The new GeForce GTX 670, which is being released today, is a more affordable version of the GeForce GTX 680, costing USD 400 and, therefore, competing with AMD’s Radeon HD 7950. Let’s see how the SuperClocked model from EVGA fared in our tests.
The GeForce GTX 670 is based on the same architecture used by the GeForce GTX 680, called “Kepler,” is manufactured under the new 28 nm processor, has a dynamic overclocking technology, and supports the PCI Express 3.0 specification. The only differences between the GeForce GTX 670 and the GeForce GTX 680 are the core clock (915 MHz vs. 1,006 MHz) and the number of graphics processors (1,344 vs. 1,536). The memory configuration is the same.
EVGA is releasing five models based on the GeForce GTX 670: The stock model (USD 400), the SuperClocked model (USD 420), the FTW model (USD 440), the stock model with 4 GB of memory (USD 470), and the SuperClocked model with 4 GB of memory (USD 490).
In the following table, we compare the main specifications of the video cards included in our review. The prices do not include rebates and are for the models with the clock and memory configurations listed below. Prices were researched at Newegg.com on the day we published this review, except for the GeForce GTX 670 models, which are the prices advertised by EVGA and NVIDIA. We also included the GeForce GTX 580 in this review, as its price dropped from USD 500 to USD 380 – USD 430 in the past few weeks with the release of the GeForce GTX 680. NVIDIA also offers a 3 GB version of the GeForce GTX 580 starting at USD 490. The second clock listed under “core clock” is the maximum clock the GPU can reach using its dynamic overclocking technology (i.e., “boost clock”).
|Video Card||Core Clock||Shader Clock||Memory Clock (Effective)||Memory Interface||Memory Transfer Rate||Memory||Shaders||DirectX||Price|
|GeForce GTX 670||915 MHz/980 MHz||NA||6,008 MHz||256-bit||192.3 GB/s||2 GB GDDR5||1,344||11||USD 400|
|EVGA GeForce GTX 670 SC||967 MHz/1,046 MHz||NA||6,210 MHz||256-bit||198.7 GB/s||2 GB GDDR5||1,344||11||USD 420|
|GeForce GTX 580||772 MHz||1,544 MHz||4,008 MHz||384-bit||192.4 GB/s||1.5 GB GDDR5||512||11||USD 380 – 430|
|Radeon HD 7950||925 MHz||925 MHz||5 GHz||384-bit||240 GB/s||3 GB GDDR5||1,792||11.1||USD 380 – 425|
Today, only the LGA2011 Core i7 (“Sandy Bridge-E”) and the “Ivy Bridge” processors have a PCI Express 3.0 controller. Therefore, we tested the video cards using a Core i7-3960X processor on a motherboard based on the Intel X79 chipset. In our Radeon HD 7970 review, we discovered that, at this time, there is no difference between using a PCI Express 2.0 or a PCI Express 3.0 connection. We also discovered that if you are using a high-end video card, the CPU doesn’t affect gaming performance.
Now let’s take a complete look at the EVGA GeForce GTX 670 SuperClocked.
