HEXUS Bang4Buck and Bang4Watt
The performance benchmarks on the previous pages tell part of the story, but it is also interesting to see how CPUs compare once value and power efficiency are put into the equation.
We have taken both single- and multi-threaded applications in the form of PiFast and Cinebench and then calculated how the CPUs line up once launch price is factored in. We also graph up single- and multi-threaded relative performance with the TDP factored in, hence a bang4watt for both workloads.
Looking at lightly-threaded applications first, the speedy chip's metric doesn't look so good because it is difficult to get around that $599 price. The bang4buck is still better than a Ryzen 7 1800X because while the Intel chip is 25 per cent more expensive, it is faster by more than that margin.
Taking the manufacturer-quoted TDP into account, 140W and light loads don't mix well, hence the performance coming near the bottom of the graph.
Really, one needs to pay closer attention to the metrics for all-core Cinebench. The Core i7-7820X has decent performance and a reasonable price tag, for Intel at least. What the bang4buck graph shows us is that AMD continues to hold sway here because the Ryzen multi-core performance and keen pricing combine well to beat Intel. The review chip is faster than Ryzen 7 1800X but its 20 per cent price difference is larger still.
We're happy to see Intel's HEDT chips at last provide decent numbers in these graphs.
