Introduction

NVIDIA's much talked about Kepler GPU architecture is finally testing waters in the crucial performance market-segment, with the GeForce GTX 670. The new graphics card, as NVIDIA puts it, is built from the DNA of GeForce GTX 680. This launch closely follows that of the GeForce GTX 690, which is the posterboy of the Kepler GPU architecture, and is the fastest graphics card ever made. The GeForce GTX 670 is designed to let NVIDIA capture the US $399 price point, its competitor is meant to be Radeon HD 7950, although its specifications give us hope that the SKU could fry both bigger and smaller fish than that. It could target the Radeon HD 7950, as well as take a shot at scoring a higher price-performance than the much cheaper Radeon HD 7870 GHz Edition.

The GeForce GTX 670 utilizes the same 28 nm GK104 silicon, with one streaming multiprocessor (SMX, amounts for 192 CUDA cores) cut out, resulting in a CUDA core count of 1,344. The GPU clock speeds are also toned down a tiny bit, with 915 MHz core, and 980 MHz GPU Boost frequency, but the memory clock speed (of 6.00 GHz, resulting in 192 GB/s bandwidth) is left untouched. It packs 112 texture memory units (TMUs), and 32 raster operations processors (ROPs). The GeForce GTX 670 retains the entire feature-set of the GTX 680, including 4-way SLI support, and the ability to drive four monitors by a single card (and hence 3D Vision Surround).



ZOTAC's GeForce GTX 670 AMP! Edition comes a premium GTX 670 implementation. The card uses the exact same PCB, cooler, memory and other components as the ZOTAC GTX 680 AMP! Edition. ZOTAC has increased clocks of their card by a large amount to exploit their custom design as much as possible.


Important: All data in this review was obtained after I repaired a major design error of the card. When I received it, the card ran extremely high temperatures, reaching beyond 100°C. This is caused by screws with integrated stop, that resulted in too little mounting pressure between GPU and heatsink. I added four metal washers, by removing the screws, adding the washer and putting the screws back. The cooler was not removed for this procedure, thermal paste was not changed.

The Card

ZOTAC's huge cooler has heatpipes sticking out the top. Make sure the card fits your case!


ZOTAC is using a triple slot cooler on their GTX 670 AMP! Edition.


Display connectivity options include two dual-link DVI ports, one full-size HDMI port and one full-size DisplayPort. You may use all the outputs at the same time, thanks to NVIDIA Kepler's new display output controller.

An HDMI sound device is included in the GPU, too. It is HDMI 1.4a compatible which includes HD audio and support for Blu-ray 3D movies. The DisplayPort outputs are version 1.2 which enables the use of hubs and Multi-Stream transport.


You may combine up to four GTX 670 cards from any vendor in a multi-GPU SLI configuration for higher framerates or better image quality settings.
