AMD A6-3650 Llano APU Performance Review - HotHardware

AMD A6-3650 Llano APU Performance Review

17 thumbs up

Desktop Llano APUs, like the A6-3650 we'll be featuring here use AMD’s FM1, 40mm x 40mm, lidded packaging as opposed to the FS1, 35mm x 35mm, lidless packaging of the mobile variants.


AMD A6-3650 APU In a Hard Candy Shell

While Llano APUs look very similar to current Phenom II and Athlon II processors from the top, thanks to the similar lid and integrated heat spreader installed on the chips, they use a completely different pin configuration and also a different socket. Desktop Llano APUs have 905 pins on their underside whereas socket AM3 Phenom II and Athlon II processors have 939 pins.

 
AMD A6-3650 CPU-Z and GPU-Z Details

The AMD A6-3650 APU has a default CPU clock speed of 2.6GHz (26 x 100MHz). It has four x86 cores each with 128 KB L1 Cache (64KB Instruction, 64KB Data) and 1MB of L2 per core—no L3 cache is present. Current Phenom II processors have similar L1 configurations, but only half the L2, plus a large 6MB L3. The larger L2 should help mitigate the loss of the L3, along with some other improvements to the cores. The 32mn “Stars” derived cores in Llano have improved schedulers and branch predictions units, along with some other low-level tweaks that result in an approximate 6% improvement in IPC performance over current-gen Phenom II processors.

There’s not much to see with regard to the integrated Radeon HD 6530D GPU core in the GPU-Z screenshot that we haven’t already talked about. To reiterate, the GPU core runs at 443MHz and has 320 shader ALUs arranged in 4 SIMDs. The fifth SIMD that’s active in A8-series APUs is disabled on the A6-3650, and other A6-series parts.

Though its a great step by AMD, it still feels like the product is lacking the, "oumph" factor. Sure the integrated GPU performance is wonderful, but apart from that, its got nothing special. Most folks can do wonders with an i3 and lets say, a AMD 5450 or the most barebones low end GPU.

The low power is also nothing fantastic.

Its a good honest review, But I dont know, it may receive HH's Stamp of Approval, but it doesnt get Coolice's Stamp of approval. That being said, i'm just a lowly student who doesnt know much about computers =D

@Coolice - Price out a Core i3 build with discrete graphics. And then price out a 3650 build. You'll see why it then gets the stamp of approval.

Good performance for an entry level PC. I see nothing wrong with these new AMD APU's at all.

I bought an A8-3850 along with an ASRock F1 board, just to check it out and see if it was  a viable solution. Not long after I had it up and running, my Wife's Dell crapped out (PSU) and I put the AMD A8 box in it's place while I repaired the Dell. Two days later I brought the Dell back and she told me that She was keeping the AMD box, "thank you very much".

No, this is not a democracy, but it's still good. Smile

Thanks for the great review and I'm looking forward to seeing more Llano notebook reviews in the coming months.

@ realneil ; What does your wife use her computer for mostly? Did you or does she do any gaming with it?

She's getting her Masters Degree through online studies.

I gamed with it a bit without any discrete card in there and it was OK,......If I turned the eye-candy down a little bit, it played all of MY games at decent rates.

When I added a XFX Radeon HD6870 Black to it, things were pretty cool. I didn't do benches with it, but I noticed that the XFX card worked better in it, than it did in the previous system. (a X-2 Phenom 3.0 GHz.)

Thanks for the info. I'm thinking of building one of these since it fits into my budget. I'm not what you'd call a hard core gamer but I do want to be able play games.

It's quite unfortunate that you can't add better discrete cards. There's just a bit of power missing in my opinion. Sure it will fit some people but a little more power would make a huge deal for gaming. You wouldnt have to choose between high resolution with ok framerates and low res thats 100% fluid.

That also, or mainly actually, goes for mobile.

Another great review Marco things played out as I had imagined, Intel wins on a pure x86 standpoint while AMD wins on the GPU front.

Again I see more users gravitating toward the Fusion APU as CPU speed at this point in the industry is good enough. Eye candy is what it's all about now days with I-Pads and other slates such as Motorola Zoom and such in the market also HP just released one as well.

Still hope Bulldozer can close the gap some on the CPU front but that is going to be tough as Ivy Bridge will be there to greet it.

These things will game, just not on MAX settings. Add another HD6000 series GPU to it and it will combine with the onboard graphics to really speed things up. If you're a hard core gamer and want the fastest parts you can get, you need to spend some more money than this costs.

great review. As more of a power user, this isn't necessarily what i'd go for, BUT i definitely cannot wait for their next generation of APU tech.
