An update from sweclockers.com has revealed the code name of the next-next-gen AMD Radeon R9 400 Series GPUs. It goes without saying that the naming is pretty much irrelevant at such an early stage. The revealed codename for the series is Arctic Islands and the actual GPU name could be of any island present there. There is currently zero information regarding the Radeon R9 400 Series apart from the fact it will be based on a 20nm or lower node (most probably 16/14nm FinFET).

Nvidia Pascalhttp://slo-tech.com/forum/t634624#crtaM-Powerhttp://slo-tech.com/forum/t634624#crtahttp://slo-tech.com/forum/t634624#crtaSun, 26 Jun 2016 00:20:41 +0200


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?:| ]]>
Raspberry Pihttp://slo-tech.com/forum/t508421#crtaTerohttp://slo-tech.com/forum/t508421#crtahttp://slo-tech.com/forum/t508421#crtaSun, 26 Jun 2016 00:00:17 +0200

Kaj je Raspberry Pi?

Raspberry Pi je zelo majhen in poceni računalnik (stane samo 35$) ki lahko počne kar veliko stvari kot vaš "pravi" pc(internet brskalnik, opneoffice aplkacija itd) Zaradi majhnosti in cene ga lahko uporabimo tudi namesto mikrokontrolerjev, routerjev in podobno. "Uradno" je namenjen izobraževalni sferi, oziroma šolam, da bi otroci dobili željo in voljo po programiranju.

Kako izgleda?
Skica:



Slika beta verzija(final verzija bo malo drugačna)



Kateri operacijski sistem na njem deluje in ali je to lahko windows?
Ne. R-pi iima ARM arhikteturo za kateraga windowsi niso namenjeni. (arm se recimo med drugim uporablja v mobilnih telefonih) Je pa super podprt Linux.
Na začetku bodo uradno podprte Fedora, Debian in Arch Linux.(ubuntu zaenkrat ni mogoče poganjat ker ubuntu ne podpira te starejše verzije arm-a) Teoretično bi na njem lahko poganjali Android, vendar je lahko problem premalo RAM-a.

Kakšne so specifikacije?
R-pi ima Broadcom SoC BCM 2835 čip v katerem je ARM1176JZF-S 700 MHz procesor, in grafični čip VideoCore IV. R-pi ima tudi 256MB rama. R-pi nima nobenega sata ali kakršnegakoli priključka za trdi disk(razen USB). Operacijski sistem in vse ostalo se naloži iz SD kartice. Ostali priključki so HDMI, RCA(video), stereo jack, 2 USB priključka in nekaj GPIO pinov in nekateri drugi lov-level priključke. Grafični čip je sposoben predvajat HD video v 1080p H.264.
V praksi je tale računalnik nekaj podobnega kot 300MHz Pentium 2, a z zelo boljšo grafiko( nekje podobna kot v xboxu prve generacije). Nažalost r-pi nima vga izhoda, tako da če bi ga radi priklopili na kak sterejši monitor potrebujete kakšen pretvornik.

Ali ima wifi, bluetooth...
Ne. Vendar glede na to da ima dva usb priključka(lahko seveda tudi več če priklopimo usb hub) lahko te zunanje naprave lepo priklopimo.

Kje in kdaj ga lahko kupim?
Uradni podatek je da se bo začel prodajat konec februarja, začetek marca.

Kako je z ohišjem in napajanjem?
Prve verzije bodo brez ohišja in brez napajalnika. R-pi ima za napajanje micro usb priključek tako da večinoma lahko uporabite kar polnilce ki jih imate za mobilne telefone, le pazit je treba da imajo dovolj moči. ]]>
