Intel Core i7 8700K 6-Core Coffee Lake And i5 8400K Spotted in SANDRA
Intels upcoming Core i7 8700K 6-Core Coffee Lake And i5 8400K processors have been spotted in the SiSoft SANDRA database, meaning we have some new numbers to compare.
The scores spotted by hothardware are the Core i7-8700K with its 6 physical cores and 12 threads shows its scores against a Core i7 7700K:
- Processor Arithmetic: 217.98 GOPS (versus 149.99 GOPS)—45 percent increase
- Processor Multi-Media: 658.57 Mpix/s (versus 447.76 Mpix/s)—47 percent increase
- Processor Cryptography: 10.47 GB/s (versus 9.34 GB/s)—12 percent increase
- Scientific Analysis (Single Precision): 61.41 GFLOPS (versus 48.51 GFLOPS)—26 percent increase
- Scientific Analysis (Double Precision): 32.11 GFLOPS (versus 24.40 GFLOPS)—32 percent increase
Then there is the Core i5-8400K, also a 6 physical cores processor but lacking Hyper Threading (compared to a Core i5 7600K).
- Processor Arithmetic: 145.05 GOPS (103.66 GOPS)—40 percent increase
- Processor Multi-Media: 420.54 Mpix/s (279.69 Mpix/s)—50 percent increase
- Processor Cryptography: 9.78 GB/s (8.45 GB/s)—14 percent increase
- Scientific Analysis (Single Precision): 71.68 GFLOPS (51.38 GFLOPS)—39 percent increase
- Scientific Analysis (Double Precision): 31.35 GFLOPS (26.72 GFLOPS)—17 percent increase
Coffee Lake shows around a 32 percent improvement die top the two extra cores.

Because the 7800x is a flop at gaming. Getting beaten by the 1500x is some games. The die is an 8 core conected by a ringbus and two cores are dissabled. This is causing latency issues between cores. Leading to issues with gaming performance.
The 7820x does not have this issue BTW.
That 50% increase is in multithreading performance - I think single-threaded performance increase is about 10%, some of it due to higher clock speeds. Unless you run a lot of multithreaded apps, a 8700K won't add much over a 7700K. Also, based on leaked pricing from a Canadian retailer, the 8700K looks to be priced about the same as a 7800X, which is also a 6C/12T CPU. In other words, a mainstream 6-core Intel CPU is already here, it's just that people don't talk about it for some reason.
