Legit Reviews decide that they really wanted to be able to show the overclocking results you can expect from the AMD A8-3850, so they picked up eight of the chips to test each for overclocking ability.  There have been examples in the past of chips with a wide variety of overclocking limits which was often decided by the chip revision but not in all cases.  The test results show that all but two of the chips hit a stability issue when being pushed beyond 3679.5MHz, so you can take that as the most likely result that your chip will provide.  The two outlying chips will be exceptional, in one case in a bad way which you can see in the full review.

"When AMD released the 'Lynx' desktop platform back in June 2011, our motherboard reviewer ran into some bad luck when overclocking the processor. When you get a new platform setup for the very first time you really don't know what to expect and it does take some time to learn all the quirks and nuances of a new processor and motherboard. We recently ordered in six more processors and then overclocked all seven of them to see what the best one would be for our test system!"

Tagged: mobile, fusion, E-Series, APU, amd

AMD today announced three new Accelerated Processing Units (APU) to bolster up the mobile lineup. Specifically, two new E-Series and one new C-Series APU are inserting themselves into the lineup. The new chips bring enhanced graphic capabilities, HDMI 1.4a, and DDR3 1333 support. "Today's PC users want stunning HD graphics and accelerated performance with all-day battery life and that's what AMD Fusion APUs deliver," said Chris Cloran, vice president and general manager, Client Division, AMD.

According to MaximumPC, the new E-450 APU takes the top slot, bringing two CPU cores clocked at 1.65GHz, a Radeon HD 6320 GPU clocked at a base of 508MHz and maximum of 600MHz, and a power sipping TDP of 18 watts. The second new E-Series APU carries the same 18 watt TDP and dual CPU cores as the E-450; however, it is clocked at a lower 1.3GHz. Further, the chip’s Radeon HD 6310 GPU is clocked at 488MHz.  The new E-Series APUs feature battery life increases to the tune of up to 10.5 hours of Windows idle time.

The new C-Series APU is the C-60, and is a 1GHz dual core chip with a Radeon HD 6290 GPU. The APU is able to turbo its CPU cores to a maximum of 1.33GHz, while the GPU has a base clock of 276MHz and a maximum clock speed of 400MHz. Further, the chip has a 9 watt TDP, and boasts 12.25 hours of “resting battery life,” which AMD benchmarked using Windows Idle on a C-60 based netbook.

Currently, AMD has shipped more than 12 million APUs, and more than five million of the C-Series and E-Series processors in Q2 2011. More information on the specific benchmarking metrics AMD used can be found here.

AMD Accelerates APU OpenCL Performance With New SDK

Subject: Graphics Cards, Processors | August 8, 2011 - 08:28 PM |
Tagged: amd, APU, sdk, opencl

AMD released its new APUs (Accelerated Processing Unit) to the masses, and now they are revving the processors up with a new software development kit that increases performance and efficiency of OpenCL based applications. The new version 2.5 APP SDK is tailored to the APU architecture where the CPU and GPU are on the same die. Building on the OpenCL standard, APP SDK 2.5 promises to reduce the bandwidth limitation of the CPU to GPU connection, allowing for effective data transfer rates as high as 15GB per second in AMDs A Series APUs. Further performance enhancements include reduced kernel launch times and PCIe overhead.

Video Perspective: AMD Steady Video Technology on AMD A-Series APUs

Subject: Editorial, Graphics Cards | July 25, 2011 - 02:23 PM |
Tagged: amd, APU, llano, steady video, a8-3850, video

In our continuing coverage of the AMD Llano-based A-Series of APUs we have another short video that discusses and evaluates the performance of AMD's Steady Video technology publicly released to the world with the 11.6 driver revision this month.  Steady Video, as we described it in our initial AMD Llano A8-3850 review is:

Using a heterogeneous computing model AMD's driver will have the ability to stabilize "bouncy" video that is usually associated with consumer cameras and unsteady hands.

Basically, AMD is on the war path to show you that your GPU can be used for more than just gaming and video transcoding.  If the APU and heterogeneous computing is to thrive, unique and useful applications of the GPU cores found in Llano, Trinity and beyond must be realized.  Real-time video filtering and stabilization with Steady Video is such an example and is exclusive to AMD GPUs and APUs.

As you can see there are no benchmarks in that video, no numbers we can really quote or reference to tell you "how much" better the corrected videos are compared to the originals.  The examples we gave you there were NOT filtered or selected because they show off the technology better or worse than any others; instead we used it for what AMD said it should be used for - amateur video taken without tripods, etc.  

And since this feature works not only AMD A-Series APUs but also on recent Radeon GPUs, I encourage you all to give it a shot and let us know what you think in our comments here below - do you find the feature useful and effective?  Would you leave the option enabled full time or just turn on when you encounter a particularly bouncy video?

If you haven't seen our previous Video Perspectives focusing on AMD A-Series of APUs, you can catch them here:

Intel and AMD Provide Positive Earnings

Subject: Editorial | July 22, 2011 - 01:59 PM |
Tagged: Sandy Bridge E, Q2 2011, llano, Intel, bulldozer, APU, amd

 

The first half of this year has been surprisingly strong for the chip industry, and Intel and AMD are helping to lead the way and satiate demand for new processors at all market levels.

Intel was first off the bat to release earnings for their 2nd quarter, and they again broke revenue and profit records for Q2.  Gross revenue was a very healthy $13 billion and the company’s net profit was an impressive $3 billion.  Margins are down from last year’s high of 67%, but the actual 61% far outshines that of their competition.  Q2 2010 results were $10.8 billion in gross revenue and $2.9 billion net profit.  While profit was “only” $100 million more than Q1 2010, the extra $2.2 billion in revenue is something to sit up and notice.

Sandy Bridge based parts have continued to propel Intel's domination of the CPU market.

Probably the two greatest strengths for Intel are extracting the most amount of performance per mm squared of die and of overall process technology leadership.  Intel has been shipping 32 nm parts for some 18 months now, and their redesigned Sandy Bridge architecture has left their primary competition in the dust when it comes to overall multi-core CPU performance.  Intel has improved their integrated graphics capabilities, but this is one area where they simply cannot compete with the more GPU focused AMD.  Intel is also facing much increased competition in the mobile market from the Llano based chips and their accompanying chipset, which has been a virtual fortress for Intel until recently.  While Intel still rules in CPU performance, the combination of rich graphics, chipset features, and competitive power consumption has made Llano a true threat to the mobile sector.

Overclockers Achieve Impressive Llano Overclocking Results, Come Close to 5GHz

Subject: Processors | July 18, 2011 - 11:15 PM |
Tagged: superpi, overclocking, LN2, llano, APU, amd, a8-3850

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.

ssoc1.jpg

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.

vsoc2.jpg

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?
