nVidia announce the Titan X at GDC 2015

Mal X · 11 Mar 2015 at 11:03

i dont have access to a calculator, but it looks about 60% faster than a single 970....but slower than SLI 970, just !

but it's a single card only without the hassle of SLI, so the important thing now is its price.............plus of course the 390X

970 is easy tbh as the fps is 100 so it's 53.6 percent faster.

Nah even a quick dirty calculation means it's over 30 percent.

153 - 116 = 37

116 divided by 10 to get 10% is 11.6

11.6 x 3 = 34.8 which is 30% with just under 2 percent left over.

Yep

Assuming a baseline of 116.2 (ie 100%) the 980 would need to be 32.18% faster in order to match the Titan X base figure.

i.e 116.2 * 1.3218 = 153.59...

What on earth is that calculation?

You guys need to look up the difference between a difference and change

. Both formulae are correct but you use one or the other depending on the subject and context.

A quick and dirty is like Marine did it: 153.6 / 116.2 = 1.32

Actually your maths is wrong too . Although less wrong than Greg's .

You'd use the formula:

(X-Y)/((X+Y)/2)) * 100

So it's like 28% difference in value but your method is OK for a quick and dirty calculation.

Given a clear baseline (the 116 figure for the 980) you're just a straight (other_fps/baseline)*100 which gives 132% so 32% faster. If using the Titan X as baseline then it'd be ~25% slower by using the same calculation method, or the 980 is 75% of the speed as stated.

You can also use the formula ((other_fps - baseline_fps) / baseline_fps) * 100 if you want to get straight to the % difference, it is the same formula.

You're trying to avoid using a baseline but the sentence clearly stated it in reference to a value (that is our '100%') - it's very bad practise to ever try and use % without a clear baseline as it's at best ambiguous.

The only one with the wrong answer is you

. I was just trying to show you why you were wrong in an easy manner.

Marine-RX179 · 11 Mar 2015 at 11:17

lol seriously why are some of you guys turning a simply calculation into something much more complicated...and get the answer WRONG as well.

(Titan X)153.6/(980)116.2=1.32....

So the Titan X is 1.32 times the speed of 980...or the 980 is around 75% of the speed of the Titan X.

May be some of you need to try something simple, like how much more is £1.50 comparing to £1

Gregster · 11 Mar 2015 at 11:19

hmmmm, using my method.... The 980 gets 116.2 (lets call it 116 for ease) and the TX gets 153.6 (lets call that 154 for ease) and using my math methodology, that makes it **** loads faster than the 980, so on thew basis of my math:

Rusty0611 · 11 Mar 2015 at 11:20

It's pointless trying to explain it if you guys can't get your head around the difference between a difference and a change

. But, whatever

.

Is it 32% or 28%. Quite where you pulled 28% from lol. It would seem even when you are wrong you still think you are right and we need to get our heads round it.

It can be either depending on the context or subject. What it isn't is that abomination of a calculation you pulled

.

What my formula does is take he difference between the two values and divides it by average giving the percentage 'difference'. What the other formula does it work out the percentage change.

I've no problems admitting when I'm 'wrong' but I won't accept somebody who pulled something out his backside as a 'calculation' telling me I'm wrong

Ugghhhh Maths

I am off

Really? May be you can try using your method and tell us how much more is £1.25 comparing to £1 in %?

David Bisset · 11 Mar 2015 at 11:31

lol Marine, harsh

clearly the answer is 22% ... oh wait

*facepalms*

I've added a wiki link to my previous answer for Rusty if he wants to read up on how to do comparisons as percentages. With a reference point given his effort at a universal difference is not a meaningful value, had the sentence been written differently (it would have had to have broken the guidelines for how to express comparisons however) then his answer would have been valid - percentage difference is a legit thing, just not in this case (though it's an abomination and should probably never be used).

Everyone was saying the Titan x is 32% faster than the gtx980.

Nobody was saying the Gtx980 had 24% lower frames compared to the Titan Z.

I seen nobody wanting an average between the 2 stats.

As a quick working without a calculator or typing in google i just get 10% of the base number and work from there as a really quick way to get a quick number. It's usually accurate to 1% doing it quickly in my head.

Have a read and take your pick:

http://www.calculatorsoup.com/calculators/algebra/percent-change-calculator.php

I was tongue in cheek with my remark to you being 'wrong' (perhaps I didn't signpost it clearly enough) but I've no interest in arguing the nuances of the two methods to be honest.

Gregster · 11 Mar 2015 at 11:33

Come on chaps, let's not debate over figures we can all see.... Maybe you can help me out on a quick question that I can't seem to answer...

I have enough cash for 2 Titans howver, I am on quite an ageing system now with the 3930K. So would you get a single Titan, a 5930K/5960X (depending on what a single Titan costs), X99 mobo and DDR4 RAM or would you just keep the 3930K and grab a pair of Titans?

I keep going one way and then back again in my head.

triss · 11 Mar 2015 at 11:34

Can we at least agree Titan X is indeed faster then the last single one

2 titans X greg,, if ur x79 is rolling along fine keep it for a bit let X99 settle in price more IMO

I don't need a wiki link I work in an actuarial project at the mo. You guys

.

Anyway guys as I say zero interest in arguing over it so we'll agree to disagree.

Keep what you have and get 2 x Titans as that will give you much more Graphics power for the money. Your setup is still among the fastest out there.
