The Llano Desktop Preview: AMD A8-3850 CPU & GPU Performance
by Anand Lal Shimpi on June 14, 2011 12:00 AM ESTGPU Performance: Between a Radeon HD 6450 & 5570
I grabbed some of our most recent GPU testbed data for the Radeon HD 6450 and the Radeon HD 5570, the latter of which is architecturally most similar to the Sumo GPU in the A8-3850. If you're wondering how much sharing memory bandwidth between the GPU and four CPU cores impacts performance, it's pretty significant. The HD 6450 only has 160 cores compared to 400 on the 6550D, while the 5570 has 400 cores running at 750MHz.
Note that these scores are taken with DDR3-1333, however if we push the memory bus all the way to its limit on desktop (DDR3-1866) you end up with performance that's somewhere between a 6450 and a 5570. AMD's branding makes sense in this case (6550D).
Overall the Radeon HD 6550D in AMD's A8-3850 APU performs a lot like a discrete Radeon HD 6450 card. For a GPU that ships integrated with all high-end A8 APUs, I really can't complain. The real question is how does it stack up when compared directly to Sandy Bridge, which brings us to our next page...

What is called "serious gamerz" is 0.01% of users, but 99.99% of review websites visitors.Hence the eerie tone of most articles like "so can it do gaming or not" totally out of context when price, consumption, heat, technical elegance should be the matter.
The fact that an IGP that can do perfect bluray, perfect architectural or medical simulation, perfect graphic editing can be labeled "insufficient for serious users" is itself a subject of philosophical wonder, especially when you realize that what the "serious users" do is shooting at ridiculous zombies in extremely ugly environments.

Spot on!I think the issue is that AMD is listening and looking at what 99% of real world users actually use and need and catering to that.
Intel on the other hand have been totally blinded to follow the rants and needs of the 0.01% that read the review sites and their prices/power levels have gone up accordingly.
Its really only AMD's stubborn and baffling refusal to advertise to the masses that they obviously covet so much that holds them back.
Get enough TV ads up there and folks will be just as happy to ask for an AMD chip as an Intel especially when they find the AMD box is $100 cheaper.
If you dont advertise then its your own fault that you arent selling as much as the guy that does.

Given that both Intel's and AMD's IGP solutions are currently good enough for everything up to mainstream gaming I can't really see why AMD are doing a better job?Llano is obviously not fast enough to allow more serious work and the weaker per-core performance is going to be a drawback for most mainstream users who do browsing and word processing as their main tasks.
Llano seems to be lacking a significantly improved memory and cache system to truly make it shine, at least as far as GPU performance with 400 SPs go.

Are you serious? I can browse and do word processing on my ancient P4. Per-core performance doesn't matter for what the *vast* majority of users do on their computers. What kind of "serious work" requires something beefier than an Athlon II X4?And think a minute before you say "video encoding/transcoding", because soo few people actually do that, and those that do know what they need.

Gotta agree with 'veri745', mainstream users will not notice the performance difference.A 5 year old processor is just fine for your average PC user.

Yeah I've always felt that as soon as CPUs reached dual core to stop the eggtimer appearing with more then two windows open, that was it.The "need for more power game" ended for most folks at that point.
Customers just dont give a damn about CPUs on modern PCs. The thing that really wows them is show the the difference between a mechanical HDD and a SSD.
Now that they notice.

I think that an upgrade from an old pc (P4 for example) does have a noticeable impact on web browsing, text processors and so on, because these program are hungrier than before, but when you get certain amount of power, the bottleneck goes to the hard drive. So if you're browsing using a SB or a llano cpu, it wouldn't matter very much.jabber - Tuesday, June 14, 2011 - link
Good folks at Anandtech, is there any chance one of you could get an interview with the Marketing Dept Head at AMD and ask them exactly what is their strategy for getting into the hearts and minds of the general computing public?The dont seem to be bothering thats all.

I would guess they don't bother a whole lot because most people don't know or give a shit what the difference between Intel and AMD is. I know my mom and my sister don't. All they really care about is whether their computer can be used for email, browsing, and maybe occasional light photo/video editing with something like Windows Movie Maker or Photoshop Elements.jabber - Tuesday, June 14, 2011 - link
No thats note quite my point. As you say if mum and dad dont care but they only know of Intel due to them appearing on TV adverts 5 times a night which one will they go for?The Intel, cos they've never heard of AMD. You wouldnt buy a car and many other goods from a company you never heard of.
But you only have to get slight recognition and folks will be okay with it.
If you dont try you'll never know.
