NVIDIA GeForce GTX 670 Reviews, EVGA and Gigabyte

Introduction and Specifications

We really dig it when the two big discrete GPU makers are firing on all cylinders. Our workload may increase exponentially as NVIDIA and AMD volley grenades back and forth, but the excitement that’s generated as a result, is a rush for hardware guys like us. And if the overall engagement and comments posted by you all reading this are any indicator, action in the GPU space is exciting for you folks too.

After witnessing AMD release top-to-bottom, DirectX 11-class products, months before NVIDIA for the past few generations, it seems NVIDIA is done messing around. Hot on the heels of the impressive, dual-GPU powered GeForce GTX 690, which launched just a few short days ago, NVIDIA is already back with a much more affordable Kepler variant featuring a slightly pared down GK104 GPU. What’s perhaps most interesting to all of you though, is that this new card will offer near-GeForce GTX 680 performance, at prices starting under the $400 mark.

The new GeForce GTX 670 we’ll be showing you here today sports the very same chip that powers the high-end GeForce GTX 680 and 690, but with a few shader cores disabled. The cards will sport a more compact design and a few other tweaks as well. We’ve got NVIDIA’s full reference specifications below, followed by full details on the new card and a set of benchmark numbers with both single-card and SLI configurations on the pages ahead. Get yourself acquainted with the specs and then strap in as we show you what NVIDIA’s new baby can do...

NVIDIA GeForce GTX 670 Reference Card, Back

Before we give you the low-down on the GeForce GTX 670, we want to direct your attention to a few other HotHardware articles related today's launch...

We've already covered the details of the GK104 GPU powering the GeForce GTX 670 in our GeForce GTX 680 launch article, including things like GPU Boost, NVENC (NVIDIA Encoding Engine), and TXAA, so we won't go over them again here. If you'd like a deeper look into the technologies employed in the GK104, we'd definitely suggest taking a gander at that piece. The details of NVIDIA's brand new dual-GPU flagship are covered in our GeForce GTX 690 article, and our 3D Vision 2 and 3D Vision Surround articles cover those two NVIDIA technologies, which are obviously supported in a card like the GeForce GTX 670.
