The GPUs in the following two products have the same name: RTX 3070. One is for a desktop PC and the other is for a gaming laptop. But they don’t even come close to the same performance. What’s going on here? Is this a problem? Let’s start comparing!

Today we tested Nvidia’s new GeForce RTX 3070 notebook GPU, a product already available in many gaming notebooks and the faster and more expensive sibling of the RTX 3060 notebook GPU we reviewed a few weeks ago.

In terms of specifications, the RTX 3070 GPU for laptops does not have the same basic configuration as its desktop counterpart. Both use GA104 silicon, but the desktop GPU has 5,888 CUDA cores, compared to just 5,120 for the laptop version. Boost clocks are also lower than 100 MHz for the laptop version in the best cases, while the 8 GB GDDR6 memory configuration remains the same.
At the end of the day, taking a 220W desktop GPU and pushing it into the 80-125W region requires some sacrifices, and for this generation, that’s both the GPU’s core configuration and clock speed.
Speaking of power, the RTX 3070 laptop GPU is available in different power options that OEMs can use depending on the cooling provided by the laptop. The minimum TGP is 80W – which is the same as the previous version of Max-Q, a designation that Nvidia no longer uses – the maximum is 125W, with many options in between. Additional power can also be sent to the GPU via Dynamic Boost 2.0, so most RTX 30 GPUs have a power range for laptops to work in.
This naming convention can be confusing for laptop buyers as the 80W and 125W options will offer different levels of performance, but in the past few weeks Nvidia has made it mandatory for OEMs to list the GPU’s TGP in laptop specifications. , a significant improvement.

Today we are testing two laptops using the Laptop RTX 3070 GPU – one with a base power rating of 80W and the other with 115W, giving us a good look at the range of possible performance you can get from this GPU.
Dynamic Boost 2.0 provides up to 15W of extra power in both systems when the CPU load is light, so the TGP ranges are 80-95W on the less powerful model and 115-130W on the more powerful model, although the power consumption the general decreases. . in the middle of this range when playing.
Our 80-95W configuration is inside the Gigabyte Aorus 15G, a slim premium gaming system. The Aorus 15G can also run an RTX 3070 at 90-105W, but to keep this review from getting too long, we’ll go with a basic custom configuration that will run the practical range of how the RTX 3070 laptop GPU can run. shows – but customers should note that the Aorus 15G is slightly faster if you install higher mode in the Gigabyte firmware.
I am a big fan of the build quality of this Aorus 15G laptop, the finish has a nice texture and the keyboard is nice. Although it’s portable, it’s not the thinnest chassis out there. It also uses a Core i7-10870H instead of AMD’s newer and faster Ryzen 5000 APUs, although that could be due to availability – Intel’s Gen 10 processors are already shipping, while the Ryzen is less

The RTX 3070 115-130W laptop we’re looking forward to testing is the XMG Apex 17, the upcoming laptop you saw in our Ryzen 9 5900HX review. So inside is a Ryzen APU, with 16 GB of dual-channel DDR4-3200 memory and an RTX 3070 with Dynamic Boost and adjustable BAR.
In today’s review, we’ll also compare these laptops to a regular desktop gaming system with a full GeForce RTX 3070 graphics card inside. The desktop test system is equipped with a mid-range Core i5-10600K processor, which actually has fewer CPU cores than the notebooks we’ve tested — six versus eight for notebooks — though a desktop CPU can certainly clock in. work higher and use. more power. There is also 16 GB of DDR4-3600 memory in a dual-channel version. This will give us a good idea of how close these laptop variants are to the desktop segment of the same name.
We tried in two decisions. The basic configuration runs 1080p using Optimus, which is standard on most laptops today, with some advancements towards smart MUX solutions. This means that the signal from the discrete GPU goes through the integrated GPU to the display. We also tested at 1440p using an external display with a direct connection to discrete graphics for some comparison charts later in the review. This removes the Optimus’ slight performance deficit and also mimics what you’d get on a laptop with a 1440p display and a smart MUX solution like Optimus Advanced.
Our usual laptop reviews apply here, we won’t go over everything again, so let’s get straight to the tests.
How To Buy The Right Graphics Card: A Gpu Guide For 2022
In Metro Exodus, the RTX 3070 laptop GPU does an excellent job of providing more performance than previous generation GPUs. This new 115W TGP version is 40 percent faster than the RTX 2070 and 21 percent faster than the RTX 2070 Super.
It also beats the new RTX 3060 by 14 percent. However, it is not in the same league as the desktop GPU, which is 34% faster than this laptop version.
Meanwhile, the lower version 80W 3070 is actually slightly slower than the 115W RTX 3060 model.
This can be a challenge for buyers when comparing different laptop designs (and well, that makes this review even more useful). Still, it holds its own against other low-powered options, 9% faster than the RTX 3060 and 23% faster than the RTX 2070 Max-Q.

Control’s 115W RTX 3070 notebook GPU is the fastest mobile GPU we’ve tested in a smart form factor. 15% faster than the RTX 3060 and RTX 2070 Super, and 35% faster than the RTX 2070. However, it is less than the desktop RTX 2070 Super and nowhere near the full RTX 3070, which is a single GPU with an average . Get 100 FPS in this title.
In the lower power class, it’s an uphill battle. The 80W RTX 3070 is slightly faster than the 115W RTX 3060, but it ends up ahead of other Max-Q builds: for example, it’s 24% faster than the RTX 2070 Super Max-Q.
In Borderlands 3, desktop GPUs are limited to 1080p, so the benefits on laptop parts are less noticeable. At 115W, the RTX 3070 is 12% ahead of the RTX 3060 and 28% ahead of the RTX 2070, but it can’t match the desktop performance of the RTX 2070 Super in a configuration that also benefits from a desktop CPU.
In Red Dead Redemption 2, some of the smallest gains were going from the RTX 3060 to the RTX 3070 in the 115W power class: the RTX 3070 was only 7 percent faster. This allowed the desktop version to increase the performance of this game by 35%. However, the gains over the previous generation parts are still impressive: 36% higher performance compared to the RTX 2070.

In the lower power class, we see a strong result for the RTX 3070: 15% faster than the RTX 2070 Super Max-Q at 90W, and only 9% ahead of the RTX 3060
Rainbow Six Siege running at 1080p gives us a good idea of how the game looks when the CPU is limited, trying to squeeze as many frames as possible.
In the end, there is not much difference between RTX 3070 and RTX 3060, so people who want to play competitive games at quality settings have no incentive to buy a faster configuration, because the CPU performance is simply there. there is no
The RTX 3070 on the desktop with the unlimited power of the Core i5-10600K completely destroys the notebook settings with a performance increase of at least 65%.

In Assassin’s Creed Valhalla, the RTX 3070 is 15% faster than the RTX 3060 at the same power level, although this performance difference decreases exponentially when compared in the lower power class.
While the RTX 3070 80W is about 10% faster than the RTX 2070 Super Max-Q, it’s one of the less impressive gains we’ve seen so far, and in this game the RTX 3070 desktop is 30% faster or more.
While the RTX 3070 doesn’t offer laptop-like performance in Cyberpunk 2077, it’s more like 60fps compared to the 90fps you’ll get with this GPU on a desktop.
The 3070 is more than 20% faster than the RTX 3060 in both power classes in this game, which is one of the biggest numbers we’ve seen so far.
