AMD A6 3650 Fusion: Perfect for HTPC

Today we tried another option in the desktop processor platform within the architecture of AMD Llano.


This is our second interaction with the new Lynx platform processors of AMD desktop equipment, we analyzed a series A6 model that has some differences in performance with the higher end models but maintain high levels of graphic processing and other key elements integration in the same “die.”

The A6 Performance Series, specifically the A6-3650.

The model discussed earlier under the higher range of these processors. The A6-3650 is placed just behind this model but has some technical limitations that differ from the previous model. The price difference between them is about $30, about 20%, so for this range of products the difference is important and it’s fair to value its performance in what it offers.

The A6-3650 integrates four processing cores manufactured using 32nm process where each core incorporates 1MB L2 cache. A conventional four cores are joined by a north bridge and a DDR3 memory controller. It can handle up to 16GB of 1866MHz DDR3 RAM and natively support 16x second-gen PCI Express graphics link.

The A6-3650 works with a frequency of 2.6GHz, without turbo mode keeps the TDP of 100W, where we can find a Radeon HD 6530D which has a working frequency of 440MHz and a total of 320 shader engines with DXVA support, OpenCL , DirectX 11, HD3D, etc. The integrated graphics card allows you to control two monitors simultaneously, with support for standards such as HDMI 1.4a pointers, and also it works in Crossfire mode with other basic models of the brand with the only condition that is to have 512MB of RAM available.

These processors use a new socket, the FM1, and work on the new AMD A75 chipsets. These next-generation chipsets add support for 6Gbps SATA and USB 3.0 natively and combined with the Processor North Bridge to support advanced technologies succeed as up to four GPUs Crossfire, etc.

The four USB 3.0 ports of our lab MB, an Asrock A75 Pro4, are supported natively by the chipset.

The graphics engine

This graphics engines enables the AMD APU to match the performance levels of entry-level models that are around, so far, 60-70 $. This model with 320 shader engines and support for multiple monitors and Crossfire Technology is virtually inaccessible by any  entry level graphics engine.

A card like the A6-3650 allows us to view HD video with almost no CPU usage, play games at average resolutions and medium-high qualities or even support our creative processes with input from general computing that these GPUs integrated into its own architecture .

Our computer happens to be a tightly integrated machine that limits consumption and reduces costs so it can be a good multimedia companion where a few months ago, one way or another we had to add a dedicated graphics engine.

This model also allows the processor to work with dedicated graphics in Crossfire mode.

Overclocking and graphics performance

Although these processors are not designed for overclocking, is not it’s niche market, it is true that we can get something out of it’s integrated turbo technology (although officially the A6-3650 has not turbo modes) to increase the processor’s internal multiplier to the 36x without having to modify any other system bus. This gives us a final frequency of 3.6GHz in a very simple system which provides 40% more speed.

Although the frequencies you see in our sceenshot reach 4GHz, which is rare since we assume that these processors do not have the multiplier released, the stable frequency, without changing voltages, which we considered fair is 3.6GHz.

Dirt2, with DirectX 11, moves in average quality at 1920×1080 points with FSAA 2x.

Team Fortress 2, the free trending game, moves in 1920×1080 points, with high quality, with 2x FSAA over 40fps constantly.

My dear Leaft 4 Dead 2 also holds good levels of high-quality FPS with 1920×1080 resolution and FSAA 2x points.

Playing a 1080p video with high bit-rate with an average consumption of 5% of CPU.

When using AMD APP to compress video the use of the CPU cores is reduced by half, leaving more resources free for other applications, and the process is accelerated by nearly 80% improvement.


Other features of the Lynx platform

This platform introduces many new features. Not only have a minimal graphics much more powerful than before. Its quad-core processors are fast, it’s remarkable storage capacity (in fact, is the first platform in the market that combines 6Gbps SATA RAID and USB 3.0 natively), great graphics extensibility (taking advantage of  theAPU graphics engine) and attractive prices.

This processor costs less than $130. A A75 board with all the good of this platform if around $80. It is $210 for processor, graphics card and motherboard. For less than $350 we can have complete towers that can have higher minimum yields than earlier generations and with a “standard” performance that have not even the most elaborate and powerful chipsets both AMD and Intel itself. We Save and win benefits, you can not ask for more.

AMD’s new processors are really versatile. These CPUs will not beat records but their strength and balance is got from a high quality GPU.


Analysis and Conclusion

The A6-3650 is a capable processor, although it  does not have much difference in price with the highest model of the new A8, but it allow us to have that we are lookinf for of these processors that is a quality multimedia device, sporadic quality game and get everything in a more integrated and budget format. We will start to see these processors in standard formats, and not in very thin HTPCs because their consumption is not for this, but these mini-ITX boards that allow us to very compact integrated PCs with high performance by taking advantage of this platform.

But focusing on the processor we found a somewhat less graphics power, but in my point of view it’s even enough, and an excellent overclocking potential. These processors and chipsets provide a complete platform for an excellent price.
