Keywords

💡RTX 4070 SUPER

The RTX 4070 SUPER is a new graphics card released by Nvidia. It is an upgraded version of the standard RTX 4070 with improved performance. The video tests the performance of this card compared to the RTX 4070 Ti SUPER in various systems to evaluate bottlenecks.

💡bottleneck

A bottleneck refers to a component in the system that limits the performance of other components. For example, if the CPU is not powerful enough, it can bottleneck the performance of a high-end GPU. The video tests bottlenecks with different CPUs and resolutions.

💡DLSS 3

DLSS (Deep Learning Super Sampling) 3 is an AI rendering technique by Nvidia that boosts frame rates in games. It helps reduce differences in performance due to bottlenecks. Games using DLSS 3 show smaller differences between CPUs.

💡frame rate

The video tests differences in frame rates between systems to evaluate performance. Higher frame rates indicate better GPU performance, but this can be limited by the CPU causing a bottleneck.

💡resolution

The video compares performance at various resolutions - FHD, QHD, and 4K. Bottlenecks are more apparent at lower resolutions like FHD where the GPU is outputting more frames that the CPU cannot keep up with.

💡CPU performance

Faster CPUs like the Core i9-13900K reduce bottlenecks compared to slower CPUs, allowing the full performance of high-end GPUs to be utilized.

💡game performance

The video uses benchmarks and tests in games like Forza Horizon 5 to measure differences in performance between systems. This reflects real-world experience rather than synthetic benchmarks.

💡graphics card upgrade

For users with lower tier systems, the video advises considering the monitor resolution, games played, and purpose of use before upgrading to avoid spending too much money on mismatched components.

💡system balance

Rather than always buying the highest end parts, the video suggests balancing the system - i.e. avoiding bottlenecks by matching the CPU, GPU and monitor to your needs.

💡value for money

The video recommends configurations that offer good performance per dollar rather than chasing the absolute highest frame rates which may be overkill.

Transcripts

Hola! Nice to meet you.

After the RTX 4070 SUPER and 4070 Ti SUPER were released,

I think there are various evaluations.

At least, the 4070 SUPER can be viewed positively, but the 4070 Ti SUPER is in a very sad situation.

In any case, as various opinions can be expressed about the same product, it is

also for me. We are receiving various requests from our subscribers.

First, quite a few subscribers who purchased the collaboration PC we ran on our channel some time ago

asked what it would be like to change the graphics card to the RTX 4070 SUPER or RTX 4070 Ti SUPER... and

how to upgrade.

So, in this video, we will take a look at the RTX 4070 Ti SUPER.

We are also testing the 4070 SUPER, so we would appreciate your patience.

First, the product used in this test is Emtech's RTX 4070 Ti SUPER Gaming Pro model.

Looking at the packaging, there is a 16-pin conversion gender.

Two 8-pin power cables are used.

You're used to it now, right?

Also, there is a cable for RGB sync.

The design is no different from previously released models.

It is a triple fan configuration, and the basic black color is finished with all RGB-lit parts made of acrylic.

It has a metal backplate and

the output ports consist of three DP 1.4a ports and one HDMI 2.1 port.

The thickness is 3 slots. It's pretty thick.

You may have checked the embargo review regarding spec changes and performance.

If you are curious about the differences from the existing 4070Ti or 4080, please check the embargo review.

In this video,

we will be conducting a test based on the requests of people who purchased the collaboration PC that we ran on our channel some time ago.

The specifications of the collaboration PC

were a model equipped with Intel 14600KF, DDR5 5600 32GB, and RTX 4060Ti.

Of course, you can use it as is, but I think I was most curious about this.

The 4070 SUPER and 4070 Ti SUPER have also been released, but

if I use it with the graphics card installed as is, will there be any difference from using it in a 14900K system?

If so, how many? That part.

In fact, this is a very important part, but most of you have heard of it being a bottleneck, and some

people may even vaguely understand it as something like using the CPU.

Since there are so many different stories related to this bottleneck,

some of them are a bit like urban legends,

and some people are stubborn and fight over the stories they just heard. So,

I don't know what the difference is between using the 4070 Ti SUPER in the 14600KF and 14900K you're thinking of, but

let's take a look at them one by one.

The test system is as follows:

Before testing, we ran the latest BIOS patch and Windows update, and

version 551.23 of the driver used in the test was used.

First, let's look at the 3D Mark bench test results.

Let's start with Time Spy, which is a DX 12 standard test. You

have to take the test resolution into consideration, and

Time Spy is a test based on 2560x1440 QHD resolution.

If you just look at the graph, the difference looks quite large. It's an illusion, right?

The graphics score for 14600KF was 24139 points and for 14900K it was 24213 points.

There is a 74 point difference, but you can just view this as being equal.

In Time Spy Extreme, a test based on 3840x2160 resolution,

the 14600KF scored 11893 points and the 14900K scored 11931 points.

This also has an 83-point difference, but if you look at the results alone, this can be considered the same.

If you look at the time spy test results alone, there really isn't much of a difference, right?

This is because this is the graphics score standard,

but if the CPU test was also performed and viewed as a comprehensive score, there would have been a difference.

I was also going to look at the fire strike score...

but this led to some interesting situations, so I'll pass on the fire strike score.

This didn't happen when I used the test version of the driver... but after applying the official version driver,

the score only jumped in Fire Strike... so

the score is going crazy like now, right?

Usually, when testing, each item is run at least 20 times and

the results are checked, and the highest and lowest scores are excluded and

the score that comes out the most is reflected in the average line

. Even if there is a deviation, this is the first time I have seen a case like this...

Anyway, for this reason, Fire I will leave out the strike side.

In the case of Fire Strike Ultra, which is a test based on 3840x2160 resolution,

the score difference is 20 points... . no see.

If you look at the PAS this way, it's just the same level.

Anyway, if you look at the graphic score alone, it's the same level? uh… . So does that mean it's the same in QHD or 4K?

You might be thinking:

However, you should not judge based on this alone.

The performance shown in the actual game will be important, and the results may vary from game to game.

Let's take a look at what it would have been like in game.

First, these are the FHD resolution results of Forza Horizon.

You can see that there is a difference of more than 10 frames between the average frame and the 1% frame section.

This difference is similar to the difference between 4070Ti and 4070 Ti SUPER.

When I say it this way, the difference seems quite big, right?

Next is the QHD resolution result.

You can see that the difference between the average frame and the 1% frame section has decreased.

Still, there is a difference of about 7 frames on average, and

this difference can be considered to be about the same as the difference between the 70 Ti and 70 Ti SUPER.

So, although it is the same graphics card, this difference occurs due to the difference in CPU.

Now let’s look at 4K resolution.

You can see that there is no difference at 4K resolution.

So, at this point, we need to think about the reason why bottlenecks occur.

We will explain the bottlenecks in detail later, but to put it simply

here, whether it is the CPU or GPU,

the balance is broken and the performance of certain hardware is affected by the performance of other hardware. It occurs when it is higher.

A common expression is to hold back the 4070Ti SUPER.

Looking at the results in FHD and QHD,

you can see that the 4600KF is holding back the 4070Ti SUPER.

Fortunately, in the case of Forza Horizon

, the gap did not get wider because it used DLSS3 .

Next, we will look at Battlegrounds, a title that does not apply DLSS.

FHD resolution.

If you look at the average frame, you can see that there is a difference of more than 60 frames.

Huge difference, right?

Is this the same graphics card? You can see that it has expanded to the extent that you would like, so

let's move on to QHD resolution.

You can see that the average frame gap has been reduced to almost 30 frames.

As the resolution increases, the difference gradually decreases, right?

However, it still shows a very big difference.

At this level, you can see that the graphics card is of a different level.

Next is 4K resolution.

Now you can see that it has been reduced to almost 7 frames.

A frame difference of this magnitude is actually difficult to feel when playing games.

You will just feel like you are using the same card.

If you look at this point, frame differences occur due to bottlenecks at low resolutions

, and the differences are larger in titles that do not support DLSS compared to titles that support DLSS3.

Anyway, there would be this much of a difference, right? You might have thought, but the difference was probably bigger than you expected.

However, there are exceptions.

Let's think about it for a moment.

The larger the output frame, the more performance differences occur due to bottlenecks.

Are the output frames large? That means the GPU does its job well, right?

Literally, the better the GPU works, the less the CPU can keep up with its speed.

So what if it's a tough game that doesn't produce many frames to begin with? Will this gap narrow?

So what if it's a tough game that doesn't produce many frames to begin with? Will this gap narrow?

This is Sifeng 2077.

You can see that there is almost no difference in FHD resolution.

What about QHD?

There is almost no difference even in QHD.

What about 4K?

4K doesn't make much of a difference either.

Rather, in 4K, the average frame rate was slightly higher at 14600KF.

Why?

If you look at the results of games such as PUBG or Forza that were tested before Safeng,

you can see that the difference is significantly reduced in the 100 frame

range when looking at just the frame rate, excluding the resolution

. If you think about this simply, at the level where the 4070 Ti SUPER processes images at 150 images per second,

the 14600KF follows without much difference compared to the 14900K.

I can work hand and foot to that extent~ Well, something like this.

In the case of Safeng 2077, the frames shown at three resolutions

are all less than 150 frames when considering DLSS3 frame generation.

At QHD resolution, you will be able to see it at less than 100 frames.

Therefore, it can be said that the results showed almost no difference.

However, there are exceptions.

The difference may vary depending on what kind of game it is.

This is Assassin's Creed Mirage. This is a title that only has DLSS 2 applied.

It's not a game with a lot of frames to begin with.

However, there is a difference of close to 20 frames in FHD.

So, it should be around 170 frames, but due to a bottleneck, it dropped to around 150 frames.

Although the difference has been reduced in QHD, the performance is about 15 frames lower.

At 4K, the performance is almost identical.

So, the difference is only in how much the difference is, but in any case, a bottleneck occurs in FHD or QHD.

Looking at it this way, Sifeng could be seen as a unique case.

Lastly, this is a game that was released recently.

Like the dragon, it is 8.

The reason I included this game is because I'm personally a fan of the Dragon Like series... but also

because it's a game equipped with DLSS3.

When looking at FHD, there is a difference of about 50 frames.

Here, let's remember that the larger the frame unit, the bigger the difference due to the bottleneck.

Even if the frame rate is blown due to DLSS 3, if you look at just 50%, it is almost 180 frames.

If you look at the comparisons so far, this is the section where the bottleneck occurs.

In QHD, there is almost no difference.

Considering DLSS3, it can be seen as a native 150 frame rate, but

since DLSS3 is applied here, the difference has been significantly reduced.

Of course, this formula doesn't apply to all games, but you can roughly estimate it like this.

In 4K resolution, it's just the same.

Looking at it this way, it may still feel a bit complicated, but it will become a little more organized.

If the RTX 4070 Ti SUPER is

used on a FHD or QHD resolution monitor,

a bottleneck will occur in a system equipped with 14600KF.

Rather, if you are using a 4K monitor, you do not need to worry too much.

After doing the bottleneck test like this, it's clear that I shouldn't use that graphics card with my CPU...

To use that, you need to have a CPU of roughly this size. There will be people who

say this. That's not wrong, but if

you think about it simply that way. It's absolutely right to use a high-performance CPU, and

after investing in a high-performance CPU, shouldn't it still be of this class? With that in mind,

you will go for a high-performance GPU.

In the end, a huge amount of money will be spent just to build the system, ignoring the purpose of use.

Therefore, I would like to tell you to think about the balance of the system first.

Considering the purpose of my use, the games I usually play, monitor specifications, etc.,

I think it is important to have the most waste-free configuration that

achieves the level of performance I want.

First of all, I will explain the bottleneck in detail later. I will do it.

There is a lot of talk about this and many people have incorrect information,

so we will make time to study together.

If you watched today's test, you would have felt that

the 4070 Ti SUPER is mainly QHD, supports

4K 60 frames, and

is a compatible card for those who have a 4K 144Hz monitor environment based on DLSS 3 standards.

In this environment, the range of CPU choices can be expanded and

the performance loss due to bottlenecks can be considered acceptable to some extent.

For subscribers who purchased a collaboration PC, it is not recommended for use in an FHD environment.

There is a performance loss in a QHD environment, but it can be used at this level.

Use a 4K environment... . Well, I guess I can say this.

Well then, I'll come back with another video.

Thank you very much for watching.

It's been Ato so far.

Have a happy day

ah... . And, the game test video continues. Please refer to it.
