NVIDIA recently unveiled its GTX 770 GPU. Sitting between the GTX 680 and GTX 780, the Geforce GTX 770 is a refined GK104 with higher clockspeeds and improved GPU boost. It features 1536 CUDA cores and a 256-bit memory bus.
While the stock GTX 770 comes clocked at 1046 MHz base and 1085 MHz boost, ASUS is factory overclocking its DirectCU II OC card with a maximum boost GPU clockspeed of 1110 MHz. The 2GB of GDDR5 memory on the card will come clocked at 7010 MHz.
The differentiating factor here (aside from the overclock) is the custom DirectCU II cooler. ASUS has fitted the overclocked GTX 770 with a DirectCU cooler that uses copper heatpipes that directly contact the GPU and attach to an aluminum fin stack. The heatsink is, in turn, cooled by two 80mm fans. ASUS claims that the GTX 770 DirectCU II OC is up to 20% cooler and three-times quieter than the referrence NVIDIA cooler. Other features include a 10-phase DIGI+ VRM, and “Super Alloy Power” capacitors, chokes, and MOSFETs. The dual slot card is 10.7” long and includes two DL-DVI, one HDMI, and one DisplayPort video ouptut. ASUS' GPU Tweak software will allow users to adjust core and memory clockspeeds, voltage, fan speeds, and the power control target.
The ASUS GTX 770 DirectCU II OC is shipping now and will be available at retailers soon. In fact, the card is avaiable at Newegg right now for just under $410.

Earlier this year (beginning of April), NVIDIA introduced the first set of mobile graphics cards in its 700M series. These were relatively low-end cards that features at most 384 CUDA cores and were based on NVIDIA's 600-series Kepler architecture.
NVIDIA is now adding higher-end mobile GPUs to the 700M family with the GTX 760M, GTX 765M, GTX 770M, and GTX 780M. These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds. The GTX 780M is not quite the mobile equivalent to the desktop GTX 680, but NVIDIA is matching it up against AMD's 8970M GPU and claims that it can run games like Sleeping Dogs, Assassins Creed 3, and Borderlands 2 at Ultra settings (1080p). The GTX 770M is also capable of running modern games, though some detail setitng may need to be turned down.
The chart below details the various specifications and compares the new GTX 700M cards to the existing GT 700M GPUs. At the high end, NVIDIA has the GTX 780M with 1,536 CUDA cores, a base clock of 823 MHz, and 4GB of GDDR5 memory (1250 MHz) on a 256-bit bus. The GTX 770M occupies the mid-range mobile gaming slot with 960 CUDA cores, a base clock of 811 MHz, and a memory clock of 1GHz. The GTX 760M and GTX 765M have similar hardware specifications, but the GTX 765M has a higher GPU base clock of 850 MHz versus the GTX 760M's 657 MHz base clock. The low end GTX 700M GPUs (760M and 765M) feature 768 CUDA cores, a 128-bit memory bus, and memory clockspeeds of 1GHz.
|GTX 720M||GTX 735M||GT 740M||GT 750M||GTX 760M||GTX 765M||GTX 770M||GTX 780M|
|GPU Base Clock||938 MHz||889 MHz||980 MHz||967 MHz||657 MHz||850 MHz||811 MHz||823Mhz|
|Memory Clock||1000 MHz||1000 MHz||2500 MHz||2500 MHz||1000 MHz||1000 MHz||1000 MHz||1250 MHz|
Further, GPU Boost 2.0, Geforce Experience software, and NVIDIA Optimus support are features of the new GTX 700M graphics cards. You can read more about these NVIDIA technologies in this article by motherboard reviewer Morry Teitelman.
These cards are based on NVIDIA's 600-series despite the 700M moniker. They should provide OEMs with some good gaming options on the NVIDIA side of things and allow for some more competition in the gaming notebook hardware space against the existing AMD cards.

EVGA GTX 780 Hydro Copper GPUs
While NVIDIA restricted partners from going with aftermarket coolers on the company's GTX TITAN graphics card, the recently released NVIDIA GTX 780 does not appear to have the same limits placed upon it. As such, many manufacturers will be releasing GTX 780 graphics cards with custom coolers. One such design that caught my attention was the Hydro Copper full cover waterblock from EVGA.
This new cooler will be used on at least two upcoming EVGA graphics cards, the GTX 780 and GTX 780 Classified. EVGA has not yet announced clockspeeds or pricing for the Classified edition, but the GTX 780 Hydro Copper will be a GTX 780 GPU clocked at 980 MHz base and 1033 MHz boost. The 3GB of GDDR5 memory is stock clocked at 6008 MHz, however. It uses a single 8-pin and a single 6-pin PCI-E power connector. This card is selling for around $799 at retailers such as Newegg.
The GTX 780 Classified Hydro Copper will have a factory overclocked GTX 780 GPU and 3GB of GDDR5 memory at 6008 MHz, but beyond that details are scarce. The 8+8-pin PCI-E power connectors do suggest a healthy overclock (or at least that users will be able to push the cards after they get them).
Both the GTX 780 and GTX 780 Classified Hydro Copper graphics cards feature two DL-DVI, one HDMI, and one DisplayPort video outputs.
The Hydro Copper cooler itself is the really interesting bit about these cards though. It is a single slot, full cover waterblock that will cool the entire graphics card (GPU, VRM, Memory, ect). It has two inlet/outlet ports that can be swapped around to accommodate SLI setups or other custom water tube routing. A configurable LED-backlit EVGA logo adorns the side of the card and can be controlled in software. A 0.25 x 0.35 pin matrix is used in the portion of the block above the GPU to increase the surface area and aid in cooling. Unfortunately, while the card and cooler are single slot, you will actually need two case PCI expansion slots due to the two DL-DVI connectors.
It looks like a neat card, and it should perform well. I'm looking forward to seeing reviews of the card and how the cooler holds up to overclocking. Buying an overclocked card with a pre-installed waterblock is not for everyone but having a water cooled GPU with a warranty will be worth it more than pairing a stock card with a custom block.

$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.
"NVIDIA debuts the "new" GeForce GTX 770 today. The GeForce GTX 770 is poised to provide refreshed performance, for a surprising price. We evaluate a retail MSI GeForce GTX 770 Lightning flagship video card from MSI with specifications that will make any enthusiast smile. The $399 price point just got a kick in the pants."

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.
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.

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.
"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.
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:

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
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:
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.
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).

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.
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.
