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.

Tagged: external graphics, external gpu, CES 2017, CES, ASUS ROG, asus

ASUS today announced the XG Station Pro, a Thunderbolt 3-based external GPU enclosure tailored for both gamers and professionals. The XG Station Pro can accommodate full-size GPUs up to 2.5 slots wide, including large cards such as the ROG Strix 1080 Ti and Radeon RX Vega 64.

Featuring a "contemporary design with clean lines and subtle styling," the XG Station Pro has a footprint of 4.3-inches x 14.8-inches, thanks to ASUS's decision to use an external power supply. In order to provide enough juice for high-end graphics cards, ASUS is borrowing the power supply design from its GX800 gaming laptop, which puts out up to 330 watts.

The XG Station Pro's chassis, designed by case maker In Win, has a smooth dark gray finish with a black PCB and sleeved PCIe power cables. It features a soft white internal glow that can be controlled by ASUS's Aura software, including Aura Sync to synchronize lighting with your compatible ASUS and ROG graphics cards and laptops.

Inside the XG Station Pro, dual 120mm PWM fans provide exhaust out of the right side of the chassis. The fans automatically ramp down and even shut off below certain temperatures, but users can also manually control the fans with the ASUS GPU Tweak II application.

xgstationpro-standing.jpg

Around back, users will find an extra USB Type-C 3.1 Gen 2 port, which can supply up to 15 watts of power to compatible devices such as smartphones and external storage. Finally, ASUS notes that it includes the require Thunderbolt 3 cable in the box, something that many Thunderbolt-based devices seem to lack.

The ASUS XG Station Pro will launch later this month for $329 with support for both AMD and NVIDIA GPUs in Windows 10, and just AMD Vega-based GPUs in macOS Sierra and newer.

Specifications and Design

With all of the activity in both the GPU and CPU markets this year, it's hard to remember some of the launches in the first half of the year—including NVIDIA's GTX 1080 Ti. Maintaining the rank of fastest gaming GPU for the majority of the year, little has challenged NVIDIA's GP102-based offering, making it the defacto choice for high-end gamers.

Even though we've been giving a lot of attention to NVIDIA's new flagship TITAN V graphics card, the $3000 puts it out of the range of almost every gamer who doesn't have a day job involving deep learning.

Today, we're taking a look back to the (slightly) more reasonable GP102 and the one of the most premiere offerings to feature it, the ASUS ROG Strix GTX 1080 Ti.

Hardware Specifications

While the actual specifications of the GP102 GPU onboard the ASUS Strix GTX 1080 Ti hasn't changed at all, let's take a moment to refresh ourselves on where it sits in regards to the rest of the market.

If you'd like some additional details on the NVIDIA GTX 1080 Ti, or it's GP102 GPU, take a look at our review of the reference Founder's edition.

The GTX 1000 series of products from NVIDIA has marked a consolidation in ASUS's GPU offerings. Instead of having both Strix and Matrix products available, the Strix has supplanted everything to be the most premium option from ASUS for any given GPU, and the Strix GTX 1080 Ti doesn't disappoint.

IMG_5018.JPG

While it might not be the largest graphics card we've ever seen, the ASUS Strix GTX 1080 Ti is more massive in all dimensions compared to both the NVIDIA Founder's Edition card, as well as the EVGA ICX option we took a look at earlier this year. Compared to the Founder's Edition, the Strix GTX 1080 Ti is 1.23-in longer, 0.9-in taller, and takes up an extra PCIe slot in width.

How deep is your learning?

Recently, we've had some hands-on time with NVIDIA's new TITAN V graphics card. Equipped with the GV100 GPU, the TITAN V has shown us some impressive results in both gaming and GPGPU compute workloads.

However, one of the most interesting areas that NVIDIA has been touting for GV100 has been deep learning. With a 1.33x increase in single-precision FP32 compute over the Titan Xp, and the addition of specialized Tensor Cores for deep learning, the TITAN V is well positioned for deep learning workflows.

In mathematics, a tensor is a multi-dimensional array of numerical values with respect to a given basis. While we won't go deep into the math behind it, Tensors are a crucial data structure for deep learning applications.

07.jpg

NVIDIA's Tensor Cores aim to accelerate Tensor-based math by utilizing half-precision FP16 math in order to process both dimensions of a Tensor at the same time. The GV100 GPU contains 640 of these Tensor Cores to accelerate FP16 neural network training.

It's worth noting that these are not the first Tensor operation-specific hardware, with others such as Google developing hardware for these specific functions.

Looking Towards the Professionals

This is a multi-part story for the NVIDIA Titan V:

Earlier this week we dove into the new NVIDIA Titan V graphics card and looked at its performacne from a gaming perspective. Our conclusions were more or less what we expected - the card was on average ~20% faster than the Titan Xp and about ~80% faster than the GeForce GTX 1080. But with that $3000 price tag, the Titan V isn't going to win any enthusiasts over.

What the Titan V is meant for in reality is the compute space. Developers, coders, engineers, and professionals that use GPU hardware for research, for profit, or for both. In that case, $2999 for the Titan V is simply an investment that needs to show value in select workloads. And though $3000 is still a lot of money, keep in mind that the NVIDIA Quadro GP100, the most recent part with full-performance double precision compute from the Pascal chip, is still selling for well over $6000 today. 

IMG_5009.JPG

The Volta GV100 GPU offers 1:2 double precision performance, equating to 2560 FP64 cores. That is a HUGE leap over the GP102 GPU used on the Titan Xp that uses a 1:32 ratio, giving us just 120 FP64 cores equivalent.

SAPPHIRE Releases NITRO+ Radeon RX Vega (64 & 56)

Subject: Graphics Cards | December 15, 2017 - 09:00 AM |
Tagged: vega 64 liquid, vega 64, vega 56, Vega, sapphire, radeon, amd

SAPPHIRE has just launched a pair of custom cooled, factory overclocked, RX Vega-based graphics cards. As you might guess: the SAPPHIRE NITRO+ Radeon RX Vega 64 uses the Vega 64 chip with its 4096 stream processors, while the SAPPHIRE NITRO+ Radeon RX Vega 56 uses the Vega 56 chip and its 3584 stream processors. Both cards have 8GB of HBM2 memory (two stacks of 4GB). The cooler design uses three fans and vapor chambers, with separate heat pipes for the GPU+Memory (six pipes) and VRMs (two pipes).

It also has a back plate!

11275-00_VEGA64_Nitro_Plus_2DP2HDMI_C05.jpg

The clock rate is where it gets interesting. The NITRO+ RX Vega 64 will have a boost clock of 1611 MHz out-of-the-box. This is above the RX Vega 64 Air’s boost clock (1546 MHz) but below the RX Vega 64 Liquid’s boost clock (1677 MHz). The liquid-cooled Radeon RX Vega 64 still has the highest clocks, but this product sits almost exactly half-way between it (the liquid-cooled RX Vega 64) and the air-cooled RX Vega 64.

The NITRO+ Radeon RX Vega 56, with its 1572 MHz boost clock, is well above the stock RX Vega 56’s 1471 MHz boost clock, though. It’s a clear win.

As for enthusiast features, this card has quite a few ways to keep it cool. First, it will operate fanless until 56C. Second, the card accepts a 4-pin fan connector, which allows it to adjust the speed of two case fans based on the temperature readings from the card. I am a bit curious whether it’s better to let the GPU control the fans, or whether having them all attached to the same place allows them to work together more effectively. Either way, if you ran out of fan headers, then I’m guessing that this feature will be good for you anyway.

The SAPPHIRE NITRO+ Radeon RX Vega 64 and 56 are available now.

A preview of potential Volta gaming hardware

This is a multi-part story for the NVIDIA Titan V:

As a surprise to most of us in the media community, NVIDIA launched a new graphics card to the world, the TITAN V. No longer sporting the GeForce brand, NVIDIA has returned the Titan line of cards to where it began – clearly targeted at the world of developers and general purpose compute. And if that branding switch isn’t enough to drive that home, I’m guessing the $2999 price tag will be.

Today’s article is going to look at the TITAN V from the angle that is likely most interesting to the majority of our readers, that also happens to be the angle that NVIDIA is least interested in us discussing. Though targeted at machine learning and the like, there is little doubt in my mind that some crazy people will want to take on the $3000 price to see what kind of gaming power this card can provide. After all, this marks the first time that a Volta-based GPU from NVIDIA has shipped in a place a consumer can get their hands on it, and the first time it has shipped with display outputs. (That’s kind of important to build a PC around it…)

IMG_4999.JPG

From a scientific standpoint, we wanted to look at the Titan V for the same reasons we tested the AMD Vega Frontier Edition cards upon their launch: using it to estimate how future consumer-class cards will perform in gaming. And, just as we had to do then, we purchased this Titan V from NVIDIA.com with our own money. (If anyone wants to buy this from me to recoup the costs, please let me know! Ha!)

The Titan V is based on the GV100 GPU though with some tweaks that lower performance and capability slightly when compared to the Tesla-branded equivalent hardware. Though our add-in card iteration has the full 5120 CUDA cores enabled, the HBM2 memory bus is reduced from 4096-bit to 3072-bit and it has one of the four stacks on the package disabled. This also drops the memory capacity from 16GB to 12GB, and memory bandwidth to 652.8 GB/s.

Video: What does a $3000 GPU look like? NVIDIA TITAN V Unboxing and Teardown!

Subject: Graphics Cards | December 12, 2017 - 07:51 PM |
Tagged: nvidia, titan, titan v, Volta, video, teardown, unboxing

NVIDIA launched the new Titan V graphics card last week, a $2999 part targeted not at gamers (thankfully) but instead at developers of machine learning applications. Based on the GV100 GPU and 12GB of HBM2 memory, the Titan V is an incredibly powerful graphics card. We have every intention of looking at the gaming performance of this card as a "preview" of potential consumer Volta cards that may come out next year. (This is identical to our stance of testing the Vega Frontier Edition cards.)

But for now, enjoy this unboxing and teardown video that takes apart the card to get a good glimpse of that GV100 GPU.

A couple of quick interesting notes:

  • This implementation has 25% of the memory and ROPs disabled, giving us 12GB of HBM2, a 3072-bit bus, and 96 ROPs.
  • Clock speeds in our testing look to be much higher than the base AND boost ratings.
  • So far, even though the price takes this out of the gaming segment completely, we are impressed with some of the gaming results we have found.
  • The cooler might LOOK the same, but it definitely is heavier than the cooler and build for the Titan Xp.
  • Champagne. It's champagne colored.
  • Double precision performance is insanely good, spanking the Titan Xp and Vega so far in many tests.
  • More soon!
