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).

HP Employs Processors AMD Athlon II X2 221 and Sempron X2 198

The release of hybrid AMD processors of A series was announced about a year ago, however, their actual appearance in the market was delayed for a few months. It is a well-known fact that a part of those processors for Socket FM1 platform has got idle graphics block; this part of processors has been codenamed Athlon and Sempron. The two processor models from this series Athlon II X2 221 and Sempron X2 198 can be currently found in PCs manufactured by HP company.



Both processors have been observed in the list of specifications of desktop PCs delivered by HP: Athlon II X2 221 is employed in HP Pavillon p6-1169cx and p6-1226cn models, while Sempron X2 198 is employed in HP Pavillion p6-1152cx, 1230cx, 1231cx, and 1159cx models. The major peculiarity of such technological solution is that HP PCs with those processors are delivered only to the Chinese market.
