  Hondo will be a member of Brazos-T, the planned improvement to the current low power version of Brazos which goes by the name of Desna.  This is not so much a new chip as a refining of Brazos and the Ontario APU, the 1GHz APU will still be made on a 40nm process and sport a DirectX 11 GPU at 276MHz also optimized for lower power consumption and heat production.  The Hudson controller is also being tweaked in the same way, with the chipset's TDP sitting at 1W compared to the ~4W the APU will consume.  It should be capable of playing 720p videos at that power setting, though you can expect a bit more power draw if you are streaming the movie wirelessly.  You can read more about the future of the new fanless APU from AMD at The Inquirer.

"CHIP DESIGNER AMD is planning to refresh its Brazos platform in time for Microsoft's Windows 8.

AMD launched its Brazos platform last year, though actual products tipped up earlier this year featuring a dual core processor and a DirectX 11 GPU. However with Windows 8 coming out in 2012, it is a little surprising that leaked slides point to AMD planning a refresh of Brazos, codenamed Hondo. According to the slides, Hondo is designed to operate with passive cooling, and have 2W "app power" usage, about half that of the current Brazos chips."

Llano's dance card is available, pick a date with your favourite new AMD APU tomorrow

Subject: General Tech | June 29, 2011 - 11:29 AM |
Tagged: x79, release, llano, Intel, brazos, APU, amd

DigiTimes has announced that the 32nm Llano we've all be waiting for will be arriving tomorrow with the A75 chipset in tow.  A pair of A8s and a pair of A6's should be available for you over the next few weeks, with a refresh of less powerful A4 APUs set for the Fall/Winter of 2011.  The last quarter will also see AMD flesh out their lineups of A8 and A6 CPUs and the first arrival of the E-series for their Brazos platform. 

You'll have to wait a while longer for Scorpius, it is not scheduled to hit until the beginning of 2012, which means Intel's X79 chipset will be out along with a few new i3 and i5 models and even a new Celeron.

"CPU maker AMD is set to announce its latest 32nm A series APU codenamed Llano on June 30 with motherboard makers including Asustek Computer, Gigabyte Technology and Micro-Star International (MSI) all having announced products based on AMD's A75 chipset, according to sources from motherboard players.

In early July, AMD will initially supply its FM1-based A8-3850, A8-3800, A6-3650 and A6-3600 APUs with A6-3500, A4-3400, A4-3300, A8-3870, A8-3820, A6-3670 and A6-3620 APUs set for launch in the fourth quarter along with E2-3200. In September, AMD will also announce E-450 and E300 for its Brazos platform.

For the high-end Scorpius platform, AMD will announce the AM3+-based FX-8150, FX8100, FX6100 and FX4100 by the end of September with FX8170, FX8120, FX6120 and FX4140 set for the first quarter of 2012.

For chipsets, AMD will launch A75 (Hudson D3) and A55 (Hudson D2) together with its A series APU, and is set to launch a chipset codenamed Hudson D4 in February 2012.

On the other hand, Intel is also prepared to launch its high-end X79 chipset after September along with 11 upgraded CPUs including Core i5-2320, Core i3-2120T, Core i3-2130 and G540.

The sources pointed out that AMD is targeting Llano at the entry-level and mainstream markets, competing mainly against Intel's Core i3 and Pentium, while E-450 and E300 will target Intel's G440, 540 and 530 series."
