ZOTAC NVIDIA GeForce GTX Titan Review

Power, Temperatures, Noise and Overclocking

Starting with our power tests it is worth noting that current generation products manage this aspect in a different way to older cards so we have changed the way we test power and temperature levels in our reviews. 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.

NVIDIA GTX Titan 204w 461w 34°C 81°C 44db
NVIDIA GTX 690 213w 543w 33°C 80°C 52db
NVIDIA GTX 680 2GB 191w 386w 33°C 76°C 48db
AMD HD 7970 OC CrossFire 198w 621w 40°C 71°C 56db
AMD HD 7970 OC 188w 383w 36°C 62°C 47db

As noted above these figures are taken during out real world testing (gaming) and overall the figures are as we would expect. GTX Titan draws significantly more power than the 7970/GTX 680 however less than a GTX 690 with its dual GPUs. As the default configuration for the Titan is to remain at 80c or lower the load temperature is not surprising, and reasonably close to the GTX 680 however the real stand out result is the noise level where the GTX Titan is easily the quietest of all the products tested.

Overclocking the GTX Titan is a simple process; we open PrecisionX (or any compatible tool) and through moving a few sliders can increase the performance of the card.

Overclock Settings Overclock Settings

  Max OC (Core/Memory)
NVIDIA GTX Titan +174MHz GPU, +125MHz Memory
(106% Power, 94°C Temp Limit, 1.2V)

  Power/3DMark Stock Power/3DMark Overclock
NVIDIA GTX Titan 461w/4609 531w/5192 (45.5db)

Our overclocking tests showed that it was entirely possible to max out the power/temperature sliders without issue… and the voltage tweak option too. With those in place we hit +174MHz on the GPU and +125MHz on memory with full stability. This gave us an increase of around 70w at load for power use with the noise level only rising by a small amount. 3DMark however was more noticeably impacted with a nice increase of nearly 600 points.
