The participants in this System on a Chip showdown both bear long names, on one side is NVIDIA's Tegra 3 ARM SoC and on the other the ODROID-X Samsung Exynos 4412 quad-core ARM Cortex-A9.  NVIDIA's offering is well known by now but the ODROID-X is a relative newcomer to the market, offering their product for about $130.  After setting up Linux on these systems Phoronix got to benchmarking and the results will surprise NVIDIA fans as the ARM based system actually came out on top on quite a few of the tests.

"While not as popular as NVIDIA's Tegra 3 ARM SoC, the Samsung Exynos 4412 quad-core ARM Cortex-A9 found on cheaply priced ODROID-X can actually outperform the quad-core NVIDIA ARM processor. Here are benchmarks of the $129 USD ODROID-X benchmarked against the NVIDIA Tegra 3 reference tablet and a PandaBoard ES running the Texas Instruments OMAP4460."

Meet the many varieties of GTX 660 Ti

Launch day for the GTX 660 Ti is here and there are a long list of reviews to go through.  Not only have all of the major vendors released a card, they've also released overclocked and custom cooled cards which could make choosing the model you want difficult. [H]ard|OCP received a reference model from Galaxy, which is a perfect example of how the base 2GB version of the card will perform.  They also received an overclocked 3G model with custom cooling and a 10" board which is bigger than some other models.  Performance wise, the 2GB model is a perfect choice for anyone using a GTX 460 or equivalent and is looking for an upgrade.  The 3GB model is more interesting, often out performing an HD 7950 and doing so at a similar, if not lower, price. 

You can also read Ryan's take on the MSI version of the 660 Ti, with a round up scheduled to appear later this week.

"NVIDIA is launching its third Kepler GPU for 2012, the GeForce GTX 660 Ti. We have a retail GTX 660 Ti video card on tap from GALAXY to evaluate along with reference clocked GTX 660 Ti. We've got a lot of comparisons that show how the GTX 660 Ti will upgrade you from not just one, but two GPU generations past."

Another GK104 Option for $299

If you missed our live stream with PC Perspective's Ryan Shrout and NVIDIA's Tom Petersen discussing the new GeForce GTX 660 Ti you can find the replay at this link!!

While NVIDIA doesn't like us to use the codenames anymore, very few GPUs are as flexible and as stout as the GK104.  Originally released with the GTX 680 and then with the dual-GPU beast known as the GTX 690 and THEN with the more modestly priced GTX 670, this single chip has caused AMD quite a few headaches.  It appears things will only be worse with the release of the new GeForce GTX 660 Ti today, once again powered by GK104 and the Kepler architecture at the $299 price point.

01.jpg

While many PC gamers lament about the lack of games that really push hardware today, NVIDIA has been promoting the GTX 660 Ti as the upgrade option of choice for gamers on a 2 -4 year cycle.  Back in 2008 the GTX 260 was the mid-range enthusiast option while in 2010 it was the GTX 470 based on Fermi.  NVIDIA claims GTX 260 users will see more than 3x the performance increase with the 660 Ti all while generating those pixels more efficiently. 

blockdiagram.jpg

I mentioned that the GeForce GTX 660 Ti was based on GK104 and what you mind find interesting is that it is nearly identical to the specifications of the GTX 670.  Both utilize 7 SMXs for a total of 1344 stream processors or CUDA cores and both run at a reference clock speed of 915 MHz base and 980 MHz Boost.  Both include 112 texture units though the GeForce GTX 660 Ti does see a drop in ROP count from 32 to 24 and L2 cache drops from 512KB to 384KB.  Why?

Spicing up the GTX 670

The Power Edition graphics card series from MSI is a relatively new addition to its lineup. The Power Edition often mimics that of the higher-end Lightning series, but at a far lower price (and perhaps a smaller feature set). This allows MSI to split the difference between the reference class boards and the high end Lightning GPUs.

msi_gtx670_pe_01.jpg

Doing this allows users a greater variety of products to choose from, and to better tailor users' purchases by their needs and financial means. Not everyone wants to pay $600 for a GTX 680 Lightning, but what if someone was able to get similar cooling, quality, and overclocking potential for a much lower price?  This is what MSI has done with one of its latest Power Edition cards.

The GTX 670 Power Edition

The NVIDIA GTX 670 cards have received accolades throughout the review press. It is a great combination of performance, power consumption, heat production, and price. It certainly caused AMD a great amount of alarm, and it hurriedly cut prices on the HD 7900 series of cards in response. The GTX 670 is a slightly cut-down version of the full GTX 680, and it runs very close to the clock speed of its bigger brother. In fact, other than texture and stream unit count, the cards are nearly identical.

NVIDIA GTX 660 Ti Cards For Sale at CompUSA

Tagged: nvidia, kepler, gtx 660ti, gpu boost, gpu

Gamers have been eagerly awaiting the release of the midrange NVIDIA graphics card thanks to some rather enticing rumors and leaks. Due to launch sometime soon, the GTX 660 Ti is packing some quality hardware and may be the next 8800GT as far as popularity levels with gamers craving the best price/performance. However, that is dependent on pricing–which has been up in the air for a while. Rumored prices have included an MSRP of $349 and retail pre-orders for $299 and just under $400 (and guesses everywhere in between).

US-based computer retailer CompUSA has provided us with further information that suggests the price will, in fact, be the ever-desired $299 price point rather than previous rumors that suggested it would be priced closer to the GTX 670. Gamers rejoice!

Compusa_has_GTX 660Ti Cards.jpg

Specifically, a reference version of the PNY-manufactured NVIDIA GTX 660 Ti recently appears on CompUSA’s website where customers could purchase it. This card is listed as being model number “VCGGTX660TXPB-C Bundle.” While it is unclear what the “-C” designator means, it is more proof that it is the same (or a very similar) model as the card leaked by MacMall (when it showed up for pre-order ahead of the release date). Speaking of bundles, the CompUSA card gets even better as it is the PNY GTX 660 Ti and a game coupon for Borderlands 2 for the $299 price–not bad at all.

While I have not personally ordered one (so I can’t confirm if CompUSA will actually sell it to me ahead of the official release or if it was just a mistake on its part for making the store page live early), you can try to get your hands on the 660 Ti now for $299 USD.

I’m extremely happy to see the $299 price, and I look forward to see the cards from other manufacturers. Custom and factory overclocked cards should also be interesting as far as pricing and where they fit compared to saving up a bit more money and simply going with a GTX 670. What do you think, will you be picking one of these graphics cards up?

Overclocked and 4GB Strong

Even though the Kepler GK104 GPU is now matured in the market, there is still a ton of life left in this not-so-small chip and Galaxy sent us a new graphics card to demonstrate just that.  The Galaxy GeForce GTX 670 GC 4GB card that we are reviewing today takes the GTX 670 GPU (originally released and reviewed on May 10th) and juices it up on two different fronts: clock rates and memory capacity.

IMG_7221.JPG

The Galaxy GTX 670 GC 4GB graphics card is based on GK104 as mentioned below and meets most of the same specifications as the reference GTX 670.  That includes 1344 CUDA cores or stream processors, 112 texture units and 32 ROP units along with a 256-bit GDDR5 memory bus. 

The GC title indicates that the Galaxy GTX 670 GC 4GB is overclocked as well - this card runs at 1006 MHz base clock, 1085 MHz Boost clock and 1500 MHz memory clock.  Compared to the defaults of 915 MHz, 980 MHz and 1500 MHz (respectively) this Galaxy model gets a 10% increase in clock speed though we'll see how much that translates into gaming performance as we go through our review.

Of course, also in the title of the review, the Galaxy GTX 670 GC includes 4GB of frame buffer, twice as much as the reference cards.  The goal is obviously to attract gamers with high resolution screens (2560x1600 or 2560x1440) as well as users interested in triple panel NVIDIA Surround gaming.  We test both of those resolutions in our game collection on the following pages to see just how that works out.

NVIDIA Launches Maximus 2.0, Combining Kepler and Tesla

Subject: General Tech, Graphics Cards | August 10, 2012 - 05:34 AM |
Tagged: tesla, quadro, nvidia, maximus, kepler, gk110

At SIGGRAPH 2012 NVIDIA announced a refresh of its Maximus workstation platform technology. Maximus is a technology aimed at professionals that work with simulations or content creation and editing. The updated platform features a Tesla K20 accelerator card as well as a Kepler-based NVIDIA Quadro K5000 graphics card. The K5000 in particular has 4GB of GDDR5 memory on a 256-bit bus and 1536 CUDA cores. NVIDIA states that the Quadro graphics card has 2.1 Teraflops of single precision compute power and draws 122 watts.

The K20 on the other hand features a GK110 Kepler GPU with Dynamic Parallelism and Hyper Q features that reportedly enable more than 1 Teraflop of peak double precision performance. Unfortunately, we do not know much more than that on the new K20 Tesla card as the exact specifications are still listed as “to be announced.” It is slated for a Q4 2012 release.

The Quadro K5000 workstation GPU

Beyond the hardware itself, the company’s Maximus platform has received software support from several high-profile software companies and system integrators. Some of the companies that certify and support Maximus are Adobe, Autodesk, Mathworks, and Paradigm among others. Dell, Fujitsu, HP, Lenovo, and Supermicro are OEMs that support the hardware and manufacture Maximus-powered workstations.

The second-generation Maximus technology will be available in desktop workstations as early as December 2012. Further, the NVIDIA Quadro K5000 will be available for purchase as a separate discrete card in October 2012 for $2,249 (MSRP). The Tesla K20 will (for now) only be available integrated in a workstation, but NVIDIA lists the MSRP at $3,199.

More information on the NVIDIA Maximus refresh can be found in the company’s press release.
