$400 is a tempting number, much less expensive than the $650 price tag on the GTX 780 and right in line with the existing GTX670 as well as AMD's HD7970.  You will probably not see many at that price, $450 is more likely as there will be very few reference cards released, all manufacturers will be putting there own spins on the design of these cards, which brings the price in line with the GTX680.  Performance wise these cards outpace the two current single GPU flagship cards, not by enough to make it worth upgrading from a 7970 or 680 but certainly enough to attract owners of previous generation cards.  [H]ard|OCP reviewed MSI's Lightning model, with dual fans, an overclock of 104MHz on the base clock and 117MHz boost, plus a completely unlocked BIOS for even more tweaking choices.

If you want to see how well it fares on our new Frame Rating metric you will have to read Ryan's full review here.

GK104 gets cheaper and faster

A week ago today we posted our review of the GeForce GTX 780, NVIDIA's attempt to split the difference between the GTX 680 and the GTX Titan graphics cards in terms of performance and pricing.  Today NVIDIA launches the GeForce GTX 770 that, even though it has a fancy new name, is a card and a GPU that you are very familiar with.

The NVIDIA GK104 GPU Diagram

Based on GK104, the same GPU that powers the GTX 680 (released in March 2012), GTX 670 and the GTX 690 (though in a pair), the new GeForce GTX 770 has very few changes from the previous models that are really worth noting.  NVIDIA has updated the GPU Boost technology to 2.0 (more granular, better controls in software) but the real changes come in the clocks speeds.

specs2.png

The GTX 770 is still built around 4 GPCs and 8 SMXs for a grand total of 1536 CUDA cores, 128 texture units and 32 ROPs.  The clock speeds have increased from 1006 MHz base clock and 1058 MHz Boost up to 1046 MHz base and 1085 MHz Boost.  That is a pretty minor speed bump in reality, an increase of just 4% or so over the previous clock speeds. 

NVIDIA did bump up the GDDR5 memory speed considerably though, going from 6.0 Gbps to 7.0 Gbps, or 1750 MHz.  The memory bus width remains 256-bits wide but the total memory bandwidth has jumped up to 224.3 GB/s.

Maybe the best change for PC gamers is the new starting MSRP for the GeForce GTX 770 at $399 - a full $50-60 less than the GTX 680 was selling for as of yesterday.  If you happened to pick up a GTX 680 recently, you are going to want to look into your return options as this will surely annoying the crap out of you.

If you want more information on the architecture design of the GK104 GPU, check out our initial article on the chips release from last year.  Otherwise, with those few specification changes out of the way, let's move on to some interesting information.

The NVIDIA GeForce GTX 770 2GB Reference Card

Tired of this design yet?  If so, you'll want to look into some of the non-reference options I'll show you on the next page from other vendors, but I for one am still taken with the design of these cards.  You will find a handful of vendors offering up re-branded GTX 770 options at the outset of release but most will have their own SKUs to showcase.

Trimming the TITAN; NVIDIA's GTX 780

Subject: Graphics Cards | May 24, 2013 - 03:10 PM |
Tagged: nvidia, gtx 780, gk110, geforce

With 768 more CUDA Cores than the 680 but 384 less than the TITAN the 780 offers improvements over the previous generation and will be available for about $350 less than the TITAN.  As you can see in [H]ard|OCP's testing it does outperform the 680 and 7970 but not by a huge margin which hurts the price to performance ratio and makes it more attractive for 680 owners to pick up a second card for SLI.  AMD owners with previous generation cards and deep pockets might be tempted to pick up a pair of these cards as they show very good frame rating results in Ryan's review.

H_780.jpg

"NVIDIA's new GeForce GTX 780 video card has finally been unveiled. We review the GTX 780 with real world gaming with the most intense 3D games, including Metro: Last Light. If the GTX TITAN had you excited but was a bit out of your price range, the GTX 780 should hold your excitement while being a lot less expensive."

GK110 Gets a Lower Price Point

If you want to ask us some questions about the GTX 780 or our review, join us for a LIVE STREAM at 2pm EDT / 11am PDT on our LIVE page.

When NVIDIA released the GeForce GTX Titan in February there was a kind of collective gasp across the enthusiast base.  Half of that intake of air was from people amazed at the performance they were seeing on a single GPU graphics cards powered by the GK110 chip.  The other half was from people aghast of the $1000 price point that NVIDIA launched it at.  The GTX Titan was the fastest single GPU card in the world, without any debate, but with it came a cost we hadn't seen in some time.  Even with the debate between it, the GTX 690 and the HD 7990, the Titan was likely my favorite GPU, cost no concerns.

IMG_9863.JPG

Today we see the extension of the GK110, by cutting it back some, and releasing a new card.  The GeForce GTX 780 3GB is based on the same chip as the GTX Titan but with additional SMX units disabled, a lower CUDA core count and less memory.  But as you'll soon see, the performance delta between it and the GTX 680 and Radeon HD 7970 GHz is pretty impressive.  The $650 price tag though - maybe not.

We held a live stream the day this review launched at http://pcper.com/live.  You can see the replay that goes over our benchmark results and thoughts on the GTX 780 below.

 

The GeForce GTX 780 - A Cut Down GK110

As I mentioned above, the GTX 780 is a pared-down GK110 GPU and for more information on that particular architecture change, you should really take a look at my original GTX Titan launch article from February.  There is a lot more that is different on this part compared to GK104 than simple shader counts, but for gamers most of the focus will rest there. 

The chip itself is a 7.1 billion mega-ton beast though a card with the GTX 780 label is actually utilizing much fewer than that.  Below you will find a couple of block diagrams that represent the reduced functionality of the GTX 780 versus the GTX Titan:

NVIDIA's i500 SDR LTE Modem Achieves 150Mbps Throughput During CITA 2013 Demo

Subject: Mobile | May 22, 2013 - 04:46 PM |
Tagged: Tegra 4i, software defined radio, SoC, nvidia, i500, 4g lte

NVIDIA's Tegra 4i System on a Chip includes a software defined radio that works as a LTE modem. This i500 LTE modem uses general purpose deep execution processors (DXP) and is as much as 40% smaller than a hardware LTE modem according to the company.

At Mobile World Congress earlier this year, the modem was able to reach 100Mbps throughput. After a recent software update, the Tegra 4i SoC in NVIDIA's Pheonix reference platform achieved 150Mbps throughput in a demo at CITA 2013 in Los Angeles this week.

The reference phone was connected to a test network during the demo rather than a live cellular network. The cellular network test equiptment showed the Pheonix platform was connected at the full 150Mbps link speed. In addition to this, NVIDIA showed the Tegra 4i-powered Pheonix phone connected to a live AT&T LTE network streaming video and making voice calls.

The interesting bit about the i500 modem in the Tegra 4i is its software defined nature. NVIDIA was able to upgrade the modem's capabilites through software rather than needing to redesign the hardware. This would be a big plus to consumers as they would be able to take advantage of the faster network speeds as they become available without needing to replace their phones. NVIDIA did note that in addition to the LTE Cat 4 support, the i500 is also backwards compatible with LTE Cat 3, 3G, and 2G networks. I'm interested to see what the power consumption of thei500 is like compared to LTE modems implemented in specialized hardware. The i500 is smaller and more flexible, but SDR can use more power due to its general purpose hardware units.

Introduction and Design

P4212143.jpg

While Lenovo hasn’t historically been known for its gaming PCs, it’s poised to make quite a splash with the latest entry in its IdeaPad line. Owing little to the company’s business-oriented roots, the Y500 aims to be all power—moreso than any other laptop from the manufacturer to date—tactfully squeezed into a price tag that would normally be unattainable given the promised performance. But can it succeed?

Our Y500 review unit can be had for $1,249 at Newegg and other retailers, or for as low as $1,180 at Best Buy. Lenovo also sells customizable models, though the price is generally higher. Here’s the full list of specifications:

specs.png

The configurations offered by Lenovo range in price fairly widely, from as low as $849 for a model sporting 8 GB of RAM with a single GT 650M with 2 GB GDDR5. The best value is certainly this configuration that we received, however.

What’s so special about it? Well, apart from the obvious (powerful quad-core CPU and 16 GB RAM), this laptop actually includes two NVIDIA GeForce GT 650M GPUs (both with 2 GB GDDR5) configured in SLI. Seeing as it’s just a 15.6-inch model, how does it manage to do that? By way of a clever compromise: the exchange of the usual optical drive for an Ultrabay, something normally only seen in Lenovo’s ThinkPad line of laptops. So I guess the Y500 does owe a little bit of its success to its business-grade brethren after all.

P4212175.jpg

In our review unit (and in the particular configuration noted above), this Ultrabay comes prepopulated with the second GT 650M, equipped with its own heatsink/fan and all. The addition of this GPU effectively launches the Y500 into high-end gaming laptop territory—at least on the spec sheet. Other options for the Ultrabay also exist (sold separately), including a DVD burner and a second hard drive. The bay is easily removable via a switch on the back of the PC (see below).

JPR Releases Q1 2013 GPU Market Share Numbers, Good News for NVIDIA

Subject: Graphics Cards | May 20, 2013 - 09:54 AM |
Tagged: VIA, Q1 2013, nvidia, jpr, Intel, gpu market share, amd

Market analytics firm Jon Peddie Research recently released estimated market share and GPU shipment numbers from Q1 2013. The report includes information on AMD, NVIDIA, Intel, and Via and covered IGPs, processor graphics, and discrete GPUs included in desktop and mobile systems powered by X86 hardware. The report includes x86 tablets but otherwise does not factor in GPUs used in ARM devices like NVIDIA's Tegra chips. Year over Year, the PC market is down 12.6% and the GPU market declined by 12.9%. It is not all bad news for the PC market and discrete GPU makers, however. GPUs through 2016 are expected to exhibit a compound annual growth rate (CAGR) of 2.6% with as many as 394 million discrete GPUs shipped in 2016 alone.

In Q1 2013, the PC market is down 13.7% versus last quarter (Q4 2012) but the GPU market only declined 3.2%. This discrepency is explained as the result of people adding multiple GPUs to a single PC system, including adding a single discrete card to a system that already has processor graphics or an APU. By the end of Q1 2013, Intel holds 61.8% market share followed by AMD in second place with 20.2% and NVIDIA with 18%. Notably VIA is out of the game with 0.0% market share.

Q12013 Market Share.jpg

In terms of GPU shipments, NVIDIA had a relatively good first quarter of this year with an increase of 7.6% for notebook GPUs and desktop GPU shipments that remained flat. Overall, NVIDIA saw an increase in PC graphics shipments of 3.6%. On the other hand, x86 CPU giant Intel saw desktop and notebook GPUs slip by 3% and 6.3% respectively. Overall, that amounts to PC graphics shipments that fell by 5.3%. In between NVIDIA and Intel, AMD moved 30% more desktop chips (including APUs) versus Q4 2012. Meanwhile, Notebook chips (including APUs) fell by 7.3%. AMD's overall PC graphics shipments fell by 0.3%.

In all, this is decent news for the PC market as it shows that there is still interest in desktop GPUs. The PC market itself is declining and taking the GPU market with it, but it is far from the death of the desktop PC. It is interesting that NVIDIA (which announced Q1'13 revenue of $954.7 million) managed to push more chips while AMD and Intel were on the decline since NVIDIA doesn't have a x86 CPU with integrated graphics. I'm looking forward to seeing where NVIDIA stands as far as the mobile GPU market which does include ARM-powered products.

NVIDIA Announces Shield Pricing, Taking Pre-orders

Subject: General Tech, Mobile | May 14, 2013 - 06:06 AM |
Tagged: tegra 4, tegra, shield, project shield, nvidia

Solid information about the NVIDIA Shield (no longer called Project Shield) is finally becoming available with a blog post written up today on NVIDIA's website.  The company will begin accepting pre-orders from users that have previously signed up for the Shield mailing list while the rest of you will have to wait until May 20th to plop down your money. 

The cost?  $349.  Newegg, Gamestop, Micro Center and Canada Computer will carry it.

NV_Shield_Angled_Left_RealBoxing_LR.JPG

If you want to sign up for official June release schedule of the Tegra 4 powered mobile Android gaming device, you'll have to head over to shield.nvidia.com

NVIDIA does point out in the blog that the PC game streaming feature that I truly believe is the one thing that makes Shield a compelling gaming device, will be launching as BETA feature.

And GeForce game streaming, launching as a beta feature, will give SHIELD the power to access your NVIDIA GeForce GTX GPU-powered computer from the comfort of your couch. We’re working on streaming your favorite PC games to SHIELD, including great titles from Steam.

High level features of the device, for those of you that are unaware, include:

  • Tegra 4 – The world’s fastest mobile processor delivers rich graphics and unbeatable performance thanks to 72 GPU cores, four CPU cores and 2GB of RAM
  • Console-grade controller – Precise control thanks to dual analog joysticks, a full-sized D-Pad, left and right analog triggers, full-sized bumpers and A/B/X/Y buttons
  • Multi-touch display – 5-inch, 720p retinal multi-touch display for high-fidelity visuals
  • Integrated speakers – Custom, bass reflex, tuned port audio system – we think this is SHIELD’s sleeper feature
  • Wi-Fi – 802.11n 2X2 MIMO game-speed Wi-Fi for seamless game streaming
  • Pure Android – Latest Android Jelly Bean operating system from Google, for access to Android games and apps
  • There’s more – We put into SHIELD everything we would want in a premium mobile gaming device: 16 GB memory, GPS, Bluetooth 3.0, a mini-HDMI output, micro-USB 2.0, a microSD storage slot, a 3.5-mm stereo headphone jack. See the full spec sheet, here.

We took a look at the NVIDIA Shield device at CES this year and posted a video of our experiences, so check it out below. 

NVIDIA has also posted a separate blog that talks about some of the upcoming Android games that will highlight the power of the Tegra 4 mobile processor including Broken Age and Costume Quest from Double Fine, Chuck's Challenge from Niffler and more. 

Broken_Age_001_Wtrmrkd_2013.jpg

I think many people at NVIDIA as well as in the media are very curious to see what the reaction of Shield will actully be upon its release.  I am very excited to test it out in real-world, long term usage models but I definitely have doubts about the market's desire for another mobile gaming platform.

Pushing $1000 cards to 5760x1200

Subject: Graphics Cards | May 10, 2013 - 04:25 PM |
Tagged: titan, radeon hd 7990, nvidia, amd

If you have been wondering how the two flagship GPUs fare in a battle royal of pure frame rate you can satisfy your curiousity at [H]ard|OCP.  They have tested both NVIDIA's TITAN and the finally released HD7990 in one of their latest reviews.  Both cards were force to push out pixels at 5760x1200 and for the most part tied, which makes sense as they both cost $1000.  The real winner was Crossfired HD 7970's which kept up with the big guns but cost $200 less to purcahse.

If that isn't extreme enough for you, they also overclocked the TITAN in a seperate review.

"We follow-up with a look at how the $999 GeForce GTX TITAN compares to the new $999 AMD Radeon HD 7990 video card. What makes this is unique is that the GeForce GTX TITAN is a single-GPU running three displays in NV Surround compared to the same priced dual-GPU CrossFire on a card Radeon HD 7990 in Eyefinity."
