14 DAY TRIAL // NVIDIA doesn't have a new high-end graphics adapter to counter AMD's Hawaii-based Radeon R9-290X board with, but that doesn't mean it and its partners, in this case PNY, are going to lie down and hold their peace while AMD launches that beast live.
Case in point, PNY technologies has formally launched the GeForce GTX 770 OC and GTX 780 OC graphics cards.
Both of them support NVIDIA TXAA technology, NVIDIA FXAA, NVIDIA Adaptive Vertical Sync, and 3D Vision Surround (multi-monitor setups in 3D).
PNY is targeting gamers who, whether due to money limits or some other reason, don't have the means to get a GTX Titan.
Coincidentally, those who can’t afford a Titan won't afford AMD's fast-approaching R9-200-series card either, so there shouldn't be any effect on the demand for the new duo.
Anyway, the GeForce GTX 770 OC and the GTX 780 OC have 2 GB of GDDR5 VRAM (each), and custom-designed dual / triple fan coolers.
We may as well lay out all the specifications, since we're on the topic. The former, being the “modest” one, has GPU clocks of 1,150 MHz / 1,202 MHz (base / GPU Boost) rather than NVIDIA's 1,046 MHz / 1,085 MHz. Meanwhile, the 2 GB of VRAM run at 7.2 GHz, vs. 7 GHz.
As for the GTX 780 OC, it functions at 1,006 MHz / 1,059 MHz for the GPU (base/boost), vs. 863 MHz / 900 MHz. The memory is set at 6.9 GHz (not 6 GHz).
Thus, the former has a memory bandwidth of 230.4 GB/s and a texture fill rate of 134 billion texels per second, and the latter manages 297.9 GB/s bandwidth and 160 billion texels/second.
Finally, the GTX 770 OC has 1,536 CUDA cores and dual-DVI, HDMI, and DisplayPort outputs, while GTX 780 OC boasts 2,304 cores and the same video connectors. Sales should be underway for £344.99 / €399 / $399 and £524.99 / €629 / $629, respectively.
