Gainward GeForce GTX 670 Phantom

Today marks the release of the GeForce GTX 670 GPU from Nvidia and we will be checking out a particularly interesting version from Gainward which is part of their elite Phantom series. Read on as we put the new GTX 670 to the test in more than a dozen video games...
Nvidia recently unleashed their Kepler architecture with the GeForce GTX 680 made its debut on the 22th of March. With the aim to deliver the worst fastest GPU for gaming Nvidia succeeded, beating the Radeon HD 7970 by a 7% margin according to our tests.
This forced AMD to reduce the MSRP of 7970 from $549 to just $479 making it 4% cheaper than the GeForce GTX 680. Reducing the price of their flagship GPU caused a snowball effect for AMD and we saw price cuts filter all the way down to the 7770.
The Radeon HD 7950 dropped from $459 to just $399 making it one of the most tempting 7000 series graphics cards, largely because it had no equal. However that is all about to change as Nvidia is today releasing the new GeForce GTX 670 with an MSRP of $399.
The GeForce GTX 670 is built from the DNA of the GTX 680 meaning that it utilizes the same GK104 GPU. There are many other similarities as well, for example it uses 2GB of GDDR5 memory which is again clocked at 6GHz while the new SMX units and GPU Boost technology is also being used.
On paper the GeForce GTX 670 doesnít look as though it is going to be a great deal slower than the GTX 680 and that could spell disaster for AMD. Nvidia says that although they are targeting the Radeon HD 7950 with their pricing they are actually going after the 7970 in terms of performance.
The GeForce GTX 670 ships with 1344 CUDA cores and 7 SMX units which is 192 less CUDA cores than the GTX 680 as there is 1 less SMX unit. There are also slightly less TAUís, 112 down from 128 while the ROPs remain at 32.
The memory subsystem of the GeForce GTX 670 is identical to the GTX 680, consisting of four 64-bit memory controllers (256-bit) with 2GB of GDDR5 memory clocked at 6008MHz (DDR). This means that the memory bandwidth remains at 192.2GB/s.
The Nvidia specification for the base clock frequency is 915MHz while the typical Boost Clock speed is 980MHz. Gainward has turned up the base clock frequency to 1006MHz while the GDDR5 memory now operates at 6108MHz boosting the memory bandwidth to 195.5GB/s though for the purpose of this review we will be testing this card according to the Nvidia spec for core and memory frequencies.
