True, unless you're comparing the same chip. But since the nodes are similar in size, and GP104 is larger than Polaris 10, you would think that GP104 would use slightly more voltage... but it doesn't... and it clocks much higher... so...

if big (biggest) Vega beats Titan P fair and square then I will go Team Red thumb.gif

Actually we are using Transistors not resistors, the effect of voltage is different. The power draw can be calculated much better by transistor leakage current (for power calculations during idle) or how often transistors are switching (for power calculations during calculation).

Voltage is very non-linear with transistors. There is almost no effect on voltage until you hit the transistors activation limit, which depends on transistor design and size. Beyond that voltage the scaling become more in line with Kirchhoff's laws.

No I will bash you for being clueless. See, I'm getting an early lead thumb.gif

Its probably just a slightly oc'd 970 aib card. Not manually, +400 card.

So, do you think my assumptions might be correct?


RX 480 will trade blows with 970, both stock vs stock and oc'd vs oc'd, in dx11 games.
RX 480 will trade blows with stock 980 in dx12
RX 480 will lose to 980 oc'd vs oc'd, both in dx11 and in dx12

we'll see tomorrow

frankly that's not even my option for a GPU, but there's been so much hype for Polaris architecture that I wanna see how it performs, even if we get a $200 card first

will definitely win in AotS and Hitman, other DX12 idk

we wont even know how well it OCes until the "beast mode" cards surface

Just so were clear I actually bought ashes and just didn't like it, unlike Chev who just bashes for the sake of bashing.

Seems legit, here I was thinking I missed somekind of news about it. smile.gif

Well you can at least give AMD bonus points for understanding what MSRP means

And yet you have a 'resistor' (collector-emitter resistance).
It may be negligible if you have a couple of transistors, but not if you have billions, and high switching frequency
