Synthetic Benchmarks

I was extremely impressed with the performance of the Diamond HD 7790 OC when compared to the other HD 7790’s that we have tested. The difference wasn’t huge but it was enough in 3DMark Fire Strike to jump from below the MSI overclocked GTX 650 Ti Boost to just slightly above it. As with the other HD 7790’s that we have tested, we had driver issues in 3DMark Fire Storm Extreme that had us questioning our results, until we get that resolved we aren’t publishing those results.

When it came to our Unreal Heaven 4.0 benchmark our results were similar to the 3DMark results where the Diamond card pulled ahead of the other HD 7790’s slightly, but this time it did not outperform the GTX 650 Ti Boost’s. This is due to the smaller frame buffer size, I would be interested to see where the Boost would be with a 1GB frame buffer or the HD 7790 with a 2GB buffer.

In our 3DMark 11 benchmarks things get a little more interesting. With the performance setting, we once again saw the Diamond HD 7790 outperform the overclocked MSI GTX 650 Ti Boost  and we actually saw numbers very similar to the 1.5 GB GTX 580 reference card, considering that the GTX 580 is still to this day a great card this was especially surprising. Part of that is due just to improvements in drivers from then until now, but it also shows how far we have come in card performance as well. In the extreme benchmark the Diamond card bested the other HD 7790’s but as expected performed a little lower due to its 1 GB frame buffer. It did still get up near the performance we saw with the HD 7850 though, an impressive result none the less.
