Question Is it Wise To Pair A i9-10850K With A 7900 XT Instead of 4090?

[Heat_Fan89]

I went to a website that calculates CPU/GPU bottlenecks and according to them, if I pair my 10850K with a 6950XT, it will produce over 10% CPU bottleneck at 4K. I thought that was a little high since it was released in the same generation as my RTX 3080. My 10850K is essentially a slightly downclocked 10 core 10900K.

What do you guys and or gals think about a 4090 with a 10850K? How severe would the bottleneck be in 4K.

 

[Heat_Fan89]

That sounds GPU related then, there are some exceptions such as ray tracing, volumetric clouds ect.. but usually lowering graphical settings does not help with a CPU bottleneck. Is your GPU usage near 100% when it's running below 60FPS?

I haven't checked but I will. Typically flight sims such as X-Plane and Microsoft Flight Simulator lean more on the CPU side.

I know MS Flight Simulator can, the reason I say to check is if say your GPU is at 70% when the game is running below 60 FPS. Then adding in a new GPU is going to make no difference.

Excellent point !

Is there a utility you prefer to use that is more accurate than others to view both CPU/GPU loads? I thought PC-Builds was a good source for CPU/GPU bottlenecks but some think their calculations are rather bogus as well, especially when a 6900 XT shows less than a 1% bottleneck while the 6950 XT produces close to a 12% bottleneck. I questioned those numbers.

MSI Afterburner is the most accurate. I ignore bottleneck calculators. I don't get too hung up on bottlenecks either, that will swing from CPU to GPU depending on the current workload. The question I would ask is, is your gameplay smooth and are you getting the performance that you want.

OKAY, I could not check X-Plane 12 because I had the early access version and I basically have to reinstall the game again from Steam (60GB). So I will do that later. I ran MSFS 2020 with Ultra settings and using DLSS Quality along with DX 12 Beta.

My OSD read on average more than double the GPU load versus CPU load. Flying out of Chicago Meigs airport (no longer exist IRL but put back in the game). I was seeing around 50-60% GPU load and 9-18% CPU load on the 10850K. That doesn't surprise me tbh because that was a beast of a CPU just a couple of years ago. It was essentially a 100Mhz downclocked version of the 10900K. Memory was about 9.8GB usage.

So at this point it looks like the CPU can easily handle a 7900 XT or XTX. I'm not a big fan of Ray Tracing so I lean more towards rasterization which the 7900 series excels at.

This is why I would be surprised if you ran into issues at the frame rate your targeting. I haven't found a triple A game that the 10850K does not play well even with Ray Tracing and graphics jacked to the maximum.

Decisions, decisions whether to go with a 7900 XT or 7900 XTX? Amazon dropped the price of the 7900 XT from $999 to $899 but the 7900 XTX gets closer to the RTX 4090 but costs a lot more.

I am leaning on AMD this time because I won't have to replace my 850W Corsair Platinum PSU in my Omen 30L if I go with AMD.

 

[mjbn1977]

People worrying too much about bottleneck. As long as you don't use your high end (4080, 4090, 7900XTX) in 1080p, and you using modern games with high graphics setting, its not a big issue (especially if using raytracing). Yeah, you might lose some FPS in 1440p with the older CPU.....but yawn nothing to write home about. Yeah, you will see a few more fps with new high end processors, but shouldershrug they newer so yeah.

In the end it comes down to the question if you want to spend that much money......all depends what you want, but bottleneck is not too much you think about. The question should be, is it overkill for what you try to achieve and is it worth the money.

Can you get hold of a 7900 XTX and what's the price difference?

Is the 7900 XT going to be enough of an increase for you over your 3080?

Amazon this morning was selling them for $1199.99 but now it's just filled with scalper listings, i'll wait. IIRC MSRP was $999, so it looks like the easy choice is the XTX when they become available from Amazon.

Okay so I verified and the 7900 XT is $899 and the 7900 XTX is $999. What the heck was AMD thinking? Seriously?

The 7900 XT is DOA at that price unless they decide to come to grips with reality and reprice them at $600.

I think so because the 6900 XT beat the 3080 in rasterization quite easily and it had 6GB extra of VRAM. The 6950 XT delivered about 10-12% performance gain over the 6900 XT.

The 7900 XT according to Gamers Nexus has about a 25-30% performance gain over the 6950 XT. The XTX version beats them both with a performance gain of about 50-60% depending on the game. So yeah either card would give me a huge to massive improvement over the RTX 3080. And like I said, i'm not all that big on RT. I've seen it in some games and I just say, what's the big deal.

Now where RT might take the next big step is when the Unreal Engine 5 makes its debut. Supposedly it is all about taking advantage of RT.

AMD is finally ready to throw some fresh hardware into the endless battle between Nvidia and AMD for gaming dominance, sure Intel is part of the rumble these days too, but it's fair to say they've got a way to go before they compete on a higher level. While it's pretty much known at this point...

I'm not sure about MS Flight Simulator, a GPU upgrade made not give you a constant 60 FPS. In that test all GPU's were bottlenecked by the CPU and that was with a i9 12900K.

There is a YT video where a gamer was getting a solid 60FPS in MSFS 2020 with a 10850K and 4090 by enabling DLSS 3 and tbh, it really is tough to tell the difference between upscaling vs native. They look so close to each other.

I've got no problem with DLSS 3.0, I use DLSS 2.0 for Cyberpunk. I am surprised that DLSS 3 would be a solution to a CPU bottleneck personally. I don't play it but it seems that with all the settings dialled up every CPU currently available struggles to maintain 60 FPS at 4k.

MFS 2020 is one of the games that do to its "slow" action gameplay, can use DLSS 3 without noticing artificats or other unpleasant screen effects. At least according to people who have tested this on youtube channels like:

View: https://youtu.be/GkUAGMYg5Lw?t=572


A different thing would be to use DLSS 3 with a racing game, which I would not reccommend, but everyone is free to do what they want lol.

DLSS 2 have come a long way now, and if you need it is a really good tool to get some extra frames on older hardware at higher resolution and details settings (like my RTX 2070).

Who knows, may in a few months nvidia finally opens DLSS 3 to atleast the RTX 3xxx series.

 

[kerberos_20]

if hes gonna play on multiple monitors or ultrawide, 4090 might not be overkill..and we are talking about todays games...few years later and it may struggle

 

[mjbn1977]

Why not going with a 4080? they are available at retail and the card is actually very good. Just price. But at $1200 to $1300 it is a much much better product than the 7900 XTX at the same price. Better Thermals, better Raytracing, better efficiency, DLSS 2.0, DLSS 3.0(frame gen), and almost same rasterization performance (3%less average?).

I thought DLSS 3.0 puts not extra strain on the CPU for the extra generated frames? So far I only use it in Flight Simulator (great) and Witcher 3 Next Gen with my 4080. In Witcher 3 Next Gen I don't see artifacts during gameplay, don't feel any issues with lag. But without DLSS 3.0 I get already over 70fps. Mostly play around the technology and am amazed about the +150fps in 1440P with Ultra Settings with Raytracing......

I used to use MS Flight sim with 8700k/RTX2080 combo until recently. I upgraded to 13700k/RTX4080. It is a big improvement, but frame rate is so much depending on things resolution, location (busy 3rd party airport?), type of plane (3rd party study level plain, PMDG?), altitude. It is still not perfect (but what is perfect for Flight Simulator? Do we need +60fps?) without DLSS 3.0. But DLSS 3.0 really improves the experience in MS flight simulator and might actually one of the application where DLSS 3.0 frame generation really makes sense.

My bad. Here is the video I was referring too. He was now getting 140FPS with the 4090 and 10900K. My 10850K is not far off that CPU performance.

Depending on the resolution you using you will not see much difference between a 4090 and 4080 when you are in the CPU main thread limit of the game (which we are all in most of the time in MS flight simulator). Save yourself the $700 and get the 4080. You will have similar framerates. Both have DLSS 3.0 and will double your frames.....and both will be limited by the processor pretty much the same way, and that is why you most likely see now significant difference between 4080 and 4090 in MS flight simulator in processor limited situations. I wouldn't be surprised if even the 4070Ti will be very close in that scenario.....

I'm actually leaning on the 7900 XTX. They are cheaper, they aren't as big as the 3 slot 4xxx monsters. I can still use my current 850W Corsair PSU. I just want to be able to hit 4K at 60FPS. The Radeon's excel in rasterization so I feel good about hitting 60 FPS.

You can use a 850W with the 4080 (it only has a 750 Watts requirement). It is actually using much less power than the 7900XTX and I doubt it will do much more frames than the 4080. But with the 4080 you can activate frame generation which works perfectly well in MS flight simulator and it will basically double your Framerate. The 4080 will run cooler than the 7900XTX

The problem is the size. The card is downright massive. Three slots wide and over 17.5" long.

This are review numbers:

Microsoft Flight Simulator 2020, High Settings, 4K
RTX 4090: 69fps average, 57fps 1% low (DLSS 2 and DLSS 3 Frame generation: 187fps average, 128fps 1% low)
RTX 4080: 68fps average, 55fps 1% low (DLSS 2 and DLSS 3 Frame generation: 174fps average, 121fps 1% low)
7900XTX: 67fps average, 50fps 1% low (Frame generation: not available)

This was done with a 12900k and DDR5. So expect some lower frame rates with your processor.

As you can see, normal frame rates are mostly CPU limited hence the very close number on 4090, 4080 and 7900XTX. But you can use frame generation on the on the 4000 series Nvidia cards. That will double your frame rate. There are tons of youtube videos where they review frame generation on MS flight simulator. you should watch a few....

60fps in 4k...what graphic settings you wanna use?
