ABT evaluates Galaxy’s GTX 780 V2

Performance summary charts & graphs

Here are the summary charts of 26 modern PC games and 3 synthetic tests. The highest settings are generally chosen and it is DX11 when there is a choice; DX10 is picked above DX9, and the settings are generally ultra or maxed unless specified on the chart. Specific settings are listed on the each performance chart. The benches are run at 1920×1200 and at 2560×1600.

In the first column of this abbreviated summary chart are the performance results for the Galaxy GTX 780 V2.  Column 2 shows our Galaxy V2 overclocked as far as it can go on stock voltage and with the stock fan profile.  Column 3 shows the R9 290X results at Uber clocks while the fourth column gives the results of the stock GTX 780 Ti.

We note that overclocking the Galaxy GTX 780 V2 brings it’s performance up to where it trades blows with the GTX 780 Ti and generally beats the R9 290X at Uber clocks.

There isn’t really isn’t any performance difference between the original reference GTX 780 and the Galaxy GTX 780 V2 when both cards are at stock clocks.  Here is a chart of our reference GTX 780 versus the Galaxy GTX 780 V2 using our most repeatable benchmarks:

The differences would fall into the margin of error for benching and are explained by the slightly different applications of Boost as applied by a altered fan profile in response to temperature changes.

Main Overall Summary chart – the Big Picture

The main summary chart is what we call ABT’s “Big Picture” as it shows performance from the GTX 760/R9 270X all the way up to the GTX 780 Ti and R9 290X.

In the first column of the main performance summary chart are the performance results for the Galaxy GTX 780 V2.  Column 2 shows our Galaxy V2 sample overclocked as far as it can go on stock voltage and with the stock fan profile.  Column 3 shows the R9 290X at Uber clocks, while the fourth column gives the results of the stock GTX 780 Ti.

Some of the detail setting have been lowered as noted on the chart by asterisks or parenthesis for the less powerful cards. The fifth column shows R9 270X compared with the GTX 760 in the sixth, while the last two columns show the R9 280X and the GTX 770.

In all cases, the Galaxy GTX 780 V2 is at least as fast as the stock reference GTX 780 and it further pulls away in performance as it is further overclocked and reaches slightly Boost than the reference version.  We ran both the V2 and the original GTX 780 at stock values, and even focusing on our most repeatable benchmarks, the results are almost identical.  They are well within the benchmarking margin of error even though Boost is applied slightly differently with a slightly altered fan profile for each card.

GTX 780 SLI Performance

Overclocking brings good scaling to the GTX 780 V2 and there is a performance improvement from each clock increase.  Here are the performance results of the stock reference GTX 780 paired with the stock-clocked Galaxy GTX 780 V2 in SLI compared with a single GTX 780 V2.

Generally GTX 780 SLI scaling is excellent at 2560×1600, but our Core i7 4770K would need to be overclocked beyond 4.0GHz to get the full benefit of GTX 780 SLI at 1920×1080 for some games.

We can see that the Galaxy GTX 780 V2 is a worthy replacement for the original Nvidia GTX 780 reference version.  Let’s head for our conclusion.
