AMD’S LLANO ARCHITECTURE IN A NOTEBOOK ENVIRONMENT

Earlier this month we previewed AMD’s Llano design in a cover environment. Now we have a desktop chronicle with a 100 W TDP. How many a single some-more opening can a association gain with a loftier thermal roof and- aloft clocks?

Editor’s Note: As we’ve finished so many times before, we’re partnering up with CyberPower to give divided a single of a primary Llano-based desktop machines, which a builder calls a Gamer Ultra, to a single of a readers. Flip by a examination and-, upon a final page, come in to win a brand- new- PC, respect of CyberPower!

A8-3850 Makes Its Desktop Debut
Don Woligroski did an positively torpedo pursuit upon a primary demeanour during AMD's Llano architecture. If we haven't nonetheless review which story and- we wish to know some-more about a plumbing inside a company's primary mainstream APU, we unequivocally owe it to yourself to check out The AMD A8-3500M APU Review: Llano Is Unleashed prior to diving in to this piece.

Because- Don lonesome a underlying design so well, I'm starting to use- a primary practice with AMD's Llano-based desktop platform, code-named Lynx, to dive deeper in to a things we know we guys love: benchmark formula and- analysis. What kind of opening can we design out of Dual Graphics? How does Sand-y Bridge with dissimilar graphics compare? What outcome does mental recall opening have upon gaming await rates? How does integrated USB 3.0 await magnitude up to a little of a appendage controllers we've seen? I'll answer all of that.

But primary let's go over a basis of AMD's primary desktop-class Llano-based APUs.

Llano: The Recession-Friendly APU
 
Oh, Audi would be so unapproachable (or may be not, since a entry-level extraction of these processors). AMD is regulating a same A8 and- A6 designators to heed in in between a viewed opening levels of a 4 launch SKUs.

There have been dual A8s and- dual A6s. The Llano-based flagship is A8-3850, a 100 W partial with Radeon HD 6550D graphics, 4 execution cores with 1 MB L2 cache each, and- a 2.9 GHz time rate. That partial does not suggest Turbo Core support—the usually approach to get it using faster than 2.9 GHz is by overclocking. AMD says to design pricing around $135.

The A6-3650 is additionally rated during 100 W, even yet it's armed with Radeon HD 6530D graphics and- a some-more regressive 2.6 GHz time rate (again, Turbo Core isn't available). The -3650 boasts 4 cores as well, includes a same 4 MB of L2 cache, and- await DDR3-1866 interpretation rates, usually similar to a alternative 3 models. That a single is approaching to run $115.

That a single is approaching to run $115.
Model GPU TDP Cores Base CPU Clock Max. Turbo L2 Cache Shaders GPU Clock Turbo Core
A8-3850 HD 6550D 100 W 4 2.9 GHz - 4 MB 400 600 MHz No
A8-3800 HD 6550D 65 W 4 2.4 GHz 2.7 GHz 4 MB 400 600 MHz Yes
A6-3650 HD 6530D 100 W 4 2.6 GHz - 4 MB 320 443 MHz No
A6-3600 HD 6530D 65 W 4 2.1 GHz 2.4 GHz 4 MB 320 443 MHz Yes
Interestingly, dipping down to a 65 W turn doesn't appear to scapegoat many in a approach of functionality. AMD's A8-3800 includes a able Radeon HD 6550D engine, quad-core Stars architecture, and- 4 MB L2 repository. However, Turbo Core helps recompense for a sincerely serious dump to 2.4 GHz, kicking magnitude up to 2.7 GHz in situations where thermal headroom allows for it. Unfortunately, AMD didn't send over any Turbo Core-equipped processors for testing, so it's unfit to sign how many time this four-core partial spends during a towering setting.

Finally, a A6-3600 is additionally a 65 W component. It beam approach back, though, giving up not usually processor time rate—its 4 cores using during 2.1 GHz by default and- up to 2.4 GHz with Turbo Core—but additionally graphics opening around a less-complex Radeon HD 6530D engine. Is still includes 4 MB of L2 cache though, complementing any core with 1 MB.

What’s a difference, exactly, in in between a Radeon HD 6550D and- Radeon HD 6530D GPU engines? One SIMD engine, for a many part.
Graphics Processor Classification Radeon HD 6550D (A8-Series APUs) Radeon HD 6530D (A6-Series APUs)
Shader Cores 400 320
SIMDs 5 4
Texture Units 20 16
Render Back-Ends 2 2
Z/Stencil ROPs 32 32
Color ROPs 8 8
GPU Clock Rate 600 MHz 443 MHz
Peak Compute Power 480 GFLOPS 284 GFLOPS
When we demeanour during a retard blueprint of a Llano’s GPU component, it’s easy to see how AMD differentiates these dual lineups. Each SIMD hosts 80 ALUs and- is compared with 4 hardness units. Turning a single SIMD off yields a 320 shaders and- sixteen hardness units offering by Radeon HD 6530D.

A Small Launch Gets Smaller
 

With 4 SKUs in a primary Llano-based desktop portfolio, a zero-hour explanation which a 65 W A8-3800 and- A6-3600 won’t be accessible until an undisclosed date narrows a family down to dual models: A8-3850 and- A6-3650, both 100 W parts. As a result, it won’t be probable to exam Turbo Core functionality upon Llano until AMD addresses a accessibility of a lower-power offerings.
