Intel Core i5-3427U: Ivy Bridge For Ultrabooks

SiSoftware SANDRA and PCMark 7

We continued our testing with SiSoftware's SANDRA 2012, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2012 suite (CPU Arithmetic, Multimedia, Cache and Memory Latency and Memory Bandwidth).

SANDRA Processor Arithmetic and Multimedia Tests

SANDRA Cache and Memory Latency and Memory Bandwidth Tests

In these quick synthetic tests the new Ivy Bridge ULT dual-core shows it's actually able to keep pace with previous generation standard voltage/power chips and in some cases even surpass them.  Memory bandwidth is also showing a slight advantage for the Core i5-3427U chip.

Futuremark PCMark 7
General Application and Multimedia Performance
Next up, we ran our test systems through Futuremark’s previous generation total-system performance evaluation tool, PCMark Vantage. PCMark Vantage runs through a host of different usage scenarios to simulate different types of workloads including High Definition TV and movie playback and manipulation, gaming, image editing and manipulation, music compression, communications, and productivity.  Since we have a database of scores for this test, we felt it would be good to give you additional reference points to compare to.

Keep in mind we're showing you reference scores versus previous generation Sandy Bridge Utlrabooks primarily here.  However, each of these machines are also configured with fast SSDs, which affects the score in PCMark 7 significantly since it's a rather disk sensitive benchmark. Recently, this new crop of Ultrabooks has chalked up top end scores in this benchmark as a result of their SSD storage subsystems primarily.  Dual-core versus dual-core its no contest, Intel's new Core i5-3427U Ivy Bridge CPU puts out impressive performance, almost doubling scores seen from previous generation Ultrabooks (Toshiba's rather slow SSD in the Portege Z835 actually gets lapped and then some), and leaving the AMD Trinity-based prototype in its rear view.
