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....

That is why some manufacturer has a power supply tester that include undervolt and overvolt.


Yeah? I leave them alone for over a years. For record, I do not get harassment warning.

Undervolting only becomes an issue if you go too low, that’s a fact, people don’t need to drop their voltage by much and most often they stick to a voltage that it normally runs regardless.

My new computer doesn't let me go undervolt in the BIOS like my old computer used to except I saw 1.1 V, so it can't have been an undervolt if you still can use lower voltage than default.

And I told you I said "Could".

When it is too low voltage which is undervolt, then IC or PSU may trying to draw more current which can also overheating some component. It probably won't damage it literally, but it could.

It "could". If you're using an absolute dumpster tier piece of hardware with no voltage regulation.

That doesn't apply to modern gpus.

Huh? Many good quality GPUs have quality voltage regulation, but some has a switch mode that the input voltage can't be undervolt that far. Zero voltage regulation GPUs doesn't exist, but counterfeit GPUs may does.

GPU tweaking isn’t done in BIOS. We aren’t tweaking garbage iGPs here.

So what you're saying is undervolting a gpu isn't dangerous because they have voltage regulation.

Glad we sorted that out.

I didn't said that.

Undervolt mean it is below the manufacturer declared voltage rate.

Low voltage mean it is below the normal voltage, but within the declared voltage rate.

Yeah but most people don't need more than 4 cores.

Win10/11 runs like dog-crap on old stuff with 4-cores. We have not had 4 cores in the mainstream since 8th Gen came out. It's dead. Even phones have an 8-Core; cmon. Look at all the Ryzen Laptops. And they run so well and super-smooth.

Yes, I do.

I proved my evidence in here. Low voltage and undervolt are not same. Also, if you have a datasheet to prove that what you set voltages is considered as an undervolt due to outside the operating voltage, then by all mean.

[ZAP]

Those 6000 Radeons clock super high on air and people are saying the next ones will too.

There's actual software to overvolt, you don't have to voltmod or flash a custom vbios to go even further either.

Most people don't what a core is.

It seems like there's all these ballers online but that's because it's PC related. IRL nobody knows what this stuff is.

You haven't proven a damn thing except you don't understand what undervolting is.

Yes, I understand the different between undervolt and low voltage, and "low voltage" is a correct word to use. Most article you saw are probably not an EE, so please forever me if I can't take their word for it. Undervolt could stressed IC and corrupted data while low voltage does not.

Most of the components use a graph of voltages and frequencies. So let's say at 2000MHz the voltage should be 1.35V, but if we drop it to 1.2V isn't it already below the manufacturer's operating speed?

Except the correct term when you're talking about gpu tweaking is undervolting.

You have no idea what the hell you're on about.
