To start off with the good news, the GTX 760 is now available between $250 to $260 for the MSI model that [H]ard|OCP reviewed. No paper launch this, nor another $400+ card for you to dream about but instead a solid performing card at a decent price. Power is provide by an 8-pin and a 6-pin PCIe power connector, perhaps a little more than the card needs but perfect for overclockers who need the extra juice. Performance wise the card trumps the GTX 660Ti and matches the GTX 670 and HD7950 boost in almost every test, for a good $50-75 less to pick up. Even better news is that some certain sites testing Frame Rating and SLI performance saw great scaling in real performance.
"Today NVIDIA is launching the GeForce GTX 760. The GeForce GTX 760 will be replacing a video card and offering what use to be high-end memory performance, at a mainstream price. We will evaluate a retail MSI N760 TF 2GD5/OC video card with comparisons to find out whether or not this is a true value."

Getting even more life from GK104
Have you guys heard about this new GPU from NVIDIA? It’s called GK104 and it turns out that the damn thing is found yet another graphics card this year – the new GeForce GTX 760. Yup, you read that right, what NVIDIA is saying is the last update to the GeForce lineup through Fall 2013 is going to be based on the same GK104 design that we have previously discussed in reviews of the GTX 680, GTX 670, GTX 660 Ti, GTX 690 and more recently, the GTX 770. This isn’t a bad thing though! GK104 has done a fantastic job in every field and market segment that NVIDIA has tossed it into with solid performance and even better performance per watt than the competition. It does mean however that talking up the architecture is kind of mind numbing at this point…
If you are curious about the Kepler graphics architecture and the GK104 in particular, I’m not going to stop you from going back and reading over my initial review of the GTX 680 from January of 2012. The new GTX 760 takes the same GPU, adds a new and improved version of GPU Boost (the same we saw in the GTX 770) and lowers down the specifications a bit to enable NVIDIA to hit a new price point. The GTX 760 will be replacing the GTX 660 Ti – that card will be falling into the ether but the GTX 660 will remain, as will everything below it including the GTX 650 Ti Boost, 650 Ti and plain old 650. The GTX 670 went the way of the dodo with the release of the GTX 770.
Even though the GTX 690 isn't on this list, NVIDIA says it isn't EOL
As for the GeForce GTX 760 it will ship with 1152 CUDA cores running at a base clock of 980 MHz and a typical boost clock of 1033 MHz. The memory speed remains at 6.0 GHz on a 256-bit memory bus and you can expect to find both 2GB and 4GB frame buffer options from retail partners upon launch. The 1152 CUDA cores are broken up over 6 SMX units and that means you’ll see some parts with 3 GPCs and others with 4 – NVIDIA claims any performance delta between them will be negligible.

Well, the date has been set. AMD publicly stated on its @AMDRadeon Twitter account that a new version the prototype driver we originally previewed with the release of the Radeon HD 7990 in April will be released to the public on July 31st. For a problem that many in the industry didn't think existed.
Big news for CrossFire! We plan to release our driver that delivers improved multi-GPU frame pacing on July 31. More info soon.
— AMD Radeon Graphics (@AMDRadeon) June 20, 2013
Since that April release AMD has been very quiet about its driver changes and actually has refused to send me updated prototypes over the spring. Either they have it figured out or they are worried they haven't - but it looks like we'll find out at the end of next month and I feel pretty confident that the team will be able to address the issues we brought to light.
For those of you that might have missed the discussion, our series of Frame Rating stories will tell you all about the issues with frame pacing and stutter in regards to AMD's CrossFire multi-GPU technology.
- Frame Rating Dissected: Full Details on Capture-based Graphics Performance Testing
- Frame Rating: Visual Effects of Vsync on Gaming Animation
- Frame Rating: AMD Improves CrossFire with Prototype Driver
AMD gave the media a prototype driver in April to test with the Radeon HD 7990, a card that depends on CrossFire to work correctly, and the improvements were pretty drastic.
So what can we expect on July 31st? A driver that will give users the option to disable or enable the frame pacing technology they are developing - though I am still of the mindset that disabling is never advantageous. More to come in the next 30 days!

There have been rumors of a new mid-range Kepler-based graphics card coming that will be next entry in the GTX 700-series. This new GPU is rumored to be called the GeForce GTX 760. If the specifications are true, the card will fit between the existing GTX 660 and GTX 660 Ti graphics cards as far as hardware specifications and pricing. While it will be under the GTX 700-series, it will not have the faster 7Gbps memory clockspeed of the other 700-series cards.
As far as specifications, Videocardz claims to have the final specifications list in a recent news post. The GTX 760 is rumored to be the latest graphics card to use NVIDIA's GK-104 "Kepler" GPU. The GTX 760 will have some units disabled for a GPU with 1,152 CUDA cores, 96 Texture Manipulation Units (TMUs), and 32 Raster Operations Processors (ROPs). The GPU supports NVIDIA's latest GPU Boost 2.0 technology which will automatically ratchet up the Boost clockspeed so long as temperature allows. It has a base clockspeed of 980 MHz and a boost clockspeed of 1,033 Mhz.
GTX 760 graphics cards will allegedly come in both 2GB and 4GB GDDR5 memory flavors. NVIDIA is clocking the memory at 6 Gbps (1502 MHz), which makes it the fist 700-series part to not take advantage of faster memory chips. However, there is a bit of saving grace as NVIDIA has moved to a 256-bit memory bus. This allows the card to still see a respectable bump in memory bandwidth of 192 GB/s on the GTX 760 versus the GTX 660/GTX 660 Ti's 144.2 GB/s bandwidth.
Compared to the existing mid-range 600-series cards, the GTX 760 has base and boost GPU clockspeeds equal to the GTX 660 (and faster than the GTX 660 TI). Memory clockspeed is also unchanged on the new card, though it has a wider memory bus. The GTX 760 has 192 more CUDA cores than the GTX 660, but 192 fewer CUDA cores versus the GTX 660 Ti. TMUs are also sit evenly between the two 600-series cards, but the GTX 760 does have 8 more ROPs enabled than both the 660 and 660 Ti.
Graphics cards with the upcoming GTX 760 GPU will be powered by two 6-pin PCI-E power connectors, and it has a 170W TDP. That power consumption puts the card between the 150W GTX 660 Ti and the higher-end 230W GTX 770. It appears that the card will not come with the high-end stock metallic cooler used in the other 700-series cards, though the various AIBs are likely to fit the GPU with their own custom aftermarket coolers. Video outputs on the cards will incluce DVI-I, DVI-D, HDMI, and DisplayPort.
The chart below compares the specifications between the GTX 660, GTX 660 Ti, GTX 770, and the rumored GTX 760.
|GTX 760||GTX 660||GTX 660 Ti||GTX 770|
|GPU Base||980 MHz||980 Mhz||915 Mhz||1046 Mhz|
|GPU Boost||1033 MHz||1033 MHz||980 Mhz||1085 MHz|
|Memory Clock||1502 MHz||1502 MHx||1502 Mhz||1752 Mhz|
|Bandwidth||192 GB/s||144.2 GB/s||144.2 GB/s||224 GB/s|
|TDP||170 W||140 W||150 W||230 W|
The card is supposedly going to be released on June 25th for around $300. It will compete with AMD's 7950 with boost graphics card. Further, the card will be an alternative to NVIDIA's own GTX 660 Ti and an upgrade for gamers still running GTX 560 cards with the company's older Fermi-based GPU.

Yesterday we all saw the blog piece from NVIDIA that stated that they were going to start licensing their IP to interested third parties. Obviously, there was a lot of discussion about this particular move. Some were in favor, some were opposed, and others yet thought that NVIDIA is now simply roadkill. I believe that it is an interesting move, but we are not yet sure of the exact details or the repercussions of such a decision on NVIDIA’s part.
The biggest bombshell of the entire post was that NVIDIA would be licensing out their latest architecture to interested clients. The Kepler architecture powers the very latest GTX 700 series of cards and at the top end it is considered one of the fastest and most efficient architectures out there. Seemingly, there is a price for this though. Time to dig a little deeper.
Kepler will be the first technology licensed to third party manufacturers. We will not see full GPUs, these will only be integrated into mobile products.
The very latest Tegra parts from NVIDIA do not feature the Kepler architecture for the graphics portion. Instead, the units featured in Tegra can almost be described as GeForce 7000 series parts. The computational units are split between pixel shaders and vertex shaders. They support a maximum compatibility of D3D 9_3 and OpenGL ES 2.0. This is a far cry from a unified shader architecture and support for the latest D3D 11 and OpenGL ES 3.0 specifications. Other mobile units feature the latest Mali and Adreno series of graphics units which are unified and support DX11 and OpenGL ES 3.0.
So why exactly does the latest Tegras not share the Kepler architecture? Hard to say. It could be a variety of factors that include time to market, available engineering teams, and simulations which could dictate if power and performance can be better served by a less complex unit. Kepler is not simple. A Kepler unit that occupies the same die space could potentially consume more power with any given workload, or conversely it could perform poorly given the same power envelope.
We can look at the desktop side of this argument for some kind of proof. At the top end Kepler is a champ. The GTX 680/770 has outstanding performance and consumes far less power than the competition from AMD. When we move down a notch and see the GTX 660 Ti/HD 7800 series of cards, we see much greater parity in performance and power consumptions. Going to the HD 7790 as compared to the 650 Ti Boost, we see the Boost part have slightly better performance but consumes significantly more power. Then we move down to the 650 and 650 Ti and these parts do not consume any more power than the competing AMD parts, but they also perform much more poorly. I know these are some pretty hefty generalizations and the engineers at NVIDIA could very effectively port Kepler over to mobile applications without significant performance or power penalties. But so far, we have not seen this work.
Power, performance, and die area aside there is also another issue to factor in. NVIDIA just announced that they are doing this. We have no idea how long this effort has been going, but it is very likely that it has only been worked on for the past six months. In that time NVIDIA needs to hammer out how they are going to license the technology, how much manpower they must provide licensees to get those parts up and running, and what kind of fees they are going to charge. There is a lot of work going on there and this is not a simple undertaking.
So let us assume that some three months ago an interested partner such as Rockchip or Samsung comes knocking to NVIDIA’s door. They work out the licensing agreements and this takes several months. Then we start to see the transfer of technology between the companies. Obviously Samsung and Rockchip are not going to apply this graphics architecture to currently shipping products, but will instead bundle it in with a next generation ARM based design. These designs are not spun out overnight. For example, the 64 bit ARMv8 designs have been finalized for around a year, and we do not expect to see initial parts being shipped until late 1H 2014. So any partner that decides to utilize NVIDIA’s Kepler architecture for such an application will not see this part be released until 1H 2015 at the very earliest.
Sheild is still based on a GPU posessing separate pixel and vertex shaders. DX11 and OpenGL ES 3.0? Nope!
If someone decides to license this technology from NVIDIA, it will not be of great concern. The next generation of NVIDIA graphics will already be out by that time, and we could very well be approaching the next iteration for the desktop side. NVIDIA plans on releasing a Kepler based mobile unit in 2014 (Logan), which would be a full year in advance of any competing product. In 2015 NVIDIA is planning on releasing an ARM product based on the Denver CPU and Maxwell GPU. So we can easily see that NVIDIA will only be licensing out an older generation product so it will not face direct competition when it comes to GPUs. NVIDIA obviously is hoping that their GPU tech will still be a step ahead of that of ARM (Mali), Qualcomm (Adreno), and Imagination Technologies (PowerVR).
This is an easy and relatively painfree way to test the waters that ARM, Imagination Technologies, and AMD are already treading. ARM only licenses IP and have shown the world that it can not only succeed at it, but thrive. Imagination Tech used to produce their own chips much like NVIDIA does, but they changed direction and continue to be profitable. AMD recently opened up about their semi-custom design group that will design specific products for customers and then license those designs out. I do not think this is a desperation move by NVIDIA, but it certainly is one that probably is a little late in coming. The mobile market is exploding, and we are approaching a time where nearly every electricity based item will have some kind of logic included in it, billions of chips a year will be sold. NVIDIA obviously wants a piece of that market. Even a small piece of “billions” is going to be significant to the bottom line.
OpenCL Support in a Meaningful Way
Adobe had OpenCL support since last year. You would never benefit from its inclusion unless you ran one of two AMD mobility chips under Mac OSX Lion, but it was there. Creative Cloud, predictably, furthers this trend with additional GPGPU support for applications like Photoshop and Premiere Pro.
This leads to some interesting points:
- How OpenCL is changing the landscape between Intel and AMD
- What GPU support is curiously absent from Adobe CC for one reason or another
- Which GPUs are supported despite not... existing, officially.
This should be very big news for our readers who do production work whether professional or for a hobby. If not, how about a little information about certain GPUs that are designed to compete with the GeForce 700-series?

Tagged: radeon, nvidia, geforce, frostbite 3, ea, dice, amd
The original source article at IGN.com has been updated with some new information. Now they are saying the agreement between AMD and EA is "non-exclusive and gamers using other components will be supported."
The quote from an EA rep says as follows:
DICE has a partnership with AMD specifically for Battlefield 4 on PC to showcase and optimize the game for AMD hardware," an EA spokesperson said. "This does not exclude DICE from working with other partners to ensure players have a great experience across a wide set of PCs for all their titles.
END UPDATE #3
This could be a huge deal for NVIDIA and AMD in the coming months - according to a story at IGN.com, AMD has entered into an agreement with EA that will allow them exclusive rights to optimization for all games based around the Frostbite 3 engine. That includes Battlefield 4, Mirror's Edge 2, Need for Speed Rivals and many more games due out this year and in 2014. Here is the quote that is getting my attention:
Starting with the release of Battlefield 4, all current and future titles using the Frostbite 3 engine — Need for Speed Rivals, Mirror's Edge 2, etc. — will ship optimized exclusively for AMD GPUs and CPUs. While Nvidia-based systems will be supported, the company won't be able to develop and distribute updated drivers until after each game is released.
Battlefield 4 will be exclusive optimized for AMD hardware.
This is huge news for AMD as the Frostbite 3 engine will be used for all EA published games going forward with the exception of sports titles. The three mentioned above are huge but this also includes Star Wars Battlefront, Dragon Age and even the next Mass Effect so I can't really emphasize enough how big of a win this could be for AMD's marketing and developer relations teams.
I am particularly interested in this line as well:
While Nvidia-based systems will be supported, the company won't be able to develop and distribute updated drivers until after each game is released.
The world of PC optimizations and partnerships has been around for a long time so this isn't a huge surprise for anyone that follows PC gaming. What is bothersome to me is that both EA and AMD
are saying are rumored to have agreed that NVIDIA won't get access to the game as it is being developed - something that is CRUCIAL for day-of driver releases and performance tweaks for GeForce card owners. In most cases, both AMD and NVIDIA developer relations teams get early access to game builds for PC titles in order to validate compatibility and to improve performance of these games for the public release. Without these builds, NVIDIA would be at a big disadvantage. This is exactly what happend with the recent Tomb Raider release.
AMD called me to reiterate their stance that competition does not automatically mean cutting out the other guy. In the Tomb Raider story linked above, Neil Robison, AMD's Senior Director of Consumer and Graphics Alliances, states quite plainly: "The thing that angers me the most is when I see a request to debilitate a game. I understand winning, I get that, and I understand aggressive companies, I get that. Why would you ever want to introduce a feature on purpose that would make a game not good for half the gaming audience?"
So what do we take away from that statement, made in a story published in March, and today's rumor? We have to take AMD at its word until we see solid evidence otherwise, or enough cases of this occurring to feel like I am being duped but AMD wants us all to know that they are playing the game the "right way." That stance just happens to be counter to this rumor.
NVIDIA had performance and compatibility issues with Tomb Raider upon release.
The irony in all of this is that AMD has been accusing NVIDIA of doing this exact thing for years - though without any public statements from developers, publishers or NVIDIA. When Batman: Arkham Asylum was launched AMD basically said that NVIDIA had locked them out of supporting antialiasing. In 2008, Assassin's Creed dropped DX 10.1 support supposedly because NVIDIA asked them too, who didn't have support for it at the time in GeForce cards. Or even that NVIDIA was disabling cores for PhysX CPU support to help prop up GeForce sales. At the time, AMD PR spun this as the worst possible thing for a company to do in the name of gamers, that is was bad for the industry, etc. But times change as opportunity changes.
The cold truth is that this is why AMD decided to take the chance that NVIDIA was allegedly unwilling to and take the console design wins that are often noted as being "bad business." If settling for razor thin margins on the consoles is a risk, the reward that AMD is hoping to get is exactly this: benefits in other markets thanks to better relationships with game developers.
Will the advantage be with AMD thanks to PS4 and Xbox One hardware?
At E3 I spoke in-depth with both NVIDIA and AMD executives about this debate and as you might expect both have very different opinions about what is going to transpire in the next 12-24 months. AMD views this advantage (being in the consoles) as the big bet that is going to pay off for the more profitable PC space. NVIDIA thinks that AMD still doesn't have what it takes to truly support developers in the long run and they don't have the engineers to innovate on the technology side. In my view, having Radeon-based processors in the Xbox One and Playstation 4 (as well as the Wii U I guess) gives AMD a head start but won't win them the race for the hearts and minds of PC gamers. There is still a lot of work to be done for that.
Before this story broke I was planning on outlining another editorial on this subject and it looks like it just got promoted to a top priority. There appear to be a lot of proverbial shoes left to drop in this battle, but it definitely needs more research and discussion.
Remember the issues with Batman: Arkham Asylum? I do.
I asked both NVIDIA and AMD for feedback on this story but only AMD has replied thus far. Robert Hallock, PR manager for gaming and graphics, Graphics Business Unit at AMD sent me this:
It makes sense that game developers would focus on AMD hardware with AMD hardware being the backbone of the next console generation. At this time, though, our relationship with EA is exclusively focused on Battlefield 4 and its hardware optimizations for AMD CPUs, GPUs and APUs.
Not much there, but he is also not denying of the original report coming from IGN. It might just be too early for a more official statement. I will update this story with information from NVIDIA if I hear anything else.
What do YOU think about this announcement though? Is this good news for AMD and bad news for NVIDIA? Is it good or bad for the gamer and in particular, the PC gamer? Your input will help guide or upcoming continued talks with NVIDIA and AMD on the subject.
Just so we all have some clarification on this and on the potential for validity of the rumor, this is where I sourced the story from this afternoon:
END UPDATE #2
Kepler-based Mobile GPUs
Late last month, just before the tech world blew up from the mess that is Computex, NVIDIA announced a new line of mobility discrete graphics parts under the GTX 700M series label. At the time we simply posted some news and specifications about the new products but left performance evaluation for a later time. Today we have that for the highest end offering, the GeForce GTX 780M.
As with most mobility GPU releases it seems, the GTX 700M series is not really a new GPU and only offers cursory feature improvements. Based completely on the Kepler line of parts, the GTX 700M will range from 1536 CUDA cores on the GTX 780M to 768 cores on the GTX 760M.
The flagship GTX 780M is essentially a desktop GTX 680 card in a mobile form factor with lower clock speeds. With 1536 CUDA cores running at 823 MHz and boosting to higher speeds depending on the notebook configuration, a 256-bit memory controller running at 5 GHz, the GTX 780M will likely be the fastest mobile GPU you can buy. (And we’ll be testing that in the coming pages.)
The GTX 760M, 765M and 770M offering ranges of performance that scale down to 768 cores at 657 MHz. NVIDIA claims we’ll see the GTX 760M in systems as small as 14-in and below with weights at 2kg or so from vendors like MSI and Acer. For Ultrabooks and thinner machines you’ll have to step down to smaller, less power hungry GPUs like the GT 750 and 740 but even then we expect NVIDIA to have much faster gaming performance than the Haswell-based processor graphics.
