Origin PC has announced that it will be integrating Haswell CPUs and GTX700M GPUs into its line of gaming notebooks and desktops. Specifically, Origin PC will add Haswell CPUs to its Genesis, Millennium, and Chronos desktop PCs. Origin PC is also outfitting its EON gaming laptops with both Haswell CPU and GTX700M GPU upgrades. And to sweeten the pot (if only slightly), Origin is bundling a voucher for Grid 2 with each Haswell-equipped Origin PC order.
Both the EON15-S and EON17-S gaming laptops feature Intel Haswell processors, NVIDIA GTX700M or Quadro K1000M mobile graphics cards, and up to five storage drives when the optical drive is removed. The laptops are even able to have an independent RAID of two mSATA SSDs and two hard drives or SSDs along with a non-RAID storage drive in the optical bay—that's a lot of storage for a laptop!
The laptops come with customizable display lids available in red, black, silver, or a custom air brush as well as back-lit keyboards and touchpads. As the SKU names suggest, the EON15-S has a 15.6” display while the EON17-S has a 13.3” display. Origin PC is further offering factory overclocking for the Haswell processors and GTX700M graphics cards. The company claims up to a 20-times power reduction during idle thanks to the more power-efficient hardware.
Unfortunately, all this new tech comes at a premium, and the EON15-S and EON17-S gaming notebooks start at $1,722 and $1,784 respectively. As far as the desktops go, there is also a slight bump in price depending on the Haswell chip you select during the customization process. Upgrading to an Intel Core i7-4770K on the GENESIS desktop costs an extra $193, for example.
You can find more information on the Origin PC website.

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.

$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.
Our 4K Testing Methods
You may have recently seen a story and video on PC Perspective about a new TV that made its way into the office. Of particular interest is the fact that the SEIKI SE50UY04 50-in TV is a 4K television; it has a native resolution of 3840x2160. For those that are unfamiliar with the new upcoming TV and display standards, 3840x2160 is exactly four times the resolution of current 1080p TVs and displays. Oh, and this TV only cost us $1300.
In that short preview we validated that both NVIDIA and AMD current generation graphics cards support output to this TV at 3840x2160 using an HDMI cable. You might be surprised to find that HDMI 1.4 can support 4K resolutions, but it can do so only at 30 Hz (60 Hz 4K TVs won't be available until 2014 most likely), half the refresh rate of most TVs and monitors at 60 Hz. That doesn't mean we are limited to 30 FPS of performance though, far from it. As you'll see in our testing on the coming pages we were able to push out much higher frame rates using some very high end graphics solutions.
I should point out that I am not a TV reviewer and I don't claim to be one, so I'll leave the technical merits of the monitor itself to others. Instead I will only report on my experiences with it while using Windows and playing games - it's pretty freaking awesome. The only downside I have found in my time with the TV as a gaming monitor thus far is with the 30 Hz refresh rate and Vsync disabled situations. Because you are seeing fewer screen refreshes over the same amount of time than you would with a 60 Hz panel, all else being equal, you are getting twice as many "frames" of the game being pushed to the monitor each refresh cycle. This means that the horizontal tearing associated with Vsync will likely be more apparent than it would otherwise.
I would likely recommend enabling Vsync for a tear-free experience on this TV once you are happy with performance levels, but obviously for our testing we wanted to keep it off to gauge performance of these graphics cards.

Tagged: rumor, nvidia, kepler, gtx 700, geforce 700, computex
Recent rumors seem to suggest that NVIDIA will release its desktop-class GeForce 700 series of graphics cards later this year. The new card will reportedly be faster than the currently-available GTX 600 series, but will likely remain based on the company's Kepler architecture.
According to the information presented during NVIDIA's GTC keynote, its Kepler architecture will dominate 2012 and 2013. It will then follow up with Maxwell-based cards in 2014. Notably absent from the slides are product names, meaning the publicly-available information at least leaves the possibility of a refreshed Kepler GTX 700 lineup in 2013 open.
Fudzilla further reports that NVIDIA will release the cards as soon as May 2013, with an official launch as soon as Computex. Having actual cards available for sale by Computex is a bit unlikely, but a summer launch could be possible if the new 700 series is merely a tweaked Kepler-based design with higher clocks and/or lower power usage. The company is rumored to be accelerating the launch of the GTX 700 series in the desktop space in response to AMD's heavy game-bundle marketing, which seems to be working well at persuading gamers to choose the red team.
What do you make of this rumor? Do you think a refreshed Kepler is coming this year?

Last month, NVIDIA revealed its Kayla development platform that combines a quad core Tegra System on a Chip (SoC) with a NVIDIA Kepler GPU. Kayla will out later this year, but that has not stopped other board makers from putting together their own solutions. One such solution that began shipping earlier this week is the mITX GPU Devkit from SECO.
The new mITX GPU Devkit is a hardware platform for developers to program CUDA applications for mobile devices, desktops, workstations, and HPC servers. It combines a NVIDIA Tegra 3 processor, 2GB of RAM, and 4GB of internal storage (eMMC) on a Qseven module with a Mini-ITX form factor motherboard. Developers can then plug their own CUDA-capable graphics card into the single PCI-E 2.0 x16 slot (which actually runs at x4 speeds). Additional storage can be added via an internal SATA connection, and cameras can be hooked up using the CIC headers.
Rear IO on the mITX GPU Devkit includes:
- 1 x Gigabit Ethernet
- 3 x USB
- 1 x OTG port
- 1 x HDMI
- 1 x Display Port
- 3 x Analog audio
- 2 x Serial
- 1 x SD card slot
The SECO platform is a proving to be popular for GPGPU in the server space, especially with systems like Pedraforca. The intention of using these types of platforms in servers is to save power by using a low power ARM chip for inter-node communication and basic tasks while the real computing is done solely on the graphics cards. With Intel’s upcoming Haswell-based Xeon chips getting down to 13W TPDs though, systems like this are going to be more difficult to justify. SECO is mostly positioning this platform as a development board, however. One use in that respect is to begin optimizing GPU-accelerated code for mobile devices. With future Tegra chips to get CUDA-compatible graphics cards, new software development and optimization of existing GPGPU code for smartphones and tablet will be increasingly important.
Either way, the SECO mITX GPU Devkit is available now for 349 EUR or approximately $360 (in both cases, before any taxes).

Two new photos recently popped up on Cowcotland, showing off an unreleased "Dragon Edition" GTX 660 Ti graphics card from ASUS. The new card boasts some impressive factory overclocks on both the GPU and memory as well as a beefy heatsink and a new blue and black color scheme.
The ASUS GTX 660 Ti Dragon will feature a custom cooler with two fans and an aluminum heastink. The back of the card includes a metal backplate to secure the cooler and help dissipate a bit of heat itself. However, there is also a cutout in the backplate to allow for (likely) additional power management circuitry. The card also features the company's power phase technology, NVIDIA's 660 Ti GK-104 GPU, and 2GB of GDDR5 memory. The graphics core is reportedly clocked at 1150MHz (no word on whether that is the base or boost figure) while the memory is overclocked to 6100MHz. For comparison, the reference GTX 660 Ti clocks are 915MHz base, 980MHz boost, and 6,000MHz memory. The new card will support DVI, DisplayPort, and HDMI video outputs.
There is no word on pricing or availability, but the Dragon looks like it will be one of the fastest GTX 660 Ti cards available when (if?) it publicly released!
NVIDIA releases the GeForce GT 700M family
NVIDIA revolutionized gaming on the desktop with the release of its 600-series Kepler-based graphics cards in March 2012. With the release of the GeForce GT 700M series, Kepler enters the mobile arena to power laptops, ultrabooks, and all-in-one systems.
Today, NVIDIA introduces four new members to its mobile line: the GeForce GT 750M, the GeForce GT 740M, the GeForce GT 735M, and the GeForce GT 720M. These four new mobile graphics processors join the previously-released members of the GeForce GT 700m series: the GeForce GT 730M and the GeForce GT 710M. With the exception of the Fermi-based GeForce GT 720M, all of the newly-released mobile cores are based on NVIDIA's 28nm Kepler architecture.
Notebooks based on the GeForce GT 700M series will offer in-built support for the following new technologies:
Automatic Battery Savings through NVIDIA Optimus Technology
Automatic Game Configuration through the GeForce Experience
Automatic Performance Optimization through NVIDIA GPU Boost 2.0
