ASUS ROG MARS 760 4GB Dual GPU Graphics Card Review

Manufacturer: ASUS

A slightly smaller MARS

The NVIDIA GeForce GTX 760 was released in June of 2013.  Based on the same GK104 GPU as the GTX 680, GTX 670 and GTX 770, the GTX 760 disabled a couple more of the clusters of processor cores to offer up impressive performance levels for a lower cost than we had seen previously.  My review of the GTX 760 was very positive as NVIDIA had priced it aggressively against the competing products from AMD. 

As for ASUS, they have a storied history with the MARS brand.  Typically an over-built custom PCB with two of the highest end NVIDIA GPUs stapled together, the ASUS MARS cards have been limited edition products with a lot of cache around them.  The first MARS card was a dual GTX 285 product that was the first card to offer 4GB of memory (though 2GB per GPU of course).  The MARS II took a pair of GTX 580 GPUs and pasted them on a HUGE card and sold just 1000 of them worldwide.  It was heavy, expensive and fast; blazing fast.  But at a price of $1200+ it wasn't on the radar of most PC gamers.

Interestingly, the MARS iteration for the GTX 680 never occurred and why that is the case is still a matter of debate.  Some point the finger at poor sales and ASUS while others think that NVIDIA restricted ASUS' engineers from being as creative as they needed to be.

Today's release of the ASUS ROG MARS 760 is a bit different - this is still a high end graphics card but it doesn't utilize the fastest single-GPU option on the market.  Instead ASUS has gone with a more reasonable design that combines a pair of GTX 760 GK104 GPUs on a single PCB with a PCI Express bridge chip between them.  The MARS 760 is significantly smaller and less power hungry than previous MARS cards but it is still able to pack a punch in the performance department as you'll soon see.

The ASUS ROG MARS 760 Graphics Card

The first thing you'll notice on the ASUS ROG MARS 760 card is its slick design that continues with the red and black theme of the ASUS Republic of Gamers brand.  The black is a soft-touch rubberized paint that is comfortable hold though obviously you won't be handling it very often.

Specification wise, the new ASUS ROG MARS 760 is a pretty impressive with 2,304 total CUDA cores and a base clock speed of 1006 MHz.  Of course, this all comes with the caveat of SLI - getting the maximum performance capability out of a dual-GPU configuration, whether it's on a single card or a pair of cards, is always much harder than with a faster, single GPU.  We'll talk more about that as we go through our benchmarks, but be sure you keep that in mind.

The MARS 760 is a dual slot design which means it should have no problems fitting in just about every case and system out there.  The DirectCU II cooler combines a pair of fans along with a pair of separate heatsinks to independently cool each GTX 760 GPU.  Each cooler users four heat pipes to distribute the thermals from the pad to the fins.

On the back of the MARS 760 you'll find 16 super-low noise POSCAPs that are made to enhance stability and power delivery for stock use as well as overclocking.  The plate on the PCB is both functional and aesthetic.  It looks good while supporting the cards length and weight when installed. 

ASUS' custom PCB uses a 10+2 phase DIGI+ digital VRM solution - 5 phases for each GPU and 1 for each pool of 2GB of memory.

The output configuration is unique on the MARS 760 with a set of three dual-link DVI outputs and a mini-DisplayPort as well.  This will definitely be advantageous for most buyers as DVI monitors are still the most common connectivity type.  The mini-DP connection means you'll also be able to support 4K panels if you want to as well.

The power requires a pair of 8-pin connections which isn't outside the boundaries of other high end, custom graphics cards.

Even better news is that ASUS and NVIDIA are allowing for quad-GTX 760 support if you want to pair the ASUS ROG MARS 760 with yet another ASUS ROG MARS 760.

This thing would be amazing with 4gb for each GPU at $600.00. That's where it needs to be for success.

I have to say that as impressive as this card seems, the only value it has is in it's compact design. You are paying for it's size, not it's capabilities. For around $600, (a bit more though) you can get 2 GTX760 with 4Gb memory each and put the bacplates on yourself. Remember, the memory on SLI setups doesn't stack so the Mars doesn't actually have 4Gb of effective memory. I had 2 4Gb 760s in SLI for around the price this card sells for and was very impressed as they outperformed the 780! Now that you can get a 780 for around $500 and a 780TI for around $700, why would you want the middle? Save a couple hundred with the 780 and have great gameplay or toss a couple hundred more out there for the TI and beat a Titian's back side!

MadeLoveToByASUS is my screen name on the PCPER Podcast because I've never been "F*CKED" by ASUS. They always amaze me with the quality and performance of their products. ASUS is the best in my book and will remain there as long as they continue the path they're on. Love the card, but I have 2 ASUS 780ti's via SLI in my system and it rules all I've ever had. Keep it up ASUS and PC PER. You are both the best.

Heyyyyyy, is that a shot at my username

im assuming its like the 690 though and only 2gb are usable?

December 17, 2013 | 11:49 PM - Posted by Ryan Shrout

Well, it's 2GB per GPU.  Its ALL being used, just by separate GPUs.

Where's the custom 290 review ? =P

Thank you :)

my guess is that Asus didn't know Nvidia was going to release the 780ti...and they already had this card in the pipeline. If the 780ti didn't exist, this would be a sweet card.
Too late, Asus...good luck selling these things.

cool card but... 2 760 are not worth that much, if would be a perfect card if it used the full gk104 (770)... also 2GB per 760 is not so great considering the level of performance it can achieve without the vram being a bottleneck...

so yes... 2x 760s if you have a MB with enough space is a much nicer deal.

still, a cool card.

Hi PCPER thanks for the review... I am wondering how 2 of these cards would work in quad SLI. I haven't seen any benchmark numbers anywhere yet... Plus I haven't seen any available yet to buy? Any ideas when or where to buy them?

dear Sir,

we do have required laptop Core i5 with 4 Gb graphic card.
