The GDP of Russia isn't the PPP GDP of Russia. Internally Russian service and extraction sectors are cheap, which means intenrational PPP adjusted it is high. The GDP and non exports are much lower than Germanies and the indicator GDP PPP isn't that great to compare to the EWR.
Per person not too much changed, but the PPP GDP changed. However if it enables increase of productive facilities is an open question. If the service wage of a country decrease then that country will gain a short term boost in PPP GDP (till low income spending of service workers turn up in the statistics).
