Wow adoredtv video is simply amazing! It prompted me to follow up on how i5 2500K vs PD 8350 performance developed during last 4 years.
Originally , as adoredtv showed, i5 2500K had around 17%(!!!) percent advantage over 8350 with GTX680 in late 2012 when tested at super low 480p resolution. Logic behind this , like today in Ryzen reviews, is that lower resolution (today's 1080p is yesteryear's 480p) is going to show us how present day CPUs will cope with next gen GPUs in years to come. All makes perfect sense, doesn't it. Lets see.
Fast forward 9 months later, to June 2013, same computerbase did tests, this time with GTX Titan (GK110) (around 35% faster GPU than GTX680), that lead 2500K had over 8350 at 1080p, which was 10.4% has fallen to 8.5% in 2013. Even the difference in 480p super low res. has fallen from 17% to 14% with more powerful GPU! Hmm maybe a fluke result? Lets see what adoredtv found out next.
FFW to 2015 BDW 5775c launch, same computerbase website. The site used the same GPU (Titan GK110) so relative difference between 2500K and 8350 remained the same, no surprise.
FFW to 2017 - the Kaby Lake launch and computerbase's article that covered that. That is
5 years from the original date used in the video for perf. comparison between two popular desktop CPUs: 2500K and 8350. Computerbase used 8370 this time in their article this time as it substituted the original FX8350, but the difference is negligible and is only 2.3% and only when ST is used(base is the same). They used the same GTX Titan GK110. The results? Well, 2500K is 8.2% faster than 8370, same situation as before.
FFW to present day and a week before Ryzen launched. Computerbase updated their gaming test suite and are now using more modern games coupled with an update to more modern GPU in their testbed:
GTX Titan X Pascal (the fastest card to date). This should help show that potential 2500K had 5 years back when it had 17% lead over 8350 Piledriver in super low res. 480p gaming - this was specifically done in order to "simulate" how the chip will age with time and how will it handle more modern GPUs and more advanced games.
The results? Today,
FX8370 is 10% faster than 2500K in 1080p when tested in latest games, with fastest to date GPU. Even in 720p 8370 is over 10% faster than 2500K!
That is a Bulldozer derivative "8core" chip leading (much) higher IPC 4C/4T Sandy Bridge core in 1080p and 720p gaming, coupled with fastest GPU to date in modern games
!
4C/4T is low? Ok, 2600K is just 6% faster than FX8370 in 720P!
Today we can see a similar trend:
4C/8T even though near the top is slowly starting to fall back. In next 2-3 years this trend will continue and all that invested in KL 7700K will see their almost 400$ chip eating dust of Ryzen and BDW-E, SKL-X and Coffey Lake 6C+ chips. This WILL happen and people ought to be aware of this now before they make their purchase decisions.
