Benchmark Results: Productivity

Core i7-2820QM: Sandy Bridge Shines In Notebooks

ABBYY’s FineReader 10, an optical character recognition app, was another requested benchmark. We’ve automated the scanning of a 111-page document for testing—a task that apparently really appreciates parallelism.

The top two finishers are quad-core, Hyper-Threading-enabled CPUs, and third place goes to the i5-2500K.

It takes almost five minutes, which is about two and a half times longer, to complete this workload on Arrandale-based chip compared to the Core i7-2820QM. The other dual-core processors fare no better, with times about two times that of the i7-2600K.

We phased out WinZip a while ago. But with the release of WinZip 14, Intel got the developer to include AES-NI support. So, we’re putting it back into rotation, alongside the latest versions of WinRAR (no AES-NI support) and 7-Zip (free to use; includes AES-NI).

We suspected in our desktop coverage that WinZip hasn't been optimized for threading, and it shows again with the Core i7-2820QM. It actually falls behind the Clarkdale-based desktop processor here, since performance is based almost exclusively on IPC throughput and clock rate, rather than parallelism. Note to self, use something else.

There is a clear tendency toward the Sandy Bridge-based processors. Yet, it looks as if multi-threading will only get you so far here. This may just be a development issue, as 4.00 is still in beta. We'll know for sure once it goes gold.

Parallelism really benefits the 7-Zip metric, which we set to take advantage of all available threads on each CPU.
