AMD A10-6800Ok and A4-4000 Richland APU Assessment

At the end of last year, we tested AMD's desktop version of Trinity, which includes Piledriver CPU cores and an integrated graphics processor from the Radeon HD 7000 series (not Graphics Core Next).

The family was headlined by the A10-5800K with four cores clocked at 3.80 GHz, a 4 MB L2 cache and the Radeon HD 7660D. This was one of four quad-core Trinity parts that were provided at launch, along with two dual-core APUs known as the A6-5400K and A4-5300.

The A10-5800K made its debut with an MSRP of just $ 130 and was then against the Core i3-3220. The end result was a typical battle between Intel and AMD. While AMD had a clear advantage in terms of GPU performance, the CPU side of things was more controversial.

In the end, we came to the conclusion that Trinity, like Llano before, was a bit soft when it came to processing horsepower, even though it was a quad-core part. On the other hand, the integrated graphics performance was unmatched.

Overall, Trinity started where Llano left off and provided an affordable package with enough processing speed for most users, while enough graphics muscle was provided in modest settings for most PC games today.

Now, just over 6 months later, AMD is updating its product range with a small update. These new APUs, codenamed Richland, offer no major changes to either the CPU or the GPU. Except for some clock speed improvements, better power management, and some new software features, everything is the same.

So we're not going to cover all the features of Richland architecture because they are very similar to Trinity. Instead, we will quickly introduce the new models to you before we jump into the benchmarks.

At the top of the table is the A10-6800K, which, as you may have guessed, replaces the A10-5800K. With a few exceptions, both processors are identical. The A10-6800K clocked a bit higher at 4.10 GHz than at 3.80 GHz, while the turbo frequency was increased from 4.20 GHz to 4.40 GHz.

The Radeon HD 7660D has been replaced by the 8670D for the A10-6800K and offers an increase in the operating clock rate from 800 MHz to 844 MHz. That being said, as far as we can tell, the 8670D and 7660D are identical.

The A10-6700 replaces the A10-5700 and again it is similar. The A10-6700 is only enjoying a slight increase in frequency. There is also the A8-6600K and A8-6500, both quad-core parts with Radeon HD 8570D graphics, a new solution with 320 cores.

The dual-core parts include the A6-6400K, A4-6300 and A4-4000. All of them only have 1 MB of L2 cache. The A6-6400K comes with Radeon HD 8470D graphics, while the A4-6300 uses the 8370D and the A4-4000 uses the same 7480D graphics silicon as the old A4-5300.

Today we're taking the A10-6800K flagship for a spin along with the A4-4000 bargain basement on the other end of the spectrum, which we suspect will be a slightly slower version of last year's A4-5300.
