When Intel launched its Westmere-based line-up this past January, one of the more interesting models released was the Core i3-530. The big reason was its budget $120 price tag. But if there’s one thing that can make a budget chip interesting, it’s overclocking, and fortunately, there’s huge potential where this chip is concerned.
Photo manipulation benchmarks are more relevant than ever, given the proliferation of high-end digital photography hardware. For this benchmark, we test the system’s handling of RAW photo data using Adobe Lightroom, an excellent RAW photo editor and organizer that’s easy to use and looks fantastic.
For our testing, we take 100 RAW files (in Nikon’s .NEF file format) which have a 10-megapixel resolution, and export them as JPEG files in 1000×669 resolution, similar to most of the photos we use here on the website. Such a result could also be easily distributed online or saved as a low-resolution backup. This test involves not only scaling of the image itself, but encoding in a different image format. The test is timed indirectly using a stopwatch, and times are accurate to within +/- 0.25 seconds.
As Lightroom doesn’t seem to take full advantage of all the cores it’s given, the results here aren’t all too surprising. Lightroom is one area, though, where we find HyperThreading can be put to good use, and overall, the i3-530 performs very admirably here.
TMPGEnc Xpress 4.5
When it comes to video transcoding, one of the best offerings on the market is TMPGEnc Xpress. Although a bit pricey, the software offers an incredible amount of flexibility and customization, not to mention superb format support. From the get go, you can output to DivX, DVD, Video-CD, Super Video-CD, HDV, QuickTime, MPEG, and more. It even goes as far as to include support for Blu-ray video!
There are a few reasons why we choose to use TMPGEnc for our tests. The first relates to the reasons laid out above. The sheer ease of use and flexibility is appreciated. Beyond that, the application does us a huge favor by tracking the encoding time, so that we can actually look away while an encode is taking place and not be afraid that we’ll miss the final encoding time. Believe it or not, not all transcoding applications work like this.
For our test, we take a 0.99GB high-quality DivX H.264 AVI video of Half-Life 2: Episode Two gameplay with stereo audio and transcode it to the same resolution of 720p (1280×720), but lower the bit rate in order to attain a modest file size. This test also utilizes the SSE instruction sets, either SSE2 or SSE4, depending on what the chip supports.
The performance seen here isn’t worth getting all too excited over, but there are some things to point out. With the performance we’ve seen here from the i3-530, we pretty-well evened things out with the 3.16GHz E8500. That’s of course a last-gen chip, but at the time of its release, it was sold at $266. Here we have almost identical performance, but for $125 or less.
