[Solved] I just want to ask before I purchase questions
@mobas07, See this link from Nando with all the bandwidth stats https://egpu.io/best-external-graphics-card-builds/#perf express card is only 4Gbps, and you will be limited in performance vs a desktop but will probably be superior to your integrated graphics. It does depend a bit on your CPU. If it's a quad core ore at least multi threaded it will drive that GPU better. Weak CPU may not give you the best results but yes better than integrated graphics. The RX580 is cheap and awesome but as Nando mentioned might drain power. There is also a RX570, GTX 1060 3GB, GTX 1050TI. You can get them all cheaply and may still give a good gaming experience. It will depend also on what game and what function (EG graphics editing).
EXpress card is better than Mpcie in my opinion as it is much more accessible and easily plugs and plays.
@sabrefv, Thanks for the help, so if I use the RX580 i'll need two of those Dell power supplies right? Also I plan on replacing the stock CPU of the Inspiron 1545 with an Intel T9900
EDIT: The only CPU I can find for a decent price is the T9700 I can wait for a better deal on the T9900 if necessary but i'm now worried about a CPU bottleneck for gaming no matter which one I choose. I plan on using an RX580 but i'm worried about bottlenecking it. What should I do?
first ill list my laptop specs
its a hp 15 da 1030 tu
CPU intel core i5 8th gen (4 cores 8 threads)
GPU Intel UHD 620 (inbuilt graphics)
ram 4gb ddr4 2400 MHz(to be upgraded soon)
egpu accessible ports
1x m.2 nvme PCIe port (unused)
1x PCIe port(currently wifi card plugged in)
So since my laptop has internal graphics (but a nice CPU)I would like to use it for both my daily uses as well as gaming purposes
however, I have been reading a to of DIY egpu and have come across some doubts
1)physical distance of the PCIe port and the CPU (on the motherboard) has to be less for the setup to work (said by Linus tech tips youtube)
2)once connected the GPU cannot be disconnected ever
3)only external monitor can be used after egpu setup
my main purposes for building an egpu setup for my laptop is to have a device which I can carry around and put to simple uses (like watching movies on the inbuilt GPU) and simply plugin the egpu and restart the laptop to enter in some hardcore gaming, so my biggest doubt is that can I use the GPU as hardware which can be plugged in and out by my will and can the PC switch between the internal and external graphics simply on restarting
also, I would love to use my laptop's display while gaming and not an external monitor
if anyone with a similar laptop or significant experience can clear the above doubts for me (bcoz GPUs are still expensive and being a student it would be a huge waste of my money if I buy all the accessories and stuff and finally the setup is not compatible with my laptop)
@mobas07, THe T9700 (2009) is a Core 2 duo CPU before the hyperthreading era with a frequency of 2.80GHz and a passmark of 1170. Even the 3.06Ghz T9900 has a passmark of only 1214. In contrast the oldest 1st gen i5-m520 (2101) has a passmark of 1678 and honestly I wouldnt try(my opinion) to run an RX 580 with that CPU either.
My experience was with a Dell Latitude 6430 i7-3740QM that had a passmark of 5747 and I got good results. IMHO you would bottleneck at half that performance.
You can use any benchmark. I like passmark and am just using one benchmark for comparing apples to apples.
@sabrefv, Okay, I have one other laptop I can try. This one is stronger. It's got an AMD-A10 9600p, 8GB of RAM, and a mini pcie port (though i'll have to remove the wifi card). It's the lenovo ideapad 310-15ABR. But one thing is bugging me, look at this:
but then speccy says this:
So I have no idea if I have one slot of RAM used or 2.
@mobas07, I'm not too concerned about the RAM statistics. I get that a lot. Close your browser tabs while that window is open and it will go down a little b it. Then go to processes on your task manager click on the Memory column and it will show you the process that are consuming most RAM at the top and close them if you can. I had a few opened Chrome processes running in the background. i closed them and got down from 54% to 30%. Chrome is memory hungry. you can look into installing a light browser if that concerns you. Do some googling.
THe CPU isnt the best. Passmark 2269. You will get bottle necking and if you use the mini PCIE where your wifi card is then it will only be 4Gbps. So there will be loss of performance. However, it may still be a playable experience playing games. So i would say Fortnite at low or medium, CSGO, Overwatch most probably. GTA maybe. blackops & battlefield (both CPU intensive) I doubt it. I dont play games. I cant play if my life depends on it but all my kids do and I set up their PCs. For CPU Intensive video editing (I dont do it but you need to look this up if you're going to use it) then it will be slow. With an RX580 you should get a better experience for graphics intensive because even though bandwidth is low I have found that if you use an external monitor the consistency of the transfer still gives for acceptable experience in some cases.
Good news you laptop has a single small cover that exposes the wifi card and RAM. https://cc.cnetcontent.com/inlinecontent/mediaserver/all/042/fcf/042fcfe68b583a637d693b9afb7b34db/original.pdf pgs 39, 40, 42
pg 90 - your wifi card is SW10A11648 or SW10A11641 and they both look the same https://www.amazon.com/FMS-Compatible-SW10A11641-Replacement-300-14isk/dp/B07D325RZB so you will need to get the EXP GDC beast with NGFF if you use that and if you do this. I havent used any other type of EGPU for these situations. I have only ever used express card.

@sabrefv, I wasn't worried about RAM usage, but task manager says I only have one RAM slot and Speccy says I have 2 RAM slots but only 1 has RAM in it. Which one is correct?
Also in terms of games I want to be able to play Sonic Generations, Sonic Lost World and Sonic Forces, along with Paladins, Fortnite and Emulators. I definitely want to be able to use Dolphin emulator and PCSX2 but anything beyond that I can live without.
EDIT: Also forgot to mention Sonic & All Stars Racing Transformed and Team Sonic Racing.
EDIT2: Forgot Apex Legends as well
@mobas07, Both Speccy and Task manger are saying you have a total of 8GB. Speccy is probably pointing out that its single channel (Only 1 DIMM). Its easy to open and see. I use CPU-Z. it should tell you how many DIMMs you have. If you have only one DIMM and can add a second that is one huge way to improve your perfrmance. I will check your laptop on youtube. I cant remember if you can add two DIMMs
Sometimes 4GB is soldered in the Mobo and they give you a 4GB DIMM (for a total of 8GB) which is why speccy might be reporting it that way
@mobas07, from this video (see 5:44) it looks like there is only 1 DIMM and its probably 4GB. Is 4GB is onboard and then 4GB DIMM that explains Speccy's summary
