After launching its shockingly fast (claimed) GEFORCE GTX 1080 and GTX 1070 graphics cards, NVIDIA posted specifications of the former. The two are based on NVIDIA’s swanky new 16 nm “GP104″ silicon, derived from its “Pascal” GPU architecture.
The GEFORCE GTX 1080 leads the pack, featuring four graphics processing clusters, holding 2,560 CUDA cores. The core runs at a scorching 1607 MHz, with a GPU Boost frequency of 1733 MHz. In one of its demos, NVIDIA overclocked this chip to over 2100 MHz, on its reference air cooling, and the GPU barely scraped 67 °C under stress. The GTX 1080 features a 256-bit wide GDDR5X memory interface, holding 8 GB of memory. The memory is clocked at 2500 MHz (10 GHz effective), working out to a memory bandwidth of 320 GB/s. That’s insane ! NVIDIA preditc that one 1080 GTX will count as 2x GTX 980s in SLI.
API support includes DirectX 12 (feature-level 12_1), OpenGL 4.5, and Vulkan. Display outputs include three DisplayPort 1.4 connectors, one HDMI 2.0b, and one dual-link DVI. The reference-design card is 10.5-inch long, and double-slot. It draws power from a single 8-pin PCIe power connector, and its typical board power is rated at 180W. With the GeForce “Pascal” family, instead of caving in to DirectX 12 native multi-GPU, NVIDIA developed its SLI technology further, with the new SLI HB (high-bandwidth) bridge standard. It’s essentially a 2-way bridge in which both SLI fingers of the card are used. This doubles bandwidth between the two cards, allowing higher display resolutions, and multi-display setups between high-resolution monitors. The GeForce GTX 1080 will be available from May 27, 2016, starting at US $599.
ANd regarding its second fastest GPU, the GEFORCE GTX 1070. Based on the same 16 nm GP104 silicon as the GTX 1080, the GTX 1070 features 8 GB of GDDR5 memory, and has 3 quarters the single precision performance (6.5 TFLOP/s vs. 9 TFLOP/s) of the GTX 1080. NVIDIA claims that the GTX 1070 is faster than the GTX TITAN X, making it the second fastest GPU in existence. Available on June 10, the GTX 1070 will be priced at US $379, with a “founder’s edition” (reference-design) card going for $449.
We are very exited about these new cards.
