2:1 compression has been enhanced to be effective more often.
#Titan x pascal fp64 plus#
If the packed together result of reference values plus delta values is less than half the uncompressed storage size, then delta color compression succeeds and the data is stored at half size (2:1 compression). Pascal GPUs include a significantly enhanced delta color compression capability: If the deltas are small then only a few bits per pixel are needed. With delta color compression, the GPU calculates the differences between pixels in a block and stores the block as a set of reference pixels plus the delta values from the reference. One of the most important algorithms is delta color compression. Well, you can never have too much bandwidth so Nvidia applied some more tricks, color compression being one of them. The GPU’s compression pipeline has a number of different algorithms that intelligently determine the most efficient way to compress the data. The Titan X uses GDDR5X memory, the really good stuff at 10,000 MHz (effective), 12 GB and all on a 384-bit wise memory bus. With 12 GB graphics memory available for one GPU, the Titan X is very attractive for both modern and future games no matter what resolution you game at. For your reference here's a quick overview of some past generation high-end GeForce cards.
#Titan x pascal fp64 windows 10#
The latest revision of DX12 is a Windows 10 feature only, yet will bring in significant optimizations.
#Titan x pascal fp64 series#
The GeForce GTX 1000 series are DirectX 12 ready, in our testing we'll address some Async compute tests as well as Pascal now has Enhanced Async compute. As far as the memory specs of the GP102 GPU are concerned, these boards will feature a 384-bit memory bus connected to a nice 12 GB of GDDR5X video memory, AKA VRAM AKA framebuffer AKA graphics memory for the graphics card. The Titan X card will be released with a core clock frequency of 1.4 GHz with a Boost frequency that can run up to 1.5 GHz (and even higher depending on load and thermals). Each SM contains 128 CUDA cores, 256 KB of register file capacity, a 96 KB shared memory unit, 48 KB of total L1 cache storage, and eight texture units. Each GPC ships with a dedicated raster engine and 28 SMs. Don't let that confuse you, it is 128 shader units per SM.
Thus two out of two GPCs have been disabled. The NVIDIA Titan X however is not fully enabled. There are 28 active (SM) clusters for a fully enabled Pascal GP102 GPU. The GP102 PolyMorph Engine also includes a new Simultaneous Multi-Projection units. Each SM is paired with a PolyMorph Engine that handles vertex fetch, tessellation, viewport transformation, vertex attribute setup, and perspective correction. Pascal GPUs are composed of different configurations of Graphics Processing Clusters (GPCs), Streaming Multiprocessors (SMs), and memory controllers. Much like in the past designs you will see pre-modelled SMX clusters that hold what is 2圆4 shader processors per cluster. The GPU is based on DX12 compatible architecture called Pascal.
