So instead of having lesser number of higher clocked units, NVIDIA now has more lower clocked units. In the Fermi architecture, the shader clock operated at twice the base clock speed. One of the main reasons behind a jump in the number of CUDA cores is that NVIDIA have decided to do away with the shader clock unit completely. In Kepler GK104 GPU, the SM is called SMX and the math goes something like this: 192 CUDA cores housed in 1 SMX 2 SMX per GPC and 4 GPCs make the GPU.įor the GK104 GPU (Kepler) that equates to 192 x 2 x 4 = 1536 CUDA cores, which is a huge jump from 32 x 4 x 4 = 512 CUDA cores seen on the GF110 GPU on the GTX 580. In the GF110 for instance, there are 32 CUDA cores housed in 1 SM 4 SM make 1 GPC and 4 GPCs make the GPU. The graphics Processing Cluster has dedicated resources for rasterization, shading, texturing, computer and a majority of the GPU's core graphics related functions are performed within the GPC. Looking at the basic architecture of the Fermi GPU, you will notice that it goes from CUDA Cores → Stream Multiprocessor (SM) → Graphics Processing Cluster (GPC). Let us first try to understand what is under the hood of the card. It has managed to keep the maximum TDP at 195 Watts which is much lower than 244 W seen on the GTX 580. The GTX 680 is made of 1536 CUDA cores and the card has 2 GB of fast GDDR5 memory clocked at 6.006GHz.
The base clock has been set to 1008MHz, with a Boost Clock speed of 1058MHz. The GeForce GTX 680 GPU is based on TSMC's 28nm manufacturing process and houses 3.54 billion transistors. We couldn't wait to try it out, specially since the AMD flagship card had scored better than NVIDIA's GTX 580 in most benchmarks. ZOTAC was kind enough to send us the ZOTAC GeForce GTX 680 card for review. The new GPU is codenamed Kepler and it improves upon the Fermi GPUs.
GPU ZOTAC NVIDIA GTX 680 SERIES
NVIDIA announced its flagship single-GPU based graphics card in the new GTX 600 series day before yesterday. The long wait for the next-gen NVIDIA graphics card series is finally over. Update: ZOTAC GTX 680 pre-bookings have started.
