AMD Pro A12 "Carrizo" Chip Offers TDP as Low as 12W

AMD's "Excavator" module could fetch big power dividends for the company, with the top of the line Pro A12 "Carrizo" APU for mobile platforms offering TDP as low as 12W (normal usage), going up to 35W (maximum stress). AMD allows users to set the TDP for their processors. Built on the existing 28 nm process, these chips offer TDPs as low as the ones offered by Intel, built on 22 nm and even 14 nm nodes.

This is made possible because "Excavator" features heavily compacted registers and decode engines, and AMD spent a lot of R&D kicking out redundant or useless components from the silicon. The recently launched A-Series Pro "Carrizo" APUs feature two "Excavator" modules (four CPU cores), a GPU with eight GCN 1.2 compute units (512 stream processors), 2 MB of total cache, dual-channel DDR3-2133 integrated memory controllers.

Dent1Fair enough. I do believe AMD intention was to have a alternative to hyper threading. In the original AMD press release documents even said that. Then they started to back track from this statement and started going down this real core gimmick.

Marketing wise they would have faired a lot better if they marketed their FX4xxx as dual cores and FX 8xxx as quad cores.
They did mention hyperthreading a lot and I agree. I have actually been looking at these A12's and I hope someone other than HP will release something using them. Preferably at 35w or in a chassis that could handle the 35w and attach a graphics card in there as well. In a 15" chassis with a 2k screen. Is that to much to ask?

PatriotAt 15w I see it outperforming the 5200u by 50-100% ...thanks for the links!
Don't know about that, but real world testing doesn't seem to indicate that. With actual shipping products Geekbench has the 5200U pretty much on par with the top AMD FX-8800P part

cdawallI'm hugely unimpressed. A core M-5y10 sits at a 4.5w TDP and will likely outperform this in everything but GPU performance and even then who is going to notice in the ultrabook market where the AMD chip will be throttling anyway.
Core M processors are not worth buying because OEMs lock the frequencies and until you buy the exact laptop model you do not know to what frequnecy OEM has locked the CPU.

As far as I am concerned I will consider the base frequnecy performance as final because I do not know to which frequency it was locked to but base frequency performance is guaranteed.

Geekbench is useless for graphics/gaming performance.
cdawallHP elitebook 755 G3 A12-8800B based. There are also several HP's that feature the FX-8800P, which is the performance variant (not business class CPU). It will not perform like the CPU you posted at 12w. Reviews already indicate that. It performs somewhere an i3 and i5 at that wattage, which happens to be similar to the Core M. Call it what you will, but underwhelming is what I call it.

Oh and since you can't apparently search.

Look into it a little harder and find the review of the HP running the CPU. I want you to find that for yourself. I would read it after a couple of beers because when forced into a 15w TDP envelope it gets is ass handed to it by the core M. Call it performance or call it junk either way at 12w it is underwhelming.
What's Core-M's DX12 IGP performance relative to FX-8800p's DX12 IGP at 15w?

FX-8800p beats Intel Core i5-5200U in gaming/graphics.

Considering the previous posts that mine were part of were aimed squarely at pro laptops - since the only Carrizo laptops actually listed are HP Elitebooks, I would have thought it was obvious I wasn't talking about a gaming system

That is AMD marketing slides. You see the BIG AMD logo in the corner. Of course they are going to say their product is the best.

It's mostly IGP benchmark test that can be replicated. LOL.

Toshiba Radius 14 has FX-8800p SoC.

My desktop Intel Haswells has IGP LOL.

The problem with that statement is graphics processor has clock speed and it needs plenty of memory read/writes to operate.

Also, you are forgetting
1. FX-8800p's 8 CU IGP would be a good solution to crossfire with 8 or 10 CU GPU. Surface Book form factor would be nice and AMD has problems with 2-in-1 form factors. AMD doesn't have a solution with 13 inch tablet with 15 watt APU/SoC and docking keyboard case's GPU. MS Surface Book with NVIDIA GPU would be a candidate for my next 2-in-1 tablet/laptop.

2. My 8870M is from year 2013 and has been overclock to 850Mhz via MSI Afterburner tool, hence beating year 2015 MacBook Pro's Radeon R9 M370X's 10 CU at 800Mhz.

The CPU performs like shit in a 15w TDP. I wouldn't want it in a surface.

Honestly way off topic, but if AMD wants to gain momentum in the CPU market all they need to do is start stuffing AMD stickers on the wii u, xbox one and PS4. People need the brand recognition and those are all components that work and work well.

As someone who has a big collection of laptops due to needing one at work and having to replace it every 3 ~ 4 years, what matters in a business laptop is single thread performance. GPU doesn't matter. All it needs is a good 2 core cpu with SSD along with 1080p. Some other goodies to have would be a secondary drive bay, easy access to internals so that I can get dust out and strong lid hinge.

In my case, lid hinge is usually the first to go (break down, I mean).

Then they might stop buying them too :cry:

I was refering to my HD7750, but yeah, SPs are only one part of the equation.
I wonder what is the "standard" CPU frequency.
