Review: Worthy GTX 680 substitute
Upon Nvidia’s launch of GTX 670 graphics cards, Gainward already had two products to compete with. Today we’ll show you a special model – Gainward GTX 670 Phantom 2GB. The other GTX 670 we mentioned is based on reference model and clocks.
Nonreference coolers are quite popular and Gainward’s Phantom series has always been a standout product in that respect. The series boasts some nice overclocks as well, not least due to quality cooling.
GTX 670 Phantom’s GPU ticks at 1006MHz while the memory is at 1527MHz (6108MHz effectively). Note that reference clocks are 915/1502MHz for the GPU/memory.
While GTX 680 comes with eight SMX units and 1536 CUDA cores, GTX 670 has seven SMX units and 1344 CUDA cores. Coincidentally, reference GTX 680’s GPU runs at 1006MHz, which is the exact clock of our Gainward GTX 670 Phantom.
The card packs eight memory chips totaling at 2GB of GDDR5 memory. Good news for Nvidia fans is that the company kept the identical memory system used on its GTX 680 card, meaning four 64-bit memory controllers (256-bit memory interface) and 2GB of GDDR5 memory. The company didn’t change memory clocks compared to the GTX 680, and it stands at 1502MHz (6008MHz effectively) on reference GTX 670 cards.
