Nvidia’s next-generation graphics processors are code-named “Pascal”. Based on the company’s roadmap that it demonstrated back in March, Pascal GPUs are due sometime in 2016. Next-generation graphics chips from Nvidia will support stacked high-bandwidth dynamic random access memory (DRAM) (SK Hynix’s high-bandwidth memory (HBM) or Micron’s hybrid memory cube (HMC)), unified memory addressing for CPU and GPU, NVLink interconnection for high-performance computing platforms as well as new graphics, compute and multimedia features that will be a part of DirectX 12, OpenGL 5.0 and other forthcoming application programming interfaces.

In 2016 displays with ultra-high-definition (UHD) resolutions like 4K (3840*2160, 4096*2160) or 5K (5120*2160) will get much more popular than they are today. Therefore, dramatically improved graphics processing horsepower of Pascal GPUs as well as extreme bandwidth provided by stacked HMC or HBM DRAM devices (we are talking about 1TB/s – 2TB/s bandwidth here) will be appreciated by the market.

What is Pascal?
Just as the Volta GPU was expected to, Pascal will have “3D stacked memory”—memory chips stacked one on top of the other and joined by circuitry, resulting in graphics cards that can access up to 1 terabyte per second (TBs) of bandwidth. The 1TB/s threshold will be achieved by stacking memory on top of the GPU itself, with a silica substrate between them, and then cutting a hole through the silicon to connect each layer. Nvidia’s current GPUs can access only 288GB/s; upcoming Pascal graphics cards, then, will be about 3.5 times faster.
According to Nvidia’s CEO, Jen Hsun-Huang, 1TB/s is fast enough to move “all of the data from a full Blu-Ray disc through the chip in 1/50th of a second.” It should be noted, though, that manufacturing GPUs with a terabyte of DRAM on them would make for some rather expensive graphics cards. Nvidia says that how much memory the Pascal cards will actually contain will come down to cost. Also, one must consider how much bandwidth are graphics card buyers willing to shell out for?

Leta 2016 pride Pascal in leta 2017 Volta. Če prav razumem bo Pascal za splošno rabo se pravi za nas Volta pa bolj za super računalnike?:| ]]>
USB tv/radio tuner in razširitev radijskih frekvenc, 26 Sep 2016 16:21:47 +0200 Par dni nazaj sem dobil ta tuner iz Singapurja, za borih 6,6EUR.
Najprej sem ga seveda preizkusil kot tv tuner, s priloženim Presto software-om. Deluje! Sicer je antena taka mini, tako da znotraj hiše težko kaj ujame, če pa že, samo en MUX. Na okenski polici zunaj pa oba slovenska MUX-a in s tem 11 oz. 14 tv programov.
Antena je vsekakor bolj tko, ampak za ta denar je čisto vredu. Tudi daljinec dela.
Ali se je kdo igral s programom RTL-SDR? Mi je uspelo naložiti driver in RTL-SDR, ampak nekako nimam pojma še kako in kaj. Cel kup šumenja :)

AMD Vega 10 / Greenland Flagship HBM2 GPU Launching In 2017

AMD Vega 10 GPU Features HBM2 – High-Performance Graphics Cards To Replace Fury Series Next Year
AMD’s goal with Vega 10 would be to replace their Fiji based Fury series with high-performance offerings that feature the second generation High-Bandwidth memory solution. The Vega series of GPUs are based on brand new technology and architecture designs. You may call it a step better than Polaris which itself is a 2.8x leap on AMD’s older 28nm products. Vega is going to deliver better performance per watt than Polaris due to a efficient memory architecture and a fine tuned 14nm FinFET process.

We have little details regarding Vega 10 at the moment but previous leaks suggest that the will feature 4096 stream processors. These are not the current generation stream processors but utilize the advancements made in the IP v9.0 generation of graphics SOCs under development by AMD. It is also noted that this chip is the “Leading Chip” of the first graphic IP v9.0 chip generation. We can expect to see a liquid cooled design and a new dual GPU offering under the Vega family when it launches in 2017. ]]>
nvidia gtx 980 ti strix + i7 2600, 25 Sep 2016 19:50:59 +0200
Kolega v glavnem igra Microsoftov simulator letenja. V želji, da bi lahko igral na malo boljših nastavitvah je kupil gafično nvidia gtx 980 ti strix. Izboljšanje ni tako, kot je pričakoval oziroma ga skoraj ni. Je mogoče kriv procesor (ozko grlo)? Ima pa še nekih 16GB rama. Jaz mu lahko rečem, da je to možno, ma nisem tak strokovnjak, da bi lahko to trdil z gotovostjo. ]]>
