Data compression and decompression

You see, it gets better already.

And since there's nothing much to discuss here, let's say a few words about the difference between Atom D510 and Atom 330. These two have very similar processor core architecture and same cache, so it would seem that a difference in performance should be on a par with the difference in clock rate (about 4%). In fact, it's as much as 9%. But as you remember, ASRock A330ION occupies nearly 1GB of RAM for its integrated graphics, while ASRock AD510PV, when there are no considerable tasks, needs only 10MB thanks to DVMT (i.e. it can have more if needed). That is perhaps the reason for such a difference in performance between these two testbeds. Of course, compared with the results of Zacate E-350, not to mention those of Athlon II X2 250u, the whole matter seems rather insignificant.

Audio encoding

Note that audio encoding is handled by relatively simple algorithms (compared with video encoding, for example). They do not require that large amounts of data be processed in memory and so their performance mostly depends on processor core. Even cache size is barely important. We remind you of that, because this group of benchmarks is the only one where Atom outperforms Zacate. And now you know why: because audio encoding is almost perfectly parallelized in our test method (thanks to dBpoweramp), and Atom has 4 cores thanks to Hyper-Threading.

Compiling

If you still remember the final rendering and data compression diagrams, here's another very similar one. It indicates that, sadly, the difference between specialized and regular CPUs remains no matter what area of application is involved.
