So, 2 of the boost OC models in SLI? is that going to be the new "best bang for your buck?"

For the OC card, this overclocked combination cranks out 30-percent increased performance in DirectX 11 benchmarks, and 40-percent better performance in PC gaming than the baseline GTX 650 Ti Boost model.

So a ~1% overclock yields a 30-40% increase in performance? I find that rather hard to believe, but if it's true, that's some pretty sick improvement for such a mild overclock.

If you read further down...

ArticleWith a wider 192-bit memory interface and up to 60 percent more memory bandwidth than the original, the GeForce GTX 650 Ti Boost GPU lets gamers play their favorite games at 1080p at high-quality settings with smooth frame delivery and comfortable frame rates for even the most graphically demanding games on the market today, including Crysis 3," Nvidia said on Tuesday.


So it has memory clocked at 6 GHz instead of 5.4 GHz on the regular 650 Ti, and on a 192-bit memory interface instead of 128-bit. Which means it has a memory bandwdth of 144.2 GB/s compared to 86.4 GB/s on the regular 650 Ti. It also has 24 ROPs instead of 16, and had a boost clock about 100 MHz higher than the base clock of the regular 650 Ti. It has a pixel fill rate of 23.5 Gpixels/s compared to only 14.8 Gpixels/s... So i would believe the 30-40% increase in performance, it's alot more than just a "~1% overclock"

All 650ti Boost cards are specified to have a 192-bit memory interface. It's the standard 650ti that has a 128-bit interface.

Nevermind, you're right! My mind read it as "baseline 650 Ti" and blocked out the "boost", because that obviously couldn't be right! There is absolutely no way that Palit's card is 30%-40% faster than a reference 650 Ti Boost, i've heard of manufacturers claiming unrealistic performance increases but that would be just ridiculous.. Yeah, thats about a ~1% overclock alright.. Must be a mistake, I guess it should be saying it's 30%-40% faster than a standard 650 Ti.

Yeah. I'd expect 30-percent improvement over a standard 650ti from any 650Ti Boost card. But, as I said, if a 1-percent OC to a 650ti Boost yields 30- to 40-percent over base model Boost cards, that's just insane bonus performance. No person in their right mind who wants to game on a budget would bother buying a base model card. That, or they'd be crazy not to OC one.

From a manufacturer's standpoint, it would little sense to produce two versions of the card if their performance varied that much. Seriously, 30- to 40-percent increases in performance is what you see when you step-up in series, like going from a GTX660 to a 660Ti.

To be fair, I can't recall seeing a PC component jump in performance like that due to an overclock since the days of the Slot-1 Celerons and Pentiums, where if you were able to change the FSB from 66Hz to 100Hz on an Intel 440BX motherboard, you could turn a 333Mhz CPU into a 500Mhz one. Good times back then...

It's roughly some 3.8% improvement of GPU clock and 1.6% for memory, my guess is that mr Parrish added those 0s and that improvements are 3% in DX11 synthetic tests and 4% in games.
