At the peak of NVIDIA’s graphics cards is GK104, better known as Kepler or GTX 680. GeForce GTX 670 is still Kepler in its essence but with less power and a cheaper price. It rivals AMD Radeon HD 7950. NVIDIA claims it is more powerful than the best AMD processors and we are here to find that out.

Design

It’s rarely that we see top-tier graphics cards come in slim packages and GTX 670 is just that. It is compact and lightweight much like GTX 680. It measures only 7 inches long if we exclude the PCIe bracket. GeForce GTX 670 is equipped with one DisplayPort, one HDMI port, and two separate DVI outputs. Shown off during its unveiling is a dual-slot design but NVIDIA remarks some of their partners are opting for single-slot options.

Technically speaking, GTX 670 is GTX 680 because it uses the same GK104 chip. Unlike 680, it has one Streaming Multiprocessor (SM) unit turned off and reduced to 112 texture units from 128. It does keep the 32 ROPs of GTX 680, staying true to its roots.
Specs

GTX 670 has 12% less cores. 192 CUDA scores were nicked off, to be exact, in favor of the lower price point. It is also clocked at the lower 915MHz frequency making it 12% slower than GTX 680. These downgrades are minimal and keeps the graphics card on top-chart performance.
Performance

NVIDIA GeForce GTX 680 underwent preliminary benchmarks and was compared to GeForce GTX 580 and Radeon 7950. It was first tested with 3DMark7 to assess how it performed against its predecessor and rival.
