Thinking about the 8600K - Page 2

post #11 of 49
If leaks are true, then I don't see the 8700K beating fair square the R7 1700 at anything that is not cherry picked. I mean, that would be only possible if Intel somehow managed to get over 17%+ ipc, which is very unlikely.

The 7700K has a 30%ish single core clock advantage over the R7 1700, but only manages to get 33% higher score with single core on Cinebench R15.

i7 8700K totals 25.2GHz at stock

R7 1700 totals 28.8GHz at stock

Also, the R7's do scale well in most MT applications.

Anyways, If Intel somehow manages to get that a 15% IPC increment then some Core I7 7800X and 7820X owners would be very, very upset.

Have you checked gaming+streaming benchmarks of ryzen vs intel? Ryzen loses less fps from streaming even compared to 8 core intel.
In case of 8700k vs r7, i think intel will do better in gaming but streaming ryzen may win, or maybe it depends on games you stream.
8600k vs r5 i think ryzen will be winner for streaming.

It only applies in near perfect MT programs.

I'm still confused on how a CPU totals that clock speed. You don't add the clock speed of the individual cores. That isn't how processing works.

While that's not exactly how MT scales you can paint a good picture about the future.
Coffee Lake ? 5+ IPC at best, and I'm not talking about the kind of 5% that sums to 50% after ten generations if you know what I mean.

I don't know what you mean. You pulled random numbers out of this air to illustrate a point that's still vague.

The great thing about Coffee Lake has nothing to do with IPC gain. That will be negligible as it's just further optimized Skylake. The great thing is more cores across the entire lineup and better multi-threaded performance.

I feel the i7-8700K will just be i7-7800x with 4.7GHz all core on average (maybe with delid?), dual channel RAM, and none of the mesh architecture (so a i7-6700K with 2 extra cores).
The major advantage to the i7-8700K will be much cheaper motherboards.

Also the older Noctua NH-U14S & NH-D14 fit on the Asrock Z370 Taichi , Z370 Extreme4 , ASRock Z370M-ITX/ac .

edit: However, it remains to be seen how many boards will come with Thunderbolt rather than Thudnerbolt boards as an add-on. Asus Z270-A was a better deal because of it.

Wait for the launch and official benchmarks, you may figure it out.

I don't know bro, the 8600K is a hard beat... I think the 8700K is going to be what Intel should do instead of what Intel can do. People claiming 10, 20 , 25% IPC increase LOL. I think that saying it will beat clock for clock the R7 1700 at everything is...well, unlikely to say at least.
