deck uses one of the best apus, but its gpu still weak next to a 1030
same for its cpu
also deck display is 1280x800
Which for anyone adverse to doing the math 1280x800 is about half as many pixels as 1920x1080.
It is that, and it's also a pretty severe bottleneck at this point. That poor 1080ti is being mistreated!
You would be surprised how much of a bottleneck it isn't. Sure at 1080p resolution in super CPU intensive scenarios it would be, but then even modern CPUs will bottleneck modern GPUs in those situations.
The i5 4670K isn't the greatest CPU in the world, and is getting pretty old, as it was released in 2013, but the 1080 Ti is getting pretty old as well. Like 5 years old. So, the i5 4670K will not bottleneck the 1080 Ti all that much. Except in the certain situations that I have mentioned. However, I wouldn't want to upgrade that GPU without first upgrading the CPU. The 1080 Ti is about the best GPU I would want paired with a 4670K. Like I said, at 1440p or 4K wouldn't be an issue, but in very CPU intensive games at 1080p, will be a huge bottleneck.
I used to have two GTX 1070s in SLi paired with an i7 4770K, and that CPU didn't bottleneck them whatsoever. Granted the 4770K is better than that 4670K but not that much better. My 4770K could have handled a 1080 Ti easily and I assume so could a 4670K.
As someone with both a 4.8Ghz 2700k and a 4.8Ghz 4790k (both of which are faster with more threads than his) I can tell you that in *many* instances in first hand testing the CPU's are holding back even an RX-6500xt (not the PCIe bus).
Both majorly bottlneck my Vega 64 which is above a 1080 and below a 1080ti. The bottleneck caused by the 4790k was bad enough to cause me to upgrade to the 3900x 2 years back.
in most games made 2018/19 or after his CPU is holding him back, even in older titles like GTA-V his CPU is liable to cause massive dips to his lows.
At OP, your system is better than a steam deck, but overall:
The CPU is weak and needs an upgrade hard. Its basically the same as running an Intel Pentium build with a 1080ti in todays hardware terms.
The GPU is fine enough for just about all uses 1080p/144hz and under, and can do decent duty still in the 1440 range with 60+fps in most cases and high refresh rates in some.
The RAM may or may not suck, depending on the rest of the build. High end DDR3 can perform IRL just as good as some decent DDR4. I run 1866Mhz CL8 in one rig and 2400Mhz CL10 in the other, and both are comparable in Speed:Cas to modern performance kits and outside of raw bandwith can compare well in benchmarks (better in anything timing sensitive).
But if the RAM you have is more economy kit like 1600/cl9 or 1333/cl9 then its kinda poop no matter how you spin it.
If you have a high end Ram kit and a high end Z97 board look into a 4770k/90k as they are OK still. Not great, and not "worth" the cost to a new builder, but they are worth it to someone with an otherwise high end z97 build rocking an i5.
If you have poop ram and an economy motherboard then dont bother, keep the 150 saved on the chip and save another 250 for a motherboard and ram and build a new base build for 300-450 with ram/cpu/mb.
But I assume you are talking about 1080p resolution. Resolution has a big part to play in this. Because like I said, at 1080p, and CPU intensive scenarios, the 4670K would bottleneck the 1080Ti. But I bet you at 1440p or 4K, there wouldn't be one. Maybe at 1440p, to some degree, in CPU intensive games, but not at 4K.
I know. I used to use an i7 4770K with two 1070s, at 1440p, and there was no bottleneck. Now at 1080p, you become very CPU limited. Even modern CPUs will bottleneck GPUs at 1080p. I have a 10700K with a 3070Ti, and at 1440p and 4K, there is no bottleneck. At 1080p, even the 10700K bottlenecks the 3070Ti. Now, before building my new setup, I tried my 3070 Ti with my 4770K, and at 4K there was not much of a bottleneck. I got full GPU usage. But 1080p, and even 1440p, the 4770K bottlenecked the 3070Ti. And even at 4K, in CPU intensive scenarios, I saw some micro stutter using the 4770K that I have not seen with the 10700K.
So, most definitely there will be a bottleneck. But you have to consider what situations and resolution you are playing at. If he is at 1440p, or 4K, I doubt the i5 4670K will bottleneck the 1080 Ti all that much.
People talk about bottlenecks, but you have to consider what resolution you are gaming or testing at. Not all resolutions are created equal. 4K will make the game incredibly GPU limited, for example, and you can usually eliminate any CPU bottlenecks.
Here is a good video that shows CPU bottlenecks. It is with a 10700K and a 3080. Look at 1080p. Now in most games, that are GPU intensive, you are fine, but in the CPU intensive games, you are not getting full GPU usage at 1080. You are running into CPU bottlenecks.

So, you can say that there will be a massive bottleneck. But at what resolution are talking about? Because, like I said, at 1080p there would be a huge bottleneck. At 1440p or 4K, not so much.
But you have a flagship GPU. A 2014 Lamborghini will still beat a brand new 2022 Ford Fiesta in a drag race.
Steam deck has a newer and more powerful CPU and much faster next gen RAM compared to your PC. The GPU, though a lot weaker, is much newer. It technically supports things like raytracing, but I wouldn't bet it can perform very well with raytracing turned on.
but still the 1080 will beat the apus rt abilities
Well, to help with ray tracing, every Steam Deck game will be able to use AMD's FSR. Still even with FSR, I am not too sure you will want to use ray tracing, lol, but FSR will help with performance.
Considering that the Steam Deck res is only 1280 x 800, using FSR in demanding games could help immensely with performance. Still probably won't want to be maxing out settings though. But considering its smaller size, the 1280 x 800 resolution, with FSR, and low-medium settings shouldn't look all that bad on the Deck's screen.
It isn't going to be a high end PC or anything, but if it does well and is successful, meaning Valve will continue to support it down the road, I may eventually get one. I already have a desktop, but if I want some mobile PC gaming, it is cheaper than getting a gaming laptop, and more portable. It is also a lot cheaper than some of those other portable PCs.
Gaming performance wise GTX 1080 Ti's RDNA2 equivalent is Rx 6600xt, which has 32 cu.
So, theoretically Steam Deck's GPU is 4 times slower than the 1080 Ti, which makes it equal to a 1050ti. But, battery operated mobile devices (including laptops) usually come with lower Clock speed due to thermal limitations. So, Steam Deck could be even more slower.
