GeForce GTX 770 SAC 4GB / GD770-4GERX

One of a few ELSA Graphics Processing Units, based on NVIDIA GeForce GTX 770, ELSA GeForce GTX 770 SAC 4GB (part number GD770-4GERX) is built on 28 nm manufacturing process. The card is aimed at desktop market. The graphics card runs at 1.07 GHz, and supports boost technology, that can increase operating frequency up to 1.1 GHz. Furthermore, it has 1536 CUDA cores, 128 texture units, as well as 32 ROPs. The GeForce GTX 770 SAC 4GB embeds 4 GB of GDDR5 memory, using 256 bit bus. The memory is clocked at 1.75 GHz, which results in 224 GB/s memory bandwidth. The GPU has PCI Express 3.0 interface, and needs 2 slots on the motherboard. The maximum power draw of this model is 195 Watt, same as on the reference design. The ELSA GeForce GTX 770 SAC 4GB is compatible with SLI technology, and will work together with other graphics cards (up to 3 in total) for an extra 3D graphics and gaming performance.
