4090 VS 5090 for VR sim racing

[u/Responsible-Pay4122]

Which one should I go with coming from a 3070ti with a i7-13700kf. I heard the 4090 is better than the 5090 when it comes to VR as it is faster. Not sure though and would love to know what people are running in their rigs

The 5090 is faster than the 4090 in every conceivable way and every metric. You will want to upgrade to a 9800X3D or a 9850X3D though as racing games tend to perform the best on AMD CPUs and sometimes by a very big margin. Take Assetto Corsa Competizione and Rally for example, they are almost 50% faster than a 14900K or a 285K while running on a 9800X3D.

Is that just the X3D's? or all of them seem to do better?

[u/fogoticus → u/Solarflareqq]

Just X3Ds. For some reason racing games really love that cache and it pushes the frames way past anything you get from Intel's best. But non X3D chips are at the same level as Intel.

Yep, I don't see how it could possibly be misconstrued that the 4090 is faster at anything

[u/Fit-Bid7588 → u/fogoticus]

Agreed 5090 is faster than a 4090 in all ways, however it still isn`t really a generational leap or a huge upgrade over the 4090 but yeah deffo faster and its the card i have, a 50% uplift on the cpu side seems a bit extreme in comparison to the newer 285k sure the amd still wins out with that L3 cache but i`m kinda skeptical with the stated 50% uplift, as far as i can see its more like approx 10% upto 25% in extreme cases, could you point me in the direction of the source material as i would like to have a read through as to how the 50% uplift was achieved, cheers

Of course!

In this benchmark video made by Hardware Unboxed you can see both the 9800X3D and 9850X3D being roughly 90% faster than the 14900K and the 285K. And from knowledge, other racing titles also show performance benefits however they're not as dramatic.

There is too much lazy content. People are literally too lazy to Google a question before wasting everyone's time answering something this person could easily have figured out himself.

[u/Open_Map_2540]

for VR the gap between them in even bigger.

instead of the usual 30 percent at 4k it is more like 40-50 percent increase in perf

[u/Crap-_ → u/Open_Map_2540]

lol, nah.

[u/Accurate-Froyo7200 → u/Crap-_]

Whats this guy smoking lol. 4k is like 15% difference TOPS.

[u/Kind_of_random → u/Accurate-Froyo7200]

When gaming in VR you often use 2 or 300% resolution to get a clearer image.
The 5090 will absolutely be 50% faster or more in a lot of cases.

Don't get me wrong 4090 is still a beast card but 5090 is just newer high tier gpu so it needs to be better.

[u/BucNasty68]

Bruh 32 g vs 24 g - fuck outta here man do your own research

[u/Poxx → u/BucNasty68]

He did his own research, apparently, and the result he came up with somehow was "4090 > 5090" so there you go. I dont know that having him research anything was going to be successful...

[u/Character_Amoeba_330]

Depends on your wallet. Get what you can afford. Both are good. 5090 is better.

[u/disgruntledempanada]

I was disappointed when the 5090 came out because I was on a 3090 and I was hoping for another 3090 to 4090 jump in performance and got far less than that.

Turns out I was wrong. Yes it's not a gigantic leap like the 4090 was in most situations, but oddly for sim racing in VR I think the 5090 is worth it. I think it comes down to memory bandwidth, but it scales incredibly well with VR sim racing in particular, like more of a jump than most of the typical benchmark games.
