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...

Also for gaming. Hopefully Llano prices will end up a little lower than rumoured, otherwise might as well buy an Athlon II X4 635 + Radeon HD 6570 ($160 together at Newegg).Exodite - Tuesday, June 14, 2011 - link
What do you mean?That the general populace does/doesn't buy computer with gaming in mind?
Because from these numbers Llano is as incapable of handling gaming as any other IGP. Aside from casual gaming, flash games and the like, but then again every IGP can handle that.
The bare minimum for gaming is doing native resolution, meaning 1080p today, at low-medium settings with no AA at tolerable framerates.
I'm not seeing that here.

I mean that Llano is also disappointing for gaming. I thought it was clear from context, but apparently it wasn't. I'm glad you've agreed with me.Still, I disagree with your assertion regarding bare minimum gaming. WoW at 720p is probably what separates a gaming capable PC from one that isn't.

Re: WoW, granted.I just feel WoW is a poor representation of the GPU prowess of Llano as the game is by far and large CPU-bound, as most MMOs, RPGs and RTSs are.
Shooters are by far and large the common denominator for mainstream gaming.

WoW is the single most mainstream game out there....Other titles I would consider mainstream are Call of Duty, Fifa, Portal, Minecraft...
I'm pretty sure all of these titles would get 100 fps in Llano

By the way, I think Llano could have a place where space is a premium, such as nettops and all in ones. The main problem here is power consumption and heat, and I wonder if the desktop Llano will be good enough in these respects.Mathos - Tuesday, June 14, 2011 - link
Whats the story on chipset plans for the Llano chips? Are they going to do a 990GX chipset that could be run in crossfire with the APU's GPU? Can these GPU's in the processor be used for hybrid crossfire the same as the GX chipset iGPU's can, for example with a discreet 6550?milli - Tuesday, June 14, 2011 - link
"However Intel does have a history of building upon ideas that AMD introduced before their time (e.g. IMC, x86-64, Fusion), "AMD didn't invent IMC.
AMD didn't invent 64bit computing.
AMD didn't invent Fusion (well they did invent the brand name).
So please, don't mix things up. Don't think that Intel only looks at the x86 market for ideas. Having some of the old Alpha & Elbrus people there, i don't think they're short on ideas. It's just when they want to implement them.

So who exactly invented x86-64 if not AMD? Perhaps it didn't invent "64 bit computing", which is a completely irrelevant argument, but it did invent the most far reaching enhancement of the x86.Lonbjerg - Tuesday, June 14, 2011 - link
"but it did invent the most far reaching enhancement of the x86. "You say that like it's a good thing?
x86 should have died years ago.
