When one sees benchmarks in the PC space, we don't use vendor specific software solutions to compare between hardware so the same precedent should apply to game consoles and thus exclusives should not be permitted for hardware comparisons since it skews perception without objective analysis of measuring code execution performance ...
Using the PC as an example in that context is a little disingenuous.
A game ported to the PC is generally optimized primarily for the software ecosystem, like the API's and other eccentricities of the platform rather than any individual hardware piece.
A console game is generally taken a step farther than that, more of the non-standard functional capabilities of the hardware is leveraged to eek out more performance or add new effects. Not always. But more often than not.
Case in point... The Xbox One's GPU is roughly comparable to a Radeon 7770. But the Xbox One will always be able to outperform it when developers leverage the eSRAM for deferred render targets, if that GPU existed on the PC, no developer worth a pinch of salt would bother with such a scheme.
100% agree, it's the same for digital foundry, except in rare cases, they compare GT VS forza, where it's works considering both games are going for the same exact thing, it also helps that were dealing with facts, exclusives are usually based on '(My preferred company of choice) looks better, and is technically more demanding than (the competition)'.
Comparisons can always be made.
But the more the two apples begin to differ, the more components you need to take note of in said comparisons.
I mean... Take a game like Gears of War and compare it against Borderlands.
One is Cartoony... And one goes for a stylized realistic approach, in short they are completely different artistically.
However... They share much of the same technology and in most scenario's would probably be relatively equivalent in hardware demands all things considered.
while of course switch games that are technically more demanding, the best of ps3 is uncharted 3, and the last of us, would love to see something that looks good on switch at 1080p/30fps, well that's if you prefer realistic graphics.
Take note of when those games launched on the Playstation 3.
And then take note of when the Switch released.
Resolution and framerate isn't everything there is about graphics/performance/hardware capability.
