HP Leaks Three Unreleased AMD A-series APUs
by Kristian Vättö on September 7, 2011 11:35 AM ESTHP has accidentally leaked three AMD A-series APUs while updating the service guide for HP Pavilion g7. The update simply includes SKUs and specs for three yet to be released APUs, which suggests that HP will be utilizing these APUs in Pavilion g7 at some point. All three are mobile variants like the M at the end suggests. Below is a table of AMD's A-series mobile lineup - the unreleased CPUs are in bold.
| AMD A-Series Mobile Lineup | |||||||
| Model | Core/Thread Count | Frequency | Max Turbo | L2 Cache | IGP | IGP Frequency | TDP |
| A8-3530MX | 4/4 | 1.9GHz | 2.6GHz | 4MB | HD 6620G | 444MHz | 45W |
| A8-3520M | 4/4 | 1.6GHz | 2.5GHz | 4MB | HD 6620G (?) | 444MHz (?) | 35W |
| A8-3510MX | 4/4 | 1.8GHz | 2.5GHz | 4MB | HD 6620G | 444MHz | 45W |
| A8-3500M | 4/4 | 1.5GHz | 2.4GHz | 4MB | HD 6620G | 444MHz | 35W |
| A6-3420M | 4/4 | 1.4GHz | 2.4GHz | 4MB | HD 6520G (?) | 400MHz (?) | 35W |
| A6-3410MX | 4/4 | 1.6GHz | 2.3GHz | 4MB | HD 6520G | 400MHz | 45W |
| A6-3400M | 4/4 | 1.4GHz | 2.3GHz | 4MB | HD 6520G | 400MHz | 35W |
| A4-3320M | 2/2 | 2.0GHz | 2.6GHz | 4MB | HD 6480G (?) | 444MHz (?) | 35W |
| A4-3310MX | 2/2 | 2.1GHz | 2.5GHz | 2MB | HD 6480G | 444MHz | 45W |
| A4-3300M | 2/2 | 1.9GHz | 2.5GHz | 2MB | HD 6480G | 444MHz | 35W |
Some of the specs have a (?) after them because those specs were not found in the HP datasheet, but they are our guesses based on the other models of that family. All in all, it looks like A8-3520M will be A8-3500M with 100MHz higher clock speed and Turbo, A6-3420M is A6-3400M with 100MHz higher Turbo and A4-3320M is A4-3300M with 100MHz higher clock speed and Turbo. Increasing the frequency multiplier by one is a pretty common way of delivering smaller updates between bigger updates like die shrinks and micro-architecture changes, so this is nothing special.

So TDP is lower in spite of higher frequency ? This doesn't make much sense :(Kristian Vättö - Wednesday, September 7, 2011 - link
The difference in frequency is so small that it shouldn't dissipate that much more heat. It's the case with Intels too, you get a minor clock speed boost but the TDP stays the same. Of course, power consumption in real world is higher but TDP is only directional anyway and meant for OEMs.Taft12 - Wednesday, September 7, 2011 - link
It does if you know what TDP actually means.DanNeely - Wednesday, September 7, 2011 - link
The base frequencies for the new parts are lower than their equivalent last generation 45W equivalents. Peak turbo levels are higher, but turbo is only sustained at max level until the chip gets too hot; with stock cooling this is generally not a 100% duty cycle.The next question is if AMD will be refreshing the 45W parts with higher clocks, or if those were just a way to do something with hot running dies.
PS If you compare the new 35W parts to the old ones, both base and max turbo numbers are unchanged or up.

TDP varies in large steps (for AMD, is 45, 65, 90 and 125W I think). So you might have two 65W processors, one consuming 64W and one consuming 46W.Also, the power consumption might go down if the newer, faster processors use a lower voltage.
