Nvidia Debuts with GeForce GTX 770 Graphics Adapter

Trailed by the flagship GeForce GTX 780 model, Nvidia officially launches one more high-performance graphics adapter of 700 series, codenamed GeForce GTX 770. Albeit the two products are rather similar in design (i.e. the incorporation of identical two-slot cooling system), their layout differs considerably. First of all, GTX 770 employs less efficient graphics core Nvidia GK104-425-A2 (28 nm) with 1536 CUDA cores, 128 TMUs, and 32 ROPs. At the same time this GPU operates at higher frequencies: 1046 MHz (nominal), 1085 MHz (dynamic).

Nvidia’s new entry comes either with 2 GB or 4 GB video memory modules of GDDR5 type. They employ 256-bit interface and ensure high bandwidth of 224 Gb/sec. Memory operational frequency is truly striking, demonstrating up to 1752 MHz (nominal) and up to 7010 MHz (dynamic) index. It should be noted that models with 4 GB modules will cost $50 more than those with 2 GB items (the recommended price makes up $399).
