Richland, code name for AMD's highest-end APUs, finds its way into our lab in the form of A10-6700 and A10-6800K. Based on the Piledriver architecture and VLIW4 graphics, these chips are slight improvements to Trinity. Can they outshine Core i3, though?
AMD's Kabini: Jaguar And GCN Come Together In A 15 W APU showed us what the company's Jaguar and GCN architectures could accomplish between 4 and 25 W TDPs. But, on the desktop, AMD isn't quite ready to make the leap to a next-gen design. It just introduced its desktop-oriented Richland APUs, which aren't really new at all. Rather, you can think of them as power-optimized Trinity parts, sporting the same Piledriver-based x86 cores and VLIW4 graphics configuration. Moreover, Richland-based APUs have been available to mobile device makers for months. The only real revelation is that we're getting this update in the desktop and low-voltage mobile spaces now.
| Model | Radeon | Package | TDP | CPU Cores | Base/Max CPU Clock | L2 Cache | Radeon Cores | Base GPU Clock |
|---|---|---|---|---|---|---|---|---|
| A-Series Low-Voltage and Ultra Low-Voltage APUs | ||||||||
| A10-5745M | HD 8610G | FP2 | 25 W | 4 | 2.1/2.9 GHz | 4 MB | 384 | 533 MHz |
| A8-5545M | HD 8510G | FP2 | 19 W | 4 | 1.7/2.7 GHz | 4 MB | 384 | 450 MHz |
| A6-5345M | HD 8410G | FP2 | 17 W | 2 | 2.2/2.8 GHz | 1 MB | 192 | 450 MHz |
| A4-5145M | HD 8310G | FP2 | 17 W | 2 | 2.0/2.6 GHz | 1 MB | 128 | 424 MHz |
In the table above, we see the new mobile-oriented options spanning 17 to 25 W TDPs. Richland isn’t much different from Trinity, but it's more efficient thanks to specific Turbo Core optimizations that include a greater number of P-states to facilitate more granular power and performance levels.
| Model | Radeon | TDP | CPU Cores | Base/Max CPU Clock | Total Cache | Radeon Cores | GPU Clock | Unlock | Price |
|---|---|---|---|---|---|---|---|---|---|
| A10-6800K | HD 8670D | 100 W | 4 | 4.1/4.4 GHz | 4 MB | 384 | 844 MHz | Yes | $149 |
| A10-6700 | HD 8670D | 65 W | 4 | 3.7/4.3 GHz | 4 MB | 384 | 844 MHz | No | $149 |
| A8-6600K | HD 8570D | 100 W | 4 | 3.9/4.2 GHz | 4 MB | 256 | 844 MHz | Yes | $119 |
| A8-6500 | HD 8570D | 65 W | 4 | 3.5/4.1 GHz | 4 MB | 256 | 800 MHz | No | $119 |
| A6-6400K | HD 8470D | 65 W | 2 | 3.9/4.1 GHz | 1 MB | 192 | 800 MHz | Yes | $77 |
And then we have the desktop-specific Richland parts. The very fastest model enjoys a 300 MHz base clock rate bump compared to the A10-5800K, along with official support for 2133 MT/s DDR3 memory (the other SKUs top out at 1866 MT/s memory). Also, its GPU is 44 MHz faster than the prior-gen version. And yet it fits within the same 100 W TDP.
On the other hand, the A10-6700 looks a lot like the -5800K, aside from a 100 MHz-lower base clock, a 100 MHz-higher Turbo Core ceiling, and a slightly quicker GPU. That one drops to a 65 W thermal limit.
Like the Trinity-based APUs before them, these Richland designs plug into a Socket FM2 interface. A BIOS update should be all that you need for compatibility with existing A55, A75, and A85 platforms.

And what about those shiny new Radeon model numbers? That's marketing being bad. We were already dealing with Radeon HD 7000-series naming on APUs, which was confusing because AMD's desktop 7000-series GPUs are commonly associated with the GCN architecture. Now we have 8000-series nomenclature. And yet, we're still working with the VLIW4 configuration that was around back when AMD was shipping Radeon HD 6900-series cards. Architecturally, the only difference between Richland's Radeon HD 8000 graphics and Trinity's Radeon HD 7000 graphics is the name.
Again, the top-end A10-6800K gets 2133 MT/s memory support, which is particularly meaningful for its on-die graphics engine given a lack of shared L3 cache. The theoretical 34 GB/s of DDR3 bandwidth should go a long way to improve frame rates in the games we'll be testing. With that said, let's move on to why we aren't able to test Richland's Dual Graphics feature today...

- As Expected, Richland Is A Little Better; Not Massively So
I guess Richland is still very hot going by the power figures alone. Still, it's a good step up (and stop gap) for AMD.
Nice review still. Are you guys planning on a follow up for Dual Graphics? 8)
Cheers!
No, since driver 13.1 even the 5800k was able to run dual graphics with a HD 7750. I am typing on a system with that exact setup right now. I am not sure if the 6800k will allow anything above the 7750 though. When I tried a 7770 with the 5800k I wasn't given the option to enable dual graphics.
Richland does appear to be just a refinement of Trinity. This review does explain why Kaveri desktop APUs are due to release at the end of the year.
I don't see why this argument is even made since both the 6700 and 6800K have the same MSRP considering that the only real difference in power consumption observed between the two chips was in gaming...
Your final graph suggests that the overall performance of the i3 is within margin of error of the A8-6800K(for which you didn't even bother to provide overclock benchmarks)
Lastly, can you confirm the MSRP? Your values seem to differ, other sources suggest $142 instead of your stated $149 (in fact, the pricing on all of the models seems to be off)
Isn't this a tech enthusiast site? The few reviews I've seen out there claim Richland overclocks better, cooler and higher then Trinity. Furthermore, they claim the overclocked igpu performs at the level of a 6670... which is a huge jump in performance... as the 5800k, even overclocked and with fast ram, was only about 70% a HD 6670.
where is the beef? Seriously i expected more from this site.
Secondly, the comment that Kaveri will require a new socket is largely unknown at this point - all that's been revealed is that it uses an "FM2+" socket - who knows what that'll mean in terms of mobo socket compatibility.

Hurry call amd tech support and tell them you have managed to accomplished what there high paid engineers have been unable to do.
I have no doubt that ccc is saying dual graphics option enabled but when you run benchmarks with it enable and disabled they are the same.
@Don, I have 3 queries for you.
Does Richland crossfire with 7750 (officially or unofficially)? If it does, that is sure an interesting thing to explore.
Also Don, yes even I've seen the figure of $142 floating around in other tech sites. Why do you quote it otherwise?
Lastly, you 'could' have added the Core i3 with Radeon 6670 in the power consumption charts just to show the increased performance in games and other applications comes with the added power consumption of the 6670 if it is present.
