The Guru of 3D published a review on the ASUS GeForce GTX 780 STRIX 6 GB Graphics Card
A quote from the article:
For today's review we test the all new and hip GeForce GTX 780 STRIX 6 GB Graphics Card from ASUS. The customized product is equipped with a redesigned air cooler. This new unit comes with 6 GB graphics memory (rather handy with Watch Dogs if ya wanna play in ultra image quality settings eh ? And yeah, a sporty new design cooler. As you will see, the DNA of the DirectCU II cooler is still there, but the design is a little bit more well .. let's call it military ?ASUS GeForce GTX 780 STRIX 6 GB Graphics Card Review @ Guru3D
Surprisingly, the STRIX packs a GTX 780 GPU, not a 780 Ti. So the more 'regular' GeForce GTX 780 is being used. This means it is based on the GK110 GPU and has a whopping 7.1 Billion transistors. That makes it a nice chunk faster opposed to the GeForce GTX 680 GPU. Just like Titan, the GTX 780 is based on the GK110 GPU with the distinctions that the Titan has a GK110-300 GPU and the GeForce GTX 780 a GK110-400 GPU. Same stuff, yet with some things disabled. The GK110 chip is BIG, and that makes it a difficult chip to bake, its recipe is refined though as the product has 2304 Shader Processing Units, 192 TMUs and 32 ROPs on a 384-bit memory interface of fast GDDR5. So yeah, NVIDIA trimmed down that 45 mm × 45 mm 2397-pin S-FCBGA Titan with its 2688 shader/stream/CUDA processors a bit, whereas the 780 Ti is unlocked. Memory wise you are looking at 3 GB over 6 GB, that is still huge (12 pieces of 64M ×16 GDDR5 SDRAM) of memory (384-bit) on there and started designing a bunch of new tricks at BIOS and driver
So the ASUS GeForce GTX 780 STRIX has your typical standards like 2304 CUDA Cores. The GTX 780 is based on the GK110 GPU with the distinctions that the Titan has a GK110-300 GPU and the GeForce GTX 780 a GK110-400 GPU. Same stuff, yet with some things disabled. 2304 Shader Processing Units, 192 TMUs and 32 ROPs on a 384-bit memory interface of fast GDDR5. The card comes with dual-DVI, HDMI and DisplayPort outputs and will be available in two versions - one with stock clocks and one with an overclocked GPU (as tested today). The GeForce GTX 780 STRIX 6 GB STRIX edition comes with that updated cooler called that packs two dust-proof fans. Interesting is that Strix drives the DirectCU cooler to run at 0dB, the fans actually stops spinning completely when the GPU temperature is below 70°C And during heavy loading Strix still performs 20% cooler and quieter opposed to the Nvidia reference (according to ASUS). The GPU is powered by an 8-phase (digital) power design. DIGI+ VRM digital voltage regulation helps with overclocking capabilities, which are further supported by the use of hardened Super Alloy Power components fitted onto the PCB.
