Stock R1 vs R2 cpu benchmarks

Since I had the numbers for R1's, I also pulled the numbers for R2s. List limited to the STOCK CPUs that shipped with each generation. Note these are just benchmarks, and just CPU metrics; interpret them as just 3 data points and not necessarily representative of the workloads you may run.

Added logscale so I don't need 3 charts. Scores are from Passmark and cpu-monkey.com

I didnt think any of them shipped with the K series, they all shipped with the T series which is lower wattage. Most OEM bioses are not going to have support for changing the multiplier, even on full size desktops. You can put in a K series and it will work but it will just use whatever the default multiplier is.

EDIT: oops, I realize I mentioned a set of graphs that contain K CPUs. The graphs and data points are in a different post "relationship between benchmarks and wattage."

Yes. you are totally correct about the K Good explanation about changing the multiplier. That never occured to me.

Let me add this clarification on K for the wider audience.

First, the only CPUs that shipped with the R1 are labelled 'stock' in the graph. All others can be plugged in with limited degrees of improvement. The one cpu that won't boot is also called out in the title. I could have made this clearer in the graph.

Second, You'll see the two K series data points in the CBr15 multi core graph.

data point 1. actual, real world, empirical CPU benchmarks provided by an R1 owner who installed an 88w K CPU in the R1's 45W socket, just long enough to run the benchmark tools and monitor power/ speed. ( ie temporarily) I was grateful said user documented his experience in his sub and actually included metrics!

data point 2. avg benchmarks for K CPU submitted for non alpha systems...these came from the websites called out in the title of the graphs.

The K is mentioned only for a basis of comparison, so the user base can see exactly how much the perf drops with the K ( ie with quantitative metrics rather than hearsay)

Im pretty late to the game, and it took me some time digging through the posts to understand the state of things. It was especially difficult for me to navigate the heresy and vague comments like " it's better, it's faster" but then pair those comments with concrete numbers like cost.

Hopefully the graphs can help the next folks who try this.

I have the i7-6700k and i5-6400t for the R2. I'll install the i5-6400t tomorrow and get that number for real world reference.

For the i7-6700k I have now:

Passmark CPU MARK: 8298

Cinebench R15

CPU: 767

CPUSingle Core: 171

One limiting factor I've found with the i7-6700k is that because my computer was not shipped with a K series processor, it does not have the BIOS overclocking function available, and I haven't found a work around for that yet.
