[WCCF] MSI GeForce GTX 780 Ti Lightning Strikes Thunder - Page 6

post #51 of 115
Overclocking is a pretty poor argument to make when it comes to the current AMD GPUs because that's actually their weak point compared to GK110. Taking overclocking into account only makes current Nvidia chips seem better comparatively.

Even my Titan has no problems beating overclocked 290X setups...

How about you don't make up stuff and pass it off as fact please.

I've run through Firestrike, Hitman, Metro LL and more at 7800 mhz. And there are plenty of Ti owners that have done much better in the bench threads.

780 Ti uses Hynix ram not Elpida and has no issues with decent overclock.

7800 mhz = 1950mhz GDDR5.... and i said most people can only get 200mhz on top of the 1750( 1750 + 200 = 1950).

R9 290x is clearly the winner when it comes to Vram, size and bandwidth. and i will never let Vram bottleneck my cards(again), id rather have a slower core only getting me 30fps, without the insane jitters that Vram limits bring.

and just incase your reply is "well not everyone overclocks", i beg you to look at what website you are on, and what thread this is.

EDIT: what i meant to say in my previous post was " No complaints here, go 290x lightning. Screw the 780 tiny vram, and bus width" forgot ", and"

refrences.

290x memory overclock http://www.tweaktown.com/tweakipedia/37/sapphire-radeon-r9-290x-tri-x-overclocked-power-consumption-numbers/index.html
780ti memory overclock http://www.bit-tech.net/hardware/graphics/2013/11/07/nvidia-gtx-780-ti-3gb-review/11

I have seen a lot of ti's exceed 7200mhz memory.

edit - i guess you meant 7800mhz which sounds about right. My 2 ti's do 8400mhz and 8600mhz.

Titan does not have the voltage restrictions, has 6GB Vram, costs 1000$.

That is not what you said. You said "best you can get is 200 mhz" which is incorrect.

Let's look at some of your claims with a thread from here at OCN.

The Firestrike bench off thread has 10 oc'd 290x entries of which the average is 1511 mhz.

It also has 8 oc'd 290 entries of which the average is 1495 mhz.

Same thread has 14 780 Ti of which the average is 1987 mhz.

Now I agree with you that the R9 series does indeed have the edge in bandwidth, there can be no argument there.

But the amount you claim vs the samples we see here by real users simply doesn't match.

i also said getting the 290x to 1550mhz gives it 422gb/s while 780 TI at 1950mhz has 374gb/s. which is not far off from ur numbers, 1987/1511. not even 50mhz difference in both cases. not sure if your trying adding to or disputing my claims.

I still wouldn't call either having a "tiny" bus or a "tiny" amount of bandwidth. wink.gif

I'm disputing your numbers respectfully because I need more proof than just one website example of each.

A stock 780 Ti runs at 7000 mhz.

7000 x 384 = 2688000 / 8 = 336 gb/s.

A stock 290x runs at 5000 mhz.

5000 x 512 = 2560000 / 8 = 320 gb/s.

These are the bandwidth numbers all the sites report so the formula must be right.

So let's look at overclocked.

780 Ti. - 7800 x 384 = 2995200 / 8 = 374 gb/s.

290x - 6200 x 512 = 3174400 /8 = 397 gb/s.

Where are you coming up with the 422 gb/s figure? It's simply not correct.

Also, if we use the memory averages found in the Firestrike thread from multiple samples from ocn members, the 290x edges the 780 Ti 386 gb/s to 381 gb/s.
