The long-awaited launch of Intel’s Sandy Bridge is here, and we have all of the details of what to expect, what you need to “upgrade”, what models will be available at launch, and of course, their prices. We’re taking a look at two of the higest-end offerings, the Core i5-2500K and i7-2600K – both quad-cores and both fully unlocked.

Multi-Media: ProShow Gold, Sandra Multi-Media

While TMPGEnc XPress’ purpose is to convert video formats, ProShow from Photodex helps turn your collection of photos into a fantastic-looking slide show. I can’t call myself a slide show buff, but this tool is unquestionably definitive. It offers many editing abilities and the ability to export in a variety of formats, including a standard video file, DVD video and even HD video.

Like TMPGEnc and many other video encoders, ProShow can take full advantage of a multi-core processor. It doesn’t support SSE4 however, but hopefully will in the future as it would improve encoding times considerably. Still, when a slide show application handles a multi-core processor effectively, it has to make you wonder why there is such a delay in seeing a wider-range of such applications on the marketplace.

Our version of ProShow Gold is a bit aged at this point, but it still has what it takes to stress our processors, and once again Sandy Bridge delivers. The Core i7-2600K surpassed the performance of the Core i7-975 Extreme Edition in the DVD encode test, and lined up with the same result in the HD encode.

This test here stresses the CPU’s ability to handle multi-media instructions and data, using both MMX and SSE2/3/4 as the instruction sets of choice. The results are divided by integer, floating point and double precision, three specific numbering formats used commonly in multi-media work.

Just as we’d expect a synthetic benchmark to do, we’re given rather predictable results here. Interestingly, AMD’s Phenom II X6 1090T out-paces the Core i7-2600K in the integer test, but in the float and double, Intel’s chip soars ahead.
