No FPS Gain on 3080 TI over 2080 Super

[99Carnies]

I am specifically playing Halo Infinite and Destiny 2. I'll provide info pulled from MSI afterburner during Halo since D2 anti cheat doesnt allow overlay. Tried googling and watching videos. But nothing seems to help so I am here posting my own in hopes I can somehow at least achieve a stable 230fp.

 

TLDR:

On 1080p, lowest settings with no thermal throttling on CPU or GPU my 3080 TI is performing the same if not worse than my 2080 super. Only achieving 180fps during the most quite moments. Drivers up to date windows + nvidia. OC i9-9900k at 5ghz, 4x8gb DDR4 @2933mhz and 750w Gold PSU.

Halo Infinite lowest settings maxes out to my fps limit at 230p but consistently drops to average 210fps in gunfights.

Destiny 2 maxes out at 170fps at lowest settings 1080p regardless of whats on screen. Averages 165fps. On my 2080 super set up I used to get a solid 180 on lowest settings.

 

Any helps would be great.

You’re CPU bottlenecked. You’re not going to get better performance until you upgrade your CPU.

You did use Display driver uninstaller before you installed the 3080ti right? Also are you sure the settings are identical? Since when you change GPUS, the settings and such can get reset

That is what they do at 1080p.

 

I have an i9 9900k that had a FTW3 Ultra 2080 ti and a FTW3 Ultra 3080 ti.

This is what it looks like with Shadow Of The Tomb Raider.

 

i9 9900k 

SOTTR      1080p      1440p        4k

2080 ti      168fps      123fps      67fps

3080 ti      169fps      154fps      96fps

 

A 5800x had different results.

 SOTTR      1080p      1440p        4k

2080 ti        160fps      122fps      73fps

3080 ti        198fps      163fps      96fps

You should check some reviews for RTX 3080 vs RX 6800 XT from Hardware Unboxed, basically, high end RTX cards does better at 4K but worse at 1080p/1440p, while AMD cards does better at 1080p/1440p.

This is a trend that I noticed with all RTX 30 series vs RX 60 series cards reviews, AMD does better at lower resolutions and Nvidia does better at 4K.

 

Also, the i9-9900K 's single threaded performance is not that great, lower than an i5-12400 and even i3-12100. As I know, single threaded performance matters more for current games. That might be why your FPS does not increase and the CPU utilization is not at max, because the games do not properly utilize multicores (above 4 cores).

Echoing @jones177and @Dukesilver27-the fact that you're running at 1080p is effectively the problem here. At lower resolutions, you are more likely to run into CPU bottlenecks because of the fact that the GPU is not working as hard to render the frames. As a result, you're more likely to max out your CPU because it's working harder to keep up with the GPU. When you move up in resolution, you have to render more pixels per frame, which taxes the GPU more. Then, the limitation is how many pixels are rendered per frame, which is where the bottleneck effectively comes in. This is the more fundamental reason on top of the architectural reasons why Ampere is "better" at 4K than 1080p/1440p.

 

Once you move far up enough on the product stack, it becomes pointless to buy above a certain tier for 1080p with a i9-9900K. If you want to actually experience gains, I'd suggest upgrading your display before upgrading your CPU. The i9-9900K isn't exactly bleeding edge anymore, but it's a waste to upgrade the CPU if you're still at 1080p since you're pushing into territory where you're not taking visually advantage of any gained frames unless you have a 240Hz+ display (esports black magic nonwithstanding).

So you're thinking I'm maxed out at 50% cpu usage aka 4 out of my 8 cpu cores and it's a CPU bottleneck at 1080p settings? It makes sense especially when my temps are low.

In this case should I switch to AMD and upgrade my motherboard to fit a new AMD chip meant for 1080p/1440p? I don't really care for 4k at the moment so I'm not stressed about getting an Intel CPU for better performance at higher quality.

Personally, I'd wait until Zen 4 comes out and try to snag a Zen 3 platform at a discount. It wouldn't be such a bad plan to get a 5800X3D/X570 board for cheap if you can manage it. I'm contemplating getting a 5900X/higher end X570 board when people start flooding the used market.

 

Then again, whether you'd upgrade to 4K or not isn't an Intel vs. AMD issue, it's an Nvidia vs. AMD issue. Intel chips would serve you just as well in this case. Look into your options and compare against benchmarks to see what would be a better deal for you - Zen 3 at a discount, or an Alder Lake platform?

Yes.

 

I also ran a Strix 3080 with the i9 9900k and at 1440p and 4k in was in between the 2080 ti and 3080 ti but the same at 1080p.

 

SOTTR      1080p      1440p        4k

2080 ti      168fps      123fps      67fps

3080         167fps      144fps      87fps

3080 ti      169fps      154fps      96fps

 

There are games that are not CPU bound at 1080p so the i9 does well in them.

One is Horizon Zero Dawn.

HZD FTW 3080 ti    1080p     1400p       4k

i9 9900k                   155fps    138fps    88fps
5800x                       156fps    138fps    89fps 
5900x                       156fps    138fps    88fps   
i9 11900k                 153fps    137fps    89fps
i9 10900k                 157fps    138fps    87fps

 

These games are less common and most games are somewhere between the two.

The newer chips from AMD and Intel have higher IPC so higher frames at 1080p in CPU bound games. 

 

If you need the frames now and don't mind using Windows 11 get an i9 12900k.  You can also wait for next gen since you are not exactly suffering with the i9.

 

I am waiting for a price drop since the i9 12900k is a little too expensive right now.
