ZOTAC NVIDIA GeForce GTX 750 Ti 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.

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.

Overclocking

  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.
