Coffee is Refreshing, if it is authentic

Geekbench leaks are pretty common, and often at least a wee bit photoshopped so don't take the performance numbers leaked out as fact but there is a slight possibility they are based in reality.  The i9-9900K is shown with a score of 6248 points in single core and 33037 in multicore, while the i7 part reached 6297 and 30152 respectively.  The logic holds somewhat as the i7-9700K is 100MHz slower than the i9 but has half the threads as it is not multi-threaded.  These numbers are higher than Ryzen 2 in single threaded performance but fall behind on multi-threaded apps; as has been historically the case.  

Grab your salt shaker and head to WCCFTech for more details on these two chips as well as the i5-9600K.

"Geekbench 4 benchmarks for three next-generation Core processors popped up early according to the folks at WCCFtech, with the chips so far look to be mild refreshes on the current Coffee Lake S generation of processors."

Leaked Geekbench Results: AMD Zen Performance Extrapolated

Over the holiday weekend a leaked Geekbench benchmark result on an engineering sample AMD Zen processor got tech nerds talking. Other than the showcase that AMD presented a couple weeks back using the Blender render engine, the only information we have on performance claims come from AMD touting a "40% IPC increase" over the latest Bulldozer derivative. 

The results from Geekbench show performance from a two physical processor system and a total of 64 cores running at 1.44 GHz. Obviously that clock speed is exceptionally low; AMD demoed Summit Ridge running at 3.0 GHz in the showcase mentioned above. But this does give us an interesting data point with which to do some performance extrapolation. If we assume perfect clock speed scaling, we can guess at performance levels that AMD Zen might see at various clocks. 

I needed a quick comparison point and found this Geekbench result from a Xeon E7-8857 v2 running at 3.6 GHz. That is an Ivy Bridge based architecture and though the system has 48 cores, we are only going to a look at single threaded results to focus on the IPC story.

Obviously there are a ton of caveats with looking at data like this. It's possible that AMD Zen platform was running in a very sub-optimal condition. It's possible that the BIOS and motherboard weren't fully cache aware (though I would hope that wouldn't be the case this late in the game). It's possible that the Linux OS was somehow holding back performance of the Zen architecture and needs update. There are many reasons why you shouldn't consider this data a final decision yet; but that doesn't make it any less interesting to see.

In the two graphs below I divide the collection of single threaded results from Geekbench into two halves and there are three data points for each benchmark. The blue line represents the Xeon Ivy Bridge processor running at 3.6 GHz. The light green line shows the results from the AMD Zen processor running at 1.44 GHz as reported by Geekbench. The dark green line shows an extrapolated AMD Zen performance result with perfect scaling by frequency.
