    With only 4GB of ram you'll struggle to even open the Unity editor.

    Please don't. I'm guessing you don't have much to spend on a laptop but there is a limit to how old of a laptop you should consider and that laptop is far beyond that point. Forget Unity. That machine will struggle to run a browser and it will struggle to run Windows.

    Crazy part is the memory is the least worrisome part. AMD's E1-1500 was released in 2013 but it's performance is on the level of a Pentium 4 from 2008. It's graphics is a Radeon HD 7310 which sounds great on paper but is half the performance of Intel HD 4000 which came out in 2011.

    i am currently planing to replace my motherboard to get a i9 12900K processor. should i go with a DDR4 or with a DDR5 motherboard? will it have any speed benefit going with DDR5 over DDR4 - especially in script compilation?

    This isn't a good choice at all. Chances are that there are better offers for the same amount of money (even in the current market) as i've noticed those older laptops being pushed on the market for higher prices than what they are actually worth.

    Not that user, but here's an analogy: an image could be printed using different inks, paper types, resolutions ("low quality displays") but the source of the image (the product made on a "high quality display") must be as close to authors intent as possible to ensure that even on low quality paper, the image is still going to be somehow "accurate".

    Script compilation times mostly depend on raw CPU power. DDR4 or DDR5 will make no difference.

    Trying to decide between two laptops which I'd like to use for both game dev and playing games. (although game dev is the primary goal). Besides Unity I would also want to run apps like Blender and do "regular" stuff like browsing, email, docs etc.

    1) ASUS Rog Zephyrus G15 2022
    Model: ‎GA503Q
    CPU: Ryzen 9 6900HS
    GPU: RTX 3060 (6GB)
    RAM: 40GB
    Storage: 2TB SSD NVMe
    Screen: 15.6" WQHD (2560x1440), 165Hz Refresh Rate
    Weight: 4.21 lbs

    2) Dell XPS 15
    Model:
    CPU: Intel Core i7 (12700h)
    GPU: RTX 3050 Ti (4GB)
    RAM: 32GB
    Storage: 2TB SSD NVMe
    Screen: 15.6" FHD (1920x1200) 60Hz Refresh Rate
    Weight: 4.22 lbs

    The prices at the specs above are comparable.

    The Dell has the 12th gen Alder Lake CPU which has supposedly really good performance which would probably be better for compiling? The ASUS obviously has the better GPU (RTX 3060). Also the Dell can be specced up to 64 GB RAM for an additional $350 whereas the Asus maxes out at 40GB RAM. The Asus GPU can be specced up to RTX 3070 Ti, although I can't seem to find that anywhere at the moment.

    One area that I am confused about in general is storage. It seems that nowadays that every other asset on the asset store weighs in at gigabytes in size. How do people manage to do development with anything less than 2TB? Should I be thinking about 4TB? Is development on a USB-C connected SSD practical? Both laptops can be specced up to 4TB SSD.

    Given that both laptops are (relatively) light, I'm also somewhat concerned about thermals. Even though this would be a game dev laptop, I still think that 75% of the time would be "general computing", i.e. browsing, mail, documents etc. I'm assuming in this scenario given that the GPU doesn't come into the picture, that the Asus (Ryzen 9) would run cooler?

    Any advice would be appreciated.

    ps) My current laptop on which I do Unity dev is a 2 year old Dell XPS 3790 13" . It does not have a dedicated GPU but I've managed to make do. However, the major problem I have with it is that it has a very wide GHZ range. So it will briefly burst up to 4+ GHz and then quickly settle back into the 0.8-1.2 GHz. range. For the longest time I was getting huge performance variation from run to run with no code or asset change. It took me a while to figure out it was because of the CPU variability. Based on this experience it seems to me that the Ryzen might be better because even though it has lower peak performance than the Intel 12th gen, the Ryzen CPU Range (3.0 GHZ-4.6 GHz) seems much narrower than the Intel's (2.3GHz-4.7GHz).

    Are there any best practices when trying to optimize/benchmark one's game when the CPU itself has such a wide range of speed?

    I almost responded that the screen was the best selling point but then I looked up the performance differences between the mobile RTX 3050 Ti and the 3060. According to Tom's Hardware the 3050 Ti is on average 50% slower than the 3060 at 1080p with some games seeing 74 to 115% more performance on the 3060.

    The higher resolution will be more demanding but the card is more powerful so it balances out, and DLSS works better when you have a higher internal resolution which you will thanks to the native resolution being higher.

    https://www.tomshardware.com/news/mobile-rtx-3050-ti-terrible-buy

    I'm also not a fan of the 4GB of the 3050 Ti. Ignoring the mobile market for a moment there are only two desktop cards that have 4GB and both of them are low end models. Every other card has at least 8GB with most of them having at least 12GB. I just don't trust the 4GB of the mobile 3050 Ti having any longevity.

    Thanks, that was helpful.

    still wondering how much ssd developers realistically need especially if they’re using a lot of asset store assets.

    Depends entirely on the size of your project. Also since you're going to play games keep in mind that many modern AAA games take up to 100+ GB of storage. In my opinion 2TB should be enough for most and you should be able to upgrade your storage should it become an issue down the road.

    I wouldn't worry about this at all unless you're planning on buying used hardware that is more than five or so years old because the simple truth is aside from raytracing almost all of the advanced features we work with have been available for years now.

    Performance is far more critical than new features. Compute shaders for example have been available on desktop since 2010 and mobile since 2014 but good luck using HDRP which requires them on a device that old. It won't be pretty if it's even functional.

    OpenGL ES 3.0 is another great example. It's been available on desktop since Intel HD 4000 but just about every phone made in the past few years is at least on par if not faster and Intel HD 630 which is anywhere from 3 to 10 times the performance of HD 4000 is still only at best on par with a recent mid-range phone.

    Want to create games for Android and iOS without having to worry about performance and features for the next few years? Just buy the baseline M1 Mac Mini. It starts at $700 but is frequently on sale for $600 to 650. If that's too much money the 2018 model is still current and supported but it's far slower too.

    I'm thinking of upgrading my 8400. I'd probably need a new PSU, might go for DDR5 so new RAM and a new heat sink. What do you guys recommend below 800$?

    Hello, I am new to Unity, I have a Legion 5 pro, 2022 version with a RTX 3060 and i7, whenever I try to run the unity build, it tends to heat up like crazy, the thermals reach around 95+ degrees and I am worried.

    I know it can be worrisome the first time you see it but this is completely normal for gaming laptops. They're made both to handle high temperatures and hit them while under load. Computers are designed to throttle and then shut themselves off if the temperature becomes too great. If it isn't turning off without warning its fine.

    Edit: It's not just laptops either. Computer components have two things that affect their performance. Temperature and available power. A component will push itself until one of these have been met. A custom built desktop will only rarely hit power constraints which is why reviews often show Intel CPUs sitting at 100C with AMD a little lower.

    I only ever had one proper laptop and that was one of the core duo macbook pros that were heating up their GPU so much that solder joints were starting to weaken. It was repaired free of charge eventually because the screen no longer turned on. Glad to hear stuff is designed better today.

    What do you think of the Lenovo Legion Series in general? I'm looking into buying a PC Laptop for asset creation, gamedev, gaming, composing and writing. RTX3060 is the minimum GPU that I'd want and it needs to have a screen with very good color accuracy and viewing angle, and resolution higher than 1080p would be great. 32GB Ram would be good and easy access to the SSD and a second SSD slot would be a plus. Trying to keep the price in the 1000 to 2000 Euro range. Maybe I'll be able to get a good deal during a prime promotion sale on amazon or something like that.

    I'm still using very old (like way older than 10years) Lenovo TFTs (not sure about the panel type but something *VA I think, no IPS for sure) and I still like them a lot more than the average IPS panel that you can buy today. So I've had good experiences with Lenovo screens and hope that holds true for their laptops too.

    Honestly I had never heard of the series before this thread. At a glance it's basically the same value as an Acer Predator Helios 300, ASUS TUF, or MSI laptop. Amazon is having another prime sale Oct 11th to 12th and Black Friday/Cyber Monday will be here soon.

    I have a 2013 Macbook running Unity 2020 and I was thinking of going over to Unity 2021 to take advantage of some of its features. The problem is while Unity 2020 runs fine 2021 gets the Macbook all hot and bothered, even in a simple empty scene. This problem is compounded when doing multiplayer development having multiple Unity instances running which again is fine in 2020 but 2021 puts the Macbook into meltdown. :D

    Is there any way to reduce the cpu load in 2021 or is it best just to stick with 2020 on this aging Macbook?

    I propose the same discussion created by this guy as mine
    but unlike him, I'm trying to figure out if or which laptop to buy for game development with Unity3D and use of Blender and also for the purpose of playing games.

    My idea was to buy this pc having a budget of about 1300 €
    can anyone advise me?

    I might have an opportunity for my employer to purchase a very high end laptop for unity dev. It would be docked as a desktop station most of the time, but laptop for occasional portability.

    Is it feasible to call this a desktop replacement? The specs are better than my current desktop but I just have this feeling like a laptop pushing out huge gpu work day in/day out is going to heat up and be an issue. Or no?
