Benchmarks Find Intel Core i7-7700K Better Than i7-7800X for Gaming

Over at Techspot, Steven Walton managed to get a hold of Intel's new six-core, 12-thread Core i7-7800X CPU, and chose to take it for a spin over a levy of gaming benchmarks. The results don't bode particularly well for Intel's new top i7 offering, though: it is soundly beat by its smaller, svelter brother in virtually all gaming tasks.

Out-of-the-box results are somewhat in line with what we would expect: the Core i7-7700K does bring about a base clock increased by 700 MHz compared to the i7-7800X (4.2 GHz vs 3.5 GHz), and has a higher boost clock to boot (4.5 GHz vs 4 GHz.) And as we've seen over and over again, including with Intel rival AMD's Ryzen offerings, frequency usually trumps core count when it comes to performance when applications are exposed more than four cores. And this leads to Walton's results: the Core i7 7700K is still king in pure FPS terms, coming in with a much more attractive proposition than the 7800X in both minimum and maximum FPS, as well as power consumption.
Now, to be fair, most of us were probably expecting that: consumer application optimization for high core-count processors (if we can actually call a six-core a high core-count processor in a soon to be Threadripper-infused world, but I digress) is sorely lacking. However, what really paints Intel's i7-7800X in a bad light is that its performance continues to be lacking even when it has a frequency advantage over the 7700K. As you can see in the performance metrics, a Core 17-7800X overclocked to 4.7 GHz (with a 500 MHz advantage over stock clocks of the 7700K and 200 MHz over its Boost clock) still performs slower than it. The stock 7700K has 5% higher minimum and maximum framerates than the 7800X, despite being clocked lower, having a ridiculously lower amount of L2 cache, and having about the same total L3 cache (which actually results in an about 30% lower available L3 cache per core.) And these lower frame rates are delivered with a 41% higher idle power consumption, and 23% higher gaming power consumption. Check the source link for some detailed benchmarks. As for all this, it seems that while Intel likes to take digs on AMD for their "glued-together" desktop dies repurposed for servers, Intel's 7800X, which has its cache hierarchy and core interconnect re-architected for servers, may be little more than a repurposed server CPU for the desktop crowds...Source: Techspot

Your whole post is a bunch of nonsense. Sorry dude, try again. Your 3770k is bottleneck in games?? LOL, the most stupid thing I've read in years. :laugh::laugh:
Oh yeah, is a bottleneck if you consider that 150fps (3770k) vs 155fps (7700k) to be bottleneck.
Watch the video above more carefully. The only thing that is the bottleneck in that game is the GPU who is on average at 95% most of the time, while the CPU is 55%.
Please do tell again how the CPUs are a bottleneck in games...:nutkick::shadedshu:
hmm that's pretty interesting. you got some nerve man :) keep it up. when the hell did you see 3770k being 5 FPS behind 7700k? who's taking nonsense here? You can see the utilization of the CPU 100% and FPS drop for a pretty short time but it's there. Nonsense man you made day with that statement clean up your head with crap.

Just to add.
Here's some benchmarks.

and here another real time.

5 fps difference = joke of the year bro.
Add 2k/4k gaming into that equation and let me know what you think of the difference between the two CPU's

Its a blip. its not like it was pegged there... hell it wasn't close most of the time and ran 50-70%...

So, let's think who is trying to make bottlenecks out of blips...

7700K will last one year... you made OUR day with that statement. Clean up your head man! :)

last one year? It will last more year but it will become a bottleneck though you can still use it just as i'm using my 3770k and it is still decent. You still will be able to play with that CPU with nice FPS just as I'm playing with my 3770k. Game will drop FPS just as it is shown on in BF1. FPS does drop.

That is EXACTLY what you said bud... we are just responding.

Better 10 years than 1 year with the 4 core 7700K.

Yeah it's what i did for the second time. And you still didn't get it. Bummer.

Bummer for your word choice. Say what you mean, and mean what you say!!!

BF1 does require more than 4 threads, I'll say that much. Gaming with my 6800k at 4.0GHz was much better in BF1 than it was with my old 2500k at 4.5GHz. Just overall much smoother.

Whether it needs more than 8 threads though, I'm not sure.

Well i did but you rather pull expressions instead reading the post. Whatever man I'm not going to argue with you. That's just what i have noticed and what i think will happen. 7700k is going to be a bottleneck in games(maybe not all of them at once) within a year especially with more powerful GPU's coming next year and that's on the BF1 example. Anyway you can still play using 7700k with decent FPS and stick to this CPU for a longer time.

Decent FPS? It's a lot better than decent.

Expressions? I took it literally. Glad you clarified from your original statement. Since, it will last longer than a year.

What he meant was... he is going to start rendering movies and streaming stuff while he games next year.
