AnandTech has published a comparison of the AMD-based Acer Aspire 5542 and Intel-based Gateway NV5933u. The processor, chipset, memory type and graphics card are all different, but otherwise the site has done its best to make this an apples-to-apples match up.
The specs are nothing to write home about, but pricing is obviously the driving factor. The Gateway NV5933u manages to pack in an impressive set of features for a list price of $550, including a Blu-ray combo drive (a $75 value). The Acer 5542 isn't the best example of an inexpensive AMD Athlon II M300 laptop, with a current price of $500 online. That makes the Gateway a clear value winner if you want Blu-ray support, but it's worth noting that you can often find similar M300 + 4GB laptops on sale for as little as $400. However, right now going off the retail pricing, we've essentially got a tie for pricing. That said, you won't find a non-Blu-ray i3-330M laptop for less than $550, and we wouldn't be surprised to see the NV5933u supply dry up shortly; the replacement NV59c looks to bump up the price to $749. Let's take a closer look at the two combatants before we get to the benchmarks.
