System Specifications and CPU Performance

The systems allowed by AMD to be benchmarked by the press were ODM built – nothing branded or ready to sell quite yet. Still, the hardware itself seemed very competent and robust. Long the Achilles heel of AMD mobile processors, getting a high quality solution from a respected OEM is going to be a big deal for them.

Using one of the AMD FX-7600P APUs, our systems were top of the line when it comes to Kaveri mobility APUs. The APU has a top clock speed of 3.6 GHz and 35 watt TDP, putting it out of range of most of the Intel notebooks and Ultrabooks we had in our office, but we made due. The R7 graphics solution runs at a maximum clock speed of 686 MHz.

8GB of Crucial DDR3-1866 memory was running in a dual channel configuration and a Samsung 256GB SSD kept everything running snappy. Important when you are doing reference system testing.

The AMD Catalyst 14.3 drivers were loaded on a copy of Windows 8.1 and we were off to testing!

As I noted above, I did not have the best possible comparison notebook for the FX-7600P, which would likely be the Core i7-4702MQ, a Haswell CPU with a 37 watt TDP. Instead, we'll be looking at the Kaveri APU in a more general performance sense – how does it compare to processors that we know and understand today? You'll see numbers from some desktop system recently tested when looking at the 45 watt Kaveri A8-7600 as well as desktop options as high as the A10-6700T, a 45 watt part. 

Let's dive in.

CPU Performance

Starting things out is the traditional SiSoft Sandra testing that focuses on the x86 portion of the processor. Though it cannot beat the Core i3-4330 Haswell part, it gets DAMN CLOSE considering the 54 watt TDP of the Intel option! Multimedia results are much less impressive than the CPU arithmetic scores, but with a deficit of more than 2x on the memory bandwidth provided some other options tested, that makes sense.

CineBench 11 is a great test to judge the performance of the processor cores and the AMD FX-7600P does great here as well showing single threaded performance nearly as good as the A8-7600 desktop part and beating several previous generation parts. The Haswell processor still dominates though with a lead of 78% in single threaded performance. Multi-threaded results are better for AMD where that Intel lead shrinks to 45% or so and we see a more than 3x scaling rate from the FX-7600P single threaded score.

Though we only had time to get 2-thread and 4-thread results on the 7zip benchmark with the Kaveri reference system, again I came away impressed with the status of the mobile Kaveri solution.

Kaveri shows well in the x264 benchmark reaching within 19% of the Intel Core i3-4330 with a much lower TDP limit.
