Overclocking Galaxy’s GTX 750 Ti GC Slim without Limits

Performance summary charts & graphs

Here are the summary charts of 21 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 Main Performance chart. The benches are run at 1920×1200 and at 2560×1600.

Main Overall Summary chart

In the first column of the main performance summary chart are the performance results for the highly overclocked Sapphire Vapor-X HD 7770 which represents the performance of the HD 7790 and the R7 260.  In the second column is the GTX 650 Ti which debuted also at $149 and is the card the GTX 750 Ti is replacing.  Column three is the stock GTX 750 Ti and in column 4 is the stock Galaxy factory clocked GTX 750 Ti GC Slim.

In the fifth column (750 Ti OC) we present the reference GTX 750 Ti overclocked 135MHz as far as software allowed it, together with a +550MHz boost to the memory.  In the six column we see the GTX 750 Ti GC Slim (Galaxy OC) at +135MHz core/+600MHz memory offset to reach a Boost of 1337MHz.  The seventh column (Galaxy SC) is the software unlimited +160MHz core/+600MHz memory which reach a Boost of 1361MHz.  And the eighth column (Galaxy UL TDP) represents the completely unlocked TDP and clockspeeds which reached +168MHz core/600MHz memory offsets for an ultimate boost of 1369MHz.  The final ninth column is the $200-250 Radeon 270X (HD 7870 OC).We clearly see the GTX 750 Ti GC Slim dominate over the reference and mildly overclocked HD 7770s and also the HD 7790s/260s by extension. In most games in our 21-game benchmark suite, the GTX 750 Ti GC Slim is solidly faster than the reference GTX 750 Ti.

Overclocking brings good scaling and there is a performance improvement from each clock increase.  Overclocking it without limits makes up some ground on the R9 270X which is way out of its price class and even matches it in some  games.  Removing the TDP limits on the card only bring +8MHz more Boost to 1369MHz, but a lot more performance scaling than by just increasing the clocks by that very small amount.

And here is the PhysX “Big picture”

Let’s head for our conclusion.
