CPU 7700T Bottleneck?

[Kmpkt]

Hey guys,

Just wanted to get consensus on whether I would expect a 7700T to bottleneck a GTX 1080 when compared with a 7700 or 7700K. My understanding is that at 1440p and/or high detail the GPU will be the determining factor with respect to performance. Cheers,

I use my 6950x at stock most of the time (3ghz base, 3.3ghz boost) and I would expect a 7700T (2.9ghz base 3.8ghz boost) to perform about the same. I OC'd to 4ghz for 1440p 165hz gaming but it wasn't necessary - I'd say a 7700T should be fine.

*Edit*
Paired with a 1080 ti

Using an 8700t with a 1080 Ti on an Asus 3440p@100hz monitor currently. As far as gaming goes, I may be missing a few frames compared to the 8700k she replaced but I can’t tell it. I have been overall pretty surprised by the T chips.

This is the first one I’ve ever had and was kind of scared that it was going to be a neutered k model til I tried it. I think the only time I can really tell a difference is a few seconds longer on bootup, but I have 20+ start up apps (including wallpaper engine: a major hog). But as far as gaming, file transfers between my external drives, and general use I can’t tell a difference.

Is there any special that you replaced the 8700K?

K chips can be configured to be T chips. T chips are just designed to work out of the box at ~35W. Lower the voltage and the multiplier and bam, K becomes T.

^ by doing that you lose the boost clocks compared to a t model from what I read. But you can tune it vs having a locked chip. Not really knowledgeable about any of that though so I’ll defer to you on that.

In my case I broke my 8700k chip and needed a replacement. Actually made a cheesy story topic a month ago lol. The last few months, I’ve been thinking of going real sff (sub 5L) in the near future, and I just took a shot with a 8700t on a whim. And I really can’t complain about it for my use scenario.

You can set core max boost, unless it changed with 8700K. For example, for a quad-core, you can set max multiplier:

44, 42, 38, 34

So single core boost is 4.4, two core 4.2, three core 3.8, and four core 3.4.

I haven't messed with the 8th Gen stuff. Regardless, glad it works well. High clock speed shines more in high Hz, but I'm more of a resolution over Hz.

Ive read about it but never really pushed it. Guilty secret: I always just use the easy OC settings that came with motherboards lol. But single core I can reach 3.9 and all core I believe is 3.7. Looks like an 8400 but with HT on paper. I also like that it can be cooled with a noctua l9i and stay in the 60’s with no tinkering.

With my single 1080 Ti I cant push 100hz in most AAA games in 3440x1440 ultrawide with max settings. But I also couldn’t with the 8700k either. Long as I get 60-80 FPS I am pretty happy.

Btw TC, I know they ain’t the same chip but if you wanted me to run any benchmarks so you can see a comparison, I’d be happy to run them and post results. For a gamer, I don’t think it would be disappointing.

Yeah, I'll probably set up a climbing OC for my 6950x, the amount of control you can have is insane. Given X99/X299's "favored core(s)" system I can probably get my best core really high, even on a teeny air-cooler. I'm hoping that 1 core will hit between 4.5 - 4.8ghz

1c - ???
2c - 4.5GHz+
4c - 4.3GHz+
6c - ~4.0GHz+
8/10c - 3.3 - 4.0GHz depending on how testing goes

I'd love a bench on something where you can find a 8700K/1080ti bench on the net for comparison.
