AnandTech: ". . . it's more like an underclocked or lower binned Snapdragon 600"

So, Qualcomm might have struck again.  First, there was a wee controversy when Samsung debated its flagship a couple months back and the processor might not have been what Samsung/Qualcomm said it was.  

 

Now, we may have that again.

 

See, the Nexus 4's S4 Pro features 4 Krait 200 processors.  Logically, the Nexus 7 would as well, right?

 

Nope.

 

 

 

Rather than the relatively logical upgrade path of going to NVIDIA’s Tegra 4 SoC (I’ve heard all manner of speculation about what happened there), the new Nexus 7 switches to Qualcomm’s APQ8064–1AA, a version with 4 Krait 300 CPU cores (yes, Krait 300, not 200) running at up to 1.5 GHz and Adreno 320 graphics. Rather than use a PoP and LPDDR2, this specific APQ8064 variant goes to PCDDR3L–1600 MHz instead, including 4, 4Gb discrete 1.35V SK-hynix DRAM devices off to the side (more on the opposite side of the PCB) adding up to 2 GB of RAM. Qualcomm's Snapdragon S4 Pro and Snapdragon 600 branding gets confused here, although Qualcomm is calling the APQ8064 inside the Nexus 7 (2013) S4 Pro, it's more like an underclocked or lower binned Snapdragon 600.

 

Which really is all well and good, because...

 

 

 

Suffice it to say, moving from 1.2–1.3 GHz Tegra 3 to 1.5 GHz APQ8064 represents a big jump forwards in performance. Google claimed 1.8x improvement on CPU performance, and 4x improvement on GPU, which gets validated pretty much consistently through the benchmarks. I never felt like Tegra 3 was a slouch by any means (performance was more I/O bound on the OG Nexus 7, which we’ll talk about in a moment), but the new Nexus 7 has ample performance for the considerable increase in screen resolution.
