AMD APU’s (2011 – present)

AMD launches a new line of processors called the Accelerated Processing Unit (APU). It is, of course, a line of 64-bit processors, but is innovative because it’s designed to act as a CPU and GPU on a single chip (so, you’d have your regular CPU, but also an on-die GPU). The first generation of APUs announced in 2011 was Llano and Brazos. The former was designed for high performance situations while the latter was geared towards low-power devices. Trinity and Brazos-2 was announced in 2012 — Trinity for a high performance solution and Brazos-2, again, for a low-power offering. Kaveri was the third generation core, announced in early 2014 for high-performance. In the summer of 2013, Kabini and Temash were announced and intended for low-power hardware.

The AMD APU started out as just a project — the AMD Fusion project. It all started in 2006 when AMD wanted to create a system-on-a-chip (SoC) that combined the CPU with a on-die GPU. And that’s how the AMD APU got started.

There’s a lot of neat technology embedded in it — out-of-order execution, SSE5/AVX4 instruction, and they came on both the FM1 and FM2 sockets. It wouldn’t necessarily be surprising if you hadn’t heard of the AMD APU before, but despite that, it’s likely many tech enthusiasts and average gamers use the chip everyday. Both Sony’s PlayStation 4 and Microsoft’s Xbox One use custom versions of third generation low-power APUs.

AMD FX (2010 – present)

And then you have the AMD FX microprocessor. It’s most definitely not a successor to the AMD APUs, but something sold alongside them that directly compete with Intel’s Sandy Bridge and Ivy Bridge architectures. The AMD FX processors are actually geared more towards the high performance market, while the AMD APUs have a wider range of markets (low power and high performance) to cover.

One major difference between Intel’s Sandy Bridge and Ivy Bridge is that the AMD APUs don’t have integrated graphics. The integrated GPU is something AMD is keeping with its APU line. Still, the AMD FX is built off of the 32nm processor and AMD actually calls the FX series the first native 8-core desktop processor. As far as sockets go, AMD — for the most part — uses a single socket, the AM3+ for the FX series.  Some other things worth mentioning is that the FX series has the FMA instruction set and supports Open CL.

When it initially launched in 2011, it was built off of the Bulldozer microarchitecture. In 2012, the Piledriver architecture succeeded that. Both of these architectures use a modular design to put two-cores on a single module. But, another successor is coming in 2017 — the Zen microarchitecture. It will use the 14nm process, feature SMT (a version of Intel’s hyperthreading) and will employ the AM4 socket, which provides support for DDR4 RAM.

You can actually get a significant amount of performance out of the AMD FX series. All of the cores (or CPUs) in this series are all unlocked and overclockable, allowing you to seriously push the clock speed on these processors. For instance, using liquid nitrogen for cooling, the AMD FX-8370 was able to set a world record for clock speed — 8722.78MHz or a little over 8.7GHz.

Since the FX series are high performance processors, they also have a high TDP — up to a whopping 220W.

Intel offers some serious power with their currently line of Core i7 processors, but the AMD FX series takes the cake for the highest performance chips for consumer PCs. The drawback is that there’s no onboard GPU, but when you’re seeking power like this, you might rather have a dedicated video card anyway. It’ll certainly be interesting to see what 2017 and beyond brings with the competition between AMDs upcoming Zen microarchitecture and Intel’s Kaby Lake and Cannonlake architecture.


And that wraps up the timeline of the many different processors out there, at least for the time of this writing. Processor technology is an interesting concept, and if you read about the different CPUs, you’ll notice the trend of them getting smaller, yet more powerful. It’ll no doubt be interesting to see what we have in another 10 or twenty years down the road.

Keep in mind that this is a timeline we plan on keeping updated, so as new CPU generations release, be sure to check back here for new information!
