Value and Efficiency Tests
The performance benchmarks on the previous pages tell part of the story, but it is always fun to add some Bang4Buck metrics into the mix. Do be aware that there are many methods of calculating such results - different benchmarks will skew the outcome, and prices can both fluctuate daily and vary wildly depending on region.
We've chosen to use the multi-threaded Cinebench test as a basis for our results, and pricing was taken from Newegg.com on November 14, 2018.
This graph shows the Cinebench score divided by the price. Nice and easy. Note we've used updated procing for the 9th Gen Core range due to the aforementioned stock shortages. This is why the Core i7-9700K is so much worse than the AMD Ryzen 7 2700X.
We have also changed methodology here. Rather than take the manufacturer-quoted TDPs, we have chosen to ascribe the 2D system load figure - what we actually see - as the power reading.
This graph therefore shows the Cinebench score divided by this figure, so for the 9700K that would be 1,495/148, and so on.
What's interesting here is that the Core i9-9900K doesn't performance significantly better, even though it scores so much higher and has the same Intel TDP. It really doesn't, as reflected here.
We can also combine Bang4Buck and Bang4Watt for an overall weighted efficiency score. By taking 5.67 as the ceiling for Bang4Buck, and 15.00 for Bang4Watt, the weighted score shows the Core i7-9700K in a true light.
It's a good chip for multi-threaded applicatons, with good energy efficiency, yet that street price of $480 stifles its appeal.
