14 DAY TRIAL // NVIDIA's GeForce GTX 770 graphics card is already powerful, but that doesn't mean the company's OEMs won't tweak it anyway. Case in point, Palit has released the GeForce GTX 770 OC.
Obviously, the OC in the name stands for overclock. Sure, the clock modification isn't massive, but it's enough to differentiate the newcomer from all the others.
Speaking of which, the base frequency of the GeForce GTX 770 is normally 1046 MHz, while the GPU boost maximum is of 1085 MHz.
Palit's model runs at 1085 MHz and 1137 MHz, respectively. The company says this equates to up to 7% performance enhancement under DX11.
At least, tests in Unigine Heaven v2.5 benchmark at 1920 x 1200 resolution, nonAA/4AF, returned such results.
The 2 GB of GDDR5 VRAM memory were left alone though, which means their clock is the same old 7010 MHz (7 Gbps).
This much we could have guessed from the onset. Contrary to previous lines of video cards, today's AMD and NVIDIA adapters seem less prone towards total overclocking.
While the GPUs are sped up often, the memory isn't in the majority of cases. Possibly because there is no point in adding to the power load when those GDDR5 gigabytes are more than super-fast already. On that note, 7 GHz is the fastest GPU frequency ever anyway.
That said, Palit's GeForce GTX 770 OC graphics card gets DrMOS and copper-based chokes (stability in face of further overclocking), a 2-slot cooler with a copper base, 3-way SLI support, and 6-phase core PWM + 2-phase memory PWM.
All in all, the Palit adapter possesses a memory bandwidth of 224.3 GB/s and, of course, 1534 CUDA cores (as provided by the 28nm Kepler GPU). Palit will ship the product with the Thundermaster overclocking utility for a price of (probably) $400 / €400, regardless of what exchange rates say (€301).
