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).

At present many companies produce VR-compatible portable PCs performed in the shape of a backpack. Most of them are designed for gaming purposes; however, HP developers believe these systems can be also useful in professional spheres.



At the SIGGRAPH 2017 conference, HP presented its wearable HP Z VR Backpack workstation, resembling a backpack. The manufacturer claims it to be the most effective among similar devices due to the 4-core Intel Core i7-7820HQ mobile CPU, operating at the 2.9–3.9 GHz frequency, and the high-end mobile NVIDIA Quadro P5200 video card, based on the Pascal GP104 graphics processor with 2,048 CUDAs and the 16 GB GDDR5 memory. Storage capability is ensured by the 32 GB DDR4-2400 RAM and up to 1 TB SSD.


A couple of hot swap 55 watt-hour batteries enables HP Z VR Backpack wireless productivity. This HP specialty can operate as a desktop system while connected to a special docking station.

GeForce GTX 1080 and GeForce GTX 1070 GameSoul series graphics accelerators by Gainward are ready for release. These products are meant for powerful game-playing machines and VR systems.



Graphics cards are based on the 16 nm NVIDIA GP104 chip with Pascal architecture. The GeForce GTX 1080 model has 2,560 streaming processors, 160 TMU and 64 ROP. The card features 8 GB of GDDR5X memory with a 256-bit bus.


In its turn, GeForce GTX 1070 comprises 1,920 streaming processors, 120 TMU and 64 ROP. The volume of the GDDR5 memory with a 256- bit bus equals to 8 GB.


Both novelties possess the factory overclocking. The GeForce GTX 1080 chip core base clock is raised from 1,607 MHz to 1,733 MHz, the augmented frequency — from 1,733 MHz to 1,873 MHz. The GeForce GTX 1070 version frequencies boosted from 1,506 MHz to 1,620 MHz and from 1,683 MHz to 1,822 MHz.


The cooling system includes three 100 mm fans. Backlighting is anticipated as well. Monitors can be connected through …
