System Builder Marathon Q4 2014: Mainstream Enthusiast PC

Results: Synthetics

We begin our benchmark analysis with a handful of synthetic tests designed to emphasize differences between the various subsystems that changed between last quarter's configuration and this PC. With near-identical specifications with the sole exception being a GeForce GTX 970 instead of a GeForce GTX 770, we don't anticipate any deviations in the results except where the graphics card is involved.

Our first test highlights the point. The CPU-based physics score remains relatively static, but the new build's graphics score is world's better thanks to the GeForce GTX 970. Of course this has a large impact on the aggregate result, too, and the new build's stock result remains significantly better than the previous build's overclocked numbers.

The graphics card isn't much of a factor when it comes to PCMark, so there's not much to see here.

While the Kingston V300 SSD looks significantly slower than the previous system's Adata Premier Pro drive, remember that a mechanical hard drive result would be about 15 to 20 MB/s. It's still worlds faster than a conventional boot drive.

Identical processors give identical results in Sandra's arithmetic benchmark, no surprises here.

The cryptography Encoding/Decoding benchmark is accelerated by AES-NI, so performance is dictated by the rate at which system memory can feed data into the CPU. But both builds feature similar stock memory clocks and bandwidth, so there's no substantial difference.

As you can see here, both systems have very similar memory bandwidth at default stock 1600 MT/s cas 11 settings.
