When hard drives densities measured in the megabytes or single-digit gigabytes, data compression became something that even the layman computer user took advantage of. In fact, even entire hard drives could be used in compressed mode to help increase the overall storage. Today, such methods aren’t required thanks to hard drives ranging in the thousands of gigabytes, but compression is still used on a regular basis by many people, either for storing a folder for backup, encoding music, converting a photo and et cetera. On servers, compression is often used to shrink mega-large log files.
For our compression testing, we enlist the help of 7-zip 9.20. We take a 772MB folder that consists of 39,236 highly-compressible files and archive it using an ‘Ultra’ level of compression using the LZMA2 algorithm. This results in an archive weighing in at about 137MB.
The differences between the i7-3770K and i7-4770K are about as minor as it could get, but the six-core CPU once again shows that in some tests, it can truly excel.
In terms of complexity, Euler3D is one of our most advanced benchmarks, and also one of the quickest to run. It calculates the fluid dynamics properties of the AGARD 445.6 aeroelastic test wing as it was tested in-house at NASA’s Langley Research center. It’s calculated using Euler equations, with results printed out as Hz and time-to-complete (seconds). A benchmark such as this is useful to those who work designing products where physics has to be considered, whether it be a wing, a car, a ship and so on.
The scaling exhibited here is just about what we’d expect to see at this point.
