OK, so I've been trying to figure out a way to describe the problem with DXOMark that even a Nikonian can understand. So I decided to try a car anology.
We take two guys, Soichiro Canon and Carol Nikon, with nearly identical old sports cars. They both have 1 liter engines and they take their cars to two testing services to see which one is better. Now the first testing service Displacement eXamination Organization, measure the displacement of their cars and gives them both a DXO Mark of 1. The second testing service Horse Power Review (hpReview) gives them both a score of 60. So they take their cars out to the track, and they perform almost identically. Now Soichiro Canon's and Carol Nikon's friends all go of course they performed the same look both DXOMark and hpReview gave them the same rating.
So, to Soichiro Canon and Carol Nikon, take their cars and put larger 1.5 liter engines in them, again they both get the same 1.5 DXOMark, and hpReview both rates them at 75, and again on the track they are the same. And the friends all point to the DXOMark and hpReview scores in their blogs and say of course they perform the same.
So, to Soichiro Canon and Carol Nikon, take their cars and put larger 2 liter engines in them, again they both get the same 2 DXOMark, and hpReview both rates them at 100, and again on the track they are the same. And the friends all point to the DXOMark and hpReview scores in their blogs and say of course they perform the same.
So, this time Soichiro Canon leaves the same 2 liter engine in the car, but, optimizes the intake manifold, adds fuel injection, balances the engine, increases the redline to 9000 rpms, and adds a free flowing exhaust. Carol Nikon puts in a 4 liter engine. Now they take their cars in for testing. Canon's car gets the same 2 DXOMark and Carol Nikon gets a 4 DXOMark. hpReview gives Soichiro Canon's car a score of 237 and Carol Nikon's car a score of 210. They take their cars out to the track and Soichiro Canon's car actually performs a little better. But, Carol Nikon's friends all exclaim in their blogs how much better Carol Nikon's car is because it got a DXOMark of 4, but, Soichiro Canon's car only got a DXOMark of 2, and everybody wants a car just like Carol Nikon's. Soichiro Canon's friends blog about how the Soichiro Canon's car was actually faster, but, generally are dismissed because the DXOMark had predicted performance so well in the past, and the hpReview is much more subjective, they also are reminded that Carol Nikon's car has way more torque.
So again Soichiro Canon and Carol Nikon take their cars back and work on them. Soichiro Canon increases the stroke of his existing 2 liter engine, so now it is a 2.2 liter engine, and Soichiro Canon adds a supercharger, an even better intake, and exhaust. Carol Nikon is annoyed that Soichiro Canon's car was better and puts in a 7 liter engine. They again take their cars for testing. Soichiro Canon's car gets a DXOMark of 2.2, and an hpReview of 500. Carol Nikon's car gets a DXOMark of 7 and an hpReview of 500. They take their cars out to the track, and Soichiro Canon's car being lighter wins again. Now, Carol Nikon's friends again blog about how much better Carol Nikon's car is because it got a DXOMark of 7, and Soichiro Canon's car only got a 2.2. Soichiro Canon's friends blog that DXOMark isn't accurate. Carol Nikon's friends retort what are you saying DXOMark is in bed with Carol Nikon? You felt that DXOMark was accurate before. Soichiro Canon's friends point out that Soichiro Canon's car actually won in a real world race. But, again Carol Nikon's friends point to the DXOMark of 7 that Carol Nikon's car got, and the 2.2 DXOMark that Soichiro Canon's car got, and proclaim that Carol Nikon's car is better. Soichiro Canon's friends just shake their head and know that Carol Nikon's friends just aren't going to get it.
Soichiro Honda and Carol Shelby.
And I'll end this with a quote from Soichiro Honda
`The value of life can be measured by how many times your soul has been deeply stirred.'
