I was quite curious about the OpenCL performance of these latest cards. AMD has really been pushing OpenCL as of late, especially in advance of the release of the Kaveri APUs. They have a pretty solid OpenCL 1.2 implementation for their GCN based chips. NVIDIA of course has been blowing the GPGPU horn as loudly as possible over the years and focused on CUDA. Oddly enough, Kepler made compute performance take a back seat to enable better performance and efficiency in graphics applications. I used the 64 bit version of Luxmark 2.0 with the Sala test.
Yeah, that ain’t pretty. The GTX 780 is slower than the 270X when it comes to this particular OpenCL application. It looks as though the upcoming Maxwell architecture improves GPGPU/OpenCL type performance to a pretty large degree. Unfortunately for the GTX 780, it is not based on the Maxwell architecture. The Kepler architecture does some things very well, but this type of computing is not one of them.
You state power limit
You state power limit increases for bios #2.
But what are they?
But don’t state in your overclocking page which you used.
While I presume you are using #2 bios, you said the power target is different, could you tell me the actual power target limits?
More curious than anything..
Getting exact numbers for you
Getting exact numbers for you on power target. Can tell you that fan speed for normal is 30% to 85%, but with the 2nd BIOS the range is increased from 20% to 100%.
The power target goes up to
The power target goes up to 302W (up from 295W).
But the most important
But the most important question is: Does this have the Double Floats wanted by the Miners? Will this card’s price be shot through the roof for no particular reason?
Nope, you need a Titan to get
Nope, you need a Titan to get those kinds of numbers.
oh, and Josh, Ryan, you’ll
oh, and Josh, Ryan, you’ll need to know that I found out about this article from your (Josh) twitter mention of it.
Remember everyone that this
Remember everyone that this is a review of the EVGA GTX 780 and not the EVGA GTX 780ti so the price is lower than that of the EVGA GTX 780ti.
The EVGA website price for the EVGA GTX 780GTX with ACX is 499 US dollars.
The EVGA website price for the EVGA GTX 780GTXti with ACX is 709 US dollars.
I don’t foresee the price of this model being reviewed increasing anytime soon unless EVGA decides to do so.
The dual BIOs allows you to overclock one BIOs and if something bad happens you can switch to the 2nd BIOs.

I have just installed this
I have just installed this card, and the part about running faster than the stock speeds is true for mine as well. It runs consistently at 993mhz, which just happens to be the 780SC stock speed, so I’m pretty happy with the results. Like a small upgrade for free.
The fact that I’ve had two 680ftw cards that ended up being duds, running hotter every week until they blew up, I’m surprised I bought yet another EVGA product, but the author is right; no one else coddles the purchaser like EVGA. No questions asked, and in fact, they saw what I’d done by looking at my comments/actions via the Forum, and didn’t have me dance through hoops for an RMA. I also like their upgraded RMA system, where you just get a number and give them your CC# to hold, and they send you a new card that day. Once you get the new card, you just put the old one in the package, tape it with the RMA sticker, and you’re gaming in a couple days instead of weeks.
This is reference PCB design
This is reference PCB design just has bios switch and does not offer any addition extra power phases
There is no difference between this and standard 780 other than having 2 BIOS out of the box 2nd BIOS offers no advantages over the other.
The 2nd bios so in case you have issues you have another bios to fall back on
Direct from EVGA… 2nd BIOS
Direct from EVGA… 2nd BIOS offers increased fan speed control and a 8 watt increase in power. Compare pics of the back of the card from original GTX 780 reference design. Some significant differences there.
He/She is correct it uses the
He/She is correct it uses the same reference PCB it just has added bios switch.
The FTW and Classfied use non reference PCB
Direct from EVGA, this would
Direct from EVGA, this would not be considered a reference design. *shrug* take it as you will.
also 2nd BIOS didn’t do much
also 2nd BIOS didn’t do much at all to help OC
I end up flashing custom BIOS that disabled speedboost and higher power target and unlocked voltage to 1.212
EVGA is the BEST COMPANY IN
EVGA is the BEST COMPANY IN THE BUSINESS. PERIOD. Kingpins team in also the best in the business which is no coincidence.
EVGA FTW or GTFO.
