ZOTAC GeForce GTX 750 Ti OC Edition Graphics Card Review
Power, Temps and Overclocking
For idle power we list the full system use at the wall after sitting at the desktop with no activity for 5 minutes. Load power is the highest reading we saw for the full system when testing during this review. Temperatures are taken in the same way. Noise levels are taken after a period of prolonged gaming in a scenario which applied maximum load to the GPU. Finally, our CPU is running at full MHz when testing, speedstep etc disabled.
| Idle Power |
Load Power |
Idle Temp |
Load Temp |
|
| ZOTAC GeForce GTX 750 Ti OC | 149w | 201w | 30°C | 62°C |
| NVIDIA GeForce GTX 650 Ti OC | 148w | 213w | 24°C | 53°C |
| AMD Radeon R7 260X OC | 146w | 240w | 34°C | 65°C |
Based on the documentation on Maxwell from NVIDIA we should expect to see some impressive power use figures here and that turns out to be the case. The 750 Ti leads the way on load consumption, dropping the 650 Ti figure by 12w and beating the 260X OC by nearly 40w. At the same time the GTX 750 Ti also runs cooler than our custom cooled Radeon, though the Windforce cooler on the 650 Ti is exceptional and leads the way.
Overclocking
Overclocking our card is a simple process, install Zotac’s Firestorm application and tweak a few settings to enhance performance.
| Max OC (Core/Memory) | |
| ZOTAC GeForce GTX 750 Ti OC | +90 core +86 memory |
| 3DMark Stock | 3DMark Overclock | |
| ZOTAC GeForce GTX 750 Ti OC | 1973 | 2080 |
Our sample was able to overclock by around 90MHz on the core and 86MHz on memory (voltage tweak applied too) and that gave us a final 3DMark score of just under 2100 points for Fire Strike Extreme.
