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).



MSI's GTX 670 Power Edition uses the famous Twin Frozr IV cooler from the MSI Lightning and comes with a large clock speed boost out of the box, making its default clock speed even higher than GTX 680 stock clocks. MSI is asking a $30 price premium for their card, which doesn't look unreasonable, given the improved cooling and higher clocks.

The Card

Graphics Card Front
Graphics Card Back

We've seen MSI's Twin Frozr IV heatsink design on other cards before, it covers the whole card to maximize cooling potential. Unlike the MSI Lightning, the cooler does not extend beyond the edges of the PCB, so the card should easily fit most cases.

Graphics Card Height

The card is using a dual slot cooler.

Monitor Outputs, Display Connectors

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.
