AMD recently launched their Kabini APUs and the A4-5000 has been reviewed by a number of websites. However, I haven’t been able to find a review that compares it to other x86 architectures at the same clocks. I happen to have a notebook with a AMD Llano based A8-3500M in it. This is a quad-core unit @ 1.5GHz, the same clock as A4-5000. Now, A8-3500M also has a boost mode that takes it to over 2GHz for some single-threaded workloads but I disabled that boost mode for this test. My Llano test system is running Win7 Home Premium (64-bit) and has dual-channel 8GB RAM installed. I don’t have a A4-5000 to test, so I referenced Anandtech for Cinebench 11.5 (64-bit multithreaded) and Mozilla Kraken, PCPer for Euler3D and Techreport for 7-zip.

Test results:

Test Jaguar Llano K10 Jaguar % of K10
Euler3D 0.971 Hz 1.41 Hz 68.9%
Cinebench 11.5 1.5 1.9 78.9%
Mozilla Kraken 6512.7 5883 90%
7-zip (compress) 3793 MIPS 5317 MIPS 71.3%
7-zip (decompress) 5397 MIPS 6152 MIPS 87.7%

For 7-zip, I just ran it as follows: 7z.exe b 3 -mmt4 -mmd25 as the default number of passes is way too long, but it should give us a decent idea :)

Overall, we are looking at between 70-90% of K10 performance at the same clocks in this test, which is quite good for a small dual-issue core. We don’t have any data on how the benchmarks scale with clock speed though. Hopefully that data will become clearer in the future when reviewers get their hands on the A6-5200 which has Jaguar cores clocked @ 2GHz.
