NVIDIA Tegra K1 Benchmarks Spotted

The Chinese tech site, Evolife, acquired a few benchmarks for the Tegra K1. We do not know exactly where they got the system from, but we know that it has 4GB of RAM and 12 GB of storage. Of course, this is the version with four ARM Cortex-A15 cores (not the upcoming, 64-bit version based on Project Denver). On 3DMark Ice Storm Unlimited, it was capable of 25737 points, full system.

You might remember that our tests with an Intel Core i5-3317U (Ivy Bridge), back in September, achieved a score of 25630 on 3DMark Ice Storm. Of course, that was using the built-in Intel HD 4000 graphics, not a discrete solution, but it still kept up for gaming. This makes sense, though. Intel HD 4000 (GT2) graphics has a theoretical performance of 332.8 GFLOPs, while the Tegra K1 is rated at 364.8 GFLOPs. Earlier, we said that its theoretical performance is roughly on par with the GeForce 9600 GT, although the Tegra K1 supports newer APIs.

Of course, Intel has released better solutions with Haswell. Benchmarks show that Iris Pro is able to play Battlefield 4 on High settings, at 720p, with about 30FPS. The HD 4000 only gets about 12 FPS with the same configuration (and ~30 FPS on Low). This is not to compare Intel to NVIDIA's mobile part, but rather compare Tegra K1 to modern, mainstream laptops and desktops. It is getting fairly close, especially with the first wave of K1 tablets entering at the mid-$200 USD MSRP in China.

As a final note...

There was a time where Tim Sweeney, CEO of Epic Games, said that the difference between high-end and low-end PCs "is something like 100x". Scaling a single game between the two performance tiers would be next-to impossible. He noted that ten years earlier, that factor was more "10x".

Now, an original GeForce Titan is about 12x faster than the Tegra K1 and they support the same feature set. In other words, it is easier to develop a game for the PC and high-end tablet than it was to develop an PC game for high-end and low-end machines, back in 2008. PC Gaming is, once again, getting healthier.

AMD Radeon R9 Prices Have Leveled Out, R9 280 Drops to $249

Just the other day AMD sent out an email to the media to discuss the current pricing situation of the Radeon R9 series of graphics cards. This email started with the following statement.

You’ve seen many articles, discussions online about the AMD Radeon™ R9 lineup – especially chatter about pricing and availability. As we’ve talked about it before, the demand for the R9 lineup has been nothing but astonishing, and went well beyond our most optimistic expectations. That created a situation where gamers weren’t able to purchase their desired R9 graphics card.

Radeon_R9Fan_WaterCooler_Product_Shot_Birdseye_5in300dpi_4c.jpg

Clearly AMD would not bring up the subject if the current situation was BAD news so guess what? All seems to be back normal (or expected) in terms of AMD Radeon R9 pricing and card availability. Take a look at the table below to get an idea of where Radeon's currently stand.

  Amazon.com Newegg.com
Radeon R9 295X2 $1524 $1499
Radeon R9 290X  $549 $529
Radeon R9 290 $379 $399
Radeon R9 280X $289 $299
Radeon R9 280 $249 $249
Radeon R9 270X $199 $189
Radeon R9 270 $169 $179

There is one price change that differs from the products' launch - the SEP of the Radeon R9 280 has dropped from $279 to $249. Nothing dramatic but a nice change.

Maybe most interesting is this line from the AMD email.

Now that product is available and at suggested pricing, these prices will remain stable. No more madness like you saw in Q1.

That emphasis is AMD's. I'm not quite sure how the company thinks they can keep a tight control on pricing now if it wasn't able to do so before, but more than likely, with the rush for coin mining hardware somewhat dying off, the prediction will hold true. (As a side note, there appears to be some discounts to be found on used Radeon hardware these days...)

AMD-Never-Settle-Forever-2014-01.jpg

Of course the AMD bundling promotion known as Never Settle Forever is still going strong with these new prices as well. Scott wrote up a story detailing this latest incarnation of the promotion and he and I both agree that while free is always good great, the age of most of the titles in the program is a bit of a problem. But AMD did note in this email that they have "lined up a few brand new games to add to this promotion, and they'll [sic] be sharing more info with you in the next few weeks!"

Xiaomi MiPad Tablet is Tegra K1 Powered

Subject: General Tech, Graphics Cards, Processors, Mobile | May 15, 2014 - 02:02 PM |
Tagged: nvidia, xaiomi, mipad, tegra k1

Tegra K1 is NVIDIA's new mobile processor and this first to implement the Kepler graphics architecture. In other words, it has all of the same graphics functionality as a desktop GPU with 364 GigaFLOPs of performance (a little faster than a GeForce 9600 GT). This is quite fast for a mobile product. For instance, that amount of graphics performance could max out Unreal Tournament 3 to 2560x1600 and run Crysis at 720p. Being Kepler, it supports OpenGL 4.4, OpenGL ES 3.1, DirectX 11 and 12, and GPU compute languages.

Xiaomi is launching their MiPad in Beijing, today, with an 8-inch 2048x1536 screen and the Tegra K1. They will be available in June (for China) starting at $240 USD for the 16GB version and going up to $270 for the 64GB version. Each version has 2GB of RAM, an 8MP rear-facing camera, and a 5MP front camera.

Now, we wait and see if any Tegra K1 devices come to North America and Europe - especially at that price point.

NVIDIA Titan Z Missed Its Release Date

Subject: General Tech, Graphics Cards | May 12, 2014 - 05:00 PM |
Tagged: titan z, nvidia, gtx titan z, geforce

To a crowd of press and developers at their GTC summit, NVIDIA announced the GeForce GTX Titan Z add-in board (AIB). Each of the two, fully unlocked, GK110 GPUs would each have access to 6GB of GDDR5 memory (12GB total). The card was expected to be available on May 8th but has yet to surface. As NVIDIA has yet to comment on the situation, many question whether it ever will.

nvidia-titan-z-where.png

And then we get what we think are leaked benchmarks (note: two pictures).

One concern about the Titan Z was its rated 8 TeraFLOPs of compute performance. This is a fairly sizable reduction from the theoretical maximum of 10.24 TeraFLOPs of two Titan Black processors and even less than two first-generation Titans (9 TeraFLOPs combined). We expected that this is due to reduced clock rates. What we did not expect is for benchmarks to show the GPUs boost way above those advertised levels, and even beyond the advertised boost clocks of the Titan Black and the 780 Ti. The card was seen pushing 1058 MHz in some sections, which leads to a theoretical compute performance of 12.2 TeraFLOPs (6.1 TeraFLOPs per GPU) in single precision. That is a lot.

These benchmarks also show that NVIDIA has a slight lead over AMD's R9 295X2 in many games, except Battlefield 4 and Sleeping Dogs (plus 3DMark and Unigine). Of course, these benchmarks measure the software reported frame rate and frame times and those may or may not be indicative of actual performance. While I would say that the Titan Z appears to have a slight performance lead over the R9 295X2, although a solid argument for an AMD performance win exists, it does so double the cost (at its expected $3000 USD price point). That is not up for debate.

Whichever card is faster, AMD's is half the price and available for purchase right now.

So, until NVIDIA says anything, the Titan Z is in limbo. I am sure there exists CUDA developers who await its arrival. Personally, I would just get three Titan Blacks since you are going to need to manually schedule your workloads across multiple processors anyway (or 780 Tis if 32-bit arithmetic is enough precision). That is, of course, unless you cannot physically fit enough GeForce Titan Blacks in your motherboard and, as such, you require two GK110 chips per AIB (but not enough to bother writing a cluster scheduling application).

NVIDIA GTX 780 Ti on Thunderbolt 2 by DIYers

Tagged: Thunderbolt 2, thunderbolt, nvidia, GeForce GTX 780 Ti

Externally-attached GPUs have been a topic for many years now. Numerous companies have tried, including AMD and Lucid, but no solution has ever been a widely known and available product. Even as interfaces increase in bandwidth and compatibility with internal buses, it has never been something that a laptop salesperson could suggest to users who want to dock into a high-performance station at home. At best, we are seeing it in weird "coin mining" racks to hang way more GPUs above a system than could physically mount on the motherboard.

Apparently that has not stopped the DIY community, according to chatter on Tech Inferno forums. While the above video does not really show the monitor, MacBook Pro, and GPU enclosure at the same time, let alone all wired together and on, it seems reasonable enough. The video claims to give the MacBook Pro (running Windows 8.1) access to a GeForce GTX 780 Ti with fairly high performance, despite the reduced bandwidth. Quite cool.

Check out the forum post for a few more details.

PowerColor Teasing Dual GPU Graphics Card With Massive Air Cooler

Subject: Graphics Cards | May 6, 2014 - 12:36 AM |
Tagged: r9 295x2, powercolor, hawaii, dual gpu, devil 13

PowerColor has been teasing a new graphics card on its Facebook page. The photos show a macro shot of the Devil 13 logo along with captions hitting at the new card being a dual GPU monster including one caption referring the upcoming Devil 13 as a "dual beast."

PowerColor's previous Devil 13 branded graphics card was the Radeon HD 7990 Devil 13 which contained two HD 7970 "Tahiti" GPUs on one PCB. Coincidentally, AMD recently launched a new dual GPU reference design based around two R9 290x "Hawaii" GPUs called the R9 295x2. It is still rumor and speculation at this point, but the timing and leaked photos seem to point squarely at the upcoming Devil 13 card being the first air cooled custom R9 295x2!

Adding credence to the rumors, leaked photos have appeared online with a PCB backplate that appears to match the backplate shown in the official teaser photo. The leaked photos show an absolutely beastly triple slot graphics card that places two GPUs in CrossFire on a single custom PCB powered by four 8-pin PCI-E power connectors and cooled by a gargantuan HSF comprised of an aluminum fin stack and multiple large diameter copper heatpipes along with three fans. The cooler and PCB are reinforced with brackets and a metal backplate to help keep the air cooler in pace and the PCB from bending.

If the rumors hold true, PowerColor will be unveiling the first air cooled dual GPU R9 295X2 graphics card which is an impressive feat of engineering! Using four 8-pin PCI-E power connectors definitely suggests that aftermarket overclocking is encouraged and supported even if PowerColor does not end up factory overclocking their dual GPU beast.

For reference, the stock AMD R9 295X2 features two full Hawaii GPUs with 5,632 stream processors clocked at up to 1018 MHz interfaced with 8GB of total GDDR5 memory over a 512-bit bus (each GPU has 4GB of memory and a 512-bit bus). AMD rates this configuration at 11.5 TFLOPS of single precision performance. The reference R9 295X2 has a 500W TDP and uses two 8-pin PCI-E power connectors.

Please excuse me while I wipe the drool off of my keyboard...

Stay tuned to PC Perspective for more details on the mysterious dual GPU Devil 13 from PowerColor!

In the meantime, check out our full review of the R9 295X2 (and the Hawaii architecture) and what happens when you put two R9 295X2s in Quad CrossFire into a single system for 4K gaming goodness!

GeForce Experience 2.0.1 Update Released

Subject: General Tech, Graphics Cards | May 5, 2014 - 02:03 PM |
Tagged: nvidia, geforce experience, shield

NVIDIA has released version 2.0.1 of GeForce Experience. This update does not bring many new features, hence why it is a third-level increment to the version number, but is probably worthwhile to download regardless. Its headlining feature is security enhancements with OpenSSL under remote GameStream on SHIELD. The update also claims to improve streaming quality and reduce audio latency.

nvidia-shield-gamestream-02.jpg

While they do not seem to elaborate, I assume this is meant to fix Heartbleed, which is an exploit that allows an attacker to receive a small snapshot of active memory. If that is that case, it is unclear whether the SHIELD, the host PC during a game session, or both endpoints are affected.

The new GeForce Experience is available at the NVIDIA website. If it is running, it will also ask you to update it, of course.

Asus Launches GTX TITAN Z Dual GK110 Graphics Card

Subject: Graphics Cards | May 1, 2014 - 10:29 PM |
Tagged: titan z, nvidia, gpgpu, gk110, dual gpu, asus

NVIDIA unveiled the GeForce GTX TITAN Z at the GPU Technology Conference last month, and the cards will be for sale soon from various partners. ASUS will be one of the first AIB partners to offer a reference TITAN-Z.

The ASUS GTX TITAN Z pairs two full GK110-based GPUs with 12GB of GDDR5 memory. The graphics card houses a total of 5,760 CUDA cores, 480 texture manipulation units (TMUs), and 96 ROPs. Each GK110 GPU interfaces with 6GB of GDDR5 memory via a 384-bit bus. ASUS is using reference clockspeeds with this card, which means 705 MHz base and up to 876 MHz GPU Boost for the GPUs and 7.0 GHz for the memory.

For comparison, the dual-GPU TITAN Z is effectively two GTX TITAN Black cards on a single PCB. However, the TITAN Black runs at 889 MHz base and up to 980 MHz GPU Boost. A hybrid water cooling solution may have allowed NVIDIA to maintain the clockspeed advantage, but doing so would compromise the only advantage the TITAN Z has over using two (much cheaper) TITAN Blacks in a workstation or server: card density. A small hit in clockspeed will be a manageable sacrifice for the target market, I believe.

The ASUS GTX TITAN Z has a 375W TDP and is powered by two 8-pin PCI-E power connectors. The new flagship dual GPU NVIDIA card has an MSRP of $3,000 and should be available in early May.

AMD Mantle Private Beta Announced

Subject: General Tech, Graphics Cards | May 1, 2014 - 05:00 AM |
Tagged: Mantle, amd

As our readers are well aware, Mantle is available for use with a few games. Its compatibility begun with the beta Catalyst 14.1 driver and an update for Battlefield 4. AMD was quite upfront about the technology, even granting a brief interview with Guennadi Riguer, Chief Architect of the API to fill in a few of the gaps left from their various keynote speeches.

AMD_Mantle_Logo.png

What is under lock and key, however, is the actual software development kit (SDK). AMD claimed that it was too immature for the public. It was developed in partnership with DICE, Oxide Games, and other, established developers to fine-tune its shape, all the while making it more robust. That's fine. They have a development plan. There is nothing wrong with that. Today, while the SDK is still not public and sealed by non-disclosure agreement, AMD is accepting applications from developers who are requesting to enter the program.

If you want to develop a Mantle application or game, follow the instructions at their website for AMD to consider you. They consider it stable, performant, and functional enough for "a broader audience in the developer community".

AMD cites 40 developers already registered, up from seven (DICE, Crytek, Oxide, etc.).

If you are not a developer, then this news really did not mean too much to you -- except that progress is being made.
