[H]ard|OCP are comparing AMD and NVIDIA's exhibitionist software to see which offers streamers the best experience.  The two applications are superficially similar but they both offer different features and performance, not to mention only supporting their own hardware.  From a performance standpoint, NVIDIA's ShadowPlay is slightly ahead in efficiency but not in any meaningful way, you would not be able to discern between the two in a blind test.  When you look at features, AMD's ReLive is the clear winner.  You can set your bitrate between 1-100Mbps at every resolution, from 360p to 2160p while NVIDIA maxes out at 50Mbps at any resolution and only supports up to 1440p.  There are several other features AMD included which surpass NVIDIA's offerings, read about them all here.

CES 2018: NVIDIA Opens Up GeForce NOW Beta To PC Gamers

Subject: General Tech, Graphics Cards | January 8, 2018 - 11:35 PM |
Tagged: pc game streaming, nvidia, geforce now, game streaming, cloud gaming, CES 2018, CES

NVIDIA is opening up its Geforce NOW cloud gaming service to PC gamers who will join Mac users (who got access last year) in the free beta. The service uses GeForce GTX graphics cards and high-powered servers to store, play, and stream games at high settings and stream the output over the internet back to gamers of any desktop or laptop old or new (so long as you have at least a 25Mbps internet connection and can meet the basic requirements to run the Geforce NOW application of course - see below). Currently, NVIDIA supports over 160 games that can be installed on its virtual GeForce NOW gaming PCs and a select number of optimized titles can even be played at 120 FPS for a smoother gaming experience that is closer to playing locally (allegedly).

GeForce NOW is a bring your own games service in the sense that you install the Geforce NOW app on your local machine and validate the games you have purchased and have the rights to play on Steam and Ubisoft's Uplay PC stores. You are then able to install the games on the cloud-based Geforce NOW machines. The game installations reportedly take around 30 seconds with game patching, configurations, and driver updates being handled by NVIDIA's Geforce NOW platform. Gamers will be glad to know that the infrastructure further supports syncing with the games' respective stores and save games, achievements, and settings are synched allowing potentially seamless transitions between local and remote play sessions. 

You can find a list of currently supported games here, but some highlights include some oldies and newer titles including: Borderlands 2, Bioshock Remastered, various Call of Duty titles, League of Legends, Left 4 Dead 2, Kerbal Space Program, Just Cause 3, StarCraft II, Resident Evil 7, KOTOR, Tomb Raider, Metal Gear Solid, Dirt 4 (just for Josh), Project Cars 2, Fallout 4, XCOM 2 (a personal favorite), PUBG, WoW, Civilization VI, and more.

While many of the titles may need to be tweaked to get the best performance, some games have been certified and optimized by NVIDIA to come pre-configured with the best graphics settings for optimum performance including running them at maximum settings at 1920 x 1080 and 120 Hz.

If you are interested in the cloud-based game streaming service, you can sign up for the GeForce NOW beta here and join the waiting list! According to AnandTech, users will need a Windows 7 (or OS X equivalent) PC with at least a Core i3 clocked at 3.1 GHz with 4GB of RAM and a DirectX 9 GPU (AMD HD 3000 series / NVIDIA 600 Series / Intel HD 2000 series) or better. Beta users are limited to 4 hours per gaming session. There is no word on when the paid Geforce NOW tiers will resume or what the pricing for the rented virtual gaming desktops will be.

I signed up (not sure I'll get in though, maybe they need someone to test with old hardware hah) and am interested to try it as their past streaming attempts (e.g. to the Shield Portable) seemed to work pretty well for what it was (something streamed over the internet).

Hopefully they have managed to make it better and quicker to respond to inputs. Have you managed to get access, and if so what are your thoughts? Is GeForce NOW the way its meant to be played? It would be cool to see them add Space Engineers and Sins of a Solar Empire: Rebellion as while me and my brother have fun playing them, they are quite demanding resource wise especially Space Engineers post planets update!

Gaming in isolation, complete Meltdown or not?

Subject: Processors | January 8, 2018 - 07:24 PM |
Tagged: meltdown, security, linux, nvidia

Thanks to a wee tech conference going on, performing a wide gamut of testing of the effect of the Meltdown patch is taking some time.  Al has performed benchmarks focusing on the performance impact the patch has on your storage subsystem, which proved to be very minimal.  Phoronix are continuing their Linux testing, the latest of which focuses on the impact the patch has on NVIDIA GPUs, specifically the GTX 1060 and GTX 1080 Ti.  The performance delta they see falls within measurement error levels; in other words there is no measurable impact after the patch was installed.  For now it seems the most impact this patch has is for scientific applications and hosting providers which use select high I/O workloads and large amounts of virtual machines.  For now the cure to Meltdown is nowhere near as bad as what it protects against for most users ... pity the same cannot be said for Spectre.

"Earlier this week when news was still emerging on the "Intel CPU bug" now known as Spectre and Meltdown I ran some Radeon gaming tests with the preliminary Linux kernel patches providing Kernel Page Table Isolation (KPTI) support. Contrary to the hysteria, the gaming performance was minimally impacted with those open-source Radeon driver tests while today are some tests using the latest NVIDIA driver paired with a KPTI-enabled kernel."

CES 2018: ASUS ROG Strix GL12 Gaming Desktop Announced

Subject: Systems | January 8, 2018 - 09:00 AM |
Tagged: CES, ROG, nvidia, Intel, GTX 1080, geforce, coffee lake, asus, CES 2018

ASUS has just announced a high-end gaming desktop: the ROG Strix GL12. It looks like it will be a standard mid-tower form factor with a highly stylized design and, of course, RGB lights. They will pair with Aura Sync, so you make your case match your keyboard and pretty much whatever else you have from ASUS with RGB lights in it.

The main selling feature of the system, however, is the factory-overclocked Coffee Lake CPU – up to six cores at 4.8 GHz. You can also pair this with an NVIDIA GTX 1080. At first, I found it odd that they didn’t go up to the GTX 1080 Ti given the rest of the system, although I guess they would need to produce stock ahead of time, and it would be risky to have too many enthusiast parts sitting in a warehouse. They don’t state the maximum configurable RAM, but Coffee Lake maxes out at 64 GB so we know that it won’t be more than that. It all depends on whether ASUS wants to make a 32 GB or a 64 GB SKU.

The ASUS ROG Strix GL12 gaming desktop will launch in April. Pricing TBA.

CES 2018: NVIDIA announces Big Format Gaming Display initiative with 65-in G-SYNC

Subject: Graphics Cards, Displays | January 8, 2018 - 12:30 AM |
Tagged: SHIELD TV, nvidia, hp, hdr, g-sync, DCI-P3, bgfd, asus, android tv, acer

Although their Keynote presentation tonight at CES is all about automotive technology, that hasn't stopped NVIDIA from providing us with a few gaming-related announcements this week. The most interesting of which is what NVIDIA is calling "Big Format Gaming Displays" or BFGDs (get it?!).

Along with partners ASUS, Acer, and HP, NVIDIA has developed what seems to be the ultimate living room display solution for gamers.

Based on an HDR-enabled 65" 4K 120Hz panel, these displays integrate both NVIDIA G-SYNC variable refresh rate technology for smooth gameplay, as well as a built-in NVIDIA SHIELD TV set-top box.

In addition to G-SYNC technology, these displays will also feature a full direct-array backlight capable of a peak luminance of 1000-nits and conform to the DCI-P3 color gamut, both necessary features for a quality HDR experience. These specifications put the BFGDs in line with the current 4K HDR TVs on the market.

Unlike traditional televisions, these BFGDs are expected to have very low input latencies, a significant advantage for both PC and console gamers.

Integration of the SHIELD TV means that these displays will be more than just an extremely large PC monitor, but rather capable of replacing the TV in your living room. The Android TV operating system means you will get access to a lot of the most popular streaming video applications, as well as features like Google Assistant and NVIDIA GameStream.

Personally, I am excited at the idea of what is essentially a 65" TV, but optimized for things like low input latency. The current crop of high-end TVs on the market cater very little to gamers, with game modes that don't turn off all of the image processing effects and still have significant latency.

It's also interesting to see companies like ASUS, Acer, and HP who are well known in the PC display market essentially entering the TV market with these BFGD products.

Stay tuned as for eyes-on impression of the BFGD displays as part of our CES 2018 coverage!

Update: ASUS has officially announced their BFGD offering, the aptly named PG65 (pictured below). We have a meeting with ASUS this week, and we hope to get a look at this upcoming product!

NVIDIA addresses Spectre vulnerabilities

Subject: General Tech, Graphics Cards | January 5, 2018 - 02:59 PM |
Tagged: meltdown, spectre, geforce, quadro, NVS, nvidia, tesla, security

If you were wondering if NVIDIA products are vulnerable to some of the latest security threats, the answer is yes.  Your Shield device or GPU is not vulnerable to CVE-2017-5754, aka Meltdown, however the two variants of Spectre could theoretically be used to infect you. 

  • Variant 1 (CVE-2017-5753): Mitigations are provided with the security update included in this bulletin. NVIDIA expects to work together with its ecosystem partners on future updates to further strengthen mitigations.

  • Variant 2 (CVE-2017-5715): Mitigations are provided with the security update included in this bulletin. NVIDIA expects to work together with its ecosystem partners on future updates to further strengthen mitigations.

  • Variant 3 (CVE-2017-5754): At this time, NVIDIA has no reason to believe that Shield TV/tablet is vulnerable to this variant.

The Android based Shield tablet should be updated to Shield Experience 5.4, which should arrive before the end of the month.  Your Shield TV, should you actually still have a working on will receive Shield Experience 6.3 along the same time frame.

The GPU is a little more complex as there are several product lines and OSes which need to be dealt with.  There should be a new GeForce driver appearing early next week for gaming GPUs, with HPC cards receiving updates on the dates you can see below.

There is no reason to expect Radeon and Vega GPUs to suffer from these issues at this time.  Intel could learn a bit from NVIDIA's response, which has been very quick and includes ther older hardware.

AMD, a little too far ahead of the curve again?

Subject: General Tech | December 27, 2017 - 11:42 AM |
Tagged: nvidia, Intel, HBM2, deep learning

AMD has never been afraid to try new things, from hitting 1GHz first, to creating a true multicore processor, most recently adopting HBM and HBM2 into their graphics cards.  That move contributed to some of their recent difficulties with the current generation of GPUs; HBM is more expensive to produce and more of a challenge to implement.  While they were the first to implement HBM, it is NVIDIA and Intel which are benefiting from AMD's experimental nature.  Their new generation of HPC solutions, the Tesla P100, Quadro GP 100 and Lake Crest all use HBM2 and benefit from the experience Hynix, Samsung and TSMC gained fabbing the first generation.  Vega products offer slightly less memory bandwidth as well as lagging behind in overall performance, a drawback to being first.

On a positive note, AMD have now had more experience designing chips which make use of HBM and this could offer a new hope for the next generation of cards, both gaming and HPC flavours.  DigiTimes briefly covers the two processes manufacturers use in the production of HBM here.

_id1460366655_343178_1.jpg

"However, Intel's release of its deep-learning chip, Lake Crest, which came following its acquisition of Nervana, has come with HMB2. This indicates that HBM-based architecture will be the main development direction of memory solutions for HPC solutions by GPU vendors."
