Back in 2014, John Byrne (Former SVP and GM of AMD Computing & Graphics Business Unit) revealed the new Carrizo lineup of APU’s.
Recently the whole Carrizo lineup got leaked ahead of ISSCC 2015.

first up lets take a look at the Carrizo’s structure :
We have two Excavator modules, aka four CPU cores, and four GPU modules aka 256 shaders as inferred form the next two slides.

One more thing to note in the slide above is that AMD managed to achieve a 5% IPC Gain even after a 23% reduction in die size while staying on the same 28nm node as before. They did this by implementing something called the High Density Libraries(HDL). Although this is a long standing norm in the GPU side of things I am seeing this first time on the CPU side.
In laymans term HDL packs more transistors per mm of die area through tighter layers,as a result the processor becomes more power efficient at the cost of speed.
So basically
- IPC Gains
- 23% reduction in die size
- Better battery life.
Now coming to the actual lineup, they were spotted in sata-io.org .
The lineup will consist of the following
- AMD FX-8800P
- AMD PRO FX-8800B
- AMD A10-8700P
- AMD A8-8600P
- AMD A6-8500P
- AMD PRO A10-8700B
- AMD PRO A8-8600B
- AMD PRO A6-8500B
- AMD RX-418GD
- AMD RX-216GD
Among them partial specs of FX 8800P is known thanks to a 3DMark result,while its pretty vague in details it lists the APU as a 12 Compute Cores enabled part which confirms that the Carrizo APU on mobility will feature a maximum of 4 x86 Excavator cores and 8 GCN Compute units forming into the 12 Compute Cores.
I will end this boring post(for some) with a screengrab of 3Dmark 11 score of the upcoming APU.
So what do you guys think of the new Carrizo? Let me know about it in the comments below.
