Two GTX 780 GPUs that leave the reference model way behind to offer proprietary designs with better frequencies, improved cooling systems and more effective noise reduction.
Nvidia has done a great job with their reference models, but there is always room for improvement and the two models we’ll review today will demonstrate just that. These two graphics cards are a dream come true for those who want the absolute best; to improve the performance to the maximum level, they have high-end noise and temperature control systems. These models are the dream of every gamer, and today we will not only review them, but also pit them against each other and compare them.
ASUS Geforce GTX 780 DirectCU OC.
The design of this GPU is simply amazing. It’s quite bigger than the average graphics card, and the cooling system uses big nickel-plated copper heat pipes that transport the heat from the components through a massive aluminum-made radiation system.
The GPU has two different kinds of fans for the main and secondary systems. Both work at all times, but the rear one is slightly less efficient and powerful, which means it’s quieter, and since its only job is cooling the power supply, its design is simple. Both are the same size, but the main one is more powerful and features ASUS’ proprietary fan blade design, which can be found in the latest graphics cards from the manufacturer.
ASUS’ GTX 780 DirectCU II OC looks amazing, but it’s much bigger than the average GPU. It adapts to a double slot design, which is normal, but it’s much taller than normal and this may complicate its installation in smaller computers. This was one of the things Nvidia promised in regards to their reference models.
As for hardware, the GPU has 3GB GDDR5 slots for RAM. The frequencies have been increased to 889MHz and 941MHz in turbo mode, compared to the reference model’s 863MHz and 900MHz in turbo mode. It features 2304 shader engines, and the memory bus works at 6008MHz –the same as the reference model- and a 384-Bit data bus. That’s about 290GB/s of bandwidth.
The power supply unit consumes almost 300w, so it needs one 8-pin and one 6-pin plug. The connectivity includes double SLI bridge those three or up to four cards, and a frontal panel identical to the reference model’s with two dual-link DVI ports, one Displayport 1.2 port and one HDMI 1.4a port. It features digital sound and up to four monitors can be connected to it at the same time. It will cost 650 Euros.
Zotac Geforce GTX 780 AMP!
Zotac, of course, will give ASUS a run for its money. Its performance is amazing, as well as its impeccable design. Zotac’s GPU is slightly smaller than ASUS’ –both around 27 centimeters-, but it’s not as tall, as it doesn’t need extra space for a top-notch cooling system, which means this is an extraordinary GPU. Three fans and one massive hat sink make this a very heavy GPU. Two of those fans are secondary, and the main one is bigger and more powerful. The fans are controlled by the new Nvidia technologies, featured in their high-end models.
The card features a simple and efficient aluminum-made design; it has a big central fan that doesn’t make the card taller. This translates into a great performance and easy installation in small computers, Nvidia’s priority with these new reference models, designed with gamers in mind.
The performance of this GPU speak for it: It can offer simply spectacular results, this will be definitely a trend-setting GPU. It features an amazing frequency of 1006MHz, 16 % higher than the reference model, and a turbo mode of 1056MHz. Its 3GB of GDDR5 memory have been increased to 6208MHz, which translates into a bandwidth of 298GB/s. The rest of the features, like the 2304 shader engines, are the same.
It also has two dual-link DVI ports, one Displayport 1.2 and one HDMI 1.4 ports. The double SLI connector allows us to have up to four GPUs without consuming more than the standard 300w, so no more than two PEG power plugs are needed –one 8-pin and one 6-pin, like we said-. Zotac also includes a pack with three Tom Clancy Splinter Cell games so you can enjoy the power of this graphics card right away. It costs 670 Euros, and now it’s time to put it to test.
