1429 MHz Boost overclock on the Palit GeForce GTX 750 Ti StormX Dual

[Slomo4shO]

Guru3D's review of Palit's 750Ti offering was able to yield an impressive boost frequency of 1429MHz on a card that has no 6 pin adapter...

I wonder when/if there will be voltage unlocked versions of these cards...

Maxwell arch is looking pretty spiffy.

Scaling looks pretty average, nothing special. Do they know if the card maintained that boost throughout the benchmarks.

 

[Arkadrel]

so its stock speed is 1020 mhz, but this one overclocked to 1429mhz
(40% overclock).

In turn it beat stock 265 in performance.

Still pretty darn impressive.

^ agree'ed was not expecting this much improvement with new architecture.
The perf/watt increase is insane.

The engineers behinde this monster should be right proud of their work.

Reference boost is actually 1085MHz so it would be a 31.7% OC

Isn't it still hitting it's TDP limit? If the power limit could be exceeded past the locked 100% setting, it'd probably scale better.

My 650m can overclock crazy high but I don't because of power constrains.

If the normal is 1085, then this 1202mhz one is only running +117mhz.

But it uses:

69 watts (instead of 52watts).

So yes a card at 1429mhz would probably be over ~100 watts.


Still even at that high a overclock, its perf/watt wouldnt be half bad.

For a 30% overclock, the scaling isn't looking so strong... probably a result of the rather limited memory bandwidth. This thing might do so much better with a larger memory bus.

Even totally disregarding any overclock, this does well at stock. Especially at 52W and without the need for a PCIe power connector.
As for a comment earlier, is the card even capable of pulling 100W from the 75W supply of the PCIe bus? or can it deliver far more than 75W?

75W is more of a "specification" limit than a physical one. The slot can probably deliver a lot more than 75W, but it isn't guaranteed to do so safely/properly/reliably.

Strange that 750Ti uses less power than 750 (non ti)...

Whadya mean?

What I meant was from the Anandtech review: http://www.anandtech.com/show/7764/the-nvidia-geforce-gtx-750-ti-and-gtx-750-review-maxwell/23

"The first is that the power target is limited to 100% on all cards. Because these are sub-75W cards, NVIDIA is not allowing anyone to exceed the card’s default TDP."

It looks like this card is exceeding the 100% power limit in the review though.

here is direct GPU power consumption comparison:

It's o/c'd bud. So there isn't much strange there.
Also could you link the source to the graph. thanks.

This architecture is looking just plain exciting all around.

If they were able to achieve this on 28nm, it isn't hard to extrapolate what that means for a 20nm process that is more efficient and allows greater density.

 

[Keysplayr]

Yes it really is. I mean the 750 Ti specs are a good margin lower than the 650Ti Boost and right around the speed of it.

650Ti Bst vs 750Ti

192bit vs 128bit
768sp vs 640sp
104W vs 52W <--- Holy Moly...

It looks like a taste of some very good things to come in Maxwell series.
