Since the introduction of GCN-based Southern family graphics cards, AMD has always bathed in the glory of victory, HD 7970 features great improvement in 3D games or universe compute, the 28nm process brings surprising power consumption control and overclocking capability.
In the whole DX11 era, AMD always possess starting-release advantage, but the later-release NVIDIA could change this situation, such as GTX 480 vs HD 5870, GTX 580 vs HD 6970. After the three months away from HD 7970 introduction, NVIDIA Kepler finally arrives, the battle has begun.
Compared with GTX 580, GTX 680 features more CUDA cores totaling the amount of 1536, the texture increases to 128, while ROP decreases to 32, less than 48 of GTX 580. In addition, the memory interface falls from 384-bit to 256-bit. The memory frequency of GTX 680 reaches 1502MHz, surpassing 1375MHz of AMD, the total memory bandwidth is 192GB/s, slightly higher that GTX 580, but there features still some gap with 384-bit of HD 7970.
The most evident improvement lies in power consumption and die size, GTX 680 features die area of only 294mm2, much lower than 520mm2 of GTX 580, also lower than 365mm2 of HD 7970, even much lower than the current 360mm2 of GF114 core. In addition, the card features only 195W TDP, while HD 7970 and GTX 580 feature 210W and 244W, respectively, which is absolutely the top-grade core with the smallest size, lowest power consumption for NVIDIA since GT200 architecture.
Did GTX 680 will change the idea that NVIDIA graphics would always be one that features high performance and great heat? What change will the card come with? CUDA core advances three ranks and power consumption is slower instead, now let’s disclose the Kepler architecture.
