R7 1700 vs i7 7820X vs i7 6900K

I would have considered the 7820x if they priced it a little lower and didn't reduce pcie lanes. I don't even need a bunch of lanes right now but it would be nice going forward ; it feels like they just took it away for no reason other than market segmentation. Even the 6 core part 6850k had 40 lanes a year ago...

$280 for a 1700 is a steal though. Plus AMD says they'll support am4 for 4 years right? Free ride to zen 2 it sounds like.

Comparing 8 core to 8 core was evem more impressive for AMD.

I think it will hurt even more for Intel when they start comparing 12 and 16 core parts.

Amd will still be half the price, but Intel will have a harder time with the frequency advantage.
 
I am actually dramatically concerned with TDP. I wish someone would standardize a test to IPC of 1... And compare power draw for the same workload.

I need the absolute best single thread IPC to Watt chip for a new small build... At moderate OC levels (say, 3.8 for the Ryzen)
 
Ryzen saw 10-20% (and even 30%!) gaming performance boost with the 20% memory o/c on cpu limited games.

It would be interesting if 3600 mhz would give another small boost.
 
please lets not have the thread get derailed on AMD TDP vs Intel TDP, it's a argument that seems to go no were and most of us dont threat about high TDP, were enthusiast and overclockers we just get bigger coolers

Exactly, this is [H]! Unsurprisingly, shit's gonna need power and get hot if you overclock it.

My spider senses are telling me to get Threadripper over Skylake-X. This video is just compounding that thought.

You are doing it wrong then. You want the lowest wattage use you underclock. Fact is the ZEN core is quite efficient at lower clocks, most chart them being so up to 3.3Ghz with another jump if you will at 3.8Ghz. Cant remember the exact speed but the Stilt reduced the clock and got an impressive score in Cinebench, enough that most though well of mobile/laptop ZEN possibilities.
 
Thanks for posting the video kato, I was expecting the 7820 to be much better than that.
 
Wow, the 7820 is a joke for the price difference. Very minor performance advantages over Ryzen only if you're spending hundreds on a custom cooling setup. Intel really did get caught flatfooted.

If you consider overclock, 7820x is way better. 4.7ghz vs 4.0ghz. Faster IPC / core clock and the ability to run quad channel DDR4 4000+ (something Ryzen can't come close to).
 
It's hard to compare when Ryzen has had more time to mature. X299 is brand new and needs some bios updates and optimization. I guarantee you Ryzen would look like horse shit if you compared Ryzen initial release. 7820 has more IPC and much higher clock speed. It needs some tweaking.
 
SKL-X is not going to get huge performance upgrades with magical bios updates. Much of Ryzen's performance boosts came from the ability to run faster memory. SKL-X scales terribly with clock increases and the extra bandwidth does very little in realworld benchmarks.
 
I'm not buying these benchmarks. I've read several other reviews on the 7820x showing it doing much better compared to the Ryzen 7.

Most reviews still use slow RAM for Ryzen, which has proven to have a big impact on performance.
 
Fanboy stages of grief:
