Thoughts on Nvidia's Geforce RTX 4080...

[ZeekAncient]

I was wondering what people thought of the RTX 4080.

I have been reading some initial reviews, and I have some mixed feelings on it myself.

Here are some of the reviews that I have read:

https://www.tomshardware.com/reviews/nvidia-geforce-rtx-4080-review

https://www.techspot.com/review/2569-nvidia-geforce-rtx-4080/

https://www.pcgamer.com/nvidia-rtx-4080-16gb-review-performance-benchmarks/

I have read some others, but I figured I would post these as their scores vary from one an other and they provide the same important and relevant info as other review you will find.

The consensus is that the 4080 provides excellent gen-on-gen performance increases over the 30 series, and compared to the 4090, is very power efficient, and probably more worth purchasing if you are eyeing resolutions lower than 4K, like 2560 x 1440.

At 4K, it can be less than 30%% less powerful than an RTX 4090, however still a great performer at 4K, outperforming the flagships of the last generation.

However, it seems to be way overpriced. Obviously not a surprise here, as I think everyone was expecting this to be the case. But with the advent of AMD's 7900XTX, and 7900XT, to be released for $999, and $899, respectively, I was wondering what you all thought about the 4080's performance and how it should compare to AMD's RDNA3 offerings.

Some seem to think that even the 7900XTX will fall short of the 4080's overall performance, while others think that AMD's flagship will easily outperform the 4080 in rasteriztion performance, but fall short when it comes to ray tracing.

While most don't seem to care about ray tracing, or upscaling tech for that matter, I for one DO care about ray tracing performance, and love upscaling tech, especially at 4K. Most games nowadays are going to have some kind of ray tracing implemented, and more and more newer titles are going to be implementing it better, and more so. I don't think it will be very long before we see games completely rendered with ray-tracing. And not just older games like Quake II and Portal.

So, I think ray tracing performance is very important, and I don't want my next generation GPU to fall flat in that area. So, that is why I am very curious to see how AMD's next GPUs will perform in that area. I mean, if the 7900XTX can outperform the 4080 in rasterization but then be more on the level of the 40 series midrange cards when ray tracing is implemented, that might turn me off.

And then when it comes to upscaling tech, I am very interested in what DLSS 3.0 has to offer. DLSS 2.0 is already fantastic, but the performance gains that 3.0 seem to be providing, almost seem like a game changer. Considering that DLSS 3.0 can only be used on 40 series cards, unlike FSR which can be used on any card, FSR 3.0 might need to be a game changer as well if I am going to consider buying an AMD card.

I have been on Nvidia a long time, but I will be wanting to upgrade my GPU when I upgrade my display to a 4K 120Hz+ display. The RTX 4090 is just too expensive and too power hungry for me to realistically consider it. And while the 4080 seems to push all the right buttons for me when it comes to performance and power consumption, even it it still uses the 16-pin power connector, that $1199 price tag, and even more when you consider AIB cards, is way too overpriced.

If it would have been $999, or less, I think it would have been a no brainer. But it will be hard to drop $1200 or more on a GPU, when AMD's $999, or even $899, offering provide better rasterization performance. Not too mention more VRam. Even if the ray tracing will not be quite as good, and DLSS 3.0 will be a no no.

I've been impressed by what the specs, and price, of the 7900XTX and XT have shown but I guess now it all depends on how well it will perform in ray tracing and how good, and how well adopted, FSR 3.0 will be. I guess we will have to wait and see in December.

I'm kind of one that would like to stick with Nvidia since I have been there for so long, and it is comfortable for me, even with Nvidia's shady business practices, but $1200 or more for a GPU is just too much to stomach. The 4080 really should have been $200-$300 bucks cheaper. But if AMD falls flat in ray tracing, and FSR 3.0 just can't match the quality of DLSS 3.0, I just can't see myself going the AMD route. Might have to wait for Nvidia to come to their senses and drop their prices....

I might be waiting long....

Anyway, those are my very long two cents on the matter...sorry....

You can undervolt the 4090 to get it running in 650 and 750 watt PSUs, it’s fine on 850W if you manage consumption. Linus managed to get it working on a 550W unit IIRC.

I do not recommend undervolt because it could stressed the drive in order to supplying correct voltage.

Don’t care what you think. If you don’t want people going after you, don’t reply to them and try to correct them on something the industry can dispute. Take your own advice and leave people alone, otherwise, I will destroy you at every turn.

When you leave me alone for good first.

I’ll leave you alone when you stop going after people for trivial things that boil down to the user’s opinion, and going after my friends and trying to correct them when you have no idea what you’re talking about. So effectively won’t happen until you either leave the forum or get permabanned for your antics. You’re the instigator 75% of the time.

[Seamus]

Good to know james doesn't know what undervolting is any more than anything else he's tried to talk about.

As for the 4080: Might be worth the investment if the price takes a steep drop(And who knows, it may. They're not selling.)

And I will still refused being your follower. People can ignore me, why cant you too? They can either accept or not accept my post. If you don't like my advice, then that is fine. But please stop make a big deal out of it. They say everyone is welcome, so don't get angry with me for that.

Yes, I know what undervolt mean. It mean it is below the declared voltage range.

In case if you don't understand how math work.
0.7 V of 0.8 V to 1.1 V is considered as undervolt.
1.2 V of 0.8 V to 1.1 V is considered as overvolt.

Those voltage could put your component in risk.

0.85V of 0.8 V to 1.1 V with 0.9 V normal is considered as within the range voltage but it is not undervolt.

I am actually curious about undervolting a GPU. It seems like all the rage right now, lol. Because traditionally, especially when overclocking, you wanted to up the voltage to get the best results.

Like right now with my 3070 Ti, I use EVGA Precision, and I have various OC profiles. But I was just playing COD, and I was using an OC profile that has +160 on the core, for a 2130Mhz Boost Clock. +900Mhz on the memory. I have the Power Limit target and GPU temp targer all the way up, for 105% and 90C respectively. And I put the voltage slider all the way up to 100. Everything is stable and runs fine.

Obviously, I have my custom fan profiles to keep everything nice and cool. The hottest the card got after a 20-30 min session was 59.1C, the memoy got to 64.0C, and the hotspot was at 69.8C. So obviously, pretty decent temps.

But I was wondering, where would undervolting make sense? Like would it make sense on my 3070 Ti? I understand how it would make sense if you were trying to get a 4090 to work on a PSU like mine, which is 750W. But is it just if you want to keep the heat down, and fans down as well? Like if fan noise bothered you? Obviously fan noise does not bother me.

So, like I was saying, lol, would undervolting benefit me in any way? Is undervolting a GPU something you would do if were trying to get better performance? Or is overclocking my GPU the traditional way, like I am doing, still the best for what I am looking for?

I am just curious about it, and if it is something that would benefit me in anyway. Like I said, I am not necessarily trying to get my thermals or noise levels down. I just want the best possible performance I can get out of my GPU.

Undervolting isn't going to damage your hardware. Again: You don't know what you're talking about.

Yes, I do. Undervolting could stressed the driver with more current in order to supplying a correct voltage. I work with electric engineering a lot and they warned me not to do undervolting for a lot of thing when I did a hobbies stuff. That is why the company had assembler testing power supply for undervolt.

That is how my old motherboard need repair from undervolt damage.

That is not how gpus function.

You're not going to damage a gpu by undervolting it.

Will, can, and could are all different. I just said undervolt could stressed component. For example, Integrated circuit.

https://www.howtogeek.com/805771/what-is-undervolting-gpu-or-cpu/

Here are two articles about undervolting your GPU. And they both say that the chance of hurting your computer hardware from undervolting is basically zero.

In fact, they both say that it could help with stability, throttling, and potentially prolong the life of your GPU. However, just as overclocking can increase instability and produce artifacts, so can undervolting if you go too far.

See, what will hurt computer hardware, or shorten a components lifespan, is excessive heat. Upping the voltage is what would increase the heat output. Lowering the voltage would theoretically decrease the heat output. So, how could that damage your hardware? It couldn't.

That's not how voltage control on a video card works.

Undervolting is safe.

Overvolting can be dangerous.

Couldn’t care less about you being a “follower” or not. I would much prefer you just disappear and stop harassing people, including friends of mine, all because they don’t agree with your misguided opinions and so-called facts you derived from making microwaves catch fire.

Undervolting is the new overclocking, because OC headroom is basically gone without dropping thousands into a huge custom loop or LN2.

It helps reduce power consumption, and undervolted 4090 is the best deal you can get because you can make it quite efficient with minimal performance loss.
